ABSTRACT
PURPOSE:
In Brazil, National data regarding the epidemiology of renal cell carcinoma (RCC) are scarce. The aim of this study was to describe the demographic, clinical, and pathologic characteristics of RCC diagnosed and treated by members of the SBU - Brazilian Society of Urology. MATERIALS ANDMETHODS:
For this cross-sectional study, data were collected through an on line questionnaire available to the members of the Brazilian Society of Urology (SBU). Between May 2007 and May 2008, voluntary participant urologists collected data on demographic, clinical and pathological characteristics from patients diagnosed with RCC in their practice.RESULTS:
Fifty SBU affiliated institutions contributed with patient information to the study. Of the 508 patients, 58.9 percent were male, 78.9 percent were white, and the mean age was 59.8 years. Smoking history, high blood pressure and a body mass index above 30 kg/m2 were present in 14.8 percent, 46.1 percent and 17.9 percent of the patients, respectively. Abdominal ultrasound and computed tomography were the main diagnostic methods. The majority of the cases were localized tumors and metastasis were presented in 9.5 percent of the patients; 98.4 percent underwent nephrectomy. Clear cell carcinoma was the most common histological type. In comparison with private institutions, stage IV disease was less frequent among patients treated at public health services (P = 0.033).CONCLUSIONS:
RCC in Brazil is more common in white men in their sixth decade of life. Ultrasound is the main diagnostic tool for the diagnosis of clear cell carcinoma and we found that localized disease was predominant. A national registry of RCC is feasible and may provide valuable information.
