Figure 2.

Kaplan–Meier plots of progression-free survival and overall survival stratified by BLN (BLN ⩽ 5/BLN > 5) and TMB (TMB ⩽ 12Muts/Mb/TMB > 12Muts/Mb) in treatment-refractory advanced gastric cancer patients receiving PD-1 inhibitor. (a) Progression-free survival; (b) Overall survival.

Patients were stratified into three subgroups: BLNlowTMBhigh (n = 8), BLNhighTMBhigh or BLNlowTMBlow (n = 31) and BLNhighTMBlow (n = 15). The progression-free survival and overall survival was the best for BLNlowTMBhigh group and the worst for BLNhighTMBlow group (both p < 0.05).BLN, baseline lesion number; PD-1, programmed cell death-1; TMB, tumor mutation burden.
