Background: According to recent reports, ~1 in 4 patients with metastatic prostate cancer may harbor alterations in DNA damage repair (DDR) genes. Clinical trial data demonstrates that prostate cancer patients with DDR mutations may respond to poly-ADP ribose polymerase (PARP) inhibitors. Less is known about the mutational profile in minority patients with prostate cancer. We sought to determine the genomic profile of prostate cancer in an ethnically diverse patient population at a single center. Methods: We performed a retrospective review of men with prostate cancer at the Montefiore-Einstein Cancer Center who had next generation sequencing (NGS) with FoundationOne solid tumor testing between 2/2016 - 8/2019. Individual chart review was used to obtain clinical and demographic data including self-reported race/ethnicity. Results: NGS was attempted on archival tissue from 95 patients and results were obtained for 85. Among patients with results, the self-reported race/ethnicity was: Hispanic (H) 37.6%, Non-Hispanic Black (NHB) 52.9%, Non-Hispanic White (NHW) 4.7%, and Other (O) 4.7%. At the time of tissue sampling, 61 patients had metastatic disease and 10 were castration-resistant. 63 samples were from the prostate, 7 from bone, 7 from lymph node, 3 from liver and 5 from other soft tissue sites. The most commonly altered genes included: TP53 (26%), TMPRSS2-ERG fusion (23%), and PTEN (17%). Alterations in the androgen receptor were identified in 5 samples (all with CRPC). 32.8% had alterations in DDR genes including BRCA2 9 (10.6%), ATM 7 (8.2%), ATR 4 (4.7%), BRIP1 2 (2.3%), CDK12 3 (3.5%), FANCA 2 (2.3%), and PALB2 1 (1.2%). Alterations in mismatch repair genes (MSH2, MLH1, MSH6, PMS2) were present in 4 (4.7%) patients (3 of these were MSI-H). In samples where tumor mutational burden (TMB) was reported, 4 (4.7%) were TMB-high (3 MSI-H and 1 with POLE mutation). Conclusions: DDR gene mutations are common in this primarily minority population. As DDR mutations become more common in the CRPC setting, our data may underestimate the frequency of DDR mutations as only 10 patients had CRPC at the time of tissue sampling. Minority men, like all men, with prostate cancer should be considered for genomic analysis as results are likely to guide therapeutic decisions.
