Abstract

OBJECTIVES:

To describe the characteristics, forms of presentation and therapeutic management in transplanted patients treated for renal tumor in our hospital.

MATERIALS AND METHODS:

We conducted a retrospective analysis of 10 patients who underwent renal transplantation and developed a renal tumor between January 2010 and June 2014. The collection of data was carried through history electronic medical records of our hospital (Intranet).

RESULTS:

During the study period, 796 patients were treated for a kidney tumor in our hospital; 10 of these cases occurred in renal transplant patients. 90% were men. Average age was 40 years. Average time kidney transplantation/tumor was 14 years. 80% of the tumors were incidental. 90% had localized disease. Half of the patients (n=5) included in this series had one or more tumors in the native kidneys, while the other 50% had a tumor in the graft. All patients (n=5) with native kidney tumor underwent laparoscopic radical nephrectomy. Graft tumor: renal explant (n=1), partial nephrectomy conventional route (n=3) and active surveillance (n=1). 46% (n=6) of the tumors corresponded to clear cell renal carcinoma variety. The other 7 (54%) tumors corresponded to papillary variety. The average follow-up of patients was 14.7 months. Surgical patients (n=9) underwent 88.8% (n=8) developed favorably.

CONCLUSIONS:

Renal tumors in transplant patients are characterized by incidental diagnosis and a higher proportion of papillary types. The treatments for these patients are similar to the general population.
