PURPOSE
There are deficient data on prevalence of germline mutations in breast cancer susceptibility genes 1 and 2 (/) in Indian patients with ovarian cancer who are not selected by clinical features.
METHODS
This prospective, cross-sectional, noninterventional study in nine Indian centers included patients with newly diagnosed or relapsed epithelial ovarian, primary peritoneal, or fallopian tube cancer. The primary objective was to assess the prevalence of / mutations, and the secondary objective was to correlate / status with clinicopathologic characteristics. Mutation testing was performed by a standard next-generation sequencing assay.
RESULTS
Between March 2018 and December 2018, 239 patients with a median age of 53.0 (range, 23.0-86.0 years) years were included, of whom 203 (84.9%) had newly diagnosed disease, 36 (15.1%) had family history of ovarian or breast cancer, and 159 (66.5%) had serous subtype of epithelial ovarian cancer. Germline pathogenic or likely pathogenic mutations in and were detected in 37 (15.5%; 95% CI, 11.1 to 20.7) and 14 (5.9%; 95% CI, 3.2 to 9.6) patients, respectively, whereas variants of uncertain significance in these genes were seen in four (1.7%; 95% CI, 0.5 to 4.2) and six (2.5%; 95% CI, 0.9 to 5.4) patients, respectively. The prevalence of pathogenic or likely pathogenic mutations in patients with serous versus nonserous tumors, with versus without relevant family history, and ≤ 50 years versus > 50 years, were 40 of 159 (25.2%; 95% CI, 18.6 to 32.6) versus 11 of 80 (13.8%; 95% CI, 7.1 to 23.3; = .0636), 20 of 36 (55.6%; 95% CI, 38.1 to 72.1) versus 41 of 203 (20.2%; 95% CI, 14.9 to 26.4; < .0001), and 20 of 90 (22.2%; 95% CI, 14.1 to 32.2) versus 31 of 149 (20.8%; 95% CI, 14.6 to 28.2; = .7956), respectively.
CONCLUSION
There is a high prevalence of pathogenic or likely pathogenic germline mutations in Indian patients with ovarian cancer.
目的
在未通过临床特征选择的患有卵巢癌的印度患者中，关于乳腺癌易感基因 1 和 2（/）种系突变的流行率数据较少。
方法
本研究为在印度 9 个中心进行的前瞻性、横断面、非干预性研究，纳入了新诊断或复发的上皮性卵巢癌、原发性腹膜癌或输卵管癌患者。主要目的是评估/突变的流行率，次要目的是分析/状态与临床病理特征的相关性。突变检测采用标准的下一代测序分析。
结果
2018 年 3 月至 2018 年 12 月期间，共纳入 239 例中位年龄为 53.0（范围：23.0-86.0 岁）岁的患者，其中 203 例（84.9%）为新诊断疾病，36 例（15.1%）有卵巢癌或乳腺癌家族史，159 例（66.5%）为浆液性上皮性卵巢癌。在 37 例（15.5%；95%CI：11.1-20.7）和 14 例（5.9%；95%CI：3.2-9.6）患者中分别检测到/基因的致病性或可能致病性突变，而在这两个基因中发现了 4 例（1.7%；95%CI：0.5-4.2）和 6 例（2.5%；95%CI：0.9-5.4）患者的意义不确定的变异。在浆液性肿瘤与非浆液性肿瘤、有或无相关家族史、≤50 岁与>50 岁的患者中，致病性或可能致病性/突变的流行率分别为 159 例中的 40 例（25.2%；95%CI：18.6-32.6）与 80 例中的 11 例（13.8%；95%CI：7.1-23.3；=0.0636）、36 例中的 20 例（55.6%；95%CI：38.1-72.1）与 203 例中的 41 例（20.2%；95%CI：14.9-26.4；<0.0001）和 90 例中的 20 例（22.2%；95%CI：14.1-32.2）与 149 例中的 31 例（20.8%；95%CI：14.6-28.2；=0.7956）。
结论
印度卵巢癌患者中存在高比例的致病性或可能致病性/种系突变。
