BACKGROUND
Pathogenic variants (PVs) of BRCA1 and BRCA2 predispose individuals to a higher risk of breast and ovarian cancer; however, the precise risks posed by other cancer susceptibility genes remain unclear, particularly in Asian populations.
METHODS
We executed a case-control study of 11 and 26 genes associated with breast and ovarian cancer susceptibility, respectively, in 7220 women with breast cancer, 2464 women with ovarian cancer, and 4032 controls from a multicentre, hospital-based registry in Japan. Furthermore, we conducted a meta-analysis of 23,193 patients with breast and/or ovarian cancer and 31,190 controls from six other hospital-based studies.
FINDINGS
Overall, 395 (5.5%) patients with breast cancer and 331 (13.4%) patients with ovarian cancer harboured PVs. Meta-analyses revealed that PVs of BRCA1, BRCA2, CHEK2, PALB2, and TP53 were associated significantly with breast cancer risk (P < 0.001), while PVs of ATM, BRCA1, BRCA2, MSH6, and RAD51D were associated significantly with ovarian cancer risk (P < 0.001). PVs in the BRCA1 DNA-binding domain were associated with a younger age at diagnosis after adjusting for cancer type and family history (β = -3.79, 95% CI = -7.16 to -0.41; P = 0.028).
INTERPRETATION
These results provide information about genes associated with breast and ovarian cancer risk in Asian women, as well as guidance for management of PV carriers.
FUNDING
The study was funded by AMED (JP15ck010609, 19cm0106605h0003, 23ama221520h0001, and JP19kk0305010), by a Health Labour Sciences Research Grant (202108001B), by JSPS KAKENHI (JP18K16292, 20H03668, 23H02955, 17H06162, 20H03695, and 16H06277), and by a Grant-in-Aid for the Genome Research Project from Yamanashi Prefecture.
背景
BRCA1和BRCA2的致病性变异（PVs）使个体患乳腺癌和卵巢癌的风险更高；然而，其他癌症易感基因所带来的精确风险仍不明确，尤其是在亚洲人群中。
方法
我们对来自日本一个多中心、基于医院的登记处的7220名乳腺癌女性、2464名卵巢癌女性和4032名对照者进行了一项病例对照研究，分别涉及11个和26个与乳腺癌和卵巢癌易感性相关的基因。此外，我们对来自其他六项基于医院的研究的23193例乳腺癌和/或卵巢癌患者及31190名对照者进行了荟萃分析。
研究结果
总体而言，395名（5.5%）乳腺癌患者和331名（13.4%）卵巢癌患者携带PVs。荟萃分析显示，BRCA1、BRCA2、CHEK2、PALB2和TP53的PVs与乳腺癌风险显著相关（P<0.001），而ATM、BRCA1、BRCA2、MSH6和RAD51D的PVs与卵巢癌风险显著相关（P<0.001）。在调整癌症类型和家族史后，BRCA1 DNA结合域中的PVs与诊断时较年轻的年龄相关（β=-3.79，95%CI=-7.16至-0.41；P=0.028）。
解读
这些结果提供了有关亚洲女性乳腺癌和卵巢癌风险相关基因的信息，以及对PV携带者管理的指导。
