Cisplatin, VP-16-213 and MGBG (methylglyoxal bis guanylhydrazone) combination chemotherapy in refractory lymphoma, a phase II study

Abstract

In an effort to improve the treatment of patients with refractory or recurrent lymphoma, we developed a protocol using cis-platinum combined with two other agents of known efficacy in these disorders but with differing side effects: VP-16 and MGBG. Twenty-six eligible patients were treated with this regimen. There were 15 men and 11 women with a median age of 54 years (22-73), and performance status of 1 (0-3). Their diagnoses were Hodgkin's disease 5 and non-Hodgkin's lymphoma [NHL] 21 which included 11 with diffuse histocytic lymphoma [DHL]. The median number of chemotherapy regimens was 2 (1-5); 12 also received radiotherapy. Twenty patients are evaluable for response: 15 NHL and 5 Hodgkin's disease. Three patients, all of whom had DHL entered complete remission (20%) with a median time to treatment failure of 7 1/2 months. Six NHL (40%) and one Hodgkin's disease (20%) patients entered a partial remission. There were three early deaths: one due to progressive disease, one to acute respiratory failure, and one with disease status undocumented. Toxicity included leukopenia, thrombocytopenia, anorexia, nausea, vomiting, stomatitis, alopecia, renal failure, profound peripheral neuropathy, and hypersensitivity vasculitis. Treatment was stopped because of the latter two. These agents are non-crossresistant with doxorubicin-containing regimens. The drugs are possibly synergistic and modestly active with moderate to severe toxicity.
