ABSTRACT
Objective To investigate the efficacy and toxicity of sorafenib in the treatment of advanced renal cell carcinoma. Methods From May 2007 to JUN 2009, 33 patients with advanced renal cell carcinoma were given oral sorafenib 400-600 mg twice daily. There were 23 males and 10 females in the study group. The pathological diagnosis of the primary tumors was clear cell carcinoma in 29 patients, papillary renal cell carcinoma in 2 patients, chromophobe renal cell carcinoma in 1 patient and chromophobe renal cell carcinoma mixed with clear renal cell carcinoma in 1 patient. Fifteen patients had multiple organ metastases and 18 patients had single organ metastasis. The median follow-up time was 29 weeks. Results Four (12%) patients achieved partial remission, 2 (6%) patients achieved progression disease, the remaining 27 (82%) patients achieved stable disease. Complete remission was not observed in the group. Two of the partial remission patients benefited on bone metastases. Common toxicities were skin reaction (85%), diarrhea (46%), erythra (42%), alopecia (36%), oral ulcer (18%) and hypertension (9%). Conclusions Sorafenib could be effective in controlling tumor growth. The overall effectiveness was 12%, the disease control proportion was 94% in this group and its toxicity was relatively minor and well tolerated.
ABSTRACT
Objective To assess the safety and efficacy of abdominal radical nephrectomy and systematic lymph node dissection for treatment of renal carcinoma. Methods A total of 136 patients underwent radical nephrectomy and regional clearance of lymph nodes from July 2004 to June 2008.There were 92 males and 44 females in the study group.Ages ranged from 23 to 81 years,with a mean age of 54 years.The mean tumor diameter was 55 mm (range,15-170 mm).The tumor size detected by CT and MRI was consistent with that detected by B-ultrasound,98 were stage Ⅰ,13stage Ⅱ,12 stage Ⅲ,and 2 stage Ⅳ. Results All 136 cases underwent radical nephrectomy with retroperitoneal lymphadenectomy.All operations were successful without any major complication.The operative time was 90 to 180 min,with an average of 120 min,and blood loss was 20-400 ml,with an average of 50 ml.The pathological diagnoses were as follows: renal cell carcinoma 123 cases (90%), papillary renal cell carcinoma six cases(4%),chromophobic two cases(1.4%),oncocytoma two cases(1.4%),collecting duct two(1.4%),and others three cases(2.2%).Eight cases reported positive lymph nodes.Of the 136 cases,92 cases were T1 N0 M0,11 were T2 N0 M0,10 were T3 N0 M0,eight were T3 N1 M0 and two were T1 N0 M1.Ninety-five cases (70%) were followed-up at six to 40 months (mean,20 months).The one year and three year survival rates were 96% (91/95) and 86% (82/95),respectively.Conclusions Radical nephrectomy with systematic lymph dissection has advantages of accurate staging,effective resecting of renal tumors and preventing recurrence.Radical nephrectomy is an effective method for the treatment of renal carcinoma.
