Survival outcomes. A: OS from time of diagnosis for 1088 patients managed at Memorial Sloan Kettering Cancer Center between 1998 and 2009. Outcomes by EFS 24 in patients treated with immunochemotherapy. B: Kaplan-Meier curve of subsequent overall survival after achieving EFS24 (black  =  MER, red  =  Lyon), with expected survival in the age- and sex-matched general population (dashed black  =  MER/United States, dashed red  =  Lyon/France). C: Twenty-four-month landmark Kaplan-Meier OS by POD status. All patients (A). D: Pooled analysis of US and French cohorts. Overall survival since diagnosis.
