Fig. 4From: Correlation between schistosomiasis and CD8+ T cell and stromal PD-L1 as well as the different prognostic role of CD8+ T cell and PD-L1 in schistosomal-associated colorectal cancer and non-schistosomal-associated colorectal cancerKaplan-Meier curves for overall survival OS of CRC patients, OS was calculated using the Kaplan–Meier method and analyzed using the log-rank test. A PD-L1 expressing on the immune stroma cells (sPD-L1 positive expressing ≥ 2%) for OS of schistosomal-associated-colorectal cancer patients (SCRC) (p = 0.0040) or for OS of non-schistosomal-associated colorectal cancer patients (NSCRC) (B) (p = 0.1949). C PD-L1 expressing on the tumoral cells (tPD-L1 positive expressing ≥ 2%) for OS of SCRC patients (p = 0.8926) or for OS of NSCRC patients (D) (p = 0.8228)Back to article page
