RADIATION-INDUCED CHANGES IN LONG-TERM SURVIVORS OF CHILDHOOD-CANCER AFTER TREATMENT WITH RADIATION-THERAPY

This article has provided an account of the delayed effects after successful treatment for childhood cancer. Particular emphasis has been placed on sequelae induced by radiation therapy. Chemotherapy-related complications that may simulate or aggravate these sequelae also are recorded. The alterations induced by radiation therapy and chemotherapy are not limited to the organs and tissues described in this article. Subtle, and at times psychologically devastating, sequelae also may be encountered (eg, sterility due to radiation and chemotherapeutic effects on the gonads). However, an attempt has been made only to identify those complications that may be more readily detected by means of radiographic studies. It is recommended that ongoing surveillance of the long-term successfully treated childhood cancer survivor be conducted in order to detect such complications. Early detection will assist in implementing appropriate treatment, minimizing delayed effects, and maximizing the quality of life. Periodic radiographic studies of previously radiated areas at regular intervals therefore appears appropriate. © 1994 W. B. Saunders Company. All rights reserved.
