ABSTRACT

OBJECTIVE: Despite the within-group heterogeneity, Asian American (AA) and Native Hawaiian and Pacific Islander (NH/PI) patients are often grouped together. We compared the patterns of guideline-concordant care for locally advanced cervical cancer for disaggregated AA and NH/PI patients. METHODS: Patients with stage II-IVA cervical cancer between 2004 and 2020 were identified from the National Cancer Database. AA patients were disaggregated as East Asian (EA), South Asian (SA), and Southeast Asian (SEA). NH/PI patients were classified as a distinct racial subgroup. The primary outcome was the proportion undergoing guideline-concordant care, defined by radiation therapy with concurrent chemotherapy, brachytherapy, and completion of treatment within eight weeks. RESULTS: Of 48,116 patients, 2107 (4%) were AA and 171 (<1%) were NH/PI. Of the AA patients, 36% were SEA, 31% were EA, 12% were SA, and 21% could not be further disaggregated due to missing or unknown data. NH/PI patients were more likely to be diagnosed at an early age (53% NH/PI vs. 30% AA, p < 0.001) and have higher rates of comorbidities (18% NH/PI vs. 14% AA, p < 0.001). Within the AA subgroups, only 82% of SEA patients received concurrent chemotherapy compared to 91% of SA patients (p = 0.026). SA patients had the longest median OS (158 months) within the AA subgroups compared to SEA patients (113 months, p < 0.001). CONCLUSION: Disparities exist in the receipt of standard of care treatment for cervical cancer by racial and ethnic subgroups. It is imperative to disaggregate race and ethnicity data to understand potential differences in care and tailor interventions to achieve health equity.

ABSTRACT

BACKGROUND: Participation in clinical trials may help mitigate disparate cancer outcomes. Thus, ensuring equitable access to clinical trials is a major priority for national cancer organizations. OBJECTIVE: This study aimed to examine clinical trial eligibility criteria that may adversely affect the enrollment of underrepresented groups and assess the availability of demographic information in published gynecologic oncology studies. STUDY DESIGN: ClinicalTrials.gov was searched for gynecologic oncology studies conducted between 1997 and 2021. Each study's inclusion and exclusion criteria were reviewed to determine whether demographic factors were used for enrollment screening. For published studies, demographic variables that were reported were identified. The expected clinical trial enrollment based on disease incidence and mortality was compared with the observed trial enrollment based on race. RESULTS: There were 1597 gynecologic oncology studies: 883 (55%) from ovarian cancer studies, 336 (21%) from cervical cancer studies, 262 (17%) from uterine cancer studies, and 116 (7%) from multisite gynecologic oncology studies. Of the 581 published studies, 554 (95%) reported age, 363 (63%) reported race, and 171 (29%) reported ethnicities. Cervical cancer studies were most likely to report demographic information, including race (P=.026) and ethnicity (P<.001). During the study period, 189 studies (12%) excluded patients based on the language spoken. Industry-sponsored trials (odds ratio, 0.07; 95% confidence interval, 0.02-0.30) and organization-sponsored trials (odds ratio, 0.40; 95% confidence interval, 0.22-0.73) were less likely to exclude patients because of language than investigator-initiated trials. A minority of patients (37%) in cervical cancer trials were of White race, compared with 85% of patients in uterine cancer trials and 82% of patients in ovarian cancer trials. CONCLUSION: Over the last 3 decades, 1 in 10 gynecologic oncology trials excluded patients because of language. Race and ethnicity were reported in more than half of the available studies. Initiatives to increase transparency in recruiting underrepresented patients and reporting demographic data are urgently needed.

ABSTRACT

OBJECTIVE: The real-world management of patients with non-BRCA, homologous recombination repair pathway variants with increased or uncertain risks of ovarian cancer is unknown. The objective was to determine the adoption of risk-reducing salpingo-oophorectomy (RRSO) for carriers of variants with increased or uncertain risks of ovarian cancer beyond BRCA. METHODS: This was a retrospective cohort study of patients at three hospitals with non-BRCA, homologous recombination repair pathway variants with increased risk (BRIP1, RAD51C, RAD51D) and uncertain risk (ATM, BARD1, NBN, PALB2) of ovarian cancer. Outcomes of interest were adoption of RRSO and factors associated with adoption of RRSO. Wilcoxon rank-sum, chi-square, and logistic regression were performed with p < 0.05. RESULTS: Of 318 patients, 76 (24%) had pathogenic variants with increased risks of ovarian cancer (BRIP1, 45; RAD51C, 20; RAD51D, 11), and 242 (76%) had variants with uncertain risks of ovarian cancer (ATM, 145; PALB2, 69; NBN, 23; BARD1, 5). Of 64 patients eligible for RRSO by National Comprehensive Cancer Network (NCCN) criteria or family history, 31 (48%) underwent RRSO. Among eligible patients who did not undergo RRSO, 24 (73%) were not referred for gynecologic oncology consultation. Older age at testing (adjusted odds ratio [aOR] 1.08, 95% confidence interval [CI] 1.03-1.13) and referral to gynecologic oncology (aOR 33.48, CI 8.10-138.39) were associated with increased adoption of RRSO when adjusting for personal and family history of breast and ovarian cancer. CONCLUSION: Half of RRSO-eligible patients by NCCN criteria beyond BRCA did not undergo RRSO. Opportunities exist for improving education to increase referrals to facilitate RRSO for these patients.

ABSTRACT

OBJECTIVE: The objective of this study was to determine the proportion of patients meeting the National Comprehensive Cancer Network (NCCN)'s BRCA genetic testing criteria prior to a diagnosis of a BRCA-related cancer. METHODS: This was a cross-sectional study of patients with BRCA pathogenic variants and a diagnosis of a BRCA-related cancer. Patients were included if they had known dates of genetic testing and cancer diagnosis. NCCN criteria (version 2.2021) were applied to determine if patients met criteria for testing before a BRCA-related cancer diagnosis. The outcome of interest was the proportion of patients undergoing genetic testing following a diagnosis of a BRCA-related cancer who qualified for genetic testing based on NCCN criteria. Chi-square, Mann-Whitney U test, and logistic regression were performed with significance at p < 0.05. RESULTS: Of 270 patients with a BRCA-related cancer, 229 (85%) underwent genetic testing after a cancer diagnosis. Most patients (97%) met at least one NCCN criteria for BRCA testing; 166 (73%) of patients who were tested following a BRCA-related cancer diagnosis also met the criteria for testing by family history. Publicly insured or uninsured patients were three times more likely to undergo BRCA testing after a diagnosis of cancer (odds ratio [OR] 3.03, 95% confidence interval [CI] 1.09-8.40). Patients with a family history of pathogenic variants were more likely to undergo testing before a cancer diagnosis (OR 0.10, 95% CI 0.05-0.23). CONCLUSION: Most patients with BRCA-associated cancers undergo genetic testing after their cancer diagnosis. Increased education on genetic testing criteria and novel methods to improve testing are desperately needed.

ABSTRACT

OBJECTIVE: This study aimed to analyze factors associated with concurrent uterine surgery in patients undergoing bilateral salpingo-oophorectomy (BSO) for risk reducing or therapeutic purposes. Additionally, trends in surgical choice and uptake of post-operative hormone therapy (HT) were examined. METHODS: A 10-year retrospective study was conducted on patients who underwent risk-reducing or therapeutic BSO at one institution. Multinomial regression analysis of patient and case characteristics was performed evaluating associations with surgery type (BSO, BSO and hysterectomy, or BSO and endometrial sampling). Trends in surgery type and uptake of HT post operatively are described. RESULTS: Among the study sample of 643 patients, 140 (22%) patients underwent therapeutic BSO for a history of hormone receptor (HR) positive breast cancer, while the remainder underwent risk-reducing BSO due to a pathogenic variant and/or family history. Pathogenic variants included BRCA1 (141, 40%) BRCA2 (173, 49%), and Lynch syndrome genes (15, 4%). Regression analysis revealed significant associations between concurrent hysterectomy and Black race (RR = 3.55, CI = 1.51-8.38, p = 0.004), history of HR positive breast cancer (RR = 1.88, CI = 1.03-3.42, p = 0.04), and surgeon (Surgeon 1, RR = 2.43, CI = 1.36-4.35, p = 0.003). Among eligible patients under age 51, 36% initiated HT. Over the study period, concurrent hysterectomy rates declined while endometrial sampling increased. CONCLUSIONS: Rates of hysterectomy declined over the study period and slightly more than one-third of eligible patients utilized post-operative HT. Further research on concurrent uterine surgery is needed to establish standardized treatment recommendations in the risk-reducing and therapeutic BSO population. Additionally, education regarding the benefits of postoperative HT in eligible patients is warranted.

ABSTRACT

OBJECTIVE: To explore the use of Gynecologic Oncology Group 258 (GOG 258) study regimens before, during, and after the study. METHODS: Patients aged 18 years or older with endometrial cancer between 2004-2019 were identified in the National Cancer Database. Inclusion criteria were stage III or IVA of any histology and stage I-IVA clear cell or serous histologies with positive washings that received adjuvant therapy. Adjuvant therapy use was examined in the pre-GOG 258 era (before 2009), during GOG 258 enrollment and maturation (2010-2017), and after results presentation in 2017 (2018-2019). Two-sided Cochran-Armitage tests, Wilcoxen rank sum tests, and χ2 tests were used for continuous and categorical variables. Multi-variable logistic regression assessed factors associated with the receipt of chemoradiotherapy compared with chemotherapy only or radiation therapy only. RESULTS: From 2004 to 2019, 41 408 high-risk endometrial cancer patients received adjuvant therapy (12% radiation therapy, 38% chemotherapy, 50% chemoradiotherapy). Chemoradiotherapy increased over the GOG 258 study period (40% before study opening, 54% during enrollment, and 59% after results). Serous (OR 0.6, 95% CI 0.6 to 0.7) and clear cell histology (0.7, 0.6 to 0.8), higher grade (0.8, 0.7 to 0.9), and lymph node positivity (0.8, 0.7 to 0.9) were negatively associated with receipt of chemoradiotherapy compared with single-modality treatment. Non-Hispanic Black ethnicity (0.8, 0.8 to 0.9) and residing ≥50 miles from the treatment facility (0.8, 0.7 to 0.9) were also negatively associated with chemoradiotherapy. Private insurance (1.2, 1.0 to 1.4) and treatment at community hospitals (1.2, 1.2 to 1.3) were positively associated with chemoradiotherapy. CONCLUSION: Despite the lack of benefit in the GOG 258 experimental arm, chemoradiotherapy use increased during study enrollment and after results publication.

ABSTRACT

OBJECTIVE: To evaluate the role of diffusion-weighted imaging (DWI) in the initial diagnosis, staging, and assessment of treatment response in patients with multiple myeloma (MM). MATERIALS AND METHODS: A systematic literature review was conducted in PubMed, the Cochrane Library, EMBASE, Scopus, and Web of Science databases. The primary endpoints were defined as the diagnostic performance of DWI for disease detection, staging of MM, and assessing response to treatment in these patients. RESULTS: Of 5881 initially reviewed publications, 33 were included in the final qualitative and quantitative meta-analysis. The diagnostic performance of DWI in the detection of patients with MM revealed pooled sensitivity and specificity of 86% (95% CI: 84-89) and 63% (95% CI: 56-70), respectively, with a diagnostic odds ratio (OR) of 14.98 (95% CI: 4.24-52.91). The pooled risk difference of 0.19 (95% CI: - 0.04-0.42) was reported in favor of upstaging with DWI compared to conventional MRI (P value = 0.1). Treatment response evaluation and ADCmean value changes across different studies showed sensitivity and specificity of approximately 78% (95% CI: 72-83) and 73% (95% CI: 61-83), respectively, with a diagnostic OR of 7.21 in distinguishing responders from non-responders. CONCLUSIONS: DWI is not only a promising tool for the diagnosis of MM, but it is also useful in the initial staging and re-staging of the disease and treatment response assessment. This can aid clinicians with earlier initiation or change in treatment strategy, which could have prognostic significance for patients.

ABSTRACT

BACKGROUND: Timely genetic testing at ovarian cancer diagnosis is essential as results impact front line treatment decisions. Our objective was to determine rates of genetic counseling and testing with an expedited genetics referral pathway wherein women with newly-diagnosed ovarian cancer are contacted by a genetics navigator to facilitate genetic counseling. METHODS: Patients were referred for genetic counseling by their gynecologic oncologist, contacted by a genetics navigator and offered appointments for genetic counseling. Patients completed quality of life (QoL) surveys immediately pre- and post-genetic assessment and 6 months later. The primary outcome was feasibility of this pathway defined by presentation for genetic counseling. RESULTS: From 2015 to 2018, 100 patients were enrolled. Seventy-eight had genetic counseling and 73 testing. Median time from diagnosis to genetic counseling was 34 days (range 10-189). Among patients who underwent testing, 12 (16%) had pathogenic germline mutations (BRCA1-7, BRCA2-4, MSH2-1). Sixty-five patients completed QoL assessments demonstrating stress and anxiety at time of testing, however, scores improved at 6 months. Despite the pathway leveling financial and logistical barriers, patients receiving care at a public hospital were less likely to present for genetic counseling compared to private hospital patients (56% versus 84%, P = 0.021). CONCLUSIONS: Facilitated referral to genetic counselors at time of ovarian cancer diagnosis is effective, resulting in high uptake of genetic counseling and testing, and does not demonstrate a long term psychologic toll. Concern about causing additional emotional distress should not deter clinicians from early genetics referral as genetic testing can yield important prognostic and therapeutic information.

ABSTRACT

PURPOSE: The objective of this study was to investigate stress levels among women undergoing elective oocyte cryopreservation by comparing their self-reported quality of life measures with women undergoing in vitro fertilization during the fertility treatment cycle. METHODS: Patients undergoing oocyte retrieval at a single institution were offered a voluntary, anonymous, and written questionnaire. The survey was adapted and validated from the Fertility Quality of Life tool to assess self-reported fertility treatment-related problems and was tested for construct validity and reliability. Based on exploratory factor analyses, three subscales were created as follows: fertility treatment-related stress, tolerability, and environment. Relationships between patient characteristics and fertility treatment-related measures were examined with Fisher's exact test, ANOVA, and multivariate regression with significance p < 0.05. RESULTS: A total of 461 patients (331 IVF, 130 egg freeze) were included in the analysis. Medically indicated egg freezing patients were excluded. Overall, both IVF and egg freeze patients reported stress during the current fertility cycle and there were no significant differences between IVF and egg freeze patients for any subscale scores. Three sets of generalized linear models were run and found age to be associated with fertility treatment-related stress and tolerability scores, with younger patients experiencing greater difficulties. Additionally, patients who underwent repeat cycles reported more fertility treatment-related stress. CONCLUSIONS: Patients undergoing egg freezing have similar responses to quality of life questions as patients undergoing IVF. Repeat cycles and younger age contribute to perceptions of stress. This information supports developing stress reduction strategies for all women undergoing egg freezing.

ABSTRACT

BACKGROUND: Tenofovir alafenamide (TAF) is associated with less renal and bone toxicity compared with tenofovir disoproxil (TDF). TAF's recent FDA approval has spurred HIV providers to consider switching antiretroviral therapy (ART) regimens containing TDF to TAF to minimize long term risks. Patient views on the process of such medication switches have not been explored. METHODS: Patients taking elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (E/C/F/TDF) following the Food and Drug Administration's (FDA) approval of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) received medication education from an HIV pharmacist prior to switching to the tenofovir alafenamide (TAF) formulation. Patients were asked to complete a cross-sectional survey assessing satisfaction with the switch process and knowledge about the new medication 4 to 8 weeks post-switch. RESULTS: Sixty five patients completed the switch and 57 (88%) completed a follow-up survey. Most (86%) reported understanding why the switch was made, while 91% correctly identified that TAF is associated with reduced renal toxicity, and 73% correctly identified that TAF is associated with reduced bone toxicity. No statistically significant difference was found in satisfaction with or understanding of why the medication switch was made when assessed by sex, age, race, or education, but there was a trend toward significance in the distribution of answers based on education level with those with a high school diploma, General Educational Development (GED) or less being more likely to be satisfied with the medication switch (p = 0.074). CONCLUSIONS: Education from an ambulatory clinic-based HIV pharmacist resulted in high rates of patient satisfaction and understanding of the switch from TDF to TAF-containing ART.

ABSTRACT

BACKGROUND: Mechanical alteration of the cervical angle has been proposed to reduce spontaneous preterm birth. Performance of the uterocervical angle as measured by ultrasound for predicting spontaneous preterm birth is poorly understood. OBJECTIVE: We sought to determine whether a novel ultrasonographic marker, uterocervical angle, correlates with risk of spontaneous preterm birth in a general population. STUDY DESIGN: We conducted a retrospective cohort study from May 2014 through May 2015 of singleton gestations between 16 0/7-23 6/7 weeks undergoing transvaginal ultrasound for cervical length screening. Images were remeasured for uterocervical angle between the lower uterine segment and the cervical canal. Primary outcome was prediction of spontaneous preterm birth <34 weeks and <37 weeks by uterocervical angle and secondary outcome evaluated cervical length and spontaneous preterm birth. RESULTS: A total of 972 women were studied. The rate of spontaneous preterm birth in this cohort was 9.6% for delivery <37 weeks and 4.5% for <34 weeks. Uterocervical angle of ≥95 degrees was significantly associated with spontaneous preterm birth <37 weeks with sensitivity of 80% (P < .001; confidence interval, 0.70-0.81; negative predictive value, 95%). Uterocervical angle of ≥105 degrees predicted spontaneous preterm birth <34 weeks with sensitivity of 81% (P < .001; confidence interval, 0.72-0.86; negative predictive value, 99%). Cervical length ≤25 mm significantly predicted spontaneous preterm birth <37 weeks (P < .001; sensitivity, 62%; negative predictive value, 95%) and <34 weeks (P < .001; sensitivity, 63%; negative predictive value, 97%). Regression analysis revealed a significant association of maternal age, nulliparity, race, and obesity at conception with spontaneous preterm birth and uterocervical angle. There was no correlation identified between history of dilation and curettage, abnormal Pap smear results, excisional cervical procedures, smoking, or obesity at delivery on spontaneous preterm birth and uterocervical angle. CONCLUSION: A wide uterocervical angle ≥95 and ≥105 degrees detected during the second trimester was associated with an increased risk for spontaneous preterm birth <37 and <34 weeks, respectively. Uterocervical angle performed better than cervical length in this cohort. Our data indicate that uterocervical angle is a useful, novel transvaginal ultrasonographic marker that may be used as a screening tool for spontaneous preterm birth.

ABSTRACT

In this work, we briefly report some attempts to control regioisomeric bisadditions on Sc3N@Ih-C80 and Lu3N@Ih-C80 using the tether-controlled multifunctionalization method. We then describe the use of independent (nontethered) bis-1,3-dipolar cycloaddition reactions and the characterization of 5 new bisadducts, 3 for Sc3N@C80 and 2 for Lu3N@C80, which have never been reported before. Unexpectedly and remarkably, 4 of these compounds exhibit relatively high symmetry and 2 of these bisadducts are the first examples of intrinsically chiral endohedral compounds, due to the addition pattern, not to the presence of chiral centers on the addends. Since an analysis of the statistically possible number of bisadduct isomers on an Ih-C80 cage has not been reported, we present it here.

ABSTRACT

Traditional prognostic models for newly diagnosed patients with multiple myeloma (MM), including International Staging System criteria and number of high-risk chromosomal abnormalities, are based on disease characteristics at diagnosis. However, the identification of patients at risk of more rapidly progressive MM is inherently a dynamic assessment. In a subset of patients with MM, adverse disease biology only becomes evident after the failure of first-line therapy. We define this entity as functional high-risk MM (FHRMM), encompassing relapse within 18 months of treatment initiation and/or within 12 months of frontline autologous stem cell transplantation. FHRMM is not adequately captured by traditional prognostic models, and there is a need for better understanding of mechanisms or risk factors for early relapse or progression. In this review, we explore potential definitions of FHRMM before delving into its underlying drivers based on genetic, transcriptomic, and immune cell profiling studies. Emerging data suggest that specific features of both myeloma cells and immune cells can enable the FHRMM phenotype. We conclude our review by discussing ongoing and future studies that seek to identify and intervene upon patients with FHRMM preemptively.

ABSTRACT

Autologous chimeric antigen receptor T-cell (CAR-T) therapies targeting B-cell maturation antigen (BCMA) have revolutionized the field of multiple myeloma in the same way that the Ford Model T revolutionized the original CAR world a century ago. However, we are only beginning to understand how to improve the efficacy and usability of these cellular therapies. In this review, we explore three automotive analogies for innovation with BCMA CAR-T therapies: stronger engines, better mileage, and hassle-free delivery. Firstly, we can build stronger engines in terms of BCMA targeting: improved antigen binding, tools to modulate antigen density, and armoring to better reach the antigen itself. Secondly, we can improve "mileage" in terms of response durability through ex vivo CAR design and in vivo immune manipulation. Thirdly, we can implement hassle-free delivery through rapid manufacturing protocols and off-the-shelf products. Just as the Model T set a benchmark for car manufacturing over 100 years ago, idecabtagene vicleucel and ciltacabtagene autoleucel have now set the starting point for BCMA CAR-T therapy with their approvals. As with any emerging technology, whether automotive or cellular, the best in innovation and optimization is yet to come.

ABSTRACT

Introduction: Elective surgical procedures were suspended during the coronavirus disease pandemic (COVID-19) in New York City (NYC) between March 16 and June 15, 2020. This study characterizes the impact of the ban on surgical delays for patients scheduled for surgery during this first wave of the COVID-19 outbreak. Methods: Patients who were scheduled for surgical treatment of malignant or pre-invasive disease by gynecologic oncologists at three NYC hospitals during NYC's ban on elective surgery were included. Outcomes of interest were the percentage of patients experiencing surgical delay and the nature of delays. Kruskal-Wallis, chi-square, and logistic regression tests were performed with significance set at p < 0.05. Results: Of the 145 patients with malignant or pre-invasive diseases scheduled for surgery during the ban on elective surgery, 40% of patients experienced one or more surgical delays, 10% experienced two or more and 1% experienced three surgical delays. Of patients experiencing an initial delay, 77% were hospital-initiated and 11% were due to known or suspected personal COVID-19. Overall, 81% of patients completed their planned treatment, and 93% of patients underwent their initially planned surgery. Among patients for whom adjuvant therapy was recommended, 67% completed their planned treatment, and the most common reasons for not completing treatment were medically indicated followed by concerns regarding COVID-19. Conclusion: During the ban on elective surgery in NYC during the first outbreak of the COVID-19 pandemic, many patients experienced minor surgical delays, but most patients obtained appropriate, timely care with either surgery or alternative treatment.

ABSTRACT

OBJECTIVE: Although recurrence rates after radiotherapy for solitary plasmacytoma (SP) are well established, little is known about how SP responds radiographically, as most historical patients were treated in the 2D era. We evaluated the response to radiotherapy among SP patients staged and treated with 3D techniques, including proton therapy, which has not yet been previously reported. METHODS AND MATERIALS: Between 2007 and 2021, 15 SP patients (4 extramedullary, 11 bone) staged with 3D imaging and bone marrow evaluation were consecutively treated with definitive radiotherapy. The best response was categorized in 9 evaluable patients according to response evaluation criteria in solid tumors (RECIST) and positron emission tomography response criteria in solid tumors (PERCIST). RESULTS: With a median follow-up of 34 months, 4 patients relapsed. The median time to the best response was ~2 years (26.6 mo RECIST, 25.4 mo PERCIST). Response rates differed based on response assessment criteria. PERCIST was associated with higher rates of complete (85.7%) or partial response (14.3%) compared with RECIST (16.7% complete, 33.3% partial). Two-year and 4-year PFS for extramedullary SP were 100% and 75%, compared with 91% and 55% for bone ( P =0.75). Patients treated with proton therapy (n=5) did not appear to have different patterns of relapse (1 marginal, 1 distant) compared with those treated with photons or electrons (n=10; 2 distant). CONCLUSIONS: More conformal dose distribution with proton therapy does not appear to alter patterns of recurrence. Although response rates differ based on criteria by both RECIST and PERCIST assessments, the radiographic response may be slow and requires validation in other cohorts.

ABSTRACT

OBJECTIVE: To compare perioperative outcomes of the elderly versus non-elderly patients on ERPs undergoing laparotomy for gynecologic surgery. METHODS: From January 2016 to June 2017, patients undergoing elective laparotomies for gynecologic surgery were enrolled in a perioperative ERP protocol. Outcomes were compared between the elderly (age ≥ 70 years) and the non-elderly (age ≤ 69 years). Primary outcomes were length of stay and perioperative complication rates. Comparisons were performed using chi-squared tests or Fisher's exact tests for categorical data and Student's t-test or Wilcoxon rank-sum tests for continuous variables, with p < 0.05 for significance. RESULTS: One hundred eighty-nine patients were enrolled in the study, including 16 patients ≥ 70 years old. The median age was 75 years for the elderly and 45 years for the non-elderly. Elderly patients were more likely to have more complex surgery and longer operative times (absolute median difference of 39 min). Despite the increasing complexity of surgical procedures for elderly patients, there were no statistically significant differences in serious inpatient complications (Clavien-Dindo score 3A or greater), pain and nausea scores, 30-day complications and readmission rates. Elderly patients had a longer median length of stay compared to non-elderly patients by one day (p < 0.001), however, this was not statistically significant on multivariate analysis. CONCLUSION: In our series, elderly patients on the ERP had similar rates of complications and readmission when compared to non-elderly patients, despite undergoing more complex surgeries. This suggests that ERP may be feasible and safe in the elderly population undergoing elective gynecologic laparotomy.

ABSTRACT

OBJECTIVE: To compare gynecological cancer risk management between women with BRCA variants of unknown significance (VUS) to women with negative genetic testing. METHODS: Ninety-nine patients whose BRCA genetic testing yielded VUS were matched with 99 control patients with definitive negative BRCA results at a single institution. Demographics and risk management decisions were obtained through chart review. Primary outcome was the rate of risk-reducing bilateral salpingo-oophorectomy (RRBSO). Chi square tests, t-tests, and logistic regression were performed, with significance of p<0.05. RESULTS: VUS patients were more likely to be non-Caucasian (p=0.000) and of Ashkenazi-Jewish descent (p=0.000). There was no difference in gynecologic oncology referrals or recommendations to screen or undergo risk-reducing surgery for VUS vs. negative patients. Ultimately, 44 patients (22%) underwent RRBSO, with no significant difference in surgical rate based on the presence of VUS. Ashkenazi-Jewish descent was associated with a 4.5 times increased risk of RRBSO (OR=4.489; 95% CI=1.484-13.579) and family history of ovarian cancer was associated with a 2.6 times risk of RRBSO (OR=2.641; 95% CI=1.107-6.299). CONCLUSION: In our institution, patients with VUS were surgically managed similarly to those with negative BRCA testing. The numbers of patients with VUS are likely to increase with the implementation of multi-gene panel testing. Our findings underscore the importance of genetic counseling and individualized screening and prevention strategies in the management of genetic testing results.
