Renal Cell Carcinoma: Natural History and Chemotherapeutic Experience

Abstract

Eght-four patients with renal cell carcinoma were analyzed retrospectively in order to 1) determine the effectiveness of systemic chemotherapy-hormonal and non-hormmonal, 2) identify the clinical features of renal cell carcinoma that may be important in prognosis and 3) characterize the paraneoplastic features of renal cell carcinoma. Metastatic disease was present at diagnosis in 57 per cent of the cases and developed within 1 year in an additional 19 per cent of the cases were paradoxically associated with a longer survival (20 months median) compared to single-organ metastasis (5 to 11 months median). Paraneoplastic syndromes occurred in up to 40 per cent of patients with variable survival. Metastatic disease was unresponsive objectively to either primary nephrectomy or to a variety of chemotherapy trials.
