Among the DDR genes, BRCA2 is the most commonly altered (~ 13%) in advanced therapy-resistant PCa. Patients with BRCA2-altered PCas are exquisitely sensitive to poly (ADP-ribose) polymerase (PARP) inhibitors (PARPis).

Androgen receptor pathway inhibitors, taxane cytotoxic therapy, poly(ADP-ribose) polymerase inhibitors, and radionuclide theranostics against prostate-specific membrane antigen have collectively contributed to incremental improvements in both quality and longevity of life for patients with metastatic castration-resistant prostate cancer (mCRPC). Despite these successes, few studies inform on optimal therapy selection and sequencing across this crowded treatment landscape. Genomic analysis of both tissue and liquid biopsy specimens shows promise in bridging this practice gap, with alterations in several key prostate cancer driver genes demonstrating clear associations with clinical outcomes, as well as informing use of novel precision medicine targeted therapies. In this review, we evaluate the current evidence of genomic alterations in various oncogenic signaling pathways as clinical biomarkers in mCRPC, focusing on correlative studies that analyzed outcomes based on findings in plasma cell-free DNA. We highlight the pitfalls of interpreting genomic findings in samples with substandard tumor content, and suggest pathologic and disease factors to consider when embarking upon tumor genotyping to guide treatment decisions in metastatic prostate cancer. As access to life-prolonging therapies improves, and barriers to cost-effective genotyping and reliable data interpretation are overcome, we anticipate that predictive and prognostic biomarkers that inform on disease biology, drug sensitivity, and therapy resistance will inevitably be integrated into the routine care of patients with metastatic prostate cancer.</p>","PeriodicalId":35617,"journal":{"name":"Critical Reviews in Oncogenesis","volume":" ","pages":"61-80"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40417036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current screening options have limitations and have been shown to result in over-treatment of clinically insignificant disease.

Circulating cell-free DNA (ccfDNA) has gained interest as a potential minimally invasive biomarker, detectable in many bodily fluids (such as blood, urine, and cerebral spinal fluid) and reflecting the mutational landscape in tumors. More recently, the size distribution of ccfDNA fragments has also gained interest as a specific biomarker, where differences in size distribution have been observed between healthy volunteers and cancer patients, resulting in the new field of fragmentomics. Analysis of ccfDNA sizes provides avenues for alternative analytical technologies but commercial options are currently limited. Most focus on mutation detection and are subject to several biases that may affect size distribution.
