For each patient, histologic expression of PD1 was evaluated separately for TILs and tumor cells, with 136 (81%) of the 168 of patients showing high PD1 expression (>5%) on TILs (expression patterns: 0 [0%]: 19%; 1 + [5–25%]: 33%; 2 + [26–50%]: 40%; and 3 + [51–75%]: 7%) (Table 1). The gene discussed is PDCD1; the disease is neoplasm.
