中文摘要
项目摘要/摘要:据估计,每190名妇女中就有1人携带BRCA1/2致病变异,
这与70岁时患乳腺癌的风险为46%-57%,患卵巢癌的风险为20%-40%有关。
携带者分别占乳腺癌和卵巢癌病例的10%和15%,高达20%的高危患者。
恶性浆液性卵巢癌是最具侵袭性的亚型。尽管有建议说所有卵巢
癌症患者应该接受遗传咨询和检测,而不考虑家族史和发病年龄。
最近的全国性研究表明,只有10%的病例接受了基因检测。这表示未命中
向这些妇女及其高危家庭成员通报她们未来的癌症风险的机会。这个
拟议的研究通过应用追溯测试方法来解决这一护理缺口,以追溯确定
曾被诊断患有卵巢癌的女性。然后这些妇女将被提供遗传咨询,
测试和癌症风险评估。这项研究将利用肿瘤登记来识别以前的病例

英文摘要
PROJECT SUMMARY/ABSTRACT: An estimated 1 in 190 women carry a pathogenic variant in BRCA1/2,
which is associated with an 46-57% risk of breast cancer and 20-40% risk of ovarian cancer by age 70.
Carriers account for 10% and 15% of breast and ovarian cancer cases, respectively, and up to 20% of high-
grade serous ovarian cancer cases, the most aggressive subtype. Despite recommendations that all ovarian
cancer cases should receive genetic counseling and testing, irrespective of family history and age at onset, a
recent national study indicated that only 10% of cases underwent genetic testing. This represents a missed
opportunity to inform these women and their at-risk family members about their future cancer risk. The
proposed study addresses this care gap by applying a traceback testing approach to retrospectively identify
women who have a prior diagnosis of ovarian cancer. These women will then be offered genetic counseling,
testing, and cancer risk assessment. This study will leverage tumor registries to identify prior cases of
ovarian cancer diagnosed within the past 10 years at two managed care healthcare systems (Kaiser
Permanente Northwest and Kaiser Permanente Colorado). The use of archived pathology samples for
germline genetic testing will allow family members of both living and deceased women to receive familial
genetic cancer risk information. We will assess: 1) the feasibility of and barriers associated with using tumor
registries and archived pathology samples for a traceback testing approach; 2) explore the ethical, privacy,
and policy implications associated with genetic testing in deceased patients to inform familial risk; 3)
characterize barriers to receiving genetic counseling at the time of diagnosis, including barriers to referral,
care access, and patient follow-up to. We have assembled a multidisciplinary team with expertise in
bioethics, genetic epidemiology, genomic medicine, biostatistics, health communication, and medical
genetics. We will engage patients, family members, providers, and health system administrators to guide
study design and characterize barriers to genetic testing in ovarian cancer. Our unique integrated health
information systems, tumor registries, and archived pathology specimens make us ideally suited to
investigate the feasibility of traceback testing. Generating evidence on the feasibility of traceback testing
using tumor registries and archived pathology samples is critically important to the guide future
implementation of such programs beyond ovarian cancer.
