Partial nephrectomy for small localized renal cell carcinoma
2004
We retrospectively reviewed the records of 54 patients with RCC who underwent partial nephrectomy for the primary lesion between 1992 and 200l. The indications for partial nephrectomy were electiv.e in 43 and imperative in 11 patients. We selected 51 patients with clinical stage Tla who underwent open radical nephrectomy for localized RCC for comparison during the same period. We evaluated the peri- and postoperative complications, disease-free survival rates and changes of renal function in the partial nephrectomy (PN) group, compared to the radical nephrectomy (RN) group. There was no significant difference with regard to pathological findings and clinical outcomes between two groups, except for the amount of intraoperative bleeding. Three patients in the PN group developed postoperative complications, consisting of urine leakage in 2 patients and renal hypertension in 1 patient. The 5-year disease-free survival rates in the PN and RN groups were 90% and 97%, respectively. Local recurrence from the resected area of the renal parenchyma was not found in patients in the PN group. All patients in the PN group maintained satisfactory and stable renal function. In the RN group, renal function slowly deteriorated in 2 patients. Therefore, partial nephrectomy offers cancer control and an acceptable low mortality rate, comparable to those of radical nephrectomy.
