- Abstract
Introduction: Sub-Saharan Africa (SSA) is plagued by myriads of diseases, mostly infectious; but cancer disease burden is rising among non-communicable diseases. Nigeria has a high burden of cancer, however its remote underserved culturally-conserved populations have been understudied, a gap this study sought to fill., Methods: This was a cross-sectional multi-institutional descriptive study of histologically diagnosed cancers over a four-year period (January 2019-December 2022) archived in the Departments of Pathology and Cancer Registries of six tertiary hospitals in the northeast of Nigeria. Data obtained included age at diagnosis, gender, tumor site and available cancer care infrastructure. Population data of the study region and its demographics was obtained from the National Population Commission and used to calculate incident rates for the population studied., Results: A total of 4,681 incident cancer cases from 2,770 females and 1,911 males were identified. The median age at diagnosis for females was 45 years (range 1-95yrs), and 56 years (range 1-99yrs) for males. Observed age-specific incidence rates (ASR) increased steadily for both genders reaching peaks in the age group 80 years and above with the highest ASR seen among males (321/100,000 persons) compared to females (215.5/100,000 persons). Breast, cervical, prostatic, colorectal and skin cancers were the five most common incident cancers. In females, breast, cervical, skin, ovarian and colorectal cancers were the top five malignancies; while prostate, haematolymphoid, skin, colorectal and urinary bladder cancers predominated in men., Conclusion: Remote SSA communities are witnessing rising cancer disease burden. Proactive control programs inclusive of advocacy, vaccination, screening, and improved diagnostics are needed., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. The author(s) declared that they were an editorial board member of Frontiers, at the time of submission. This had no impact on the peer review process and the final decision., (Copyright © 2024 Ezenkwa, Lawan, Garbati, Suleiman, Katagum, Kabir, Adamu, Modu, Olanrewaju, Dachi, Abdullahi, Alkali, Bojude, Usman, Omotoso, Schlumbrecht, George and Audu.)

- Abstract
Background: The devastating scourge of cervical cancer in Africa is largely due to the absence of preventive interventions, driven by low awareness and poor perception of the disease in the continent. This work is a preliminary effort toward understanding key social drivers promoting this disease in our immediate environment with a view to mitigating it., Method: Female students of two tertiary health institutions in Azare, northeastern Nigeria, were approached to participate in this cross-sectional descriptive study. A structured self-administered questionnaire was administered to consenting participants and covered questions on their socio-demographics, awareness, perception, and attitude about/toward cervical cancer and its prevention. The responses were scrutinized for coherency and categorized into themes using summary statistics, while a chi-square test was used to determine the association between awareness of cervical cancer and participant age, marital status, religion, screening uptake, and willingness to undergo screen., Results: Awareness of cervical cancer was recorded among 174/230 (75.7%) respondents who enrolled in this study; 117 (67.2%) knew that it was preventable, but only three (1.3%) respondents had undergone screening. Among the aware participants, 91 (52.3%) and 131 (75.3%) knew that sexual intercourse and multiple sexual partners are risk factors for the disease, respectively. In contrast, knowledge of the etiology was poor; 82 (47.1%) respondents who knew it was preventable had heard about human papillomavirus (HPV), while 72 (41.4%) knew that HPV causes cervical cancer. Most (78%) of the participants expressed willingness to take a human papillomavirus vaccine or undergo screening (84.6%) if made available to them. Awareness was significantly associated with participants' age (p = 0.022) and willingness to undergo screening (p = 0.016)., Conclusion: This study revealed discordance between awareness and knowledge about cervical cancer. Educational initiatives reflective of population perception/knowledge of cervical cancer are needed to mitigate the rising incidence of this disease, especially among female healthcare providers., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Muhammad, Ezenkwa, Imoudu, Katagum, Usman, George, Schlumbrecht and Audu.)

- Abstract
Context.—: There is limited literature describing gynecologic adenocarcinomas involving the urinary bladder and potential diagnostic pitfalls., Objective.—: To describe key features distinguishing metastatic (or extension of) gynecologic adenocarcinomas from urothelial carcinomas with glandular differentiation., Design.—: Retrospective review of surgical pathology cases of gynecologic adenocarcinomas involving the bladder from 2 different institutions, retrieved from surgical pathology archives, was performed. Morphologic features were recorded, along with immunohistochemistry results when available. Electronic medical records were reviewed for clinical and radiographic information., Results.—: Sixteen cases of gynecologic adenocarcinomas (9 endometrial endometrioid adenocarcinomas, 4 endometrial serous carcinomas, 2 high-grade tubo-ovarian serous carcinomas, and 1 cervical adenosquamous carcinoma) involving the bladder were identified. All included cases had mucosal involvement potentially mimicking primary bladder neoplasms, including 4 cases originally diagnosed as urinary carcinomas. Tumors expressed keratin 7 (12 of 13; 92%), PAX8 (11 of 12; 92%), estrogen receptor (11 of 15; 73%), p16 (8 of 11; 73%), progesterone receptor (8 of 14; 57%), GATA3 (5 of 12; 42%), and p63 (3 of 11; 27%); all tumors were negative for keratin 20 (0 of 12). Features supportive of Müllerian origin included prior history of gynecologic malignancy, lack of morphologic heterogeneity in nonendometrioid tumors, and immunophenotypic coexpression of PAX8 and estrogen receptor with absent GATA3. Potential pitfalls seen in a subset of cases included misleading radiologic and cystoscopic findings, replacement of the overlying urothelial mucosa by tumor mimicking precursor lesions, focal GATA3 and/or p63 positivity, and areas of squamous differentiation in tumors of endometrioid histology., Conclusions.—: A combination of clinical history, certain morphologic features, and proper selection of immunohistochemical stains is key for the correct diagnosis of secondary gynecologic adenocarcinomas involving the urinary bladder., Competing Interests: The authors have no relevant financial interest in the products or companies described in this article., (© 2024 College of American Pathologists.)

- Abstract
Importance: Patients with cancer experience multiple supportive care needs (eg, coping and financial counseling) that, if not addressed, may result in poor clinical outcomes. Limited work has assessed the factors associated with unmet needs in large and diverse samples of ambulatory oncology patients., Objective: To characterize the factors associated with unmet supportive care needs among ambulatory oncology patients and to assess whether such needs were associated with emergency department (ED) visits and hospitalizations., Design, Setting, and Participants: Between October 1, 2019, and June 30, 2022, cross-sectional retrospective analyses were performed in a large and diverse ambulatory cancer population via My Wellness Check, an electronic health record (EHR)-based supportive care needs and patient-reported outcomes (PROs) screening and referral program., Main Outcomes and Measures: Demographic characteristics, clinical characteristics, and clinical outcomes were extracted from EHRs. Data on PROs (ie, anxiety, depression, fatigue, pain, and physical function), health-related quality of life (HRQOL), and supportive care needs were also collected. Logistic regressions examined factors associated with unmet needs. Cumulative incidence of ED visits and hospitalizations were assessed by Cox proportional hazards regression models adjusting for covariates., Results: The 5236 patients in the study had a mean (SD) age of 62.6 (13.1) years and included 2949 women (56.3%), 2506 Hispanic or Latino patients (47.9%), and 4618 White patients (88.2%); 1370 patients (26.2%) indicated Spanish as their preferred language, according to their EHR. A total of 940 patients (18.0%) reported 1 or more unmet needs. Black race (adjusted odds ratio [AOR], 1.97 [95% CI, 1.49-2.60]), Hispanic ethnicity (AOR, 1.31 [95% CI, 1.10-1.55]), 1 to 5 years after diagnosis (AOR, 0.64 [95% CI, 0.54-0.77]), more than 5 years after diagnosis (AOR, 0.60 [95% CI, 0.48-0.76]), anxiety (AOR, 2.25 [95% CI, 1.71-2.95]), depression (AOR, 2.07 [95% CI, 1.58-2.70]), poor physical function (AOR, 1.38 [95% CI, 1.07-1.79]), and low HRQOL scores (AOR, 1.89 [95% CI, 1.50-2.39]) were associated with greater unmet needs. Patients with unmet needs had a significantly higher risk of ED visits (adjusted hazard ratio [AHR], 1.45 [95% CI, 1.20-1.74]) and hospitalizations (AHR, 1.36 [95% CI, 1.13-1.63]) relative to patients without unmet needs., Conclusions and Relevance: In this cohort study of ambulatory oncology patients, unmet supportive care needs were associated with worse clinical outcomes. Patients from racial and ethnic minority groups and those with greater emotional or physical burden were more likely to have 1 or more unmet needs. Results suggest that addressing unmet supportive care needs may be crucial for improving clinical outcomes, and targeted efforts should focus on specific populations.

- Abstract
Approximately 80% of breast cancers are estrogen receptor-positive (ER+), and 68-80% of those occur in premenopausal or perimenopausal women. Since the introduction of tamoxifen for adjuvant endocrine therapy in women with non-metastatic ER+ breast cancer, subsequent trials have demonstrated an oncologic benefit with the addition of ovarian function suppression (OFS) to adjuvant endocrine therapy. Subsequently, therapies to either suppress or ablate ovarian function may be included in the treatment plan for patients that remain premenopausal or perimenopausal after upfront or adjuvant chemotherapy and primary surgery. One strategy for OFS, bilateral salpingo-oophorectomy (BSO), has lasting implications, and the routine recommendation for this strategy warrants a critical analysis in this population. The following is a narrative review of the utility of ovarian suppression or ablation (through either bilateral oophorectomy or radiation) in the context of adjuvant endocrine therapy, including selective estrogen receptor modulators (SERMs) and aromatase inhibitors (AIs). The long-term sequelae of bilateral oophorectomy include cardiovascular and bone density morbidity along with sexual dysfunction, negatively impacting overall quality of life. As gynecologists are the providers consulted to perform bilateral oophorectomies in this population, careful consideration of each patient's oncologic prognosis, cardiovascular risk, and psychosocial factors should be included in the preoperative assessment to assist in shared decision-making and prevent the lifelong adverse effects that may result from overtreatment.

- Abstract
Endometrial cancer is the most common gynecologic cancer in the United States. Over the last several decades, the incidence of aggressive tumors, and thus the rate of death from disease, has increased significantly. The population most affected by these epidemiologic shifts are Black women. Symptom awareness, lack of treatment access, and failure of providers to provide guideline-concordant care are just some of the drivers behind these changes. Race as a social construct has historically categorized women into groups that are not reflective of the nuanced personalization that is required for cancer prevention strategies and targeted cancer treatments. There is, however, an increasing understanding that disaggregation by place of birth and social context are important to understand care-seeking behaviors, genetic drivers of disease, and factors that lead to deleterious outcomes. In this review, we will focus on specific individual-level influences that impact disease diagnosis and care-seeking among Black women, recognizing that the global disparities which exist in this disease encompass multiple domains. Such considerations are crucial to understanding drivers of self-efficacy and to develop programs for knowledge awareness and empowerment within a framework that is both useful and acceptable to these diverse communities at risk.

- Abstract
Besides BRCA1 and BRCA2 , several other inheritable mutations have been identified that increase ovarian cancer risk. Surgical excision of the fallopian tubes and ovaries reduces ovarian cancer risk, but for some non- BRCA hereditary ovarian cancer mutations the benefit of this intervention is unclear. The fallopian tubes of women with hereditary ovarian cancer mutations provide many insights into the early events of carcinogenesis and process of malignant transformation. Here we review cancer pathogenesis in hereditary cases of ovarian cancer, the occurrence of pre-invasive lesions and occult carcinoma in mutation carriers and their clinical management.

- Abstract
Objective: Ovarian cancer in Black women is common in many West African countries but is relatively rare in North America. Black women have worse survival outcomes when compared to White women. Ovarian cancer histotype, diagnosis, and age at presentation are known prognostic factors for outcome. We sought to conduct a preliminary comparative assessment of these factors across the African diaspora., Methods: Patients diagnosed with ovarian cancer (all histologies) between June 2016-December 2019 in Departments of Pathology at 25 participating sites in Nigeria were identified. Comparative population-based data, inclusive of Caribbean-born Blacks (CBB) and US-born Blacks (USB), were additionally captured from the International Agency for Research on Cancer and Florida Cancer Data Systems. Histology, country of birth, and age at diagnosis data were collected and evaluated across the three subgroups: USB, CBB and Nigerians. Statistical analyses were done using chi-square and student's t-test with significance set at p<0.05., Results: Nigerians had the highest proportion of germ cell tumor (GCT, 11.5%) and sex-cord stromal (SCST, 16.2%) ovarian cancers relative to CBB and USB (p=0.001). CBB (79.4%) and USB (77.3%) women were diagnosed with a larger proportion of serous ovarian cancer than Nigerians (60.4%) (p<0.0001). Nigerians were diagnosed with epithelial ovarian cancers at the youngest age (51.7± 12.8 years) relative to USB (58.9 ± 15.0) and CBB (59.0± 13.0,p<0.001). Black women [CBB (25.2 ± 15.0), Nigerians (29.5 ± 15.1), and USB (33.9 ± 17.9)] were diagnosed with GCT younger than White women (35.4 ± 20.5, p=0.011). Black women [Nigerians (47.5 ± 15.9), USB (50.9 ± 18.3) and CBB (50.9 ± 18.3)] were also diagnosed with SCST younger than White women (55.6 ± 16.5, p<0.01)., Conclusion: There is significant variation in age of diagnosis and distribution of ovarian cancer histotype/diagnosis across the African diaspora. The etiology of these findings requires further investigation., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 George, Omotoso, Pinto, Mustapha, Sanchez-Covarrubias, Umar, Umar, Oluwasola, Okolo, Anthony, Ukekwe, Bakari, Dahiru, Abdullahi, Abimiku, Abdurrahman, Usman, Ahmed, Usman, Kabir, Eleje, Chiemeka, Nzeribe, Nweke, Kadas, Suleiman, Ekanem, Uche, Paul, Agwu, Edegbe, Anorlu, Banjo, Ajenifuja, Fawole, Kazeem, Magaji, Silas, Athanasius, Tamunomie, Bassey, Abudu, Ango, Abdullahi, Lawal, Kabir, Ekanem, Ezeanochie, Yahaya, Castillo, Bahall, Chatrani, Brambury, Bowe, Halliday, Bruney, Butler, Ragin, Odedina, Chamala, Schlumbrecht and Audu.)

- Abstract
Purpose: Understanding the distribution of human papilloma virus (HPV) subtypes in limited-resource settings is imperative for cancer prevention strategies in these regions. The objective of our study is to compare the prevalence of cervical HPV genotypes in women across the African diaspora., Methods: This study was approved by the African Caribbean Consortium (AC3). Six member institutions (Benin, Ethiopia, The Bahamas, Tobago, Curacao, and Jamaica) provided independently collected HPV data. Prevalence comparisons across for each nation were performed followed by an assessment of anticipated 9-valent vaccine coverage. Chi-square or Fisher's exact tests were used with significance at P < .05., Results: One thousand three hundred fifty high-risk (HR) and 584 low-risk (LR) HPV subtypes were identified in the entire cohort. The most common HR HPV subtype was HPV 16 (17.9%) of infections. The distribution of HR and LR subtypes varied by country. The proportion of HR-HPV subtypes covered by the current 9-valent vaccine was lower in African countries compared with the Caribbean countries (47.9% v 67.9%; P < .01). No significant difference was seen for LR subtypes (8.1% African continent v 5.2% Caribbean; P = .20). Marked variation in the proportion of infections covered by the 9-valent vaccine persisted in individual countries., Conclusion: Significant variations in HPV prevalence were identified among African and Afro-Caribbean women. A large number of women in these regions are potentially uncovered by current vaccination formulation, particularly low-risk HPV infections., Competing Interests: Matthew SchlumbrechtConsulting or Advisory Role: TesaroNo other potential conflicts of interest were reported.

- Abstract
Lynch Syndrome (LS) prevalence in underrepresented minorities are lacking. The objective of this study was to assess the prevalence of LS in a minority patient population. Secondary objectives included identifying factors associated with successful LS screening and to characterize clinicopathologic features. Women with endometrial cancer treated within a university system from 2014 and 2016 were included. Immunohistochemistry (IHC) results of MLH1, PMS2, MSH2 and MSH6 were obtained from medical records and clinicopathologic factors abstracted. Patients not previously screened for LS were screened. 276 patients were evaluable. More minority women were screened as part of their routine cancer care (p = 0.005). Additionally, women 50 years or younger were more likely to be screened for LS compared to women older than 51(p = 0.009) and uninsured or reliant on Medicaid patients (p = 0.011) were more likely to be screened during routine care. Six patients received confirmatory germline testing for LS (4.3%), and another 8 patients had a staining pattern suggestive of LS. In an underrepresented population, the rate of LS in endometrial cancer is similar to previous reports. LS may be under diagnosed and opportunities missed when universal screening is not applied in minority women.

Rezk A, Richards S, Patricia Castillo R, and Schlumbrecht M
- Abstract
Anastomosing hemangioma (AH) is an uncommon benign vascular tumor reported to occur in the kidney and, in rare instances, the ovary. While most cases of AH in the ovary are incidental findings, we report a case of ovarian AH presenting with abdominal ascites and elevated CA-125 suggestive of metastatic ovarian cancer. Postoperative histopathologic examination demonstrated a tumor consisting of numerous vascular spaces lined by benign-appearing endothelial cells with exuberant hilus cell hyperplasia. These characteristics led to the diagnosis of anastomosing hemangioma of the ovary. A summary of the characteristics of AH, along with a review of all previously reported cases and possible theories for its presentation, are discussed., Competing Interests: The patient has provided consent for this manuscript.

- Abstract
Thrombocytosis (platelets ≥ 400K) is a common hematologic finding in gynecologic malignancies and associated with worse outcomes. Limited data exist on the prognostic capability of thrombocytosis in women with high-grade endometrial cancer (EC). Our objective was to describe the associations between elevated platelets at diagnosis, clinicopathologic features, and survival outcomes among women with high-grade, non-endometrioid EC. A review of the institutional cancer registry was performed to identify these women treated between 2005 and 2017. Sociodemographic, clinical, and outcomes data were collected. Analyses were performed using chi-square tests, Cox proportional hazards models, and the Kaplan-Meier method. A total of 271 women were included in the analysis. A total of 19.3% of women had thrombocytosis at diagnosis. Thrombocytosis was associated with reduced median overall survival (OS) compared with those not displaying thrombocytosis (29.4 months vs. 60 months, p < 0.01). This finding was most pronounced in uterine serous carcinoma (16.4 months with thrombocytosis vs. 34.4 months without, p < 0.01). While non-White women had shorter median OS for the whole cohort in the setting of thrombocytosis (29.4 months vs. 39.6 months, p < 0.01), among those with uterine serous carcinoma (USC), this finding was reversed, with decreased median OS in White women (22.1 vs. 16.4 months, p = 0.01). Thrombocytosis is concluded to have negative associations with OS and patient race.

- Abstract
Low-grade serous ovarian carcinoma (LGSOC) is known to exhibit chemoresistance. Effective treatment options for recurrent disease are few and often limited to hormone antagonism. Combination of endocrine therapies with MEK-inhibitors displays synergism in preclinical ovarian cancer models, however. This brief communication presents the use of combination anti-estrogenic and MEK-inhibitor therapies, fulvestrant and trametinib, as treatment in a heavily pretreated patient with estrogen receptor-positive, recurrent LGSOC. The dual-therapy regimen was well tolerated and appeared to confer 9 months of progression-free survival. Further investigation is warranted to explore this effect., (© AlphaMed Press 2020.)

- Abstract
Background: Caribbean immigrants represent one of the largest groups of minorities in the United States (US), yet are understudied. Racial and ethnic disparities among women with ovarian cancer have been reported, but not in immigrant populations. Our objective was to evaluate differences in the clinicopathologic features and survival outcomes of Caribbean-born (CB) immigrants with ovarian cancer, with special focus on the influence of race and ethnicity on these measures. Methods: A review of the institutional cancer registry was performed to identify women with known nativity treated for epithelial ovarian cancer between 2005 and 2017. Sociodemographic, clinical, and outcomes data were collected. Analyses were done using chi-square, Cox proportional hazards models, and the Kaplan-Meier method, with significance set at p < 0.05. Results: 529 women were included in the analysis, 248 CB and 281 US-born (USB). CB women were more likely to have residual disease after debulking surgery (31.2 vs. 16.8%, p = 0.009) and be treated at a public facility (62.5 vs. 33.5%, p < 0.001). Black CB women less frequently received chemotherapy compared to White CB women (55.2 vs. 82.2%, p = 0.001). Among all CB women, Hispanic ethnicity was independently associated with improved survival when adjusting for other factors (HR 0.61 [95% CI 0.39-0.95], p = 0.03). White Hispanic CB women had a median overall survival (OS) of 59 months while Black, non-Hispanic CB women had a median OS of 24 months (log-rank p = 0.04). Conclusion: Among Caribbean-born women with ovarian cancer, Hispanic ethnicity is significantly associated with improved survival outcomes, regardless of race., (Copyright © 2020 Schlumbrecht, Cerbon, Castillo, Jordan, Butler, Pinto and George.)

- Abstract
Epithelial ovarian cancer represents a group of heterogeneous diseases with high grade serous cancer (HGSC) representing the most common histotype. Molecular profiles of precancerous lesions found in the fallopian tube have implicated this tissue as the presumptive site of origin of HGSC. Precancerous lesions are primarily found in the distal fallopian tube (fimbria), near the ovary relative to the proximal tissue (ampulla), nearer to the uterus. The proximity of the fimbria to the ovary and the link between ovulation, through follicular fluid release, and ovarian cancer risk led us to examine transcriptional responses of fallopian tube epithelia (FTE) at the different anatomical sites of the human fallopian tube. Gene expression profiles of matched FTE from the fimbria and from premenopausal women resulted in differentially expressed genes (DEGs): CYYR1, SALL1, FOXP2, TAAR1, AKR1C2/C3/C4, NMBR, ME1 and GSTA2. These genes are part of the antioxidant, stem and inflammation pathways. Comparisons between the luteal phase (post-ovulation) to the follicular phase (pre-ovulation) demonstrated greater differences in DEGs than a comparison between fimbria and fallopian tube anatomical differences alone. This data suggests that cyclical transcriptional changes experienced in pre-menopause are inherent physiological triggers that expose the FTE in the fimbria to cytotoxic stressors. These cyclical exposures induce transcriptional changes reflective of genotoxic and cytotoxic damage to the FTE in the fimbria which are closely related to transcriptional and genomic alterations observed in ovarian cancer.

- Abstract
Background: Black women are known to have a higher risk of aggressive endometrial cancers. Little data exist about the role of nativity as a determinant of survival outcomes in women with this disease., Aim: Our objective was to evaluate a population of Haitian immigrants with endometrial cancer in an urban setting using the Florida Cancer Data System (FCDS)., Methods: A search of FCDS identified 107 women born in Haiti and who received treatment for invasive endometrial cancer in Miami-Dade County between 1989 and 2013. Clinicopathologic data were extracted to describe the cohort and assess associations with overall survival. Statistical analyses were performed using Cox proportional hazards models, the log-rank test, and the Kaplan-Meier method, with significance set at P ≤ 0.05., Results: Median age at diagnosis was 65 years. 63.9% of the patients had a type II, high-grade, histology, and 52.6% presented with extrauterine metastatic disease. Nearly three quarters had health insurance. Within the entire cohort, only presence of extrauterine disease was associated with worse overall survival [Hazard ratio (HR) = 2.70, 95% confidence interval (CI): 1.31-5.57, P = 0.007]. However, after stratification by histologic grade, both age (HR = 0.88, 95%CI: 0.81-0.96, P = 0.002) and extrauterine disease (HR = 2.49, 95%CI: 1.01-6.21, P = 0.049) were independently associated with worse survival, but only in women with type II malignancies., Conclusion: Urban Haitian women with endometrial cancer have a high burden of aggressive histologies. Additional investigation to explain the etiology of these findings is needed., Competing Interests: Conflict-of-interest statement: The authors declare that they have no competing interests., (©The Author(s) 2019.

- Abstract
Objective: Polypharmacy has been associated with morbidity and mortality in patients with cancer. Data about polypharmacy among patients with ovarian cancer are limited. The primary objective of this study was to evaluate polypharmacy in a cohort of patients with ovarian cancer and to assess the evolution of polypharmacy from initial presentation to 2 years posttreatment. A secondary objective was to evaluate differences in polypharmacy between a subset of patients primarily treated in our comprehensive cancer center (CCC) and our safety net hospital (SNH)., Methods: Women treated for ovarian cancer between January 1, 2011, and December 31, 2016, were included. Data were abstracted from the electronic medical record. Medication safety was assessed using the established Anticholinergic Burden (ACB) scale and the Beers criteria. Statistical analyses were performed using paired t tests and Cox proportional hazards models, with significance set at p < .05., Results: The study included 152 patients. The majority of patients had high-grade serous carcinoma. Hypertension was the most common medical problem. The mean number of medications at the time of diagnosis was 3.72. Paired testing demonstrated significant patient-level increases in the number medications at 2 years following initial diagnosis (4.16 vs. 7.01, p < .001). At the CCC, 47.4% of patients met criteria for polypharmacy at diagnosis compared with 19.4% at the SNH ( p < .001). By 2 years postdiagnosis, 77.6% of patients at the CCC met criteria for polypharmacy compared with 43.3% at the SNH ( p = .001). The use of any medications on the ACB scale ( p < .001) increased significantly between initial diagnosis and 2 years for the entire population. Polypharmacy was not a significant predictor of overall survival., Conclusion: Polypharmacy worsens as women go through ovarian cancer treatment. Both at initial presentation and at 2 years postdiagnosis, rates of polypharmacy were higher at the CCC. Polypharmacy did not have an effect on survival in this cohort., Implications for Practice: Awareness of escalating numbers of medications and potentially adverse interactions is crucial among women with ovarian cancer, who are at high risk for polypharmacy., Competing Interests: Disclosures of potential conflicts of interest may be found at the end of this article., (© AlphaMed Press 2019.)

- Abstract
Background: With the growing understanding of the molecular and genetic profiles of cancers, targeted treatments are increasingly utilized in personalized cancer care. The objective of this study was to determine how these advances have translated into practice by examining how often molecular profiling of gynecological tumors led to treatment changes., Methods: We identified women with gynecological cancers at our institution who had molecular tumor testing performed from November 2014 to June 2017. Clinicopathologic data were extracted from medical records. We determined (a) if molecular profiling identified actionable targets for which therapy is available, and (b) whether the patient's treatment course changed as a result of molecular profiling. Chi-square, Wilcoxon rank-sum, and Fisher's exact tests were used with a P < 0.05 considered statistically significant., Results: We identified 152 patients with gynecologic cancers who underwent molecular profiling. Of the 152 patients, 116 (76.3%) had actionable mutations identified, with 41 (35.3%) patients having a treatment change. Stratified by cancer type, molecular profiling most frequently identified an actionable target in patients with endometrial cancer (73.6%). Changes in treatment occurred most frequently in patients with endometrial cancer, 22 (56.4%), and ovarian cancers, 16 (39%), as compared to patients with cervical and vulvar cancer (P = 0.02). Of those patients who received a change in treatment, 39 patients (95.1%) received an FDA-approved therapeutic agent, while two patients (4.8%) were enrolled in a clinical trial., Conclusion: Molecular profiling in gynecologic cancers often identified at least one actionable mutation; however, only in a minority of these cases was the course of treatment changed. Further studies are needed to elucidate optimal timing for testing to best utilize actionable information., (© 2019 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.)

- Abstract
Placenta percreta is increasing in incidence and is associated with the risk of life-threatening haemorrhage. Patients who do not accept blood products present a unique challenge to obstetrician-gynaecologists. In this case report, we present the case of a 42-year-old pregnant Jehovah's Witness with a complete placenta previa and confirmed percreta at 26 weeks' gestation. Due to her religious beliefs against the use of blood products, she was managed with a stepwise surgical approach which involved caesarean delivery with internal iliac (hypogastric) artery ligation, weekly methotrexate and delayed hysterectomy 6 weeks later. Non-traditional, alternative approaches to the management of abnormal placentation in patients declining blood products warrant exploration., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

- Abstract
Purpose: ASCO recommends early involvement of palliative care for patients with advanced cancers on the basis of evidence from 18 randomized trials. We examined racial and ethnic minority representation in these trials and the role of race and ethnicity in the statistical analyses. The goal was to identify specific gaps in the palliative care evidence base for these individuals and potential strategies to address them., Methods: We reviewed the 18 trials cited in the 2012 and 2017 ASCO clinical statements on integrating palliative care into oncology. We extracted data on the reporting and categorization of race and ethnicity, on the enrollment of specific racial and ethnic minority groups, and on how race and ethnicity were addressed in the analyses., Results: One third of patient trials reported representation of specific racial and ethnic minority groups, one third reported rates of "white" versus "other," and one third did not report race or ethnicity data. Among the patient trials with race and ethnicity data, 9.9% of participants were Asian, 8.8% Hispanic/Latino, and 5.7% African American. Analyses that used race and ethnicity were primarily baseline comparisons among randomized groups., Conclusion: Race and ethnicity were inconsistently reported in the trials. Among those that provided race and ethnicity data, representation of specific racial and ethnic minority groups was low. In addition to more research in centers with large minority populations, consistent reporting of race and ethnicity and supplementary data collection from minority patients who participate in trials may be strategies for improvement.

- Abstract
Background: With ongoing healthcare reform and shrinking numbers of oncologists, appropriate triaging of gynecologic cancer survivor care is crucial. Input from patients is a necessary part of this task. The objective of this study was to assess the preferences of gynecologic cancer survivors for surveillance after the completion of treatment., Methods: A 38-item questionnaire was developed and launched in conjunction with the Foundation for Women's Cancer (FWC). All women who registered as gynecologic cancer survivors with the FWC were invited to participate. Patients were asked about physician preferences for multiple symptoms and diagnoses, and when they felt comfortable transferring care out of their oncologists' offices. Analyses were performed with chi-square and logistic regression., Results: Six hundred twenty four patients completed the questionnaire. Sixty six percent had ovarian cancer, and 86% were primarily treated by a gynecologic oncologist. Fifty seven percent of the respondents reported being unwilling to see a physician other than their oncologist for survivorship care at any time. Women age > 60 years were less willing to leave their oncologists for survivorship care at any time compared to younger women (OR 1.53 [95% CI 1.03-2.27], p = 0.03). Ovarian cancer survivors were also more likely to report a desire to stay with their oncologists compared with uterine cancer survivors (p < 0.001). With few exceptions, respondents preferred management of non-oncologic medical problems by their oncologists., Conclusions: Gynecologic cancer survivors prefer that their oncologists remain heavily involved in survivorship care. Reconciling patient needs with physician and financial constraints will be a challenge as the survivor population continues to grow.

- Abstract
Background: Preparation in the business of medicine is reported to be poor across a number of specialties. No data exist about such preparation in gynecologic oncology training programs. Our objectives were to evaluate current time dedicated to these initiatives, report recent graduate perceptions about personal preparedness, and assess areas where improvements in training can occur., Methods: Two separate surveys were created and distributed, one to 183 Society of Gynecologic Oncology candidate members and the other to 48 gynecologic oncology fellowship program directors. Candidate member surveys included questions about perceived preparedness for independent research, teaching, job-hunting, insurance, and billing. Program director surveys assessed current and desired time dedicated to the topics asked concurrently on the candidate survey. Statistical analysis was performed using Chi-squared (or Fisher's exact test if appropriate) and logistic regression., Results: Survey response rates of candidate members and program directors were 28% and 40%, respectively. Candidate members wanted increased training in all measures except retrospective protocol writing. Female candidates wanted more training on writing letters of intent (LOI) ( p = 0.01) and billing ( p < 0.01). Compared to their current schedules, program directors desired more time to teach how to write an investigator initiated trial (p = 0.01). 94% of program directors reported having career goal discussions with their fellows, while only 72% of candidate members reported that this occurred ( p = 0.05)., Conclusion: Recent graduates want more preparation in the non-clinical aspects of their careers. Reconciling program director and fellow desires and increasing communication between the two may serve to achieve the educational goals of each.
