Objective: To describe crowdfunding campaigns by gynecologic cancer patients and to compare campaign characteristics and needs expressed between patients with cervical, uterine, and ovarian cancer.

Study Design: We queried the public crowdfunding forum GoFundMe.

Fallopian tube single cell analysis reveals myeloid cell alterations in high-grade serous ovarian cancer.

Most high-grade serous ovarian cancers (HGSCs) likely initiate from fallopian tube (FT) epithelia. While epithelial subtypes have been characterized using single-cell RNA-sequencing (scRNA-Seq), heterogeneity of other compartments and their involvement in tumor progression are poorly defined. Integrated analysis of human FT scRNA-Seq and HGSC-related tissues, including tumors, revealed greater immune and stromal transcriptional diversity than previously reported.

Cytochrome P450 inhibitor/inducer treatment patterns among patients in the United States with advanced ovarian cancer who were prescribed or were eligible for poly(adenosine diphosphate [ADP]-ribose) polymerase inhibitors in the first-line maintenance setting.

Poly(adenosine diphosphate [ADP]-ribose) polymerase inhibitors (PARPi) are metabolized either via carboxylesterase (niraparib) or cytochrome P450 (CYP) enzymes (olaparib and rucaparib). Patients with advanced epithelial ovarian cancer (aOC) who receive concomitant medication metabolized by the CYP system may be at risk of drug-drug interactions impacting PARPi efficacy and tolerability. This study investigated CYP inhibitor/inducer treatment patterns in the first-line maintenance (1Lm) setting for patients with aOC.

Setting: Major, urban, academic tertiary care hospital in the United States.

Inequities in colorectal and breast cancer screening: At the intersection of race/ethnicity, sexuality, and gender.

Objective: To investigate the joint impact of sexual orientation, gender identity, and race/ethnicity on colorectal and breast cancer screening disparities in the United States.

Methods: Utilizing sampling weighted data from the 2016 and 2018 Behavioral Risk Factor Surveillance System, we assessed differences in two metrics via chi-square statistics: 1) lifetime uptake, and 2) up-to-date colorectal and breast cancer screening by sexual orientation and gender identity, within and across racial/ethnic classifications.

Results: Within specific races/ethnicities, lifetime CRC screening was higher among gay/lesbian (within NH-White, Hispanic, and Asian/Pacific Islander) and bisexual individuals (Hispanic) compared to straight individuals, and lowest overall among transgender women and transgender nonconforming populations ( < 0.

Sexual orientation and gender identity inequities in cervical cancer screening by race and ethnicity.

Background: In the United States, inequities in preventive health behaviors such as cervical cancer screening have been documented. Sexual orientation, gender identity, and race/ethnicity all individually contribute to such disparities. However, little work has investigated their joint impact on screening behavior.

The association of black race with receipt of hysterectomy and survival in low-risk endometrial cancer.

Objective: To determine whether Black race is associated with treatment and survival among women with low-risk endometrial cancer.

Methods: Black and White women with Stage IA grade 1-2 endometrioid endometrial carcinoma diagnosed from 2010 to 2016 in the SEER 18 dataset were identified (n = 23,431), and clinical and socioeconomic attributes obtained. Five-year cancer-specific survival (CSS) and relative survival (RS) were calculated using SEER*Stat 8.

Tyrosine kinase inhibitor toxicities: A society of gynecologic oncology review and recommendations.

Objective: Oral tyrosine kinase inhibitors (TKIs) have new indications for treatment in gynecologic malignancies. These targeted drugs have both unique and overlapping toxicities, which require careful attention and management. New combination therapies with immune-oncology agents have demonstrated promise in endometrial cancer.

Patterns of care and outcomes of risk reducing surgery in women with pathogenic variants in non-BRCA and Lynch syndrome ovarian cancer susceptibility genes.

Objectives: Guidelines recommend risk-reducing bilateral salpingo-oophorectomy (RRSO) for women with pathogenic variants of non-BRCA and Lynch syndrome-associated ovarian cancer susceptibility genes. Optimal timing and findings at the time of RRSO for these women remains unclear. We sought to characterize practice patterns and frequency of occult gynecologic cancers for these women at our two institutions.

Analysis of the Phase III ENGOT-OV16/NOVA Study: Niraparib Efficacy in Germline Wild-type Recurrent Ovarian Cancer with Homologous Recombination Repair Defects.

Unlabelled: In this analysis, we examined the relationship between progression-free survival (PFS) and mutation status of 18 homologous recombination repair (HRR) genes in patients in the non-germline -mutated (non-gm) cohort of the ENGOT-OV16/NOVA trial (NCT01847274), which evaluated niraparib maintenance therapy for patients with recurrent ovarian cancer. This exploratory biomarker analysis was performed using tumor samples collected from 331 patients enrolled in the phase III ENGOT-OV16/NOVA trial's non-gm cohort. Niraparib demonstrated PFS benefit in patients with either somatic mutated (sm; HR, 0.

Doubling down on the future of gynecologic oncology: The SGO future of the profession summit report.

The original vision of the field of gynecologic oncology was to establish a multidisciplinary approach to the management of patients with gynecologic cancers. Fifty years later, scientific advances have markedly changed the overall practice of gynecologic oncology, but the profession continues to struggle to define its value-financial and otherwise. These issues were examined in full at the Society of Gynecologic Oncology (SGO) Future of the Profession Summit and the purpose of this document is to summarize the discussion, share the group's perceived strengths, weaknesses, opportunities, and threats (SWOT) for gynecologic oncologists, further educate members and others within the patient care team about the unique role of gynecologic oncologists, and plan future steps in the short- and long- term to preserve the subspecialty's critical mission of providing comprehensive, longitudinal care for people with gynecologic cancers.

Safety and management of niraparib monotherapy in ovarian cancer clinical trials.

Niraparib is a poly (ADP-ribose) polymerase inhibitor that has shown a significant improvement in progression-free survival irrespective of biomarker status in patients with advanced epithelial ovarian cancer. This review focuses on the adverse events associated with niraparib and their management to maintain efficacy of niraparib treatment and improve quality of life for patients. In five trials assessing efficacy of niraparib in patients with advanced epithelial ovarian cancer (PRIMA, NOVA, NORA, QUADRA, and PRIME), treatment-emergent adverse events of any grade were reported in nearly all patients (≥99%) receiving niraparib; the events were grade ≥3 in 51-74% of patients.

Current gaps and opportunities in screening, prevention, and treatment of cervical cancer.

In their fiscal year 2021 reports, the US House and Senate Appropriations Committees requested that the National Institutes of Health (NIH) evaluate current research related to women's health and topics that include stagnant cervical cancer survival. In response, the NIH Office of Research on Women's Health, with input from women's health experts; members of the public; representatives from NIH institutes, centers, and offices; and members of the NIH Advisory Committee on Research on Women's Health, reviewed the public health needs and current NIH activities on cervical cancer. The Advancing NIH Research on the Health of Women: A 2021 Conference held in October 2021 reviewed these findings and allowed the identification of opportunities to strengthen research.

DNA methylation and transcriptomic features are preserved throughout disease recurrence and chemoresistance in high grade serous ovarian cancers.

Background: Little is known about the role of global DNA methylation in recurrence and chemoresistance of high grade serous ovarian cancer (HGSOC).

Methods: We performed whole genome bisulfite sequencing and transcriptome sequencing in 62 primary and recurrent tumors from 28 patients with stage III/IV HGSOC, of which 11 patients carried germline, pathogenic BRCA1 and/or BRCA2 mutations.

Results: Landscapes of genome-wide methylation (on average 24.

A case of endometrial intraepithelial neoplasia in a transgender man on testosterone therapy.

Testosterone is commonly used as gender-affirming therapy to induce masculinization in transmasculine individuals. The effects of testosterone therapy on endometrial tissue are complex, and while some patients experience endometrial atrophy while taking testosterone, others do not. Reports of gynecologic malignancies, and endometrial cancer in particular, in transmasculine patients taking testosterone are extremely rare (Urban et al.

A multi-level investigation of the genetic relationship between endometriosis and ovarian cancer histotypes.

Endometriosis is associated with increased risk of epithelial ovarian cancers (EOCs). Using data from large endometriosis and EOC genome-wide association meta-analyses, we estimate the genetic correlation and evaluate the causal relationship between genetic liability to endometriosis and EOC histotypes, and identify shared susceptibility loci. We estimate a significant genetic correlation (r) between endometriosis and clear cell (r = 0.

Ovarian Transposition Before Pelvic Radiation Therapy: Spatial Distribution and Dose Volume Analysis.

Purpose: There is a paucity of data analyzing the anatomic locations and dose volume metrics achieved for surgically transposed ovaries in patients desiring fertility or hormonal preservation receiving pelvic radiation therapy (RT), which were examined herein.

Methods And Materials: This is a retrospective study including women who underwent ovarian transposition before pelvic RT between 2010 to 2020. The craniocaudal (CC) distance of the ovary centroid to the (1) plane of the sacral promontory, (2) iliac crest, and (3) the nearest distance between the ovary edge and RT planning target volume (PTV) were measured (cm).

Evaluation of patterns of progression on poly (ADP-ribose) polymerase inhibitor (PARPi) maintenance in ovarian cancer: a cross-sectional study.

Introduction: Despite improvement in progression-free survival with poly (ADP-ribose) polymerase inhibitors (PARPi) as maintenance therapy for ovarian cancer, many patients will eventually progress on therapy. Oligoprogression is uniquely suited to considerations of local consolidation therapy in this setting, but not commonly used in ovarian cancer. In this study we evaluated the proportion of patients on PARPi maintenance who developed limited sites of disease, the location of progression, and their natural history.

Breast cancer surveillance following ovarian cancer in BRCA mutation carriers.

Objectives: BRCA 1 or 2 mutation carriers have increased risk of developing breast cancer (BC) and serous epithelial ovarian cancer (EOC). The incidence of BC over time after EOC is unknown. Optimal BC surveillance for BRCA mutation carriers following EOC has not been defined.

Phase II trial of cisplatin, gemcitabine and pembrolizumab for platinum-resistant ovarian cancer.

Objective: To evaluate the combination of pembrolizumab, cisplatin and gemcitabine in recurrent platinum-resistant ovarian cancer.

Methods: Patients received six cycles of chemotherapy with gemcitabine and cisplatin on day 1 and day 8 of a 21-day treatment cycle. Pembrolizumab was administered on day 1 of cycles 3-6 and as maintenance monotherapy in cycles 7-34.

Single-cell transcriptomics identifies gene expression networks driving differentiation and tumorigenesis in the human fallopian tube.

The human fallopian tube harbors the cell of origin for the majority of high-grade serous "ovarian" cancers (HGSCs), but its cellular composition, particularly the epithelial component, is poorly characterized. We perform single-cell transcriptomic profiling of around 53,000 individual cells from 12 primary fallopian specimens to map their major cell types. We identify 10 epithelial subpopulations with diverse transcriptional programs.

Breast Cancer Surveillance Following Ovarian Cancer in BRCA Mutation Carriers.

1 or 2 mutations result in higher cancer risk for breast cancer (BC) and epithelial ovarian cancer (EOC) for carriers than exists in the general population. Optimal breast imaging surveillance in these patients has not been well defined. An Institutional Review Board-approved, multi-institutional retrospective chart review was performed.
