Abstract

OBJECTIVES:Estimate the association between non-surgical management (NSM) (e.g. hormonal or radiation therapy) and overall survival among women with stage I endometrioid endometrial cancer (EEC) and identify patient and facility characteristics associated with receipt of NSM. METHODS:Women >45 years of age with clinical stage I EEC were identified in the National Cancer Database from 2004 to 2016. Women treated with NSM were compared with women treated initially with hysterectomy. Patient and facility characteristics associated with NSM were evaluated using logistic regression models. Association with overall survival was examined using log-rank tests, Kaplan-Meier curves, and Cox proportional hazards regression models with and without propensity score matching (PSM). RESULTS:A total of 112,469 women underwent treatment for stage I EEC between 2004 and 2016. 2776 (3%) received NSM, of whom 1987 (71%) received radiation therapy, 688 (25%) received hormonal therapy, and 101 (4%) received both. Older age, black race, higher Charlson-Deyo scores, Medicaid insurance, and low annual facility hysterectomy volume were associated with receiving NSM. The 5-year survival rate was 40% (95%CI: 37%-42%) for women with NSM compared to 89% (95%CI: 88%-89%) for hysterectomy. Women treated with NSM died at a faster rate than those who underwent primary hysterectomy (HR 7.6, 95%CI: 7.2-8.0; p < 0.001). This statistically significant difference in survival persisted in adjusted Cox proportional hazards models and after PSM. CONCLUSIONS:Women treated with NSM had a significantly higher risk of death compared to those undergoing hysterectomy for stage I EEC. Caution should be used when selecting patients for NSM given its worse outcomes.

摘要

目的: 评估非手术治疗 (NSM) (e.g.激素或放射治疗) 和 I 期子宫内膜样内膜癌 (EEC) 妇女的总生存期,并确定与接受 NSM 相关的患者和设施特征。 方法: 在 2004 年至 2016 年国家癌症数据库中确定了临床 I 期 EEC 的> 45 岁女性。将接受 NSM 治疗的妇女与最初接受子宫切除术治疗的妇女进行比较。使用 logistic 回归模型评估与 NSM 相关的患者和设施特征。使用 log-rank 检验、 Kaplan-Meier 曲线和带或不带倾向评分匹配 (PSM) 的 Cox 比例风险回归模型检查与总生存期的相关性。 结果: 2004 年至 112,469 年间,共有 2016 名妇女接受了 I 期 EEC 治疗。2776 例 (3%) 接受 NSM,其中 1987 例 (71%) 接受放射治疗,688 例 (25%) 接受激素治疗,101 例 (4%) 同时接受。年龄较大、黑人种族、较高的 Charlson-Deyo 评分、医疗补助保险和较低的年设施子宫切除术体积与接受 NSM 相关。NSM 妇女的 5 年生存率为 40% (95% CI: 37%-42%),而子宫切除术为 89% (95% CI: 88%-89%)。接受 NSM 治疗的妇女死亡率高于接受子宫切除术的妇女 (HR 7.6,95% CI: 7.2-8.0; P <0.001)。在调整的 Cox 比例风险模型和 PSM 后,这种生存率的统计学显著差异持续存在。 结论: 接受 NSM 治疗的女性死亡风险显著高于接受 I 期 EEC 子宫切除术的女性。鉴于 NSM 预后较差,选择 NSM 患者时应谨慎。

METHODS:STUDY OBJECTIVE:To evaluate the differences in perioperative outcomes and immediate complication rates between laparoscopic myomectomy for submucous myomas and laparoscopic myomectomy for myomas in other locations. DESIGN:Retrospective cohort study. SETTING:University-affiliated hospital in London. PATIENTS:A total of 350 patients with symptomatic uterine myomas underwent laparoscopic myomectomy. Thirty-three of these were performed for submucous myomas (group 1), and 317 were for myomas in other uterine locations (group 2). INTERVENTIONS:Analysis of prospectively collected data on patient demographics, myoma characteristics, perioperative outcomes, and immediate complications. MEASUREMENTS AND MAIN RESULTS:Patient demographics, including age, body mass index, and parity, were similar in the 2 groups. No significant differences in myoma characteristics were seen between groups 1 and 2, including the mean dimension of largest myoma (7.1 vs 7.8 cm, respectively; p = .35), mean number of myomas removed (3.8 vs 4.1; p = .665), and mean mass of myomas removed (142.0 g vs 227.3 g; p = .186). There were also no significant between-group differences in any perioperative outcomes, including mean blood loss (226.8 mL vs 266.4 mL; p = .373), duration of surgery (103 minutes vs 113 minutes; p = .264), and duration of hospital stay (1.4 days vs 1.7 days; p = .057). No complications arose from laparoscopic resection of submucous myomas. CONCLUSION:Laparoscopic myomectomy for submucous myomas has similar perioperative outcomes and immediate complications as laparoscopic myomectomy for other myomas and can be considered for large or type 2 submucous myomas.

METHODS:INTRODUCTION:Laparoscopic myomectomy can be difficult when fibroids are large and numerous. This may result in extensive intraoperative bleeding and the need for a conversion to a laparotomy. Medical pretreatment prior to surgery might reduce these risks by decreasing fibroid size and vascularization of the fibroid. We compared pretreatment with ulipristal acetate (UPA) vs gonadotropin-releasing hormone agonists (GnRHa) prior to laparoscopic myomectomy on several intra- and postoperative outcomes. MATERIAL AND METHODS:We performed a non-inferiority double-blind randomized controlled trial in nine hospitals in the Netherlands. Women were randomized between daily oral UPA for 12 weeks and single placebo injection or single intramuscular injection with leuprolide acetate and daily placebo tablets for 12 weeks. The primary outcome was intraoperative blood loss. Secondary outcomes were reduction of fibroid volume, suturing time, total surgery time and surgical ease. RESULTS:Thirty women received UPA and 25 women leuprolide acetate. Non-inferiority of UPA regarding intraoperative blood loss was not demonstrated. When pretreated with UPA, median intraoperative blood loss was statistically significantly higher (525 mL [348-1025] vs 280 mL[100-500]; P = 0.011) and suturing time of the first fibroid was statistically significantly longer (40 minutes [28-48] vs 22 minutes [14-33]; P = 0.003) compared with GnRHa. Pretreatment with UPA showed smaller reduction in fibroid volume preoperatively compared with GnRHa (-7.2% [-35.5 to 54.1] vs -38.4% [-71.5 to -19.3]; P = 0.001). Laparoscopic myomectomies in women pretreated with UPA were subjectively judged more difficult than in women pretreated with GnRHa. CONCLUSIONS:Non-inferiority of UPA in terms of intraoperative blood loss could not be established, possibly due to the preliminary termination of the study. Pretreatment with GnRHa was more favorable than UPA in terms of fibroid volume reduction, intraoperative blood loss, hemoglobin drop directly postoperatively, suturing time of the first fibroid and several subjective surgical ease parameters.

METHODS:AIMS:Hereditary leiomyomatosis and renal cell cancer (HLRCC) syndrome is caused by germline mutations in the Fumarate hydratase (FH) gene. In young women, the syndrome often presents with symptomatic uterine leiomyomas, leading to myomectomy or hysterectomy. In this study, we aimed to investigate the incidence and mutational profiles of FH-negative leiomyomas from young patients, thus allowing for early identification and triage of syndromic patients for surveillance. METHODS AND RESULTS:We evaluated 153 cases of uterine leiomyomas from women aged up to 30 years for loss of FH expression by tissue microarray (TMA)-based immunohistochemical staining. Mutational analysis of tumours with loss of FH was carried out by polymerase chain reaction (PCR) amplification of 10 exons within the FH gene and subsequent Sanger sequencing. The status of promoter methylation was assessed by bisulphite sequencing. Loss of FH protein expression was detected in seven (4.6%) of 153 tested uterine leiomyomas from young patients. All FH-negative leiomyomas displayed staghorn vasculature and fibrillary/neurophil-like cytoplasm. We found that six (86%) of seven FH-negative tumours detected by immunohistochemistry harboured FH mutations, 50% of which contained germline mutations. In particular, the germline mutational rate in FH gene was 2.0% (three of 153 cases). Bisulphite sequencing analysis failed to detect promoter methylation in any of the seven tumours. CONCLUSION:Our study showed a relatively high rate of FH germline mutation in FH-negative uterine leiomyomas from patients aged up to 30 years. While genetic mutations confer protein expression loss, epigenetic regulation of the FH gene appears to be unrelated to this phenotype.
