Abstract
PURPOSE: To develop a reliable prognostic model for patients with metastatic renal cell carcinoma (RCC) based on features readily available in common clinical settings.



PATIENTS AND METHODS: A total of 197 patients with RCC who underwent nephrectomy and immunotherapy from 1995 to 2004 were retrospectively reviewed. Their mean age was 55.1+/-11.8 yrs (24-83 yrs) and mean survival time from metastasis was 22.6+/-20.2 mos (3-120 mos). The impact of 24 clinicopathological features on disease specific survival was investigated.



RESULTS: On univariate analysis, constitutional symptoms, sarcomatoid differentiation, tumor necrosis, multiple primary lesions, liver metastasis, Eastern Cooperative Oncology Group Performance Status (ECOG-PS), thrombocytosis, alkaline phosphatase, hematocrit, T stage, N stage, and nuclear grade had significant influence on survival (p<0.05). Multivariate analysis revealed the following features associated with survival: sarcomatoid differentiation [hazard ratio (HR)=2.99, p<0.001], liver metastasis (HR=2.09, p=0.002), ECOG-PS (HR=1.95, p=0.005), N stage (HR=1.94, p=0.002), and number of metastatic sites (HR=1.76, p=0.003). An individual prognostic score was defined as the sum of the weight of these features. According to prognostic scores, patients could be subdivided into 3 groups: low risk (score 0), intermediate risk (score 1 or 2), and high risk (score >or= 3).



CONCLUSION: A comprehensive prognostic stratification model was developed to predict survival and stratify patients for prospective clinical trials.
