Lunchbox trial: A randomized phase III trial of cisplatin and irradiation followed by carboplatin and paclitaxel versus sandwich therapy of carboplatin and paclitaxel followed by irradiation then carboplatin and paclitaxel for advanced endometrial carcinoma.

BACKGROUND: The objective was to compare sequencing strategies for treatment of advanced endometrial carcinoma. METHODS: Patients were eligible if they had FIGO 2009 Stage III or IVA endometrial carcinoma or Stage I or II serous or clear cell endometrial carcinoma and positive cytology. Patients were randomized to: Cisplatin 50 mg/m2 IV Days 1 and 29 plus radiation followed by Carboplatin AUC 5 or 6 plus Paclitaxel 175 mg/m2 q 21 days for 4 cycles (chemoRT then chemo) vs. Carboplatin AUC 6 plus Paclitaxel 175 mg/m2 q 21 days for 3 cycles followed by radiation followed by Carboplatin AUC 5 or 6 plus Paclitaxel 175 mg/m2 q 21 days for 3 cycles (sandwich therapy). Futility analysis was planned. The primary objective was to determine if chemoRT then chemo improves recurrence-free survival (RFS) compared to sandwich therapy. RESULTS: Of the 48 patients enrolled at 8 sites, 42 patients were eligible for futility analysis, and the trial was closed early. The median follow-up was 30.9 months. The 3-year RFS was 85.7% (95% confidence interval [CI], 62 to 95) in the chemoRT then chemo arm and 73.4% (95% CI, 43 to 89) in the sandwich therapy group (p = 0.58). The 3-year overall survival (OS) was 88.4% (95% CI, 61 to 97) in the chemoRT then chemo arm and 80.9% (95% CI, 51 to 93) in the sandwich therapy group (p = 0.55). CONCLUSION: There was no observed significant difference between chemoRT then chemo compared to sandwich therapy in terms of RFS, OS, or adverse events, although the trial was underpowered and closed early due to low accrual.

Underrepresentation of racial and ethnic minority groups in gynecologic oncology: An analysis of over 250 trials.

OBJECTIVE: To describe the participation of racial and ethnic minority groups (REMGs) in gynecologic oncology trials. METHODS: Gynecologic oncology studies registered on ClinicalTrials.gov between 2007 and 2020 were identified. Trials with published results were analyzed based on reporting of race/ethnicity in relation to disease site and trial characteristics. Expected enrollment by race/ethnicity was calculated and compared to actual enrollment, adjusted for 2010 US Census population data. RESULTS: 2146 gynecologic oncology trials were identified. Of published trials (n = 252), 99 (39.3%) reported race/ethnicity data. Recent trials were more likely to report these data (36% from 2007 to 2009; 51% 2013-2015; and 53% from 2016 to 2018, p = 0.01). Of all trials, ovarian cancer trials were least likely to report race/ethnicity data (32.1% vs 39.3%, p = 0.011). Population-adjusted under-enrollment for Blacks was 7-fold in ovarian cancer, Latinx 10-fold for ovarian and 6-fold in uterine cancer trials, Asians 2.5-fold in uterine cancer trials, and American Indian and Alaska Native individuals 6-fold in ovarian trials. Trials for most disease sites have enrolled more REMGs in recent years - REMGs made up 19.6% of trial participants in 2007-2009 compared to 38.1% in 2016-2018 (p < 0.0001). CONCLUSION: Less than half of trials that published results reported race/ethnicity data. Available data reveals that enrollment of REMGs is significantly below expected rates based on national census data. These disparities persisted even after additionally adjusting for population size. Despite improvement in recent years, additional recruitment of REMGs is needed to achieve more representative and equitable participation in gynecologic cancer clinical trials.

Vulvar Cancer, Version 3.2024, NCCN Clinical Practice Guidelines in Oncology.

Vulvar cancer is annually diagnosed in an estimated 6,470 individuals and the vast majority are histologically squamous cell carcinomas. Vulvar cancer accounts for 5% to 8% of gynecologic malignancies. Known risk factors for vulvar cancer include increasing age, infection with human papillomavirus, cigarette smoking, inflammatory conditions affecting the vulva, and immunodeficiency. Most vulvar neoplasias are diagnosed at early stages. Rarer histologies exist and include melanoma, extramammary Paget's disease, Bartholin gland adenocarcinoma, verrucous carcinoma, basal cell carcinoma, and sarcoma. This manuscript discusses recommendations outlined in the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for treatments, surveillance, systemic therapy options, and gynecologic survivorship.

A non-comparative, randomized, phase II trial of atezolizumab or atezolizumab plus tiragolumab for programmed death-ligand 1-positive recurrent cervical cancer (SKYSCRAPER-04).

OBJECTIVE: To evaluate tiragolumab (anti-TIGIT) and atezolizumab (anti-PD-L1) as second- or third-line therapy for PD-L1-positive persistent/recurrent cervical cancer. METHODS: In the open-label, non-comparative, randomized phase II SKYSCRAPER-04 trial (NCT04300647), patients with PD-L1-positive (SP263 tumor area positivity ≥5%) recurrent/persistent cervical cancer after 1-2 chemotherapy lines (≥1 platinum-based) were randomized 3:1 to atezolizumab 1200 mg with/without tiragolumab 600 mg every 3 weeks until disease progression or unacceptable toxicity. Stratification factors were performance status, prior (chemo)radiotherapy, and disease status. The primary endpoint was independent review committee-assessed confirmed objective response rate per RECIST v1.1 in patients receiving tiragolumab plus atezolizumab. An objective response rate ≥21% (one-sample z-test p≤0.0245) was required for statistical significance versus a historical reference. RESULTS: Protocol-defined independent review committee-assessed objective response rates were 19.0% (95% CI 12.6 to 27.0) in 126 patients receiving tiragolumab plus atezolizumab (p=0.0787 vs historical reference) and 15.6% (95% CI 6.5 to 29.5) in 45 atezolizumab-treated patients. Response rates were higher in PD-L1high (tumor area positivity ≥10%) than PD-L1low (tumor area positivity 5%-9%) subgroups with both regimens. At 8.5 months' median follow-up, independent review committee-assessed progression-free survival was 2.8 months (95% CI 1.7 to 4.1) with tiragolumab plus atezolizumab and 1.9 months (95% CI 1.5 to 3.0) with atezolizumab. In post hoc analyses (10.4 months' median follow-up), median overall survival was 11.1 months (95% CI 9.6 to 14.5) with the combination and 10.6 months (95% CI 6.9 to 13.8) with atezolizumab (crossover permitted). In the combination group, 3% of patients had adverse events requiring treatment discontinuation and 8% had grade ≥3 adverse events of special interest; corresponding values in the single-agent arm were 4% and 11%. There were no treatment-related deaths or new safety findings. CONCLUSION: The objective response rate with the tiragolumab-plus-atezolizumab combination was numerically higher than the historical reference but did not reach statistical significance.

A review of the state of cervical cancer: updates from prevention to recurrent disease.

PURPOSE OF REVIEW: To summarize the recent updates in cervical cancer from prevention and early detection to the management of early stage and recurrent disease as well as future areas of exploration. RECENT FINDINGS: The importance of the human papilloma virus vaccine and screening continue to make an impact in reducing the global burden of cervical cancer. In early-stage, low risk disease, new studies have demonstrated the role of less radical surgery with similar disease related outcomes. Efforts to improve outcomes in locally advanced cervical cancer have been reported. The incorporation of adjuvant chemotherapy, novel agents and checkpoint inhibitors, with the latter impacting disease free survival. In advanced/recurrent disease, the role of immunotherapy continues to make an impact and, in addition to recurrent disease, has now moved to the frontline for patients with programmed cell death ligand 1 expression. Tisotumab vedotin, an antibody drug conjugate, and other novel agents continue to be studied in this setting. SUMMARY: In this review, we discuss prevention measures and the outcomes of recent trials in all stages of cervical cancer. As therapies continue to evolve, ongoing trials and new areas of exploration will continue to identify opportunities to improve survival in cervical cancer.

Pathologic response to neoadjuvant chemotherapy in ovarian cancer and its association with outcome: A surrogate marker of survival.

OBJECTIVE: We aimed to validate whether pathologic response (pR) to neoadjuvant chemotherapy (NACT) using a three-tier chemotherapy response score (CRS) is associated with clinical outcome in ovarian cancer (OC) and could be used as surrogate marker for survival. METHODS: We conducted a retrospective study of OC patients with FIGO stage III/IV disease who received NACT and graded response as no or minimal (CRS 1), partial (CRS 2), or complete/near-complete (CRS 3) pR using tissue specimens obtained from omentum. Uni- and multivariate survival analyses were performed accounting for age, FIGO stage, debulking and BRCA status as well as neoadjuvant use of bevacizumab. RESULTS: CRSs 1, 2 and 3 were found in 41(31%), 62 (47%) and 30 (22%) of the 133 examined cases. Response to NACT was associated with significantly improved progression-free (PFS, p < 0.001) and overall survival (OS, p = 0.011). Complete/ near-complete pathologic response (CRS3) was associated with improved PFS (median 24.8 vs. 12.5 months, unadjusted HR 0.28 [95%CI 0.15-0.54], p < 0.001; adjusted hazard ration (aHR) 0.31 [95% CI 0.14-0.72], p = 0.007) and OS (median 63.3 vs. 32.1 months, unadjusted HR 0.27 [95%CI 0.10-0.68], p = 0.006; aHR 0.32 [95% CI 0.09-1.11], p = 0.072) when compared to no or minimal response (CRS1). CONCLUSIONS: We validate a three-tier CRS for assessment of pathologic response to NACT in OC and demonstrate its prognostic independence of BRCA status or neoadjuvant bevacizumab use. Improving pR rates may be a useful goal of NACT in OC with the expectation of improved survival. The CRS may be a useful endpoint in clinical trials in OC.

Safety and feasibility of same-day discharge following minimally invasive hysterectomy in the morbidly obese patient population.

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.

TP53 mutation and abnormal p53 expression in endometrial cancer: Associations with race and outcomes.

OBJECTIVE: This multi-center cohort study assessed associations between race, TP53 mutations, p53 expression, and histology to investigate racial survival disparities in endometrial cancer (EC). METHODS: Black and White patients with advanced or recurrent EC with Next Generation Sequencing data in the Endometrial Cancer Molecularly Targeted Therapy Consortium database were identified. Clinicopathologic and treatment variables were summarized by race and compared. Overall survival (OS) and progression-free survival (PFS) among all patients were estimated by the Kaplan-Meier method. Cox proportional hazards models estimated the association between race, TP53 status, p53 expression, histology, and survival outcomes. RESULTS: Black patients were more likely than White patients to have TP53-mutated (N = 727, 71.7% vs 49.7%, p < 0.001) and p53-abnormal (N = 362, 71.1% vs 53.2%, p = 0.003) EC. Patients with TP53-mutated EC had worse PFS (HR 2.73 (95% CI 1.88-3.97)) and OS (HR 2.20 (95% CI 1.77-2.74)) compared to those with TP53-wildtype EC. Patients with p53-abnormal EC had worse PFS (HR 2.01 (95% CI 1.22-3.32)) and OS (HR 1.61 (95% CI 1.18-2.19)) compared to those with p53-wildtype EC. After adjusting for TP53 mutation and p53 expression, race was not associated with survival outcomes. The most frequent TP53 variants were at nucleotide positions R273 (n = 54), R248 (n = 38), and R175 (n = 23), rates of which did not differ by race. CONCLUSIONS: Black patients are more likely to have TP53-mutated and p53-abnormal EC, which are associated with worse survival outcomes than TP53- and p53-wildtype EC. The higher frequency of these subtypes among Black patients may contribute to survival disparities.

Less is more: clinical utility of postoperative laboratory testing following minimally invasive hysterectomy for endometrial cancer.

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/m2. 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.

Uterine Neoplasms, Version 1.2023, NCCN Clinical Practice Guidelines in Oncology.

Adenocarcinoma of the endometrium (also known as endometrial cancer, or more broadly as uterine cancer or carcinoma of the uterine corpus) is the most common malignancy of the female genital tract in the United States. It is estimated that 65,950 new uterine cancer cases will have occurred in 2022, with 12,550 deaths resulting from the disease. Endometrial carcinoma includes pure endometrioid cancer and carcinomas with high-risk endometrial histology (including uterine serous carcinoma, clear cell carcinoma, carcinosarcoma [also known as malignant mixed Müllerian tumor], and undifferentiated/dedifferentiated carcinoma). Stromal or mesenchymal sarcomas are uncommon subtypes accounting for approximately 3% of all uterine cancers. This selection from the NCCN Guidelines for Uterine Neoplasms focuses on the diagnosis, staging, and management of pure endometrioid carcinoma. The complete version of the NCCN Guidelines for Uterine Neoplasms is available online at NCCN.org.

Sentinel lymph node mapping for endometrial cancer: Opportunity for medical waste reform.

OBJECTIVE: As healthcare expenditures continue to rise, identifying mechanisms to reduce unnecessary costs is critical. The objective of this study is to estimate the annual cost of wasted indocyanine green (ICG) used for sentinel lymph node mapping in patients with endometrial cancer. METHODS: Using the Surveillance, Epidemiology, and End Results program database and Premier database, we determined the annual number of cases in which sentinel lymph node mapping with ICG would be used and the median cost of ICG to institutions and patients, respectively. We assumed that gynecologic oncologists use 2-4 mL (20-40%) of the currently available ICG vial kit (25 mg per 10 mL) per case. Estimated waste was then calculated using cost as a measure of institutional waste and charge as excess cost transferred to patients or payers. RESULTS: An estimated 45,864 cases of localized endometrial cancer were identified and eligible for sentinel lymph node (SLN) mapping. The mean total cost associated with ICG was 99.20 and the mean charge was $483.64. The estimated excess annual cost to hospitals was $2,729,825 to $3,639,767. Similarly, using mean charge data, the annual cost of wasted drug for patients and payers was $13,308,999 to $17,745,332. CONCLUSIONS: The annual cost of wasted ICG due to its current manufactured vial size exceeds $2 million for hospitals and $13.3-$17.7 million for patients. We suggest ICG vials should be packaged in a 10 mg vial kit (2-4 mL sterile solution) to avoid drug waste and the financial impact to institutions and patients.

Who will be readmitted? Evaluation of the laparoscopic hysterectomy readmission score in a gynecologic oncology population undergoing robotic-assisted hysterectomy.

OBJECTIVES: The laparoscopic hysterectomy readmission score (LHRS) was created to identify patients for whom same day discharge (SDD) after minimally invasive hysterectomy (MIH) may not be advisable and includes diabetes, chronic obstructive pulmonary disease, disseminated cancer, chronic steroid use, bleeding disorder, length of surgery, and any postoperative complication prior to discharge. We evaluated the performance of the score at predicting readmission in a gynecologic oncology population, and additionally sought to determine if any factors known prior to surgery could replace those that are not known until the time of surgery (operative time and postoperative complication). METHODS: This was a single-institution retrospective cohort study of women undergoing robotic hysterectomy by a gynecologic oncologist in 2018. Associations between pre-operative, operative and post-operative factors and 30-day readmission, SDD and postoperative complications were assessed using logistic regression. RESULTS: The 30-day readmission rate among the 423 women in the cohort was 4.5% and 1.9% in those undergoing SDD. Readmission rates by LHRS were: score 1 (4.9%), score 2 (7.8%), score 3 (13.6%), score 4 (16.7%). Patients with a LHRS of ≥3 had higher odds of readmission compared to those with a lower score (OR 4.20, p = 0.02). Infectious morbidity accounted for the majority of postoperative complications, emergency room visits and readmissions. We did not identify preoperative factors to replace the intra- and post-operative factors used in the score. CONCLUSIONS: The readmission rate following MIH is low, and a LHRS of ≥3 is associated with increased risk of readmission. Our findings support the applicability of the LHRS to a gynecologic oncology population; addressing risk factors for postoperative infection or closer follow up for patients with a LHRS ≥3 could reduce postoperative readmissions.

Implicit biases in healthcare: implications and future directions for gynecologic oncology.

Health disparities have been found among patients with gynecologic cancers, with the greatest differences arising among groups based on racial, ethnic, and socioeconomic factors. Although there may be multiple social barriers that can influence health disparities, another potential influence may stem from healthcare system factors that unconsciously perpetuate bias toward patients who are racially and socioeconomically disadvantaged. More recent research suggested that providers hold these implicit biases (automatic and unconscious attitudes) for stigmatized populations with cancer, with emerging evidence for patients with gynecologic cancer. These implicit biases may guide providers' communication and medical judgments, which, in turn, may influence the patient's satisfaction with and trust in the provider. This narrative review consolidated the current research on implicit bias in healthcare, with a specific emphasis on oncology professionals, and identified future areas of research for examining and changing implicit biases in the field of gynecologic oncology.

Frailty is independently associated with worse outcomes and increased resource utilization following endometrial cancer surgery.

OBJECTIVE: Frailty has been associated with poorer surgical outcomes and is a critical factor in procedural risk assessment. The objective of this study is to assess the impact of frailty on surgical outcomes in patients with endometrial cancer. METHODS: Patients undergoing inpatient gynecologic surgery for endometrial cancer were identified using the 2005-2017 Nationwide Inpatient Sample database. The Johns Hopkins Adjusted Clinical Groups frailty-defining diagnosis indicator was used to designate frailty. Multivariate regression models were used to assess the association of frailty with postoperative outcomes and resource use. RESULTS: Of 339 846 patients, 2.9% (9868) were considered frail. After adjusting for patient and hospital characteristics, frailty was associated with a four-fold increase in inpatient mortality (adjusted OR (aOR) 4.1; p<0.001), non-home discharge (aOR 5.2; p<0.001), as well as increased respiratory (aOR 2.6; p<0.001), neurologic (aOR 3.3; p<0.001), renal (aOR 2.0; p<0.001), and infectious (aOR 3.2; p<0.001) complications. While frail patients exhibited increased mortality with age, the rate of mortality in this cohort decreased significantly over time. Compared with non-frail counterparts, frail patients had longer lengths of stay (7.6 vs 3.4 days; p<0.001) and increased hospitalization costs with surgical admission ($25 093 vs $13 405; p<0.001). CONCLUSIONS: Frailty is independently associated with worse surgical outcomes, including increased mortality and resource use, in women undergoing surgery for endometrial cancer. Though in recent years there have been improvements in mortality in the frail population, further efforts to mitigate the impact of frailty should be explored.

The increasing incidence of stage IV cervical cancer in the USA: what factors are related?

OBJECTIVE: Cervical cancer (International Federation of Gynecology and Obstetrics (FIGO)) stage IVA-B (distant stage) is a rare diagnosis with an approximate 5 year survival rate of 17% and with limited treatment options. The objective of this study was to determine the trends in distant stage cervical cancer in the USA and identify possible factors related to these trends. METHODS: Data were obtained from the United States Cancer Statistics program from 2001 to 2018. Rates of cervical cancer screening and vaccination were evaluated using the Behavioral Risk Factor Surveillance System and TeenVaxView. SEER*Stat 8.3.8.9.2 and Joinpoint regression program 4.9.0.0 were used to calculate incidence trends. RESULTS: Over the last 18 years, 29 715 women were diagnosed with distant stage cervical carcinoma. Black women have disproportionately higher rates at 1.55/100 000 versus 0.92/100 000 in White women (p<0.001). When examining the trends over time, there has been an annual increase in distant stage cervical cancer at a rate of 1.3% per year (p<0.001). The largest increase is seen in cervical adenocarcinoma with an average annual percent change of 2.9% (p<0.001). When performing an intersection analysis of race, region and age, White women in the South aged 40-44 have the highest rise in distant cervical cancer at a rate of 4.5% annually (p<0.001). Using the Behavioral Risk Factor Surveillance System and TeenVax data, compared with Black women, we found that White women have a nearly two-fold higher rate of missed or lack of guideline screening, 26.6% vs 13.8%. White teenagers (13-17 years) have the lowest human papillomavirus vaccination rate at 66.1% compared with others at 75.3%. CONCLUSIONS: Black women have a higher incidence of distant stage disease compared with White women. However, White women have a greater annual increase, particularly in adenocarcinomas. Compared with Black women, White women also have lower rates of guideline screening and vaccination.

Precision medicine for cervical cancer.

PURPOSE OF REVIEW: To summarize the data on precision medicine for cervical cancer including the use of potential biomarkers. We also review ongoing areas of research in cervical cancer therapeutics. RECENT FINDINGS: In the current clinical practice, programmed death ligand 1 (PD-L1) expression is used to select patients with cervical cancer for treatment with checkpoint inhibitors. However, more recently presented data suggest that PD-L1 may not be a fully accurate biomarker for selection and further analysis is warranted. With the publication of the molecular landscape of cervical cancer, tumor profile-based therapy selection is of greater interest (i.e. targeting PI3K and HER2). SUMMARY: In this review, we discuss the role of potential biomarkers for cervical cancer that may assist with the selection of precision therapies. Enrolling patients on active clinical trials will help clarify the role of targeting specific mutations.

Surgical Science-Simbionix Robotic Hysterectomy Simulator: Validating a New Tool.

STUDY OBJECTIVE: To gather validity evidence for and determine acceptability of Surgical Science-Simbionix Hysterectomy Modules for the DaVinci Xi console simulation system (software; 3D Systems by Simbionix [now Surgical Science-Simbionix], Littleton, CO, and hardware; Intuitive Surgical, Inc., Sunnyvale, CA) and evaluate performance benchmarks between novice and experienced or expert surgeons. DESIGN: Prospective education study (Messick validity framework). SETTING: Multicenter, academic medical institutions. PARTICIPANTS: Residents, fellows, and faculty in obstetrics and gynecology were invited to participate at 3 institutions. Participants were categorized by experience level: fewer than 10 hysterectomies (novice), 10 to 50 hysterectomies (experienced), and more than 50 hysterectomies (expert). A total of 10 novice, 10 experienced, and 14 expert surgeons were included. INTERVENTIONS: Participants completed 4 simulator modules (ureter identification, bladder flap development, colpotomy, complete hysterectomy) and a qualitative survey. Simulator recordings were reviewed in duplicate by educators in minimally invasive gynecologic surgery using the Modified Global Evaluative Assessment of Robotic Skills (GEARS) rating scale. MEASUREMENTS AND MAIN RESULTS: Most participants felt that the simulator realistically simulated robotic hysterectomy (64.7%) and that feedback provided by the simulator was as or more helpful than feedback from previous simulators (88.2%) but less helpful than feedback provided in the operating room (73.5%). Participants felt that this simulator would be helpful for teaching junior residents. Simulator-generated metrics correlated with GEARS performance for the bladder flap and ureter identification modules in multiple domains including total movements and total time for completion. GEARS performance for the bladder flap module correlated with experience level (novice vs experienced/expert) in the domains of interest and total score but did not consistently correlate for the other procedural modules. Performance benchmarks were evaluated for the bladder flap module for each GEARS domain and total score. CONCLUSION: The modules were well received by participants of all experience levels. Individual simulation modules appear to better discriminate between novice and experienced/expert users than overall simulator performance. Based on these data and participant feedback, the use of individual modules in early residency education may be helpful for providing feedback and may ultimately serve as 1 component of determining readiness to perform robotic hysterectomy.

Phase I evaluation of lenvatinib and weekly paclitaxel in patients with recurrent endometrial, ovarian, fallopian tube, or primary peritoneal Cancer.

OBJECTIVES: To estimate the maximally tolerated dose (MTD) and describe toxicities associated with lenvatinib and weekly paclitaxel in patients with recurrent endometrial and platinum resistant epithelial ovarian cancer. METHODS: Using a 3 + 3 design patients were given weekly paclitaxel 80 mg/m2 IV day 1, 8, 15 and oral levantinib daily on a 28-day cycle. Lenvatinib dose levels were 8 mg, 12 mg, 16 mg, 20 mg. Toxicities were recorded using CTCAE v4.03 and response was determined with imaging after cycle 2, then every 3rd cycle, using RECIST 1.1 criteria. RESULTS: 26 patients were enrolled; 19 with ovarian cancer (14 high grade serous, 1 low grade serous, 2 clear cell, 1 endometrioid, and 1 carcinosarcoma), and 7 with endometrial cancer (3 serous, and 4 endometrioid). The MTD was established at lenvatinib 16 mg and weekly paclitaxel 80 mg/m2. Toxicities (all grades) occurring in ≥25% of patients included anemia, neutropenia, lymphopenia, mucositis, nausea, diarrhea, anorexia, hypertension, fatigue, proteinuria, epistaxis, hoarseness. Twenty-three patients were evaluable for response and PFS; 15 (65%) had a partial response, 7 (30%) stable, 1 (4%) progressive disease with an objective response rate of 65%; 71% in ovarian and 50% in endometrial cancer. Median progression free survival (PFS) is 12.4 months; 14.0 months in endometrial cancer, 7.2 months in ovarian cancer; 54% had a PFS > 6 months. The median duration of response for PR patients (n = 15) was 10.9 months. CONCLUSIONS: The regimen was tolerable with manageable side effects. Encouraging activity was observed in endometrial and ovarian cancer, and warrants further development.

Patient-reported outcome changes at the end of life in recurrent platinum-resistant ovarian cancer: An NRG oncology/GOG study.

OBJECTIVES: In a prospective study of platinum-resistant ovarian cancer patients, we examined whether the Disease-related Symptoms-Physical (DRS--P) scale of the NCCN/FACT-Ovarian Cancer Symptom Index-18 (NFOSI-18) is responsive to clinical change in patients estimated by their provider to survive at least six months. METHODS: The NFOSI-18, and other FACT measures, was collected at study entry and 3 and 6 months post-enrollment. Measures were compared for those who died or dropped off study prior to 3 months or prior to 6 months (assumed as health deterioration over time), or those who stayed on study through 6 months (presumed as stable disease over time). Statistical analyses included a fitted linear mixed model for estimating the group differences over time, Cox regression to assess the probability of survival with patient-reported outcomes, and effect size. RESULTS: DRS-P scores of patients who completed only one assessment were significantly lower compared to patients who were able to complete two assessments [5.9 points lower (2.0-9.8); p < 0.01], or three assessments [8.1 points lower (4.8-11.5); p < 0.01]. Measures of abdominal discomfort, functional well-being, emotional well-being, and quality of life were also significant, but treatment side effects were not. Further, in every scale except for neurotoxicity, higher (better) baseline scores were associated with a decreased likelihood of death, after adjusting for age, performance and disease status. CONCLUSION: The NFOSI-18 DRS-P scale is responsive to clinical change. It has potential as an indicator of changing health status with ovarian cancer disease progression, distinct from treatment side effects.
