CD8A and neoplasm: As shown in Table 3, parenchymal CD8+ T‐cell density at the invading tumor edge (hazard ratio [HR] 0.19, 95% confidence interval [CI] 0.05‐0.72, P = 0.01), age (HR 0.26, 95% CI 0.07‐0.98, P = 0.04), cN stage (HR 0.17, 95% CI 0.03‐0.95, P = 0.04), pT stage (HR 6.6, 95% CI 1.49‐29.96, P = 0.01) and pN stage (HR 6.47, 95% CI 1.40‐29.86, P = 0.01) were independent prognostic factors for OS.
