CRP and renal pelvis/ureter urothelial carcinoma: Several studies reported the incorporation of SIR-related hematological biomarkers, such as CRP, NLR, albumin, and lymphocyte and platelet count, with a predictive model for survival outcomes in MIBC [37, 38, 46] or UTUC [50, 55, 57], improved predictive accuracy of the model, and consequently discriminated patients well according to risk stratification.
