Purpose: During the last few years, the application of CD30 monoclonal antibodies has led to the identification of a new lymphoma entity, termed anaplastic large cell lymphoma (ALCL). This tumor includes four distinct histologic subtypes, among which the Hodgkin's-like/Hodgkin's-related one (ALCL-HL) shares morphologic and phenotypic features with Hodgkin's disease (HD). Patients and Methods: From September 1988 to October 1993, 90 ALCL patients were treated with third-generation chemotherapy regimens (either vincristine, cyclophosphamide, fluorouracil, cytambine, doxorubicin, methotrexate with leucovorin, and prednisone [F-MA-CHOP] or methotrexate with leucovorin, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin [MACOP-B]) during the course of an Italian multicentric randomized trial on high-grade non-Hodgkin's lymphomas (HG-NHL). In particular, 47 patients had ALCL of the common type (ALCL-CT) and 43 ALCL-HL. Null phenotype was the most common (39.8%), while T-cell, B-cell, and hybrid forms accounted for 35.5%, 22.2%, and 2.5%, respectively. Results: Complete remission (CR) was achieved in 66 of 90 (73.5%) patients (33 of 47 [70%] with ALCL-CT and 33 of 43 [77%] with ALCL-HL). The majority of the patients in CR (56.5%) were alive and well at a median follow-up time of 38 months; no significant differences were observed between the two histologic groups, with the rate of complete responders being 49% and 65% in ALCL-CT and ALCL-HL, respectively. The probability of relapse-free survival (RFS), projected at 63 months, was 67% for ALCL-CT and 82% for ALCL-HL. The risk of lower CR and RFS rates was associated with the presence of bulky disease, advanced stage, and B symptoms. Conclusion: The data of the present study confirm that ALCL responds to third-generation chemotherapy regimens similarly to other aggressive malignant lymphomas in terms of both CR and RFS rates.

Abstract
Purpose: During the last few years, the application of CD30 monoclonal antibodies has led to the identification of a new lymphoma entity, termed anaplastic large cell lymphoma (ALCL). This tumor includes four distinct histologic subtypes, among which the Hodgkin's-like/Hodgkin's-related one (ALCL-HL) shares morphologic and phenotypic features with Hodgkin's disease (HD). Patients and Methods: From September 1988 to October 1993, 90 ALCL patients were treated with third-generation chemotherapy regimens (either vincristine, cyclophosphamide, fluorouracil, cytambine, doxorubicin, methotrexate with leucovorin, and prednisone [F-MA-CHOP] or methotrexate with leucovorin, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin [MACOP-B]) during the course of an Italian multicentric randomized trial on high-grade non-Hodgkin's lymphomas (HG-NHL).
