title: Late Effects Following Treatment of Hodgkin Lymphoma During Childhood and Adolescence. Results of the Hodgkin Lymphoma Late Effects Research Project.
abstract: Survival rates have been excellent in patients treated for Hodgkin lymphoma (HL) during childhood and adolescence. Unfortunately, severe treatment related late effects have been observed. It was therefore an important aim of the cooperative pediatric HL therapy studies in Germany to reduce the number of late effects without jeopardizing the excellent treatment results. Progress and relapses of HL were analyzed to obtain important information for the future salvage therapy. All late effects were documented and their etiologies analyzed. Information obtained from bacterial infections and late deaths following splenectomy were used to inform patients at risk and their local physicians about necessary preventive measurements. Procarbazine was recognized as major gonadotoxic agent in boys and eliminated successively from the treatment regimens. Parenthood was normal in female patients when compared to the German female population documenting normal ovarian function except in patients with pelvic radiation. Radiation was the most important risk factor for thyroid diseases, cardiac late effects and subsequent malignant neoplasms, especially thyroid and breast cancer. A special screening program was initiated for women with chest radiotherapy, since they had a high risk of breast cancer already at a young age. The results of the HL Late Effects Research Project are important for the aftercare of patients and for the design of future HL treatment regimens.
