OBJECTIVE To evaluate the efficacy of rituximab combined with CHOP-like regimen with or without IFN in patients newly diagnosed diffuse large B-cell Non-Hodgkin＇s lymphoma （DLBCL）.METHODS From January 2003 to July ...OBJECTIVE To evaluate the efficacy of rituximab combined with CHOP-like regimen with or without IFN in patients newly diagnosed diffuse large B-cell Non-Hodgkin＇s lymphoma （DLBCL）.METHODS From January 2003 to July 2008, 51 patients received CHOP-like chemotherapy （cyclophosphamide 750 mg/m2, epirubicin 80 mg/m2, vindesine 2.8 mg/m2 on day 1, and prednisolone 100 mg/day on day 1 to day 5）. Thirty-one patients received CHOPR-like treatment （rituximab 375 mg/m2 1 day before CHOP-like chemotherapy）. Twenty patients received CHOP-like regimen in combination with peginterferon （pegIFN） （1μg/kg on day 5） and rituximab （on day 6）.RESULTS -The CR （complete remission） rate in the CHOPR-like （with or without pegIFN） group and in the CHOP-like group was 78.4% and 45.1% （P = 0.005）, respectively. The estimated mean time of overall survival （OS） in the CHOPR-like group and CHOP- like group was 58.7 ± 2.8 and 36.4 ±3.4 months, respectively （P = 0.002）. The rates of CR and OR （overall remission） in CHOPR- like with IFN arm were 85.0% and 95.0%, and the rates of those in CHOPR-like without IFN arm were 74.2% and 87.0% （P 〉 0.05）. The estimated mean time of 4-year-PFS （progression- free survival） in CHOPR-like with IFN arm and in CHOPR-like without IFN arm was 62.9 ±3.0 months and 51.0 ± 4.6 months （P = 0.092）, respectively. In the CHOPR-like with IFN arm, no patient relapsed after achieving CR, while the estimated rate of 4-year- DFS （disease-free survival） in the patients who reached CR in the CHOPR-like without IFN arm was （63.4 ± 19.3）% （P = 0.061）. CONCLUSION Rituximab combined with CHOP-like chemotherapy improved the prognosis of DLBCL patients. The IFN may help to improve the quality and duration of response of DLBCL patients treated with rituximab and CHOP-like regimen.展开更多
