Take me to your leader: Reporting structures and equity in academic gynecologic oncology.

OBJECTIVE: Gynecologic oncology includes increasing percentages of women. This study characterizes representation of faculty by gender and subspecialty in academic department leadership roles relevant to the specialty. METHODS: The American Association of Medical Colleges accredited schools of medicine were identified. Observational data was obtained through institutional websites in 2019. RESULTS: 144 accredited medical schools contained a department of obstetrics and gynecology with a chair; 101 a gynecologic oncology division with a director; 98 a clinical cancer center with a director. Women were overrepresented in academic faculty roles compared to the US workforce (66 vs 57%, p < 0.01) but underrepresented in all leadership roles (p < 0.01). Departments with women chairs were more likely to have >50% women faculty (90.2 vs 9.8%, p < 0.01); and have larger faculties (80.4 vs 19.6% >20 faculty, p = 0.02). The cancer center director gender did not correlate to departmental characteristics. A surgically focused chair was also associated with >50% women faculty (85.7 vs 68.3%, p = 0.03); faculty size >20 (85.7 vs 61.4%, p < 0.01); and a woman gynecologic oncology division director (57.6 vs 29.4%, p < 0.01; 68.4 vs 31.7%, p < 0.01) and gynecologic oncology fellowship (50 vs 30.4%, p < 0.01; 59.1 vs 32%, p < 0.01). Gynecologic oncology leadership within cancer centers was below expected when incidence and mortality to leadership ratios were examined (p < 0.01, p < 0.01). CONCLUSION: Within academic medical schools, women remain under-represented in obstetrics and gynecology departmental and cancer center leadership. Potential benefits to gynecologic oncology divisions of inclusion women and surgically focused leadership were identified.

The role of menopausal hormone therapy in women with or at risk of ovarian and breast cancers: Misconceptions and current directions.

For women who are candidates for menopausal hormone therapy (MHT), estrogen can provide relief from symptomatic menopause, decrease rates of chronic illnesses, and improve health-related quality of life. However, confusion surrounds the evidence regarding the impact of exogenous estrogen and progesterone on the breast and ovary. Available data regarding the risks of MHT (estrogen and/or progestin) related to the development of breast and ovarian cancer are often inconsistent or incomplete. Modern molecular and genetic techniques have improved our understanding of the heterogeneity of breast and ovarian cancer. This enhanced understanding of the disease has impacted our understanding of carcinogenesis. Treatment options have evolved to be more targeted toward hormonal therapy for certain subtypes of disease, whereas cytotoxic chemotherapy remains the standard for other histological and molecular subtypes. The role of MHT in the breast and ovarian cancer survivor, as well as women who are at high risk for the development of hereditary breast and ovarian cancer, remains controversial despite evidence that this treatment can improve quality of life and survival outcomes. Through this article, we examine the evidence for and against the use of MHT with a focus on women who have or are at high risk for breast and ovarian cancer.

Awareness and acceptability of population-based screening for pathogenic BRCA variants: Do race and ethnicity matter?

OBJECTIVE: To evaluate awareness and acceptability of population-based BRCA testing among an unselected population of women presenting for annual gynecologic health assessment, with secondary objective to determine if a racial disparity exists in acceptability and awareness of this screening strategy. METHODS: Women presenting for routine gynecologic care in an outpatient setting of a single academic institution were anonymously surveyed. Survey collected age, self-identified race and ethnicity, education level, personal and family history of breast and/or ovarian cancer (BOC), awareness and interest, and willingness to pay out of pocket for testing. Responses were compared with bivariate and multivariate analysis. RESULTS: Interest in testing was expressed in 150 of 301 (45.1%) of participants. Women with a family history of BOC were more likely to be interested in testing than those without (OR = 1.9 (1.0-3.6)). Interest in testing was associated willingness to pay (OR = 3.3 (1.7-6.4)). Higher education level was associated with awareness of testing (OR = 9.9 (2.0-49.7)). Interest in testing was similar between racial groups, but awareness and willingness to pay for testing were higher among White women. Multivariate analysis with adjustment for education level confirmed that Black and Hispanic women were less likely to have awareness of genetic testing compared to White women and non-Hispanic Women, respectively (OR = 0.11 (0.05-0.3); OR = 0.10 (0.01-0.8)). CONCLUSIONS: Interest in genetic testing among women in the general population is high. Despite interest, awareness of BRCA is poor among Black and Hispanic women even when adjusting for education level.

Reproductive health care across the lifecourse of the female cancer patient.

Reproductive health is a key component of cancer care and survivorship, encompassing gynecologic issues ranging from contraception and fertility to treatment of sexual dysfunction and menopause. Yet, oncology providers are often unfamiliar with the management of gynecologic issues. In order to address the unmet needs of female cancer patients, reproductive health should be addressed at the time of cancer diagnosis and continue through survivorship. Universal screening for pregnancy intention can guide counseling on contraception and fertility preservation. Safe and efficacious contraceptive options for both patients undergoing active treatment and cancer survivors are available and can often offer non-contraceptive benefits such as regulation of menses. Prompt referral to reproductive endocrinology specialists allows patients to explore options for fertility preservation prior to the receipt of cancer-directed therapies. Due to a rapid drop in hormone levels, treatment-induced menopause often results in severe symptoms. In patients with induced menopause, balancing the risks of hormone therapy compared to the decreased quality of life and health concerns associated with early menopause may help patients with difficult decisions regarding symptom control. Cancer treatment impacts sexual function with both physical changes to the vulvovaginal tissues and altered relationship dynamics. Open discussions on the impact to sexual health are paramount to quality of life after cancer. While more data is needed in many areas, proactive management of reproductive health issues is crucial to quality of life in cancer survivorship. In this article, we review contemporary management of the reproductive health of the female cancer patient.

Hysterectomy-corrected rates of endometrial cancer among women younger than age 50 in the United States.

PURPOSE: This analysis describes the impact of hysterectomy on incidence rates and trends in endometrioid endometrial cancer in the United States among women of reproductive age. METHODS: Hysterectomy prevalence for states containing Surveillance, Epidemiology, and End Results (SEER) registry was estimated using data from the Behavioral Risk Factor Surveillance System (BRFSS) between 1992 and 2010. The population was adjusted for age, race, and calendar year strata. Age-adjusted incidence rates and trends of endometrial cancer among women age 20-49 corrected for hysterectomy were estimated. RESULTS: Hysterectomy prevalence varied by age, race, and ethnicity. Increasing incidence trends were observed, and were attenuated after correcting for hysterectomy. Among all women, the incidence was increasing 1.6% annually (95% CI 0.9, 2.3) and this increase was no longer significant after correction for hysterectomy (+ 0.7; 95% CI - 0.1, 1.5). Stage at diagnosis was similar with and without correction for hysterectomy. The largest increase in incidence over time was among Hispanic women; even after correction for hysterectomy, incidence was increasing (1.8%; 95% CI 0.2, 3.4) annually. CONCLUSION: Overall, endometrioid endometrial cancer incidence rates in the US remain stable among women of reproductive age. Routine reporting of endometrial cancer incidence does not accurately measure incidence among racial and ethnic minorities.

Treatment-Related Radiation Toxicity Among Cervical Cancer Patients.

OBJECTIVE: The purpose of this study is to identify incidence of and factors associated with severe late toxicity in women treated with radiation for cervical cancer. MATERIALS AND METHODS: All patients with cervical cancer treated with radiation as primary or adjuvant therapy from 2005 to 2017 in a single academic institution were included. Records were reviewed for demographic information, Charlson Comorbidity Index, treatment details, toxicities, and outcomes. Patients with and those without severe late gastrointestinal toxicity (SLGIT), severe late genitourinary toxicity (SLGUT), or any SLGIT or SLGUT, defined as any toxicity (AT), were compared. Overall survival and progression-free survival were also compared. RESULTS: Of 179 patients identified, 21.2% had AT, 17.3% had SLGIT, and 10% had SLGUT. Estimated AT rate at 3 years was 24.2%. The mean duration of follow-up was 37 months (range, 3-146 months). Most patients (84.1%) received 3-dimensional conformal therapy, and 15.9% received intensity-modulated radiation therapy. Factors associated with AT were lower body mass index (24.9 vs 28.3, P = 0.043), white race (63.2% vs 44%, P = 0.035), and active tobacco smoking during treatment (59.5% vs 40.2%, P = 0.036). Any toxicity was not associated with 3-dimensional versus intensity-modulated radiation therapy planning, low-dose versus high-dose-rate brachytherapy or time to complete radiation treatment. Higher total cumulative radiation dose to clinical target volume was associated with SLGIT. Progression-free survival and overall survival were similar among patients with AT compared to those without toxicity. CONCLUSIONS: In patients with cervical cancer, radiation toxicity is correlated with lower body mass index, white race, and smoking. Despite technologic advances in radiotherapy planning and delivery, toxicity remains high and interventions to reduce the burden of treatment are needed.

Gynecologic Oncology and Inclusion of Women Into the Surgical Workforce: The Canary in This Coal Mine.

Objective: Women make up a majority of the gynecologic oncology workforce. Increasing the numbers of women in leadership has been proposed as a path towards professional gender equity. This study examined whether leadership gender and departmental infrastructure impact the work environment for women gynecologic oncologists. Methods: Members of a 472-member private Facebook group "Women of Gynecologic Oncology" (WGO) who self-identified as women gynecologic oncologists provided demographics, practice infrastructure, personal experience with workplace bullying, gender discrimination, microaggressions using a REDcap survey platform. Results: Of 250 (53%) respondents to this survey, most were younger than age 50 years (93.6%); White (82.2%) and non-Hispanic (94.3%); married (84.7%); and parenting (75.2%). Practice environments included academic (n=152, 61.0%), hospital employed (n=57, 22.9%), and private practice (n=31, 12.4%), and 89.9% supervised trainees. A significant percent of respondents had experienced bullying (52.8%), gender discrimination (57%) and microaggressions (83%). Age, race, ethnicity, practice setting, or mentorship were not statistically significantly associated with these experiences. Reported perpetrators were varied and included colleagues (84%), patients (44%), staff (41%), administrators (18%), and trainees (16%). Prevalence of bullying (55.0 vs 47.7%, p=0.33), gender discrimination (59.1 vs 52.3%, p=0.33) and microaggressions (83.3 vs 83.0%, p=1.00) were similar irrespective of departmental leadership gender. Conclusions: Women gynecologic oncologists report a high prevalence of workplace bullying, gender discrimination and microaggressions regardless of the gender of their immediate leadership. Proactive and deliberate structural interventions to improve the work environment for surgeons who are women are urgently needed.

Targeted therapy of pyrrolo[2,3-d]pyrimidine antifolates in a syngeneic mouse model of high grade serous ovarian cancer and the impact on the tumor microenvironment.

Novel therapies are urgently needed for epithelial ovarian cancer (EOC), the most lethal gynecologic malignancy. In addition, therapies that target unique vulnerabilities in the tumor microenvironment (TME) of EOC have largely been unrealized. One strategy to achieve selective drug delivery for EOC therapy involves use of targeted antifolates via their uptake by folate receptor (FR) proteins, resulting in inhibition of essential one-carbon (C1) metabolic pathways. FRα is highly expressed in EOCs, along with the proton-coupled folate transporter (PCFT); FRß is expressed on activated macrophages, a major infiltrating immune population in EOC. Thus, there is great potential for targeting both the tumor and the TME with agents delivered via selective transport by FRs and PCFT. In this report, we investigated the therapeutic potential of a novel cytosolic C1 6-substituted pyrrolo[2,3-d]pyrimidine inhibitor AGF94, with selectivity for uptake by FRs and PCFT and inhibition of de novo purine nucleotide biosynthesis, against a syngeneic model of ovarian cancer (BR-Luc) which recapitulates high-grade serous ovarian cancer in patients. In vitro activity of AGF94 was extended in vivo against orthotopic BR-Luc tumors. With late-stage subcutaneous BR-Luc xenografts, AGF94 treatment resulted in substantial anti-tumor efficacy, accompanied by significantly decreased M2-like FRß-expressing macrophages and increased CD3+ T cells, whereas CD4+ and CD8+ T cells were unaffected. Our studies demonstrate potent anti-tumor efficacy of AGF94 in the therapy of EOC in the context of an intact immune system, and provide a framework for targeting the immunosuppressive TME as an essential component of therapy.

Oncogenic B-Myb Is Associated With Deregulation of the DREAM-Mediated Cell Cycle Gene Expression Program in High Grade Serous Ovarian Carcinoma Clinical Tumor Samples.

Cell cycle control drives cancer progression and treatment response in high grade serous ovarian carcinoma (HGSOC). MYBL2 (encoding B-Myb), an oncogene with prognostic significance in several cancers, is highly expressed in most HGSOC cases; however, the clinical significance of B-Myb in this disease has not been well-characterized. B-Myb is associated with cell proliferation through formation of the MMB (Myb and MuvB core) protein complex required for transcription of mitotic genes. High B-Myb expression disrupts the formation of another transcriptional cell cycle regulatory complex involving the MuvB core, DREAM (DP, RB-like, E2F, and MuvB), in human cell lines. DREAM coordinates cell cycle dependent gene expression by repressing over 800 cell cycle genes in G0/G1. Here, we take a bioinformatics approach to further evaluate the effect of B-Myb expression on DREAM target genes in HGSOC and validate our cellular model with clinical specimens. We show that MYBL2 is highly expressed in HGSOC and correlates with expression of DREAM and MMB target genes in both The Cancer Genome Atlas (TCGA) as well as independent analyses of HGSOC primary tumors (N = 52). High B-Myb expression was also associated with poor overall survival in the TCGA cohort and analysis by a DREAM target gene expression signature yielded a negative impact on survival. Together, our data support the conclusion that high expression of MYBL2 is associated with deregulation of DREAM/MMB-mediated cell cycle gene expression programs in HGSOC and may serve as a prognostic factor independent of its cell cycle role. This provides rationale for further, larger scale studies aimed to determine the clinical predictive value of the B-Myb gene expression signature for treatment response as well as patient outcomes.

Reducing Disparities in Receipt of Genetic Counseling for Underserved Women at Risk of Hereditary Breast and Ovarian Cancer.

Purpose: Genetic counseling (GC) provides critical risk prediction information to women at-risk of carrying a genetic alternation; yet racial/ethnic and socioeconomic disparities persist with regard to GC uptake. This study examined patterns of GC uptake after a referral in a racially diverse population. Materials and Methods: In an urban academic medical center, medical records were reviewed between January 2016 and December 2017 for women who were referred to a genetic counselor for hereditary breast and ovarian cancer. Study outcomes were making an appointment (yes/no) and keeping an appointment. We assessed sociodemographic factors and clinical factors. Associations between factors and the outcomes were analyzed using chi square, and logistic regression was used for multivariable analysis. Results: A total of 510 women were referred to GC and most made appointments. More than half were white (55.3%) and employed (53.1%). No significant associations were observed between sociodemographic factors and making an appointment. A total of 425 women made an appointment and 268 kept their appointment. Insurance status (p = 0.003), marital status (p = 0.000), and work status (p = 0.039) were associated with receiving GC. In the logistic model, being married (odds ratio [OR] 2.119 [95% confidence interval, CI 1.341-3.347] p = 0.001) and having insurance (OR 2.203 [95% CI 1.208-4.016] p = 0.021) increased the likelihood of receiving counseling. Conclusions: Racial disparities in GC uptake were not observed in this sample. Unmarried women may need additional support to obtain GC. Financial assistance or other options need to be discussed during navigation as a way to lessen the disparity between women with insurance and those without.

Co-occurring substance use disorder: The impact on treatment adherence in women with locally advanced cervical cancer.

The purpose of this study was to identify the prevalence of substance use disorder and its association with adherence to treatment and survival in locally advanced cervical cancer patients treated with primary radiation therapy. This is a retrospective case series of locally advanced cervical cancer patients with substance use disorder in a single academic institution treated with radiation therapy between 2005 and 2016. Substance use disorder was identified through chart review. Those with substance use disorder were compared to those without in regards to demographics, Charlson comorbidity index, treatment details and outcomes. Of the 129 patients with locally advanced cervical cancer, 16 (12.4%) were identified as having substance use disorder. Patients with substance use disorder were younger (42.1 years vs 51.5 years, p = .013) and more likely to be smokers (81.3% vs 42.5%, p = .004). The majority of patients with substance use disorder received concurrent chemotherapy (93.8%) and brachytherapy in addition to external beam radiation therapy (81.3%). There was no significant difference in days to completion of radiation therapy between patients with and without substance use disorder. Radiation dose received, toxicities and survival were similar between groups. Among cervical cancer patients receiving treatment with radiation therapy, substance use disorder was not associated with poorer adherence, longer radiation treatment times or a difference in total dose of radiation received. Our experience demonstrates that patients with substance use disorder are able to adhere to complex, multimodal treatment plans resulting in similar cancer specific outcomes compared to patients without substance use disorder.

Folate Receptor Alpha Expression in Platinum Resistant/Refractory Ovarian Carcinomas and Primary Endocervical Adenocarcinomas.

INTRODUCTION: Treatment of advanced stage ovarian carcinoma is challenging, and despite surgical treatment and chemotherapy, the 5-year survival rate is estimated around 30%. Early recurrence and resistance to platinum-based chemotherapy are associated with poor prognosis and limited response to available second-line chemotherapy. The relative incidence of endocervical adenocarcinoma (EAC) compared with squamous cell carcinoma is increasing. Although the first-line treatment modality for early stage EAC is surgical resection, for locally advanced disease chemoradiation or neoadjuvant chemotherapy is used. Recently, folate along with its receptor alpha (FRA) has been studied as a potential target in gynecologic malignancy. The objective of this study was to elucidate FRA expression in chemotherapy resistant ovarian cancer and primary EAC. METHODS: FRA expression was evaluated in tissue samples in an epithelial ovarian tumor microarray and 2 study groups: platinum resistant ovarian cancer and primary EAC. Staining intensity was analyzed with a semiquantitative staining algorithm. RESULTS: FRA expression was positive in 32 of 40 (80%) ovarian tumors in the control group. In the platinum resistant ovarian cancer group, FRA was expressed in all 30 samples with moderate to strong staining. None of the EAC samples stained positive for FRA expression. CONCLUSIONS: FRA expression occurs frequently in epithelial ovarian cancer. Our data supports that FRA expressions are maintained after chemotherapy treatment. Folate targeted therapies may be most useful in patients with chemotherapy resistant disease based on high levels of FRA expression in these tumors. There is likely no benefit to folate therapy as an adjuvant treatment in EAC.
