The Immune Microenvironment Impacts Survival in Western Patients with Gastric Adenocarcinoma

Expression of CD3+ T cells, CD8+ cytotoxic T cells, CD45RO+ memory T cells, and FOXP3+ regulatory T cells at the invasive margin (IM) and tumor center (TC) has correlated with survival in gastric adenocarcinoma (GA) patients from East Asia, independent of anatomic staging. The reason for improved survival in East Asians compared with Western patients is a subject of debate. This study examined the immune profiles of a cohort of Western patients...
