Abstract:
Objective To evaluate the role of nephron sparing surgery in patients with renal cell carcinoma. Methods Retrospectively analyzed a total of 17 patients with renal cell carcinoma treated with nephron sparing surgery between September 1997 and September 2002.Among these patients,2 cases were bilateral asynchronous and multicentric tumor,15 cases were unifocal tumor.2 cases were in imperative indications,6 cases in relative indications,and 9 cases in elective indications.The tumor diameter ranged from 2 cm to 6 cm,all tumor were in T 1 (1997 TNM staging system).15 cases underwent tumor enucleation at 1 cm apart from surgical margin,1 case underwent upper polar nephrectomy,1 case underwent wedged resection.Selected 20 patients matched for age, tumor location and stage who underwent radical nephrectomy at same period for comparison with an average follow-up of 36.4 months. Results The patients were followed up for an average period of 35.2 months (range,3 to 63 months),no surgical complication or local recurrence has been observed,and its long-term cancer-free survival was comparable to that after radical nephrectomy. Conclusions Nephron sparing surgery is safe and effective for the treatment of renal cell carcinoma and indicated for patients with small,localized,often incidental tumors and a normal contra-lateral kidney.
