Modified MACOP-B chemotherapy for intermediate and high grade non Hodgkins lymphomas.

ABSTRACT

Combination chemotherapy consisting of methotrexate with leucovorin rescue, doxorubicin, cyclophosphamide, vincristine, prednisolone and bleomycin (MACOP-B) has been extensively used for the treatment of Non Hodgkins Lymphoma. However, different results have been reported. The aim of this study was to assess the feasibility of administration of this regimen on an out patient basis and to confirm the efficacy of MACOP-B. 51 patients with intermediate--and high--grade lymphoma were treated with this regimen in a single institute study. Numerous clinical features predictive of response and disease free survival were analysed. The Median age was 48 years (range 14-77). Diffuse large cell lymphoma was seen in 65%, diffuse small cleaved in 10% and diffuse mixed in 15%. Eight patients (15%) had Stage I disease, 18 (35%) Stage II, 12 (23%) Stage III and 13 (25%) Stage IV. Complete remission was achieved in 65% of the patients. With a median follow up of 18 months, 40% of the patients are alive at 40 months. Sixty percent of the complete responders are disease free at 40 months. Response rates did not differ significantly for age, sex, stage, histology, bone marrow involvement and extranodal disease. However patients with absence of B' symptoms, non bulky disease at presentation and diffuse large cell histology had a higher percentage of complete remission. Hematological toxicity occurred in 90% and was grade IV in 14% patients. Three patients died of sepsis. Severe mucositis occurred in 40% of the patients. In conclusion, while it is possible to give aggressive chemotherapy at the out patient basis in India we failed to confirm the high response rates as originally reported.
