Objectives:
We attempted to determine whether or not incidental renal cell carcinoma had a better prognosis.
Methods:
We reviewed 53 cases of renal cell carcinoma that had been surgically treated over the periods 1985-1988 and 1989-1993. The form of presentation, stage of the incidental tumors, sex, compromised side and the diagnostic imaging technique utilized were analyzed.
Results:
GI pathology most frequently led to the diagnosis of the tumor. Tumor stages were A or B with a slightly higher prevalence for the incidental tumors. However, the prognosis was not better than that of clinically suspected renal cell carcinoma. The male to female ratio was 1.17:1, the mean age was 63 years, the tumors were frequently right-sided and ultrasound was superior in the diagnosis of incidental tumors.
Conclusions:
No prognostic difference was observed between clinically suspected and incidental renal cell carcinoma of the same tumor stage.
