[Incidental renal cancer in young adults: clinical and histopathological findings].

OBJECTIVE to evaluate the clinical and pathological renal cancer (CR) characteristics in our series of tumours, analyzing its impact in the group of age less than 40 years. MATERIAL AND METHODS We studied 294 patients with CR. The pathologic characteristics were analyzed and DNA ploidy pattern of the surgical pieces were done in 252 patients. The patients were divided in two groups based on age, greater or less to 40 years, well then clinical and pathologic characteristics were compared between. RESULTS Of all patients, 26 of 294 patients (8,94%) were included in the young age group (less to 40 years). We did not found differences between both groups comparing stage, tumoral volume, treatment realized or DNA ploidy pattern, but in nuclear grade with more aggressive tumours in young people (p=0,0018), without differences in recurrence-free survival or actuarial disease specific survival rate. CONCLUSIONS The findings in our study indicate that the natural history and outcome of the RC is similar in both older and younger patients. Therefore, in our opinion, the management of CR in young people should be established with independence of the age.
