Progress of hereditary breast cancer with breast cancer susceptibility gene 1/2 mutations / 肿瘤研究与临床

ABSTRACT

Hereditary breast cancer refers to malignant tumors caused by pathogenic germline mutations of breast cancer susceptibility genes (BRCA). At present, it is believed that BRCA1/2 genes are most closely related to the development of hereditary breast cancer. Mutation will lead to loss of normal function, instability of genome, and then lead to tumorigenesis. Especially for those with germline mutations, not only the risk of breast cancer will be greatly increased, but also the probability of ovarian cancer and other cancers will be increased. With the emergence and clinical application of poly (adenosine diphosphate-ribose) polymerase (PARP) inhibitors, BRCA1/2 genes have been regarded as new targets for the treatment of breast cancer. This article reviews the latest research of breast cancer with BRCA1/2 gene mutations.
