BACKGROUND:The prognostic value and optimal resection outcome related factors of the secondary cytoreduction surgery (SCR) in Platinum-sensitive recurrent ovarian cancer (PSOC) patients were still in doubt. The present retrospective study aims to determine the relationship between the objective response of secondary neo-adjuvant chemotherapy (SNAC) and the resection outcome of SCR. METHODS:Data were reviewed from 142 type II PSOCs who underwent SCR in Jiangsu Institute of Cancer Research between 1996 and 2016. Among them, 55 cases received preliminary Platinum based SNAC before SCR. Logistic regression analysis was used to explore optimal SCR related factors. Cox proportional hazards model and log-rank test were used to assess the associations between the survival durations and covariates. RESULTS:Optimal initial CRS (p = 0.02), disappearance of ascites after SNAC (p = 0.04) recurrent status (p = 0.02) and longer Platinum-free interval (p = 0.01) were the independent indicators of optimal SCR. Optimal SCR was associated with time to progression (TTP) but not overall survival (OS) (p = 0.04 and p = 0.41). The TTP and OS of PSOCs underwent SNAC were similar to those patients underwent SCR (p = 0.71, and p = 0.77, respectively) directly. CONCLUSIONS:SNAC might be another choice for PSOCs were not suitable for directly SCR. Optimal SCR had survival benefit in PSOCs whenever underwent SNAC or not.


背景: 在铂类敏感的复发性卵巢癌 (PSOC) 患者中,二次肿瘤细胞减灭术 (SCR) 的预后价值和最佳切除结局相关因素仍存在疑问。本回顾性研究旨在确定二次新辅助化疗 (SNAC) 的客观反应与 SCR 切除结局之间的关系。 方法: 对江苏省肿瘤研究所 1996 ~ 142 年间接受 SCR 的 2016 例 ⅱ 型 PSOCs 进行回顾性分析。其中,55 例在 SCR 前接受了以铂类为基础的 SNAC 的初步治疗。采用 Logistic 回归分析探讨最佳 SCR 相关因素。采用 Cox 比例风险模型和 log-rank 检验评估生存时间和协变量之间的相关性。 结果: 最佳初始 CRS (p = 0.02),SNAC 后腹水消失 (p = 0.04) 复发状态 (p = 0.02) 和较长的无铂间期 (p = 0.01) 是最佳 SCR 的独立指标。最佳 SCR 与进展时间 (TTP) 相关,但与总生存期 (OS) 无关 (p = 0.04 和 p = 0.41)。PSOCs 接受 SNAC 的 TTP 和 OS 与直接接受 SCR 的患者相似 (分别为 p = 0.71 和 p = 0.77)。 结论: SNAC 可能是 PSOCs 不适合直接 SCR 的另一种选择。无论是否接受 SNAC,最佳 SCR 在 PSOCs 中均有生存获益。

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.
