PDCD1 and neoplasm: Multivariate logistic regression analyses showed that LAG‐3 positivity (odds ratio [OR]: 0.276; 95% CI: 0.091–0.841; p = 0.024), PD‐1 positivity (OR: 0.351; 95% CI: 0.125–0.986; p = 0.047), tumor grade 2 (OR: 0.294; 95% CI: 0.092–0.945; p = 0.040), and tumor grade 3 (OR: 0.136; 95% CI: 0.032–0.574; p = 0.007), were independent predictive factors for TCF‐1 expression (Table 2).
