Kaplan-Meier curves of PFS and OS by treatment strategy of ICI treatment beyond progression with prior immunotherapy. (A,B) The patients who received ICI-based combination therapy achieved more favorable PFS and OS than those of patients who received ICI monotherapy (mPFS 5.1 vs. 3.3 months, P=0.001; mOS 18.4 vs. 13.7 months, P=0.01). mPFS, median progression-free survival; mOS, median overall survival; ICI, immune checkpoint inhibitor.
