Distinct effect of body mass index by sex as a prognostic factor in localized renal cell carcinoma treated with nephrectomy data from a multi-institutional study in Japan

We assessed the prognostic value of body mass index (BMI) in Asian patients with localized RCC who underwent nephrectomy. Methods: A total of 665 patients who underwent nephrectomy for localized RCC were enrolled in the present study and divided into the two BMI groups: i.e., BMI < 25 in 463 (69.6%) and BMI > 25 in 202 (30.4%) patients.
