Early toxicity of intensified conditioning with etoposide combined with total body irradiation/cyclophosphamide or busulfan/cyclophosphamide in children undergoing autologous or allogeneic bone marrow transplantation.
In recent years, high dose chemotherapy followed by bone marrow rescue has been established as a common treatment of hematologic and solid tumor malignancies. Despite unequivocal success, relapse after transplant remains a serious problem, being the main cause of treatment failure. In an attempt to reduce relapse rates, we intensified the conditioning regimens consisting of busulfan/cyclophosphamide versus fractionated total body irradiation (f-TBI)/ cyclophosphamide by the addition of high dose etoposide. Toxicity profiles of 25 pediatric patients with hematologic malignancies undergoing intensified conditioning did not differ significantly between the two groups, except for a higher incidence of veno-occlusive disease in busulfan-treated patients (3 of 13 patients) compared with the TBI group (0 of 12 patients). We observed no transplant-related mortality in neither group. Regimen-associated morbidity was moderate and reversible in all cases. Five patients died in each treatment arm, due to relapse of the underlying disease. We conclude that both regimens are feasible in marrow transplantation of pediatric patients. Open randomized trials are needed to assess the efficacy of intensified conditioning in terms of disease-free survival.

Neocarzinostatin: report of a phase II clinical trial.
Fifty-three patients received intensive treatment with neocarzinostatin in doses of 3500 units/m2 by iv bolus infusion daily for 5-14 days. The response rate for 22 patients with leukemia was 9%. One complete and one partial remission were observed among nine patients with chronic myelogenous leukemia in blast cell crisis. None of the 31 patients with solid tumors responded to treatment. With this dose schedule, prolonged thrombocytopenia and cumulative bone marrow toxicity limit the intensity and duration of neocarzinostatin therapy. Acute allergic reactions occurred in 28% of the treatment courses, and three patients developed anaphylaxis during the second or third course of therapy.
