Identification of prognostic factors for postoperative recurrence-free survival in T2-stage renal cell carcinoma: a retrospective cohort study

The AST/ALT ratio, Fuhrman grade, SII, sarcomatoid differentiation, and CAIX are independent prognostic indicators for postoperative RFS in T2-stage RCC patients. These factors can facilitate accurate risk stratification and provide a scientific basis for formulating individualized follow-up and treatment strategies. Given the limitations of single-center retrospective design and small sample size, future large-scale prospective multicenter studies are needed to validate these findings.
