title: Preliminary report on the clinical use of human leukocyte interferon in neuroblastoma.
abstract: The effectiveness of human leukocyte interferon (IF) injections on a female patient, 21 years old, with stage IV neuroblastoma was observed. IF (30 X 10(4) units) injected every second day intratumorally or around the tumor tissue rapidly reduced the tumor size. However, systemic administration of 300 x 10(4) units of IF by im injection showed no beneficial effects. Our results suggest that a high IF level in tumor tissue may be necessary to bring about tumor reduction.
