A retrospective analysis of combination chemotherapy consisting cyclophosphamide, vincristine, prednisolone and procarbazine (C-MOPP) for pretreated aggressive non-Hodgkin lymphoma.

The C-MOPP regimen, consisting cyclophosphamide, vincristine, prednisolone and procarbazine, has been used for treatment of non-Hodgkin lymphoma; however, there are few reports of this therapy against aggressive lymphoma. We performed a retrospective analysis of previously treated 89 patients who had received C-MOPP therapy from 1999 to 2013 at our institution. Median age was 67 (range, 22-81) years. Twenty-eight patients obtained CR, 5 obtained PR, and overall response rate was 37% (33/89). The estimated 1-year overall survival and progression-free survival rates were 61 and 33%, respectively. Major grade > 2 toxicities were leucopenia (55%) and neutropenia (52%). Efficacy and toxicity were in line with other recent studies involving new agents, given that the subjects mainly consisted of elderly outpatients. These data provide a rationale for the use of C-MOPP as a current control treatment arm when the response to new cancer therapy agents is evaluated.
