ABSTRACT

Kidney transplantation offers recipients superior outcomes and improved quality of life compared with dialysis. However, the need for ongoing immunosuppression places recipients at increased risk of certain forms of cancer. Screening and early detection of precancerous lesions are one of the few proven ways to lower the risk of cancer morbidity and mortality in the transplant population. Women have additional barriers to cancer screening services globally, especially in low- and middle-income countries as well as within certain disadvantaged groups in high-income countries. There is a dearth of published data on screening guidelines and policies on post-transplant malignancy in female recipients. It is vital that health care providers and patients are educated regarding the risks of cancer at all post-transplant stages and that the recommended screening policies are adhered to in order to reduce associated morbidity and mortality in this at-risk group.

ABSTRACT

OBJECTIVES: To assess the association of socioeconomic demographics with recommendation for and uptake of risk-reducing bilateral salpingo-oophorectomy (rrBSO) in patients with BRCA1 and BRCA2 (BRCA1/2) mutations. DESIGN: Retrospective cohort, semistructured qualitative interviews. SETTING AND PARTICIPANTS: BRCA1/2 mutation carriers at an urban, public hospital with a racially and socioeconomically diverse population. INTERVENTION: None. PRIMARY AND SECONDARY OUTCOMES: The primary outcomes were rate of rrBSO recommendation and completion. Secondary outcomes were sociodemographic variables associated with rrBSO completion. RESULTS: The cohort included 167 patients with BRCA1/2 mutations of whom 39% identified as black (n=65), 35% white (n=59) and 19% Hispanic (n=32). Over 95% (n=159) received the recommendation for age-appropriate rrBSO, and 52% (n=87) underwent rrBSO. Women who completed rrBSO were older in univariable analysis (p=0.05), but not in multivariable analysis. Completion of rrBSO was associated with residence in zip codes with lower unemployment and documented recommendation for rrBSO (p<0.05). All subjects who still received care in the health system (n=79) were invited to complete interviews regarding rrBSO decision-making, but only four completed surveys for a response rate of 5.1%. Themes that emerged included menopause, emotional impact and familial support. CONCLUSIONS: In this understudied population, genetic counselling and surrogates of financial health were associated with rrBSO uptake, highlighting genetics referrals and addressing social determinants of health as opportunities to improve cancer prevention and reduce health inequities. Our study demonstrates a need for more culturally centred recruiting methods for qualitative research in marginalised communities to ensure adequate representation in the literature regarding rrBSO.

ABSTRACT

INTRODUCTION: Less than half of eligible Black women are assessed for genetic risk and only 28% engage in recommended hereditary breast and ovarian cancer (HBOC) risk-reducing interventions. CHWs are trusted individuals that work as a liaison between health systems and the community to improve access to services and support cancer prevention efforts, though they are an overlooked resource to support genetic risk assessment. To address the need and training gaps for CHWs, we developed and assessed an online training program to build CHW's competencies in cancer genomics and use of health information technologies to navigate high-risk individuals to appropriate genetic services. METHODS: The curriculum and 10 training modules were developed through engaging a panel of experts in a three-round Delphi process. Recruitment focused on CHWs who worked in clinical settings or groups providing outreach or health services to Black women. We assessed: changes in knowledge and attitudes about HBOC and genomics, as well as the perceptions about the quality and implementation of the training. RESULTS: Forty-six individuals expressed interest in the training after recruitment. Thirty eight individuals were eligible for the training and 26 completed the course. We found improvements in knowledge and genomics competencies immediately post-course, but the majority of these improvements were not sustained at 3-month follow-up. The training was highly rated for its relevance to CHW work and overall delivery. Top rated sessions included HBOC overview and family history collection. On average, participants reported discussing HBOC with 17 individuals at 3-month follow-up. CONCLUSION: Championing a diverse cancer and genomics workforce can help address the goals of the National Cancer Plan to improve early detection and health equity. Through this training, CHWs gained critical cancer and genomics knowledge that was then applied to their primary roles.

ABSTRACT

More attention has been paid to immunotherapy for ovarian cancer and the development of tumor vaccines. We developed a trichostatin A (TSA)-modified tumor vaccine with potent immunomodulating activities that can inhibit the growth of ovarian cancer in rats and stimulate immune cell response in vivo. TSA-treated Nutu-19 cells inactivated by X-ray radiation were used as a tumor vaccine in rat ovarian cancer models. Prophylactic and therapeutic experiments were performed with TSA-modified tumor vaccine in rats. Flow cytometry and ELISpot assays were conducted to assess immune response. Immune cell expression in the spleen and thymus were detected by immunohistochemical staining. GM-CSF, IL-7, IL-17, LIF, LIX, KC, MCP-1, MIP-2, M-CSF, IP-10/CXCL10, MIG/CXCL9, RANTES, IL-4, IFN-γ, and VEGF expressions were detected with Milliplex Map Magnetic Bead Panel immunoassay. TSA vaccination in therapeutic and prophylactic models could effectively stimulate innate immunity and boost the adaptive humoral and cell-mediated immune responses to inhibit the growth and tumorigenesis of ovarian cancer. This vaccine stimulated the thymus into reactivating status and enhanced infiltrating lymphocytes in tumor-bearing rats. The expression of key immunoregulatory factors were upregulated in the vaccine group. The intensities of infiltrating CD4+ and CD8+ T cells and NK cells were significantly increased in the vaccine group compared to the control group (P<0.05). This protection was mainly dependent on the IFN-γ pathway and, to a much lesser extent, by the IL-4 pathway. The tumor cells only irradiated by X-ray as the control group still showed a slight immune effect, indicating that irradiated cells may also cause certain immune antigen exposure, but the efficacy was not as significant as that of the TSA-modified tumor vaccine. Our study revealed the potential application of the TSA-modified tumor vaccine as a novel tumor vaccine against tumor refractoriness and growth. These findings offer a better understanding of the immunomodulatory effects of the vaccine against latent tumorigenesis and progression. This tumor vaccine therapy may increase antigen exposure, synergistically activate the immune system, and ultimately improve remission rates. A vaccine strategy designed to induce effective tumor immune response is being considered for cancer immunotherapy.

ABSTRACT

Reproductive cancers, encompassing various malignancies like endometrial, ovarian, cervical cancer, and gestational trophoblastic neoplasia, pose a significant global health burden. Understanding their patterns is vital for effective prevention and management. Contraceptives show a protective effect against some of these cancers. This clinical guidance document aims to elucidate the disease burden of reproductive cancers and the evidence supporting contraceptive methods in prevention and management. Regional disparities in incidence and mortality highlight the urgent need for targeted interventions, particularly in low-resource settings. Healthcare providers must weigh individual risk profiles and medical eligibility criteria when discussing contraceptive options. Enhanced health literacy through direct patient education is essential for leveraging low-cost behavioral interventions to mitigate reproductive cancer risks.

ABSTRACT

The Precision Medicine Initiative was launched upon the potential of genomic information to tailor medical care. Cascade genetic testing represents a powerful application of precision medicine and involves the process of familial diffusion or the "cascade" of genomic risk information. When an individual (proband) is found to carry a cancer-associated germline pathogenic mutation, the information should be cascaded or shared with at-risk relatives. First degree relatives have a 50% likelihood of carrying the same cancer-associated mutation. This process of cascade testing offers at-risk relatives the opportunity for genetic testing and, for those who also carry the cancer-associated mutation, genetically targeted primary disease prevention through intensive cancer surveillance, chemoprevention and risk-reducing surgery, reducing morbidity and preventing mortality. Cascade testing has been designated by the Centers for Disease Control and Prevention as a Tier 1 genomic application for hereditary breast and ovarian cancer. In this manuscript we describe a cascade genetic testing and in particular focus on its potential to provide necessary care to medically underserved and vulnerable populations.

ABSTRACT

Recent studies propose fallopian tubes as the tissue origin for many ovarian epithelial cancers. To further support this paradigm, we assessed whether salpingectomy for treating ectopic pregnancy had a protective effect using the Taiwan Longitudinal National Health Research Database. We identified 316 882 women with surgical treatment for ectopic pregnancy and 3 168 820 age- and index-date-matched controls from 2000 to 2016. In a nested cohort, 91.5% of cases underwent unilateral salpingectomy, suggesting that most surgically managed patients have salpingectomy. Over a follow-up period of 17 years, the ovarian carcinoma incidence was 0.0069 (95% confidence interval [CI] = 0.0060 to 0.0079) and 0.0089 (95% CI = 0.0086 to 0.0092) in the ectopic pregnancy and the control groups, respectively (P < .001). After adjusting the events to per 100 person-years, the hazard ratio (HR) in the ectopic pregnancy group was 0.70 (95% CI = 0.61 to 0.80). The risk reduction occurred only in epithelial ovarian cancer (HR = 0.73, 95% CI = 0.63 to 0.86) and not in non-epithelial subtypes. These findings show a decrease in ovarian carcinoma incidence after salpingectomy for treating ectopic pregnancy.

ABSTRACT

PURPOSE: Carriers of pathogenic variants in BRCA1/2 have an elevated lifetime cancer risk warranting high-risk screening and risk-reducing procedures for early detection and prevention. We report on prevention practices among women with pathogenic BRCA variants in order to document follow through with NCCN recommendations and to identify barriers to guideline-recommended care. METHODS: Our cohort included women who had genetic testing through a cancer genetic clinic and completed a 54-item questionnaire to measure socio-demographics, medical history, rates of cancer screening and risk-reducing surgery, disclosure of test results, and cancer worry. Outcomes included rates of completion of risk-reducing salpingo-oophorectomy (RRSO), risk-reducing mastectomy (RRM), and NCCN risk-reducing and age-dependent screening guidelines (version 3.2019). Multivariable logistic regression analyses were used to evaluate potential predictors of these outcomes. RESULTS: Of 129 evaluable women with pathogenic BRCA1/2 variants, 95 (74%) underwent RRSO and 77 (60%) had RRM, respectively, and 107 (83%) were considered adherent to NCCN guidelines. Women with a history of breast or ovarian cancer were more likely to have RRM (OR = 4.38; 95% CI 1.80-11.51; p = 0.002). Increasing age was associated with an increased likelihood of RRSO (OR = 1.05; 95% CI 1.01-1.09; p = 0.019) and decreased likelihood for RRM (OR = 0.95; 95% CI 0.92-0.99; p = 0.013). Women who had RRM were 3 times more likely to undergo RRSO (OR = 2.81; 95% CI 1.10-7.44; p = 0.025). Women who had genetic testing after June 2013 were less likely to have RRM than those tested before June 2013 (OR = 0.42; 95% CI 0.18-0.95; p = 0.040. None of the other measured factors were associated with rates of RRSO, RRM or follow through with NCCN recommendations. There was near universal (127/129) reported disclosure of genetic test results to family members, resulting in the discovery of a median of 1 relative with a pathogenic variant (range = 0-8). CONCLUSION: An evaluation of follow up practice in a cohort of women with pathogenic variants in BRCA1/2 revealed high rates of reported completion of screening and surgical risk-reducing recommendations. Educational efforts should continue to reinforce the importance of follow-through with guideline recommended care among this high-risk group.

ABSTRACT

PURPOSE: Early diagnosis of ovarian cancer (OC) increases survival rates; however, due to low awareness levels, women may be diagnosed with OC at the advanced stage. The aim of this cross-sectional study is to reveal the OC awareness of Turkish women and affecting factors. METHODS: Participants were invited to study via social media tools between February-June 2022. Data was collected with Personal Information Form and the "OC Awareness Scale" from 446 women. RESULTS: 81% of the participants did not recall OC symptoms, 80.8% recognized OC risk factors. The most frequently recalled and recognized OC symptom is pelvic pain (19.8%; 55.8%, respectively). The most frequently recalled and recognized OC risk factors were smoking (43.1%, 67.9%, respectively) and family history (39%, 58.7%, respectively). 2% of the participants felt very confident in recognizing the signs, 72.9% would seek help within 1-2 days when they recognized the signs of OC. CONCLUSIONS: The awareness of OC was higher among women who had advanced age, higher education, family history and were in menopause. Turkish women have low level of awareness and knowledge about OC symptoms and risk factors. There is an urgent need for an OC awareness campaign that takes into account the socio-demographic characteristics of women. The results of the study may also guide strategies to prevent OC.

ABSTRACT

Objective: To determine the utilization of risk-reducing strategies and screening protocols for ovarian cancer in female BRCA1/2 carriers. Methods: This study was a sub-analysis of female participants from a larger multicenter, cross-sectional survey of BRCA1/2 mutation carriers unaffected by cancer. The questionnaire was administered electronically via email at four institutions located in the northeast United States. Data were analyzed with Fisher's exact test. Results: The survey was completed by 104 female BRCA mutation carriers. BRCA subtypes included 54.3% BRCA2, 41.0% BRCA1, and 2.9% both. The age at which patients underwent genetic testing varied 21.2% were 18-24 years, 25.0% were 25-34 years, 29.8% were 35-44 years, and 24.0% were 45 years or older. Nearly, all respondents (97.1%) reported that a provider had discussed risk-reducing surgeries. Of the 79 females who underwent genetic testing before 45 years of age, 53.2% reported that a health care provider recommended taking combined oral contraceptive pills (COCs) to reduce their risk of ovarian cancer, and, of these women, 88.1% chose to use them. COCs were offered at higher rates among women who were younger at the age of genetic testing (18-24: 86%, 25-34: 62%, 35-44: 23%; p < 0.0001). Approximately half (55.8%) of the respondents reported having been offered increased screening for possible early detection of ovarian cancer, of which 81.0% chose to undergo screening. The majority utilized a combination of transvaginal ultrasound and serum CA125 measurements. There were no differences observed in screening utilization based on BRCA mutation type. Conclusion: In our cohort of female BRCA mutation carriers, risk-reducing surgery was offered to almost all women, whereas only half were offered risk-reducing medication and/or increased screening. Further investigation is needed to identify barriers to the utilization of risk-reducing strategies among this high-risk population.

ABSTRACT

PURPOSE: The U.S. Preventive Services Task Force recommends screening women to identify individuals eligible for genetic counseling based on a priori hereditary breast and ovarian cancer syndrome (HBOC) risk (i.e., risk assessment). However, risk assessment has not been widely integrated into primary care. This qualitative study explored young women's views on implementing routine HBOC risk assessment with a focus on equity and patient-centeredness. METHODS: We conducted group discussions with young women (aged 21-40 years) receiving care in an integrated health care system. Discussion groups occurred in two phases and used a modified deliberative approach that included a didactic component and prioritized developing consensus. Twenty women participated in one of three initial small group discussions (phase one). All 20 were invited to participate in a subsequent large group discussion (phase two), and 15 of them attended. FINDINGS: Key themes and recommendations were as follows. Risk assessment should be accessible, contextualized, and destigmatized to encourage participation and reduce anxiety, particularly for women who do not know their family history. Providers conducting risk assessments must be equipped to address women's informational needs, relieve emotionality, and plan next steps after positive screens. Finally, to minimize differential screening uptake, health care systems must prioritize equity in program design and contribute to external educational and outreach efforts. CONCLUSION: Young women see pragmatic opportunities for health systems to optimize HBOC screening implementation.

ABSTRACT

Ovarian cancer remains the most lethal gynaecological malignancy with 314 000 cases and 207 000 deaths annually worldwide. Ovarian cancer cases and deaths are predicted to increase in Australia by 42% and 55% respectively by 2040. Earlier detection and significant downstaging of ovarian cancer have been demonstrated with multimodal screening in the largest randomised controlled trial of ovarian cancer screening in women at average population risk. However, none of the randomised trials have demonstrated a mortality benefit. Therefore, ovarian cancer screening is not currently recommended in women at average population risk. More frequent surveillance for ovarian cancer every three to four months in women at high risk has shown good performance characteristics and significant downstaging, but there is no available information on a survival benefit. Population testing offers an emerging novel strategy to identify women at high risk who can benefit from ovarian cancer prevention. Novel multicancer early detection biomarker, longitudinal multiple marker strategies, and new biomarkers are being investigated and evaluated for ovarian cancer screening. Risk-reducing salpingo-oophorectomy (RRSO) decreases ovarian cancer incidence and mortality and is recommended for women at over a 4-5% lifetime risk of ovarian cancer. Pre-menopausal women without contraindications to hormone replacement therapy (HRT) undergoing RRSO should be offered HRT until 51 years of age to minimise the detrimental consequences of premature menopause. Currently risk-reducing early salpingectomy and delayed oophorectomy (RRESDO) should only be offered to women at increased risk of ovarian cancer within the context of a research trial. Pre-menopausal early salpingectomy is associated with fewer menopausal symptoms and better sexual function than bilateral salpingo-oophorectomy. A Sectioning and Extensively Examining the Fimbria (SEE-FIM) protocol should be used for histopathological assessment in women at high risk of ovarian cancer who are undergoing surgical prevention. Opportunistic salpingectomy may be offered at routine gynaecological surgery to all women who have completed their family. Long term prospective opportunistic salpingectomy studies are needed to determine the effect size of ovarian cancer risk reduction and the impact on menopause.

ABSTRACT

Estrogen plays a crucial role in ovarian tumorigenesis. Phytoestrogens (PEs) are a type of daily dietary nutrient for humans and possess a mild estrogenic characteristic. This study aimed to assess the correlation of the consumption of dietary PEs with ovarian cancer risk using data in the prostate, lung, colorectal and ovarian (PLCO) cancer screening trial. Participants were enrolled in PLCO from 1993 to 2001. Hazard ratios (HR) and 95% confidence intervals (CI) were utilized to determine the association between the intake of PEs and ovarian cancer occurrence, which were calculated by the Cox proportional hazards regression analysis. In total, 24 875 participants were identified upon completion of the initial dietary questionnaire (DQX). Furthermore, the analysis also included a total of 45 472 women who filled out the diet history questionnaire (DHQ). Overall, after adjustment for confounders, the dietary intake of total PEs was significantly associated with the risk of ovarian cancer in the DHQ group (HRQ4vsQ1 = 0.69, 95% CI: 0.50-0.95; P for trend = 0.066). Especially, individuals who consumed the highest quartile of isoflavones were found to have a decreased risk of ovarian cancer in the DHQ group (HRQ4vsQ1 = 0.68, 95% CI: 0.50-0.94; P for trend = 0.032). However, no such significant associations were observed for the DQX group. In summary, this study suggests that increased dietary intake of total PEs especially isoflavones was linked with a lower risk for developing ovarian cancer. More research is necessary to validate the findings and explore the potential mechanisms.

ABSTRACT

Importance: Pathogenic variants (PVs) in BRCA1, BRCA2, PALB2, RAD51C, RAD51D, and BRIP1 cancer susceptibility genes (CSGs) confer an increased ovarian cancer (OC) risk, with BRCA1, BRCA2, PALB2, RAD51C, and RAD51D PVs also conferring an elevated breast cancer (BC) risk. Risk-reducing surgery, medical prevention, and BC surveillance offer the opportunity to prevent cancers and deaths, but their cost-effectiveness for individual CSGs remains poorly addressed. Objective: To estimate the cost-effectiveness of prevention strategies for OC and BC among individuals carrying PVs in the previously listed CSGs. Design, Setting, and Participants: In this economic evaluation, a decision-analytic Markov model evaluated the cost-effectiveness of risk-reducing salpingo-oophorectomy (RRSO) and, where relevant, risk-reducing mastectomy (RRM) compared with nonsurgical interventions (including BC surveillance and medical prevention for increased BC risk) from December 1, 2022, to August 31, 2023. The analysis took a UK payer perspective with a lifetime horizon. The simulated cohort consisted of women aged 30 years who carried BRCA1, BRCA2, PALB2, RAD51C, RAD51D, or BRIP1 PVs. Appropriate sensitivity and scenario analyses were performed. Exposures: CSG-specific interventions, including RRSO at age 35 to 50 years with or without BC surveillance and medical prevention (ie, tamoxifen or anastrozole) from age 30 or 40 years, RRM at age 30 to 40 years, both RRSO and RRM, BC surveillance and medical prevention, or no intervention. Main Outcomes and Measures: The incremental cost-effectiveness ratio (ICER) was calculated as incremental cost per quality-adjusted life-year (QALY) gained. OC and BC cases and deaths were estimated. Results: In the simulated cohort of women aged 30 years with no cancer, undergoing both RRSO and RRM was most cost-effective for individuals carrying BRCA1 (RRM at age 30 years; RRSO at age 35 years), BRCA2 (RRM at age 35 years; RRSO at age 40 years), and PALB2 (RRM at age 40 years; RRSO at age 45 years) PVs. The corresponding ICERs were -£1942/QALY (-$2680/QALY), -£89/QALY (-$123/QALY), and £2381/QALY ($3286/QALY), respectively. RRSO at age 45 years was cost-effective for RAD51C, RAD51D, and BRIP1 PV carriers compared with nonsurgical strategies. The corresponding ICERs were £962/QALY ($1328/QALY), £771/QALY ($1064/QALY), and £2355/QALY ($3250/QALY), respectively. The most cost-effective preventive strategy per 1000 PV carriers could prevent 923 OC and BC cases and 302 deaths among those carrying BRCA1; 686 OC and BC cases and 170 deaths for BRCA2; 464 OC and BC cases and 130 deaths for PALB2; 102 OC cases and 64 deaths for RAD51C; 118 OC cases and 76 deaths for RAD51D; and 55 OC cases and 37 deaths for BRIP1. Probabilistic sensitivity analysis indicated both RRSO and RRM were most cost-effective in 96.5%, 89.2%, and 84.8% of simulations for BRCA1, BRCA2, and PALB2 PVs, respectively, while RRSO was cost-effective in approximately 100% of simulations for RAD51C, RAD51D, and BRIP1 PVs. Conclusions and Relevance: In this cost-effectiveness study, RRSO with or without RRM at varying optimal ages was cost-effective compared with nonsurgical strategies for individuals who carried BRCA1, BRCA2, PALB2, RAD51C, RAD51D, or BRIP1 PVs.

ABSTRACT

Being a gynecologic oncologist is a privilege. Women with cancer address their challenges with grit and resilience. Their most basic questions motivated my career-long search for scientific answers hidden in genetics, novel therapeutics, and cancer prevention. But medicine is a team sport. Working alongside gifted colleagues and mentoring trainees to assume starring roles on the team has sustained and enriched my career. Advocating for patients and the specialty of gynecologic oncology provided another means to advance research and cancer awareness to improve patient outcomes. The author believe the most exciting times are yet to come.
