Mini-Margin Nephron Sparing Surgery for Renal Cell Carcinoma 4 cm or Less

چکیده
OBJECTIVES To explore the safety and efficacy of mini-margin nephron sparing surgery (NSS) for renal cell carcinoma (RCC) 4 cm or less. METHODS Total of 389 cases of RCC 4 cm or less with normal contralateral kidneys were included in the study, including 135 cases treated by mini-margin NSS, 98 by 1 cm-NSS and 156 by radical nephrectomy (RN). The clinical results were followed-up and comparatively analyzed. RESULTS The mean and median margin width for mm-NSS was 2.2 and 2.0 mm (range 0 to 5). Of them, 112 (83.0%) cases had margins of 3 mm or less, and 26 had margins of 0 mm (19.3%). The mean width of margin for 1 cm-NSS was 11.6 mm (median 12, range 10~15). None of the NSS patients had positive surgical margins. The mean follow-up for mm-NSS, 1 cm-NSS and RN patients was 69, 82 and 82 months, respectively. Three mm-NSS patients, two 1 cm- NSS and four RN patients died of non-cancer related causes. Two mm-NSS patient (1.6%) experienced local recurrence. No distant metastasis was detected in all the patients. The over all 5-year survivals for NSS and RN patients were 100%, 100% and 98.7%, respectively (P = .950). CONCLUSIONS Mini-margin NSS is as safe and effective as 1 cm-NSS and RN in treating early localized RCC 4 cm or less.

Elective nephron sparing surgery for renal cell carcinoma larger than 4 cm.
PURPOSE Elective nephron sparing surgery is established as an alternative to radical nephrectomy for renal cell carcinoma if tumors are small (4 cm or less, stage T1a). We compared outcomes in patients with renal cell carcinoma 4 cm or less (small) vs more than 4 cm (large) who were treated with nephron sparing surgery. MATERIALS AND METHODS Between 1979 and 2006, 618 patients underwent elect...
متن کاملLaparoscopic Nephron-Sparing Surgery for the Small Exophytic Renal Mass
OBJECTIVES Nephron-sparing surgery has emerged as the treatment of choice for the incidentally detected small renal mass, especially those less than 4 cm in size. We describe our technique and experience with the laparoscopic excision of these lesions. METHODS Between June 2001 and October 2003, 20 patients underwent nephron-sparing surgery at our institution. Twenty-one laparoscopic partial ...
متن کاملThe Role of Nephron-Sparing Surgery (NSS) for Renal Tumours >4 cm
For many years, radical nephrectomy (RN) has been the gold standard treatment for renal tumours. However, at present the available evidence supports elective nephron-sparing surgery (NSS) as the standard surgical treatment for renal cortical tumours ≤4 cm (clinical stage T1a). Furthermore, an increasing body of evidence demonstrates that even a minor loss of renal function can increase cardiova...
متن کاملImproved laparoscopic nephron-sparing surgery for renal cell carcinoma based on the precise anatomy of the nephron
The aim of the present study was to investigate a method of laparoscopic nephron-sparing surgery (LNSS) for renal cell carcinoma (RCC) based on the precise anatomy of the nephron, and to decrease the incidence of hemorrhage and urinary leakage. Between January 2012 and December 2013, 31 patients who presented to the General Hospital of the People's Liberation Army (Beijing, China) were treated ...
