Non-Hodgkin's lymphoma in the elderly: a guide to drug treatment.

Adverse events are common in the elderly when they undergo potent chemotherapy and the reasons for this are various. Therefore, chemotherapy for elderly patients with non-Hodgkin's lymphoma (NHL) must differ from that for non-elderly patients. Age is one of the poor prognostic factors for NHL and the main reason for this is reduced antitumour effect due to decreased dose and increased adverse effects. However, many of these elderly patients also die from causes other than lymphoma. The usual approach to the treatment of indolent NHL is to use drugs with few adverse effects such as nucleoside analogs. Multidrug therapy is used for intermediate grade NHL and the most commonly used regimen is CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone). In recent years, many clinical trials have been performed in elderly patients with NHL. The results of these trials indicate that a significantly better prognosis is achieved with anthracycline (cytostatic antibiotics) containing regimens. The elderly population will continue to grow and so it is necessary to establish more effective treatment options for NHL in the elderly.
