Prostate cancer patients receiving ADT showed significantly reduced pulmonary TMPRSS2 expression compared to non-ADT patients (mean histoscores: 152.7 vs. 225.0, p = 0.037) and age-matched women controls (mean histoscores: 152.7 vs. 238.0, p = 0.024). This evidence concerns the gene TMPRSS2 and Familial prostate cancer.
