Validation of the Prognostic Value of Preoperative Albumin-to-Alkaline Phosphatase Ratio in Patients with Surgically Treated Non-Metastatic Renal Cell Carcinoma.

In conclusion, the high preoperative AAPR was a favorable prognostic factor for surgically treated non-metastatic RCC patients. AAPR also could improve the predictive value of well-established models. The nomogram that incorporates AAPR had a good performance. More prospective studies with a large scale are essential to validate our findings.
