    目的:为接受卵巢刺激(OS)的高反应患者的管理提供一致的指南方法:对辅助生殖技术的OS高反应的管理进行了文献检索。由4位专家组成的科学委员会进行了讨论,修正,并选择了最后的陈述。先验,决定在超过66%的参与者同意时达成共识,≤3轮将用于获得这一共识。共有28/31名专家作了答复(选定为全球覆盖),彼此匿名。
    结果:共有26/28份声明达成共识。最相关的总结在这里。在预期的超反应者中,在IVF的刺激周期中收集的卵母细胞的目标数目是15-19(89.3%一致)。对于一个潜在的超响应者来说,与新转移的目标相比,实现超反应和冻结是优选的(71.4%的共识)。在进行IVF的预期高反应者中,应避免使用GnRH激动剂来抑制垂体(96.4%共识)。预期的平均体重的超应答者的第一IVF刺激周期中的优选起始剂量为150IU/天(82.1%共识)。为了降低OHSS的风险,不应使用ICoasting(89.7%共识)。只有在患者患有PCOS且胰岛素抵抗(82.1%共识)的情况下,才应在卵巢刺激之前/期间将二甲双胍添加到预期的高反应者。在过度反应的情况下,只有当hCG在有或没有新鲜转移的情况下用作触发剂(包括双重/双重触发剂)时,才应使用多巴胺能药物(67.9%共识).在使用GnRH激动剂触发器后,由于感知到的OHSS风险,无论收集的卵母细胞数量如何,都不鼓励使用hCG进行黄体期挽救和尝试新鲜转移(72.4%共识)。FET方案的选择不受患者是超应答者(82.8%共识)的事实的影响。在冻结的情况下,都是由于OHSS风险,FET周期可以在第一个月经周期立即进行(92.9%共识)。
    结论:这些超反应管理指南可用于定制患者护理和协调未来的研究。
    OBJECTIVE: To provide agreed-upon guidelines on the management of a hyper-responsive patient undergoing ovarian stimulation (OS) METHODS: A literature search was performed regarding the management of hyper-response to OS for assisted reproductive technology. A scientific committee consisting of 4 experts discussed, amended, and selected the final statements. A priori, it was decided that consensus would be reached when ≥66% of the participants agreed, and ≤3 rounds would be used to obtain this consensus. A total of 28/31 experts responded (selected for global coverage), anonymous to each other.
    RESULTS: A total of 26/28 statements reached consensus. The most relevant are summarized here. The target number of oocytes to be collected in a stimulation cycle for IVF in an anticipated hyper-responder is 15-19 (89.3% consensus). For a potential hyper-responder, it is preferable to achieve a hyper-response and freeze all than aim for a fresh transfer (71.4% consensus). GnRH agonists should be avoided for pituitary suppression in anticipated hyper-responders performing IVF (96.4% consensus). The preferred starting dose in the first IVF stimulation cycle of an anticipated hyper-responder of average weight is 150 IU/day (82.1% consensus). ICoasting in order to decrease the risk of OHSS should not be used (89.7% consensus). Metformin should be added before/during ovarian stimulation to anticipated hyper-responders only if the patient has PCOS and is insulin resistant (82.1% consensus). In the case of a hyper-response, a dopaminergic agent should be used only if hCG will be used as a trigger (including dual/double trigger) with or without a fresh transfer (67.9% consensus). After using a GnRH agonist trigger due to a perceived risk of OHSS, luteal phase rescue with hCG and an attempt of a fresh transfer is discouraged regardless of the number of oocytes collected (72.4% consensus). The choice of the FET protocol is not influenced by the fact that the patient is a hyper-responder (82.8% consensus). In the cases of freeze all due to OHSS risk, a FET cycle can be performed in the immediate first menstrual cycle (92.9% consensus).
    CONCLUSIONS: These guidelines for the management of hyper-response can be useful for tailoring patient care and for harmonizing future research.

    进行了Delphi共识,以评估编码促性腺激素和促性腺激素受体的基因中的单核苷酸多态性(SNP)对辅助生殖技术(ART)治疗后的临床卵巢刺激结果的影响。
    九位专家和两位科学协调员讨论和修改了声明,以及科学协调员提出的支持参考资料。声明通过在线调查分发给36名专家,他们对每项声明的同意或分歧进行了投票。如果同意或不同意声明的参与者比例>66%,则达成共识。
    开发了11个声明,其中两个语句被合并。总的来说,八项声明达成共识,两项声明未达成共识。这里总结了达成共识的声明。(1)卵泡刺激素受体(FSHR)中的SNP,rs6166(c.2039A>G,p.Asn680Ser)(N=5个陈述):Ser/Ser载体具有比Asn/Asn载体更高的基础FSH水平。Ser/Ser携带者在卵巢刺激期间需要比Asn/Asn携带者更高的促性腺激素。Ser/Ser携带者在卵巢刺激过程中产生的卵母细胞比Asn/Asn或Asn/Ser携带者少。有混合证据支持这种变异与卵巢过度刺激综合征之间的关联。(2)FSHR的SNP,rs6165(c.919G>A,p.Thr307Ala)(N=1声明):很少有研究表明Thr/Thr携带者比Thr/Ala或Ala/Ala携带者需要更短的促性腺激素刺激持续时间。(3)FSHR的SNP,rs1394205(-29G>A)(N=1声明):特定种族的有限数据表明,A/A等位基因携带者在卵巢刺激期间可能需要更高的促性腺激素,并且比G/G携带者产生更少的卵母细胞。(4)FSHβ链(FSHB)的SNP,rs10835638(-211G>T)(N=1陈述):有矛盾的证据支持该变体与基础FSH水平或卵母细胞数量之间的关联。(5)黄体生成素β链(LHB)和LH/绒毛膜促性腺激素受体(LHCGR)基因的SNP(N=1声明):这些可能会影响卵巢刺激结果,并可能代表ART药物基因组学研究的潜在未来目标。尽管数据仍然非常有限。
    本德尔菲共识提供了来自不同国际专家组的临床观点。共识支持促性腺激素/促性腺激素受体基因中的一些变异与卵巢刺激结果之间的联系;然而,需要进一步的研究来澄清这些发现.
    A Delphi consensus was conducted to evaluate the influence of single nucleotide polymorphisms (SNPs) in genes encoding gonadotropin and gonadotropin receptors on clinical ovarian stimulation outcomes following assisted reproductive technology (ART) treatment.
    Nine experts plus two Scientific Coordinators discussed and amended statements plus supporting references proposed by the Scientific Coordinators. The statements were distributed via an online survey to 36 experts, who voted on their level of agreement or disagreement with each statement. Consensus was reached if the proportion of participants agreeing or disagreeing with a statement was >66%.
    Eleven statements were developed, of which two statements were merged. Overall, eight statements achieved consensus and two statements did not achieve consensus. The statements reaching consensus are summarized here. (1) SNP in the follicle stimulating hormone receptor (FSHR), rs6166 (c.2039A>G, p.Asn680Ser) (N=5 statements): Ser/Ser carriers have higher basal FSH levels than Asn/Asn carriers. Ser/Ser carriers require higher amounts of gonadotropin during ovarian stimulation than Asn/Asn carriers. Ser/Ser carriers produce fewer oocytes during ovarian stimulation than Asn/Asn or Asn/Ser carriers. There is mixed evidence supporting an association between this variant and ovarian hyperstimulation syndrome. (2) SNP of FSHR, rs6165 (c.919G>A, p.Thr307Ala) (N=1 statement): Few studies suggest Thr/Thr carriers require a shorter duration of gonadotropin stimulation than Thr/Ala or Ala/Ala carriers. (3) SNP of FSHR, rs1394205 (-29G>A) (N=1 statement): Limited data in specific ethnic groups suggest that A/A allele carriers may require higher amounts of gonadotropin during ovarian stimulation and produce fewer oocytes than G/G carriers. (4) SNP of FSH β-chain (FSHB), rs10835638 (-211G>T) (N=1 statement): There is contradictory evidence supporting an association between this variant and basal FSH levels or oocyte number. (5) SNPs of luteinizing hormone β-chain (LHB) and LH/choriogonadotropin receptor (LHCGR) genes (N=1 statement): these may influence ovarian stimulation outcomes and could represent potential future targets for pharmacogenomic research in ART, although data are still very limited.
    This Delphi consensus provides clinical perspectives from a diverse international group of experts. The consensus supports a link between some variants in gonadotropin/gonadotropin receptor genes and ovarian stimulation outcomes; however, further research is needed to clarify these findings.

    This guideline reviews the clinical evaluation and management of gestational trophoblastic diseases, including surgical and medical management of benign, premalignant, and malignant entities. The objective of this guideline is to assist health care providers in promptly diagnosing gestational trophoblastic diseases, to standardize treatment and follow-up, and to ensure early specialized care of patients with malignant or metastatic disease.
    General gynaecologists, obstetricians, family physicians, midwives, emergency department physicians, anaesthesiologists, radiologists, pathologists, registered nurses, nurse practitioners, residents, gynaecologic oncologists, medical oncologists, radiation oncologists, surgeons, general practitioners in oncology, oncology nurses, pharmacists, physician assistants, and other health care providers who treat patients with gestational trophoblastic diseases. This guideline is also intended to provide information for interested parties who provide follow-up care for these patients following treatment.
    Women of reproductive age with gestational trophoblastic diseases.
    Women diagnosed with a gestational trophoblastic disease should be referred to a gynaecologist for initial evaluation and consideration for primary surgery (uterine evacuation or hysterectomy) and follow-up. Women diagnosed with gestational trophoblastic neoplasia should be referred to a gynaecologic oncologist for staging, risk scoring, and consideration for primary surgery or systemic therapy (single- or multi-agent chemotherapy) with the potential need for additional therapies. All cases of gestational trophoblastic neoplasia should be discussed at a multidisciplinary cancer case conference and registered in a centralized (regional and/or national) database.
    Relevant studies from 2002 onwards were searched in Embase, MEDLINE, the Cochrane Central Register of Controlled Trials, and Cochrane Systematic Reviews using the following terms, either alone or in combination: trophoblastic neoplasms, choriocarcinoma, trophoblastic tumor, placental site, gestational trophoblastic disease, hydatidiform mole, drug therapy, surgical therapy, radiotherapy, cure, complications, recurrence, survival, prognosis, pregnancy outcome, disease outcome, treatment outcome, and remission. The initial search was performed in April 2017 and updated in May 2019. Relevant evidence was selected for inclusion in the following order: meta-analyses, systematic reviews, guidelines, randomized controlled trials, prospective cohort studies, observational studies, non-systematic reviews, case series, and reports. Additional significant articles were identified through cross-referencing the identified reviews. The total number of studies identified was 673, with 79 studies cited in this review.
    The content and recommendations were drafted and agreed upon by the authors. The Executive and Board of Directors of the Society of Gynecologic Oncology of Canada reviewed the content and submitted comments for consideration, and the Board of Directors for the Society of Obstetricians and Gynaecologists of Canada approved the final draft for publication. The quality of evidence was rated using the criteria described in the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology framework. See the online appendix tables for key to grading and interpretation of recommendations.
    These guidelines will assist physicians in promptly diagnosing gestational trophoblastic diseases and urgently referring patients diagnosed with gestational trophoblastic neoplasia to gynaecologic oncology for specialized management. Treating gestational trophoblastic neoplasia in specialized centres with the use of centralized databases allows for capturing and comparing data on treatment outcomes of patients with these rare tumours and for optimizing patient care.

    Hydatidiform mole is treated with surgical uterine evacuation with suction and blunt curettage (D). Medical uterine evacuation should not be used (C). On clinical suspicion of hydatidiform mole, one representative sample of the evacuated tissue is fixed for histopathologic investigation and one is forwarded unfixed for genetic analysis (D). Serum hCG is measured on suspicion of hydatidiform mole. At the time of the uterine evacuation, the initial hCG is measured (A). After a hydatidiform mole that is both triploid and partial, serum hCG is measured weekly until there are two consecutive undetectable values (< 1 or < 2), after which the patient can be discharged from follow-up (C). After a diploid hydatidiform mole, a complete mole, or a hydatidiform mole without valid ploidy determination, serum hCG is measured weekly until the value is undetectable (< 1 or < 2). If serum hCG is undetectable within 56 days after evacuation, the patient can be discharged from follow-up after an additional four monthly measurements. If serum hCG is first normalised after 56 days, the patient is follow-up with monthly serum hCG measurement for six months. Safe contraception should be used during the follow-up period (A). If hCG stagnates (less than 10% fall over three measurements), increases, or if hCG can be demonstrated for longer than 6 months, the patient by definition has persistent trophoblastic disease (PTD). A chest X-ray should be taken and a gynaecologic ultrasound scanning performed. The patient is referred to oncologic treatment (A). Uterine re-evacuation as a treatment for PTD can, in general, not be recommended because the rate of remission is low, and there is the risk of perforation of the uterus (C). In all following pregnancies, the woman is offered an early ultrasound scan, e.g. in gestational week eight (D). Eight weeks after termination of all future pregnancies, serum hCG is measured (D). In PTD and invasive hydatidiform mole, the primary treatment is MTX, either orally every third week or IV every week (B). In MTX-resistant PTD, IV act D is added (or replaces the MTX) (B). Third line chemotherapy is BEP or EP, alternatively EMA-CO (B). Choriocarcinoma is primarily treated with chemotherapy. Hysterectomy and/or resection of metastases are possible treatments (A). Placental site trophoblastic tumour (PSTT) and epithelioid trophoblastic tumour (ETT) are primarily treated with hysterectomy. In the case of disseminated disease, chemotherapy is considered (A). The risk of reoccurrence after trophoblastic disease treated with chemotherapy is approximately 3%. Most reoccurrences are seen within 12 months, and for this reason monitoring of hCG is recommended for one year, the first third months once or twice a month, thereafter every second to third month. Patients with PSTT and ETT are monitored with measurement of hCG throughout their lifetimes (C). In genetically verified twin pregnancy with hydatidiform mole and a living foetus, the pregnancy can continue if serum hCG is monitored and ultrasound scans regularly performed, and possible obstetric complications dealt with (C). In the case of recurrent hydatidiform mole and/or familial hydatidiform mole, patients should be referred to genetic workup and counselling (C). Women with a hereditary disposition to hydatidiform mole because of a mutation in NLRP7 should be informed of the possibility of becoming pregnant via egg donation (C).

    目的:评估超声检查的价值,hCG和孕酮用于诊断妊娠早期无活力妊娠和评估妊娠早期流产管理(疏散除外)。
    方法:使用PubMed搜索法语和英语出版物,科克伦图书馆和国际学会的建议。
    结果:孕前3个月无活力妊娠是以妊娠囊平均直径和胚胎冠-臀部长度确定的。经阴道超声检查,无胚胎的平均囊径≥25mm(LE2)或无心跳的胚胎冠-臀部长度≥7mm(LE2)可以诊断妊娠失败。不确定生存能力的宫内妊娠定义为子宫内妊娠囊,无心跳或无妊娠诊断失败,需要进行新的经阴道超声检查。第二次超声检查的延迟取决于宫内图像的方面(即是否存在卵黄囊,是否存在胚胎)(LE4)。人绒毛膜促性腺激素(hCG)和孕酮可用于未知位置的妊娠(即经阴道超声检查无孕囊):当第一个hCG<2000UI/mL(LE2)或低血清孕酮水平(<3.2ng/mL)(LE2)时,两天血清样品之间的hCG比率<15%。没有已知的先兆流产预防策略。
    OBJECTIVE: To assess value of sonography, hCG and progesterone for diagnosis of first trimester nonviable pregnancy and to assess first trimester miscarriage management (except evacuation).
    METHODS: French and English publications were searched using PubMed, Cochrane Library and international learned societies recommendations.
    RESULTS: First trimester nonviable pregnancy is established with gestational sac mean diameter and embryo crown-rump length. Mean sac diameter≥25mm without embryo (LE2) or embryo crown-rump length≥7mm without heartbeat (LE2) by transvaginal sonography allows to diagnose pregnancy failure. Intrauterine pregnancy of uncertain viability is defined by intra-uterine gestational sac without embryo with heartbeat or without pregnancy diagnosis failure and requires a new transvaginal sonography. The delay for this second sonography depends on the aspect of intrauterine picture (i.e. presence of yolk sac or not, presence of embryo or not) (LE4). Human chorionic gonadotropin (hCG) and progesterone are useful for pregnancy of unknown location (i.e. no gestational sac at transvaginal sonography): hCG ratio<15% between two-day serum samples when first hCG is<2000UI/mL (LE2) or low serum progesterone level (<3.2ng/mL) (LE2) exclude viable intrauterine pregnancy. There is not known prevention strategy for threatened miscarriage.

  • 文章类型: English Abstract
    Cryptorchidism, or undescended testis (UDT), occurs in 1-3% of male term infant births. At least two-thirds of UDTs will descend spontaneously, typically during the first 6 months of life. UDTs are associated with loss of spermatogenic potential and testicular malignancy in the long term. Orchiopexy performed prior to puberty may significantly reduce the malignant potential by up to 4-fold. Neoadjuvant hormonal therapy starting at 6 months of life has been shown to potentially improve the testicle\'s fertility index and should be part of the therapeutic concept. However, the use of hormonal treatment and HCG beyond the first year of life is to be challenged given a potentially negative impact on testicular function. Laparoscopic exploration and therapy is the method of choice for non-palpable testes. Ideally, surgical repair of the UDT should be completed by the age of 1 year.

    背景:肿瘤标志物(TM)的不适当使用是一个常见问题。此审核的目的是评估当地指南对普外科部门TM请求模式的影响。
    方法:CA125,CA19-9,CA15-3,CEA,在实施本地请求指南之前和之后的两个八个月中,对所有医院手术地点的AFP和HCG请求进行了审核。
    结果:干预后,总TM请求减少了32%,而患者请求减少了9.8%。单个TM请求增加,对包含四个或更多TM的面板的请求从279个减少到60个请求(减少78%)。
    结论:部门间的合作和当地指南的实施导致了请求行为的变化,最值得注意的是多个TM面板请求的减少。
    BACKGROUND: The inappropriate use of tumour markers (TMs) is a common problem. The aim of this audit was to evaluate the impact of local guidelines on the TM requesting patterns of a General Surgery Department.
    METHODS: CA 125, CA 19-9, CA15-3, CEA, AFP and HCG requests from all hospital surgical locations were audited over two periods of eight months before and after the implementation of local requesting guidelines.
    RESULTS: Postintervention, total TM requests decreased by 32% while patient requests decreased by 9.8%. Single TM requesting increased and requests for panels containing four or more TMs decreased from 279 to 60 requests (78% reduction).
    CONCLUSIONS: Interdepartmental collaboration and the implementation of local guidelines have resulted in a change in requesting behaviour, most notably a reduction in multiple TM panel requests.

    背景:已经发布了异位妊娠(EP)的循证指南,涵盖诊断和治疗管理。总的来说,指南旨在减少实践差异并提高护理质量。为了评估EP管理中的指南依从性,我们制定了基于指南的质量指标,并测量了各医院的患者护理.
    方法:专家和临床医生小组根据荷兰EP管理指南的建议制定了质量指标,使用系统的RAND改进的德尔菲法。有了这些指标,在2003年1月至2005年12月期间,在6家荷兰医院对患者护理进行了评估.对于每个质量指标,计算了指南依从性的比率.报告了总体依从性,以及每种医院类型的依从性,即学术,教学和非教学医院。
    结果:在30个基于指南的建议中,选择了12项质量指标,涵盖程序,护理的结构和结果方面。对于317名接受EP手术治疗的妇女,对这些方面进行了评估。对指南的总体依从性为75%。在诊断检查期间,经阴道超声检查的依从性最高(98%)。在对侧输卵管病理的情况下,进行输卵管切开术的依从性最低(21%)。学术之间的坚持差异很大(0-100%),教学和非教学医院。
    结论:总体指南依从性是合理的,在护理的各个方面都有足够的改进空间。进一步的研究应侧重于准则传播和遵守的障碍,进一步完善EP的管理。
    BACKGROUND: Evidence-based guidelines have been issued for ectopic pregnancy (EP), covering both diagnostic and therapeutic management. In general, guidelines aim to reduce practice variation and to improve quality of care. To assess the guideline adherence in the management of EP, we developed guideline-based quality indicators and measured patient care in various hospitals.
    METHODS: A panel of experts and clinicians developed quality indicators based on recommendations from the Dutch guideline on EP management, using the systematic RAND-modified Delphi method. With these indicators, patient care was assessed in six Dutch hospitals between January 2003 and December 2005. For each quality indicator, a ratio for guideline adherence was calculated. Overall adherence was reported, as well as adherence per hospital type, i.e. academic, teaching and non-teaching hospitals.
    RESULTS: Out of 30 guideline-based recommendations, 12 quality indicators were selected covering procedural, structural and outcome aspects of care. For 317 women surgically treated for EP, these aspects were assessed. Overall adherence to the guideline was 75%. The highest adherence (98%) was observed for performing transvaginal sonography during the diagnostic workup. The lowest adherence (21%) was observed for performing salpingotomy in case of contra-lateral tubal pathology. Wide variance in adherence (0-100%) existed between academic, teaching and non-teaching hospitals.
    CONCLUSIONS: The overall guideline adherence was reasonable, with ample room for improvement in various aspects of care. Further research should focus on the barriers for guideline dissemination and adherence, to further improve the management of EP.

    肝细胞癌(HCC),与大多数实体瘤不同,可以进行非侵入性诊断。我们提出了一个案例,强调了两个既定指南之间的重要临床差异:国家癌症综合网络(NCCN)和巴塞罗那-2000EASL会议(欧洲肝脏研究协会)。我们的患者有一个大的肝脏肿块,延伸到右心房,甲胎蛋白升高到1,130ng/mL。使用NCCN指南,放射学和实验室证据足以启动HCC的姑息治疗。Barcelona-2000EASL会议的非侵入性诊断指南仅限于肝硬化患者。我们的患者没有慢性肝病或活动性肝炎的病史,活检显示乳腺癌。
    Hepatocellular carcinoma (HCC), unlike most solid tumors, can be diagnosed noninvasively. We present a case that highlights an important clinical difference between two established guidelines: National Cancer Comprehensive Network (NCCN) and Barcelona-2000 EASL Conference (European Association for the Study of the Liver). Our patient had a large liver mass extending into the right atrium with elevation of the alpha-fetoprotein to 1,130 ng/mL. The radiographic and laboratory evidence is sufficient using NCCN guidelines to initiate palliative treatment for HCC. The Barcelona-2000 EASL Conference guideline for noninvasive diagnosis is restricted to cirrhotic patients. Our patient did not have a history of chronic liver disease or active hepatitis, and a biopsy was performed that demonstrated breast cancer.
