实时超声支气管镜引导下经支气管针吸活检术对肺癌的诊断作用

评价实时超声支气管镜引导下的经支气管针吸活检术（EBUS-TBNA）对肺癌的诊断价值。方法:回顾分析中山大学肿瘤防治中心2010年8月至2011年2月期间,46例经胸部CT或PET-CT检查显示为纵隔和/或肺门淋巴结肿大和/或胸内气管旁肿块（≥1 cm）的患者行EBUS-TBNA的资料（其中临床拟诊为肺癌并肺门和/或纵隔淋巴结转移25例,纵隔和/或肺门不明原因淋巴结肿大21例）,统计实时EBUS-TBNA在肺癌诊断中的敏感性、特异性、阳性预测值、阴性预测值及诊断率。结果:46例患者中,其中经病理学检查确诊为肺癌患者38例,淋巴结结核3例,淋巴结炎3例,结节病1例,淋巴瘤1例。46例患者中,经EBUS-TBNA诊断为肺癌34例,淋巴结核2例,淋巴结炎3例,结节病1例。38例肺癌患者共穿刺48组淋巴结,1例气管旁肿物,其中经EBUS-TBNA诊断为肺癌34例,假阴性4例,敏感性为89.5%,特异性为100%,阳性预测值为100%,阴性预测值为66.7%,诊断率为87.0%。EBUS-TBNA过程安全,全部病例无严重并发症发生,仅1例一过性发热。结论:实时EBUS-TBNA,并发症少,可在门诊进行,且诊断率、敏感性及阴性预测值高,是诊断肺癌安全、有效的方法。当常规支气管镜未能取到阳性病理结果时,亦可尝试通过对肺门或纵隔淋巴结或肺内肿块行EBUS-TBNA来诊断。

目的探讨超声支气管镜引导下针吸活检术（EBUS TBNA）在非小细胞肺癌（NSCLC）诊断及其淋巴结分期评估中的价值。方法选取新疆医科大学第八附属医院2019年8月至2020年8月收治的经胸部CT检查显示纵隔或肺门淋巴结肿大或肺内肿块疑似肺癌的患者118例,均行EBUS TBNA检查,以病理学诊断结果为最终诊断,分析EBUS TBNA对NSCLC的诊断价值,并探查所有可及的纵隔与肺门淋巴结,对淋巴结试行穿刺,分析穿刺部位分布、EBUS TBNA诊断分型、EBUS TBNA对NSCLC淋巴结分期评估价值及并发症。结果118例患者中有116例经临床病理学诊断确诊为NSCLC,经EBUS TBNA检查确诊111例,准确度为9407%（111/118）,灵敏度为9569%（111/116）,特异度为10000%（2/2）,阳性预测值为10000%（111/111）,阴性预测值为2857%（2/7）。116例患者经EBUS TBNA检查共获得来自不同部位的142个淋巴结样本,其中纵隔淋巴结108个,肺门淋巴结34个,4R、7、11R为最常累及的淋巴结。EBUS TBNA检查对纵隔淋巴结和肺门淋巴结评估的灵敏度分别为9485%、7917%,特异度分别为10000%、10000%,阳性预测值分别为10000%、10000%,阴性预测值分别为6875%、6667%,准确度分别为9537%、8529%,Kappa值分别为0789、0691,与病理诊断结果的一致性良好。EBUS TBNA评估NSCLC淋巴结N0、N1、N2、N3期的准确度分别为9500%、9444%、9792%、9167%。共有6例（517%）患者发生轻微并发症,经相关处理后均有所好转。结论EBUS TBNA对NSCLC及淋巴结分期均有较高的诊断价值。     

Endobronchial ultrasound guided transbronchial needle aspiration for staging of lung cancer

During the staging process of lung cancer, accurate mediastinal lymph node staging is one of the important factors which affect patient management. The purpose of the current study was to evaluate the usefulness of direct real-time endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) for staging and diagnosis of lung cancer in patients with mediastinal lymph nodes suspected of malignancy and to assess the impact of this method in patient management. One hundred and eight patients with mediastinal lymph nodes with known or suspected lung cancer were included. The convex probe EBUS integrated with a convex scanning probe on its tip was used in all cases. Final diagnosis was based on cytology, surgical results, and/or clinical follow-up.

In 105 patients, EBUS-TBNA was successfully performed to obtain samples from 163 lymph nodes. With respect to the correct prediction of lymph node stage, EBUS-TBNA had a sensitivity of 94.6%, specificity of 100%, positive predictive value of 100%, negative predictive value of 89.5%, and diagnostic accuracy rate of 96.3%. In the 20 suspected lung cancer cases, mediastinal lymph node was used for tissue diagnosis of malignancy as well as staging. As a result of EBUS-TBNA, 29 mediastinoscopies, 8 thoracotomies, 4 thoracoscopies, and 9 CT-guided PCNB were avoided. The procedure was uneventful without complications. EBUS-TBNA is a safe and sensitive method for lymph node staging in patients with lung cancer. It spares invasive staging procedures which has a major impact on patient management.     

非小细胞肺癌患者术前EBUS-TBNA淋巴结分期与术后病理分期一致性探讨

目的:探索术前超声引导下支气管镜针吸活检术(EBUS-TBNA)淋巴结活检结果与术后病理结果的一致性。方法:回顾性纳入本院2013年1月至2017年12月期间符合纳入标准的、不符合排除标准的非小细胞肺癌患者。以术后病理为金标准,分析术前EBUS-TBNA淋巴结活检的敏感性和特异性等。结果:研究纳入了80例符合纳入标准、不符合排除标准的患者,平均年龄61.1岁,男性占73.8%,病理类型包括腺癌、鳞癌、腺鳞癌等。EBUS-TBNA未见明显并发症,对于全部103枚EBUS-TBNA活检淋巴结,EBUS-TBNA检测的敏感性为96.15%、特异性为100.00%、阳性预测值为100.00%、阴性预测值为89.29%。结论:EBUS-TBNA纵隔淋巴结活检是安全的,对于转移淋巴结判断的敏感性、特异性、阳性预测值、阴性预测值均较高。     

Mantle cell lymphoma in lymph nodes with metastatic small cell carcinoma of lung: a diagnostic and treatment dilemma

We report a rare case of small cell carcinoma (SCC) of lung, metastatic to ipsilateral hilar and peribronchial lymph nodes with synchronous mantle cell lymphoma (MCL), in a 58-year-old female. She was treated with Cisplatin, Etoposide, and Rituximab, and remained in complete remission for approximately two and a half years following the initial diagnosis. To the best of our knowledge, synchronous SCC and MCL or SCC metastatic to lymph nodes involved by MCL has not been previously reported. In this case, the features of MCL were very inconspicuous in the lymph nodes with extensive metastases of SCC. The presence of MCL was confirmed by immunohistochemistry and fluorescence in situ hybridization (FISH). The co-existence of lymphoma and metastatic carcinoma in the same lymph node, as seen in this case, highlights the significance of analyzing subtle lymphoid architectural changes, and applying ancillary studies such as immunohistochemistry and molecular analysis in suspicious cases. The management of synchronous SCC and MCL requires consideration of their respective biologic behavior, and cumulative toxicity of treatment regimens of both tumors. In such cases an optimum treatment strategy should be adopted to cover both malignancies with minimal toxic effect.     

Endobronchial ultrasound and value of PET for prediction of pathological results of mediastinal hot spots in lung cancer patients

SUMMARY: In the staging of lung cancer with positron emission tomography (PET) positive mediastinal lymph nodes, tissue sampling is required. The performance of transbronchial needle aspiration (TBNA) using linear endobronchial ultrasound (real-time EBUS-TBNA) under local anaesthesia and the value of PET for prediction of pathological results were assessed in that setting. The number of eluded surgical procedures was evaluated. All consecutive patients with suspected/proven lung cancers and FDG-PET positive mediastinal adenopathy were included. If no diagnosis was reached, further surgical sampling was required. Lymph node SUVmax (maximum standardized uptake value) was assessed in patients whose PET was performed in the leading centre. One hundred and six patients were included. The average number of TBNA samples per patient was 4.9+/-1.1. The prevalence of lymph node metastasis was 58%. Sensitivity, accuracy and negative predictive value of EBUS-TBNA in the staging of mediastinal hot spots were 95, 97 and 91%. Patients without malignant lymph node involvement showed lower SUVmax (respective median values of 3.7 and 10.0; p<0.0001). Surgical procedures were eluded in 56% of the patients. Real-time EBUS-TBNA should be preferred over mediastinoscopy as the first step procedure in the staging of PET mediastinal hot spots in lung cancer patients. In case of negative EBUS, surgical staging procedure should be undertaken. The addition of SUVmax cut-off may allow further refinement but needs validation.     

肺癌~（18）F-FDG-PETCT的SUVmax与淋巴结转移及肺癌肿瘤标志物之间的关系研究

目的：研究肺癌18F-FDG-PETCT的SUVmax（最大标准摄取值）与肺癌淋巴结转移、肺癌肿瘤标志物、肿瘤大小及临床病理类型之间的关系。方法：经病理确认的98例肺癌住院患者,术前一周内均行18F-FDG PET-CT检查肿块大小、SUVmax及肺门或纵隔淋巴结转移情况;并进行肿瘤标志物神经元特异性烯醇化酶（NSE）、癌胚抗原（CEA）和细胞角蛋白片（CYFRA21-1）检查,统计学分析检测结果。结果：原发灶SU-Vmax与原发灶大小之间存在相关性（r=0.497,P〈0.05）,与单个肿瘤标志物的值之间无明显相关性。整体分析时肺门或纵隔淋巴结转移组与无转移组的原发灶SUVmax均值之间差异无统计学意义,腺癌肺门或纵隔淋巴结转移组及无转移组的SUVmax均数之间差异有统计学意义（P〈0.05）。鳞癌肺门或纵隔淋巴结转移组及无转移组的SUVmax均数之间差别无统学意义（P=0.721）。肺鳞癌与腺癌SUVmax均值之间比较差异有统计学意义（P=0.001）;细支气肺泡癌与其它腺癌SUVmax均值之间差异有统计学意义（P〈0.05）。结论：在病理类型不明确的情况下原发灶SUVmax的高低并不能预测淋巴结转移的有无,肺腺癌原发灶FDG代谢活性与肺门和（或）纵隔淋巴结转移有关,淋巴结转移率随着肿块SUVmax的增加而增加;肺鳞癌FDG代谢活性与肺门和（或）纵隔淋巴结转移无关。SUVmax与病理类型有关,鳞癌SUVmax较高,腺癌较低,细支气管肺泡癌则更低。

EBUS-TBNA和纵隔镜检查术在纵隔淋巴结诊断与分期中的对照研究

以影像学纵隔淋巴结异常的患者为研究对象,比较EBUS-TBNA和纵隔镜检查术诊断纵隔淋巴结转移和肺癌纵隔分期的价值。方法:对纵隔淋巴结异常的患者先行EBUS-TBNA,不管EBUS-TBNA的结果如何,再行纵隔镜检查术。以病理结果或临床随访为标准,比较两者在诊断纵隔淋巴结转移和肺癌纵隔分期中的价值。结果:2009年12月至2011年4月期间,共33例患者纳入分析,其中23例最后确诊为肺癌,10例为良性病变;EBUS-TBNA和纵隔镜检查术对肺癌纵隔淋巴结分期的敏感性、特异性和准确率相同,分别为90.0%、100%和91.3%;诊断肺癌纵隔淋巴结转移的敏感性、特异度和准确率分别为88.5%、100%、91.4%和80.8%、100%、85.7%,差异无统计学意义;3例开胸术的患者未发现新的纵隔淋巴结转移;EBUS-TBNA检出90%（18/20）的阳性患者,但其中仅5例诊断出癌细胞或非小细胞肺癌;5组纵隔镜检查术假阴性的淋巴结有2组位于隆突下淋巴结。结论:EBUS-TBNA在肺癌纵隔分期和纵隔淋巴结转移诊断中的价值与纵隔镜检查术相似,两者具有互补性。对EBUS-TBNA阴性或者病理不能具体分型的患者,需再行纵隔镜检查术。      

Maximizing the yield of lymph node cytology: Lessons learned from rapid onsite evaluation of image- and endoscopic-guided biopsies of hilar and mediastinal lymph nodes

The evaluation of mediastinal and hilar lymph nodes for tissue diagnosis and staging of lung cancer is now commonly performed by minimally invasive, nonsurgical procedures such as computed tomography-guided fine-needle aspiration and endobronchial ultrasound-guided transbronchial needle aspiration. Ensuring that a sufficient quantity of cellular material has been acquired to enable multiple studies has become a priority issue in the era of personalized medicine, especially for patients with lung cancer, and this can be accomplished by rapid onsite evaluation (ROSE). This commentary focuses on the use of ROSE in guided procedures, especially for hilar and mediastinal lymph node aspirates, and describes an algorithm for handling these specimens.     

Lymph node cancer of the mediastinal or hilar region with an unknown primary site

We herein report three cases of lymph node cancer of the mediastinal or hilar region, in which the primary sites could not be determined in spite of performing various systemic examinations. Two cases revealed a large cell anaplastic carcinoma in the mediastinal lymph node, while the other demonstrated a small cell carcinoma in the hilar lymph node. However, based on radiographic and pathological examinations, the primary sites could not be found in either the head and neck, lung, or abdominal organs. All cases underwent surgical resections for lymph node cancer, while two patients also received adjuvant therapy. Two patients experienced recurrence soon after treatment. Despite the rarity of this disease, lymph node cancer must always be kept in mind when an enlargement of either the mediastinal or hilar lymph node is detected in patients with an unknown primary site, and a poor prognosis is generally expected. © 1995 Wiley-Liss, Inc.     

Successful treatment for metastases from renal cell carcinoma with alternation of interferon-alpha subtypes

Here we present a case in which alternation of interferon-alpha (IFN-α) treatments was effective in treating pulmonary metastases and lymph node metastases from renal cell carcinoma (RCC). A 56-year-old man underwent left radical nephrectomy under the diagnosis of left RCC. The histological diagnosis was clear cell carcinoma G2, IFN-α, pT1b. He subsequently underwent two operations for right pulmonary metastasis and right hilar lymph node metastasis. Postoperatively he was treated with intramuscular administration of natural IFN-α (Sumiferon) which prevented definite recurrence for 1 year. However, multiple pulmonary metastases and left hilar lymph node metastasis occurred 11 months after discontinuation of Sumiferon. Therefore, treatment with another natural IFN-α (OIF) was started. Although OIF was continued for 7 months, pulmonary metastases and left hilar lymph node metastasis continued to progress. Therefore, treatment was changed to Sumiferon, after which the pulmonary metastases and left hilar lymph node metastasis decreased in size. The metastases showed no progression for 16 months after switching from OIF to Sumiferon.     

EBUS-TBNA超声内镜对纵隔肿大淋巴结良恶性的鉴别诊断价值

目的:分析超声内镜引导下经支气管针吸活检(endobronchial ultrasound-guided transbronchial needle aspiration,EBUS-TBNA)术中肿大纵隔淋巴结的超声图像特点,探讨EBUS-TBNA超声内镜对纵隔淋巴结良恶性的鉴别诊断价值,以期提高EBUS-TBNA对纵隔淋巴结恶性病变的活检率。方法:回顾性分析2014年10月至2018年11月行EBUS-TBNA患者的超声内镜图像。我们使用以下EBUS超声内镜特征来预测淋巴结的良恶:回声,长轴长度,短轴长度,纵横比,形态,边界,淋巴门有无,淋巴结内血流信号分级。将超声检查结果与最终病理结果或临床随访结果进行比较。采用SPSS 20.0软件进行统计学分析,采用logistic回归分析评价肿大淋巴结EBUS-TBNA超声内镜下的特征与良恶性的相关性,以 P<0.05 为标准判定差异有统计学意义。结果:对130例纵隔淋巴结肿大患者的227个淋巴结进行回顾性分析,67.4%的肿大淋巴结被证实为恶性转移。Logistic回归分析显示回声、长轴及短轴的长度、正常淋巴门结构的消失是诊断恶性淋巴结的独立预测因素。结论:纵隔恶性淋巴结具有一定的超声特征,可以通过这些超声特征提高EBUS-TBNA对纵隔恶性淋巴结的检出率。     

支气管超声弹性成像技术对肺门及纵隔淋巴结良恶性鉴别诊断的临床价值*

目的: 探讨支气管超声弹性成像技术在肺门及纵隔淋巴结良恶性鉴别诊断中的临床价值。 方法: 选取2015年3月至2017年6月就诊于兰州大学第二医院行胸部CT提示肺门或纵隔淋巴结肿大,常规行经支气管镜超声引导针吸活检术（endobronchial ultrasound-guided tansbronchial needle aspiration,EBUS-TBNA）检查的68例患者,共穿刺121枚淋巴结,分别对目标淋巴结行支气管镜下超声及弹性成像检查,记录常规超声和弹性成像的各个参数。以EBUS-TBNA穿刺的病理结果作为诊断的“金标准”,计算常规超声和弹性成像各个参数的诊断敏感度和特异性,运用Logistic回归分析,评价对肿大淋巴结良恶性鉴别诊断的临床价值。 结果: 采用超声弹性成像蓝色面积的比例,作为鉴别诊断良恶性淋巴结的最佳诊断界值为0.6,诊断的准确率为87.10%,敏感度为89.20%,特异性为79.33%,阳性预测值为89.23%,阴性预测值为72.31%,受试者工作特征（receiver operator characteristic,ROC）曲线下面积为0.902,诊断价值明显高于常规超声下各参数和弹性评分;Logistic回归分析显示肺门和纵隔肿大淋巴结中影响其良恶性的主要因素为超声下病变短径、边界、回声均匀、血供及弹性成像蓝色面积的比例。 结论: 超声弹性成像蓝色面积的比例对肺门和纵隔淋巴结良恶性的鉴别诊断以及精准引导EBUS-TBNA操作具有较高的临床价值。      

经支气管镜淋巴结针吸活检对肺癌的诊断意义

目的评价经支气管镜淋巴结针吸活检（TBNA）在纵隔肺门肿大淋巴结诊断中的作用。方法对CT检查发现纵隔肺门淋巴结肿大,但估计支气管镜检查不能发现气管或支气管内新生物的77例患者,在支气管镜检查过程中完成TBNA操作,直接涂片送检。结果38例诊断为肺癌,35例诊断为肺部良性疾病,4例最终无明确诊断。77例患者共穿刺128个部位,225针,其中TBNA穿刺成功222针（98．7％）。35例肺部良性疾病的TBNA总结果均为阴性。38例肺癌患者中,TBNA总结果阳性31例（81．6％）,其中9例患者TBNA涂片为惟一病理学证据。38例肺癌患者共穿刺63个淋巴结,其中TBNA结果阳性41例（65．1％）。TBNA结果的阳性率与病理类型和淋巴结大小有关。TBNA不良反应很少,52例（67．5％）患者穿刺部位少量出血。结论TBNA安全性好,对肺癌的诊断和分期判定有很大帮助,但对肺部良性疾病的诊断帮助不大。
