Occurrence of simian virus 40 (SV40)‐reacting antibodies in sera of some patients with prostatic cancer

Abstract
SV48‐neutralizing antibodies were found in four of 77 sera from patients with pgostatic carcinoma. T antibodies were not detected in any of the sera. The antibody prevalence and the titers of positive sera in prostatic cancer patients were similar to those in sera of bladder cancer patients and of non‐cancerous individuals.
