Effects of transfer factor in patients with advanced cancer
Abstract:
Eighteen patients with advanced cancer were given subcutaneous injections of pooled dialyzable transfer factor (TFd) from normal donors for periods of from 9 days to 6.5 months. Minor tumor regression was observed in only two patients, an effect of no therapeutic significance. However, treatment with TFd was associated with at least a temporary increase in delayed hypersensitivity reactions in 12 of 17 patients tested, including four patients who became responsive to 2,4-dinitrochlorobenzene. In general, in vitro tests of immune function were not changed after treatment with TFd except for levels of C1q, and/or C3, which were increased in 6 of 10 patients tested. We conclude that TFd may augment delayed hypersensitivity in patients with advanced cancer, and that its effects are, at least in part, immunologically nonsepcific.
