Non-cancer endpoints in BRCA1/2 carriers after risk-reducing salpingo-oophorectomy

Current Science and Practice of Surgical and Nonsurgical Opportunities for Ovarian Cancer Prevention

Due to improved understanding of ovarian cancer pathogenesis, we have an unprecedented chance to decrease the burden of disease by maximizing opportunities for prevention. Innovations in surgical options for prevention stem from the discovery that many cases directly or indirectly arise from the fallopian tube. Surgical prevention with salpingectomy alone decreases risk by ≥50%. Effective hormonal and nonhormonal chemopreventive agents are also available. Risk stratification is key to ensuring that options for prevention are appropriately matched to individual risk profile. This evidence-based review provides a critical appraisal of the translational health research endeavors supporting ovarian cancer prevention in clinical practice.

Impact of risk-reducing salpingo-oophorectomy on lipid determinants, HbA1c and CRP

OBJECTIVE

Risk-reducing salpingo-oophorectomy (RRSO) is advised before 40-45 years of age for BRCA1/2 mutation carriers. This study describes the effect of RRSO on lipid determinants, hemoglobin A1c (HbA1c) and C-reactive protein (CRP).

METHODS

A total of 142 women with increased risk of ovarian cancer were included, 92 premenopausal and 50 postmenopausal. Serum levels of low-density lipoprotein (LDL)-cholesterol, high-density lipoprotein (HDL)-cholesterol and total cholesterol, triglycerides, HbA1c and CRP were determined at three points in time: before (T0) and 6 weeks (T1) and 7 months (T2) following RRSO. The Hot Flush Rating Scale was administered at the same time points.

RESULTS

In premenopausal women, levels of HDL-cholesterol, the cholesterol ratio and HBA1c increased significantly over time, although still staying within the reference range. In this group, hot flushes increased over time (p < 0.001). In postmenopausal women, no significant changes were observed following RRSO. At T2, serum LDL-cholesterol, triglycerides, HbA1c and CRP were significantly lower in premenopausal women compared to postmenopausal women, whereas HDL was increased.

CONCLUSIONS

Seven months after RRSO, the lipid profile in premenopausal women had changed, although still staying within the reference range. For postmenopausal women, we did not observe any significant changes. Our results do not suggest a worsening of cardiovascular risk within 7 months of RRSO.

Changes in Bone Density in Carriers of BRCA1 and BRCA2 Pathogenic Variants After Salpingo-Oophorectomy

OBJECTIVE

To evaluate the effect of risk-reducing salpingo-oophorectomy (RRSO) on change in bone mineral density (BMD) in women aged 34-50 years with pathogenic variants in BRCA1 or BRCA2 (BRCA1/2).

METHODS

The PROSper (Prospective Research of Outcomes after Salpingo-oophorectomy) study is a prospective cohort of women aged 34-50 years with BRCA1 or two germline pathogenic variants that compares health outcomes after RRSO to a non-RRSO control group with ovarian conservation. Women aged 34-50 years, who were planning either RRSO or ovarian conservation, were enrolled for 3 years of follow-up. Spine and total hip BMD were measured by dual-energy X-ray absorptiometry (DXA) scans obtained at baseline before RRSO or at the time of enrollment for the non-RRSO group, and then at 1 and 3 years of study follow-up. Differences in BMD between the RRSO and non-RRSO groups, as well as the association between hormone use and BMD, were determined by using mixed effects multivariable linear regression models.

RESULTS

Of 100 PROSper participants, 91 obtained DXA scans (RRSO group: 40; non-RRSO group: 51). Overall, total spine, and hip BMD decreased significantly from baseline to 12 months after RRSO (estimated percent change -3.78%, 95% CI -6.13% to -1.43% for total spine; -2.96%, 95% CI -4.79% to -1.14% for total hip) and at 36 months (estimated percent change -5.71%, 95% CI -8.64% to -2.77% for total spine; -5.19%, 95% CI -7.50% to -2.87% for total hip. In contrast, total spine and hip BMD were not significantly different from baseline for the non-RRSO group. The differences in mean percent change in BMD from baseline between the RRSO and non-RRSO groups were statistically significant at both 12 and 36 months for spine BMD (12-month difference -4.49%, 95% CI -7.67% to -1.31%; 36-month difference -7.06%, 95% CI -11.01% to -3.11%) and at 36 months for total hip BMD (12-month difference -1.83%, 95% CI -4.23% to 0.56%; 36-month difference -5.14%, 95% CI -8.11% to -2.16%). Across the study periods, hormone use was associated with significantly less bone loss at both the spine and hip within the RRSO group compared with no hormone use (P<.001 at both 12 months and 36 months) but did not completely prevent bone loss (estimated percent change from baseline at 36 months -2.79%, 95% CI -5.08% to -0.51% for total spine BMD; -3.93%, 95% CI -7.27% to -0.59% for total hip BMD).

CONCLUSION

Women with pathogenic variants in BRCA1/2 who undergo RRSO before the age of 50 years have greater bone loss after surgery that is clinically significant when compared with those who retain their ovaries. Hormone use mitigates, but does not eliminate, bone loss after RRSO. These results suggest that women who undergo RRSO may benefit from routine screening for BMD changes to identify opportunities for prevention and treatment of bone loss.

BRCA carriers after risk-reducing bilateral salpingo-oophorectomy: menopausal hormone therapy knowledge gaps, and the impact of physicians' recommendations

OBJECTIVE

Female carriers of BRCA1/2 gene mutations are at an increased lifetime risk for breast and ovarian cancers. They are recommended to undergo risk-reducing surgery, including bilateral salpingo-oophorectomy (RR-BSO), upon completion of childbearing. RR-BSO surgery decreases morbidity and mortality but results in early menopause. Menopausal hormone therapy (MHT) is under-utilized despite being shown as safe for carriers. We aim to evaluate the factors associated with decision-making regarding MHT use following RR-BSO in healthy BRCA mutation carriers.

METHODS

Female carriers aged <50 years who underwent RR-BSO and were followed in a multidisciplinary clinic completed online multiple-choice and free-text questionnaires.

RESULTS

A total of 142 women met the inclusion criteria and filled the questionnaire: 83 were MHT users and 59 were non-users. MHT users underwent RR-BSO earlier than non-users (40.82 ± 3.91 vs. 42.88 ± 4.34; p < 0.0001). MHT usage was positively associated with MHT explanation (odds ratio 4.318, 95% confidence interval [CI] [1.341-13.902], p = 0.014), and knowledge regarding the safety of MHT and its effects on general health (odds ratio 2.001, 95% CI [1.443-2.774], p < 0.0001). MHT users and non-users retrospectively evaluated their comprehension of RR-BSO consequences as significantly lower than before surgery (p < 0.001).

CONCLUSION

Post-RR-BSO outcomes, including the effects on women's quality of life and its possible mitigation through MHT use, need to be addressed pre surgery by healthcare providers.

The Psychosocial Impact of the Decision to Undergo Risk-Reducing Salpingo-Oophorectomy Surgery in BRCA Mutation Carriers and the Role of Physician-Patient Communication

Risk-reducing bilateral salpingo-oophorectomy (RRSO) is an effective prophylactic surgery provided to premenopausal women carrying BRCA1 or BRCA2 mutations and presenting an increased risk of developing breast or ovarian cancer. This procedure is related to physiological, sexual, and psychosocial distress, which altogether increase uncertainty and complexity in the clinical decision-making process and post-surgery adaptation. Physician-patient communication (PPC) has been pointed out as a determinant factor in the decision-making to undergo RRSO, and the subsequent adjustment of women. However, studies examining the psychosocial impact of the decision-making process have been scarce and often lack clear theoretical frameworks. While the role of PPC in such processes has been highlighted in a few qualitative studies, there is a paucity of quantitative research addressing this question. Therefore, this narrative review, conducted using a multidisciplinary approach, was planned to: (1) present an updated medical background for RRSO; (2) analyze the psychosocial impact of the decision-making process within a theoretical framework of the Health Belief Model; and (3) discuss the role of PPC in such a decision-making process and in post-surgery. The collected research also enabled the recommendation of some additions to the existing clinical guidelines and the outlining of future research directions.

Long-Term Non-Cancer Risks in People with BRCA Mutations following Risk-Reducing Bilateral Salpingo-Oophorectomy and the Role of Hormone Replacement Therapy: A Review

Risk-reducing bilateral salpingo-oophorectomy (RRBSO) is the gold standard preventative option for BRCA mutation carriers at high risk for ovarian and breast cancer. However, when performed at the recommended ages of 35-45 years, RRBSO induces immediate premature surgical menopause, along with the accompanying adverse psychosocial, cardiovascular, bone, and cognitive health consequences. While these health consequences have been thoroughly studied in the general population, little is known about the long-term health outcomes in the BRCA population. Hormone replacement therapy (HRT) until the average age of natural menopause can help mitigate these health risks, yet the initiation of HRT is a complex decision among BRCA carriers due to concern of increasing the already high risk of breast cancer in these people. This review summarizes the current research on long-term non-cancer risks in BRCA carriers following RRBSO-induced premature surgical menopause, and highlights the existing evidence in support of HRT use in this population.

Knowledge and understanding risk factors and preventive measures for osteoporosis in women: results of a survey in 502 women with and without a migration background

BACKGROUND

Osteoporosis is a disease of the skeletal system associated with loss of bone mass and an increased risk of fractures affecting women more often than men. Identification of the knowledge about osteoporosis and its preventive methods is the backbone of any awareness program. This study investigates the knowledge with a special focus on women with and without a migration background.

METHODS

Data from systematic patient interviews based on a questionnaire were collected at three different sites in Berlin between February and June 2021. The survey included questions assessing migrant background, demographic characteristics, lifestyle habits including physical exercise and smoking, prevention by vitamin D intake and bone densitometry, and information on personal and family medical history. According to the responses, a scale was created to assess the level of knowledge of preventive osteoporosis measures. The ethic committee of the Charité, Medical faculty has approved this study. SPSS (version 24.0) was used for the statistical analyses.

RESULTS

The survey of 502 female patients revealed that 25% had low and 34% no previous knowledge of osteoporosis. Older age and a better education level correlate with a higher knowledge. Patients with gynecologic cancer are less well informed. There is a significant difference in vitamin D intake between migrant and non-migrant women (57% vs. 49%). There were no significant differences regarding the use of bone densitometry.

CONCLUSION

Knowledge of osteoporosis and the possibility of a bone densitometry as well as the implementation of preventive measures is low among women. Therefore, informing patients better should be a priority, with particular attention on the risks and needs of women with a migration background. Specific programs for women with and without migration background should be developed to increase the awareness of osteoporosis.

Bone health after RRBSO among BRCA1/2 mutation carriers: a population-based study

OBJECTIVE

Examine the risks of fractures and osteoporosis after risk-reducing bilateral salpingo-oophorectomy (RRBSO) among women with BRCA1/2 mutations.

METHODS

In this retrospective population-based study in British Columbia, Canada, between 1996 to 2017, we compared risks of osteoporosis and fractures among women with BRCA1/2 mutations who underwent RRBSO before the age of 50 (n=329) with two age-matched groups without known mutations: 1) women who underwent bilateral oophorectomy (BO) (n=3,290); 2) women with intact ovaries who had hysterectomy or salpingectomy (n=3,290). Secondary outcomes were: having dual-energy X-ray absorptiometry (DEXA) scan, and bisphosphonates use.

RESULTS

The mean age at RRBSO was 42.4 years (range, 26-49) and the median follow-up for women with BRCA1/2 mutations was 6.9 years (range, 1.1-19.9). There was no increased hazard of fractures for women with BRCA1/2 mutations (adjusted hazard ratio [aHR]=0.80; 95% confidence interval [CI]=0.56-1.14 compared to women who had BO; aHR=1.02; 95% CI=0.65-1.61 compared to women with intact ovaries). Among women who had DEXA-scan, those with BRCA1/2 mutations had higher risk of osteoporosis (aHR=1.60; 95% CI=1.00-2.54 compared to women who had BO; aHR=2.49; 95% CI=1.44-4.28 compared to women with intact ovaries). Women with BRCA1/2 mutations were more likely to get DEXA-scan than either control groups, but only 46% of them were screened. Of the women with BRCA1/2 mutations diagnosed with osteoporosis, 36% received bisphosphonates.

CONCLUSION

Women with BRCA1/2 mutations had higher risk of osteoporosis after RRBSO, but were not at increased risk of fractures during our follow-up. Low rates of DEXA-scan and bisphosphonates use indicate we can improve prevention of bone loss.

Risk of cardiovascular disease among women carrying BRCA mutations after risk-reducing bilateral salpingo-oophorectomy: A population-based study

OBJECTIVE

Examine the risk of cardiovascular disease (CVD) following risk reducing bilateral salpingo-oophorectomy (RRBSO) among women with BRCA mutations.

METHODS

In this retrospective population-based study in British Columbia, Canada, between 1996 and 2017, we compared the risk of CVD among women with known BRCA mutations who underwent RRBSO before the age of 50 (n = 360) with two groups of age-matched women without known BRCA mutations: 1) women who underwent bilateral oophorectomy (BO) for benign conditions (n = 3600); and, 2) women with intact ovaries who had hysterectomy or salpingectomy (n = 3600). Our primary outcome was CVD (a composite (any of) myocardial infarction, heart failure, and/or cerebrovascular disease). Secondary outcomes included a diagnostic code for predisposing conditions (hypertension, dyslipidemia, and/or diabetes mellitus), and use of cardioprotective medications (statins and/or beta-blockers).

RESULTS

We report no significant increased risk for CVD between women with BRCA mutations and women who underwent BO (aHR = 1.08, 95%CI: 0.72-1.62), but women with BRCA mutations were less likely to be diagnosed with predisposing conditions (aHR = 0.69, 95%CI: 0.55-0.85). Compared to women without BRCA mutations with intact ovaries who underwent hysterectomy or salpingectomy, women with BRCA mutations had significantly increased risk for CVD (aHR = 1.82, 95%CI: 1.18-2.79) and were less likely to be diagnosed with predisposing conditions (aHR = 0.78, 95%CI: 0.62-0.97) and to fill cardioprotective medications (aHR = 0.88, 95%CI: 0.64-1.22).

CONCLUSION

Our results suggest an opportunity for improved prevention of CVD in women with BRCA mutations after prophylactic oophorectomy. Despite the observed lower prevalence of predisposing conditions for CVD and lesser use of cardioprotective medications, this population did not have a lower rate of CVD.

What Happens After Menopause? (WHAM): A prospective controlled study of cardiovascular and metabolic risk 12 months after premenopausal risk-reducing bilateral salpingo-oophorectomy

OBJECTIVE

To prospectively measure cardiometabolic risk 12 months after premenopausal risk-reducing bilateral salpingo-oophorectomy (RRBSO) compared to a similar age comparison group, and the effects of Hormone Therapy (HT) on cardiometabolic risk.

METHODS

Prospective observational study of 95 premenopausal women planning RRBSO and 99 comparisons who retained their ovaries. At baseline and 12 months, blood pressure (BP), Body Mass Index (BMI), waist and hip circumference, fasting total, HDL and LDL cholesterol, triglycerides, high-sensitivity C-reactive protein, glucose and insulin were measured and HOMA-IR was calculated. Chi-square tests, t-tests and adjusted logistic regression models were used to compare groups.

RESULTS

Baseline cardiometabolic phenotypes were similar between groups but more RRBSO participants were overweight/obese with higher waist/hip ratios. By 12 months, BP and cardiometabolic phenotypes were largely unchanged. Paired t-tests showed statistically significant increases in BMI (p = 0.037) and weight (p = 0.042) and larger increases in waist circumference (p < 0.001) and waist-hip ratio (p = 0.009) after RRBSO vs comparisons. However, these were not significant when adjusted for baseline values. After RRBSO 60% initiated Hormone Therapy (HT). Paired t-tests demonstrated that non-HT users had a significantly greater mean increase in waist circumference of 4.3 cm (95% CI 2.0-6.5) compared to 1.3 cm in HT users (95% CI -0.2-2.7, p < 0.001), which remained significant when adjusted for baseline values (p = 0.02). At 12 months, mean waist circumference was 2.94 cm greater in non-HT users compared to HT users.

CONCLUSIONS

Cardiometabolic risk markers are largely unchanged 12 months after RRBSO. Hormone Therapy after RRBSO may prevent against an increase in waist circumference.

Loss of bone density and bone strength following premenopausal risk-reducing bilateral salpingo-oophorectomy: a prospective controlled study (WHAM Study)

Prophylactic oophorectomy is recommended for women at high risk for ovarian cancer, but the associated impact on bone health is of clinical concern. This prospective, controlled study demonstrated substantial loss of bone density and bone strength following surgical menopause. Postoperative hormone therapy alleviated, but not fully prevented, spinal bone loss.

INTRODUCTION

This prospective study investigated bone health in women following premenopausal oophorectomy.

METHODS

Dual-energy x-ray absorptiometry (DXA), peripheral quantitative computed tomography (pQCT), and pQCT-based finite element analysis (pQCT-FEA) were used to assess bone health between systemic hormone therapy (HT) users and non-users after premenopausal risk-reducing bilateral salpingo-oophorectomy (RRBSO) compared with premenopausal controls over 24-month follow-up.

RESULTS

Mean age was 42.4 ± 2.6 years (n = 30) for the surgery group and 40.2 ± 6.3 years for controls (n = 42), and baseline bone measures were similar between groups. Compromised bone variables were observed at 24 months after RRBSO, among which areal bone mineral density (aBMD) at the lumbar spine, tibial volumetric cortical density (Crt vBMD), and tibial bending stiffness (k_bend) had decreased by 4.7%, 1.0%, and 12.1%, respectively (all p < 0.01). In non-HT users, significant losses in lumbar spine (5.8%), total hip (5.2%), femoral neck (6.0%) aBMD, tibial Crt vBMD (2.3%), and k_bend (14.8%) were observed at 24 months (all p < 0.01). HT prevented losses in k_bend, tibial Crt vBMD, and aBMD, except for modest 2.3% loss at the lumbar spine (p = 0.01).

CONCLUSION

This prospective, controlled study of bone health following RRBSO or premenopausal oophorectomy demonstrated substantial loss of bone density and bone strength following RRBSO. HT prevented loss of bone density and bone stiffness, although there was still a modest decrease in lumbar spine aBMD in HT users. These findings may inform decision-making about RRBSO and clinical management following premenopausal oophorectomy.

Attitudes towards risk-reducing early salpingectomy with delayed oophorectomy for ovarian cancer prevention: a cohort study

OBJECTIVE

To determine risk-reducing early salpingectomy and delayed oophorectomy (RRESDO) acceptability and effect of surgical prevention on menopausal sequelae/satisfaction/regret in women at increased ovarian cancer (OC) risk.

DESIGN

Multicentre, cohort, questionnaire study (IRSCTN:12310993).

SETTING

United Kingdom (UK).

POPULATION

UK women without OC ≥18 years, at increased OC risk, with/without previous RRSO, ascertained through specialist familial cancer/genetic clinics and BRCA support groups.

METHODS

Participants completed a 39-item questionnaire. Baseline characteristics were described using descriptive statistics. Logistic/linear regression models analysed the impact of variables on RRESDO acceptability and health outcomes.

MAIN OUTCOMES

RRESDO acceptability, menopausal sequelae, satisfaction/regret.

RESULTS

In all, 346 of 683 participants underwent risk-reducing salpingo-oophorectomy (RRSO). Of premenopausal women who had not undergone RRSO, 69.1% (181/262) found it acceptable to participate in a research study offering RRESDO. Premenopausal women concerned about sexual dysfunction were more likely to find RRESDO acceptable (odds ratio [OR] = 2.9, 95% CI 1.2-7.7, P = 0.025). Women experiencing sexual dysfunction after premenopausal RRSO were more likely to find RRESDO acceptable in retrospect (OR = 5.3, 95% CI 1.2-27.5, P < 0.031). In all, 88.8% (143/161) premenopausal and 95.2% (80/84) postmenopausal women who underwent RRSO, respectively, were satisfied with their decision, whereas 9.4% (15/160) premenopausal and 1.2% (1/81) postmenopausal women who underwent RRSO regretted their decision. HRT uptake in premenopausal individuals without breast cancer (BC) was 74.1% (80/108). HRT use did not significantly affect satisfaction/regret levels but did reduce symptoms of vaginal dryness (OR = 0.4, 95% CI 0.2-0.9, P = 0.025).

CONCLUSION

Data show high RRESDO acceptability, particularly in women concerned about sexual dysfunction. Although RRSO satisfaction remains high, regret rates are much higher for premenopausal women than for postmenopausal women. HRT use following premenopausal RRSO does not increase satisfaction but does reduce vaginal dryness.

TWEETABLE ABSTRACT

RRESDO has high acceptability among premenopausal women at increased ovarian cancer risk, particularly those concerned about sexual dysfunction.

Family history of premature myocardial infarction modifies the associations between bilateral oophorectomy and cardiovascular disease mortality in a US national cohort of postmenopausal women

OBJECTIVE

To test the hypothesis that a family history of premature myocardial infarction (FHPMI) will modify the associations between bilateral salpingo-oophorectomy (BSO) and mortality due to heart disease (HD), cardiovascular disease (CVD), or all-cause mortality with stronger associations observed for BSO occurring before 45 years.

METHODS

We analyzed data from 2,763 postmenopausal women aged 40 years or older who participated in the National Health and Nutrition Examination Survey (1988-1994) and were followed through December 31, 2015. Cox regression was used to estimate adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality outcomes (HD, CVD, and all-cause).

RESULTS

At baseline, the average age was 62 years. There were 610 women with BSO, 338 women with FHPMI, and 95 women with both BSO and FHPMI. During a median follow-up of 22 years, 1,713 deaths occurred of which 395 and 542 were attributed to HD and CVD, respectively. In models adjusting for CVD risk factors and hormone therapy use, HD mortality was greater among women with both BSO and FHPMI compared to those without either of these conditions (HR: 2.88, 95% CI: 1.72-4.82, PInteraction = 0.016). HD mortality was higher among women with FHPMI and BSO at an earlier age (<45 y: HR: 4.32, 95% CI: 1.95-9.50 vs ≥45 y: HR: 1.60, 95% CI: 0.63-4.09). Similar observations were seen for CVD and all-cause mortality.

CONCLUSIONS

In this study, the risk of HD, CVD, and all-cause mortality in women with BSO was modified by an FHPMI with the risk limited to women undergoing BSO at younger ages.

Prospective follow-up of quality of life for participants undergoing risk-reducing salpingo-oophorectomy or ovarian cancer screening in GOG-0199: An NRG Oncology/GOG study

BACKGROUND

Risk-reducing salpingo-oophorectomy (RRSO) and ovarian cancer screening (OCS) are management options for women at increased risk of ovarian cancer. Long-term effects of these interventions on quality of life (QOL) are not well understood.

METHODS

GOG-0199 is a prospective cohort study of women at increased ovarian cancer risk who chose either RRSO or OCS as their risk management intervention. At study entry, 6, 12, 24 and 60 months of follow-up, participants completed the QOL questionnaire, which included the Medical Outcome Study Short Form-36, the Impact of Events Scales, the Center for Epidemiological Studies Depression Scale, the State-Trait Anxiety Inventory, the Functional Assessment of Cancer Therapy - Endocrine Subscale, and the Sexual Activity Questionnaire. QOL measures were compared between the RRSO and OCS cohort at baseline and over time.

RESULTS

Five-hundred-sixty-two participants in the RRSO cohort and 1,010 in the OCS completed the baseline and at least one follow-up questionnaire. At baseline, participants selecting RRSO reported lower health-related QOL (HRQOL), greater ovarian cancer-related stress, greater anxiety, and more depressive symptomatology, which improved during follow-up, especially for ovarian cancer-related stress. Screening was not found to adversely impact HRQOL. Hormone-related menopausal symptoms worsened and sexual functioning declined during follow-up in both cohorts, but more so among participants who underwent RRSO.

CONCLUSIONS

HRQOL improved after surgery among women who chose RRSO and remained stable among participants undergoing screening. The adverse effects of RRSO and screening on short-term and long-term sexual activity and sexual functioning warrant consideration in the decision-making process for high-risk women.

Changes in Bone Mineral Density After Prophylactic Bilateral Salpingo-Oophorectomy in Carriers of a BRCA Mutation

IMPORTANCE

Preventive surgery is strongly recommended for individuals with a BRCA mutation at a young age to prevent ovarian cancer and improve overall survival. The overall effect of early surgical menopause on various health outcomes, including bone health, has not been clearly elucidated.

OBJECTIVE

To evaluate the association of prophylactic bilateral salpingo-oophorectomy with bone mineral density (BMD) loss among individuals with a BRCA mutation.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study of participants with a BRCA mutation who underwent oophorectomy through the University Health Network, Toronto, Ontario, Canada, recruited participants from January 2000 to May 2013. Eligibility criteria included having a BRCA mutation, at least 1 ovary intact prior to surgery, and no history of any cancer other than breast cancer. Bone mineral density was measured using dual-energy x-ray absorptiometry before and after surgery. Data analysis began in December 2018 and finished in January 2019.

MAIN OUTCOMES AND MEASURES

The annual change in BMD from baseline to follow-up was calculated for the following 3 anatomical locations: (1) lumbar spine, (2) femoral neck, and (3) total hip.

RESULTS

A total of 95 women had both a baseline and postsurgery BMD measurement with a mean (SD) follow-up period of 22.0 (12.7) months. The mean (SD) age at oophorectomy was 48.0 (7.4) years. Among women who were premenopausal at time of surgery (50 [53%]), there was a decrease in BMD from baseline to follow-up across the lumbar spine (annual change, -3.45%; 95% CI, -4.61% to -2.29%), femoral neck (annual change, -2.85%; 95% CI, -3.79% to -1.91%), and total hip (annual change, -2.24%; 95% CI, -3.11% to -1.38%). Self-reported hormone therapy use was associated with significantly less bone loss at the lumbar spine (-2.00% vs -4.69%; P = .02) and total hip (-1.38% vs -3.21; P = .04) compared with no hormone therapy use. Among postmenopausal women at time of surgery (45 [47%]), there was also a significant decrease in BMD across the lumbar spine (annual change, -0.82%; 95% CI, -1.42% to -0.23%) and femoral neck (annual change, -0.68%; 95% CI, -1.33% to -0.04%) but not total hip (annual change, -0.18%; 95% CI, -0.82% to 0.46%).

CONCLUSIONS AND RELEVANCE

This study found that oophorectomy was associated with postoperative bone loss, especially among women who were premenopausal at the time of surgery. Targeted management strategies should include routine BMD assessment and hormone therapy use to improve management of bone health in this population.

Cholesterol profile in women with premature menopause after risk reducing salpingo-oophorectomy

This cross-sectional study aimed to investigate the effect of premenopausal risk reducing salpingo-oophorectomy (RRSO) on the cholesterol profile of women at increased ovarian cancer risk and to assess possible effects of age at and time since RRSO. We included 207 women who underwent RRSO before menopausal age (52 years) attending the family cancer clinic of an academic hospital and 828 age-matched women from a general population cohort (PREVEND). Participants filled out a questionnaire on socio-demographic characteristics, lifestyle and medical history, had anthropometric measurements and provided blood samples for assessment of serum levels of total cholesterol, HDL-cholesterol and non-HDL-cholesterol. The correlation between RRSO and cholesterol profile was assessed with logistic regression. Furthermore, subgroup analyses were performed to explore a possible effect of age at and time since RRSO. At a median time of 5.9 years (range 2.3–25.2) after surgery, RRSO was associated with low (< 60 mg/dl) HDL-cholesterol (OR 9.74, 95% CI 5.19–18.26) and high (≥ 160 mg/dl) non-HDL-cholesterol (OR 1.85, 95% CI 1.21–2.82) when adjusting for body mass index, hormone therapy, participation on sports and previous chemotherapy. The observed association was not dependent on age or time since RRSO. The RRSO group had less smokers (19.3 vs. 25.8%) and more participation on sports (45.4 vs. 22.0%). Our results suggest that RRSO is associated with a more atherogenic cholesterol profile, despite a lower prevalence of smoking and higher prevalence of participation on sports as compared to controls. This observation can be useful for physicians involved in the counselling and follow-up of women having RRSO.

Mindfulness-based stress reduction for menopausal symptoms after risk-reducing salpingo-oophorectomy (PURSUE study): a randomised controlled trial

OBJECTIVE

To assess the short- and long-term effects of mindfulness-based stress reduction (MBSR) on the resulting quality of life, sexual functioning, and sexual distress after risk-reducing salpingo-oophorectomy (RRSO).

DESIGN

Randomised controlled trial.

SETTING

A specialised family cancer clinic of the university medical center Groningen.

POPULATION

Sixty-six women carriers of the BRCA1/2 mutation who developed at least two moderate-to-severe menopausal symptoms after RRSO.

METHODS

Women were randomised to an 8-week MBSR training programme or to care as usual (CAU).

MAIN OUTCOME MEASURES

Change in the Menopause-Specific Quality of Life Questionnaire (MENQOL), the Female Sexual Function Index, and the Female Sexual Distress Scale, administered from baseline at 3, 6, and 12 months. Linear mixed modelling was applied to compare the effect of MBSR with CAU over time.

RESULTS

At 3 and 12 months, there were statistically significant improvements in the MENQOL for the MBSR group compared with the CAU group (both P = 0.04). At 3 months, the mean MENQOL scores were 3.5 (95% confidence interval, 95% CI 3.0-3.9) and 3.8 (95% CI 3.3-4.2) for the MBSR and CAU groups, respectively; at 12 months, the corresponding values were 3.6 (95% CI 3.1-4.0) and 3.9 (95% CI 3.5-4.4). No significant differences were found between the MBSR and CAU groups in the other scores.

CONCLUSION

Mindfulness-based stress reduction was effective at improving quality of life in the short- and long-term for patients with menopausal symptoms after RRSO; however, it was not associated with an improvement in sexual functioning or distress.

TWEETABLE ABSTRACT

Mindfulness improves menopause-related quality of life in women after risk-reducing salpingo-oophorectomy.

Bone loss after oophorectomy among high-risk women: an NRG oncology/gynecologic oncology group study

OBJECTIVE

Women undergoing premenopausal oophorectomy for a variety of reasons, including to reduce ovarian or breast cancer risk were evaluated for accelerated bone loss.

METHODS

The Gynecologic Oncology Group (GOG)-0215 randomized phase-II trial of zoledronic acid was initiated to determine if postoophorectomy bisphosphonate therapy could prevent this bone loss. The study was closed after slow accrual prevented evaluation of the primary study endpoint. We analyzed changes in bone mineral density (BMD) among the 80 women randomized to the observation arm of this study, as measured 3, 9, and 18 months postenrollment.

RESULTS

The mean change in BMD from baseline to 18 months was -0.09 (95% CI, -0.12 to -0.07), -0.05 (95% CI, -0.07 to -0.03), and -0.06 (95% CI, -0.07 to -0.05) g/cm across the lumbar spine, right hip, and left hip, respectively. This represents a BMD decrease of -8.5% for the lumbar spine and -5.7% for both the right and left hips from baseline to 18 months' observation.

CONCLUSIONS

These results demonstrate that premenopausal women undergoing oophorectomy clearly experience bone loss, an adverse effect of oophorectomy, which requires attention and active management. BMD should be monitored postoophorectomy, and treated per standard practice guidelines. Future studies will be required to determine if early treatment can mitigate fracture risk, and to test promising therapeutic interventions and novel prevention strategies, such as increased physical activity or alternative medications, in randomized trials.

Ovarian Cancer Prevention in High-risk Women

Ovarian carcinoma is the most lethal malignancy of the female genital tract. Population-based trials in the general population have not demonstrated that screening improves early detection or survival. Therefore, application of prevention strategies is vital to improving outcomes from this disease. Surgical prevention reduces risk and prophylactic risk-reducing salpingo-oophorectomy is the most effective means to prevent ovarian carcinoma in the high-risk patient although the risks do not outweigh the benefits in average risk patients. Other surgical and medical options have unknown or limited efficacy in the high-risk patient. In this review, we define the patient at high risk for ovarian cancer, discuss how to identify these women and weigh their available ovarian cancer prevention strategies.

What Happens After Menopause? (WHAM): protocol for a prospective, multicentre, age-matched cohort trial of risk-reducing bilateral salpingo-oophorectomy in high-risk premenopausal women

INTRODUCTION

Women at high inherited risk of ovarian cancer are advised to undergo risk-reducing bilateral salpingo-oophorectomy (RRBSO) at age 40-45 years or when their families are complete. Most women are premenopausal at this age, so RRBSO will induce surgical menopause. Despite the clear benefits of RRBSO for cancer risk reduction, much less is known about the impact on non-cancer outcomes that contribute to health and well-being and inform surveillance and management strategies.

METHODS AND ANALYSIS

This will be a multicentre, prospective cohort study of 105 premenopausal high-risk women undergoing RRBSO and an age-matched comparison group of 105 premenopausal women not planning oophorectomy or pregnancy in the next 2 years. The aim of this study is to measure the impact of RRBSO on sexual function (primary outcome) at 24 months in high-risk premenopausal women compared with the comparison group. Secondary outcomes include menopausal symptoms and menopause-related quality of life, mood, sleep quality, markers of cardiovascular disease and pre-diabetes, bone density and markers of bone turnover, and the impact of hormone replacement therapy use on these outcomes. Data analysis methods will include logistic and linear regression using general estimating equations accounting for the repeated outcome measurements within each participant.

ETHICS AND DISSEMINATION

The study has been approved by institutional ethics committees at each participating centre. Findings will be disseminated through peer-reviewed publications and conference presentations, and national and international networks of centres managing high-risk women, and will inform national and international clinical guidelines.

TRIAL REGISTRATION NUMBER

The pre-results protocol for this trial is registered with the Australian New Zealand Clinical Trials Registry (anzctr.org.au; registration no: ACTRN12615000082505).

Impact of risk-reducing salpingo-oophorectomy in premenopausal women

OBJECTIVES

To describe implications of premenopausal risk-reducing salpingo-oophorectomy (RRSO) on quality of life, endocrine symptoms, sexual function, osteoporosis, cardiovascular health, metabolic syndrome, cognitive impairment and safety of hormone replacement therapy.

METHODS

We searched the following electronic databases: The Cochrane Library, EMBASE, PsycInfo, and MEDLINE. We selected controlled and uncontrolled trials of premenopausal women undergoing RRSO. Two authors independently assessed studies for inclusion. Reference lists of included reports were searched manually for additional studies.

RESULTS

Surgical menopause leads to more menopausal complaints and sexual dysfunction than natural menopause. Overall quality of life is not affected by surgery. In the limited literature, there is no evidence that RRSO leads to more osteopenia in comparison with natural menopause at a young age. Cohort studies show a slight impaired cardiovascular health. Cognitive function decreases later in life in premenopausal oophorectomized women. Short-term hormone replacement therapy seems to decline postmenopausal complaints and does not seem to increase the risk for breast carcinoma in mutation carriers without a personal history of breast carcinoma.

CONCLUSIONS

The conclusions of this systematic review are limited by the absence of randomized, controlled trials. There is growing evidence from observational studies that RRSO may impact negatively on all-cause non-survival endpoints.

Commercially available lifestyle modification program: randomized controlled trial addressing heart and bone health in BRCA1/2+ breast cancer survivors after risk-reducing salpingo-oophorectomy

PURPOSE

The goal of this RCT was to examine the efficacy and safety of a web-based program to improve cardiovascular and bone health outcomes, among 35 BRCA1/2+ breast cancer survivors who underwent prophylactic oophorectomy and thus experienced premature surgical menopause.

METHODS

A 12-month commercially available web-based lifestyle modification program (Precision Nutrition Coaching) was utilized. Cardiovascular fitness, dietary intake, leisure time activity, body composition, bone mineral density, bone structure, and muscle strength were assessed.

RESULTS

Average adherence to all program components was 74.8 %. Women in the intervention group maintained their cardiovascular fitness level over the 12 months (1.1 ± 7.9 %), while the control group significantly decreased fitness capacity (-4.0 ± 7.5 %). There was a significant difference between groups in percent change of whole body bone area (-0.8 ± 2.5 control and 0.5 ± 1.30 intervention). We also observed decreased BMI (-4.7 ± 6.2 %) and fat mass (-8.6 ± 12.7 %) in the intervention group due to significant concomitant decreases in caloric intake and increases in caloric expenditure. The control group demonstrated decreased caloric intake and decreased lean tissue mass.

CONCLUSIONS

In this population at high risk for detrimental cardiovascular and bone outcomes, a commercially available lifestyle intervention program mitigated a decline in cardiovascular health, improved bone health, and decreased weight through fat loss.

IMPLICATIONS FOR CANCER SURVIVORS

Precision Nutrition Coaching has shown benefit in breast cancer survivors for reduced risk of deleterious cardiovascular and bone outcomes.

Hormone therapy after prophylactic risk-reducing bilateral salpingo-oophorectomy in women who have BRCA gene mutation

Women with a BRCA1 or BRCA2 gene mutation have substantially higher risk for developing not only breast and ovarian cancers, but also for primary peritoneal, Fallopian tube, colonic, pancreatic cancers, uterine papillary serous adenocarcinoma and malignant melanoma. The risk for ovarian cancer ranges from 39 to 49% by 70 years of age in BRCA1 mutation carriers and from 11 to 18% for those with a BRCA2 mutation, whilst breast cancer increases similarly within women who have either the BRCA1 mutation or the BRCA2 mutation, from about 20% in women in their forties, 37% by the age of 50 years, 55% by 60 years and more than 70% by the age of 70 years. Prophylactic risk-reducing bilateral salpingo-oophorectomy (RRBSO) provides significantly greater benefits with the view of reducing the risk for gynecological and breast cancer (decreasing ovarian cancer risk by 85-95%, breast cancer risk by about 53-68% and removes occult or undetected cancers in 2-18% of such women) compared to other conservative options, namely screening/surveillance or use of chemopreventative agents. RRBSO will result in significant menopausal symptoms, increased risk for bone mineral loss, increasing risk for osteopenia and osteoporosis, and cognitive dysfunction. Risk for cardiovascular disease is also increased if the procedure is performed in women less than 50 years of age. This article analyzes the role of RRBSO in women with BRCA1/BRCA2 mutations with no personal history of breast cancer and the impact of hormone therapy on risk for breast and gynecological cancers if used after the procedure to alleviate the resulting menopausal symptoms.

Surveillance and Care of the Gynecologic Cancer Survivor

BACKGROUND

Care of the gynecologic cancer survivor extends beyond cancer treatment to encompass promotion of sexual, cardiovascular, bone, and brain health; management of fertility, contraception, and vasomotor symptoms; and genetic counseling.

METHODS

This is a narrative review of the data and guidelines regarding care and surveillance of the gynecologic cancer survivor. We searched databases including PubMed, Cochrane, and Scopus using the search terms gynecologic cancer, cancer surveillance, and cancer survivor and reached a consensus for articles chosen for inclusion in the review based on availability in the English language and publication since 2001, as well as key older articles, consensus statements, and practice guidelines from professional societies. However, we did not undertake an extensive systematic search of the literature to identify all potentially relevant studies, nor did we utilize statistical methods to summarize data. We offer clinical recommendations for the management of gynecologic cancer survivors based on review of evidence and our collective clinical experience.

RESULTS

Key messages include the limitations of laboratory studies, including CA-125, and imaging in the setting of gynecologic cancer surveillance, hormonal and non-hormonal management of treatment-related vasomotor symptoms and genitourinary syndrome of menopause, as well as recommendations for general health screening, fertility preservation, and contraception.

CONCLUSIONS

A holistic approach to care extending beyond cancer treatment alone benefits gynecologic cancer survivors. In addition to surveillance for cancer recurrence and late treatment side effects, survivors benefit from guidance on hormonal, contraceptive, and fertility management and promotion of cardiovascular, bone, brain, and sexual health.

A comprehensive approach to the identification and management of the BRCA patient

As the testing criteria for BRCA expand, we are identifying a greater number of young women at significant risk for breast and ovarian cancer. Fortunately, there is strong evidence to support risk reduction from mastectomy and oophorectomy. However, these surgeries come with significant psychological and physical health consequences. For breast cancer, screening with mammogram and magnetic resonance imaging may be a reasonable approach for a woman who does not desire surgery. However, there is no evidence to suggest any efficacy in screening for ovarian cancer, and women electing to not undergo surgery must have a detailed discussion with their physician regarding the risks and benefits of different management strategies. As more women are electing to undergo surgical risk reduction, providers must also be able to counsel and care for these women who will face unique health challenges after surgical menopause at a young age. A review of the current evidence behind management of the BRCA woman follows, with a focus on areas of controversy and current research.

Surgical Menopause

In addition to the common symptoms that occur after natural menopause, special considerations apply to women who have had their ovaries removed, particularly when oophorectomy occurs before age 45 years. Women with premenopausal oophorectomy have more severe and prolonged menopausal symptoms. Their risks of adverse mood, heart disease, excessive bone resorption, sexual dysfunction, and cognitive disorders are increased compared with the general population. Retention of the ovaries carries a survival benefit for women at low risk of ovarian malignancy. Women facing oophorectomy should understand the balance of risks and benefits in order to make an informed decision.

Osteoporosis risk and management in BRCA1 and BRCA2 carriers who undergo risk-reducing salpingo-oophorectomy

OBJECTIVE

Characterize current management of osteoporosis risk in BRCA carriers following risk-reducing salpingo-oophorectomy (RRSO).

METHODS

Women with a BRCA1 or BRCA2 mutation who underwent RRSO were identified from a community-based health system in Northern California from 1995 to 2012. Retrospective chart review using the electronic medical record was performed. The primary outcome was the number of women who had a dual-energy X-ray absorptiometry scan post-RRSO. Secondary outcomes included new diagnoses of osteopenia, osteoporosis, and fracture. Information on the following risk factors was also recorded: calcium and vitamin D use, history of breast cancer, chemotherapy, use of aromatase inhibitors, and use of hormone replacement therapy.

RESULTS

Two hundred and twenty five women tested positive for a BRCA1 or BRCA2 mutation and underwent RRSO. Median follow-up was 41 months from testing. Ninety-nine (44.0%) had at least one DXA scan following testing. The median time from RRSO to a diagnosis of bone disease was 29 months (range 1-170). Seventy-two percent had only one DXA scan (range 1-7) following testing. Thirty-two percent had normal results, 55.6% had osteopenia and 12.1% had osteoporosis. Four percent of women had an atraumatic fracture after surgery. Age, breast cancer history, prior chemotherapy, and tamoxifen or aromatase inhibitor (AI) use were not associated with having osteoporosis or osteopenia.

CONCLUSIONS

Women with BRCA mutations who undergo RRSO have many risk factors for bone loss. The majority of these women are not being screened for bone loss. A clear guideline for screening needs to be established to improve detection of post-RRSO bone disease.

Society of Gynecologic Oncology recommendations for the prevention of ovarian cancer

Mortality from ovarian cancer may be dramatically reduced with the implementation of attainable prevention strategies. The new understanding of the cells of origin and the molecular etiology of ovarian cancer warrants a strong recommendation to the public and health care providers. This document discusses potential prevention strategies, which include 1) oral contraceptive use, 2) tubal sterilization, 3) risk-reducing salpingo-oophorectomy in women at high hereditary risk of breast and ovarian cancer, 4) genetic counseling and testing for women with ovarian cancer and other high-risk families, and 5) salpingectomy after childbearing is complete (at the time of elective pelvic surgeries, at the time of hysterectomy, and as an alternative to tubal ligation). The Society of Gynecologic Oncology has determined that recent scientific breakthroughs warrant a new summary of the progress toward the prevention of ovarian cancer. This review is intended to emphasize the importance of the fallopian tubes as a potential source of high-grade serous cancer in women with and without known genetic mutations in addition to the use of oral contraceptive pills to reduce the risk of ovarian cancer.

Bone mineral density and fractures after risk-reducing salpingo-oophorectomy in women at increased risk for breast and ovarian cancer

AIM

Risk-reducing salpingo-oophorectomy (RRSO) reduces ovarian cancer risk in BRCA mutation carriers. RRSO is assumed to decrease bone mineral density (BMD) and increase fracture risk more than natural menopause. We aimed to compare BMD and fracture incidence after premenopausal RRSO to general population data and identify risk factors for low BMD and fractures after RRSO.

METHODS

In 212 women with RRSO at premenopausal age, BMD was measured by dual energy X-ray absorptiometry. Fractures and risk factors were assessed by self-administered questionnaire. Fracture incidence after RRSO was compared to general practitioner data by using standardised incidence ratios (SIRs). Risk factors for low standardised BMD-scores and fractures were identified by regression analyses.

RESULTS

Median age at RRSO was 42years (range 35-65) and duration of follow-up 5years (2-8). Standardised lumbar spine (Z=0.01, p=0.870) and femoral neck BMD (Z=0.15, p=0.019) were not lower than population BMD. Higher age at time of RRSO and use of hormonal replacement therapy were associated with higher, and current smoking with lower standardised BMD-scores. Sixteen women reported 22 fractures. Fracture incidence was not higher than expected from the general population (all fractures: 25-44years: SIR 2.12 [95% confidence interval (CI) 0.85-4.37]; 45-64years: SIR 1.65 [95% CI 0.92-2.72]).

CONCLUSION

Five years after RRSO, BMD and fracture incidence were not different than expected from the general population. Based on these data it appears safe not to intensively screen for osteoporosis within five years after RRSO, although prospective research on the long-term effects of RRSO on bone is warranted.

BRCA1/2 mutation carriers are potentially at higher cardiovascular risk

BRCA1/2 mutation carriers have an elevated risk of developing breast and ovarian cancer at a relatively young age. Risk-reducing salpingo-oophorectomy is an established strategy to tremendously reduce the risk of ovarian cancer. It is recommended to perform this surgery at age 35-40 years (BRCA1) and at age 40-45 years (BRCA2) resulting in an early and abrupt menopause. BRCA1/2 mutation carriers are potentially at higher risk of cardiovascular diseases due to early surgical menopause, and cardiotoxic effects of adjuvant treatment for breast cancer. Furthermore, preliminary results of experimental studies suggest a possible causative function of the BRCA genes in cardiovascular risk. More research on cardiovascular health risks in BRCA1/2 mutation carriers is needed, especially in the field of cardio-oncology, requiring additional attention to potentially cumulative effects on cardiovascular risks in this specific group of women.

Hereditary breast/ovarian cancer syndrome: a primer for obstetricians/gynecologists

An understanding of the diagnosis and clinical management of hereditary breast and ovarian cancer syndrome (HBOC) is essential for obstetricians/gynecologists. This article provides practical information regarding collecting a family history, cancer risk assessment and genetic testing, BRCA-associated cancer prognosis and treatment, screening recommendations, and prevention strategies. Through appropriate cancer risk assessment, women with BRCA1/2 mutations can be identified, and screening and prevention strategies can be used before a diagnosis of cancer occurs. Women's health providers with a strong working knowledge of HBOC are able to improve the quality of care for women and families impacted by BRCA1/2 mutations.

The consequences of risk reducing salpingo-oophorectomy: the case for a coordinated approach to long-term follow up post surgical menopause

Women with germline mutations in BRCA1 and BRCA2 genes have significantly increased lifetime risks of breast and ovarian cancer. To manage both the ovarian and breast cancer risks the current recommendation is undergo a risk reducing salpingo-oophorectomy (RRSO) prior to natural menopause. To date, studies have focussed on quality of life and sexual dysfunction in women who undergo RRSO, but few have reported on the wider physical consequences. We performed a questionnaire study in women with BRCA 1 or 2 gene mutations known to the Peter MacCallum Familial Cancer Centre. We gathered information about ovarian surgery, ongoing follow-up, management of risk factors including osteoporosis, and current severity of menopausal symptoms. Two hundred and nineteen women were surveyed. One hundred and forty-three of 157 responding participants (91 %) reported having RRSO. Sixty one were pre-menopausal at RRSO. Post surgical follow-up rates were generally low, and a minority of women reported recent bone density imaging or pharmaceutical prevention or treatment of osteoporosis. Menopausal symptoms appeared generally mild. No significant differences in symptom severity were observed in women who underwent a pre-menopausal RRSO compared to RRSO after natural menopause. These data indicate that a formalised follow-up protocol is necessary to optimally manage the consequences of a RRSO.

BRCA carriers, prophylactic salpingo-oophorectomy and menopause: clinical management considerations and recommendations

Women who inherit a mutation in either the BRCA1 or BRCA2 gene have greatly elevated lifetime risks of ovarian cancer, fallopian tube cancer and breast cancer. Preventive surgical removal of the ovaries and fallopian tubes (salpingo-oophorectomy) is recommended to these women, often prior to natural menopause, to prevent cancer. The ensuing hormone deprivation may impact on health and quality of life. Most of these women experience menopausal symptoms shortly after surgery; however, there may also be longer term consequences that are less well understood. In this review, we highlight recent studies that examine the implications of salpingo-oophorectomy on health and quality of life in BRCA-positive women and we discuss the care of women following prophylactic surgery.

Major clinical research advances in gynecologic cancer in 2011

The annual review of 2011 comprised 11 themes of major research achievements in gynecologic oncology including breast cancer. A potential paradigm shift in the management of ovarian cancer was reviewed through comprehensive genomic analyses and a tumor-specific new intraoperative fluorescence imaging technique using folate receptor-α targeted agent, which is expected to improve intraoperative staging and more radical cytoreduction. In addition, updates of bevacizumab and poly (ADP-ribose) polymerase inhibitors, risk-reducing salpingo-oophorectomy, and risk evaluation of pelvic mass were discussed. Regarding cervical cancer, this review covered new findings on human papillomavirus vaccines and human papillomavirus tests as well as the current status of clinical trials on locally advanced cervical cancer. The promising role of sentinel lymph node biopsy in the management of early stage endometrial cancer was followed by two notable clinical researches on: exemestane, an aromatase inhibitor, for the prevention of breast cancer and eribulin, a non-taxane microtubule dynamics inhibitor for the treatment of metastatic breast cancer. Lastly, in premenopausal women with breast cancer, the effect of gonadotropin-releasing hormone analogue on the occurrence of chemotherapy-induced early menopause was discussed.
