Objective: The aim of this study is to analyse the efficacy and toxicity of CEOP regimen in the treatment of non-Hodgkin's lymphoma (NHL).
Methods: From 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.
Results: Of 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).
Conclusion: Our 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.
