Abstract

The French-Italian Cooperative Study Group included patients with poor-prognosis AIDS-related non-Hodgkin's lymphoma (NHL), defined as those with performance status (PS) ≥ 3 and/or opportunistic infections (OI), in a prospective study with a 50% reduced-dose combination chemotherapy regimen: CHVmP-Vincristine-bleo (cyclophosphamide 300 mg/m2 i.v. day 1, doxorubicin 25 mg/m2 i.v. day 1, teniposide 30 mg/m2 i.v. day 1, prednisone 20 mg/m2 per os days 15, vincristine 2 mg i.v. day 15, and bleomycin 10 mg i.v. day 15), given every 21 days for eight cycles, and concomitant zidovudine 500 mg per os per day. The aims of this combined treatment were to reduce bone marrow toxicity and infectious complications related to chemotherapy (with a low-dose chemotherapy regimen), and to control the HIV and related infectious complications (with zidovudine therapy). Thirty-seven patients entered this prospective study. At the time of the NHL diagnosis, 41% of the patients had asymptomatic HIV infection, 27% had ARC and 32% had already had CDC-defined diagnoses of AIDS. The median CD4+ cell count was 35 mm3. Only 29 patients are evaluable for response, since 8 received only one cycle of chemotherapy. Fifteen of 29 (52%) patients obtained objective responses, with only 4 (14%) achieving complete remissions (CR) of 1, 4, 14 and 29+ months. Three (16%) CRs were achieved in 19 evaluable patients included in the study because of poor PS, and only one CR was observed in 10 evaluable patients with histories of OI, either alone or with poor PS. The most common side effect was bone marrow toxicity with 2 related toxic deaths. Of the 21 (72%) patients who received concomitant zidovudine treatment, only 12 (57%) were able to receive the drug during chemotherapy. The other 9 patients had to stop the anti-retroviral treatment due to hematological toxicity. Nine (43%) cases of OI were observed among the 21 patients who received zidovudine. Of the 16 patients who did not receive zidovudine, the reason in 13 instances was the presence of granulocytopenia at diagnosis of the NHL, and refusal of the drug in three. Five (31%) cases of OI were observed. In conclusion, this study revealed that patients with poor-prognosis AIDS-related NHL did not benefit from a combined low-dose chemotherapy regimen and concomitant zidovudine treatment. We obtained a lower CR rate than the ones in other published reports using conventional or low-dose chemotherapy. In addition, despite the low-dose chemotherapy regimen employed, we observed significant bone marrow toxicity with 2 deaths, and grades 3 and 4 leukopenia in 27 patients, and grades 3 or 4 thrombocytopenia in 11. Finally, the early application of zidovudine did not prevent a high (43%) incidence of OI during or immediately after treatment.
