Chemotherapy for advanced, recurrent or metastatic endometrial carcinoma.

ABSTRACT:

Background

Although endometrial adenocarcinoma is a common gynaecological cancer, a comparatively small proportion of patients present with, or develop, recurrent or advanced disease. However, for those women whose disease does progress or recur the prognosis is poor and the best treatment is yet to be identified. Co-morbidity, including obesity and cardiac disease, and concerns over toxicity have prevented more extensive studies of cytotoxic chemotherapy, although there are a number of active agents.

Objectives

To assess any benefits or adverse effects of cytotoxic chemotherapy in women with advanced, recurrent or metastatic endometrial adenocarcinoma.

Search methods

Systematic searches of MEDLINE, EMBASE, CENTRAL and the Cochrane Gynaecological Cancer specialist trials register were conducted to identify all eligible randomised controlled trials (RCTs).Databases were searched from 1966 to January 2012. Literature searches were supplemented with searches of relevant trials registers and conference proceedings.

Selection criteria

RCTs comparing chemotherapy versus another intervention (including different chemotherapy) in advanced disease were considered. Trials of adjuvant treatment or for sarcomatous tumours were excluded.

Data collection and analysis

Data were extracted from the papers by review authors and authors of included studies contacted for further information.

Main results

Fourteen eligible trials, which recruited patients between 1974 and 2005, were identified, eight of which compared 'more' with 'less' chemotherapy. Results from these eight trials, including 1519 patients, showed that treatment consisting of 'more' chemotherapy was associated with longer overall survival (OS) (hazard ratio (HR) 0.86; 95% confidence intervals (CI) 0.77 to 0.96; P = 0.005) and with longer progression-free survival (PFS) (n = 1526; HR 0.82; 95% CI 0.74 to 0.90; P < 0.0001). However, serious acute toxicities were more common in women randomised to the more-intense chemotherapy regimens.There was no evidence to suggest that any particular doublet chemotherapy was better (or worse) than any other, or that any single-agent chemotherapy was better (or worse) than another; however, data for these two comparisons were limited. There were no comparative trials of chemotherapy with endocrine therapy or best supportive care alone.

Authors' conclusions

This review suggests that more-intense chemotherapy regimens may improve both OS and PFS for women with advanced or recurrent endometrial cancer. However, owing to inconsistencies between cytotoxic drug combinations that have been assessed in randomised trials to date, the optimum regimen has still to be defined. Future trials should aim to include measures of quality of life (QoL) and symptom control in addition to survival and progression outcomes.

Project description:ObjectiveIn the double-blind, phase III, placebo-controlled RUBY randomized clinical trial, dostarlimab plus carboplatin-paclitaxel significantly increased survival among patients with primary advanced or recurrent endometrial cancer (EC). We conducted a cost-effectiveness analysis of dostarlimab in combination with chemotherapy in these patients stratified by mismatch repair-deficient (dMMR) and mismatch repair-proficient (pMMR) subgroups from the perspective of a United States payer.Materials and methodsA Markov model with three states was employed to simulate patients who were administered either dostarlimab in combination with chemotherapy or chemotherapy based on the RUBY trial. Quality-adjusted life-years (QALYs), lifetime costs, and incremental cost-effectiveness ratio (ICER) were calculated with a willingness-to-pay (WTP) threshold of $150,000 per QALY. Both univariate and probabilistic sensitivity analyses were carried out to explore the robustness of the model.ResultsIn dMMR EC, the combination of dostarlimab and chemotherapy achieved an additional 5.48 QALYs at an incremental cost of $330,747 compared to chemotherapy alone, resulting in an ICER of $60,349.30 per QALY. In pMMR EC, there were 1.51 additional QALYs gained at an extra cost of $265,148, yielding an ICER of $175,788.47 per QALY. With a 15.2% discount on dostarlimab, the ICER decreased to $150,000 per QALY in the pMMR EC. The univariate sensitivity analysis revealed that the cost of dostarlimab, utility of progression-free survival (PFS), and progressive disease (PD) had the most significant impacts on the outcomes. Probabilistic sensitivity analysis revealed that dostarlimab had a 100% likelihood of being considered cost-effective for patients at a WTP threshold of $150,000 per QALY for dMMR EC, whereas this likelihood was only 0.5% for pMMR EC.ConclusionDostarlimab in combination with chemotherapy was cost-effective for primary advanced or recurrent dMMR EC from the perspective of a United States payer at a WTP threshold of $150,000 per QALY, but not for pMMR EC. Lowering the prices of dostarlimab could potentially enhance the cost-effectiveness of treatment for pMMR EC.

Project description:BackgroundStandard first-line chemotherapy for endometrial cancer is paclitaxel plus carboplatin. The benefit of adding pembrolizumab to chemotherapy remains unclear.MethodsIn this double-blind, placebo-controlled, randomized, phase 3 trial, we assigned 816 patients with measurable disease (stage III or IVA) or stage IVB or recurrent endometrial cancer in a 1:1 ratio to receive pembrolizumab or placebo along with combination therapy with paclitaxel plus carboplatin. The administration of pembrolizumab or placebo was planned in 6 cycles every 3 weeks, followed by up to 14 maintenance cycles every 6 weeks. The patients were stratified into two cohorts according to whether they had mismatch repair-deficient (dMMR) or mismatch repair-proficient (pMMR) disease. Previous adjuvant chemotherapy was permitted if the treatment-free interval was at least 12 months. The primary outcome was progression-free survival in the two cohorts. Interim analyses were scheduled to be triggered after the occurrence of at least 84 events of death or progression in the dMMR cohort and at least 196 events in the pMMR cohort.ResultsIn the 12-month analysis, Kaplan-Meier estimates of progression-free survival in the dMMR cohort were 74% in the pembrolizumab group and 38% in the placebo group (hazard ratio for progression or death, 0.30; 95% confidence interval [CI], 0.19 to 0.48; P<0.001), a 70% difference in relative risk. In the pMMR cohort, median progression-free survival was 13.1 months with pembrolizumab and 8.7 months with placebo (hazard ratio, 0.54; 95% CI, 0.41 to 0.71; P<0.001). Adverse events were as expected for pembrolizumab and combination chemotherapy.ConclusionsIn patients with advanced or recurrent endometrial cancer, the addition of pembrolizumab to standard chemotherapy resulted in significantly longer progression-free survival than with chemotherapy alone.

Project description:BACKGROUND:Endometrial cancer is a cancer of the lining of the womb and worldwide is the seventh most common cancer in women. Treatment with hormones is thought to be beneficial in patients with endometrial cancer. OBJECTIVES:To assess the indications, effectiveness and safety of hormone therapy for advanced or recurrent epithelial endometrial cancer. SEARCH STRATEGY:We searched the Cochrane Gynaecological Cancer Group Trials Register, MEDLINE, EMBASE up to May 2009 and and CENTRAL (Issue 2, 2009). We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies, and contacted experts in the field. SELECTION CRITERIA:Randomised controlled trials (RCTs) that studied hormonal therapy in adult women diagnosed with advanced or recurrent endometrial cancer. DATA COLLECTION AND ANALYSIS:Two review authors independently abstracted data and assessed risk of bias. Comparisons were restricted to single-trial analyses so we did not synthesise data in meta-analyses. MAIN RESULTS:We found six trials (542 participants) that met our inclusion criteria. These trials assessed the effectiveness of hormonal therapy in women with advanced or recurrent endometrial cancer as a single agent, as part of combination therapy and as low versus high dose. All comparisons were restricted to single-trial analyses, where we found no evidence that hormonal therapy as a single agent or as a combination treatment prolonged overall or five-year disease-free survival of women with advanced or recurrent endometrial cancer. However, low-dose hormonal therapy may have had a benefit in terms of overall and progression-free survival (PFS) compared to high-dose hormonal therapy (HR 1.31, 95% CI 1.04 to 1.66 and HR 1.35, 95% CI 1.07 to 1.71 for overall and PFS, respectively). AUTHORS' CONCLUSIONS:We found insufficient evidence that hormonal treatment in any form, dose or as part of combination therapy improves the survival of patients with advanced or recurrent endometrial cancer. However, a large number of patients would be needed to demonstrate an effect on survival and none of the included RCTs had a sufficient number of patients to demonstrate a significant difference. In the absence of a proven survival advantage and the heterogeneity of patient populations, the decision to use any type of hormonal therapy should be individualised and with the intent to palliate the disease. It is debatable whether outcomes such as quality of life, treatment response or palliative measures such as relieving symptoms should take preference over overall and PFS as the major objectives of future trials.
