Influence of body mass index and smoking on the long-term survival of patients with renal cell cancer.

Background: Smoking and obesity are known risk factors for renal cell carcinoma (RCC). We determined the influence of smoking, body mass index (BMI), and symptoms on the survival of patients with RCC.

Patients And Methods: In this retrospective study, the relative overall survival (OS) up to 25 years was calculated among 948 Finnish patients with RCC diagnosed between 1964 and 1997 using a Bayesian univariate analysis and the life-table method.
