Continuous cyclophosphamide, doxorubicin, vincristine, and prednisolone. A new, innovative protocol for diffuse aggressive lymphomas.
One hundred eight patients with aggressive non-Hodgkin's lymphoma (high and intermediate grade) were treated with a new protocol: continuous cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP). They were evaluated for long-term survival and pretreatment characteristics predictive of response and survival. Continuous CHOP protocol consists of initial 8 weeks of intensive chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisolone, followed by local/cranial radiotherapy and maintenance therapy. Complete remission (CR) was achieved in 84 of 108 (78%) patients; seven (6%) had a moderate response and 17 (16%) had a poor response. A statistically significant difference in CR rate was found only in patients with different stages. Seventeen of 84 (20%) complete responders have had a relapse of the disease. The median survival has not been reached. Results show an actuarial disease-free survival (DFS) of 77% for the 84 patients who had a complete response. The overall survival for all patients was 53% at 5 years of follow-up. The difference in DFS at the end of 5 years between different stages, main histologic subgroups, and age groups was not statistically significant. The toxicity observed was acceptable. Thus continuous CHOP appears to be an effective protocol for the treatment of intermediate-grade and high-grade lymphomas.
