The clinicopathologic factors for MSI-H gastric cancers are analyzed by binary logistic regression analysis (backward, stepwise).
MSI-H, high-level microsatellite instability; B, coefficient; SE, standard error; OR, odds ratio; CI, confidence interval; TIL, tumor-infiltrating lymphocytes; HPF, high power field; GC-GP, gastric cancer with gastric mucin predominant type; GC-IP, gastric cancer with intestinal mucin predominant type.
