PG - 1385-9 LID - 10.1093/annonc/mdv166 [doi] AB - BACKGROUND: The aim of this study was to search for predictive and prognostic factors in patients with metastatic renal cell carcinoma (mRCC) treated with everolimus among the components of PI3K/AKT/mTOR pathway. PATIENTS AND METHODS: In a prospective, one-arm, phase II study, patients with mRCC received everolimus (10 mg/day) using a 30-day cycle. A prospectively planned evaluation of potential biomarkers of PI3K/AKT/mTOR pathway. RESULTS: The median age of the 58 patients enrolled into the study was 60 years (range 41-78 years). In multivariate analysis, it was found that the adverse independent predictors for everolimus therapy were histological grade G1/2 hazard ratio (HR): 2.68 [95% confidence interval (CI) 1.29-5.58, P = 0.0082], increased lactate dehydrogenase (LDH) level before treatment [HR: 2.55 (95% CI 1.30-4.99, P = 0.0064)] and the PIK3CA gene variant rs6443624 (HR: AC + AA versus CC = 2.08, 95% CI 1 11-3.89, P = 0.0254). In multivariate analysis, it was observed that the adverse independent prognostic factors were: elevated corrected calcium level [HR: 4.17 (95% CI 1.66-10.51; P = 0.0024)] and the PIK3CA gene variant rs6443624 [HR: AC + AA versus CC = 1.97 (95% CI 1.02-3.79; P = 0.0421)]. CONCLUSIONS: The PI3KCA gene polymorphism, LDH, and histologic grade can predict the effects of everolimus treatment. The corrected calcium level and the PIK3CA gene variant rs6443624 may be independent prognostic factors. Further investigation is needed to confirm and validate these findings prospectively in other RCC trials. CI - (c) The Author 2015.
