Case Reports Randomized Controlled Trial Clinical TrialPulmonary toxicity of carmustine in patients treated for malignant glioma.
Carmustine (BCNU) was employed as the only chemotherapeutic agent in a Radiation Therapy Oncology Group multimodality study comparing misonidazole-radiosensitized radiation therapy to conventional radiation therapy in 318 patients with malignant glioma. In 289 patients evaluable for BCNU pulmonary toxicity, there were no clinical manifestations of toxicity in patients receiving less than 902-mg/m2 total BCNU dose. ⋯ Results of a multivariate regression analysis of risk factors, which corrects for survival time bias, suggested increased risk of pulmonary toxicity when total dose exceeds 1400 mg/m2. The risk of pulmonary toxicity was not increased by the administration of misonidazole and does not appear to be related to age.

Effects of Mega-COMLA (cyclophosphamide, cytarabine, vincristine, and methotrexate followed by leucovorin and prednisone) plus CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) in the treatment of lymphoid neoplasms with very poor prognosis.
Treatment results remain very poor for some clinical and histopathologic subsets of patients with aggressive non-Hodgkin's lymphoma. We treated 21 such patients with a high-dose combination chemotherapy regimen [Mega-COMLA (cyclophosphamide, cytarabine, vincristine, and methotrexate followed by leucovorin and prednisone) + CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone)] in an attempt to improve disease-free survival. Neoplasms were classified using the Lukes-Collins system. ⋯ High-dose induction therapy with this regimen resulted in a high complete remission rate with manageable toxicity. Survival results are encouraging when compared retrospectively to our patients with similar poor-prognosis histologies treated with standard combination chemotherapy. However, the value of this intensive therapy, relative to newer ("third-generation") regimens, can only be established by prospective randomized studies.

Modified cyclophosphamide, vincristine, methotrexate, leucovorin, and cytarabine (COMLA) in intermediate- and high-grade lymphoma: an effective short-course regimen.
Twenty-one patients with intermediate- and high-grade lymphomas were treated with modified cyclophosphamide, vincristine, methotrexate, leucovorin, and cytarabine (COMLA). This regimen utilizes the drugs used in COMLA in similar doses, but cyclophosphamide is given twice as frequently, cytarabine is given by continuous infusion, and the total duration of therapy is reduced to 16 weeks. ⋯ This regimen was myelotoxic, but there were no toxic deaths. Modified COMLA is a relatively nontoxic regimen producing excellent results in intermediate-grade lymphomas.
