By comparing PD-L1 expression (as tumor proportion score, TPS) among the two groups (Supplementary Table S6), the T-without samples showed significantly higher levels of expression of PD-L1 in tumor cells than the T-with samples (positive TPS: 45% and 15%, respectively, p = 0.048), while no statistically significant difference was found with respect to the inflammatory cells (IC) score and the combined proportion score (CPS). The gene discussed is CD274; the disease is neoplasm.
