Abstract:
Objective To improve the capability of diagnosing and treating renal chromophobe cell carcinoma (RCCC) and the recognition of this subtype of renal cell carcinoma (RCC). Methods The clinical data of 15 cases of RCCC (10 men and 5 women) were analyzed.Their age ranged from 47 to 74 years,with a mean of 57 years. Radical nephrectomy was performed in all these cases. Results Postoperative pathological findings confirmed the diagnosis of RCCC.The pathologic TNM stage of RCCC was as follows:pT 1N 0M 0 in 6 cases,pT 2N 0M 0 in 5,pT 3bN 0M 0 in 2,pT 1N 2M 0 in 1 and pT 2N 2M 0 in 1.The pathologic grade of RCCC was G 2 in 10 cases and G 3 in 5.Eleven cases were followed up.During the follow-up of 2 to 31 months (mean, 19 months),1 died of heart attack,1 had local recurrence and 9 were surviving tumor free. Conclusions RCCC is a morphologically distinctive uncommon subtype of RCC.Radical nephrectomy is the first choice for the treatment of RCCC.Compared with other types of RCC at the same stage and of the same grade,RCCC has a better prognosis.
