Kaplan-Meier-Survival analysis for PFS and OS after 1st and salvage PRRT. Kaplan-Meier-Survival Analysis for PFS and OS. Every patient showed initial response to four cycles of 177Lu-DOTATATE and later progression prior to salvage PRRT. Median PFS after the start of PRRT was 33 months (a). The median PFS after start of salvage therapy was 6 months (b) median follow-up time: 25 months; 3 patients lost to follow-up, 8 patients censored). Median OS was not reached during a median follow-up of 71 months from start of 1st PRRT cycle (c) and 25 months from the start of salvage PRRT (d)
