title: Comparative trial of two teniposide-based combination chemotherapy regimens for the treatment of advanced malignant lymphomas.
abstract: One hundred and twenty-three patients with advanced measureable malignant lymphomas resistant to conventional chemotherapy were entered in a prospectively randomized trial of two teniposide (VM-26)-based combination chemotherapy regimens: V-PLAT (VM-26, cisplatin, and prednisone) and V-HEX (VM-26, hexamethylmelamine, and prednisone). Ninety-seven eligible and evaluable patients received protocol therapy. Sixteen percent of the patients had Hodgkin's disease, and 84% had non-Hodgkin's lymphoma. All patients were ambulatory (Eastern Cooperative Oncology Group Performance status 0, 1, or 2), 70% had stage IV disease, 59% had "B" symptoms, and all had failed either two or three previous chemotherapy regimens. Toxicity was mainly hematologic and significantly greater with V-PLAT. Objective tumor responses were seen in nine of 45 patients (20%) treated with V-PLAT (duration, 4-35 + weeks) and in four of 51 patients (8%) treated with V-HEX (duration, 10-65 + weeks). Among the 12 patients with histologically confirmed histiocytic lymphoma treated with V-PLAT, five (42%) experienced objective tumor responses, including two complete responses. Overall median survival was approximately 6 months, with no difference between treatment regimens. Limited antitumor activity of these combination regimens in patients with advanced malignant lymphomas has been demonstrated. However, the objective response rates were not higher than we have previously seen with either VM-26 (22%) or hexamethylmelamine (27%) given in maximum tolerable doses as single agents.
