OBJECTIVEThe aim of this study is to analyse the efficacy and toxicity of CEOP regimen in the treatment of non-Hodgkin's lymphoma (NHL).

METHODSFrom January 1995 to December 2000, 121 patients with NHL were treated by CEOP regimen with or without radiotherapy for the involved field. The clinical characteristics, response, toxicity and long-term survival results were analysed retrospectively.

RESULTSOf these 121 patients, 83 (68.6%) had B-cell NHL and 38(31.4%) peripheral T or NK-cell NHL; 55. 4% (67/121) had early disease (stage I or II), and 89.3% (108/121) had IPI score 0-2. The median age was 53 years (range: 7-79 yr). All patients were treated by CEOP regimen (totally, 471 cycles) with or without radiotherapy. The overall response (OR) rate in this series was 90.9% (110/121) with a complete remission (CR) rate of 71.9% (87/121); whereas the response rate of chemotherapy alone was 88.4% (107/121) with a CR rate of 67.8% (82/121). Major toxicity consisted of grade III-IV myelosuppression (11.9%), neutropenia (1.9%) and thrombocytopenia and anemia (1.1%). Alopecia was observed in 46.3%. However, cardiotoxicity was mild and reversible. Median follow-up duration in this series was 63 months (range: 2-116 months). The overall 1-, 3- and 5-year survival rate was 84.8%, 62.7% and 55.9%, respectively, with a median survival time of 85 months (2-118 months).

CONCLUSIONOur data show that CEOP regimen combined with or without radiotherapy for the involved field is effective and well tolerated by the patients with non-Hodgkin's lymphoma.
