1  背景与概念        卵巢癌新发病例逐年增加，尽管靶向维持治疗取得较大进展，但卵巢癌的病死率仍然居高不下。2020年全球卵巢癌新发病例约为313 959例，死亡207 252例；我国2020年卵巢癌新发病例55 342例，死亡病例达到37 519例［1］。上皮性卵巢癌（epithelial ovarian carcinoma，EOC）占所有卵巢恶性肿瘤的 85％以上。按组织形态学特征分类，上皮性卵巢癌的4种最常见亚型是浆液性癌（80％～85％），子宫内膜样癌（10％），透明细胞癌（5％）和黏液性癌（3％）［2-3］。浏览更多请关注本刊微信公众号及当期杂志。

After risk-reducing salpingo-oophorectomy (RRSO), BRCA1/ 2 pathogenic variant (PV) carriers have a residual risk to develop peritoneal carcinomatosis (PC). The etiology of PC is not yet clarified, but may be related to serous tubal intraepithelial carcinoma (STIC), the postulated origin for high-grade serous cancer. In this systematic review and individual patient data meta-analysis, we investigate the risk of PC in women with and without STIC at RRSO.

Based on the current understanding of a preventive effect of bilateral salpingectomy on ovarian/fallopian/peritoneal cancers, the Korean Society of Obstetrics and Gynecology, Korean Society of Gynecologic Endocrinology, Korean Society of Gynecologic Oncology, Korean Society of Maternal Fetal Medicine, and Korean Society for Reproductive Medicine support the following recommendations: • Women scheduled for hysterectomy for benign gynecologic disease should be informed that bilateral salpingectomy reduces the risk of ovarian/fallopian/peritoneal cancer, and they should be counseled regarding this procedure at the time of hysterectomy. • Although salpingectomy is generally considered as a safe procedure in terms of preserving ovarian reserve, there is a lack of evidences representing its long-term outcomes. Therefore, patients should be informed about the minimal potential of this procedure for decreasing ovarian reserve. • Prophylactic salpingectomy during vaginal hysterectomy is favorable in terms of prevention of ovarian/fallopian/peritoneal cancer, although operation-related complications minimally increase with this procedure, compared to the complications associated with vaginal hysterectomy alone. Conversion to open or laparoscopic approach from vaginal approach to perform prophylactic salpingectomy is not recommended. • Women who desire permanent sterilization at the time of cesarean delivery could be counseled for prophylactic salpingectomy before surgery on an individual basis.

The cumulative lifetime risk of ovarian cancer is 16–68% and 11–30% in female BRCA1 and BRCA2 gene alteration carriers, respectively. Risk-reducing bilateral salpingo-oophorectomy (RRSO) is the only proven way to reduce ovarian cancer mortality. We report a series of patients who underwent risk-reducing surgery at the time of planned obstetric-indicated cesarean delivery.

There remains debate about whether risk-reducing salpingo-oophorectomy (RRSO), which reduces ovarian cancer risk, also reduces breast cancer risk. We examined the association between RRSO and breast cancer risk using a prospective cohort of 17 917 women unaffected with breast cancer at baseline (7.2% known carriers of BRCA1 or BRCA2 mutations). During a median follow-up of 10.7 years, 1046 women were diagnosed with incident breast cancer. Modeling RRSO as a time-varying exposure, there was no association with breast cancer risk overall (hazard ratio [HR] = 1.04, 95% confidence interval [CI] = 0.87 to 1.24) or by tertiles of predicted absolute risk based on family history (HR = 0.68, 95% CI = 0.32 to 1.47, HR = 0.94, 95% CI = 0.70 to 1.26, and HR = 1.10, 95% CI = 0.88 to 1.39, for lowest, middle, and highest tertile of risk, respectively) or for BRCA1 and BRCA2 mutation carriers when examined separately. There was also no association after accounting for hormone therapy use after RRSO. These findings suggest that RRSO should not be considered efficacious for reducing breast cancer risk.© The Author(s) 2018. Published by Oxford University Press.

Most women with a BRCA1/2 pathogenic variant undergo premature menopause with potential short- and long-term morbidity due to the current method of ovarian carcinoma prevention: risk-reducing salpingo-oophorectomy (RRSO). Because the fallopian tubes play a key role in ovarian cancer pathogenesis, salpingectomy with delayed oophorectomy may be a novel risk-reducing strategy with benefits of delaying menopause.To compare menopause-related quality of life after risk-reducing salpingectomy (RRS) with delayed oophorectomy with RRSO in carriers of the BRCA1/2 pathogenic variant.A multicenter nonrandomized controlled preference trial (TUBA study), with patient recruitment between January 16, 2015, and November 7, 2019, and follow-up at 3 and 12 months after surgery was conducted in all Dutch university hospitals and a few large general hospitals. In the Netherlands, RRSO is predominantly performed in these hospitals. Patients at the clinical genetics or gynecology department between the ages of 25 and 40 years (BRCA1) or 25 to 45 years (BRCA2) who were premenopausal, had completed childbearing, and were undergoing no current treatment for cancer were eligible.Risk-reducing salpingo-oophorectomy at currently recommended age or RRS after completed childbearing with delayed oophorectomy. After RRSO was performed, hormone replacement therapy was recommended for women without contraindications.Menopause-related quality of life as assessed by the Greene Climacteric Scale, with a higher scale sum (range, 0-63) representing more climacteric symptoms. Secondary outcomes were health-related quality of life, sexual functioning and distress, cancer worry, decisional regret, and surgical outcomes.A total of 577 women (mean [SD] age, 37.2 [3.5] years) were enrolled: 297 (51.5%) were pathogenic BRCA1 variant carriers and 280 (48.5%) were BRCA2 pathogenic variant carriers. At the time of analysis, 394 patients had undergone RRS and 154 had undergone RRSO. Without hormone replacement therapy, the adjusted mean increase from the baseline score on the Greene Climacteric Scale was 6.7 (95% CI, 5.0-8.4; P < .001) points higher during 1 year after RRSO than after RRS. After RRSO with hormone replacement therapy, the difference was 3.6 points (95% CI, 2.3-4.8; P < .001) compared with RRS.Results of this nonrandomized controlled trial suggest that patients have better menopause-related quality of life after RRS than after RRSO, regardless of hormone replacement therapy. An international follow-up study is currently evaluating the oncologic safety of this therapy.ClinicalTrials.gov Identifier: NCT02321228.
