ABSTRACT

Objective To investigate the long-term follow-up results of patients treated with radical nephrectomy for small renal carcinoma.Methods Between January 1992 and June 2004,a total of 56 pa- tients(41 men and 15 women;mean age,54 years;age range,19-71 years)underwent radical nephrectomy for small renal carcinoma.The clinical data and long-term follow-up results of the 56 cases were analyzed ret- rospectively.All the patients were followed by questionnaire;and the 5-and 10-year survival rates were calcu- lated by Kaplan-Meier method.Results None of the patients was found to have metastasis preoperatively. Postoperative pathology showed renal clear cell carcinoma in 44 cases,granular cell carcinoma in 7,and mixed cell carcinoma in 5.Among these cases,ipsilateral adrenal metastasis was found in 1 case,local lymph- aden metastasis in 2,and perirenal fat metastasis in 4.Postoperatively,49 of the 56 patients(87.5%)were followed for 11-155 months with a mean of 71 months.The 5-and 10-year survival rates were 81.7% and 66.9%,respectively.Five patients died of metastasis from renal carcinoma.Conclusions Radical ne- phrectomy for small renal carcinoma has favorable long-term effects,therefore it is an optimal surgical proce- dure for small renal carcinoma.
