[Insufficient understanding of second tumors after childhood neoplasms in Switzerland].
Second malignancy after childhood neoplasms is a well-known complication. However, frequency differs considerably according to the types of primary neoplasm and the specifics of therapy. Ten patients with a second malignancy after being cured of the primary tumor are described. There were 2 patients with acute lymphoblastic leukemia, one with non-Hodgkin's lymphoma, and one with breast cancer after Hodgkin's disease. Two patients with heritable retinoblastoma developed osteosarcomas in the irradiation field after a latent period of 7 and 14 years respectively. There was another osteosarcoma in a Wilms' tumor survivor. One patient with acute lymphoblastic leukemia developed a secondary AML 10 years after achieving initial remission, and a meningioma was diagnosed in another patient with cured acute lymphoblastic leukemia. One patient died of peritoneal sarcomatosis of unknown origin 20 years after the diagnosis of acute myeloid leukemia. All patients received radiotherapy for the primary neoplasms. Secondary neoplasms in other patients were probably missed because they occurred in adulthood when the patients were transferred to other medical centres. It is impossible to trace these patients because central registration of patients with neoplasms is lacking. It is therefore important to establish a central cancer registry for the whole of Switzerland. Second malignancy after childhood cancer is not a rare event and requires long-term follow-up of patients with neoplasms.
