Abstract
Risk factors, their interrelationship, and prognostic relevance for seminoma stage II disease have been examined. The size of the primary tumor was significantly correlated with the pT category, as was the presence of tumor invasion of small vessels. The pT category was correlated neither with clinical substage nor relapse rate. There was a poorer 3‐year survival for anaplastic seminomas as compared to that of classical seminomas; the difference was not significant. The 5‐year survival for seminomas rich in lymphocytes was better than those of poor lymphocytic infiltration, but this difference also was not significant. No difference in survival or relapse rate was found between HCG‐producing and HCG‐nonproducing seminomas.
