The incidence of second malignancies was assessed by retrospectively analyzing data from previous studies in well-defined and closely followed patient cohorts. After a median follow-up of more than 6 years following MOPP (mechlorethamine/vincristine/procarbazine/prednisone) chemotherapy with or without radiotherapy, 5% of patients with Hodgkin's disease developed second primaries, 60% of which were leukemias. Melphalan caused a 3% leukemia rate among 1129 patients with ovarian cancer who were followed for a median period of 4 years. No leukemia was observed among 1132 breast cancer patients treated with adjuvant CMF (cyclophosphamide/methotrexate/5-fluorouracil) after a median follow-up of 7.5 years. Long-term, comprehensive studies are needed to improve the current knowledge and the prognosis of patients with second primary neoplasms.
