The current state of molecular testing in the treatment of patients with solid tumors, 2019.

The world of molecular profiling has undergone revolutionary changes over the last few years as knowledge, technology, and even standard clinical practice have evolved. Broad molecular profiling is now nearly essential for all patients with metastatic solid tumors. New agents have been approved based on molecular testing instead of tumor site of origin. Molecular profiling methodologies have likewise changed such that tests that were performed on patients a few years ago are no longer complete and possibly inaccurate today. As with all rapid change, medical providers can quickly fall behind or struggle to find up-to-date sources to ensure he or she provides optimum care. In this review, the authors provide the current state of the art for molecular profiling/precision medicine, practice standards, and a view into the future ahead.

A paradigm shift in understanding vulvovaginal melanoma as a distinct tumor type compared with cutaneous melanoma.

OBJECTIVE: Our goal was to compare molecular and immune profiles of vulvovaginal melanoma (VVM) with cutaneous melanoma (CM) and explore the significance of immune checkpoint inhibitor (ICI) agents on survival. METHODS: Samples from VVM and CM tumors underwent comprehensive molecular and immune profiling. Treatment and survival data were extracted from insurance claims data and OS was calculated from time of ICI treatment to last contact. Statistical significance was determined using chi-square and Wilcoxon rank sum test and adjusted for multiple comparisons. RESULTS: Molecular analysis was performed on 142 VVM and 3823 CM tumors. VVM demonstrated significantly (q < 0·01) less frequent BRAF and more frequent KIT, ATRX, and SF3B1 mutations. Alterations in pathways involving DNA damage and mRNA splicing were more common in VVM, while alterations in cell cycle and chromatin remodeling were less common. Immunogenicity of VVM was lower than CM, with an absence of high TMB (0% vs 46.9%) and lower PD-L1 positivity (18·0% vs 29·5%). Median immune checkpoint gene expression was lower in VVM, as were cell fractions for type I macrophages and CD8+ T-cells(q < 0·01). Myeloid dendritic cells were increased in VVM(q < 0·01). Median OS was shorter for VVM than for CM patients treated with ICIs (17·6 versus 37·9 months, HR:1·65 (95% CI 1·02-2·67) p = 0·04). CONCLUSIONS: VVM has a distinct molecular and immune profile compared to CM, which may contribute to the worse survival in VVM compared to CM patients treated with ICI therapy. Though ICIs have been a mainstay of treatment in recent years, our findings suggest that new therapeutic strategies are needed.

Molecular portraits of clear cell ovarian and endometrial carcinoma with comparison to clear cell renal cell carcinoma.

OBJECTIVE: Advanced clear cell gynecologic malignancies remain among the most challenging diseases to manage. We evaluated ovarian and endometrial clear cell carcinoma (OCCC and ECCC) specimens using comprehensive sequencing technology to identify mutational targets and compared their molecular profiles to histologically similar clear cell renal cell carcinoma (ccRCC). METHODS: Using next-generation sequencing (NGS), fragment analysis (FA), and in situ hybridization (ISH), 164 OCCC, 75 ECCC and 234 ccRCC specimens from 2015 to 2018 were evaluated and compared. RESULTS: The highest mutation rates in ECCC and OCCC were noted in: ARID1A (75.0%, 87.5%), TP53 (34.8%, 11.1%), PIK3CA (25.0%, 46.8%), PPP2R1A (8.7%, 16.7%), MSI-high (8.8%, 6.4%) and PTEN (8.3%, 7.1%). Among these mutations, there was no significant difference between OCCC and ECCC mutation prevalence except in TP53, with higher mutation rates in ECCC versus OCCC (34.8 vs. 11.1%, respectively, p < 0.05). ccRCC demonstrated different mutation profiles with higher mutation rates in VHL (80.3%), PBRM1 (43.9%), SETD2 (31.1%), and KDM5C (29.2%). By contrast, VHL, PBRM1, and SETD2 mutations were not found in ECCC and OCCC (0.0%). Compared to ccRCC and ECCC, OCCC was found to have a significantly higher tumor mutation burden (TMB) (19.1%). CONCLUSION: Gynecologic and renal CCC demonstrate separate and disparate somatic profiles. However, OCCC and ECCC are diseases with similar profiles. TMB and MSI analyses indicate that a subset of OCCC may benefit from immunotherapy. Prospective clinical trials are needed and are underway to examine targeted therapies in these gynecologic disease subtypes.

A plain language summary of results from the GARNET study of dostarlimab in patients with endometrial cancer.

WHAT IS THIS SUMMARY ABOUT?: Dostarlimab, also known by the brand name JEMPERLI, is a medicine that can be used to treat certain types of endometrial cancer. GARNET is an ongoing phase 1 clinical study that is testing the safety and side effects of dostarlimab and the best way to administer it to patients. The results presented in this summary are from a time point in the middle of the study. WHAT WERE THE RESULTS?: The results from the GARNET study published in 2022 showed how well dostarlimab worked for people participating in the study. Dostarlimab was found to reduce the size of tumors in patients with certain types of endometrial cancer. The patients treated with dostarlimab had side effects that could be managed and few severe side effects. WHAT DO THE RESULTS MEAN?: The results of the GARNET study led to dostarlimab being approved to treat patients with certain types of endometrial cancer. For patients with advanced-stage endometrial cancer, or endometrial cancer that has come back after chemotherapy (recurrent), there are few treatment options. The results suggest that dostarlimab may provide long-term benefits for these patients.

Opioid and benzodiazepine use in gynecologic oncology patients.

OBJECTIVE: The goals of this study were to describe opioid and benzodiazepine prescribing practices in the gynecologic oncology patient population and determine risks for opioid misuse in these patients. METHODS: Retrospective study of opioid and benzodiazepine prescriptions for patients treated for cervical, ovarian (including fallopian tube/primary peritoneal), and uterine cancers within a single healthcare system from January 2016 to August 2018. RESULTS: A total of 7643 prescriptions for opioids and/or benzodiazepines were dispensed to 3252 patients over 5754 prescribing encounters for cervical (n=2602, 34.1%), ovarian (n=2468, 32.3%), and uterine (n=2572, 33.7%) cancer. Prescriptions were most often written in an outpatient setting (51.0%) compared with inpatient discharge (25.8%). Cervical cancer patients were more likely to have received a prescription in an emergency department or from a pain/palliative care specialist (p=0.0001). Cervical cancer patients were least likely to have prescriptions associated with surgery (6.1%) compared with ovarian cancer (15.1%) or uterine cancer (22.9%) patients. The morphine milligram equivalents prescribed were higher for patients with cervical cancer (62.6) compared with patients with ovarian and uterine cancer (46.0 and 45.7, respectively) (p=0.0001). Risk factors for opioid misuse were present in 25% of patients studied; cervical cancer patients were more likely to have at least one risk factor present during a prescribing encounter (p=0.0001). Cervical cancer was associated with a higher number of risk factors (p<0.001). CONCLUSIONS: Opioid and benzodiazepine prescribing patterns differ for cervical, ovarian, and uterine cancer patients. Gynecologic oncology patients are overall at low risk for opioid misuse; however, patients with cervical cancer are more likely to have risk factors present for opioid misuse.

Low-grade serous ovarian cancer: expert consensus report on the state of the science.

Compared with high-grade serous carcinoma, low-grade serous carcinoma of the ovary or peritoneum is a less frequent epithelial ovarian cancer type that is poorly sensitive to chemotherapy and affects younger women, many of whom endure years of ineffective treatments and poor quality of life. The pathogenesis of this disease and its management remain incompletely understood. However, recent advances in the molecular characterization of the disease and identification of novel targeted therapies with activity in low-grade serous carcinoma offer the promise of improved outcomes. To update clinicians regarding recent scientific and clinical trial advancements and discuss unanswered questions related to low-grade serous carcinoma diagnosis and treatment, a panel of experts convened for a workshop in October 2022 to develop a consensus document addressing pathology, translational research, epidemiology and risk, clinical management, and ongoing research. In addition, the patient perspective was discussed. The recommendations developed by this expert panel-presented in this consensus document-will guide practitioners in all settings regarding the clinical management of women with low-grade serous carcinoma and discuss future opportunities to improve research and patient care.

Enhanced recovery after surgery (ERAS) protocol is associated with lower post-operative opioid use and a reduced office burden after minimally invasive surgery.

OBJECTIVE: Enhanced recovery after surgery (ERAS) has decreased hospital opioid use, but less attention has been directed towards its impact on clinic burden with respect to post-operative care. Our objective was to determine the impact of an ERAS protocol on post-operative opioid prescribing, and the subsequent number of pain medication refill requests and unscheduled patient-provider interactions in the 30-day post-operative period. METHODS: IRB-approved retrospective study comparing post-operative opioid prescription practices 10 months before and 10 months after ERAS protocol implementation after minimally invasive gynecologic surgery. Opioid doses in morphine milligram equivalents (MMEs), number of unscheduled visits, and phone calls were compared before and after ERAS implementation. RESULTS: A total of 791 patients were included; 445 without and 346 with ERAS implementation. ERAS was associated with higher rates of same day discharge (49% vs 39%, p = 0.003) and lower readmission rates (2.0% vs 5.6%, p = 0.011). Post-operatively, patients who received the ERAS protocol were prescribed less opioids (197.8 vs. 223.5 MMEs, p = 0.0087). There was a trend towards less refill requests with ERAS (1.7% vs 3.6%, p = 0.11). ERAS was associated with a decreased number of post-operative phone calls (38% vs 46%, p = 0.023), including calls for pain (10% vs 16%, p = 0.021), and fewer unscheduled visits related to pain (1.5% vs 5.8%, p = 0.001). CONCLUSIONS: Implementation of the ERAS protocol resulted in a decrease in post-operative opioid prescribing. Despite the lower amount of prescribed post-operative opioids, the ERAS protocol translated into a decrease in the need for post-operative interactions with the clinic staff, specifically encounters associated with pain.

Genomic profiling in low grade serous ovarian cancer: Identification of novel markers for disease diagnosis and therapy.

OBJECTIVES: Low grade serous ovarian cancer (LGSOC) differs from high grade serous in terms of pathogenesis, molecular, genetic, and clinical features. Molecular studies have been hampered by small sample sizes, heterogenous histology, and lack of comprehensive testing. We sought to molecularly profile LGSOC in a homogenously tested, histologically confirmed cohort. METHODS: Using hot-spot and whole exome next generation sequencing (NGS), fusion gene analysis interrogating RNA, fragment analysis, in situ hybridization and/or immunohistochemistry, 179 specimens were evaluated by Caris Life Sciences (Phoenix, AZ). A second independent histologic review confirmed histology in 153 specimens. RESULTS: Most frequently mutated genes (5% or greater) were members of the mitogen-activated protein kinase (MAPK) pathway: KRAS (23.7%, n = 36), NRAS (11.2%, n = 19), NF1 (7.9%, n = 5), and BRAF (6.6%, n = 10). Class III mutations were seen in 3 of 10 BRAF mutations while 7 were Class I V600E. Overall, estrogen and progesterone receptor expression was 80.2% (n = 130) and 27.8% (n = 45), respectively. Of those that were hormone negative, nearly 50% contained KRAS or NF1 mutations. None were NRAS mutated. Markers of response to immunotherapy were low to absent. CONCLUSION: BRAF mutations were seen to be lower than those traditionally reported. With increased MAPK activation resulting in ligand independent activation of ERα, a role of combination therapy with hormonal and targeted therapy should be considered as 49.2% of hormone negative specimens were KRAS or NF1 mutated. Absence of immunotherapy biomarkers suggest limited benefit to immunotherapeutic agents.

Molecular profiles of endometrial cancer tumors among Black patients.

OBJECTIVES: Disparate outcomes exist between Black and White patients with endometrial cancer (EC). One contributing factor is the disproportionately low representation of Black patients in clinical trials and in tumor molecular profiling studies. Our objective was to investigate molecular profiles of ECs in a cohort with a high proportion of tumors from Black patients. METHODS: A total of 248 EC samples and self-reported race data were collected from 6 institutions. Comprehensive tumor profiling and analyses were performed by Caris Life Sciences. RESULTS: Tumors from 105 (42%) Black and 143 (58%) White patients were included. Serous histology (58% vs 36%) and carcinosarcoma (25% vs 16%), was more common among Black patients, and endometrioid was less common (17% vs 48%) (p < 0.01). Differences in gene mutations between cohorts corresponded to observed histologic differences between races. Specifically, TP53 mutations were predominant in serous tumors. In endometrioid tumors, mutations in ARID1A were the most common, and high rates of MSI-H, MMRd, and TMB-H were observed. In carcinosarcoma tumors, hormone receptor expression was high in tumors of Black patients (PR 23.4%, ER 30.8%). When stratified by histology, there were no significant differences between tumors from Black and White women. CONCLUSIONS: This cohort had a high proportion of tumors from Black women. Distinct molecular profiles were driven primarily by more aggressive histologic subtypes among Black women. Continued effort is needed to include Black women and other populations under-represented in EC molecular profiling studies as targeted therapies and personalized medicine become mainstream.

HER2 in Uterine Serous Carcinoma: Testing platforms and implications for targeted therapy.

OBJECTIVE: HER2 is an important prognostic and therapeutic target in uterine serous carcinoma (USC). Optimal HER2 testing platforms have not been defined and guidelines for testing have changed over time. Our objective is to assess the concordance of HER2 positivity based on chromogenic in situ hybridization (CISH), immunohistochemistry (IHC), and next generation sequencing (NGS) and to determine the rate of downstream mutations that may affect response to HER2 directed therapy. METHODS: Utilizing the Caris tumor registry, 2192 USC tumors were identified and analyzed using NGS (NextSeq, 592 Genes and WES, NovaSEQ), IHC, and CISH. PD-L1 expression was tested by IHC. Microsatellite instability was tested by fragment analysis, IHC, and NGS. Tumor mutational burden (TMB) was measured by totaling somatic mutations per tumor. HER2 positivity through IHC and CISH was determined based on 2007 and 2018 ASCO/CAP HER2 breast cancer guidelines. RESULTS: There was a higher rate of HER2 positivity by IHC when using the 2018 guidelines compared to the 2007 guidelines (16.3% vs 12.3%). Concordance between IHC and CISH was 98.9%. ERBB2 amplification was identified by NGS in 10.5% of tumors. Compared to CISH results, this corresponds to a concordance rate of 91.6% and a positive predictive value (PPV) of 60.3%. Single gene alterations in HER2 amplified tumors that may implicate HER2 therapy resistance included PI3K (33.1%), KRAS (2.5%), and PTEN (1.3%). CONCLUSIONS: There was high concordance between HER2 positivity based on CISH and IHC. Rate of HER2 positivity is the lowest by NGS. Ultimately these testing platforms need to be validated by response to targeted therapy.

The MEMORY Study: MulticentEr study of Minimally invasive surgery versus Open Radical hYsterectomy in the management of early-stage cervical cancer: Survival outcomes.

OBJECTIVE: The Laparoscopic Approach to Cervical Cancer (LACC) trial found that minimally invasive radical hysterectomy compared to open radical hysterectomy compromised oncologic outcomes and was associated with worse progression-free survival (PFS) and overall survival (OS) in early-stage cervical carcinoma. We sought to assess oncologic outcomes at multiple centers between minimally invasive (MIS) radical hysterectomy and OPEN radical hysterectomy. METHODS: This is a multi-institutional, retrospective cohort study of patients with 2009 FIGO stage IA1 (with lymphovascular space invasion) to IB1 cervical carcinoma from 1/2007-12/2016. Patients who underwent preoperative therapy were excluded. Squamous cell carcinoma, adenocarcinoma, and adenosquamous carcinomas were included. Appropriate statistical tests were used. RESULTS: We identified 1093 cases for analysis-715 MIS (558 robotic [78%]) and 378. OPEN procedures. The OPEN cohort had more patients with tumors >2 cm, residual disease in the hysterectomy specimen, and more likely to have had adjuvant therapy. Median follow-up for the MIS and OPEN cohorts were 38.5 months (range, 0.03-149.51) and 54.98 months (range, 0.03-145.20), respectively. Three-year PFS rates were 87.9% (95% CI: 84.9-90.4%) and 89% (95% CI: 84.9-92%), respectively (P = 0.6). On multivariate analysis, the adjusted HR for recurrence/death was 0.70 (95% CI: 0.47-1.03; P = 0.07). Three-year OS rates were 95.8% (95% CI: 93.6-97.2%) and 96.6% (95% CI: 93.8-98.2%), respectively (P = 0.8). On multivariate analysis, the adjusted HR for death was 0.81 (95% CI: 0.43-1.52; P = 0.5). CONCLUSION: This multi-institutional analysis showed that an MIS compared to OPEN radical hysterectomy for cervical cancer did not appear to compromise oncologic outcomes, with similar PFS and OS.

Patient-reported outcomes in the GARNET trial in patients with advanced or recurrent mismatch repair-deficient/microsatellite instability-high endometrial cancer treated with dostarlimab.

OBJECTIVE: There is an increase in patient-reported outcome assessments to gain information on new drug candidates from the patient's perspective. A data gap remains in patient-reported outcome measurements for anti-programmed death 1 (anti-PD-1) therapies in endometrial cancer. We present patient-reported outcome measures collected from patients with mismatch repair-deficient/microsatellite instability-high advanced or recurrent endometrial cancer treated with dostarlimab, an anti-PD-1 monoclonal antibody, in an expansion cohort of the GARNET trial. METHODS: GARNET (NCT02715284) is a phase I single-arm study of dostarlimab monotherapy in multiple tumor types. Patients with advanced or recurrent mismatch repair-deficient/microsatellite instability-high endometrial cancer were treated with 500 mg of intravenous dostarlimab once every 3 weeks for four cycles, then 1000 mg of intravenous dostarlimab every 6 weeks. Patient-reported outcome assessments were an exploratory endpoint, measured using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30). RESULTS: At data cut-off, 88 patients with mismatch repair-deficient endometrial cancer were included in the analysis. Patient-reported outcome assessment completion was >95.5% throughout cycle 7 of the trial, with no individual domain completion <90.9%. Quality of life, emotional functioning, and social functioning showed improvement compared with baseline. All symptom scores showed either improvement or stability from baseline through cycle 7. Categorical change in response across all symptom scales and single-item response scores showed stability or improvement for most patients. For patients who saw a worsening of their categorical change in response, ≤7.4% experienced a 2-category worsening and ≤2.5% experienced a 3-category worsening. CONCLUSIONS: Most patients remained stable or had improved quality of life while receiving dostarlimab for the treatment of recurrent or advanced mismatch repair-deficient endometrial cancer. TRIAL REGISTRATION NUMBER: NCT02715284.

Factors Associated with Same Day Discharge after Laparoscopic Surgery in Gynecologic Oncology.

STUDY OBJECTIVE: To identify factors associated with same day discharge (SDD) after laparoscopic surgery in gynecologic oncology. DESIGN: Retrospective cohort. SETTING: Teaching hospital. PATIENTS: Total of 800 patients having minimally invasive surgery in the division of gynecologic oncology during a 20-month period. INTERVENTION: Minimally invasive surgery cases were reviewed for determinants of SDD to identify factors that could improve the SDD rate. MEASUREMENTS AND MAIN RESULTS: During the study period, 800 minimally invasive procedures were performed with a 43.0% SDD rate. Patients who had SDD were younger (52.3 years vs 58.0 years; p <.001), had a lower body mass index (31.1 kg/m2 vs 33.7 kg/m2; p <.001), were less likely to have a malignancy (28.2% vs 55.5%; p <.001), had a lower estimated blood loss (36 vs 72 mL; p <.001), and were more likely to have received an enhanced recovery after surgery protocol (49.8% vs 39.3%; p <.003). Total surgical time was shorter in women with SDD (156 minutes vs 208 minutes) as was total narcotic use in morphine equivalents (MEq) (milligram intravenous MEq, 23.1 mg MEq vs 28.8 mg MEq). SDD was also associated with earlier start time (p <.001). Laparoscopic cases were most likely to have SDD (51.4%) as compared with robotic assisted surgery (16.1%) or minilaparotomy (10.5%). There was a wide range of SDD among surgeons ranging from 19.8% to 56.2% (p <.001). In a multivariate analysis, the factors predicting SDD in order of predictive factors were surgical time (p <.001), recovery time (p <.001), start time (p <.001), surgeon (p <.001), age (p <.001), estimated blood loss (p <.001), and type of surgery (p = .005). CONCLUSION: Multiple factors affect SDD. Modifiable factors for SDD include the start time, surgeon preference, and patient expectations for SDD. Given these data, centers should prioritize surgical order by which patients are more likely to go home, and surgeons should analyze their own data with respect to achieving higher SDD rates.

Improved Rates of Same-day Discharge in Patients Undergoing Surgery for Endometrial Cancer Following the COVID-19 Pandemic.

STUDY OBJECTIVE: To determine the effect of the coronavirus disease 2019 (COVID-19) pandemic on the rate of same-day discharge (SDD) after minimally invasive surgery for endometrial cancer. DESIGN: Retrospective cohort. SETTING: Teaching hospital. PATIENTS: A total of 166 patients underwent a minimally invasive surgery procedure for the indication of endometrial cancer at a large academic institution from September 1, 2019, to October 1, 2020-80 patients before the implementation of the COVID-19 restrictions and 86 patients after. INTERVENTIONS: COVID-19 pandemic with visitor restrictions and hospital policy changes placed on March 17, 2020. MEASUREMENTS AND MAIN RESULTS: SDD rate was increased by 18% after the start of the COVID-19 pandemic (40% vs 58%, p = .02). There were no differences between the 2 groups with regard to operative time (p = .07), estimated blood loss (p = .21), uterine weight (p = .12), age (p = .06), body mass index (p = .42), or surgery start time (p = .15). In a multivariable logistic regression model, subjects in the COVID-19 group had 3.08 times (95% confidence interval, 1.40-6.74; p = .01) higher odds of SDD than those in the pre-COVID-19 group. There was no difference in 30-day readmission rates (7.5% vs 5.8%, p = .66). CONCLUSION: There was a significant increase in the SDD of patients with endometrial cancer since the start of the COVID-19 pandemic. The pandemic has strained hospital resources and motivated patients and physicians to avoid hospitalization. This shows that with proper motivation, an increase in SDD rates is possible without an increase in complications or rehospitalization.

Uterine carcinosarcomas: From pathology to practice.

OBJECTIVE: Uterine carcinosarcoma (UCS) is a rare but aggressive cancer. In early-stage disease data guiding treatment is sparse. The purpose of this review is to summarize the findings from the 2019 NRG oncology group summer symposium meeting as well as a review of the current literature, with a particular focus on molecular targets, ongoing clinical trials, and treatment of early and advanced/recurrent disease. METHODS: A combination of expert presentations and an extensive literature search was undertaken to summarize the literature in this review. MEDLINE was queried for peer-reviewed publications on UCS. This search was not limited by year or study design, but was limited to English language publications. ClinicalTrials.gov was queried for ongoing trials in UCS. RESULTS: UCS is a rare cancer that is biphasic, with the carcinomatous component driving its aggressive nature. Level 3 evidence regarding early stage disease is lacking, but retrospective data suggests adjuvant therapy is warranted. The recent results of GOG 261 have contributed valuable information towards treatment strategy, including use of paclitaxel and carboplatin for UCS. Clinical trials are ongoing to investigate new targeted agents in UCS. CONCLUSION: Ongoing endometrial cancer clinical trials now include UCS patients. In combination with advances in molecular profiling, this will provide patients with UCS improved therapeutic options. Until that time, surgical resection and traditional cytotoxic chemotherapy remains standard of care.

The impact of opportunistic salpingectomy on ovarian cancer mortality and healthcare costs: a call for universal insurance coverage.

BACKGROUND: Opportunistic salpingectomy at the time of hysterectomy or as an alternative to bilateral tubal ligation may reduce the incidence of ovarian cancer, because it has been demonstrated that most serous ovarian cancers begin in the fallopian tubes. However, salpingectomy at the time of sterilization is not always financially covered by third-party payers, and this represents a barrier to adoption. Routine salpingectomy has become more common but is not always practiced at the time of hysterectomy. OBJECTIVE: This study aimed to determine the impact of opportunistic salpingectomy as an alternative tubal ligation and routine salpingectomy at the time of hysterectomy on ovarian cancer mortality and overall cost. STUDY DESIGN: An 8-state Markov state transition model was constructed, including hysterectomy, tubal ligation, and ovarian cancer. Transition probabilities were informed by previously reported population data and include age-adjusted rates of elective sterilization and hysterectomy. This model was used to predict ovarian cancer incidence and the cost effectiveness of opportunistic salpingectomy. Testing of this model suggested that it accurately predicted overall life expectancy and closely predicted the rate of hysterectomy in the population. The model may underestimate the rate of tubal sterilization, making it conservative with respect to the benefits of salpingectomy. RESULTS: The recursive Markov model was run from ages 20 to 85 years in 1-year intervals with a half step correction and included age-adjusted rates of tubal ligation, hysterectomy (with and without oophorectomy), and ovarian cancer. The model predicts that opportunistic salpingectomy at the time of tubal ligation will reduce ovarian cancer mortality by 8.13%. Opportunistic salpingectomy at the time of hysterectomy will reduce ovarian cancer mortality by 6.34% for a combined decrease of 14.5%. Both strategies are cost effective when considering only the cost of the opportunistic salpingectomy. The excess cost of opportunistic salpingectomy at the time of tubal ligation was $433.91 with an incremental cost-effective ratio of $6401 per life-year and $5469 per quality-adjusted life year gained when adjusting for ovarian cancer with a utility of 0.64. The incremental cost-effective ratio for opportunistic salpingectomy during hysterectomy at a cost of $124.70 was $2006 per life-year and $1667 per quality-adjusted life year. When considering the impact of ovarian cancer prevention with respect to the cost of ovarian cancer treatment, opportunistic salpingectomy may produce a substantial healthcare savings. Utilizing a 3% discount rate, it is estimated that the total savings for universal salpingectomy could be as high as $445 million annually in the United States. A sensitivity analysis around the benefit of opportunistic salpingectomy suggests that this procedure will be cost effective even if salpingectomy provides only a modest reduction in the risk of ovarian cancer. CONCLUSION: It is estimated that universal opportunistic salpingectomy may prevent 1854 deaths per year from ovarian cancer and may reduce healthcare costs. Given these data, universal opportunistic salpingectomy should be considered at the time of tubal ligation and hysterectomy and covered by third-party payers.

Clinical activity and safety of the anti-PD-1 monoclonal antibody dostarlimab for patients with recurrent or advanced dMMR endometrial cancer.

This document provides a short summary of the GARNET trial which was published in JAMA Oncology in October 2020. At the end of this document, there are links to websites where you can find more information about this study. The trial enrolled adult participants with advanced solid tumors. This report is restricted to patients with a particular type of endometrial cancer that has a deficient mismatch repair (dMMR) status. Patients received a trial treatment called dostarlimab (also known by the brand name Jemperli). In the US, dostarlimab is approved as a single therapy in adult patients with dMMR recurrent or advanced endometrial cancer that has progressed on or after platinum-based chemotherapy. In the EU, dostarlimab is approved as a single therapy in adult patients with recurrent or advanced dMMR/microsatellite instability-high (MSI-H) endometrial cancer that has progressed on or after treatment with a platinum-containing regimen. The GARNET trial looked at dostarlimab given intravenously to patients with dMMR endometrial cancer from 7 countries. The trial showed that dostarlimab was successful in shrinking the tumor in 42% of these patients. In general, the percentage of participants who experienced medical problems (referred to as side effects) was low and within expectations for this type of treatment.

Perioperative Recovery and Narcotic Use in Laparoscopic versus Robotic Surgery for Endometrial Cancer.

STUDY OBJECTIVE: To compare intraoperative and perioperative narcotic use, recovery room time, and total hospital stay for patients treated with robotic vs laparoscopic surgery for endometrial cancer. DESIGN: Retrospective cohort. SETTING: Teaching hospital. PATIENTS: All patients having minimally invasive surgery in the division of gynecologic oncology during a 20-month period. INTERVENTION: Laparoscopic cases were compared with robot-assisted cases with respect to perioperative outcome. MEASUREMENT AND MAIN RESULTS: Hospital billing records were used to identify all patients with endometrial cancer treated from January 1, 2018 through July 31, 2019 undergoing either laparoscopic or robotic surgery. Data were collected including total narcotic use converted to intravenous morphine milligram equivalent (MME), total amount of time in recovery, and length of hospital stay. A total of 139 laparoscopic and 101 robotic surgeries were eligible for analysis. There was no difference between the groups with respect to blood loss, alcohol use, or smoking. Patients undergoing laparoscopy had a significantly lower body mass index compared with patients undergoing robotic surgery (32.9 vs 38.0 kg/m2; p <.001). Univariate analysis showed no difference between the 2 groups with respect to narcotic use in surgery (21.7 vs 21.1 MME; p = .64), recovery (4.3 vs 4.5 MME; p = .70), or total dose (26.0 vs 25.6 MME; p = .78). However, patients who underwent a robotic approach had a longer recovery room time (128 minutes vs 163 minutes; p <.001 and a longer surgical time (288 minutes vs 204 minutes; p = .001). Patients in the robotic group were also more likely to undergo full lymphadenectomy than patients in the laparoscopy group (38.0% vs 20.8% p <.001). In a multivariate analysis, the only significant factors for predicting total narcotic dose were age, use of a preoperative enhanced recovery after surgery program, and surgical time. Patients who had laparoscopy were more likely to achieve same-day discharge (39.3% vs 17.8%; p <.001), but in the multivariate analysis, the type of surgery did not predict same-day discharge. CONCLUSION: There was no difference in narcotic use in the perioperative period with robotic surgery compared with laparoscopy. Recovery time was longer for robotic surgery, but this was not significant in multivariate analysis. Same-day discharges were less frequent with robotics, which may be more related to the physician's choice rather than the procedure.

Outcomes of Minimally Invasive versus Open Radical Hysterectomy for Early Stage Cervical Cancer Incorporating 2018 FIGO Staging.

STUDY OBJECTIVE: To compare outcomes after minimally invasive surgery (MIS) vs open radical hysterectomy for early stage cervical cancer incorporating 2018 Federation of Gynecology and Obstetrics (FIGO) staging. DESIGN: A retrospective analysis. SETTING: A single teaching hospital. PATIENTS: Patients after radical hysterectomy for stage IA1 with lymphovascular invasion, IA2, or IB1 squamous, adenosquamous, or adenocarcinoma of the cervix between 2007 and 2018, mirroring the Laparoscopic Approach to Cervical Cancer trial criteria. INTERVENTIONS: The use of MIS surgery for performing radical hysterectomy. MEASUREMENTS AND MAIN RESULTS: The outcomes were compared between patients undergoing MIS vs open approaches. A total of 126 patients met the inclusion criteria. The approach was open in 44 patients (35%) and MIS in 82 patients (65%); 49% were laparoscopic and 51% were robotic. Distribution based on the 2009 FIGO staging showed 1 stage IA1 with lymphovascular invasion, 15 stage IA2, and 110 stage IB1 patients. Although not statistically significant, the 3-year disease-free survival (DFS) was higher in the open compared to the MIS group (95% vs 87%; p = .17), and the overall survival was higher in the open compared to the MIS group (97% vs 92%; p = .25). Fourteen patients whose disease recurred were Stage IB1 by FIGO 2009 staging; 11/14 were reclassified to a higher stage by 2018 FIGO staging (5/5 open, 6/9 MIS). Adjuvant therapy was recommended for all these patients based on the Sedlis criteria (10/14) or other risk factors (4/14). Despite this, only 1/9 of MIS patients whose disease recurred received adjuvant therapy compared with 3/5 patients whose disease recurred in the open group (p = .05). CONCLUSION: In a cohort of patients similar to that of the Laparoscopic Approach to Cervical Cancer trial, 2018 FIGO staging may be useful to refine indications for MIS radical hysterectomy in early stage cervical cancer. However, disparate outcomes between MIS and open approaches may be explained by differences in compliance with National Comprehensive Cancer Network guidelines for adjuvant therapy.

Comparison of Perioperative Outcomes between Minimally Invasive Sentinel Node Biopsy and Full Lymphadenectomy for Endometrial Cancer.

STUDY OBJECTIVE: To review the perioperative differences between patients undergoing a minimally invasive sentinel lymph node dissection and those undergoing a full lymphadenectomy. DESIGN: Retrospective review. SETTING: Teaching hospital. PATIENTS: All patients undergoing a minimally invasive procedure for endometrial cancer that included nodal evaluation. INTERVENTIONS: Patients who underwent a sentinel lymph node biopsy were compared with those who underwent a full lymphadenectomy at the time of minimally invasive surgery by either laparoscopic or robot-assisted surgery. MEASUREMENTS AND MAIN RESULTS: A total of 241 minimally invasive surgery procedures for endometrial cancer were performed during the 20-month study period. Nodal dissection was indicated and performed in 156 (65%) of these patients, with 93 undergoing a sentinel lymph node biopsy and 63 a full lymphadenectomy. There was no difference between the sentinel group and the lymphadenectomy group with respect to age, estimated blood loss (p = .23), use of a preoperative enhanced recovery after surgery program (p = .82), or body mass index (34.0 kg/m2 vs 33.7 kg/m2; p = .87). The use of full lymphadenectomy was very dependent on the surgeon (p <.001). There was no difference in narcotic use in milligram intravenous equivalents of morphine in surgery (20.9 vs 22.2; p = .37), recovery (4.6 vs 4.9; p = .73), or total dose (25.4 vs 27.0; p = .33). The surgical procedure was longer with lymphadenectomy (185.2 minutes vs 214.2 minutes; p <.001) and the relative risk of discharge from recovery was lower (0.71; 95% confidence interval, 0.51-0.97; p = .03). The hospital stay was longer with lymphadenectomy (16.3 hours vs 25.5 hours; p <.001) and same-day discharge less frequent (48.5% vs 13.8%; p <.001). A multivariate analysis confirmed that sentinel node biopsy was associated with an increased relative risk of discharge of 1.68 (95% confidence interval 1.11-2.53; p = .01) CONCLUSION: Total narcotic requirements are similar between sentinel node biopsy and lymphadenectomy. However, sentinel node biopsy is associated with a shorter surgical time, recovery time, and hospital stay.
