Genetic instability is one part of the oncogenic process. Gene mutations involved in DNA repair mechanisms can promote this genetic instability and participate in oncogenesis and metastatic progression.

Mutations in the BRCA1 and BRCA2 genes are associated with increased risk of breast, ovarian, and several other cancers. The purpose of the present study was to evaluate the incidence of cancer in first- and second-degree relatives of BRCA mutation carriers compared with the general population.

Advances in DNA sequencing technology have created a wealth of information regarding the genomic landscape of prostate cancer. It had been thought that BRCA1 and BRCA2 mutations were associated with only a small fraction of prostate cancer cases.

For more precise, personalized care in prostate cancer (PC), a new classification based on molecular features relevant for prognostication and treatment stratification is needed. Genomic aberrations in the DNA damage repair pathway are common in PC, particularly in late-stage disease, and may be relevant for treatment stratification.

To determine the relevance of intraductal carcinoma of the prostate (IDC-P) in advanced prostate cancer, we first examined whether IDC-P was originally present in patients who later developed advanced prostate cancer and then used patient-derived xenografts (PDXs) to investigate the response of IDC-P to androgen deprivation therapy (ADT).

Prostate cancer (PCa) shows a broad spectrum of biological and clinical behavior, which represents the epiphenomenon of an extreme genetic heterogeneity. Recent genomic profiling studies have deeply improved the knowledge of the genomic landscape of localized and metastatic PCa.

One of the most significant risk factors for prostate cancer (PC) is a family history of the disease, with germ-line mutations in the breast cancer predisposition gene (BRCA) 2 conferring the highest risk.

Men who inherit pathogenic germline mutations in BRCA2 and BRCA1 are at increased risk of developing aggressive prostate cancer, and those with germline mutations in other DNA repair genes such as ATM, CHEK2, and MSH2/MSH6 may also have increased risks.

Prostate cancer (PCa) is a disease of mutated and misregulated genes. However, primary prostate tumors have relatively few mutations, and only three genes ( ERG, PTEN, and SPOP) are recurrently mutated in more than 10% of primary tumors.
