Furthermore, PD-L1 expression on TILs was found in 8 out of 32 patient specimens (25.0%), and on tumor infiltrating macrophages, in 9 out of 32 patient specimens (28.1%), and patients with PD-L1 expression on TILs showed an improvement in survival prognosis (29 months vs. 6 months, p = 0.002) [89]. The gene discussed is CD274; the disease is neoplasm.
