- Abstract
Objective: To determine the safety and feasibility of same-day discharge (SDD) following minimally invasive hysterectomy (MIH) for elderly patients and to evaluate associations between age, frailty, and postoperative outcomes., Methods: Retrospective review was conducted of patients aged ≥ 70 who underwent MIH within a single gynecologic oncology institution from 2018 to 2020. Demographics, peri -operative factors, postoperative complications, and 30-day readmission rates were collected. Frailty was determined by an 11-point modified frailty index ≥ 2. Outcomes were compared between SDD and observation groups using Fisher's exact and Wilcoxon rank-sum tests., Results: Of 169 patients included in the analysis, 8.9% (n = 15) underwent SDD, and 91.1% (n = 154) were admitted for OBS following MIH. Demographics, peri -operative factors, and frailty rates (33% SDD vs 43.5% observation; p = 0.59) were similar between groups. 86.7% (n = 13) of SDD cases were completed before 12PM, and none were completed after 6PM. No SDD patients had early post-operative complications or hospital readmissions. Early postoperative complications were diagnosed in 9 (5.8%) patients admitted for OBS, and the 30-day hospital readmission rate for patients who underwent OBS was 8.4% (n = 13). While elderly patients who met objective frailty criteria (n = 72) did not have a higher likelihood of early post-operative complications (44.4% vs 55.6%; p = 0.909), they did have a higher likelihood of ED visit within 30 days of discharge (15.3 vs 3.1%; p = 0.009), and a trend was noted toward a higher rate of 30-day hospital readmission (12.5% vs 4.1%; p = 0.080)., Conclusions: Elderly patients undergoing SDD following MIH did not have increased morbidity or mortality. Elderly patients who meet objective criteria for frailty, however, represent a more vulnerable population., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Author(s).)

- Abstract
Background: Uterine cancers are associated with a high risk for venous thromboembolisms. The American Society of Clinical Oncology practice guidelines recommend that all patients undergoing pelvic surgery for cancer should receive extended pharmacologic thromboprophylaxis with the duration being dependent on risk. However, risk stratification for patients with uterine cancer is not clearly defined. The Caprini score is the most widely used risk assessment model but it has been found to have limited use in the gynecologic oncology population. A modified Caprini score has been explored in other populations. The Khorana score is an additional risk assessment model that has not been studied in this context., Objective: Our objective was to evaluate the ability of a modified Caprini model and the Khorana score to risk stratify patients with uterine cancer for postoperative venous thromboembolisms within 90 days of surgery., Study Design: Following institutional review board approval, a retrospective cohort study was performed, and all patients with uterine cancer who underwent a hysterectomy over a 4-year period were included. The Caprini and Khorana scores were calculated for each patient. The Caprini score cutoff for highest risk was evaluated at ≥7, ≥8, and ≥9 (modified Caprini) and the Khorana score cutoff was evaluated at ≥2 and ≥3. To determine the prognostic use of each score and other clinico-pathologic criteria related to the development of a venous thromboembolism, univariate analyses were performed using independent t tests, chi-square tests, or Fisher's exact tests; a multivariate analysis was performed using logistic regression., Results: A total of 954 patients were included. The rate of venous thromboembolism development was 1.7% (16/954). A minimally invasive surgical approach was used in 90.5% (863/954) of patients. The mean Caprini score for patients with a venous thromboembolism was 10.3 compared with 8.1 for patients without a venous thromboembolism (95% confidence interval, 1.17-3.33; P<.0001). The mean Khorana score for the venous thromboembolism group was 2.4 vs 1.9 for those without (95% confidence interval, 0.04-0.82; P=.03). Both the Caprini and Khorana scores were found to be associated with venous thromboembolisms, but only a Caprini score with a cutoff of ≥8 or ≥9 was statistically significant (risk ratio, 31.25; 95% confidence interval, 1.88-519.49; risk ratio, 4.59; 95% confidence interval, 1.49-14.13, respectively), with high accuracy based on the area under the curve (0.75 and 0.68, respectively). Of the minimally invasive subgroup, 11.7% (101/863) of patients had same-day discharge with no postoperative thromboprophylaxis; none of these patients developed venous thromboembolisms. Despite extended prophylaxis among the laparotomy patients (30 days), the rate of venous thromboembolisms was more than 3 times that of the minimally invasive group (5.49% vs 1.7%). Advanced tumor stage and leukocytosis were noted to be independent risk factors for venous thromboembolisms., Conclusion: Our study suggests that using a modified Caprini score could help to identify the highest-risk patients who would benefit from prolonged thromboprophylaxis, could reduce the incidence of postoperative venous thromboembolisms, and could minimize the cost and harm of overtreatment. These findings need to be validated in a prospective manner, and further research is needed to determine the optimal duration of therapy., (Copyright © 2022 Elsevier Inc. All rights reserved.)

- Abstract
Objective: To determine the recurrence rate and survival among early-stage epithelial ovarian cancer cases considering homologous recombination deficiency (HRD) status., Methods: Single institution retrospective study of stage I/II EOC patients from 2017 to 2020. HRD was defined as evidence of germline or somatic BRCA mutation, or loss of heterozygosity (LOH)/genomic instability (GIS) as determined by companion diagnostic tests. Kaplan-Meier analyses were performed., Results: 89 stage I/II cases were included. 4/89 (4.5%) had a germline BRCA1/2 mutation, 8 (9%) were germline negative but had a somatic BRCA mutation, and 8 (9%) were BRCA wild-type but had evidence of LOH/GIS on somatic testing; these 20/89 (22%) cases comprised the HRD group. The remaining tumors were confirmed homologous recombination proficient (HRP, 35/89, 39%) or homologous recombination unknown (HRU, 34/89, 38%). The overall recurrence rate was 33/89 (37%). There were more recurrences among HRD cases (14/20, 70%) compared to HRP/HRU cases (19/69, 27.5%, p = 0.0012). Median Recurrence-Free Survival (RFS) was 35 months for HRD cases and 225 months for HRP/HRU cases (p = 0.001). At 2 years, there were 60% HRD cases and 88% HRP/HRU cases recurrence-free. At 5 years there were 29% HRD and 69% HRP/HRU cases recurrence-free (p = 0.001)., Conclusions: Despite a high rate of complete surgical staging and six cycles of adjuvant chemotherapy, recurrence rate was high in this early-stage cohort. Higher recurrence rates were seen in the HRD group, however these data are likely biased by the clinical practice of tumor testing primarily at the time of recurrence rather than the upfront setting. RFS was significantly lower for HRD cases., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: [Dr. Backes reports grants and personal fees from Clovis, Eisai, Merck, grants from Immunogen, personal fees from Agenus, AstraZeneca, Genentech, GlaxoSmithKline, all outside the submitted work.

- Abstract
Objective: Gynecologic cancers are associated with a high risk of venous thromboembolism (VTE). The Khorana score is a validated tool to assess risk of VTE in cancer patients. The purpose of this study is to determine if the Khorana score can be used as a risk stratification tool for VTE in patients with uterine cancer undergoing chemotherapy., Methods: A retrospective cohort study of patients with newly diagnosed uterine cancer receiving chemotherapy over a 4-year period was conducted. The patients were stratified based on their Khorana score as well as their chemotherapy sequence, neoadjuvant or definitive versus adjuvant., Results: A total of 276 patients were included: 40 received neoadjuvant or definitive, 236 adjuvant chemotherapy. Most patients had advanced stage disease (64.5%). 18 (6.5%) patients developed VTE within 180 days of initiating chemotherapy. High Khorana score was associated with a non-significant increase in VTE (K ≥ 2 OR 1.17, CI 0.40-3.39, K ≥ 3 OR 1.69, CI 0.61-4.69) but had poor predictive accuracy based on area under the curve (K ≥ 2 0.51, K ≥ 3 0.55). The VTE rate was higher in the neoadjuvant/definitive chemotherapy group to adjuvant (12.5% vs 5.5%, p = 0.11). While the former group had a higher average Khorana score (2.35 vs 1.93, p = 0.0048), this was not predictive of VTE., Conclusions: While validated in other cancer types, the Khorana score was found to be a poor predictor of VTE in patients with uterine cancer. The use of the Khorana score to guide routine thromboprophylaxis in these patients should be used with caution and further investigation is warranted., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Dr. Backes reports grants and personal fees from Clovis, Eisai, Merck, grants from Immunogen, personal fees from Agenus, AstraZeneca, Genentech, GlaxoSmithKline, all outside the submitted work.

- Abstract
Background: With the increasing rates of same-day discharge following minimally invasive surgery for endometrial cancer, the need for and value of routine postoperative testing is unclear., Objective: This study aimed to determine whether routine postoperative laboratory testing following minimally invasive hysterectomy for endometrial cancer leads to clinically significant changes in postoperative care., Study Design: This was a single-institution retrospective cohort study of patients undergoing minimally invasive hysterectomy for endometrial cancer by a gynecologic oncologist between June 2014 and June 2017. Patient demographics, preoperative comorbidities, operative and postoperative data, and pathologic findings were manually extracted from the patients' medical records. The financial burden of laboratory testing was computed using hospital-level cost data., Results: Of the 649 women included in the analysis, most (91.4%) were White, with a mean age of 61 years, and mean body mass index of 38.0 kg/m
2 . The most common comorbidities were diabetes mellitus (31.9%, n=207), chronic pulmonary disease (7.9%, n=51), and congestive heart failure (3.2%, n=21). Median operative time was 151 minutes (range, 61-278), and median estimated blood loss was 100 mL (range, 10-1500). Most patients (68.6%, n=445) underwent lymphadenectomy. All patients had postoperative laboratory tests ordered: 100% complete blood count, 99.7% chemistry, 62.9% magnesium, 46.8% phosphate, 37.4% calcium, and 1.2% liver function tests. Twenty-six patients (4.0%) had a change in management owing to postoperative laboratory test results. Of these 26 women, 88% experienced a change in clinical status that would have otherwise prompted testing. Only 3 (0.5% of entire cohort) were asymptomatic: 1 received a blood transfusion for asymptomatic anemia, and the other 2, who did not carry a diagnosis of diabetes mellitus, had interventions for hyperglycemia. On univariable analysis, peripheral and cerebrovascular disease, diabetes mellitus with end-organ damage, and a Charlson Comorbidity Index of ≥3 were associated with increased odds of change in management; these were not significant on multivariable analysis. Routine postoperative laboratory evaluation in this cohort increased hospital costs by $292,000., Conclusion: Routine postoperative laboratory tests are unlikely to lead to significant changes in management for women undergoing minimally invasive hysterectomy for endometrial cancer, and may increase cost without providing a discernible clinical benefit. In the setting of strict postoperative guidelines, laboratory tests should be ordered when clinically indicated rather than as part of routine postoperative management for women undergoing minimally invasive hysterectomy for endometrial cancer., (Copyright © 2022 Elsevier Inc.

- Abstract
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., (Copyright © 2022 Elsevier Inc.

- Abstract
Androgen Receptor (AR) signaling is a critical driver of hormone-dependent prostate cancer and has also been proposed to have biological activity in female hormone-dependent cancers, including type I endometrial carcinoma (EMC). In this study, we evaluated the preclinical efficacy of a third-generation AR antagonist, enzalutamide, in a genetic mouse model of EMC, Sprr2f-Cre;Pten
fl/fl . In this model, ablation of Pten in the uterine epithelium leads to localized and distant malignant disease as observed in human EMC. We hypothesized that administering enzalutamide through the diet would temporarily decrease the incidence of invasive and metastatic carcinoma, while prolonged administration would result in development of resistance and loss of efficacy. Short-term treatment with enzalutamide reduced overall tumor burden through increased apoptosis but failed to prevent progression of invasive and metastatic disease. These results suggest that AR signaling may have biphasic, oncogenic and tumor suppressive roles in EMC that are dependent on disease stage. Enzalutamide treatment increased Progesterone Receptor (PR) expression within both stromal and tumor cell compartments. Prolonged administration of enzalutamide decreased apoptosis, increased tumor burden and resulted in the clonal expansion of tumor cells expressing high levels of p53 protein, suggestive of acquired Trp53 mutations. In conclusion, we show that enzalutamide induces apoptosis in EMC but has limited efficacy overall as a single agent. Induction of PR, a negative regulator of endometrial proliferation, suggests that adding progestin therapy to enzalutamide administration may further decrease tumor burden and result in a prolonged response., (Copyright © 2020.

- Abstract
Background: Endometrial intraepithelial neoplasia, also known as complex atypical hyperplasia, is a precancerous lesion of the endometrium associated with a 40% risk of concurrent endometrial cancer at the time of hysterectomy. Although a majority of endometrial cancers diagnosed at the time of hysterectomy for endometrial intraepithelial neoplasia are low risk and low stage, approximately 10% of patients ultimately diagnosed with endometrial cancers will have high-risk disease that would warrant lymph node assessment to guide adjuvant therapy decisions. Given these risks, some physicians choose to refer patients to a gynecologic oncologist for definitive management. Currently, few data exist regarding preoperative factors that can predict the presence of concurrent endometrial cancer in patients with endometrial intraepithelial neoplasia. Identification of these factors may assist in the preoperative triaging of patients to general gynecology or gynecologic oncology., Objective: To determine whether preoperative factors can predict the presence of concurrent endometrial cancer at the time of hysterectomy in patients with endometrial intraepithelial neoplasia; and to describe the ability of preoperative characteristics to predict which patients may be at a higher risk for lymph node involvement requiring lymph node assessment at the time of hysterectomy., Materials and Methods: We conducted a retrospective cohort study of women undergoing hysterectomy for pathologically confirmed endometrial intraepithelial neoplasia from January 2004 to December 2015. Patient demographics, imaging, pathology, and outcomes were recorded. The "Mayo criteria" were used to determine patients requiring lymphadenectomy. Unadjusted associations between covariates and progression to endometrial cancer were estimated by 2-sample t-tests for continuous covariates and by logistic regression for categorical covariates. A multivariable model for endometrial cancer at the time of hysterectomy was developed using logistic regression with 5-fold cross-validation., Results: Of the 1055 charts reviewed, 169 patients were eligible and included. Of these patients, 87 (51.5%) had a final diagnosis of endometrial intraepithelial neoplasia/other benign disease, whereas 82 (48.5%) were ultimately diagnosed with endometrial cancer. No medical comorbidities were found to be strongly associated with concurrent endometrial cancer. Patients with endometrial cancer had a thicker average endometrial stripe compared to the patients with no endometrial cancer at the time of hysterectomy (15.7 mm; standard deviation, 9.5) versus 12.5 mm; standard deviation, 6.4; P = .01). An endometrial stripe of ≥2 cm was associated with 4.0 times the odds of concurrent endometrial cancer (95% confidence interval, 1.5-10.0), controlling for age. In all, 87% of endometrial cancer cases were stage T1a (Nx or N0). Approximately 44% of patients diagnosed with endometrial cancer and an endometrial stripe of ≥2 cm met the "Mayo criteria" for indicated lymphadenectomy compared to 22% of endometrial cancer patients with an endometrial stripe of <2 cm., Conclusion: Endometrial stripe thickness and age were the strongest predictors of concurrent endometrial cancer at time of hysterectomy for endometrial intraepithelial neoplasia. Referral to a gynecologic oncologist may be especially warranted in endometrial intraepithelial neoplasia patients with an endometrial stripe of ≥2 cm given the increased rate of concurrent cancer and potential need for lymph node assessment., (Copyright © 2019 Elsevier Inc.

- Abstract
Ovarian cancer is one of the most lethal gynecologic malignancies due to its rapid proliferation, frequent acquisition of chemoresistance, and widespread metastasis within the peritoneal cavity. Intraperitoneal (IP) chemotherapy has demonstrated significant anti-cancer potential but its broad clinical application is hindered by several drug delivery limitations. Herein, we engineer paclitaxel (PTX) laden hybrid microparticles (PTX-Hyb-MPs) for improved delivery of chemotherapy in ovarian cancer. The PTX-Hyb-MPs are comprised of a lipid-coated shell of poly (lactic acid-co-glycolic acid) (PLGA) encapsulating hydrophobic PTX. A co-axial electrohydrodynamic (CEH) process is used for one-step and scalable production of the PTX-Hyb-MP agent with controlled particles size, uniform size distribution, tunable thickness, and high encapsulation rate (92.17 ± 6.9%). The multi-layered structure of the PTX-Hyb-MPs is verified by transmission electron microscopy and confocal fluorescence microscopy. The effect of lipid coating on the enhancement of particle interactions with cancer cells is studied by flow cytometry and confocal fluorescence microscopy. The anti-cancer effect of the PTX-Hyb-MPs is evaluated in SKOV-3 ovarian cancer cells in vitro and a cancer xenograft model in vivo, in comparison with conventional drug delivery methods. Our studies reveal that the PTX-Hyb-MP agent can be potentially used for locoregional treatment of ovarian cancer and other tissue malignancies with sustained drug release, tunable release profiles, enhanced drug uptake, and reduced systemic toxicity., (Copyright © 2019.

- Abstract
Background: Black women with endometrial cancer are more likely to die of their disease compared with white women with endometrial cancer. These survival disparities persist even when disproportionately worse tumor characteristics among black women are accounted. Receipt of less complete adjuvant treatment among black patients with endometrial cancer could contribute to this disparity., Objective: We assessed the hypothesis that black women with endometrial cancer are less likely than their white counterparts to receive adjuvant treatment within subgroups defined by tumor characteristics in the NRG Oncology/Gynecology Oncology Group 210 Study., Study Design: Our analysis included 615 black and 4283 white women with endometrial cancer who underwent hysterectomy. Women completed a questionnaire that assessed race and endometrial cancer risk factors. Tumor characteristics were available from pathology reports and central review. We categorized women as low-, intermediate-, or high-risk based on the European Society for Medical Oncology definition. Adjuvant treatment was documented during postoperative visits and was categorized as no adjuvant treatment (54.3%), radiotherapy only (16.5%), chemotherapy only (15.2%), and radiotherapy plus chemotherapy (14.0%). We used polytomous logistic regression to estimate odds ratios and 95% confidence intervals for multivariable-adjusted associations between race and adjuvant treatment in the overall study population and stratified by tumor subtype, stage, or European Society for Medical Oncology risk category., Results: Overall, black women were more likely to have received chemotherapy only (odds ratio, 1.40; 95% confidence interval, 1.04-1.86) or radiotherapy plus chemotherapy (odds ratio, 2.01; 95% confidence interval, 1.54-2.62) compared with white women in multivariable-adjusted models. No racial difference in the receipt of radiotherapy only was observed. In tumor subtype-stratified models, black women had higher odds of receiving radiotherapy plus chemotherapy than white women when diagnosed with low-grade endometrioid (odds ratio, 2.04; 95% confidence interval, 1.06-3.93) or serous tumors (odds ratio, 1.81; 95% confidence interval, 1.07-3.08). Race was not associated with adjuvant treatment among women who had been diagnosed with other tumor subtypes. In stage-stratified models, we observed no racial differences in the receipt of adjuvant treatment. In models that were stratified by European Society for Medical Oncology risk group, black women with high-risk cancer were more likely to receive radiotherapy plus chemotherapy compared with white women (odds ratio, 1.41; 95% confidence interval, 1.03-1.94)., Conclusion: Contrary to our hypothesis, we observed higher odds of specific adjuvant treatment regimens among black women as compared with white women within specific subgroups of endometrial cancer characteristics., (Copyright © 2018 Elsevier Inc.

- Abstract
Background: There is recent evidence supporting the safety and efficacy of same-day dosing of pegfilgrastim in patients undergoing chemotherapy., Objective: To determine the cost-effectiveness of pegfilgrastim on day 1 (D1) versus day 2 (D2) for primary prevention of neutropenia in women receiving chemotherapy., Materials and Methods: A cost-utility model was designed comparing standard D2 versus D1 administration of pegfilgrastim to ovarian cancer patients receiving chemotherapy with an intermediate risk (10-15%) of febrile neutropenia (FN). Rates of FN despite prophylaxis were modeled as 10% for D1 and 5% for D2. Societal costs associated with D2 injection ($175.71) were incorporated. Quality of life (QOL) was modeled from published data; we assumed a small decrement in QOL on treatment days. Sensitivity analyses were performed., Results: D1 administration was less costly ($17,195 versus $17,681) and resulted in higher QOL (0.2298 quality adjusted life years (QALYs) versus 0.2288 QALYs) than D2. Results were sensitive to the risk of FN. D1 remained dominant or cost-effective (ICER less than $50,000/QALY) compared to D2 if the FN rate with D1 was assumed less than 14.5% (baseline estimate 10%). If the FN rate with D1 was assumed greater than or equal to 15%, D1 was not cost-effective compared to D2, with an ICER greater than $100,000/QALY. Findings are insensitive to variations in the modeled cost of treating FN, the additional cost of D2 injection, and the reduced QOL associated with treatment visits., Conclusion: Administration of D1 pegfilgrastim is cost-effective in women with ovarian cancer who are treated with intermediate risk chemotherapy., (Copyright © 2017.

- Abstract
We sought to identify how gynecologic oncologists approach reproductive counseling for their fertile, reproductive age patients, and their experience with unplanned pregnancies. Members of the Society of Gynecologic Oncology (SGO) were surveyed electronically regarding consistency of counseling patterns of contraception and fertility concerns, most and least common contraceptive methods utilized, referral patterns, and incidence of unplanned pregnancy. Of the 1424 SGO members identified, 261 participated in the questionnaire, yielding a response rate of 18%. Eighty-two percent of respondents agreed unplanned pregnancy is a potential problem, but only 57% believed their patients understood unplanned pregnancy is possible during treatment. Half of respondents report "always" in terms of frequency that contraception is addressed among their high-risk patients. After adjustment for gender, we found that the odds of reporting providing fertility counseling were nearly three times higher among attendings as compared to fellows [AOR = 2.72; 95% CI = (1.44, 5.12), three times higher in women as compared to men [AOR = 2.80; 95% CI = (1.46, 5.38)], as well as in individuals 50 + years as compared to those < 40 years old [AOR = 4.91; 95% CI = (2.05, 11.74)]. Ninety-six percent reported < 5 unplanned pregnancies, to their knowledge, in the previous five years of clinical practice. Most providers acknowledge that unplanned pregnancy is a potential risk in fertile gynecologic oncology patients, but only half believe their patients understand an unplanned pregnancy is possible. An opportunity exists to provide more directed counseling regarding fertility during and after cancer therapy, and to educate patients and providers regarding more reliable, long acting contraceptive methods.

- Abstract
Study Objective: To measure and compare postoperative pain and patient satisfaction in patients undergoing either robotic or open laparotomy for surgical staging of endometrial cancer., Design: Prospective, comparative study (Canadian Task Force classification II)., Setting: University hospital., Patients: A total of 142 patients undergoing either robotic or open laparotomy for surgical staging of endometrial cancer., Interventions: Patients scheduled for surgical staging of endometrial cancer at a single institution were identified. The patients underwent either robotic or open hysterectomy for staging of endometrial cancer. The choice of operative approach (robotic vs laparotomy) was made by the faculty physician before enrollment. Patients participated in the study for up to 48 hours for pain assessments and up to 10 ± 3 days postoperatively for quality of recovery assessments., Measurements and Main Results: The following measurements were performed: postoperative pain with the visual analog scale (VAS), 24-hour opioid consumption, and quality of recovery using the Quality of Recovery Questionnaire (QoR-40). The study was terminated owing to futility, given the lack of open procedures at our institution. Despite that lack of statistically significant difference between VAS scores at rest and with leg extension, there was a significant decrease in 24-hour opioid consumption in the robotic group. In addition, the QoR-40 showed an increased perception of recovery in patients within the robotic group compared with the laparotomy group., Conclusion: Patients with endometrial cancer who underwent robotic surgery had decreased postoperative opioid consumption and improved quality of recovery compared with those who underwent surgery via laparotomy., (Copyright © 2016 AAGL.

Clements AE, Bravo V, Koivisto C, Cohn DE, and Leone G
- Abstract
We wished to determine if WWP2 gene expression and PTEN protein levels inversely correlate in human endometrial cancer tissues. Fifty-one endometrioid endometrial tumors and five normal endometrial controls were available for analysis. PTEN protein levels were assessed by immunohistochemistry (IHC). WWP2 and PTEN gene expression were quantitated by RT PCR. Clinical and pathologic information was collected by chart review. We found that in tumors with low PTEN protein but normal mRNA expression there were significantly higher levels of WWP2 expression (p = 0.0017). Increased WWP2 expression was not associated with clinical prognostic factors including lymphovascular space invasion, ≥ 50% myometrial invasion, grade, stage or recurrence. WWP2 expression was not different statistically between tumors and normal controls (p = NS). Therefore, in this cohort, tumors with low PTEN protein but normal mRNA expression had elevated levels of WWP2 expression. This suggests that WWP2 may be playing a role in PTEN degradation in endometrial cancer.

- Abstract
Objective: To estimate the rate of inpatient stay and the factors predicting inpatient status after robotic surgery for endometrial cancer following the change in the Medicare definition of "inpatient" to include hospitalization spanning 2 midnights., Design: Retrospective chart review (Canadian Task Force classification II-1)., Setting: Academic hospital., Patients: All patients (n = 395) with endometrial cancer who underwent robotic surgical management between 2006 and 2010., Intervention: The outpatient stay group with hospitalization spanning 1 midnight was compared with the inpatient stay group with hospitalization spanning 2 midnights or longer through estimation of the adjusted relative risk (aRR) for various characteristics of interest., Results: Ninety-six of 395 patients (24.3%) stayed at least 2 midnights and thus were deemed inpatients. Clinical factors associated with inpatient stay were increasing age, history of myocardial infarction (aRR, 2.0; 95% confidence interval [CI], 1.0-3.7), surgery start time at or after 12 noon (aRR, 1.7; 95% CI, 1.2-2.4), perioperative blood transfusion (aRR, 3.2; 95% CI, 2.3-4.5), and surgery performed in the year 2010 (aRR, 0.5; 95% CI, 0.3-0.7). Age ≥ 60 years was associated with at least a 2-fold adjusted risk of prolonged hospitalization. Body mass index, other medical comorbidities, operative duration, estimated blood loss, and performance of lymphadenectomy or additional surgical procedures were not identified as significant risk factors., Conclusion: Approximately 75% of the patients undergoing robotic surgery for endometrial cancer were discharged as outpatients. Recognition of factors predicting inpatient stay can improve hospital resource allocation and throughput in women undergoing robotic surgery for endometrial cancer., (Copyright © 2015 AAGL.

- Abstract
Background: Inflammation may be important in endometrial cancer development. Long-chain ω-3 (n-3) polyunsaturated fatty acids (LCω-3PUFAs) may reduce inflammation and, therefore, reduce cancer risk. Because body mass is associated with both inflammation and endometrial cancer risk, it may modify the association of fat intake on risk., Objective: We examined whether intakes of LCω-3PUFAs were associated with endometrial cancer risk overall and stratified by body size and histologic subtype., Design: Women were n = 87,360 participants of the Women's Health Initiative Observational Study and Clinical Trials who were aged 50-79 y, had an intact uterus, and completed a baseline food-frequency questionnaire. After 13 y of follow-up, n = 1253 incident invasive endometrial cancers were identified. Cox regression models were used to estimate HRs and 95% CIs for the association of intakes of individual ω-3 fatty acids and fish with endometrial cancer risk., Results: Intakes of individual LCω-3PUFAs were associated with 15-23% linear reductions in endometrial cancer risk. In women with body mass index (BMI; in kg/m(2)) <25, those in the upper compared with lowest quintiles of total LCω-3PUFA intake (sum of eicosapentaenoic, docosapentaenoic, and docosahexaenoic acids) had significantly reduced endometrial cancer risk (HR: 0.59; 95% CI: 0.40, 0.82; P-trend = 0.001), whereas there was little evidence of an association in overweight or obese women. The reduction in risk observed in normal-weight women was further specific to type I cancers., Conclusions: Long-chain ω-3 intake was associated with reduced endometrial cancer risk only in normal-weight women. Additional studies that use biomarkers of ω-3 intake are needed to more accurately estimate their effects on endometrial cancer risk. This trial was registered at clinicaltrials.gov as NCT00000611., (© 2015 American Society for Nutrition.)

- Abstract
Background: Inflammation plays an important role in endometrial cancer etiology. Long-chain ω-3 (n-3) polyunsaturated fatty acids (PUFAs), derived from marine sources, are thought to be antiinflammatory; however, several studies of fish consumption suggest an increase in risk., Objective: This study examined whether intakes of long-chain ω-3 PUFAs, including eicosapentaenoic acid (EPA; 20:5ω-3) and docosahexaenoic acid (DHA; 22:6ω-3), from diet and supplements and intake of fish are associated with endometrial cancer risk., Design: Between 2000 and 2002, 22,494 women aged 50-76 y, living in western Washington State, were recruited to the VITamins And Lifestyle cohort study. Incident endometrial cancers (n = 263) were identified through the Surveillance, Epidemiology, and End Results cancer registry after 9 y of follow-up. Multivariable-adjusted HRs and 95% CIs for the association of intakes of individual long-chain ω-3 PUFAs and fish with endometrial cancer risk were estimated by using Cox proportional hazards., Results: Women in the highest compared with the lowest quintile of dietary EPA + DHA intake had a 79% increased risk of endometrial cancer (95% CI: 16%, 175%; P-trend = 0.026). Results were similar for EPA and DHA measured individually and for fish intake. When data were stratified by body mass index (in kg/m²; <25 or ≥ 25), increases in risk of long-chain ω-3 PUFAs were restricted to overweight and obese women, and statistically significant reductions in risk were observed for normal-weight women., Conclusions: The overall increased risk reported here confirms the findings of several prior observational studies of fish intake, which observed similar increases in risk. Randomized trials are needed to confirm these findings.

- Abstract
A major mechanism of DNA repair related to homologous recombination is the Fanconi anemia (FA) pathway. FA genes collaborate with BRCA genes to form foci of DNA repair on chromatin after DNA damage or during the S phase of the cell cycle. Our goal was to develop a method capable of evaluating the functional status of the pathway in patients' tumor tissue, which could also be practically incorporated into large-scale screening. To develop this method, we first used Western immunoblot to detect FANCD2 protein monoubiquitination in fresh tumor specimens of patients with ovarian cancer undergoing surgery and stained formalin-fixed paraffin-embedded tumor tissue simultaneously with 4',6-diamidino-2-phenylindole, FANCD2, and Ki67 antibodies, eventually extending this method to other solid tumors. This triple stain permitted evaluation of the presence, or lack thereof, of FANCD2 subnuclear repair foci in proliferating cells by immunofluorescence microscopy. Overall, we evaluated 156 formalin-fixed paraffin-embedded tumor samples using the FA triple-staining immunofluorescence method. The ratios of FANCD2 foci-negative tumors in ovarian, lung, and breast tumor samples were 21%, 20%, and 29.4%, respectively. Our studies have led to the development of a suitable method for screening, capable of identifying tumors with somatic functional defects in the FA pathway. The use of paraffin-embedded tissues renders the reported method suitable for large-scale screening to select patients for treatment with DNA interstrand crosslinking agents, poly ADP-ribose polymerase inhibitors, or their combination., (Copyright © 2013 Mosby, Inc.

- Abstract
Purpose: Lynch syndrome accounts for 2-5% of endometrial cancer cases. Lynch syndrome prediction models have not been evaluated among endometrial cancer cases., Methods: Area under the receiver operating curve (AUC), sensitivity and specificity of PREMM(1,2,6), MMRpredict, and MMRpro scores were assessed among 563 population-based and 129 clinic-based endometrial cancer cases., Results: A total of 14 (3%) population-based and 80 (62%) clinic-based subjects had pathogenic mutations. PREMM(1,2,6), MMRpredict, and MMRpro were able to distinguish mutation carriers from noncarriers (AUC of 0.77, 0.76, and 0.77, respectively), among population-based cases. All three models had lower discrimination for the clinic-based cohort, with AUCs of 0.67, 0.64, and 0.54, respectively. Using a 5% cutoff, sensitivity and specificity were as follows: PREMM(1,2,6), 93% and 5% among population-based cases and 99% and 2% among clinic-based cases; MMRpredict, 71% and 64% for the population-based cohort and 91% and 0% for the clinic-based cohort; and MMRpro, 57% and 85% among population-based cases and 95% and 10% among clinic-based cases., Conclusion: Currently available prediction models have limited clinical utility in determining which patients with endometrial cancer should undergo genetic testing for Lynch syndrome. Immunohistochemical analysis and microsatellite instability testing may be the best currently available tools to screen for Lynch syndrome in endometrial cancer patients.

- Abstract
Objective: We sought to determine a microRNA (miRNA) profile of surgically staged endometrial cancers., Study Design: RNA was extracted from archival primary endometrial cancers, and an miRNA profile was established using a microarray and confirmed with real-time polymerase chain reaction. Targets of differentially expressed miRNAs were explored using real-time polymerase chain reaction and Western blot in endometrial cell lines., Results: Endometrial cancer has an miRNA profile distinct from normal endometrium, even in patients with stage IA grade 1 tumors. This miRNA cancer profile was able to correctly assign a specimen as a malignancy with a sensitivity of 92%. Overexpressed miRNAs were predicted to target PTEN, and transfection of cell lines with these miRNAs led to down-regulation of PTEN expression. In advanced disease, an miRNA pattern distinct from early-stage disease was seen, and overexpression of mir-199c predicted improved cancer survival in this population., Conclusion: Endometrial cancer has a distinct miRNA profile, and miRNAs can be used as a predictive biomarker., (Copyright 2010 Mosby, Inc.

- Abstract
Objective: Our purpose is to describe and demonstrate basic console dissection techniques in robotic hysterectomy, aortic and pelvic lymphadenectomy for endometrial carcinoma, and efficient methods to direct the assistant., Methods: The operating room and patient are prepared as previously detailed. Adequate exposure is the key to a successful procedure, and a skilled bedside assistant is essential in developing the dissection. Clear communication between the console surgeon and assistant plays a critical role. In addition, proper use of the robotic fourth arm allows additional retraction and permits smooth case progression., Results: We have completed more than 120 robotic hysterectomies, pelvic-aortic lymphadenectomies for endometrial cancer with these key steps., Conclusions: A systematic routine and effective use of the bedside assistant is essential for successfully completing robotic hysterectomy and aortic and pelvic lymphadenectomy. This manuscript and video illustrates our method emphasizing an efficient and comprehensive technique for this procedure., (Copyright 2010 AAGL. Published by Elsevier Inc. All rights reserved.)

- Abstract
Objective: The objective of this study was to compare the prevalence of cyclooxygenase-2 (COX-2), aromatase, and hormone receptor immunohistochemical (IHC) expression to well defined clinical-pathologic prognostic factors in a large group of surgically staged endometrial cancer patients., Study Design: A tissue microarray (TMA) was constructed from 336 separate specimens of endometrial cancer. IHC was performed for estrogen (ER) and progesterone (PR) receptor, COX-2, COX-1, and aromatase., Results: The majority of tumors expressed COX-2 (59%) and aromatase (65%). COX-2 staining significantly correlated with aromatase expression ( P < .014) but did not correlate with ER and PR. COX-2 expression was correlated with worsening histologic grade ( P < .026) and approached statistical significance for deep myometrial invasion ( P < .055). After applying multivariate analysis, no single IHC or combination of IHCs correlated with intrauterine poor prognostic factors or advanced stage. Only myometrial invasion >50% (OR 6.98, P < .001) and nonendometrioid histology (OR 4.933, P < .001) were predictive of advanced stage after multivariate analysis., Conclusion: COX-2 and aromatase are expressed in the majority of endometrial cancer patients. COX-2 expression was not associated with the great majority of surgical-pathologic prognostic factors. COX-2 expression did significantly correlate with aromatase expression, suggesting that intratumoral production of estrogen in endometrial cancer may be an important mechanism in tumorigenesis.

- Abstract
Objective: We tested the hypothesis that local anesthetic that is injected before a vertical midline abdominal incision would decrease the use of postoperative opioids., Study Design: Patients who would undergo abdominal surgical procedures with general anesthesia by a planned vertical midline incision were enrolled in the study. Patients were assigned randomly to receive either 0.5% ropivacaine or normal saline solution placebo that was injected in the subcuticular tissue and fascia before the incision of each. All patients received morphine after the operation with a patient-controlled analgesia device. Morphine consumption was measured during the postoperative period at intervals of 0 to 6 hours, 6 to 12 hours, 12 to 24 hours, and 24 to 48 hours. Postoperative pain was assessed at 6, 12, 24, and 48 hours after the conclusion of the procedure with a visual analog scale., Results: Eighty-four patients were enrolled in the study; 16 patients were excluded; therefore, 68 patients had useable data. The two treatment groups did not differ in age, height, weight, the length of the operation, the length of the incision, the position of the incision, the placement of drains, or the procedure that was performed. There was no significant difference in morphine consumption for any of the four intervals. The visual analog scale was not significantly different between the two groups at 6, 12, or 24 hours after operation. The visual analog scale at 48 hours was lower in the group that received ropivacaine (2.69 vs 4.26, P =.02). Data were analyzed by the Student t test., Conclusion: Pre-emptive analgesia with 0.5% ropivacaine given before skin incision does not decrease the postoperative analgesic use in patients who undergo laparotomy by a midline vertical skin incision.
