Neuroblastoma and transfer factor.

Some authors have demonstrated the cytotoxic capacity of the mother's lymphocytes against the neuroblastoma cells of the son. It is not known if that is the reason for the better prognosis of these tumors in early infancy, and it was decided to treat some similar patients with transfer factor from the mother. The conditions for the patients were: more than 2 years old, poor response to chemotherapy and/or part of the tumor not resected. 3 to 5 doses of transfer factor were administered to 3 patients 2 1/2, 4 and 6 years old. One dose was taken from 400 ml of blood and prepared as described in the literature. The patients remained without metastasis more than 1 year after the treatment.
