- Abstract
Objective: One of the most commonly used tools to measure fatigue is the Multidimensional Fatigue Inventory (MFI). Studies into the scale structure of the MFI show discrepant findings. The objective of this study was to investigate the scale structure of the MFI in the general Dutch population., Study Design and Setting: Using data from a Dutch probability-based internet panel (n = 2512), the original 5-factor model, a 4-factor, and a 5- and 4-bifactor model of the MFI were tested with confirmatory factor analyses. Additional models were investigated using exploratory factor analysis., Results: Results neither confirmed a 5-factor (RMSEA = 0.120, CFI = 0.933, TLI = 0.920) nor a 4-factor model (RMSEA = 0.122, CFI = 0.928, TLI = 0.917). The two bi-factor models also showed a poor fit (bi-4-factor: RMSEA = 0.151, CFI = 0.895, TLI = 0.873; bi-5-factor: RMSEA = 0.153, CFI = 0.894, TLI = 0.871). Exploratory factor analysis did not support an alternative model, but seemed to show robustness in the loading of the original general fatigue items., Conclusion: Our results did not provide empirical support for a four or five (bi-)factor structure of the MFI, nor for an alternative model. The most reliable scale of the MFI seems to be the general fatigue scale that could be used as a general indicator of fatigue., (Copyright © 2021 The Authors. Published by Elsevier Inc.

- Abstract
Background: BRCA1/2 mutation carriers are recommended to undergo risk-reducing salpingo-oophorectomy (RRSO) at 35 to 45 years of age. RRSO substantially decreases ovarian cancer risk, but at the cost of immediate menopause. Knowledge about the potential adverse effects of premenopausal RRSO, such as increased risk of cardiovascular disease, osteoporosis, cognitive dysfunction, and reduced health-related quality of life (HRQoL), is limited., Objective: The aim of this study is to assess the long-term health effects of premenopausal RRSO on cardiovascular disease, bone health, cognitive functioning, urological complaints, sexual functioning, and HRQoL in women with high familial risk of breast or ovarian cancer., Methods: We will conduct a multicenter cross-sectional study with prospective follow-up, nested in a nationwide cohort of women at high familial risk of breast or ovarian cancer. A total of 500 women who have undergone RRSO before 45 years of age, with a follow-up period of at least 10 years, will be compared with 250 women (frequency matched on current age) who have not undergone RRSO or who have undergone RRSO at over 55 years of age. Participants will complete an online questionnaire on lifestyle, medical history, cardiovascular risk factors, osteoporosis, cognitive function, urological complaints, and HRQoL. A full cardiovascular assessment and assessment of bone mineral density will be performed. Blood samples will be obtained for marker analysis. Cognitive functioning will be assessed objectively with an online neuropsychological test battery., Results: This study was approved by the institutional review board in July 2018. In February 2019, we included our first participant. As of November 2020, we had enrolled 364 participants in our study., Conclusions: Knowledge from this study will contribute to counseling women with a high familial risk of breast/ovarian cancer about the long-term health effects of premenopausal RRSO. The results can also be used to offer health recommendations after RRSO., Trial Registration: ClinicalTrials.gov NCT03835793; https://clinicaltrials.gov/ct2/show/NCT03835793., International Registered Report Identifier (irrid): DERR1-10.2196/24414., (©Lara Terra, Maartje J Hooning, Bernadette A M Heemskerk-Gerritsen, Marc van Beurden, Jeanine E Roeters van Lennep, Helena C van Doorn, Joanne A de Hullu, Constantijne Mom, Eleonora B L van Dorst, Marian J E Mourits, Brigitte F M Slangen, Katja N Gaarenstroom, M Carola Zillikens, Tim Leiner, Lizet van der Kolk, Margriet Collee, Marijke Wevers, Margreet G E M Ausems, Klaartje van Engelen, Lieke PV Berger, Christi J van Asperen, Encarna B Gomez-Garcia, Irma van de Beek, Matti A Rookus, Michael Hauptmann, Eveline M Bleiker, Sanne B Schagen, Neil K Aaronson, Angela H E M Maas, Flora E van Leeuwen.

- Abstract
Background: We performed a comprehensive assessment of the psychometrics of the "Psychosocial Aspects in Hereditary Cancer" (PAHC) questionnaire in French, German and Spanish., Methods: Women consecutively approached in Cancer Genetic Clinics completed the PAHC, distress and satisfaction questionnaires at pre-testing (T1) and after test result disclosure (T2). In addition to standard psychometric attributes, we assessed the PAHC ability to respond to change (i.e. improvement or deterioration from T1 to T2) in perceived difficulties and computed minimal important differences (MID) in PAHC scores as compared with self-reported needs for additional counselling., Results: Of 738 eligible counselees, 214 (90%) in France (Paris), 301 (92%) in Germany (Cologne) and 133 (77%) in Spain (Barcelona) completed the PAHC. A six-factor revised PAHC model yielded acceptable CFA goodness-of-fit indexes and good all scales internal consistencies. PAHC scales demonstrated expected conceptual differences with distress and satisfaction with counselling. Different levels of psychosocial difficulties were evidenced between counselees' subgroups and over time (p-values < .05). MID estimates ranged from 8 to 15 for improvement and 9 to 21 for deterioration., Conclusion: The PAHC French, German and Spanish versions are reliable and valid for evaluating the psychosocial difficulties of women at high BC risk attending genetic clinics., (© 2019 John Wiley & Sons Ltd.)

- Abstract
Germline TP53 mutations are associated with an increased risk of early-onset breast cancer. Traditionally, it was not standard practice to offer TP53 genetic testing due to the low mutation detection rate and limited options regarding preventive screening. Recent guidelines recommend that all women diagnosed with breast cancer before the age of 31, irrespective of family history, should be offered TP53 genetic testing. This study aims to gain more knowledge on the attitudes and experiences among genetics professionals regarding the timing and content of genetic counselling of young breast cancer patients for Li-Fraumeni syndrome (LFS). We conducted a nationwide online survey among genetics professionals who provide cancer genetic counselling in the Netherlands. Fifty-seven professionals completed the questionnaire (response rate overall 54%, clinical geneticists 70%). Most respondents reported that they discuss the option of TP53 genetic testing-simultaneously with BRCA 1/2-during the initial counselling visit, especially in case of referral for treatment-focused genetic counselling. There was a general consensus about ten information items that should be discussed during counselling. Sixty-one percent of genetics professionals did not encounter difficulties in providing genetic counselling for LFS, but a substantial minority (29%) did. This study offers valuable insight, which will be useful for clinical practice. Studies which address young breast cancer patients' attitudes and preferences regarding the timing and content of counselling are warranted to further determine the most appropriate genetic counselling strategy for these women.

- Abstract
Purpose: Supportive interventions to enhance return to work (RTW) in cancer survivors hardly showed positive effects so far. Behavioral determinants might have to be considered in the development of interventions to achieve sustained employability. This study aimed to explore cancer survivors' perspectives and experiences regarding behavioral determinants of RTW and continuation of work., Materials and Methods: In this qualitative study, semi-structured telephone interviews were held with 28 cancer survivors. All participants were at working age, 1-2 years after diagnosis and employed at time of diagnosis. Thematic content analysis was performed., Results: Work turned out to be a meaningful aspect of cancer survivors' life, and most participants reported a positive attitude towards their job. Social support to RTW or to continue working was mainly received from family and friends, but pressure to RTW from the occupational physician was also experienced. Changes in expectations regarding work ability from negative to positive during the treatment process were observed. Those who applied active coping mechanisms felt equipped to deal with difficulties regarding work., Conclusions: Behavioral determinants should be taken into account in the development of future interventions to support cancer survivors' RTW. However, the causal relationship still has to be determined. Implications for rehabilitation Factors influencing occupational motivation among cancer survivors need to be understood in more detail. Previous studies in non-cancer populations have demonstrated that behavioral determinants, such as a positive attitude towards work, high social support and self-efficacy may increase return to work rates or shorten the time to return to work. Addressing behavioral determinants in future development of work-related interventions for cancer survivors is essential in achieving sustained employability.

- Abstract
Background: Second primary malignancies are a major cause of excess morbidity and mortality in cancer survivors. Hodgkin lymphoma survivors who were treated with infradiaphragmatic radiotherapy and/or high-dose procarbazine have an increased risk to develop colorectal cancer. Colonoscopy surveillance plays an important role in colorectal cancer prevention by removal of the precursor lesions (adenomas) and early detection of cancer, resulting in improved survival rates. Therefore, Hodgkin lymphoma survivors treated with infradiaphragmatic radiotherapy and/or high-dose procarbazine could benefit from colonoscopy, or other surveillance modalities, which are expected to reduce colorectal cancer incidence and mortality. Current knowledge on clinicopathological and molecular characteristics of therapy-related colorectal cancer is limited. The pathogenesis of such colorectal cancers might be different from the pathogenesis in the general population and therefore these patients might require a different clinical approach. We designed a study with the primary aim to assess the diagnostic yield of a first surveillance colonoscopy among Hodgkin lymphoma survivors at increased risk of colorectal cancer and to compare these results with different screening modalities in the general population. Secondary aims include assessment of the test characteristics of stool tests and evaluation of burden, acceptance and satisfaction of CRC surveillance through two questionnaires., Methods/design: This prospective multicenter cohort study will include Hodgkin lymphoma survivors who survived ≥8 years after treatment with infradiaphragmatic radiotherapy and/or procarbazine (planned inclusion of 259 participants). Study procedures will consist of a surveillance colonoscopy with removal of precursor lesions (adenomas) and 6-8 normal colonic tissue biopsies, a fecal immunochemical test and a stool DNA test. All neoplastic lesions encountered will be classified using relevant histomorphological, immunohistochemical and molecular analyses in order to obtain more insight into colorectal carcinogenesis in Hodgkin lymphoma survivors. The Miscan-model will be used for cost-effectiveness analyses., Discussion: Evaluation of the diagnostic performance, patient acceptance and burden of colorectal cancer surveillance is necessary for future implementation of an individualized colorectal cancer surveillance program for Hodgkin lymphoma survivors. In addition, more insight into treatment-induced colorectal carcinogenesis will provide the first step towards prevention and personalized treatment. This information may be extrapolated to other groups of cancer survivors., Trial Registration: Registered at the Dutch Trial Registry (NTR): NTR4961 .

- Abstract
It is important to adequately and timely identify individuals with cancer worries amongst participants in a pancreatic ductal adenocarcinoma (PDAC) surveillance program, because they could benefit from psychosocial support to decrease distress. Therefore, the aim of this study was to assess both psychosocial and clinical factors associated with cancer worries. High-risk individuals participating in PDAC-surveillance were invited to annually complete a cancer worry scale (CWS) questionnaire which was sent after counseling by the clinical geneticist (T0), after intake for participation in PDAC-surveillance (T1), and then annually after every MRI and endoscopic ultrasonography (EUS) (T2 and further). Analyses were performed to identify factors associated with cancer worries in the second year of surveillance (T3). We found a significant intra-individual decrease in cancer worries (β = -0.84, P < 0.001), nevertheless, 33 % of individuals had a CWS-score ≥14 at T3. We found one factor significantly associated with cancer worries at T3: having a family member affected by PDAC <50 years of age (β = 0.22, P = 0.03). The detection of a cystic lesion, a shortened surveillance interval, or undergoing pancreatic surgery did not lead to more cancer worries (P = 0.163, P = 0.33, and P = 0.53, respectively). In conclusion, this study identified 'a family history of PDAC <50 years of age' as the only predictor of cancer worries experienced after 2 years of surveillance in individuals at high risk of developing PDAC. This knowledge could help clinicians to timely identify individuals 'at risk' for high levels of cancer worries who would likely benefit from psychosocial support., Competing Interests: The authors declare that they have no conflict of interest. Ethical approval All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards. Informed consent Informed consent was obtained from all individual participants included in the study. Research involving human participants The Ethical Committee of all participating centers approved the study protocol and the study was conducted in accordance with the Declaration of Helsinki. All participants gave written informed consent prior to the performance of any study-related investigations.

- Abstract
Background: When assessing the feasibility of surveillance for pancreatic cancer (PC), it is important to address its psychological burden. The aim of this ongoing study is to evaluate the psychological burden of annual pancreatic surveillance for individuals at high risk to develop PC., Methods: This is a multicenter prospective study. High-risk individuals who undergo annual pancreatic surveillance with magnetic resonance imaging (MRI) and endoscopic ultrasound (EUS) were invited to complete questionnaires to assess motivations for participating in surveillance, experiences with participation, perceived PC risk, topics of concern, and psychological distress. Questionnaires were sent after intake for participation (T1), after the first MRI and EUS (T2), and after the MRI and EUS 1 (T3), 2 (T4), and 3 years (T5) after first surveillance., Results: In total, 140 out of 152 individuals returned one or more of the questionnaires (response 92%); 477 questionnaires were analyzed. The most frequently reported motivation for participating in surveillance was the possible early detection of (a precursor stage of) cancer (95-100%). Only a minority of respondents experienced MRI and EUS as uncomfortable (10% and 11%, respectively), and respondents dreaded their next EUS investigation less as surveillance progressed. Respondents' cancer worries decreased significantly over time, and both their anxiety and depression scores remained stable and low over the 3-year period of follow-up., Conclusions: The psychological burden of pancreatic surveillance is low at all assessments. Therefore, from a psychological point of view, participation of high-risk individuals in an annual pancreatic surveillance program is feasible.Copyright © 2015 John Wiley & Sons, Ltd., (Copyright © 2015 John Wiley & Sons, Ltd.)

- Abstract
Inconclusive genetic test results including screening recommendations for the breast cancer patients and their first-degree relatives are the most common outcomes of BRCA 1/2 testing. Patients themselves should communicate these results to their relatives. Our aim was to explore communication of breast cancer genetic counseling results with daughters and sisters over a long period of time. Breast cancer patients, who had received an inconclusive DNA test result 7-14 years earlier, completed a self-report questionnaire. Additionally, in-depth interviews were conducted and analysed thematically. Of the 93 respondents, 85 (91 %) considered themselves responsible for communicating genetic test results to relatives. In-depth interviews (n = 14) showed, that counselees wanted 'to hand over' their responsibilities to communicate the test results and screening recommendations to their sisters. Although most patients had informed their daughters and sisters about the genetic test results, usually little is spoken about genetic test results and screening recommendations once the duty of informing is completed. We recommend that, similar to the procedure for BRCA1/2-mutation carriers, a separate letter for first-degree relatives of patients with an inconclusive test result should be provided. In this way information about risks and screening recommendations can be verified by family members years after genetic testing has been completed.

- Abstract
Purpose: Female breast cancer patients carrying a BRCA1/2 mutation have an increased risk of second primary breast cancer. Rapid genetic counseling and testing (RGCT) before surgery may influence choice of primary surgical treatment. In this article, we report on the psychosocial impact of RGCT., Methods: Newly diagnosed breast cancer patients at risk for carrying a BRCA1/2 mutation were randomized to an intervention group (offer of RGCT) or a usual care control group (ratio 2:1). Psychosocial impact and quality of life were assessed with the Impact of Events Scale, Hospital Anxiety and Depression Scale, Cancer Worry Scale, and the EORTC QLQ-C30 and QLQ-BR23. Assessments took place at study entry and at 6- and 12-month follow-up visits., Results: Between 2008 and 2010, 265 patients were recruited into the study. Completeness of follow-up data was more than 90%. Of the 178 women in the intervention group, 177 had genetic counseling, of whom 71 (40%) had rapid DNA testing and 59 (33%) received test results before surgery. Intention-to-treat and per-protocol analyses showed no statistically significant differences between groups over time in any of the psychosocial outcomes., Conclusions: In this study, RGCT in newly diagnosed breast cancer patients did not have any measurable adverse psychosocial effects.

- Abstract
Only a minority of individuals who undergo cancer genetic counseling experience heightened levels of psychological distress, but many more experience a range of cancer genetic-specific psychosocial problems. The aim of this study was to estimate the prevalence of such psychosocial problems, and to identify possible demographic and clinical variables associated significantly with them. Consenting individuals scheduled to undergo cancer genetic counseling completed the Psychosocial Aspects of Hereditary Cancer (PAHC) questionnaire, the Hospital Anxiety and Depression Scale (HADS) and the Distress Thermometer (DT) prior to or immediately following their counseling session. More than half of the 137 participants reported problems on three or more domains of the PAHC, most often in the domains 'living with cancer' (84%), 'family issues' (46%), 'hereditary predisposition' (45%), and 'child-related issues' (42%). Correlations between the PAHC, the HADS and the DT were low. Previous contact with a psychosocial worker, and having a personal history of cancer were associated significantly with HADS scores, but explained little variance (9%). No background variables were associated significantly with the DT. Previous contact with a psychosocial worker, and having children were significantly associated with several PAHC domains, again explaining only a small percentage of the variance (2-14%). The majority of counselees experience specific cancer genetic counseling-related psychosocial problems. Only a few background variables are associated significantly with distress or psychosocial problems. Thus we recommend using the PAHC or a similar problem-oriented questionnaire routinely in cancer genetic counseling to identify individuals with such problems.

- Abstract
Approximately 70% of counselees undergoing cancer genetic counseling and testing (CGCT) experience some degree of CGCT-related psychosocial problems. We evaluated the efficacy of an intervention designed to increase detection and management of problems 4 weeks after completion of CGCT. In this randomized, controlled trial, 118 participants completed a CGCT-related problem questionnaire prior to an - audiotaped - telephone session with their counselor 1 month after DNA-test disclosure. For those randomized to the intervention group (n = 63), a summary of the questionnaire results was provided to the counselor prior to the telephone session. Primary outcomes were discussion of the problems, counselors' awareness of problems, and problem management. Secondary outcomes included self-reported distress, cancer worries, CGCT-related problems, and satisfaction. Counselors who received a summary of the questionnaire were more aware of counselees' problems in only one psychosocial domain (practical issues). No significant differences in the number of problems discussed, in problem management, or on any of the secondary outcomes were observed. The prevalence of problems was generally low. The telephone session, combined with feedback on psychosocial problems, has minimal impact. The low prevalence of psychosocial problems 1 month post-CGCT recommends against its use as a routine extension of the CGCT procedure., (© 2014 John Wiley & Sons A/S.

- Abstract
Purpose: This study evaluated the efficacy of a cancer genetics–specific questionnaire in facilitating communication about, awareness of, and management of psychosocial problems, as well as in lowering distress levels., Methods: Individuals referred to genetic counseling for cancer at two family cancer clinics in The Netherlands were randomly assigned to an intervention or a control group. All participants completed the psychosocial questionnaire before counseling. In the intervention group, the counselors received the results of this questionnaire before the counseling session. All sessions were audiotaped for content analysis. Primary outcomes were the frequency with which psychosocial problems were discussed, the genetic counselors’ awareness of these problems, and their management. Secondary outcomes included cancer worries and psychological distress, duration and dynamics of the counseling, and satisfaction., Results: The frequency with which psychosocial problems were discussed with 246 participating counselees was significantly higher in the intervention group (n = 127) than in the control group (n =119; P = .004), as was the counselors’ awareness of psychosocial problems regarding hereditary predisposition (P < .001), living with cancer (P = .01), and general emotions (P < .001). Counselors initiated more discussion of psychosocial problems in the intervention group (P < .001), without affecting the length of the counseling session. No significant differences were found on management (P = .19). The intervention group reported significantly lower levels of cancer worries (p = .005) and distress (p = .02) after counseling., Conclusion: The routine assessment of psychosocial problems by questionnaire facilitates genetic counselors’ recognition and discussion of their clients’ psychosocial problems and reduces clients’ distress levels.

- Abstract
Background: Up to three-quarters of individuals who undergo cancer genetic counseling and testing report psychosocial problems specifically related to that setting. The objectives of this study were to develop and evaluate the screening properties of a questionnaire designed to assess specific psychosocial problems related to cancer genetic counseling., Methods: We adopted the European Organisation for Research and Treatment of Cancer Quality of Life Group guidelines to develop the Psychosocial Aspects of Hereditary Cancer (PAHC) questionnaire, a 26-item questionnaire organized into six problem domains: genetics, practical issues, family, living with cancer, emotions, and children. The Distress Thermometer and a question per domain on the perceived need for extra psychosocial services were included as well. We administered the questionnaire and the Hospital Anxiety and Depression Scale to 127 counselees at the time of genetic counseling and 3 weeks after DNA test disclosure. As a gold standard to evaluate the screening properties of the questionnaire, participants underwent a semi-structured interview with an experienced social worker who assessed the presence and severity of problems per domain., Results: A cutoff score representing responses of 'quite a bit' or 'very much' to one or more items within a given problem domain yielded moderate to high sensitivity across domains. A cutoff of 4 on the Distress Thermometer yielded high sensitivity. The questions regarding the perceived need for extra psychosocial services yielded high specificity and negative predictive values., Conclusion: The Psychosocial Aspects of Hereditary Cancer questionnaire in combination with the Distress Thermometer can be used as a first-line screener for psychosocial problems within the cancer genetic counseling setting., (Copyright © 2014 John Wiley & Sons, Ltd.)

- Abstract
Genetic counseling and DNA testing (GCT) for breast cancer is increasingly being actively offered to newly diagnosed patients. Little is known about the consequences of such an approach. Therefore, the long-term psychosocial and medical impact of referring breast cancer patients for GCT during an early phase of treatment was studied. A group of 112 breast cancer patients who had been actively offered GCT during adjuvant radiotherapy 7-14 years earlier, returned a self-report questionnaire. We compared their experiences with a group of 127 breast cancer patients who had not met the criteria for GCT. In total, 239 women participated in this long-term follow-up study (72% response rate). Nearly 75% of them had received regular mammography surveillance in the past 3 years. Preventive surgery was reported more often in the counseling group (specifically in the BRCA1/2 mutation carriers). Like the comparative group, only a minority of patients who had received GCT were experiencing high levels of depression (5%) or psychological distress (14%). Breast cancer patients can be actively approached and referred for GCT at the beginning of their radiotherapy without a threat to psychological functioning in the long term., (© 2013 John Wiley & Sons A/S.

- Abstract
Approximately 25% of individuals undergoing genetic counseling for cancer experiences clinically relevant levels of distress, anxiety and/or depression. However, these general psychological outcomes that are used in many studies do not provide detailed information on the specific psychosocial problems experienced by counselees. The aim of this review was to investigate the specific psychosocial issues encountered by individuals undergoing genetic counseling for cancer, and to identify overarching themes across these issues. A literature search was performed, using four electronic databases (PubMed, PsychInfo, CINAHL and Embase). Papers published between January 2000 and January 2013 were selected using combinations, and related indexing terms of the keywords: 'genetic counseling', 'psychology' and 'cancer'. In total, 25 articles met our inclusion criteria. We identified the specific issues addressed by these papers, and used meta-ethnography to identify the following six overarching themes: coping with cancer risk, practical issues, family issues, children-related issues, living with cancer, and emotions. A large overlap in the specific issues and themes was found between these studies, suggesting that research on specific psychosocial problems within genetic counseling has reached a point of saturation. As a next step, efforts should be made to detect and monitor these problems of counselees at an early stage within the genetic counseling process.

- Abstract
Background: Female breast cancer patients with a BRCA1/2 mutation have an increased risk of contralateral breast cancer. We investigated the effect of rapid genetic counselling and testing (RGCT) on choice of surgery., Methods: Newly diagnosed breast cancer patients with at least a 10% risk of a BRCA1/2 mutation were randomised to an intervention group (offer of RGCT) or a control group (usual care; ratio 2 : 1). Primary study outcomes were uptake of direct bilateral mastectomy (BLM) and delayed contralateral prophylactic mastectomy (CPM)., Results: Between 2008 and 2010, we recruited 265 women. On the basis of intention-to-treat analyses, no significant group differences were observed in percentage of patients opting for a direct BLM (14.6% for the RGCT group vs 9.2% for the control group; odds ratio (OR) 2.31; confidence interval (CI) 0.92-5.81; P=0.08) or for a delayed CPM (4.5% for the RGCT group vs 5.7% for the control group; OR 0.89; CI 0.27-2.90; P=0.84). Per-protocol analysis indicated that patients who received DNA test results before surgery (59 out of 178 women in the RGCT group) opted for direct BLM significantly more often than patients who received usual care (22% vs 9.2%; OR 3.09, CI 1.15-8.31, P=0.03)., Interpretation: Although the large majority of patients in the intervention group underwent rapid genetic counselling, only a minority received DNA test results before surgery. This may explain why offering RGCT yielded only marginally significant differences in uptake of BLM. As patients who received DNA test results before surgery were more likely to undergo BLM, we hypothesise that when DNA test results are made routinely available pre-surgery, they will have a more significant role in surgical treatment decisions.

- Abstract
Background: Individuals with a personal or family history of cancer, can opt for genetic counseling and DNA-testing. Approximately 25% of these individuals experience clinically relevant levels of psychosocial distress, depression and/or anxiety after counseling. These problems are frequently left undetected by genetic counselors. The aim of this study is to evaluate the efficacy of a cancer genetics-specific screening questionnaire for psychosocial problems, the 'Psychosocial Aspects of Hereditary Cancer (PAHC) questionnaire' together with the Distress Thermometer, in: (1) facilitating personalized counselor-counselee communication; (2) increasing counselors' awareness of their counselees' psychosocial problems; and (3) facilitating the management of psychosocial problems during and after genetic counseling., Methods: This multicenter, randomized controlled trial will include 264 individuals undergoing cancer genetic counseling in two family cancer clinics in the Netherlands. Participants will be randomized to either: (1) an intervention group that completes the PAHC questionnaire, the results of which are made available to the genetic counselor prior to the counseling session; or (2) a control group that completes the PAHC questionnaire, but without feedback being given to the genetic counselor. The genetic counseling sessions will be audiotaped for content analysis. Additionally, study participants will be asked to complete questionnaires at baseline, three weeks after the initial counseling session, and four months after a telephone follow-up counseling session. The genetic counselors will be asked to complete questionnaires at the start of and at completion of the study, as well as a checklist directly after each counseling session. The questionnaires/checklists of the study include items on communication during genetic counseling, counselor awareness of their clients' psychosocial problems, the (perceived) need for professional psychosocial support, cancer worries, general distress, specific psychosocial problems, satisfaction with care received, and experience using the PAHC questionnaire., Discussion: This study will provide empirical evidence regarding the efficacy of a relatively brief psychosocial screening questionnaire in terms of facilitating personalized communication, increasing counselors' awareness, and optimizing management of psychosocial problems in the cancer genetic counseling setting., Trial Registration: This study is registered at the Netherlands Trial Register (NTR3205) and ClinicalTrials.gov (NCT01562431).

- Abstract
Background: In 9% to 34% of cancer patients, the fear of cancer recurrence becomes so overwhelming that it affects quality of life. Clinicians need a brief questionnaire with a cutoff point that is able to differentiate between high- and low-fearful survivors., Objective: This study investigated if the Cancer Worry Scale (CWS) could serve as an instrument to detect high levels of fear of recurrence in female breast cancer survivors., Methods: One hundred ninety-four female breast cancer patients were assessed up to 11 years after their primary treatment for cancer. The women returned the questionnaires including the 8-item CWS, 2 items of the Cancer Acceptance Scale, the Checklist Individual Strength-Fatigue subscale, and the Cancer Empowerment Questionnaire., Results: A cutoff score of 13 versus 14 (low: ≤13, high: ≥14) on the CWS was optimal for detecting severe levels of fear of recurrence. A cutoff score of 11 versus 12 (low: ≤11, high: ≥12) was optimal for screening. The Cronbach α coefficient of the CWS was .87; evidence to support the convergent and divergent validity of the CWS was also obtained. The CWS is able to detect high levels of fear of recurrence., Conclusion: The CWS is a reliable and valid questionnaire to assess fear of recurrence in breast cancer survivors., Implications for Practice: With the CWS, it is possible for nurses to screen breast cancer survivors for severe levels of fear of cancer recurrence. Thereby, nurses can screen and assist survivors in accessing appropriate and available support.

- Abstract
Specific clinical questions rise when patients, who are diagnosed with breast cancer, are at risk of carrying a mutation in BRCA1 and -2 gene due to a strong family history or young age at diagnosis. These questions concern topics such as 1. Timing of genetic counseling and testing, 2. Choices to be made for BRCA1 or -2 mutation carriers in local treatment, contralateral treatment, (neo)adjuvant systemic therapy, and 3. The psychological effects of rapid testing. The knowledge of the genetic status might have several advantages for the patient in treatment planning, such as the choice whether or not to undergo mastectomy and/or prophylactic contralateral mastectomy. The increased risk of developing a second breast cancer in the ipsilateral breast in mutation carriers, is only slightly higher after primary cancer treatment, than in the general population. Prophylactic contralateral mastectomy provides a substantial reduction of contralateral breast cancer, although only a small breast cancer specific survival benefit. Patients should be enrolled in clinical trials to investigate (neo)-adjuvant drug regimens, that based on preclinical and early clinical evidence might be targeting the homologous recombination defect, such as platinum compounds and PARP inhibitors. If rapid testing is performed, the patient can make a well-balanced decision. Although rapid genetic counseling and testing might cause some distress, most women reported this approach to be worthwhile. In this review the literature regarding these topics is evaluated. Answers and suggestions, useful in clinical practice are discussed., (Copyright © 2013 Elsevier Ltd. All rights reserved.)

- Abstract
In the care of patients with Lynch Syndrome (LS), a range of psychosocial issues are encountered, which significantly affect patient outcomes. A brief historical background of 'psycho-onco-genetics' (the domain where psychology, oncology and genetics meet) in relation to LS is presented, followed by an overview of important psychosocial issues identified in the past 20 years. The identification of mismatch repair genes in 1993-1994 made possible genetic counseling and testing for patients who had cancer and for potentially high-risk relatives without cancer. At that time, concerns were raised about the potentially negative psychosocial impact of predictive genetic testing. Since 1993, a large number of studies have been conducted to investigate the possible psychosocial benefits and limitations of such testing. This article presents an overview of: the uptake of and motivations for genetic testing, its psychosocial impact (e.g. psychological adaptation, impact on risk perception and self-concept, and concerns about, and experiences of, genetic discrimination), psychological screening instruments, adherence to and decision-making about preventive strategies, family communication, lifestyle changes, reproductive technology utilization, and professional psychosocial support needs of members of families with LS. Finally, challenges for the future are discussed, including population screening and genomic testing.

- Abstract
Objective: Female breast cancer patients carrying a BRCA1/2-mutation have an increased risk of second primary breast and ovarian tumors. Little is known about the psychological impact and treatment consequences of rapid genetic counseling and testing offered between breast cancer diagnosis and surgery., Methods: Female breast cancer patients, who had received rapid genetic counseling (and optional testing) (RGC(T)) at The Netherlands Cancer Institute between 2004 and 2008, received a questionnaire in 2009., Results: BRCA-mutations were found in 10 of the 26 participants. Six mutation-carriers (60%) had an immediate bilateral mastectomy, compared with 25% of those without a mutation. Five patients (19%) reported having frequent worries about cancer recurrence; none indicated that such worries impaired daily functioning. Six patients had clinically relevant levels of breast cancer-specific distress at the time of assessment., Conclusion: These results suggest that RGC(T) in high-risk breast cancer patients may influence surgical treatment, without causing long-term psychosocial distress in the majority., Practice Implications: These results are important, since rapid genetic counseling and testing are expected to be offered to newly diagnosed breast cancer patients with increasing frequency in order to inform these women and their surgeons about the possible familial/hereditary nature of their disease before deciding on treatment., (Copyright © 2012 Elsevier Ireland Ltd.

- Abstract
Purpose: : The success of any surveillance program depends not solely on its technological aspects but also on the commitment of participants to adhere to follow-up investigations, which is influenced by the psychological impact of surveillance. This study investigates the psychological impact of participating in a pancreatic cancer surveillance program., Methods: : High-risk individuals participating in an endoscopic ultrasonography-magnetic resonance imaging-based pancreatic cancer surveillance program received a questionnaire assessing experiences with endoscopic ultrasonography and magnetic resonance imaging, reasons to participate, psychological distress, and benefits and barriers of surveillance. High-risk individuals were individuals with a strong family history of pancreatic cancer or carriers of pancreatic cancer-prone gene mutations., Results: : Sixty-nine participants (85%) completed the questionnaire. Surveillance was reported as "very to extremely uncomfortable" by 15% for magnetic resonance imaging and 14% for endoscopic ultrasonography. Most reported reason to participate was that pancreatic cancer might be detected in a curable stage. Abnormalities were detected in 27 respondents, resulting in surgical resection in one individual and a shorter follow-up interval in five individuals. Surveillance outcomes did not influence cancer worries. Overall, 29% was "often" or "almost always" concerned about developing cancer. Six respondents (9%) had clinical levels of depression and/or anxiety. According to 88% of respondents, advantages of surveillance outweighed disadvantages., Conclusions: : Although endoscopic ultrasonography is more invasive than magnetic resonance imaging, endoscopic ultrasonography was not perceived as more burdensome. Despite one third of respondents worrying frequently about cancer, this was not related to the surveillance outcomes. Anxiety and depression levels were comparable with the general population norms. Advantages of participation outweighed disadvantages according to the majority of respondents. From a psychological point of view, pancreatic cancer surveillance in high-risk individuals is feasible and justified.

- Abstract
Objective: Li Fraumeni syndrome (LFS) and Von Hippel-Lindau disease (VHL) are two rare hereditary tumor syndromes, characterized by a high risk of developing multiple tumors at various sites and ages for which preventive and treatment options are limited. For partners, it may be difficult to deal with the on-going threat of tumors in both their spouse and children. Therefore, this study aims to evaluate the prevalence of and factors associated with psychological distress among partners of individuals with or at high risk of LFS or VHL., Methods: As part of a nationwide, cross-sectional study, partners of individuals diagnosed with or at high risk of LFS or VHL were invited to complete a self-report questionnaire assessing distress, worries, and health-related quality of life., Results: Fifty-five (58%) of those high-risk individuals with a partner consented to having their partner approached for the study. In total, 50 partners (91%) completed the questionnaire, of whom 28% reported clinically relevant levels of syndrome-related distress. Levels of distress and worries of the partners and their high-risk spouse were significantly correlated. Younger age and a lack of social support were also associated significantly with heightened levels of distress and worries. The majority of partners (76%) believed that professional psychosocial support should be routinely offered to them., Conclusions: Approximately one-quarter of the partners exhibit clinically relevant levels of distress that warrant psychological support. The distress levels of the 'patient' could potentially be used to identify partners at risk of developing clinically relevant levels of distress., (Copyright © 2011 John Wiley & Sons, Ltd.)

- Abstract
Purpose: To assess compliance with a periodic surveillance regimen for Von Hippel-Lindau disease., Methods: In this nationwide study, Von Hippel-Lindau disease mutation carriers and those at 50% risk were invited to complete a questionnaire assessing (compliance with) advice given for periodic surveillance. Medical record data on compliance with recommended radiologic surveillance examinations were also collected., Results: Of the 84 (77%) participants, 78 indicated having received advice to undergo periodic surveillance. Of these, 71 reported being fully compliant with that advice. In 64% of the cases, this advice was only partially consistent with published guidelines. Based on medical record data, between one quarter and one third of individuals did not undergo surveillance as recommended in the guidelines for central nervous system lesions and one half for visceral lesions. Screening delay for central nervous system lesions was significantly higher in one hospital and in those cases where "the advice given" deviated from the guidelines., Conclusions: The majority of those with or at risk of Von Hippel-Lindau disease reported having received and being fully compliant with screening advice. However, in many cases, the advice given was only partially consistent with published guidelines, and screening delays were observed. Efforts should be undertaken to stimulate guideline-based surveillance advice and to minimize screening delay.

- Abstract
Aim: The study aimed to document the impact of familial adenomatous polyposis (FAP) on health-related quality of life (HRQOL) and several practical aspects of daily life, and to identify factors significantly associated with HRQOL. This study is the first to compare HRQOL between patients with FAP, at-risk individuals and noncarriers., Method: A total of 525 individuals (response rate 64%) from 145 families at high risk for FAP completed a battery of self-report questionnaires assessing generic- and condition-specific HRQOL and the consequences of FAP for daily life., Results: HRQOL was comparable to that of the general Dutch population. Surgically treated patients with FAP had significantly lower scores on several HRQOL domains compared with at-risk individuals, noncarriers and nonsurgically treated patients with FAP. Type of surgery was not significantly associated with HRQOL. Within the surgically treated group, postsurgical complications and comorbidity significantly affected HRQOL. Forty-one percent of patients reported that FAP had affected their working life., Conclusion: Surgically treated patients with FAP have significantly poorer HRQOL than other groups. The type of surgery and age at time of first surgery were not associated with HRQOL but surgical complications and comorbidity were. Patients should be informed of the consequences of FAP for work and other life domains., (© 2011 The Authors.

- Abstract
Objective: Familial adenomatous polyposis (FAP) is a genetic condition characterized by the development of multiple adenomas in the colorectum that could lead to colorectal cancer. Our aim was to assess levels and predictors of psychological distress and quality of life (QOL) among partners of FAP-patients., Methods: A nationwide, cross-sectional survey using validated self-report questionnaires assessing psychological distress and QOL., Results: One hundred and twenty-nine partners completed the questionnaire (84% response rate), 30% of whom reported moderate-to-severe levels of distress. The partners' distress was associated significantly with the patients' distress, having children, and feelings of guilt. Fifty-seven percent of the partners with moderate-to-severe distress levels had received professional psychosocial support. Partners did not differ significantly from the general population in QOL. However, 9-21% reported that FAP had affected their work, leisure time activities, and relationships., Conclusions: Clinicians should be particularly alert for heightened distress levels in partners of patients who are themselves distressed, and among those with children., (Copyright © 2010 John Wiley & Sons, Ltd.)

- Abstract
Background: It has been estimated that between 5% and 10% of women diagnosed with breast cancer have a hereditary form of the disease, primarily caused by a BRCA1 or BRCA2 gene mutation. Such women have an increased risk of developing a new primary breast and/or ovarian tumor, and may therefore opt for preventive surgery (e.g., bilateral mastectomy, oophorectomy). It is common practice to offer high-risk patients genetic counseling and DNA testing after their primary treatment, with genetic test results being available within 4-6 months. However, some non-commercial laboratories can currently generate test results within 3 to 6 weeks, and thus make it possible to provide rapid genetic counseling and testing (RGCT) prior to primary treatment. The aim of this study is to determine the effect of RGCT on treatment decisions and on psychosocial health., Methods/design: In this randomized controlled trial, 255 newly diagnosed breast cancer patients with at least a 10% risk of carrying a BRCA gene mutation are being recruited from 12 hospitals in the Netherlands. Participants are randomized in a 2:1 ratio to either a RGCT intervention group (the offer of RGCT directly following diagnosis with tests results available before surgical treatment) or to a usual care control group. The primary behavioral outcome is the uptake of direct bilateral mastectomy or delayed prophylactic contralateral mastectomy. Psychosocial outcomes include cancer risk perception, cancer-related worry and distress, health-related quality of life, decisional satisfaction and the perceived need for and use of additional decisional counseling and psychosocial support. Data are collected via medical chart audits and self-report questionnaires administered prior to randomization, and at 6 month and at 12 month follow-up., Discussion: This trial will provide essential information on the impact of RGCT on the choice of primary surgical treatment among women with breast cancer with an increased risk of hereditary cancer. This study will also provide data on the psychosocial consequences of RGCT and of risk-reducing behavior., Trial Registration: The study is registered at the Netherlands Trial Register (NTR1493) and ClinicalTrials.gov (NCT00783822).

- Abstract
Aim: The study assessed compliance of patients with familial adenomatous polyposis (FAP) with endoscopic surveillance., Method: In this nationwide, cross-sectional study, individuals from FAP families registered with the Netherlands Foundation for the Detection of Hereditary Tumours were invited to complete a questionnaire on endoscopic screening experiences., Results: A total of 328 individuals were eligible for the study of whom 85 were at risk for FAP, 108 had an intact rectum after a colectomy with ileorectal anastomosis (IRA), and 135 had had a pouch following a proctocolectomy with ileoanal anastomosis (IPAA). Based on medical record data, 20% of the at-risk group and 26% of the IRA-group were found to be undercompliant with surveillance advice which was associated significantly with perceived self-efficacy, use of sedatives during surveillance, pain after surveillance and low perceived benefits of surveillance (P < 0.05)., Conclusion: One in five individuals at risk for FAP and one in four with a retained rectum are undercompliant with screening advice. We recommend that sedatives should be patient-tailored for FAP individuals undergoing surveillance and that adequate pain medication be provided after endoscopy., (© 2010 The Authors.

- Abstract
Li Fraumeni Syndrome (LFS) is a hereditary cancer syndrome characterized by a high risk of developing various types of cancer from birth through late adulthood. Clinical benefits of surveillance for LFS are limited. The aim of this study is to investigate which advice for regular surveillance, if any, is given to high risk LFS individuals, adherence to that advice, and any psychological gain or burden derived from surveillance. Fifty-five high risk individuals (proven carriers and those at 50% risk) from families with a p53 germline mutation were invited to participate, of whom 82% completed a self-report questionnaire assessing advice for regular surveillance, compliance, perceived benefits and barriers of screening and LFS-related distress (IES) and worries (CWS). In total, 71% of the high risk family members received advice to undergo regular surveillance for LFS. The majority (78%) reported adherence with the recommended advice. All high risk women aged 25 or older reported having been advised to undergo annual breast cancer surveillance (n = 11), of whom 64% (n = 7) in specific received advice to undergo a mammography. Seventy-eight percent of respondents indicated having received tailored surveillance advice based on family cancer history. The large majority of respondents believed in the value of surveillance to detect tumors at an early stage (90%) and reported that it gave them a sense of control (84%) and security (70%). Despite its limited clinical benefits, the majority of high risk LFS family are advised to undergo, and are adherent to, and report psychological benefit from, regular surveillance programs.

- Abstract
Background: Information on postoperative fertility problems in female patients with familial adenomatous polyposis (FAP) is scarce. Previous studies in FAP or colitis patients almost uniformly describe a reduction in fertility after ileal pouch-anal anastomosis, compared with ileorectal anastomosis., Objective: To describe fertility problems in female FAP patients after colectomy and to investigate the relationship between self-reported fertility problems and the type of operation and other surgery-related factors (eg, comorbid conditions)., Methods: A questionnaire addressing surgery, fertility problems, and desire to have children was sent to a nationwide sample of FAP patients. Medical data were verified in the FAP-registry of the Netherlands Foundation for the Detection of Hereditary Tumors. Differences between women with and without fertility problems were investigated., Results: Of 138 patients, 23 (17%) reported current or past fertility problems. The prevalence of fertility problems was similar among those who had undergone ileorectal anastomosis, ileal pouch-anal anastomosis, and proctocolectomy with ileostomy. None of the other surgery-related factors, nor desmoid tumors or cancer were associated significantly with the development of fertility problems. Patients reporting fertility problems were significantly younger at diagnosis of FAP (mean, 20 vs. 27 years, P < 0.05) and at the time of the first surgical procedure (mean, 22 vs. 28 years, P < 0.05)., Conclusions: The risk of developing postoperative fertility problems is not associated significantly with the type of surgery, indication for surgery, complications, or other comorbid conditions. Postoperative fertility problems are more common among women who had their first surgical procedure at a younger age.

- Abstract
Purpose: Li-Fraumeni syndrome (LFS) is a hereditary cancer syndrome, characterized by a high risk of developing cancer at various sites and ages. To date, limited clinical benefits of genetic testing for LFS have been demonstrated, and there are concerns about the potential adverse psychosocial impact of genetic testing for LFS. In this study, we evaluated the uptake of genetic testing and the psychosocial impact of undergoing or not undergoing a genetic test for LFS., Patients and Methods: In total, 18 families with a p53 germline mutation in the Netherlands were identified. Eligible family members were invited to complete a self-report questionnaire assessing motives for undergoing or not undergoing genetic testing, LFS-related distress and worries, and health-related quality of life., Results: Uptake of presymptomatic testing was 55% (65 of 119). Of the total group, 23% reported clinically relevant levels of LFS-related distress. Carriers were not significantly more distressed than noncarriers or than those with a 50% risk who did not undergo genetic testing. Those with a lack of social support were more prone to report clinically relevant levels of distress (odds ratio, 1.3; 95% CI, 1.0 to 1.5)., Conclusion: Although preventive and treatment options for LFS are limited, more than half of the family members from known LFS families choose to undergo presymptomatic testing. An unfavorable genetic test result, in general, does not cause adverse psychological effects. Nonetheless, it is important to note that a substantial proportion of individuals, irrespective of their carrier status, exhibit clinically relevant levels of distress which warrant psychological support.

- Abstract
Von Hippel-Lindau disease (VHL) is a hereditary tumor susceptibility syndrome, characterized by an increased risk of developing multiple benign and malignant tumors at various sites and ages with limited preventive options. This study evaluates the prevalence of distress among VHL family members and factors associated significantly with such distress. Forty-eight families with a VHL mutation were identified via the nine family cancer clinics in the Netherlands. In total, 171 family members (carriers, 50% at-risk, non-carriers) were approached, of whom 123 (72%) completed a self-report questionnaire. Approximately 40% of the VHL family members reported clinically relevant levels of distress, approaching 50% among the carriers and, possibly even more striking, 36% among the non-carriers. Having lost a first degree relative due to VHL during adolescence (OR 11.2; 95% CI 1.4-86.9) was related significantly to heightened levels of distress. Approximately, only one-third of those who reported heightened levels of distress had received professional psychosocial support. A substantial percentage of family members experience clinically relevant levels of distress. We would recommend the introduction of a procedure for screening for distress in this vulnerable population. Special attention should be paid to those individuals who have lost a close relative due to VHL during adolescence.

- Abstract
Objective: Familial adenomatous polyposis (FAP) is characterized by multiple adenomas in the colorectum with a high risk to develop colorectal cancer. It is unclear whether individuals at risk of FAP experience distress due to this potentially life-threatening disease. This nationwide study assessed: (1) the prevalence of psychological distress; and (2) the need for and use of specialized professional psychosocial support., Methods: In this cross-sectional study, all individuals from families at high risk for FAP registered at the Netherlands Foundation for the Detection of Hereditary Tumours were invited to complete a questionnaire assessing, among other issues, generalized, cancer-specific and FAP-specific distress., Results: In total, 525 individuals completed the questionnaire. Approximately 20% of the respondents had moderate to severe levels of FAP-specific distress. Levels of generalized distress were comparable to the general Dutch population. Significantly more individuals with a FAP diagnosis had frequent cancer worries than those at risk of FAP or non-carriers (p=0.02). Distress levels were more strongly associated with psychosocial variables (e.g. perceived cancer risk), than with sociodemographic or clinical variables. Up to 43% of the variance in distress could be explained by all variables combined. Of those moderately to severely distressed, 26% had received specialized professional psychosocial support, while 30% of those did not receive the support they wanted., Conclusions: A substantial minority of individuals reported moderate to severe distress levels associated with FAP. However, only one-third of those received specialized professional psychosocial support. We recommend the use of a screening questionnaire to identify individuals in need of such support.

- Abstract
Childhood DNA testing, prenatal diagnosis (PND) and preimplantation genetic diagnosis (PGD) are available for familial adenomatous polyposis (FAP). However, the use of PND and PGD is controversial. The purpose of this study was to investigate attitudes toward, and experiences with, childhood DNA testing, PND and PGD among members of families at high risk for FAP. In this nationwide, cross-sectional study, questionnaires were sent to individuals from families at high risk for FAP assessing attitudes toward and experiences with childhood testing, PND and PGD, as well as several sociodemographic, clinical and psychosocial variables. Of the individuals from FAP families invited to participate in the study, 525 members participated (response rate=64%). Most parents who had children who were minors (n=93) (82%) were satisfied with the DNA testing procedure. One-third of all individuals wanted DNA testing for their children before age 12. Forty percent of FAP patients indicated that the disease influenced their desire to have children. Only 15% considered termination of pregnancy for FAP acceptable. Approximately 30% of individuals with a FAP diagnosis and their partners considered PND and PGD as acceptable for themselves. A positive attitude was associated with higher levels of guilt and a positive attitude toward termination of pregnancy. Importantly, of those with FAP at childbearing age, 84% had had no previous information at all about either PND or PGD. Future efforts should be aimed at educating FAP family members about reproductive options, allowing them to make an informed choice about family planning. Routine discussion of all reproductive options with a medical specialist should be encouraged.

- Abstract
Background: Women at increased (genetic) risk of breast cancer have to weigh the personal pros and cons of prophylactic mastectomy (PM) as an option to reduce their cancer risk. So far, no routine referral to a psychologist has been investigated for women considering PM. Aim of this study was to asses: 1) the acceptance of the offer of a standard psychological consultation as part of pre-surgical decision-making in high-risk women, 2) reasons for PM and reasons for postponing it, 3) the need for additional psychological interventions, and factors associated, and 4) the frequency of psychiatric/psychological treatment history., Methods: During a 30 months period, women at high risk considering PM were offered a psychological consultation. The content of these, and follow-up, consultations were analyzed., Results: Most women (70 out of 73) accepted the psychological consultation, and 81% proceeded with PM. Main reasons for undergoing PM were to reduce anxiety about cancer, and to reduce the cancer risk. Uncertainty about surgery and the need for further information were the reasons given most frequently for postponing PM. Additional psychological support was given to 31% before and 14% after PM. The uptake of additional support was significantly higher in women with a BRCA1/2 mutation. A history of psychiatric/psychological treatment was present in 36%, mainly consisting of depression and grief after death of a mother., Conclusion: The uptake-rate of the standard psychological consultation indicates a high level of acceptability of this service for women deciding about PM. Since anxiety is one of the main reasons for considering PM, and depression and grief were present in a third, a standard consultation with a psychologist for high-risk women considering PM may be indicated. This may help them arrive at an informed decision, to detect and manage psychological distress, and to plan psychological support services.

- Abstract
Objectives: Familial adenomatous polyposis (FAP) is characterized by the development of multiple adenomas in the colon that can lead to colorectal cancer. Being a carrier for FAP is hypothesized to have a negative impact on psychosocial well-being. This paper reviews the current literature on the psychosocial aspects of FAP., Methods: Four literature databases were used to identify all papers published between 1986 and 2007 about psychosocial and behavioral issues in FAP related to genetic testing. The following topics were reviewed: uptake and psychosocial impact of genetic testing, endoscopic screening behavior and psychosocial well-being in general., Results: Seventeen papers were identified. Across studies, genetic test uptake varied between 62 and 97%. Two out of three studies showed clinical levels of anxiety and/or depression after genetic testing. A minority of individuals were not reassured by a negative test result, and intended to continue endoscopic surveillance. Well-being (e.g. quality of life, family functioning) was found to be lower in some studies, while comparable to the general population in other studies. The studies had several shortcomings, such as mixed patient population (e.g. colorectal and breast cancer) and small sample sizes, and provided no information on other potentially important issues, such as psychosexual development., Conclusions: Future studies should employ larger sample sizes and standardized measurements. Additionally, future studies should address the long-term consequences of genetic testing for FAP, psychosexual development and consequences of FAP for the family as a whole.

- Abstract
Consistent scientific evidence on the possible relationship between psychologic variables and breast cancer development is lacking. In 1996, our group first reported on the present prospective, longitudinal study. We found a weak association between a high score on the antiemotionality scale (indicating an absence of emotional behavior or a lack of trust in one's own feelings) and the development of breast cancer. No associations were found between any of the other 10 studied personality traits and breast cancer development. However, the study had a relatively short follow-up and did not investigate interaction effects between various personality traits. Therefore, the current follow-up study was conducted with the same cohort, which included the 9705 women who attended a biennial population surveillance program for breast cancer and completed a self-report personality questionnaire between January 1, 1989, and December 31, 1990. Women who developed breast cancer during the period from May 17, 1995, through January 1, 2003, formed the case group (n = 217) and were compared with age-matched women without breast cancer who formed the control group (n = 868) with regard to personality traits and medical risk factors for breast cancer. None of the personality factors were statistically significantly associated with an increased risk of breast cancer, with or without adjusting for the medical risk factors. Also, the occurrence of a combination of various personality traits (eg, a so-called cancer-prone personality) was not related to breast cancer development.

- Abstract
Background: This study examined: (1) levels of cancer-specific distress more than one year after genetic counselling for hereditary nonpolyposis colorectal cancer (HNPCC); (2) associations between sociodemographic, clinical and psychosocial factors and levels of distress; (3) the impact of genetic counselling on family relationships, and (4) social consequences of genetic counselling., Methods: In this cross-sectional study, individuals who had received genetic counselling for HNPCC during 1986-1998 completed a self-report questionnaire by mail., Results: 116 individuals (81% response rate) completed the questionnaire, on average 4 years after the last counselling session. Of all respondents, 6% had clinically significant levels of cancer-specific distress (Impact of Event Scale, IES). Having had contact with a professional psychosocial worker for cancer risk in the past 10 years was significantly associated with higher levels of current cancer specific distress. Only a minority of the counselees reported any adverse effects of genetic counselling on: communication about genetic counselling with their children (9%), family relationships (5%), obtaining life insurance (8%), choice or change of jobs (2%), and obtaining a mortgage (2%)., Conclusion: On average, four years after genetic counselling for HNPCC, only a small minority of counselled individuals reports clinically significant levels of distress, or significant family or social problems.

- Abstract
Purpose: Women with BRCA1/2 gene mutations who have completed their childbearing are strong candidates for risk-reducing prophylactic bilateral salpingo-oophorectomy (PBSO). The aim of the current study was to identify baseline predictors of PBSO versus gynecologic screening (GS) in this group of high-risk women., Patients and Methods: Baseline questionnaires were available from 160 BRCA1/2 carriers who participated in a nationwide, longitudinal, observational study of the psychosocial consequences of prophylactic surgery versus periodic screening. Topics addressed by the questionnaire included generic quality of life, cancer-specific distress, risk perception, knowledge of ovarian cancer, and perceived pros and cons of surgery versus screening. PBSO use during the 12-month period after the first gynecologic consultation was determined on the basis of medical record data., Results: During the 12-month follow-up period, 74% of women had undergone PBSO, and 26% opted for screening. Statistically significant multivariate predictors of PBSO included education, general health perceptions, perceived incurability of ovarian cancer, and perceived benefits of surgery., Conclusion: Women with lower educational levels, with poorer general health perceptions, who view ovarian cancer as an incurable disease, and who believe more strongly in the benefits of surgery are more likely to undergo PBSO. Clinicians should ensure that high-risk women are well informed about the low predictive value of GS techniques and about the lethal threat posed by ovarian cancer because of its limited curability.

- Abstract
Purpose: Preventive health strategies for women at increased hereditary risk of ovarian cancer include gynecologic screening (GS) and/or prophylactic oophorectomy (PBSO). Hormone replacement therapy (HRT) is often prescribed to compensate for postsurgical endocrine deficiencies. This study examined the impact of HRT use on levels of endocrine symptoms and sexual functioning among premenopausal women who have undergone PBSO. Comparisons were made with similar women undergoing GS., Patients and Methods: Questionnaire data on endocrine symptoms and sexual functioning were obtained from 450 premenopausal, high-risk women who had participated in this nationwide, cross-sectional, observational study., Results: Thirty-six percent of women had undergone PBSO and 64% had opted for GS. In the PBSO group, 47% of the women were current HRT users. They reported significantly fewer vasomotor symptoms than nonusers (P < .05). However, compared with premenopausal women undergoing GS, oophorectomized HRT users were more likely to report vasomotor symptoms (P < .01). HRT users and nonusers reported comparable levels of sexual functioning. Compared with women in the GS group, oophorectomized HRT users reported significantly more sexual discomfort due to vaginal dryness and dyspareunia (P < .01)., Conclusion: Although HRT has a positive impact on surgically induced vasomotor symptoms, it may be less effective than is often assumed. Symptom levels remain well above those of premenopausal women undergoing screening, and sexual discomfort is not alleviated by HRT. Physicians need to provide younger high-risk women considering PBSO with realistic information about both benefits and drawbacks of this preventive strategy, including information about premature menopause and HRT.

- Abstract
Background and Aims: Periodic colonoscopy is an effective means of reducing the incidence and mortality of colorectal cancer in individuals with a family history of the disease. The aims of this study were to determine the degree of compliance and to identify the factors related significantly to noncompliance with periodic screening in this high-risk population., Methods: A total of 178 individuals who had undergone genetic counseling for colorectal cancer between 1986 and 1998 and who had been advised to undergo periodic screening because of familial colorectal cancer (FCRC) or hereditary nonpolyposis colorectal cancer (HNPCC) were invited to complete a self-report questionnaire on psychosocial issues and screening experiences. Compliance data were derived from medical records and via self-report., Results: A total of 149 individuals (84%) participated in the study. Noncompliance with screening advice was rare (in 3% of cases), but significant delays (more than 1 year) in undergoing screening were observed in approximately 25% of the cases. The number of perceived barriers to screening (eg, discomfort, embarrassment) was the only variable related significantly to noncompliance/screening delay (odds ratio, 1.2; 95% confidence interval, 1.1-1.3). Use of sedatives during the procedure and receipt of a reminder letter seemed to facilitate better compliance., Conclusions: Although few high-risk individuals abstain from screening entirely, approximately one in 4 deviates significantly from the recommended frequency of screening. Increased compliance may be achieved by reducing the discomfort and embarrassment associated with the procedure and by the use of reminder letters.

- Abstract
Diagnostic tests are now available that allow genetic testing for several types of cancer. The aim of genetic counseling and testing for cancer is to educate individuals about cancer risk and cancer prevention, which it is hoped will lead to a reduction in morbidity and mortality. However, at this relatively early stage in the development of genetic counseling and testing programs, information is needed on the psychosocial impact of such programs on both the individual counselee and his/her family. This paper reviews the findings obtained during the past decade on the uptake of genetic testing, reasons for undergoing genetic testing, and the impact of genetic counseling and testing on feelings of distress and guilt. Specific attention is paid to experiences with prophylactic mastectomy and oophorectomy and the effectiveness of the uptake of and satisfaction with these risk-reducing procedures. In addition, the possible impact of genetic testing on insurance, work and future plans is discussed. Suggestions are given for translating research findings into psychosocial services and future research efforts.

- Abstract
The present survey was undertaken to obtain a better understanding of the organisation of standard psychosocial services at the family cancer clinics in The Netherlands. Colleagues at the nine family cancer clinics in The Netherlands completed a brief questionnaire. It was found that all clinics offered professional psychosocial support for asymptomatic women from hereditary breast-ovarian cancer (HBOC) families. On average, one half-time psychosocial worker (usually a social worker and/or a psychologist) was involved in the genetic counselling. All clinics have developed education material about HBOC independently. As a result of the survey, an effort is made to coordinate the development of education material. Furthermore, it is concluded that more attention should be paid to symptomatic mutation carriers and those individuals, who receive inconclusive genetic test results. These subgroups are usually excluded from the protocols for psychosocial care in genetic counselling.

- Abstract
The present prospective study aimed at (1) investigating the frequency of high levels of psychological distress in women with early-stage breast cancer almost two years after diagnosis and (2) identifying characteristics associated with long-term distress. One hundred and seventy women participated on two occasions. Two months after surgery, patients completed questionnaires measuring psychosocial variables (e.g., stressful life-events, health complaints, sleep problems, social support, subjective distress, personality factors), demographic and biomedical variables (e.g., TNM status, type of surgery). At the second measurement, subjective distress was assessed for a second time by means of the Impact of Events Scale (IES). Almost two years after diagnosis, 16% of the women reported a high level of psychological distress as measured by the Intrusion scale (IES). Best predictors of a high level of distress were: intrusive thoughts about the disease, trait-anxiety, health complaints and problems with sleeping. No significant association was found between previous life-events, social support or biomedical variables and levels of distress.

- Abstract
Breast cancer is the most frequently occurring type of cancer in women in the western world. The etiology of a large proportion of breast cancers is still unexplained, and the possibility that psychosocial factors could play a role is not ruled out. Already in pre-Christian times, it was assumed that psychological factors might play a significant role in the development of breast cancer. However, studies have failed to produce conclusive results. There is still a lack of knowledge on the relationship between breast cancer development and psychosocial factors such as stressful life events, coping styles, depression, and the ability to express emotions. The results of this review show that there is not enough evidence that psychosocial factors like 'ways of coping' or 'non-expression of negative emotions', play a significant role in the etiology of breast cancer.
