Most studies have examined <jats:italic>BRCA2<\/jats:italic> alone or an aggregate of <jats:italic>BRCA1\/2<\/jats:italic> and <jats:italic>ATM<\/jats:italic>. Emerging data suggest that <jats:italic>ATM<\/jats:italic> mutations may have distinct biology and warrant individual evaluation. The objective of this study is to determine whether response to prostate cancer systemic therapies differs between men with germline mutations in <jats:italic>ATM<\/jats:italic> (g<jats:italic>ATM)<\/jats:italic> and <jats:italic>BRCA2<\/jats:italic> (g<jats:italic>BRCA2)<\/jats:italic>.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This is an international multicenter retrospective matched cohort study of men with prostate cancer harboring g<jats:italic>ATM<\/jats:italic> or g<jats:italic>BRCA2<\/jats:italic>.

Patients with g<jats:italic>ATM<\/jats:italic> and g<jats:italic>BRCA2<\/jats:italic> had similar age, Gleason grade, and PSA at diagnosis. We did not observe differences in PSA<jats:sub>50<\/jats:sub> responses to abiraterone, enzalutamide, or docetaxel in metastatic castration resistant prostate cancer between the two groups; however, 0\/7 with g<jats:italic>ATM<\/jats:italic> and 12\/14 with g<jats:italic>BRCA2<\/jats:italic> achieved PSA<jats:sub>50<\/jats:sub> response to PARPi (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001).
