title: High-dose nitrogen mustard (HN2) with autologous nonfrozen bone marrow transplantation in advanced malignant melanoma. A phase I trial.
abstract: In a Phase I trial patients with advanced malignant melanoma were treated with high-dose nitrogen mustard (HN2) and autologous bone marrow transplantation. Three patients were entered into the protocol. After procurement of 1.1--5.5 x 10(5) committed stem cells (CFU-C) per kg body wt, 33 mg/m2 of HN2 was administered i.v. as a bolus. Forty-eight hours later the noncryopreserved bone marrow was reinfused i.v. Side effects consisted of nausea, vomiting, anorexia, alopecia, phlebitis, hepatotoxicity, and neurotoxicity. Cardiotoxicity and hypocalcemia were encountered as unanticipated side effects not described so far by using lower dosages of HN2. Granulocytopenia of less than 10 x 10(9)/l and thrombocytopenia of less than 50.0 x 10(9)/l lasted for a mean of 10 and 8 days, respectively. Measureable disease present in two of three patients did not respond to the dose of HN2 used in this protocol. This study shows that hematologic recovery was shorter than previously reported in studies using HN2 without autologous bone marrow transplantation. The nonhematologic side effects of this dose of HN2, however, were severe and preclude the use of higher doses.
