A lower Hb threshold of 8 g per dL does not adversely affect patient outcome. Moreover, RBC resources can be saved without increased risk to the patient.
Based on encouraging results of two previous ifosfamide-VP-16 salvage combinations, methyl-gag was added to ifosfamide, methotrexate, and etoposide (VP-16). This combination is called MIME. A total of 208 patients with recurrent lymphoma were treated with this regimen. Response rates were 24% for complete remission and 36% for partial remission. The MIME regimen was more effective in patients who were treated after being off front-line therapy for longer than 6 months. However, responses were also seen in patients with disease clearly resistant to front-line therapy, suggesting that MIME was at least partially non-cross-resistant with front-line doxorubicin-containing regimens. The 15-month median relapse-free survival of complete responders and the 9-month overall median survival time for all patients treated were both similar to results from previous ifosfamide-VP-16 combination use. This regimen has been effective in the treatment of patients with recurrent or refractory lymphoma, but cannot be considered curative in the majority of cases.
The sperm production of 25 patients with Hodgkin's disease treated with mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) chemotherapy was studied retrospectively. All but two patients also received radiotherapy treatment to pelvic and/or non-pelvic fields. Sperm counts were obtained from patients treated either with three or fewer (MOPP-2 group) or with five or more (MOPP-6 group) chemotherapy cycles. Recovery of spermatogenesis following treatment-induced azoospermia was significantly higher among the MOPP-2 patients (Mann-Whitney rank sum test, p = 0.001). Patients in this group who did not receive pelvic irradiation appeared to have greater recovery rates (p = 0.06). The results suggest that three cycles of MOPP chemotherapy represent a maximum exposure compatible with the recovery of spermatogenesis.
We describe the histologic and clinical features of non-Hodgkin's lymphoma diagnosed between January 1980 and December 1983 in 90 homosexual men from San Francisco, Los Angeles, Houston, and New York. The median age was 37 years, with an age distribution identical to that for cases of AIDS reported to the Centers for Disease Control. Sixty-two per cent of the patients had high-grade (aggressive) subtypes of lymphoma, 29 per cent had subtypes of intermediate grade, and 7 per cent had low-grade subtypes. Histologic subtypes and malignant cell phenotypes were consistent with a B-cell origin. All but two men had extranodal lymphoma: central-nervous-system, bone-marrow, bowel, and mucocutaneous sites were most commonly involved. Thirty-five of 66 evaluable men (53 per cent) had complete responses to combination chemotherapy or radiotherapy or both, and thus far, 19 (54 per cent) of them have had a relapse. Mortality and morbidity were closely related to prodromal manifestations; death or illness have occurred in 19 (91 per cent) of the 21 men who presented with AIDS, in 26 (79 per cent) of the 33 who presented with generalized lymphadenopathy, and in 5 (42 per cent) of the 12 who had no prodromal manifestations. Mortality rates analyzed according to histologic grade were higher than currently reported rates in other patient populations. Kaposi's sarcoma or severe opportunistic infections characteristic of AIDS developed in 14 of 33 men (42 per cent) who presented with generalized lymphadenopathy and in 3 of 12 (33 per cent) without prodromal manifestations. We conclude that non-Hodgkin's lymphoma in members of an AIDS risk group is a serious manifestation of AIDS and the AIDS-related complex.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
