Prognostic Value of Testing PD-L1 Expression After Radical Cystectomy in High-risk Patients

We have confirmed the high heterogeneity of PD-L1 cell type-dependent expression, with the resulting divergent outcomes. Ultimately, no clear statement about PD-L1 expression as a prognostic biomarker for further AC after RC could be made, although PD-L1 expression on immune cells seemed to have the greatest effect in predicting the outcome.
