The time from the diagnosis of the first neoplasm to the appearance of the second one was from 0 to 168 months (mean 61.8 months). The second neoplasm developed in over half the cases (53.1%) after more than 5 years from the first one. The most frequent first neoplasms were: Hodgkin's disease and breast carcinoma, and the most frequent second neoplasm was colonic carcinoma, gastric carcinoma and endometrial carcinoma.
