[Effect of THP-CVP regimen for elderly patients with malignant lymphoma]

Between April 1990 and June 1992, a multicenter clinical trial of chemotherapy regimens was performed with patients, aged 65 years or more, suffering from malignant lymphoma. The total number of patients was 38 included 30 initial cases (median age: 72) and 8 relapsed cases (79). The chemotherapy regimen, administered every 3 weeks, included pirarubicin (30 mg/m2; day 1), cyclophosphamide (500 mg/m2; day 1), vindesine (1.5 mg/m2; day 1), and prednisolone (40 mg/m2; days 1-5) for the initial cases, and etoposide (100 mg/m2; days 1-5) in addition for relapse cases. The complete response and partial response rates were 50.0% and 40.0% in initial cases, respectively, and 50.0% and 0% in relapsed cases, respectively. The 50% survival period was 25.9 months in initial cases and 18.0 months in relapse cases. There were no serious side effects related to the regimens. Performance status deteriorated in only one case after chemotherapy. We concluded that the chemotherapy regimens were useful and safe for elderly patients with malignant lymphoma.
