RESUMO
OBJECTIVE: To identify characteristics associated with long-term progression-free survival (≥2 years) in patients with advanced ovarian cancer treated with niraparib first-line maintenance therapy in the phase III PRIMA/ENGOT-OV26/GOG-3012 study. METHODS: In this post hoc analysis of PRIMA, patients randomized to niraparib were grouped based on investigator-assessed progression-free survival (progressive disease/censoring <2 years or ≥2 years after randomization). Variables assessed for predictive value were Eastern Cooperative Oncology Group performance status, International Federation of Gynecology and Obstetrics (FIGO) stage at diagnosis, clinical response to platinum-based chemotherapy, number of prior chemotherapy cycles, primary tumor location, body mass index, categorical age, debulking surgery type, number of baseline target lesions, number of baseline non-target lesions, BRCA/homologous recombination-deficiency status, residual disease status, and duration from end of chemotherapy to randomization. Logistic regression modeling using backward elimination (significance level=0.15) identified covariates associated with long-term progression-free survival (clinical cut-off date November 17, 2021). RESULTS: Of 487 patients randomized to niraparib, 152 (31%) had progressive disease/censoring ≥2 years after randomization. Multivariable logistic regression modeling using backward elimination identified BRCA1/2 mutation/homologous recombination deficiency status (p<0.0001), FIGO stage (p=0.041), primary tumor location (p=0.095), and number of baseline non-target lesions (p=0.0001) to be associated with long-term progression-free survival. Patients significantly more likely to achieve progression-free survival of ≥2 years in the final model were those with BRCA1- and BRCA2-mutated/homologous recombination-deficient tumors or BRCA wild-type/not determined/homologous recombination-deficient tumors (vs BRCA wild-type/homologous recombination-proficient/not determined tumors), FIGO stage III (vs IV), and 0 or 1 baseline non-target lesions (vs ≥2 baseline non-target lesions). CONCLUSIONS: The hypothesis-generating results of this analysis suggest that BRCA1/2 mutation/homologous recombination-deficiency status, FIGO stage, and number of baseline non-target lesions may predict progression-free survival of ≥2 years in patients with advanced ovarian cancer receiving niraparib first-line maintenance therapy.

What is this summary about? Dostarlimab, also known by the brand name JEMPERLI, is a medicine that uses a patient's own immune system to treat endometrial cancer. Dostarlimab is a type of medicine called an immunotherapy. Immunotherapies help the immune system find and attack cancer cells. Dostarlimab stops cancer cells from being able to hide from the immune system, which allows the patient to have a boosted immune response against their cancer.The RUBY study is a phase 3 clinical study of primary advanced (cancer that has spread outside the uterus) or recurrent (cancer that has come back) endometrial cancer. A phase 3 clinical study looks at how well a new treatment works compared to the standard, or usual, treatment in a large patient population. The RUBY study is testing how well dostarlimab given with chemotherapy, followed by dostarlimab alone, works at delaying primary advanced or recurrent endometrial cancer from getting worse and preventing patients from dying, compared to chemotherapy given alone (the current standard treatment for primary advanced or recurrent endometrial cancer).What were the results? When dostarlimab was given with chemotherapy, this combination was found to delay primary advanced or recurrent endometrial cancer from getting worse and to prevent patients from dying, compared with chemotherapy given alone (without dostarlimab). Patients in the study who received dostarlimab with chemotherapy had a 36% lower risk of dying or having their cancer get worse.What do the results mean? The results from this study contributed to the approval of dostarlimab with chemotherapy as a new treatment option for patients with mismatch repair deficient/microsatellite instability-high primary advanced or recurrent endometrial cancer. As of the publication of this plain language summary of publication (PLSP), this combination of dostarlimab with chemotherapy has been approved in the United States of America, the United Kingdom, the European Union and Hong Kong.Clinical Trial Registration: NCT03981796 (RUBY).

PURPOSE: We examined associations between patient and treatment characteristics with longitudinally collected patient-reported outcome (PRO) measures to provide a data-informed description of the experiences of women undergoing treatment for endometrial cancer. METHODS: We administered National Institutes of Health Patient Reported Outcomes Measurement Information System (PROMIS) questionnaires at the preoperative visit and at 6 and 12 months after surgery. Anxiety, depression, fatigue, sleep disturbance, pain, physical function, and ability to participate in social roles were assessed. Analysis of variance (ANOVA) and linear mixed models were used to examine associations between patient characteristics and PRO measures at baseline and through time. RESULTS: Of 187 women enrolled, 174 (93%) and 103 (69%) completed the 6- and 12-month questionnaires, respectively. Anxiety was substantially elevated at baseline (half of one population-level standard deviation) and returned to general population mean levels at 6 and 12 months. Younger age, Medicaid/None/Self-pay insurance, prevalent diabetes, and current smoking were associated with higher symptom burden on multiple PRO measures across the three time points. Women with aggressive histology, higher disease stage, or those with adjuvant treatment had worse fatigue at 6 months, which normalized by 12 months. CONCLUSIONS: We observed a high symptom burden at endometrial cancer diagnosis, with most PRO measures returning to general population means by 1 year. Information on risk factor-PRO associations can be used during the clinical visit to inform supportive service referral. IMPLICATIONS FOR CANCER SURVIVORS: These findings can inform clinicians' discussions with endometrial cancer survivors regarding expected symptom trajectory following diagnosis and treatment.
RESUMO
OBJECTIVES: The use of a platinum doublet for the treatment of platinum-sensitive epithelial ovarian cancer (EOC) recurrence is well established. The impact of the nonplatinum chemotherapy used as part of a platinum doublet on PARP inhibitor (PARPi) and platinum sensitivity it not known. We aimed to describe oncologic outcomes in cases of recurrent EOC receiving PARPi as maintenance therapy based on preceding platinum doublet. METHODS: Retrospective study of patients with platinum-sensitive recurrent ovarian, fallopian tube or primary peritoneal cancer treated with platinum doublet followed by maintenance PARPi from 1/1/2015 and 1/1/2022. Comparisons were made between patients receiving carboplatin + pegylated liposomal doxorubicin (CD) versus other platinum doublets (OPDs). Descriptive statistics, Kaplan-Meier and univariate survival analyses were performed. RESULTS: 100 patients received PARPi maintenance following a platinum doublet chemotherapy regimen for platinum-sensitive recurrence. 25/100 (25%) received CD and 75/100 (75%) received OPDs. Comparing CD and OPDs, median progression-free survival was 8 versus 7 months (p = 0.26), median time to platinum resistance was 15 versus 13 months (p = 0.54), median OS was 64 versus 90 months (p = 0.28), and median OS from starting PARPi was 25 versus 26 months (p = 0.90), respectively. CONCLUSIONS: Using pegylated liposomal doxorubicin as part of a platinum doublet preceding maintenance PARPi for platinum-sensitive recurrence does not seem to hasten PARPi resistance or platinum resistance compared to OPDs. Although there was a non-significant trend towards increased OS among patients who received a platinum doublet other than CD prior to PARPi, the OS from PARPi start was similar between groups. Given the retrospective nature of this study and small study population, further research is needed to evaluate if the choice of platinum doublet preceding PARPi maintenance impacts PARPi resistance, platinum resistance and survival.

OBJECTIVES: To determine clinical significance of preoperative and pre-chemotherapy CA-125 in high-risk early-stage epithelial ovarian cancer patients. METHODS: All patients with stage IA/IB and grade 3, stage IC, clear cell, or completed resected stage II cancer were enrolled in a phase III trial and treated with chemotherapy. Kaplan-Meier method and Cox proportional hazards model were used for statistical analyses. RESULTS: 427 patients with high-risk early-stage ovarian cancer were enrolled. Of 213 patients with preoperative CA-125 data, 79% had elevated CA-125. Median preoperative CA-125 level was 103 U/mL. Patients with ≤10, 11-15, and > 15 cm tumors had median preoperative CA-125 levels of 62, 131 and 158 U/mL, respectively (p = 0.002). For the 350 patients with data for pre-chemotherapy CA-125 level, 69% had elevated pre-chemotherapy CA-125 above 35 U/mL with median value of 65 U/mL. However, age, race, stage, cell type and grade of disease were not correlated with CA-125 levels before and after surgery. On multivariate analysis, elevated pre-chemotherapy CA-125 independently predicted worse recurrence-free survival (HR = 2.13, 95% CI: 1.23-3.69; p = 0.007) and overall survival (HR = 1.99, 95% CI: 1.10-3.59; p = 0.022) after adjusting for age, stage, cell type and grade of disease. Compared to those with normal CA-125, patients with elevated pre-chemotherapy CA-125 had lower recurrence-free survival (RFS, 87% vs. 75%; p = 0.007) and overall survival (OS, 88% vs. 82%; p = 0.02). However, preoperative CA-125 was not prognostic of RFS (p = 0.699) or OS (p = 0.701). CONCLUSIONS: Preoperative CA-125 was elevated in nearly 80% of high-risk early-stage ovarian cancer patients. Pre-chemotherapy CA-125 was associated with recurrence-free and overall survival; however, preoperative CA-125 was not prognostic.

OBJECTIVE: We sought to assess the impact of antibiotic (ABX) and proton-pump inhibitor (PPI) use on progression-free (PFS) and overall survival (OS) in patients treated with adjuvant platinum-based chemotherapy (PC) for endometrial cancer (EC). METHODS: A retrospective, single-institution cohort study of EC patients treated with ≥four cycles of adjuvant PC following surgical staging from 2014 to 2020. Demographics and clinicopathologic features, including ABX and PPI use, were compared using χ2 and Fisher's exact tests. Univariate and multivariable analyses were performed, and survival outcomes were compared using the log-rank test. RESULTS: Of 325 patients, 95 (29%) received ABX, and 80 (24.6%) received PPI. ABX were associated with decreased 3-year PFS (49.9% vs. 66%; p = 0.0237) but not 3-year OS (68.9% vs. 79.9%; p = 0.0649). ABX targeting gram-positive bacteria were associated with decreased 3-year PFS (21.2% vs. 66.0% vs. 55.4%; p = 0.0038) and 3-year OS (36.5% vs. 79.9% vs. 75.6%; p = 0.0014) compared to no ABX and other ABX, respectively. PPI use was associated with decreased 3-year PFS (46.9% vs. 66.0%; p = 0.0001) and 3-year OS (60.7% vs. 81.9%; p = 0.0041) compared to no PPI. On multivariable regression analysis controlling for confounders including stage, histology, grade, radiation, and co-morbidities, PPI use was independently associated with worse PFS (HR 1.96, 95% CI 1.25-3.08; p = 0.0041) and OS (HR 2.06, 95% CI 1.01-4.18, p = 0.04). CONCLUSION: In this retrospective cohort study, we demonstrate that PPI use is independently associated with worse PFS and OS in patients with EC treated with PC. ABX use was associated with worse PFS on univariate analysis only. There is an unmet need to understand how PPI, ABX, and, potentially, the microbiome impact the effectiveness of chemotherapy in EC patients.

OBJECTIVE: To determine the impact on overall survival (OS) and patient-reported outcomes (PROs) of combining atezolizumab with standard therapy for newly diagnosed stage III/IV ovarian cancer. METHODS: The placebo-controlled double-blind randomized phase III IMagyn050/GOG 3015/ENGOT-OV39 trial (NCT03038100) assigned eligible patients to 3-weekly atezolizumab 1200 mg or placebo for 22 cycles with platinum-based chemotherapy and bevacizumab. Coprimary endpoints were progression-free survival (already reported) and OS in the PD-L1-positive and intent-to-treat (ITT) populations, tested hierarchically. Prespecified PRO analyses focused on disease-related abdominal pain and bloating symptoms (European Organisation for Research and Treatment of Cancer QLQ-OV28), functioning, and health-related quality of life (HRQoL) (QLQ-C30). RESULTS: After 38 months' median follow-up, the OS hazard ratio in the PD-L1-positive population was 0.83 (95% CI, 0.66-1.06; p = 0.13); median OS was not estimable with atezolizumab versus 49.2 months with placebo. The hazard ratio for OS in the ITT population was 0.92 (95% CI, 0.78-1.09; median 50.5 versus 46.6 months, respectively). At week 9, similar proportions of patients in both arms of the neoadjuvant cohort showed ≥10-point improvement from baseline in abdominal pain and bloating, functioning, and HRQoL. In the primary surgery cohort, similar proportions of patients in each arm had improved, stable, or worsened physical and role function and HRQoL from baseline over time. Neither cohort showed differences between arms in treatment-related symptoms or overall side-effect bother. CONCLUSIONS: Incorporation of atezolizumab into standard therapy for newly diagnosed ovarian cancer does not significantly improve efficacy or impose additional treatment burden for patients. CLINICALTRIALS: gov registration: NCT03038100.

OBJECTIVE: To determine the prevalence of Type 2 diabetes mellitus (T2DM) diagnoses during the peri-operative and survivorship periods in patients following surgical management of endometrial cancer (EC). METHODS: An IRB-approved, retrospective single-institution cohort study was performed in patients who underwent surgical management of EC from 2014 to 2020. The perioperative period was defined as the 30 days before and after surgery. T2DM diagnoses occurring during survivorship were recorded. T2DM diagnoses were defined by a HgbA1c ≥6.5% or a random blood glucose ≥200 mg/dL. Sequelae of peri-operative T2DM and predictors of future T2DM were examined utilizing univariate analysis. RESULTS: Of 519 patients meeting inclusion criteria, 37 (7.1%) were diagnosed with T2DM in the perioperative period. Patients diagnosed with T2DM in the perioperative period had significantly higher BMI (p = 0.006) compared to no T2DM, but there were no significant differences in age (p = 0.20), ethnicity/race (p > 0.05) or ECOG score (p = 0.19). The rates of intraoperative complications between groups did not significantly differ, except for vascular complications (p = 0.005), and the incidence of any postoperative complication was higher in the perioperative T2DM group (p = 0.01). With a median follow-up of 29 months [range 11.6-49.0 months], an additional 18.3% (n = 88) of the cohort met diagnostic criteria for T2DM. BMI (p < 0.001), perioperative glucose (p < 0.001), and HgbA1c (p = 0.002) demonstrate risk for a T2DM diagnosis during survivorship. CONCLUSION(S): In this retrospective cohort of EC patients, 25.4% were diagnosed with T2DM, with the majority diagnosed in the survivorship period. Surgical management and subsequent surveillance of EC presents an opportunity to diagnose at-risk patients with T2DM.
RESUMO
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.

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

BACKGROUND: Dostarlimab is an immune-checkpoint inhibitor that targets the programmed cell death 1 receptor. The combination of chemotherapy and immunotherapy may have synergistic effects in the treatment of endometrial cancer. METHODS: We conducted a phase 3, global, double-blind, randomized, placebo-controlled trial. Eligible patients with primary advanced stage III or IV or first recurrent endometrial cancer were randomly assigned in a 1:1 ratio to receive either dostarlimab (500 mg) or placebo, plus carboplatin (area under the concentration-time curve, 5 mg per milliliter per minute) and paclitaxel (175 mg per square meter of body-surface area), every 3 weeks (six cycles), followed by dostarlimab (1000 mg) or placebo every 6 weeks for up to 3 years. The primary end points were progression-free survival as assessed by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1, and overall survival. Safety was also assessed. RESULTS: Of the 494 patients who underwent randomization, 118 (23.9%) had mismatch repair-deficient (dMMR), microsatellite instability-high (MSI-H) tumors. In the dMMR-MSI-H population, estimated progression-free survival at 24 months was 61.4% (95% confidence interval [CI], 46.3 to 73.4) in the dostarlimab group and 15.7% (95% CI, 7.2 to 27.0) in the placebo group (hazard ratio for progression or death, 0.28; 95% CI, 0.16 to 0.50; P<0.001). In the overall population, progression-free survival at 24 months was 36.1% (95% CI, 29.3 to 42.9) in the dostarlimab group and 18.1% (95% CI, 13.0 to 23.9) in the placebo group (hazard ratio, 0.64; 95% CI, 0.51 to 0.80; P<0.001). Overall survival at 24 months was 71.3% (95% CI, 64.5 to 77.1) with dostarlimab and 56.0% (95% CI, 48.9 to 62.5) with placebo (hazard ratio for death, 0.64; 95% CI, 0.46 to 0.87). The most common adverse events that occurred or worsened during treatment were nausea (53.9% of the patients in the dostarlimab group and 45.9% of those in the placebo group), alopecia (53.5% and 50.0%), and fatigue (51.9% and 54.5%). Severe and serious adverse events were more frequent in the dostarlimab group than in the placebo group. CONCLUSIONS: Dostarlimab plus carboplatin-paclitaxel significantly increased progression-free survival among patients with primary advanced or recurrent endometrial cancer, with a substantial benefit in the dMMR-MSI-H population.

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.
RESUMO
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.

OBJECTIVES: Anetumab ravtansine is an antibody-drug conjugate consisting of a fully human anti-mesothelin monoclonal antibody conjugated to cytotoxic maytansinoid tubulin inhibitor DM4. Mesothelin is highly expressed in ovarian cancer. This phase Ib study determines the safety, pharmacokinetics, and anti-tumor activity of anetumab ravtansine and pegylated liposomal doxorubicin in mesothelin-expressing platinum-resistant ovarian cancer. METHODS: Anetumab ravtansine (5.5 or 6.5 mg/kg) and pegylated liposomal doxorubicin (30 mg/m2) were administered intravenously every 3 weeks to 65 patients with platinum-resistant epithelial ovarian cancer. Mesothelin expression was assessed by central immunohistochemistry. Adverse events, tumor response (RECIST 1.1), and progression-free survival were determined. Biomarker samples were assessed by ELISA and next-generation sequencing. RESULTS: In dose escalation, nine patients received anetumab ravtansine across two doses (5.5 or 6.5 mg/kg). The maximum tolerated dose of anetumab ravtansine was 6.5 mg/kg every 3 weeks and no dose-limiting toxicities were observed. In dose expansion, 56 patients were treated at the maximum tolerated dose. The most common treatment-emergent adverse events of any grade were nausea (47.7%), decreased appetite (43.1%), fatigue (38.5%), diarrhea (32.3%), and corneal disorder (29.2%). In all treated patients the objective response rate was 27.7% (95% CI 17.3% to 40.2%), including one complete (1.5%) and 17 partial responses (26.2%), with median duration of response of 7.6 (95% CI 3.3 to 10.2) months and median progression-free survival of 5.0 (95% CI 3.2 to 6.0) months. In an exploratory analysis of a sub-set of patients (n=19) with high mesothelin expression who received ≤3 prior lines of systemic therapy, the objective response rate was 42.1% (95% CI 20.3% to 66.5%) with a median duration of response of 8.3 (95% CI 4.1 to 12.0) months and median progression-free survival of 8.5 (95% CI 4.0 to 11.4) months. CONCLUSIONS: Anetumab ravtansine and pegylated liposomal doxorubicin showed tolerability and promising clinical activity. These results established the dose schedule and the mesothelin-positive target population of this combination for a phase III study in platinum-resistant ovarian cancer. TRIAL REGISTRATION NUMBER: NCT02751918.

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.

PURPOSE: In patients with high-grade ovarian cancer, predictors of bevacizumab efficacy in first-line setting are needed. In the ICON-7 trial, a poor tumor intrinsic chemosensitivity (defined by unfavorable modeled cancer antigen-125 [CA-125] ELIMination rate constant K [KELIM] score) was a predictive biomarker. Only the patients with high-risk disease (suboptimally resected stage III, or stage IV) exhibiting unfavorable KELIM score < 1.0 had overall survival (OS) benefit from bevacizumab (median: 29.7 v 20.6 months; hazard ratio [HR], 0.78). An external validation study in the GOG-0218 trial was performed. METHODS: In GOG-0218, 1,873 patients were treated with carboplatin-paclitaxel ± concurrent-maintenance bevacizumab/placebo. Patient KELIM values were calculated with CA-125 kinetics during the first 100 chemotherapy days by the Lyon University team. The association between KELIM score (favorable ≥ 1.0, or unfavorable < 1.0) and bevacizumab benefit for progression-free survival (PFS)/OS was independently assessed by NGR-GOG using univariate/multivariate analyses. RESULTS: KELIM was assessable in 1,662 patients with ≥ 3 CA-125 available values. An unfavorable KELIM score was associated with bevacizumab benefit compared with placebo (PFS: HR, 0.70; 95% CI, 0.59 to 0.82; OS: HR, 0.87; 95% CI, 0.73 to 1.03), whereas a favorable KELIM was not (PFS: HR, 0.96; 95% CI, 0.79 to 1.17; OS: HR, 1.11; 95% CI, 0.89 to 1.39). The highest benefit was observed in patients with a high-risk disease exhibiting unfavorable KELIM, for PFS (median: 9.1 v 5.6 months; HR, 0.64; 95% CI, 0.53 to 0.78), and for OS (median: 35.1 v 29.1 months; HR, 0.79; 95% CI, 0.65 to 0.97). CONCLUSION: This GOG-0218 trial investigation validates ICON-7 findings about the association between poor tumor chemosensitivity and benefit from concurrent-maintenance bevacizumab, suggesting that bevacizumab may mainly be effective in patients with poorly chemosensitive disease. Bevacizumab may be prioritized in patients with a high-risk and poorly chemosensitive disease to improve their PFS/OS (patient KELIM score calculator available on the Biomarker Kinetics website).

OBJECTIVES: To determine the clinical and prognostic significance of CA-125 trends prior to, during, and after chemotherapy in high-risk early-stage epithelial ovarian cancer patients. METHODS: All patients were enrolled in a phase III randomized trial (GOG 157) following upfront surgery for grade 3 stage IA/IB, stage IC, or stage II disease, and had been treated with either three or six cycles of carboplatin/paclitaxel. Kaplan-Meier method and Cox proportional hazards model were used to evaluate recurrence-free survival (RFS) and overall survival (OS). RESULTS: Of 350 patients, the median pre-chemotherapy CA-125 was 65 (IQR: 31-129). 71% of Whites had an elevated CA-125 compared to 47% of non-Whites (p = 0.006). Following the first cycle of chemotherapy, 74% of those with elevated CA-125 had normalization. Those who had normalization of CA-125 after 1 cycle had significantly better 5-year RFS (81% vs. 65%, p = 0.003) and OS (87% vs. 75%, p = 0.009) compared to those who did not normalize (defined as ≤35 U/mL). The pattern of CA-125 change following chemotherapy cycle 1, from normal to normal vs. elevated to normal vs. elevated to elevated had corresponding RFS of 87% vs. 80% vs. 68% (p = 0.013), and OS of 92% vs. 88% vs. 77% (p = 0.009). However, the percent decline (p = 0.993) and absolute nadir normal value of CA-125 (0-10 vs. 11-35 U/mL) were not predictive of outcome (p = 0.4). CONCLUSIONS: Normal baseline CA125 and normalization of this biomarker after the first cycle of chemotherapy were associated with better survival in high-risk early-stage epithelial ovarian cancer patients.
