Prophylactic effects of perioperatively administered neocarzinostatin in renal cell carcinoma

Eighteen patients with stages I to III renal cell carcinoma were treated with Neocarzinostatin before, during and after nephrectomy. The mean cumulative dose of Neocarzinostatin was 18.0 mg. With a minimum follow-up period of 57 months (4.8 years), two of 18 patients developed metastasis and both were dead. Of 17 control patients who were observed for 72 months (6.0 years) or more, ten had recurrent disease and eight of them were dead. The 5-year survival rates were 94% for patients who received Neocarzinostatin and 62% for control patients. There was a statistical difference in survival between these two groups. Neocarzinostatin seems to be effective in the prevention of postoperative recurrence of renal cell carcinoma.
