Next, we analyzed responder and non-responder gastric cancer patients treated with anti-PD1 (Kim cohort, n = 45) (Figure 5B),31 observing that Ms communicated more with CD8 in the responder (arc count of 0.0446) than in the non-responder group (arc count of 0.0245). This evidence concerns the gene PDCD1 and gastric cancer.
