[EX Q]: Question: Does cryosurgical ablation of the normal ventral prostate plus adjuvant protect Copenhagen rats from Dunning prostatic adenocarcinoma challenge?
Answer: Cryosurgical ablation of the normal rat ventral prostate and intraprostatic CFA does not protect against and can enhance the tumorigenicity of MatLyLu prostatic cancer cells at distant sites. This could be occurring through specific immunologic effects or non-specific mechanisms induced by cryosurgery and CFA.
