[en] Purpose: The outcome of treatment of 98 over 70-year-old patients with non-Hodgkin's lymphoma (NHL) is presented. Methods and Materials: Analysis of treatment outcome of non-Hodgkin's lymphoma patients age 70 years and more was carried through with special emphasis on fatal complications occurring during treatment. Study patients mainly represented intermediate or high degree of malignancy. Results: Complete response rate (CR) was 54% after combination chemotherapy, 22% after single agent chemotherapy, and 56% after radiotherapy (used for local disease). The overall 5-year survival was 38% for all patients and 57% for CR patients. Stage had a significant effect on both the complete response rate and survival. Survival was also significantly influenced by the malignancy grade. Fifteen patients (15%) died during treatment, many of them had another predisposing disease and markers of poor prognosis. Conclusion: The evaluation of individual prognostic features of each old patient should be completed prior to treatment planning
