Gastric cancer (GC) is one of the common types of cancer in Vietnam. Over 50% of GCs are diagnosed at an unresectable stage. Deficiency in mismatch repair proteins (MMR) leading to microsatellite instability (MSI-H) is a crucial prognostic factor currently under investigation in these patients. This study aimed to determine the rate of MMR protein expression and its correlation with clinical characteristics, histopathological features, and overall survival in unresectable GC patients.
