No significant correlations were observed between %PD-1+CD8+ TIL and IHC scores; however, PD-1hiCD8+ TIL (FACS) are associated with tumor size, in situ carcinoma, menopausal status, PD-1hiCD4+ TIL, and PD-L2 status (Table S6B in Supplementary Material). This evidence concerns the gene PDCD1LG2 and in situ carcinoma.
