Results of a post hoc 4-year analysis are reported, including progression/recurrence-free survival 2 (PRFS2).Patients were randomly assigned 1:1 to pembrolizumab 200 mg or placebo intravenously every 3 weeks (part 1). RFS was the primary end point; DMFS was secondary. Patients with recurrence following placebo or 17 cycles of pembrolizumab could cross over to or be rechallenged with pembrolizumab (part 2).Median follow-up (n = 976) was 52.8 months (range, 39.4-64.8).
