OBJECTIVES: To describe stage, treatment patterns, and survival for glassy cell carcinoma of the cervix (GCCC), a poorly understood rare tumor. METHODS: Clinical data and survival were compared between GCCC and more common histologic types using the National Cancer Database (NCDB) from 2004 to 2017. A retrospective review of GCCC cases at our institution from 2012 to 2020 was simultaneously performed with staging updated according to 2018 FIGO staging. Descriptive statistics and survival analyses were performed, and outcomes compared to historical references. RESULTS: 143/89,001 (0.16%) NCDB cervical cancer cases were GCCC. Compared to other histologies, GCCC cases were younger, with 74.8% diagnosed before age 50. Stage distribution was similar. Stage I cases were less commonly treated with surgery alone (19/69, 27%). 79.4% of locally advanced (stage II-IVA) cases were treated with definitive chemoradiation. GCCC demonstrated worse OS for early-stage and locally-advanced disease. No survival differences were observed for patients with stage IVB disease. Our institutional review identified 14 GCCC cases. Median age at diagnosis was 34 years. All nine early-stage cases underwent radical hysterectomy. Adjuvant radiation was given for cases meeting Sedlis criteria (4/9, 44%). All five advanced stage cases were stage IIIC and received definitive chemoradiation. Recurrence rate was 0% (0/9) for early-stage and 60% (3/5) for advanced-stage cases. 3-year PFS was 100% for early-stage and 40% for advanced-stage. 3-year OS was 100% for early-stage and 60% for advanced-stage GCCC. CONCLUSIONS: GCCC presents at earlier ages than other cervical cancer histologic types. Although NCDB showed worse OS, our more contemporary institutional review, which incorporates updated staging and newer treatment modalities found outcomes more similar to historical references of more common histologic subtypes.

OBJECTIVES: To determine whether morbid obesity should serve as an independent factor in the decision for same day discharge following minimally invasive hysterectomy. METHODS: Retrospective review was performed of patients with BMI ≥ 40 who underwent minimally invasive hysterectomy within a single comprehensive cancer center between January 2018 - August 2020. Demographics, perioperative factors, post-operative monitoring, complications, and readmissions were compared between patients who underwent same day discharge and overnight observation using Fisher's exact tests and Wilcoxon rank-sum tests. RESULTS: 374 patients with BMI ≥ 40 were included. Eighty-three (22.2%) patients underwent same day discharge, and 291 (77.8%) patients underwent overnight observation. Factors associated with increased likelihood of same day discharge included younger age (median age 53 vs 58; p = 0.001), lower BMI (median BMI 45 vs 47; p = 0.005), and fewer medical co-morbidities (Charlson Co-Morbidity Index 2 vs 3; p < 0.001). On multivariate regression analysis, frailty (OR 2.16 [1.14-4.11], p = 0.019) and surgical completion time after 12 PM (OR 3.67 [2.16-6.24], p < 0.001) were associated with increased risk of overnight observation. Few patients admitted for routine overnight observation required medical intervention (n = 14, 4.8%); most of these patients were frail (64.3%). The overall hospital readmission rate within 30 days of discharge was 3.2% (n = 12), with no patients discharged on the day of surgery being readmitted. CONCLUSIONS: Morbid obesity alone should not serve as a contraindication to same day discharge following minimally invasive hysterectomy. Admission for observation was associated with low rates of clinically meaningful intervention, and patients who underwent same day discharge were not at increased risk of adverse outcome.

OBJECTIVE: To determine the cost-effectiveness of the addition of pembrolizumab in various combinations in patients with recurrent/metastatic cervical cancer. METHODS: A decision-analysis model evaluated the cost-effectiveness of chemotherapy plus pembrolizumab and bevacizumab (CPB) relative to chemotherapy plus pembrolizumab (CP) and chemotherapy plus bevacizumab (CB) in cervical cancer patients. Data from KEYNOTE-826 was used to estimate quality-adjusted life-years (QALYs). Drug cost estimates were obtained using average wholesale prices. Incremental cost-effectiveness ratios (ICERs) were calculated to determine cost/QALY. The willingness-to-pay threshold (WTP) was set a $100,000/QALY. Sensitivity analyses were performed on cost and effectiveness for pembrolizumab-containing regimens. RESULTS: Cost of treatment with CB, CP, and CPB were $416 million (M), $713 M, and $1.51 billion, respectively. Relative to CB, the ICER for CP was $92,678. CPB was dominated. Sensitivity analyses were performed varying the cost and efficacy of CP and CPB. If overall survival (OS) with CP decreased from 24.4 months to 23.4 months, the ICER would exceed the WTP. If the OS from CP is assumed to be 20.4 months, the ICER increases to $187,746. The ICER for CP improves to $63,670 when the model is restricted to PD-L1 positive cancers. With CP eliminated, CPB becomes cost-effective relative to CB if the cost of pembrolizumab per cycle decreases from $12,080 to $2913 for the baseline model and to $4644 for the PD-L1 model. CONCLUSIONS: CP is cost-effective relative to CB for recurrent or metastatic cervical cancer. The efficacy of CPB would need to far exceed both CB and CP to be cost-effective. Restricting the model to patients with PD-L1 positive tumors dramatically improves the ICER for CP relative to CB by $30,000/QALY.

OBJECTIVE: Most women diagnosed with endometrial cancer undergo primary surgical management with hysterectomy. Although racial disparities in readmission risk following hysterectomy for non-cancerous conditions have been reported, data among women with endometrial cancer are absent. This study evaluates racial differences in readmission risk among women undergoing endometrial cancer-related hysterectomy. METHODS: In the National Cancer Database, women who underwent surgical management for endometrial cancer from 2004 to 2018 were identified. Readmission and minimally invasive hysterectomy (MIH) proportions were plotted according to year of diagnosis and race/ethnicity. Multivariable logistic regression models were used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for associations between readmission risk and epidemiological, facility, tumor, and surgical characteristics. A base model was sequentially adjusted to incorporate significant covariates. RESULTS: There were 350,631 patients included in the study. The proportion of MIH increased among all race/ethnicities over the study period; however, MIH rates were lower among Black women. Readmission proportions were 2.7% among White, 4.2% among Black, 2.9% among Hispanic, 2.4% among Asian, 2.1% among American Indian/Alaska Native, and 3.1% among Native Hawaiian/Pacific Islander women. In the fully adjusted model incorporating surgical approach, Black women (OR: 1.20, 95% CI = 1.13, 1.28) and Native Hawaiian/Pacific Islander women (OR: 1.54, 95% CI = 1.09, 2.18) were more commonly readmitted compared to White women. CONCLUSIONS: In this study, Black and Native Hawaiian/Pacific Islander women with endometrial cancer had significantly higher readmission risk than White women. Optimizing perioperative care for minority women is an essential component of overcoming racially disparate endometrial cancer outcomes.

OBJECTIVES: The routine use of upfront universal germline genetic testing among patients with newly diagnosed endometrial cancer (EC) has been proposed to improve diagnosis of Lynch syndrome (LS) and discover pathogenic variants (PVs) in other cancer susceptibility genes. We propose an algorithm prioritizing upfront multi-gene panel testing (MGPT) for newly diagnosed EC patients. METHODS: A decision analysis compared the cost of the current algorithm of universal mismatch repair (MMR) immunohistochemistry (IHC) for all EC cases to a new MGPT algorithm that employs upfront MGPT for all EC cases and reserves MMR IHC for the recurrent setting. The increase in the number of LS diagnoses using upfront MGPT, and the number of patients with PVs in BRCA1 and BRCA2 are also estimated. RESULTS: The MGPT algorithm demonstrated a cost savings of $259 per patient. Assuming 66,950 new cases of EC per year, this would represent $17.1 M of cost savings per year. When applied to all new diagnoses of EC in one year, the MGPT algorithm identified 660 (1%) additional cases of LS that would have been missed with the current algorithm. An additional 660 (1%) EC patients with BRCA1 or BRCA2 PVs would be diagnosed only through implementation of universal MGPT. CONCLUSIONS: The use of universal upfront MGPT is a practical consideration for patients with newly diagnosed EC for cost savings and improved diagnosis of highly penetrant cancer syndromes. Incorporation of germline genetic testing in the upfront setting represents an opportunity to improve access to genetic counseling and testing, and ultimately an avenue to achieve equity and improve the lives of our patients with EC and their families.

OBJECTIVE: To evaluate whether the addition of radiation to adjuvant chemotherapy is associated with improved survival in women with stage IV endometrial cancer following surgery. METHODS: The National Cancer Database (NCDB) and Surveillance, Epidemiology, and End Results Program (SEER) registries were queried for patients with stage IV endometrial cancer from 2004 to 2017. Treatment was categorized as chemotherapy alone, chemotherapy with external beam radiation therapy (EBRT), chemotherapy with vaginal brachytherapy (VBT), or chemotherapy with EBRT+VBT. Multivariable Cox regression models assessed associations between treatment modality and overall survival (OS). RESULTS: This analysis included 17,890 (NCDB: 12,812, SEER: 5078) women with stage IV endometrial cancer, including 1757 (9.8%) with IVA disease and 16,133 (90.2%) with IVB. The majority of stage IV patients received chemotherapy alone (NCDB 78.8%, SEER 77.0%). When radiation was utilized in addition to chemotherapy, EBRT was most common (NCDB 15.8%, SEER: 15.4%). In both databases, use of any radiation in addition to chemotherapy was associated with improved OS. Stage IV patients treated with chemotherapy plus EBRT had better survival than those receiving chemotherapy alone [NCDB: HR 0.75 (95% CI 0.70, 0.79), SEER: HR 0.85 (95% CI 0.77, 0.94)]. This benefit was more pronounced in patients with IVA disease [NCDB: HR 0.66 (95% CI 0.55, 0.79), SEER: HR 0.63 (95% CI 0.46, 0.85)]. In histology-stratified analyses, the addition of radiation to chemotherapy was associated with improved OS in all histologies, except clear cell. CONCLUSIONS: In this analysis of the NCDB and SEER registries, the use of multimodality treatment with radiation and chemotherapy was associated with improved OS compared to chemotherapy alone in women with stage IVA and IVB endometrial cancer.

OBJECTIVE: To determine the association of pre-treatment neutrophil-to-lymphocyte ratio (NLR) with progression-free survival (PFS) and overall survival (OS) for patients with recurrent endometrial cancer (EC) treated with immunotherapy. METHODS: Recurrent EC patients treated with immunotherapy alone or in combination from 2016 to 2021 were included. Demographics, pre-treatment laboratory results, pathologic data, response at first radiographic assessment, and cancer outcomes were obtained from the medical record. Kaplan-Meier curves were generated to compare PFS and OS stratified by NLR. RESULTS: The 106 patients included in the study were stratified by NLR <6 (n = 77, 72.6%) or NLR ≥6 (n = 29, 27.3%). Most had endometrioid pathology (59%), widely metastatic disease, and 36.8% had received ≥2 treatment lines before initiating immunotherapy. Mismatch repair deficiency (dMMR) was noted in 52 (49.1%) tumors. Most dMMR patients (94.3%) were treated with single-agent pembrolizumab, and most MMR proficient patients (78.7%) were treated with lenvatinb plus pembrolizumab. In the overall cohort, 40.2% (partial response (PR) 29.9%, complete response (CR) 10.4%) of patients with a NLR <6 responded at first radiographic assessment, compared to 31% (PR 27.5%, CR 3.4%) of patients with NLR ≥6 (p 0.691). Kaplan-Meier curves stratified by NLR <6 vs. ≥6 showed no difference in PFS. However, NLR <6 was associated with improved OS (p < 0.05). In the NLR < 6 group, the probability of survival at one year was 69% (95% CI: 58%, 82%), compared to 41% (95% CI: 26%, 67%) for the NLR > 6 group. CONCLUSIONS: Pre-treatment NLR <6 was associated with improved OS for recurrent EC patients treated with immunotherapy. NLR holds promise as a predictive biomarker for survival after immunotherapy treatment for patients with recurrent EC.

OBJECTIVES: To determine rates of surgical site infection (SSI) with and without an abdominal closure protocol for gynecologic oncology patients undergoing abdominal hysterectomy. METHODS: Consecutive patients were identified using CPT codes who underwent total abdominal hysterectomy by gynecologic oncologists at a tertiary care center from January 1, 2015 to December 31, 2019, and stratified by use of the abdominal closure protocol. Demographic, perioperative, and pathologic variables were collected. Fisher's exact and Chi squared tests were used for categorical variables, logistic regression and student t-tests for continuous variables. Multiple logistic regression was used to analyze the relationships between these variables, use of the closure protocol, and development of SSI. RESULTS: 739 patients were included over the study period (n = 393 pre-implementation, n = 346 post-implementation of the abdominal closure protocol,). Baseline demographics including ASA score, BMI, diabetes, and smoking were similar between these groups (P = 0.14-0.94). The rate of SSI within 30 days was 5.9% (23/393) in the pre-protocol group and 8.1% (28/346) under the abdominal closure protocol (P = 0.25). On univariate analysis, factors associated with SSI were BMI >40, diabetes, bowel resection, ASA score 3 or 4, hypertension, and contaminated wound class (uOR 2.31-4.09). On multivariate analysis BMI >40, diabetes, and bowel resection remained independent risk factors (aOR 2.27-2.99), with the closure protocol not achieving significance (aOR 1.43, 95% CI 0.79-2.59). There were no potentially high-risk sub-groups in whom the closing protocol showed benefit. CONCLUSION: The abdominal closure protocol in isolation did not decrease SSI in those undergoing TAH by a gynecologic oncologist.

BACKGROUND: Disparities in adjuvant treatment between Black and White women with endometrial cancer exist and contribute to worse outcomes among Black women. However, factors leading to disparate treatment receipt are understudied. OBJECTIVE: We examined whether patient refusal of adjuvant treatment (chemotherapy or radiation) differed between Black and White women and whether treatment refusal mediated racial disparities in survival among women with endometrial cancer. STUDY DESIGN: We used the National Cancer Database, a hospital-based cancer registry, to identify non-Hispanic Black and non-Hispanic White women diagnosed with endometrial cancer from 2004 to 2016 who either received or refused recommended radiation or chemotherapy. We used logistic regression to estimate multivariable-adjusted odds ratios and 95% confidence intervals for associations between race and treatment refusal. We also examined predictors of treatment refusal in race-specific models. Accelerated failure time models were used to estimate absolute differences in overall survival by race. We used causal mediation analysis to estimate the proportion of racial differences in overall survival attributable to racial differences in adjuvant treatment refusal. We considered the overall study population and strata defined by histology, and adjusted for sociodemographic, tumor, and facility characteristics. RESULTS: Our analysis included 75,447 endometrial cancer patients recommended to receive radiation and 60,187 endometrial cancer patients recommended to receive chemotherapy, among which 6.4% and 11.4% refused treatment, respectively. Among Black women recommended for radiation or chemotherapy, 6.4% and 9.6% refused, respectively. Among White women recommended for radiation or chemotherapy, 6.4% and 11.8% refused, respectively. After adjusting for sociodemographic variables, facility characteristics, and tumor characteristics, Black women were more likely to refuse chemotherapy than White women (adjusted odds ratio, 1.26; 95% confidence interval, 1.15-1.37), but no difference in radiation refusal was observed (adjusted odds ratio, 1.00; 95% confidence interval, 0.91-1.11). Some predictors of radiation refusal varied by race, namely income, education, histology, stage, and chemotherapy receipt (P interactions<.05), whereas predictors of chemotherapy refusal were generally similar between Black and White women. Among women recommended for radiation, Black women survived an average of 4.3 years shorter than White women, which did not seem attributable to differences in radiation refusal. Among women recommended for chemotherapy, Black women survived an average of 3.2 years shorter than White women of which 1.9 months (4.9%) could potentially be attributed to differences in chemotherapy refusal. CONCLUSION: We observed differences in chemotherapy refusal by race, and those differences may be responsible for up to about 2 months of the overall 3.2-year survival disparity between White and Black women. Radiation refusal did not explain any of the 4.3-year disparity among women recommended for radiation. Treatment refusal accounts for, at most, a small fraction of the total racial disparity in endometrial cancer survival. Although a better understanding of the reasons for patient treatment refusal and subsequent intervention may help improve outcomes for some women, other causes of disparate outcomes, particularly those reflecting the social determinants of health, must be investigated.

STUDY OBJECTIVE: To investigate determinants of surgical approach among women with endometrial carcinoma (EC) and associations between surgical approach and overall survival (OS). DESIGN: Retrospective cohort. SETTING: The National Cancer Database, 2010 to 2015. PATIENTS: A total of 140 470 patients with histologically confirmed EC who underwent hysterectomy. INTERVENTIONS: Patients were grouped according to surgical approach. MEASUREMENTS AND MAIN RESULTS: A total of 140 470 patients with EC were included. Robotic-assisted laparoscopy (RAL) was the most common surgical approach (48.8%), followed by laparotomy (33.6%) and traditional laparoscopy (17.6%). Use of RAL increased over the study period, and the percentages of cases managed by laparotomy decreased. Older women, those with insurance, residing in ZIP codes with lower proportions of individuals who did not graduate from high school, and those treated at noncommunity cancer programs were less likely to undergo laparotomy than RAL, and non-white women, those diagnosed with high-grade histology, and those with advanced-stage EC were more likely to undergo laparotomy than RAL. Compared with RAL, all other surgical approaches were associated with worse OS (laparotomy: hazard ratio 1.21; 95% confidence interval, 1.18-1.25; traditional laparoscopy: hazard ratio 1.06; 95% confidence interval, 1.02-1.09). Significant effect modification of the surgical approach and OS relationship according to age, race, histology, stage, and adjuvant treatment was observed. CONCLUSION: RAL increased in frequency over the study period and was associated with improved OS, supporting the continued use of RAL for EC management.

OBJECTIVE: To determine the cost-effectiveness of lenvatinib plus pembrolizumab (LP) in patients with microsatellite stable (MSS), recurrent, pretreated endometrial cancer (EC). METHODS: A decision analysis model was created to evaluate the cost-effectiveness of LP relative to doxorubicin, pegylated liposomal doxorubicin (PLD), and bevacizumab in patients with recurrent pretreated MSS EC. Published data was used to estimate quality adjusted life years (QALYs) and drug cost estimates were obtained using average wholesale prices. A health state utility (HSU) penalty of -0.10 was applied to the LP group to account for treatment toxicity. Incremental cost-effectiveness ratios (ICERs) were calculated to determine cost/QALY. The willingness to pay threshold (WTP) was set at $100,000 per QALY saved. Sensitivity analyses were performed on cost, effectiveness, and HSU penalty for LP. RESULTS: Costs of treatment with doxorubicin, PLD, and bevacizumab are $23.7 million (M), $56.9 M, and $250.8 M respectively. Cost of treatment with LP is $1.8 billion. Relative to doxorubicin, the ICERs for PLD, bevacizumab, and LP are $56,808, $345,824, and $1.6 M respectively. A sensitivity analysis varying the cost of LP shows that if the combined drug cost decreases from over $58,000 to less than $11,000 per cycle, this strategy would be cost-effective. Eliminating the HSU penalty for LP decreased the ICER $1.0 M while increasing the penalty to -0.20 increased the ICER to $3.7 M. CONCLUSIONS: LP is not cost-effective in patients with recurrent pretreated, MSS EC. A dramatic reduction in cost of LP is required for this novel strategy to be cost-effective.

OBJECTIVE: To determine associations between adoption of Medicaid expansion (ME) and changes in insurance status, early stage diagnosis, and cancer survival among women with endometrial carcinoma (EC). METHODS: The National Cancer Database (NCDB) was queried for patients diagnosed with EC between the age 40-64 from 2004 to 2015. Difference-in-differences analysis quantified the impact of ME on the proportion of new EC diagnoses with insurance (vs. uninsured), the proportion diagnosed with stage I (vs. II-IV), and overall survival. RESULTS: 156,253 patients were included. Among 65,019 women living in ME states, ME is associated with an increase in the percent of EC cases who are insured of 1.4% (95% CI 0.9-2.0%, p < 0.0001), with strongest effects among Hispanic women, women in the lowest income quartile, and women in the second age quartile (age 53-57). There was no overall impact of ME on stage, though an increase of early stage diagnoses by 2.4% (95% CI 0.3-4.5%, p = 0.022) was observed among women age 53-57. There was a trend towards improved overall survival with ME, which was strongest in women age 53-57 (HR = 0.83, 95% CI 0.70-0.99, p = 0.037). CONCLUSIONS: Among women with EC, ME positively impacted insurance coverage, an important hurdle in accessing health care. In women aged 53-57, ME was associated with earlier stage at diagnosis and improved survival, suggesting that the magnitude of the improvement in insurance coverage may correlate with important clinical outcomes. Efforts should continue to understand the complexity of barriers to health care access and to develop effective strategies to surmount them.

OBJECTIVES: Niraparib maintenance after frontline chemotherapy for advanced ovarian cancer extends progression free survival. The objective of this study was to determine the cost effectiveness of niraparib maintenance therapy in patients with newly diagnosed ovarian cancer. METHODS: Decision analysis models compared the cost of observation versus niraparib maintenance following chemotherapy for five groups: all newly diagnosed ovarian cancer patients (overall), those with homologous recombination deficiency, those harboring BRCA mutations (BRCA), homologous recombination deficiency patients without BRCA mutations (homologous recombination deficiency non-BRCA), and non-homologous recombination deficiency patients. Drug costs were estimated using average wholesale prices. Progression free survival was estimated from published data and used to estimate projected overall survival. Incremental cost effectiveness ratios per quality adjusted life year were calculated. Sensitivity analyses varying the cost of niraparib were performed. The willingness-to-pay threshold was set at US$100 000 per quality adjusted life year saved. RESULTS: For the overall group, the cost of observation was US$5.8 billion versus $20.5 billion for niraparib maintenance, with an incremental cost effectiveness ratio of $72 829. For the homologous recombination deficiency group, the observation cost was $3.0 billion versus $14.8 billion for niraparib maintenance (incremental cost effectiveness ratio $56 329). Incremental cost effectiveness ratios for the BRCA, homologous recombination deficiency non-BRCA, and non-homologous recombination deficiency groups were $58 348, $50 914, and $88 741, respectively. For the overall and homologous recombination deficiency groups, niraparib remained cost effective if projected overall survival was 2.2 and 1.5 times progression free survival, respectively. CONCLUSIONS: For patients with newly diagnosed ovarian cancer, maintenance therapy with niraparib was cost effective. Cost effectiveness was improved when analyzing those patients with homologous recombination deficiency and BRCA mutations. Efforts should continue to optimize poly-ADP-ribose polymerase utilization strategies.

OBJECTIVE: To determine the cost-effectiveness of pembrolizumab in patients with recurrent endometrial cancer that have failed first-line chemotherapy. METHODS: We created a model to evaluate the cost-effectiveness of pembrolizumab compared to pegylated liposomal doxorubicin (PLD) or bevacizumab for the treatment of women with recurrent endometrial cancer who have failed carboplatin and paclitaxel. Microsatellite instability-high (MSI-H) and non-microsatellite instability-high (non-MSI-H) tumors were evaluated. We included 4400 patients in the model; 800 patients were assumed to have MSI-H tumors. Drug costs were calculated using 2016-2017 wholesale acquisition costs, and cost of Grade III-IV toxicities was estimated from clinical experience. Effectiveness was calculated as 2-year overall survival (OS). We calculated incremental cost-effectiveness ratios (ICERs) to determine the cost per 2-year survivor. Univariate sensitivity analyses were performed. The willingness to pay threshold was $100,000 per year of OS. RESULTS: The cost of therapy with PLD and bevacizumab were $33.2 million (M) and $167.9â¯M, respectively. The cost of pembrolizumab therapy was $318.3â¯M for non-MSI-H patients compared to $57.9â¯M for MSI-H patients. For non-MSI-H patients, bevacizumab was cost-effective relative to PLD with an ICER of $153,028, while pembrolizumab was not cost-effective relative to bevacizumab with an ICER of $341,830. For MSI-H patients, pembrolizumab was cost-effective compared to PLD with an ICER of $147,249, while bevacizumab was subjected to extended dominance. Sensitivity analysis revealed that for non-MSI-H patients, one cycle of pembrolizumab would need to cost $7253 or less to be cost-effective. CONCLUSIONS: For patients with MSI-H recurrent endometrial cancers who have failed first-line chemotherapy, pembrolizumab is cost-effective relative to other single agent drugs. To be cost-effective in non-MSI-H patients, the cost of pembrolizumab should decrease substantially.

OBJECTIVE: To compare referral patterns, genetic testing and pathogenic variant rates in Black women (BW) and White women (WW) in a large academic Gynecologic Cancer Risk Assessment Clinic (GCRAC). METHODS: Cross sectional study of an IRB-approved prospective, cohort study from a GCRAC. Data evaluated included: age, race, referral provider specialty and indication, genetic testing frequency, as well as frequency and types of pathogenic variants. RESULTS: 588 WW and 57 BW were evaluated from 1/2010-12/2015. Although approximately one-third of BW and WW were referred for family history alone, referral indications varied. BW were more likely referred for a known pathogenic variant (20.0% vs. 6.2%) although less likely referred for a personal history of ovarian cancer (24.0% vs. 46.8%; pâ¯=â¯0.0023). While gynecologic oncologists referred most patients (BW 43.6% vs. WW 63.0%), BW were more likely to be referred by surgical oncologist (23.0% vs. 12.8%) or genetic counselor (12.8% vs. 5.9%) than WW (pâ¯=â¯0.0234). Referral from non-OBGYN primary care providers was <3% in both groups. Genetic testing rates were similar in both races (82.4% vs. 85.5%). Rates of BRCA1 mutations (12.7% vs. 11.5%) were similar; however, BW had more BRCA2 mutations (21.3% vs. 9.5%; pâ¯=â¯0.0194). CONCLUSIONS: Since BW are more likely to be referred by surgical oncology or genetics counselor, breast clinics might be an entry point to ensure genetic counseling and testing. Continued efforts to increase awareness regarding the importance of patient referral at the primary care level may help identify the subset of women not currently undergoing counseling and testing.

OBJECTIVES: Describe patient characteristics in African American (AA) women seen for gynecologic cancer related genetic counseling at a large southeastern comprehensive cancer center. METHODS: We reviewed an IRB approved, prospective observational cohort of patients from a Gynecologic Cancer Risk Assessment Clinic. Data evaluated included personal cancer history, family history, frequency of genetic testing, frequency/type of genetic mutations, and frequency of surgical intervention. Standard statistical statistics were utilized. RESULTS: 1227 patients were evaluated from 2003 to 2015, of which 95 (7.7%) were AA. Sixteen patients had a personal history of ovarian cancer. 21 women (22%) underwent genetic counseling only; subsequent genetic testing was not recommended based on absence of risk factors. Of the seventy-four AA patients in whom genetic testing was recommended, sixty-six (69.5%) completed testing. Of women tested, 37 (56%) had abnormal results. Eight and 14 patients had pathogenic variants in BRCA1 and BRCA2, respectively. Two were found to have pathogenic PALB2 variants; one had a pathogenic ATM variant and one constitutional MLH1 epimutation case was identified. Eleven had BRCA variants of uncertain significance. Of the patients with abnormal testing, six of 22 women with pathogenic BRCA variants underwent risk-reducing salpingo-oophorectomy (RRSO). CONCLUSIONS: Our study demonstrates that in a region where AAs represent 27% of the population, the proportion of AA patients referred to a Gynecologic Cancer Risk Assessment Clinic remains low. Pathogenic variant and variant of uncertain significance rates were high in patients tested, likely representing a selection bias of high-risk patients. Endeavors should continue to identify minorities at risk for ovarian cancer and institute measures to provide thorough genetic counseling and testing.

OBJECTIVE: To evaluate the potential relationship between outcomes in cervical cancer patients based on distance from our Comprehensive Cancer Center (CCC). METHODS: A retrospective cohort study of cervical cancer patients was performed. Abstracted data included: demographics, clinicopathologic variables, treatment, and survival. Analyses both by quartiles and distance <100 and ≥100miles from our institution were performed. Data were analyzed using SAS version 9.2. RESULTS: 390 patients living a median distance of 58.1miles (range 1.2-571miles) from our CCC were identified. Patients were generally white (n=249), non-smokers (n=226), with Stage IB disease (n=222), squamous histology (n=295) and underwent primary surgical therapy (n=229). Patients were divided into both quartiles as well as two strata: <100 and ≥100miles for comparison. Progression-free survival (PFS) and overall survival (OS) favored patients living closer to our center with a lower median OS for patients living ≥100miles (65.4vs. 99.4months; p=0.040). Cox proportional hazard modeling noted that advanced stage was predictive of inferior PFS and OS, while other clinical covariates including age, BMI, race, smoking status and histology had a variable impact on outcomes and distance >100miles was associated with a higher risk of death (hazard ratio [HR]=1.68, 95% confidence interval [CI] 1.11-2.54). CONCLUSION: Overall survival for patients living >100miles from our CCC was worse when compared to patients in closer proximity. Outreach efforts and utilization of navigators may help decrease the impact of geographic and racial disparities on outcomes.
