PURPOSE The Groningen International Study on Sentinel nodes in Vulvar cancer (GROINSS-V)-II investigated whether inguinofemoral radiotherapy is a safe alternative to inguinofemoral lymphadenectomy (IFL) in vulvar cancer patients with a metastatic sentinel node (SN). METHODS GROINSS-V-II was a prospective multicenter phase-II single-arm treatment trial, including patients with early-stage vulvar cancer (diameter < 4 cm) without signs of lymph node involvement at imaging, who had primary surgical treatment (local excision with SN biopsy). Where the SN was involved (metastasis of any size), inguinofemoral radiotherapy was given (50 Gy). The primary end point was isolated groin recurrence rate at 24 months. Stopping rules were defined for the occurrence of groin recurrences. RESULTS From December 2005 until October 2016, 1,535 eligible patients were registered. The SN showed metastasis in 322 (21.0%) patients. In June 2010, with 91 SN-positive patients included, the stopping rule was activated because the isolated groin recurrence rate in this group went above our predefined threshold. Among 10 patients with an isolated groin recurrence, nine had SN metastases > 2 mm and/or extracapsular spread. The protocol was amended so that those with SN macrometastases (> 2 mm) underwent standard of care (IFL), whereas patients with SN micrometastases (≤ 2 mm) continued to receive inguinofemoral radiotherapy. Among 160 patients with SN micrometastases, 126 received inguinofemoral radiotherapy, with an ipsilateral isolated groin recurrence rate at 2 years of 1.6%. Among 162 patients with SN macrometastases, the isolated groin recurrence rate at 2 years was 22% in those who underwent radiotherapy, and 6.9% in those who underwent IFL ( P = .011). Treatment-related morbidity after radiotherapy was less frequent compared with IFL. CONCLUSION Inguinofemoral radiotherapy is a safe alternative for IFL in patients with SN micrometastases, with minimal morbidity. For patients with SN macrometastasis, radiotherapy with a total dose of 50 Gy resulted in more isolated groin recurrences compared with IFL.

Objective Improving shared decision‐making (SDM) enables more tailored cancer treatment decisions. We evaluated a Time Out consultation (TOC) with the general practitioner (GP), between cancer diagnosis and treatment decision, which aims at supporting SDM and improving continuity of primary care. This study aims to evaluate the effects of a TOC on perceived SDM, information provision and self‐efficacy. Methods This randomised controlled trial included newly diagnosed patients with curable cancer (breast, lung, colorectal, gynaecologic and melanoma) from four Dutch hospitals. Primary outcome is perceived SDM and secondary outcomes are information provision and self‐efficacy. Results One hundred fifty‐four patients (control n = 77, intervention n = 77) – female: 75%, mean age: 61 (SD ± 11.9). In the intervention group, 80.5% (n = 62) had a TOC, of which 82.3% (n = 51) took place after treatment decision. Perceived SDM was lower in the intervention group (−8.9 [95% CI: 0.6–17.1]). Among those with a TOC before treatment decision (n = 11), perceived SDM was comparable to the control group (66.5 ± 27.2 vs. 67.9 ± 26.1). Conclusion Even though patients are motivated to have a TOC, implementing a TOC between diagnosis and treatment decision is challenging. Effects of a timely TOC could not be established. Non‐timely TOC decreased perceived SDM. Planning of the TOC should be optimised, and future research should establish if adequately timed TOC results in improved SDM in cancer patients.

Objective Cancer patients are increasingly involved in decision‐making for cancer treatment. General practitioners' (GPs) support in this process is advocated. Therefore, GPs need to be aware of patients' treatment decision‐making process and their potential role. We aim to understand the treatment decision‐making process and to explore the added value of GP involvement, from the perspective of cancer patients treated with curative intent. Methods An explorative qualitative study was performed. Semi‐structured interviews were conducted with 20 purposively sampled Dutch cancer patients treated with curative intent. Results Patients' treatment decision‐making process was dominated by a focus on ‘safeguarding survival’. Patients generally followed the treatment plan as proposed by their physician and did not always experience having a treatment choice. The majority of patients expressed added value for GP involvement, mainly to provide psychological support, but also for providing shared decision‐making (SDM) support. Conclusion The treatment decision‐making process of cancer patients treated with curative intent is dominated by the urge to ‘safeguard survival’. GPs should be aware of their added value in providing psychological support and their potential role to support SDM following a cancer diagnosis.

Background: Vulvar Paget disease (VPD) is a rare skin disorder that is considered premalignant.Objective: To assess the clinical course, treatment schedules, and effect of invasion and treatment on recurrence and survival in patients with VPD.Methods: Data on women with VPD were retrieved from the medical files and pathology reports in all Dutch tertiary university medical centers. Disease-free survival and 5-year disease-specific survival were estimated by using Kaplan-Meier curves.Results: Data on 113 patients whose VPD was diagnosed between 1991 and 2016 were analyzed; 77% had noninvasive VPD. Most of the women (65%) underwent a surgical procedure. Recurrences were reported in 40%. Of the women with noninvasive VPD, 8% developed invasion. There were no disease-specific deaths reported in the women with noninvasive VPD. The 5-year disease-specific survival rate was greater than 98% in noninvasive and microinvasive VPD, but significantly worse in invasive VPD (50% [P Limitations: The main limitations of this study are its retrospective character and the fact that original pathology samples were not available for reassessment.Conclusions: VPD is extremely rare, and the recurrence rates are high. Most patients have noninvasive VPD, which does not affect survival and should be considered a chronic disorder with limited invasive potential. In cases of invasive disease, survival decreases significantly.

METHODS: In this prospective, observational study, we recruited 178 premenopausal women with a high risk for ovarian cancer. Fifty-seven women opted for RRSO and 121 for gynaecological screening (GS). Women completed questionnaires before surgery (T1) and 3 (T2) and 9 (T3) months post surgery, or at equivalent time points for the GS-group. Menopausal symptoms were assessed with the Functional Assessment of Cancer Therapy-Endocrine Subscale (FACT-ES) and sexual functioning with the Sexual Activity Questionnaire (SAQ). Groups were compared using repeated measures mixed effect models for continuous variables, and generalised estimating equations for longitudinal ordered categorical data. RESULTS: Twenty-seven women who underwent RRSO used HRT after surgery (HRT-users) and 30 did not (HRT-non-users). There were no significant group differences at baseline on the outcome variables. Compared to the HRT-users, the HRT-non-users exhibited a significant increase in overall endocrine symptoms (p = 0.001, effect size (ES) = -0.40 and p < 0.001, ES = -0.59 at T1 and T2, respectively), and in sexual discomfort (p < 0.001, ES = 0.74 and p < 0.001, ES = 1.17). The effect size provides an indication of the magnitude of the observed group differences. An effect size of 0.50 or greater is generally considered to be clinically relevant. No significant differences over time were observed between the HRT-users and the GS-group on any of the outcomes. CONCLUSION: Our results suggest that HRT use in the first year after RRSO has beneficial effects in terms of minimising endocrine symptoms and sexual symptoms in premenopausal women who have undergone RRSO.

BRCA1/2 germ line mutation carriers have a high risk of developing fallopian tube carcinoma (FTC), thought to occur through different early (p53 signatures) and later (dysplasia, intra-epithelial carcinoma) premalignant stages. Promoter hypermethylation of tumour suppressor genes is known to play a key role in (early) carcinogenesis. However, little is known about methylation in normal and (pre)malignant fallopian tube tissue. We identified 14 areas of p53 accumulation in the fallopian tubes of BRCA mutation carriers. Cells from these areas were harvested together with cells from adjacent benign appearing areas. An age-matched non-BRCA sporadic control group (n=13) and eight sporadic FTCs were included as negative and positive controls respectively. Methylation-specific multiplex ligation-dependent probe amplification was used to assess promoter methylation of 70 tumour suppressor genes in all samples. We observed a gradual increase in methylation from sporadic control tissue (median cumulative methylation index (CMI) 568.19) through normal tissue and from areas of p53 accumulation in BRCA carriers (median CMI 687.54 and 676.72) to FTC (median CMI 780.97). Furthermore, the methylation percentage of many individual tumour suppressor genes differed significantly between these groups, gradually increasing as for CMI. Between areas with and without p53 accumulation in BRCA mutation carriers no significant differences were found. In this paper, we have shown that BRCA mutation carriers display increased methylation of tumour suppressor genes in their non-malignant fallopian tube epithelium, closer to methylation levels in FTC than to normal sporadic tissue. Methylation could, therefore, play an important role in the increased risk of gynaecological malignancies in BRCA mutation carriers.

Contains fulltext : 89256.pdf (Publisher’s version ) (Closed access) BACKGROUND: Currently, all patients with vulvar cancer with a positive sentinel node undergo inguinofemoral lymphadenectomy, irrespective of the size of sentinel-node metastases. Our study aimed to assess the association between size of sentinel-node metastasis and risk of metastases in non-sentinel nodes, and risk of disease-specific survival in early stage vulvar cancer. METHODS: In the GROningen INternational Study on Sentinel nodes in Vulvar cancer (GROINSS-V), sentinel-node detection was done in patients with T1-T2 (

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.

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.
