We devised a new epirubicin-based combination chemotherapy (Epi-COP) regimen for the patients with elderly non-Hodgkin's lymphoma and have treated 30 patients aged 66 years and older who had measurable diseases. In Epi-COP therapy, epirubicin was used as a substitute for doxorubicin in the CHOP regimen, and some dose modifications were made for the other agents. Combined modality treatment (CMT; chemotherapy plus radiotherapy) was adopted for 9 patients with localized disease. Complete response was obtained in 21 of all the 30 patients (70%), 8 in 9 (89%) of the CMT group and 13 in 21 (62%) of the patients with chemotherapy only (chemotherapy group). The median follow up time is 350 days, ranging from 2to 77 months. The 2 year survival rate was 56% in all patients, 67% in the CMT group and 52% in the chemotherapy group. Granulocyte colony-stimulating factor (G-CSF) was administered when the leucocyte count decreased below 2, 000/μl, and 16 patients received it in the first course. The regimen could be repeated every three weeks in most cases. Although we encountered two early deaths, the overall toxicity level seemed to be acceptable. Even when we take account of the small number of patients and the short observation period, it might be concluded that Epi-COP was effective in inducing a good remission rate with moderate toxic effect in elderly patients with non-Hodgkin's lymphoma and CMT should be adopted if it is localized. A randomized comparative study with the CHOP regimen is necessary.
