RT Journal Article SR Electronic T1 BRCA2 gene mutation and prostate cancer risk JF Saudi Medical Journal JO Saudi Med J FD Prince Sultan Military Medical City SP 9 OP 17 DO 10.15537/smj.2020.1.24759 VO 41 IS 1 A1 Noor N. Junejo A1 Sultan S. AlKhateeb YR 2020 UL http://smj.org.sa/content/41/1/9.abstract AB The second most common type of tumor worldwide is prostate cancer (PCa). Certain genetic factors contribute to a risk of developing PCa of as much as 40%. BRCA1 and BRCA2 mutations have linked with an increased risk for breast, ovarian, and PCa. However, BRCA2 is the most common gene found altered in early-onset of PCa in males younger than 65. BRCA2 mutation has a higher chance of developing an advanced stage of the disease, resulting in short survival time. This review aimed to describe the genetic changes in BRCA2 that contribute to the risk of PCa, to define its role in the early diagnosis in a man with a strong family history, and to outline the purpose of genetic testing and counseling. Also, the review summarizes the impact of BRCA2 gene mutation in localized PCa, and the treatment strategies have used for PCa patients with a BRCA2 modification.
