BACKGROUND: Regulatory T cells (T(R)) mediate peripheral immunological tolerance and are implicated in tumor progression. Because prostate cancer is being investigated for treatment by immunotherapy, we have assessed tumor T(R) in prostate cancers. METHODS: T(R) cells were identified by FOXP3 in tissue microarrays (TMAs) from 146 radical prostatectomies and correlated with clinicopathological tumor parameters and prostatic specific antigen rise (PSA). RESULTS: Twenty of 146 tumors contained ...Expand abstract
