    Abstract:
    Several studies have shown that adding rituximab to CHOP (cyclophosphamide, doxorubicin, vincristine, prednisolone) or reducing the interval between chemotherapy cycles from 3 weeks to 2 weeks improves survival in patients with diffuse large B-cell lymphoma (DLBCL). These studies prompted our group (GOTEL) to evaluate prospectively in a pilot study the feasibility and efficacy of R-CHOP-14 in patients with DLBCL. Patients (<70 years) with stage II bulky or stage III or IV DLBCL and no significant comorbidities were included in the study. Rituximab was administered on day 1 before chemotherapy. R-CHOP was given every 14 days. All patients received filgrastim (5 microg/kg) from days 4 to 10. From May 2002 to August 2004, 80 patients were recruited. Median age was 53 years and 58 patients were <60 years. According to the age-adjusted international prognostic index (aaIPI), 13 patients (16%) had low-risk disease, 31 (39%) low-to-intermediate risk, 27 (34%) high-to-intermediate risk and 9 (11%) high-risk disease. Grade 3-4 neutropenia was observed in 15 patients (17.5%) and grade 3-4 infections in 13 patients (16%). After therapy, 58 patients (73%) achieved CR-CRu (95% CI: 55-90%). With a median follow-up of 26 months, progression-free survival (PFS) and overall survival (OS) at 30 months were 72% and 86%, respectively. Administration of R-CHOP-14 is feasible and effective in patients <70 years.
