RESUMO
BACKGROUND: The results of CHOP-21 (cyclophosphamide, doxorubicin, vincristine and prednisone given every 21 days) for the treatment of aggressive B-cell lymphoma have recently been improved by the addition of rituximab and by increasing the dose density. R-CHOP-14 combines these two approaches. PATIENTS AND METHODS: We present our experience with R-CHOP-14 in a retrospective single-centre review of 50 patients consecutively treated for aggressive B-cell lymphoma. RESULTS: The median age was 59 years and 48% of patients were >60 years. Stage III-IV was present in 62% of the patients and international prognostic index was high-to-intermediate risk or high risk in 32% of the patients. Toxicity was mainly haematological, with grade 3-4 neutropenia observed in 32% and febrile neutropenia in 18%. Other relevant toxicities were peripheral neuropathy in 45% (grade 3 in 4%) and cardiac dysfunction grade 3 in 7.5%. After therapy, 82% of the patients achieved complete response or unproved complete response. With a median follow-up of 30 months, 3-year event-free survival and overall survival were 67% and 82% respectively. CONCLUSIONS: In our experience the combination of RCHOP- 14 is highly effective in patients with aggressive B-cell lymphoma. However special attention must be paid to the control of early and late toxicities (AU)
