Prognostic value of EndoPredict test in patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative primary breast cancer screened for the randomized, double-blind, phase III UNIRAD trial

Background: The purpose of this study was to evaluate the prognostic value of the multigene EndoPredict test in prospectively collected data of patients screened for the randomized, double-blind, phase III UNIRAD trial, which evaluated the addition of everolimus to adjuvant endocrine therapy in high-risk, hormone receptor-positive, human epidermal growth factor receptor 2 (HER2)-negative early breast cancer. Patients and methods: Patients were classified into low or high risk according to the EPclin score, consisting of a 12-gene molecular score combined with tumor size and nodal status. Association of the EPclin score with disease-free survival (DFS) and distant metastasis-free survival (DMFS) was evaluated using Kaplan–Meier estimates. The independent prognostic added value of EPclin score was tested in a multivariate Cox model after adjusting on tumor characteristics. Results: EndoPredict test results were available for 768 patients: 663 patients classified as EPclin high risk (EPCH) and 105 patients as EPclin low risk (EPCL). Median follow-up was 70 months (range 1-172 months). For the 429 EPCH randomized patients, there was no significant difference in DFS between treatment arms. The 60-month relapse rate for patients in the EPCL and EPCH groups was 0% and 7%, respectively. Hazard ratio (HR) supposing continuous EPclin score was 1.87 [95% confidence interval (CI) 1.4-2.5, P &lt; 0.0001]. This prognostic effect remained significant when assessed in a Cox model adjusting on tumor size, number of positive nodes and tumor grade (HR 1.52, 95% CI 1.09-2.13, P = 0.0141). The 60-month DMFS for patients in the EPCL and EPCH groups was 100% and 94%, respectively (adjusted HR 8.10, 95% CI 1.1-59.1, P &lt; 0.0001). Conclusions: The results confirm the value of EPclin score as an independent prognostic parameter in node-positive, hormone receptor-positive, HER2-negative early breast cancer patients receiving standard adjuvant treatment. EPclin score can be used to identify patients at higher risk of recurrence who may warrant additional systemic treatments.</p

Phase III Study Comparing a Reduced Dose of Cabazitaxel (20 mg/m²) and the Currently Approved Dose (25 mg/m²) in Postdocetaxel Patients With Metastatic Castration-Resistant Prostate Cancer-PROSELICA.

Purpose Cabazitaxel 25 mg/m2 (C25) significantly improved overall survival (OS) versus mitoxantrone ( P 2 (C20) versus C25 in postdocetaxel patients with mCRPC. Methods Patients were stratified by Eastern Cooperative Oncology Group performance status, measurability of disease per Response Evaluation Criteria in Solid Tumors (RECIST), and region, and randomly assigned to receive C20 or C25. To claim noninferiority of C20 (maintenance of ≥ 50% of the OS benefit of C25 v mitoxantrone in TROPIC) with 95% confidence level, the upper boundary of the CI of the hazard ratio (HR) for C20 versus C25 could not exceed 1.214 under a one-sided 98.89% CI after interim analyses. Secondary end points included progression-free survival, prostate-specific antigen (PSA), tumor and pain responses and progression, health-related quality of life, and safety. Results Overall, 1,200 patients were randomly assigned (C20, n = 598; C25, n = 602). Baseline characteristics were similar in both arms. Median OS was 13.4 months for C20 and 14.5 months for C25 (HR, 1.024). The upper boundary of the HR CI was 1.184 (less than the 1.214 noninferiority margin). Significant differences were observed in favor of C25 for PSA response (C20, 29.5%; C25, 42.9%; nominal P < .001) and time to PSA progression (median: C20, 5.7 months; C25, 6.8 months; HR for C20 v C25, 1.195; 95% CI, 1.025 to 1.393). Health-related quality of life did not differ between cohorts. Rates of grade 3 or 4 treatment-emergent adverse events were 39.7% for C20 and 54.5% for C25. Conclusion The efficacy of cabazitaxel in postdocetaxel patients with mCRPC was confirmed. The noninferiority end point was met; C20 maintained ≥ 50% of the OS benefit of C25 versus mitoxantrone in TROPIC. Secondary efficacy end points favored C25. Fewer adverse events were observed with C20

Impact of secondary cytoreductive surgery on survival in patients with platinum sensitive recurrent ovarian cancer: Analysis of the CALYPSO trial

Objective. The role of secondary cytoreductive surgery (SCR) in platinum-sensitive recurrent ovarian cancer (ROC) remains controversial. The overall survival (OS) benefits for surgery reported in observational studies may be due to the selection of patients with better prognosis. Methods. Using data from the CALYPSO trial, OS of patients who had SCR was compared to those treated with chemotherapy alone. Multivariate analyses were performed to adjust for prognostic factors. We also tested for an interaction between baseline prognostic groupings and the benefit of surgery. Results. Of the 975 patients randomised in CALYPSO, 19% had SCR and 80% had chemotherapy alone. OS was longer for the SCR group than for chemotherapy alone (median, 49.9 vs. 29.7 months; adjusted hazard ratio (HR), 0.68; P = 0.004). For patients with SCR, the 3-year OS was 72% for those with no measurable disease, and 28% if residual tumour was larger than 5 cm. Patients with good prognostic features benefited the most from SCR (HR 0.43; P < 0.001). The benefit of SCR was less in patients with poorer prognostic features (test of trend P < 0.001). Conclusion. SCR was associated with improved OS in platinum-sensitive ROC, particularly in patients with favourable prognostic characteristics. However, these findings may be due to selection bias, and hence randomised trials are still essential
