Abstrakt: We aimed in this study to detect the correlation between PD-L1 and TILs, and their relationship with clinical outcome and survival in Egyptian patients with HGSOC. Immunohistochemical expression of PD-L1, CD4 and CD8 was investigated in 94 HGSOC Egyptian patients. PD-L1 immunoreactivity was detected in 24% of the cases. The lack of tumor PD-L1 expression proved to be an independent predictive factor for better overall survival (OS) (p= 0.01). Moreover, high stromal CD8+ TILs density had a significant impact on better disease-free survival (p=0.007). Patients who showed negative expression of PD-L1 and high intraepithelial CD8+ TILs density lived significantly longer than other patients (p- 0.021). [ABSTRACT FROM AUTHOR]
