Abstract:
Objective Multicystic renal cell carcinoma(MCRCC)appears to be a distinct subtype of renal cell carcinoma with characteristic gross and microscopic features.To explore the clinical and pathological features of MCRCC in order to find out its difference from renal clear cell carcinoma undergoing cystic change(RCCCC),and to propose prognosis criteria for therapeutic modalities.Methods From 1999 to 2003 32 patients were identified to have renal carcinoma,and they received radical or partial nephrectomy in the authors' institution.The pathological diagnosis was either MCRCC(n=21)or renal cell carcinoma associated with features of cystic changes(n=11).All specimens were reviewed histologically by two independent pathologists.The clinicopathologic and follow-up prognosis data on MCRCC and RCCCC were collected for study.Results 21 patients with MCRCC were 17 men and 4 women.The mean age at the time of surgery was 49 years(range 37 to 67 years).15 MCRCC patients with follow-up data were still alive with a mean follow-up time of 61 months(ranged 31 to 73)and no evidence of recurrence and metastasis was discovered.The mean survival time for 7 of the 11 patients with RCC was 32 months(ranged 18 to 63).There was significant difference in survival time between the two groups(P
