Abstract
The objective of this study is to evaluate the long-term efficacy and safety of rituximab combined with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) in Chinese patients with newly diagnosed diffuse large B cell lymphoma (DLBCL). The study comprised a retrospective analysis of patients treated at a single center. Patients received four to six infusions of rituximab (375 mg/m2 per dose) on day 1 of each cycle of CHOP chemotherapy. CHOP was initiated on day 3 of each cycle; cycles were repeated at 21-day intervals. A total of 82 patients with a median age of 45 years (range 18–76 years) was included. The overall response (OR) and complete response (CR) rates were 90.2 and 70.7%, respectively. The estimated 5-year progression-free survival (PFS) and overall survival (OS) rates were 56.4 ± 8.3% and 74.1 ± 7.4%, respectively. Patients with International Prognostic Index (IPI) scores ≤2 had significantly higher OR, CR, PFS, and OS rates (p = 0.01, p = 0.02, p = 0.01, p < 0.001, respectively) compared with patients with IPI scores >2. The hematologic toxicity was mild. Five patients with a history of chronic hepatitis B experienced a reactivation of viral hepatitis. The rituximab–CHOP combination was effective and well tolerated in Chinese patients with newly diagnosed DLBCL.
