Abstract
PURPOSE: To compare a short intensified regimen followed by sequential consolidation therapy (doxorubicin, cyclophosphamide, vindesine, bleomycin, and prednisone [ACVBP]) to the standard regimen of methotrexate, bleomycin, cyclophosphamide, and etoposide (m-BACOD) in patients with low-risk aggressive lymphoma. PATIENTS AND METHODS: A total of 752 patients with intermediate- or high-grade lymphoma and no adverse prognostic factors (Eastern Cooperative Oncology Group performance status of 2 to 4, ≥ two extranodal sites of disease, tumor burden ≥ 10 cm in largest dimension, bone marrow or CNS involvement, Burkitt’s or lymphoblastic subtypes) were registered. Of 673 eligible patients, 332 received ACVBP and 341 received m-BACOD. RESULTS: The complete remission rate was identical (86%) in the two groups. With a median follow-up duration of 7 years, the 5-year failure-free survival (FFS) rate was 65% in the ACVBP group and 61% in the m-BACOD group (P = .16). The 5-year overall survival rate was 75% in the ACVBP group and 73% in the m-BACOD group (P = .47). ACVBP was responsible for more severe and life-threatening infections (P < .01), but m-BACOD caused more pulmonary toxicity (P < .001). The number of treatment-related deaths did not differ between the two regimens. A multivariate analysis indicated that ACVBP was associated with a longer FFS in patients with two or three risk factors of the International Prognostic Index. CONCLUSION: In this population of patients with low-risk aggressive lymphoma, toxicities of the regimens are different, but the rates of response and survival are identical. The survival advantage of ACVBP over standard regimen in patients with advanced disease is suggested by this analysis but remains to be assessed in prospective studies specifically designed for this purpose.
