Non-Hodgkin's Lymphoma in the Elderly: A Retrospective Evaluation of Toxicity Related to Aggressive vs. Conservative Treatments

The outcome of 70 elderly patients aged 65 years or more (median, 71 years) with non-Hodgkin's lymphoma (NHL) treated between 1973 and 1981 with aggressive (AM) or conservative modalities (CM) was retrospectively evaluated. A significantly higher incidence of lethal and severe toxicity was observed in patients treated with AM than in those treated with CM (32 % vs 3 %, p < 0.01), with 10 % treatment related deaths in the AM group. Only 56 % of the deaths were attributed to NHL; other major causes were treatment-related deaths, infection and cardiac diseases. No significant difference in response and survival was found between AM and CM groups (complete remission rates were 35 % vs 42 %, and 10 year survival rates were 31 % vs 19 %, respectively), but the prevalence of stages III-IV in patients treated with AM makes these results meaningless. Prospective randomized trials with AM vs CM are clearly needed in elderly patients with advanced unfavorable NHL.
