title: Sites of relapse in patients with neuroblastoma following bone marrow transplantation in relation to preparatory "debulking" treatments.
abstract: Forty-one patients with high-risk neuroblastoma were treated between September 1977 and December 1987 at the Children's Hospital of Philadelphia with supralethal chemotherapy and total-body irradiation rescued by bone marrow transplantation. Twenty-six patients were treated following relapse and 15 were newly diagnosed. At the time of evaluation, January 1991, 11 of 41 patients (26.8%) remained in complete remission. Actuarial survival rates of patients transplanted following relapse were 0.35 and 0.31 at 2 and 5 years, respectively, and actuarial disease-free survival rates were 0.38 at 12 months and 0.27 at 24 months. The 2- and 5-year actuarial survival values for the patients with newly diagnosed disease were 0.53 and 0.25, respectively, and the 12- and 24-month disease-free survival rates were 0.47 and 0.27, respectively. There was no significant difference in survival between these groups. Twenty-nine of the 41 patients reviewed were available for analysis of the effect of local treatment. Thirteen had a combination of surgery and radiation (RT), 2 had surgery alone, 9 had RT alone, and in 5 patients no local treatment was given. The local relapse rate was 17%; it was 15% following surgery plus RT and 22% following RT alone. The failure rate combining local and distant relapse is 62% for surgery plus RT and 44% for RT alone. Although a local relapse rate of 17% is imperfect, it is a relatively small contribution to the overall relapse of 62%.
