Hodgkin's Lymphoma

Abstract

Abstract This review focuses on the different treatment options available for the treatment of Hodgkin's disease, with an emphasis on the importance of the long-term sequelae of these therapies. In Section I, Dr. Linch reviews the current status of Hodgkin's disease treatment. Survival rates have improved over the last three decades due both to better initial therapies and associated supportive care and to the success of salvage therapy. Unlike most other malignancies, a similar survival endpoint can be achieved by different means, e.g., intensive initial therapy resulting in a low relapse rate or less intensive initial therapy and more reliance on salvage therapy. Overall survival has thus become a difficult end-point for clinical trials of primary therapy, and the value of disease-free survival as an end-point can also be questioned. Quality-of-life issues are to the fore of clinical decision and include the psychological trauma of relapse and fertility status. Patient choice is increasingly important. The high level of success in treating Hodgkin's disease also means that attention must be focused on the very long term results and in this context the occurrence of second malignancies is a major issue. In Section II, Dr. Gosden with Dr. Tulandi and Dr. Tan review the risks of infertility following radio-therapy and chemotherapy and address the actions that can be taken to overcome this problem, particularly for females and prepubertal boys and girls. Particular attention is paid to the recent developments in ovarian cryopreservation and harvesting immature germ cells. In Section III, Dr. Hancock gives a comprehensive update of the incidence of secondary acute leukemia, non-Hodgkin's lymphoma and solid tumors in a large population of patients treated for Hodgkin's disease. The roles of radiotherapy, chemotherapy and combined modality treatment as risk factors contributing to the development of these secondary malignancies are reviewed. The importance of efforts to prevent late-occurring solid tumors such as lung cancer through smoking cessation programs and early detection by screening for cancers of the breast, thyroid and skin are emphasized.
