Sentinel Lymph Node

前哨淋巴结
  • 文章类型: Journal Article
    宫颈癌是我国乃至世界范围内的公共卫生问题。不到25%的病例在早期被诊断出来,五年生存率超过90%。这里,我们回顾宫颈癌早期的手术治疗。
    在MEDLINE数据库中进行了文献综述。搜索主要限于英语,优先考虑有或没有荟萃分析和随机研究的系统评价。然而,仅发现了一些主题的回顾性或观察性证据.
    早期宫颈癌的标准治疗方法是子宫切除术,其根本性质将取决于肿瘤的大小,淋巴血管渗透,和肿瘤特异性预后因素。此外,手术类型(子宫切除术或子宫切除术)将取决于患者保持生育能力的愿望。节点评估被指示为来自用PLV的IAI阶段的治疗的一部分。然而,前哨淋巴结在治疗中更相关。子宫切除术后宫颈癌的偶然发现需要进行多学科评估以确定治疗方法。在低风险人群中,较不彻底的手术被描述为肿瘤学安全。
    近几十年来,早期手术治疗取得了进展,使其更加个性化,并在不影响患者生存的情况下降低发病率。
    UNASSIGNED: Cervical cancer is a public health problem in our country and worldwide. Less than 25% of cases are diagnosed in the early stages, where survival is more remarkable than 90% at five years. Here, we review surgical treatment in the early stages of cervical cancer.
    UNASSIGNED: A literature review was carried out in the MEDLINE database. The search was mainly limited to the English language, with priority given to systematic reviews with or without meta-analysis and randomized studies. However, only retrospective or observational evidence was found for some topics.
    UNASSIGNED: The standard treatment for early-stage cervical cancer is hysterectomy, and its radical nature will depend on the tumor size, lymphovascular permeation, and tumor-specific prognostic factors. Furthermore, the type of surgery (hysterectomy or trachelectomy) will rely on the patient\'s desire to preserve fertility. Nodal evaluation is indicated as part of the treatment from stage IAI with PLV. However, the sentinel lymph node is more relevant in the treatment. The incidental finding of cervical cancer after a hysterectomy requires a multidisciplinary evaluation to determine the therapeutic approach. Less radical surgery has been described as oncologically safe in low-risk groups.
    UNASSIGNED: Surgical treatment in its early stages has evolved in recent decades, making it more individualized and seeking less morbidity in patients without compromising their survival.

    背景:存在许多用于子宫内膜癌的前哨淋巴结(SLN)超分期方案,但是没有共识的方法。
    目的:本研究旨在制定子宫内膜癌SLN评估的大小标准指南,为了确定单个细胞角蛋白AE1:AE3免疫组织化学载玻片是否为诊断提供了足够的数据,并比较大型三级护理机构当前和有限的超稳定方案之间的成本效率。
    方法:我们当前的SLN超稳定方案包括在两个水平(L1和L2)上切割两个相邻的石蜡块切片,相距50μm,用苏木精和曙红和细胞角蛋白AE1染色每个水平的两张载玻片:AE3免疫组织化学。我们回顾性回顾了2013年1月至2020年1月期间子宫内膜癌治疗患者所有阳性超暂住SLN的数字化L1和L2切片。SLN诊断是通过测量单个横截面中最大的连续肿瘤细胞簇定义的:大转移(>2.0mm),微转移(>0.2至≤2.0mm或>200个细胞),或分离的肿瘤细胞(≤0.2mm或≤200个细胞)。评估L1和L2结果之间的一致性。比较了当前(每个块两个免疫组织化学载玻片)和建议的有限(每个块一个免疫组织化学载玻片)方案之间的成本效率。
    结果:对来自109例患者的147个阳性SLN的数字化切片进行了回顾;根据精确的大小标准对4.1%的SLN进行了重新分类。在91.8%的SLN中看到了L1和L2解释之间的完全一致。观察到使用有限方案检测微转移和大转移的假阴性率为0%-0.9%。有限方案的估计费用水平节省为每位患者50%。
    结论:SLN解释中的高诊断准确性可以通过每块一个免疫组织化学载玻片的有限超稳定方案和最大的连续肿瘤细胞簇的线性测量来实现。所提出的有限的超稳定协议的实施可能会导致实验室成本节省,而对健康结果的影响最小。
    BACKGROUND: Many sentinel lymph node (SLN) ultrastaging protocols for endometrial cancer exist, but there is no consensus method.
    OBJECTIVE: This study aims to develop guidelines for size criteria in SLN evaluation for endometrial cancer, to determine whether a single cytokeratin AE1:AE3 immunohistochemical slide provides sufficient data for diagnosis, and to compare cost efficiency between current and limited ultrastaging protocols at a large tertiary care institution.
    METHODS: Our current SLN ultrastaging protocol consists of cutting two adjacent paraffin block sections at two levels (L1 and L2), 50 μm apart, with two slides at each level stained with hematoxylin and eosin and cytokeratin AE1:AE3 immunohistochemistry. We retrospectively reviewed digitized L1 and L2 slides of all positive ultrastaged SLNs from patients treated for endometrial cancer between January 2013 and January 2020. SLN diagnosis was defined by measuring the largest cluster of contiguous tumor cells in a single cross section: macrometastasis (>2.0 mm), micrometastasis (>0.2 to ≤2.0 mm or >200 cells), or isolated tumor cells (≤0.2 mm or ≤200 cells). Concordance between L1 and L2 results was evaluated. Cost efficiency between current (two immunohistochemical slides per block) and proposed limited (one immunohistochemical slide per block) protocols was compared.
    RESULTS: Digitized slides of 147 positive SLNs from 109 patients were reviewed; 4.1% of SLNs were reclassified based on refined size criteria. Complete concordance between L1 and L2 interpretations was seen in 91.8% of SLNs. A false-negative rate of 0%-0.9% in detecting micrometastasis and macrometastasis using a limited protocol was observed. Estimated charge-level savings of a limited protocol were 50% per patient.
    CONCLUSIONS: High diagnostic accuracy in SLN interpretation may be achieved using a limited ultrastaging protocol of one immunohistochemical slide per block and linear measurement of the largest cluster of contiguous tumor cells. Implementation of the proposed limited ultrastaging protocol may result in laboratory cost savings with minimal impact on health outcomes.

    目的:本研究的目的是就宫颈癌前哨淋巴结(SLN)清扫的手术技术达成共识。
    方法:一项26个问题的调查通过电子邮件发送给国际妇科肿瘤外科专家。采用两步改进的德尔菲法建立共识。经过第一轮在线调查,问题被修改,第二轮,进行了半结构化访谈。共识是使用70%的协议截止来定义的。
    结果:38位专家中有25位(65.8%)对第一轮和第二轮在线调查做出了回应。在第一轮中,有13个(50.0%)问题达成了≥70%的协议,在最后一轮中达成了15个(57.7%)的协议。共识协议确定了15个建议,三个可选,5个不推荐的步骤专家同意以下推荐的程序:使用吲哚菁绿作为示踪剂;在3点和9点进行表面(有或没有深度)注射;在未受累的粘膜边缘注射,避免阴道孔;用镊子抓住子宫颈,仅在子宫颈的一部分没有肿瘤;在简单的行囊/锥形切开术的情况下,使用微创方法进行SLN活检;识别输尿管切除术,脐动脉闭塞,SLN切除前和髂外血管;在子宫动脉水平开始解剖并横向继续;在进入对侧之前完成一个半骨盆的解剖。在建议6点和12点不注射方面也达成了共识,并在肿瘤完全替代子宫颈的情况下直接注射到肿瘤中;防止在没有保护性操作的情况下通过端口去除节点;没有超稳定方案;并防止在标测失败后重新注射时改变示踪剂浓度。
    结论:推荐,可选,根据国际专家的共识,确定了不推荐的宫颈癌SLN解剖步骤。这些代表了外科指南,可供外科医生在临床试验中使用,并在常规实践中用于质量保证。
    OBJECTIVE: The purpose of this study was to establish a consensus on the surgical technique for sentinel lymph node (SLN) dissection in cervical cancer.
    METHODS: A 26 question survey was emailed to international expert gynecological oncology surgeons. A two-step modified Delphi method was used to establish consensus. After a first round of online survey, the questions were amended and a second round, along with semistructured interviews was performed. Consensus was defined using a 70% cut-off for agreement.
    RESULTS: Twenty-five of 38 (65.8%) experts responded to the first and second rounds of the online survey. Agreement ≥70% was reached for 13 (50.0%) questions in the first round and for 15 (57.7%) in the final round. Consensus agreement identified 15 recommended, three optional, and five not recommended steps. Experts agreed on the following recommended procedures: use of indocyanine green as a tracer; superficial (with or without deep) injection at 3 and 9 o\'clock; injection at the margins of uninvolved mucosa avoiding vaginal fornices; grasping the cervix with forceps only in part of the cervix is free of tumor; use of a minimally invasive approach for SLN biopsy in the case of simple trachelectomy/conization; identification of the ureter, obliterated umbilical artery, and external iliac vessels before SLN excision; commencing the dissection at the level of the uterine artery and continuing laterally; and completing dissection in one hemi-pelvis before proceeding to the contralateral side. Consensus was also reached in recommending against injection at 6 and 12 o\'clock, and injection directly into the tumor in cases of the tumor completely replacing the cervix; against removal of nodes through port without protective maneuvers; absence of an ultrastaging protocol; and against modifying tracer concentration at the time of re-injection after mapping failure.
    CONCLUSIONS: Recommended, optional, and not recommended steps of SLN dissection in cervical cancer have been identified based on consensus among international experts. These represent a surgical guide that may be used by surgeons in clinical trials and for quality assurance in routine practice.

    韩国妇科肿瘤学会(KSGO)一直在努力通过制定2021年更新的临床实践指南来标准化和提高国内子宫体癌治疗的质量。KSGO根据文献检索使用4个关键要素修订了指南:人口,干预,比较,结果框架。这些要素包括评估免疫检查点抑制剂治疗在铂类化疗失败的复发/晚期子宫内膜癌患者中的疗效和安全性。以及曲妥珠单抗联合治疗HER2/neu阳性子宫内膜癌患者的效果。此外,该指南评估了低风险子宫内膜癌患者省略淋巴结清扫术的有效性和安全性,探讨前哨淋巴结定位在早期子宫内膜癌手术中的作用,讨论了化疗作为晚期(III-IVA期)子宫内膜癌患者术后治疗的结果,探讨免疫检查点抑制剂初始治疗对晚期或复发子宫内膜癌患者生存率的影响。
    The Korean Society of Gynecologic Oncology (KSGO) had been making an effort to standardize and enhance the quality of domestic uterine corpus cancer treatment by developing updated clinical practice guidelines in 2021. The KSGO revised the guidelines based on a literature search using 4 key elements: Population, Intervention, Comparison, and Outcome framework. These elements include the evaluation of the efficacy and safety of immune checkpoint inhibitor treatment in recurrent/advanced endometrial cancer patients who have failed platinum-based chemotherapy, as well as the effect of combined treatment with trastuzumab in patients with HER2/neu-positive endometrial cancer. Additionally, the guideline assessed the efficacy and safety of omitting lymph node dissection in low-risk endometrial cancer patients, investigated the effect of sentinel lymph node mapping in early-stage endometrial cancer surgery, addressed the outcome of chemoradiation therapy as a postoperative treatment in patients with advanced (stage III-IVA) endometrial cancer, and explored the impact of initial treatment with immune checkpoint inhibitors on survival in patients with advanced or recurrent endometrial cancer patients.

    目的:已知肥胖既是子宫内膜癌的主要危险因素,也与手术复杂性相关。因此,肥胖患者的管理对外科医生和肿瘤学家来说是一个挑战.这项研究的目的是评估病态肥胖患者(体重指数(BMI)>40kg/m2)对欧洲妇科肿瘤学会(ESGO)指南的遵守情况。次要目标是对总生存期和无复发生存期的影响。
    方法:所有在FRANCOGYN组的11个癌症研究所接受子宫内膜癌治疗的患者均被纳入,并分为三个体重组:病态(BMI>40kg/m2),肥胖(BMI30-40),正常或超重(BMI<30)。对手术治疗指南的依从性进行了评估,淋巴结分期,和辅助治疗。
    结果:总计,包括2375例患者:正常或超重组1330例,肥胖组763人,病态组282人。病态组的手术治疗仅在30%的病例中符合指南,肥胖组为44%,正常或超重组为48%(p<0.001);这主要是因为缺乏淋巴结分期.与肥胖组(52%)或正常或超重组(46%)相比,病态组患者更有可能接受推荐的辅助治疗(61%)(p<0.001)。体重对总生存率没有影响(p=0.6),病态组患者的无复发生存率更好(p=0.04)。
    结论:病态组患者对国际外科治疗指南的依从性明显较低,尤其是淋巴结分期.然而,病态肥胖患者更经常接受适当的辅助治疗.病态组患者的无复发生存率较好,可能是由于肿瘤预后较好。
    OBJECTIVE: Obesity is known to be both a major risk factor for endometrial cancer and associated with surgical complexity. Therefore, the management of patients with obesity is a challenge for surgeons and oncologists. The aim of this study is to assess the adherence to European Society of Gynaecological Oncology (ESGO) guidelines in morbidly obese patients (body mass index (BMI) >40 kg/m2). The secondary objectives were the impact on overall survival and recurrence-free survival.
    METHODS: All the patients who were treated for an endometrial cancer in the 11 cancer institutes of the FRANCOGYN group were included and classified into three weight groups: morbid (BMI >40 kg/m2), obese (BMI 30-40), and normal or overweight (BMI <30). Adherence to guidelines was evaluated for surgical management, lymph node staging, and adjuvant therapies.
    RESULTS: In total, 2375 patients were included: 1330 in the normal or overweight group, 763 in the obese group, and 282 in the morbid group. The surgical management of the morbid group was in accordance with the guidelines in only 30% of cases, compared with 44% for the obese group and 48% for the normal or overweight group (p<0.001); this was largely because of a lack of lymph node staging. Morbid group patients were more likely to receive the recommended adjuvant therapy (61%) than the obese group (52%) or the normal or overweight group (46%) (p<0.001). Weight had no impact on overall survival (p=0.6) and morbid group patients had better recurrence-free survival (p=0.04).
    CONCLUSIONS: Adherence to international guidelines for surgical management is significantly lower in morbid group patients, especially for lymph node staging. However, morbidly obese patients had more often the adequate adjuvant therapies. Morbid group patients had a better recurrence-free survival likely because of better prognosis tumors.

    默克尔细胞癌(MCC)是一种对放射敏感的肿瘤,在最近发布的德国科学医学会(AWMF)关于默克尔细胞癌的S2k指南的更新中,对放射疗法在这种疾病的治疗中的作用进行了新定义。虽然肿瘤床的辅助放疗被广泛推荐,前哨淋巴结阴性和高危因素的患者可以进行区域淋巴结区域的照射。在前哨淋巴结阳性的患者中,它是完成淋巴结清扫术的替代方法。辅助放疗的标准剂量仍为50Gy。
    Merkel cell carcinoma (MCC) is a radiosensitive tumor and the role of radiotherapy in the management of this disease was newly defined in the recently published update of the S2k guideline on Merkel cell carcinoma of the Association of Scientific Medical Societies in Germany (AWMF). While adjuvant radiotherapy of the tumor bed is broadly recommended, irradiation of the regional nodal region can be performed in patients with negative sentinel lymph nodes and high-risk factors. In patients with positive sentinel lymph nodes, it is an alternative to completion lymphadenectomy. The standard dose for adjuvant radiotherapy remains 50 Gy.

    背景:少数族裔服务医院(MSH)与各种癌症的指南依从性较低和预后较差有关。然而,MSH状态之间的关系,符合前哨淋巴结活检(SLNB)指南,皮肤黑色素瘤患者的总生存期(OS)尚未得到很好的研究。
    方法:国家癌症数据库查询了诊断为T1a*的患者,2012年至2017年之间的T2和T3黑色素瘤。MSH被定义为按接受黑色素瘤治疗的少数民族比例排名最高的机构。根据国家综合癌症网络指南,指南一致护理(GCC)定义为如果厚度<0.76mm无溃疡,则不进行SLNB,有丝分裂≥1/mm2,或淋巴管浸润(T1a*),并对1.0至4.0mm(T2/T3)的中等厚度黑色素瘤患者进行SLNB。多变量逻辑回归分析了与GCC的关联。Kaplan-Meier方法和对数秩检验用于评估MSH和非MSH设施之间的OS。
    结果:总体而言,整体队列中的5.9%(N=2182/36,934)和37.8%的少数民族(n=199/527)在MSH中得到了管理。总体队列中GCC率为89.5%(n=33,065/36,934),少数亚组为85.4%(n=450/527)。总体队列(比值比[OR]0.85;p=0.02)和少数亚组(OR0.55;p=0.02)中的患者如果在MSH与非MSH接受治疗,则获得GCC的可能性较小。与非MSH相比,接受MSH治疗的少数患者的生存率降低(p=0.002)。
    结论:MSHs对黑色素瘤SLNB指南的依从性较低。在美国,需要继续关注黑色素瘤少数患者的治疗公平性。
    BACKGROUND: Minority-serving hospitals (MSHs) have been associated with lower guideline adherence and worse outcomes for various cancers. However, the relationship among MSH status, concordance with sentinel lymph node biopsy (SLNB) guidelines, and overall survival (OS) for patients with cutaneous melanoma is not well studied.
    METHODS: The National Cancer Database was queried for patients diagnosed with T1a*, T2, and T3 melanoma between 2012 and 2017. MSHs were defined as the top decile of institutions ranked by the proportion of minorities treated for melanoma. Based on National Comprehensive Cancer Network guidelines, guideline-concordant care (GCC) was defined as not undergoing SLNB if thickness was < 0.76 mm without ulceration, mitosis ≥ 1/mm2, or lymphovascular invasion (T1a*), and performing SLNB for patients with intermediate thickness melanomas between 1.0 and 4.0 mm (T2/T3). Multivariable logistic regressions examined associations with GCC. The Kaplan-Meier method and log-rank tests were used to evaluate OS between MSH and non-MSH facilities.
    RESULTS: Overall, 5.9% (N = 2182/36,934) of the overall cohort and 37.8% of minorities (n = 199/527) were managed at MSHs. GCC rates were 89.5% (n = 33,065/36,934) in the overall cohort and 85.4% (n = 450/527) in the minority subgroup. Patients in the overall cohort (odds ratio [OR] 0.85; p = 0.02) and the minority subgroup (OR 0.55; p = 0.02) were less likely to obtain GCC if they received their care at MSHs compared with non-MSHs. Minority patients receiving care at MSHs had a decreased survival compared with those treated at non-MSHs (p = 0.002).
    CONCLUSIONS: Adherence to SLNB guidelines for melanoma was lower at MSHs. Continued focus is needed on equity in melanoma care for minority patients in the United States.

    迫切需要对皮肤鳞状细胞癌(cSCC)进行循证治疗,特别是“高风险”肿瘤。我们对皮肤癌专家进行了在线调查,以评估cSCC研究重点。受访者是通过国际皮肤癌成果联盟(SCOUT)和英国地区皮肤癌成果东北(SCONE)研究兴趣小组进行的。33名受访者完成了调查([46%;16/33]是非英国的)。“定义前哨淋巴结活检(SLNB)在高风险cSCC中的作用”是受访者最常排名第一或第二的研究优先级(55%;18/33),在高风险的cSCC中,SLNB可用于早期识别淋巴结转移的几乎完全共识(97%;30/31)。关于这一具体的研究重点,确定了24项具有纵向随访数据的研究。累计,cSCC的SLNB阳性率和误漏率分别为7.0%和3.1%,分别,假阴性率为29.0%。鉴于对“高风险”cSCC的定义缺乏共识,毫不奇怪,只有两项针对头颈部cSCC的SLNB研究采用了可比较的选择标准;报告总体阳性率最高(8.0%),漏报率最低(2.4%)和假阴性率(21.4%).SLNB在“高风险”cSCC中的作用受到了多学科的关注。它似乎在头部和颈部病例中表现最好。迫切需要“高风险”cSCC的共识定义,以完善SLNB的效用并指导风险导向管理。
    There is an urgent need for evidence-based management of cutaneous squamous cell carcinoma (cSCC), particularly \"high-risk\" tumours. We performed an online survey of skin cancer specialists to assess cSCC research priorities. Respondents were targeted via the international Skin Cancer OUTcomes consortium (SCOUT) and the UK regional Skin Cancer Outcomes North-East (SCONE) research interest group. Thirty-three respondents completed the survey ([46%; 16/33] were non-UK based). \'Defining a role for sentinel lymph node biopsy (SLNB) in high-risk cSCC\' was most commonly ranked either 1st or 2nd research priority by respondents (55%; 18/33), with near-total consensus that SLNB could be useful for the early identification of nodal metastasis in high-risk cSCC (97%; 30/31). On this specific research priority, 24 studies with longitudinal follow-up data were identified. Cumulatively, SLNB for cSCC had positivity and false omission rates of 7.0% and 3.1%, respectively, with false negative rates of 29.0%. Given the lack of consensus on a definition of \"high-risk\" cSCC, it was unsurprising that only two studies of SLNB for head & neck cSCC utilised comparable selection criteria; reporting the highest positivity rates (8.0%) and lowest false-omission rates (2.4%) and false-negative rates (21.4%) overall. There is multi-disciplinary interest in the role of SLNB for \"high-risk\" cSCC. It appears to perform best in head and neck cases. A consensus definition of \"high-risk\" cSCC is urgently required to refine the utility of SLNB and guide risk-directed management.

    Data suggest variation in utilization of completion lymph node dissection (CLND) and adjuvant systemic therapy (AT) for sentinel lymph node-positive melanoma. We aimed to explore how clinicians consider multidisciplinary treatment options.
    We conducted semi-structured interviews of surgical oncologists, medical oncologists, and otolaryngologists to produce a thematic analysis.
    Participants (n = 26) described melanoma care as inherently \"multidisciplinary,\" noting the importance of conversations facilitated by shared clinic days or space. Despite believing that their practice mirrored other clinicians, participants revealed diverging perspectives on CLND and AT. Multidisciplinary care presented challenges for surveillance as surgeons expressed desire to retain ownership of patients but did not feel comfortable overseeing AT needs. Participants questioned the fidelity of nodal ultrasounds, noted redundancy in their roles, and described a \"surveillance burden\" for patients.
    Opportunities exist to improve multidisciplinary melanoma care through broader consensus of how to translate emerging data into patient care and delineating surveillance roles.
