Pyroptosis impacts the prognosis and treatment response in gastric cancer via immune system modulation.

ABSTRACT: Pyroptosis plays a vital role in the development of cancers; however, its role in regulating immune cell infiltration in tumor microenvironment (TME) and pyroptosis-related molecular subtypes remain unclear. Herein, we comprehensively analyzed the molecular subtypes mediated by the pyroptosis-related genes (PRGs) in gastric cancer (GC). Three pyroptosis patterns were determined with distinct TME cell-infiltrating characteristics and prognosis. Principal component analysis was performed to establish the pyroptosis score. The high pyroptosis score group was featured by increased activated CD4+ T cell infiltration, better prognosis, elevated tumor mutation burden, higher immune and stromal scores, and enhanced response to immunotherapy. However, the low pyroptosis score group was characterize
