Intratumoral induction of tumour necrosis factor (TNF) by administration of Bordetella pertussis vaccine (BPV) as compared with that by the agent OK-432 was investigated in mice. Two hours after such administration tumour tissues tested were resected from the mice, homogenised, and the TNF activities in the homogenate were assayed using a L-929 fibroblast assay. Intravenous injection of BPV into mice bearing the MM46 carcinoma resulted in a greater concentration of TNF in the tumour homogenate than in the serum. With OK-432, however, there was a greater concentration of TNF in the serum than in the tumour homogenates. A high level of intratumoral TNF induction by BPV was also observed in mice bearing Meth A fibrosarcoma or Lewis lung carcinoma. The therapeutic effect against the Meth A fibrosarcoma was in parallel with the intratumoral TNF activity. Intratumoral TNF activity is therefore believed to be a good index of therapeutic effect.
