针吸活检
  • 文章类型: Journal Article
    目的:本研究的目的是探讨经皮移植活检的安全性和有效性,特别是在接受机器人肾移植的患者中,一个在现有文献中受到有限关注的话题。虽然经皮移植活检已在接受开放移植的患者中得到了很好的证实,其在机器人移植中的应用仍未被探索。材料和方法:对2013年至2024年的患者记录进行回顾性分析,重点是由于急性移植物功能障碍而接受移植物活检的患者。该队列分为两个不同的组:接受开放性肾脏移植的个体和接受机器人肾脏移植的个体。结果:该研究共包括89名患者,其中64人接受了开放性肾移植,25人接受了机器人辅助肾移植。患者平均年龄为40.61(±12.26)岁,男性60人(67.4%),女性29人(32.6%)。比较分析显示,年龄没有显著差异,性别分布,身体质量指数,供体类型(尸体与活体),或两组之间的移植物丢失率。此外,对总并发症发生率的检查未发现队列之间有任何显著差异.结论:在基于适应症和协议活检的情况下,超声辅助经皮穿刺活检是接受机器人辅助肾脏移植的患者的可靠方法。这项研究强调了超声辅助经皮穿刺活检作为机器人辅助肾移植患者可行方法的可靠性。通过阐明在机器人移植背景下经皮移植活检的安全性和有效性,这项研究有助于扩大该领域的知识体系,为临床实践和未来的研究工作提供有价值的见解。
    Objective: The objective of this study was to investigate the safety and efficacy of percutaneous graft biopsy, specifically in patients who have undergone robotic kidney transplantation, a topic that has received limited attention in the existing literature. While percutaneous graft biopsy is well established in patients who have undergone open transplantation, its application in robotic transplantation remains relatively unexplored. Material and Methods: A retrospective analysis was conducted on patient records spanning from 2013 to 2024, focusing on those who underwent graft biopsy due to acute graft dysfunction. The cohort was bifurcated into two distinct groups: individuals who underwent open kidney transplantation and those who underwent robotic kidney transplantation. Results: The study encompassed a total of 89 patients, with 64 having undergone open kidney transplantation and 25 having undergone robot-assisted kidney transplantation. The mean age of the patients was 40.61 (±12.26) years, with 60 (67.4%) being male and 29 (32.6%) being female. Comparative analysis revealed no significant disparities in age, gender distribution, body mass index, donor type (cadaveric versus living), or rates of graft loss between the two groups. Furthermore, examination of the total complication rates did not uncover any noteworthy differences between the cohorts. Conclusions: Ultrasound-assisted percutaneous needle biopsy is a reliable method in patients who have undergone robot-assisted kidney transplantation in cases of both indication-based and protocol biopsies. This study underscores the reliability of ultrasound-assisted percutaneous needle biopsy as a viable method for patients who have undergone robot-assisted kidney transplantation. By shedding light on the safety and efficacy of percutaneous graft biopsy in the context of robotic transplantation, this research contributes to the expanding body of knowledge in the field, providing valuable insights for clinical practice and future research endeavors.

    目的:甲状腺细针穿刺细胞学(FNA)和粗针活检(CNB),唾液腺,和淋巴结被认为是微创组织收集的简单和快速的方法。我们进行了一项邮政调查,以分析德国FNA和CNB的诊断价值和并发症发生率。
    方法:2015年9月,向所有161个德国耳鼻喉科发送了包含11个问题的问卷。
    结果:有效率为45%。在73个有反应的诊所中,有33个既没有进行FNA也没有进行CNB。在提供详细原因的26个诊所中,大多数(n=18)提到合作的病理学家缺乏专业知识.总的来说,FNA更常用,无论研究的解剖区域。该研究基于总共36,684FNA和9,624CNB。FNA的估计有意义和正确的发现率为63%(10%-90%),CNB为83%(50%-100%)。在8例(<0.001%)中,报告了潜在的肿瘤细胞扩散。
    结论:这是德国首次全国性调查,旨在调查FNA和CNB在头颈部不同位置的效用。这项研究揭示了有关FNA和CNB诊断价值的文献结果。仅在个别病例中观察到细胞扩散。在德国,对头部和颈部区域的针活检的评估似乎相当不均匀。
    OBJECTIVE: Fine-needle aspiration cytology (FNA) and core needle biopsy (CNB) of the thyroid gland, salivary glands, and lymph nodes are considered simple and rapid methods for minimally invasive tissue collection. We performed a postal survey to analyse the diagnostic value and complication rate of FNA and CNB in Germany.
    METHODS: A questionnaire comprising 11 questions was sent to all 161 German ENT departments in September 2015.
    RESULTS: The response rate was 45%. In 33 of the 73 responding clinics neither FNA nor CNB were carried out. Of the 26 clinics that provided detailed reasons, the majority (n=18) cited a lack of expertise among the collaborating pathologists. Overall, FNA was used more often, regardless of the anatomical region investigated. The study was based on a total of 36,684 FNAs and 9,624 CNBs. The rate of estimated meaningful and correct findings was 63% (10%-90%) for FNA, and 83% (50%-100%) for CNB. In eight cases (<0.001%) a potential tumor cell spread was reported.
    CONCLUSIONS: This is the first nationwide survey in Germany to investigate the utility of FNA and CNB across different localizations in the head and neck region. This study revealed comparable results to the literature regarding the diagnostic value of FNA and CNB. Cell spreading was only observed in individual cases. The appraisal of needle biopsies in the head and neck area seems to be rather inhomogeneous in Germany.

    UNASSIGNED: This study investigated whether the respiratory phase during pleural puncture in CT-guided percutaneous transthoracic needle biopsy (PTNB) affects complications.
    UNASSIGNED: We conducted a retrospective review of 477 lung biopsy CT scans performed during free breathing. The respiratory phases during pleural puncture were determined based on the table position of the targeted nodule using CT scans obtained during free breathing. We compared the rates of complications among the inspiratory, mid-, and expiratory respiratory phases. Logistic regression analysis was performed to control confounding factors associated with pneumothorax.
    UNASSIGNED: Among the 477 procedures, pleural puncture was performed during the expiratory phase in 227 (47.6%), during the mid-phase in 108 (22.6%), and during the inspiratory phase in 142 (29.8%). The incidence of pneumothorax was significantly lower in the expiratory puncture group (40/227, 17.6%; p = 0.035) and significantly higher in the mid-phase puncture group (31/108, 28.7%; p = 0.048). After controlling for confounding factors, expiratory-phase puncture was found to be an independent protective factor against pneumothorax (odds ratio = 0.571; 95% confidence interval = 0.360-0.906; p = 0.017).
    UNASSIGNED: Our findings suggest that pleural puncture during the expiratory phase may reduce the risk of pneumothorax during image guided PTNB.
    UNASSIGNED: 전산화단층촬영(이하 CT) 유도 경피 폐 생검에서 흉막 천자 시에 호흡 시기가 합병증 발생에 영향을 미치는지 조사하는 것이다.
    UNASSIGNED: 자유 호흡 중 시행된 폐 생검의 CT 스캔 477개를 후향적으로 검토하였다. 흉막 천자 시 호흡 시기는 자유 호흡 중 얻은 CT 영상에서 목표 결절의 table position의 차이로 분석 평가하였다. 세 가지 호흡 시기(흡기, 중간, 호기)에서의 합병증 발생률을 비교하였다. 기흉에 대한 교란변수를 통제하기 위해 로지스틱 회귀 분석을 하였다.
    UNASSIGNED: 477건의 시술 중에서 흉막 천자는 227건(47.6%)에서 호기, 108건(22.6%)에서 중기, 142건(29.8%)에서 흡기에서 시행되었다. 기흉 발생률은 호기에서 유의하게 낮았고(40/227, 17.6%; p = 0.035) 중기에서 유의하게 높았다(31/108, 28.7%; p = 0.048). 교란변수를 통제한 후, 호기 시 흉막 천자는 기흉에 대해 독립적인 보호 요인으로 작용하였다(오즈비 = 0.571; 95% 신뢰구간 = 0.360–0.906; p = 0.017).
    UNASSIGNED: 본 연구 결과는 이미지 유도하 경피적 폐 생검시 호기에서 흉막 천자를 시행하는 것이 기흉 발생률을 감소시킬 수 있음을 보여주었다.

    最近提出了Gleason分数的5层分组。研究表明这些组中的预后异质性。我们评估了在基于人群的国家队列中,在针吸活检中诊断为Gleason评分3+5=8、4+4=8和5+3=8腺泡腺癌的男性的前列腺癌特异性死亡率(PCSM)和全因死亡率(ACM)。以5年和10年的PCSM和ACM作为终点,使用瑞典前列腺癌数据库5.0进行生存分析。控制社会经济因素的多变量Cox回归模型,PCSM和ACM采用分期和初级治疗类型。在2000-2020年报告患有前列腺癌的199,620名男性中,有172,112人在穿刺活检中被诊断出。在18,281(11%)中,针活检的格里森得分为8分,包括11%的3+5、4+4和5+3的格里森评分,86%和2.3%,分别。主要治疗是雄激素剥夺治疗(55%),延期治疗(8%),前列腺癌根治术(16%)或根治性放疗(21%)。Gleason评分为3+5,4+4和5+3的男性在5年随访时PCSM为0.10(95%CI0.09-0.12),0.22(0.22-0.23)和0.32(0.27-0.36),分别,10年为0.19(0.17-0.22),0.34(0.33-0.35)和0.44(0.39-0.49),分别。Gleason评分为5+3的男性在5年和10年后的PCSM明显高于4+4的男性,而Gleason评分为4+4的男性则高于3+5的男性。Gleason评分分组将消除Gleason评分的预后粒度,从而降低了该提议的分级系统的预后意义。
    A 5-tier grouping of Gleason scores has recently been proposed. Studies have indicated prognostic heterogeneity within these groups. We assessed prostate cancer-specific mortality (PCSM) and all-cause mortality (ACM) for men diagnosed with Gleason score 3 + 5 = 8, 4 + 4 = 8 and 5 + 3 = 8 acinar adenocarcinoma on needle biopsy in a population-based national cohort. The Prostate Cancer data Base Sweden 5.0 was used for survival analysis with PCSM and ACM at 5 and 10 years as endpoints. Multivariable Cox regression models controlling for socioeconomic factors, stage and primary treatment type were used for PCSM and ACM. Among 199,620 men reported with prostate cancer in 2000-2020, 172,112 were diagnosed on needle biopsy. In 18,281 (11%), there was a Gleason score of 8 in needle biopsies, including a Gleason score of 3 + 5, 4 + 4 and 5 + 3 in 11%, 86% and 2.3%, respectively. The primary treatment was androgen deprivation therapy (55%), deferred treatment (8%), radical prostatectomy (16%) or radical radiotherapy (21%). PCSM in men with Gleason scores of 3 + 5, 4 + 4 and 5 + 3 at 5 years of follow-up was 0.10 (95% CI 0.09-0.12), 0.22 (0.22-0.23) and 0.32 (0.27-0.36), respectively, and at 10 years 0.19 (0.17-0.22), 0.34 (0.33-0.35) and 0.44 (0.39-0.49), respectively. There was a significantly higher PCSM after 5 and 10 years in men with Gleason score 5 + 3 cancers than in those with 4 + 4 and in Gleason score 4 + 4 cancers than in those with 3 + 5. Grouping of Gleason scores will eliminate the prognostic granularity of Gleason scoring, thus diminishing the prognostic significance of this proposed grading system.

    背景:图像引导或辅助的针活检以及越来越多的医疗胸腔镜(MT)的使用显着提高了胸膜疾病的诊断准确性。然而,对于哪些患者应接受内科胸腔镜检查(MT),哪些患者应接受影像引导或辅助穿刺活检作为第一程序,以确保胸腔积液患者的更高诊断准确性,目前尚无共识.
    目的:哪种活检方法更适合诊断胸腔积液的患者?
    方法:本前瞻性,随机化,平行研究包括二百二十八例未确诊的渗出性胸腔积液患者。根据计算机断层扫描(CT)发现将患者分为两组。第1组:仅有胸腔积液的患者;第2组:有胸膜增厚或病变伴胸腔积液的患者。每组患者被随机分配到影像辅助艾布拉姆斯穿刺活检(IA-ANPB)或MT组。诊断灵敏度,可靠性,并确定两组的安全性.
    结果:在第1组中,IA-ANPB臂的假阴性率为30.3%,MT臂的假阴性率为3.1%。在第2组中,IA-ANPB的比率为11.9%,MT的比率为4.7%。在第1组中,IA-ANPB臂的灵敏度为69.7%,负似然比0.30。MT组的相同比率为96.9%和0.03(p=0.009)。在第2组中,IA-ANPB臂的这些值分别为88.1%和0.12,MT臂的这些值分别为95.4%和0.05(p=0.207)。两种活检方法之间的并发症发生率没有差异(8.5%和15.8%,分别为;p=0.107)。
    结论:MT在所有胸腔积液患者中显示出较高的诊断成功率。另一方面,IA-ANPB在胸腔积液和相关的胸膜增厚/病变患者中显示出与MT相似的诊断成功率。因此,在后一种情况下,IA-ANPB在MT之前可能是优选的。
    BACKGROUND: Image-guided or assisted needle biopsies and the increasing use of medical thoracoscopy (MT) have increased the diagnostic accuracy of pleural diseases significantly. However, no consensus exists regarding which patients with pleural effusion should undergo MT and which patients should undergo image-guided or assisted needle biopsy as the first procedure to ensure greater diagnostic accuracy.
    OBJECTIVE: Which biopsy method is more appropriate for which patient to provide the highest diagnostic accuracy in the diagnosis of pleural effusion?
    METHODS: This prospective, randomized, parallel study included 228 patients with undiagnosed exudative pleural effusion. Patients were divided into two groups based on CT scan findings. Group 1 included patients with pleural effusion only. Group 2 included patients with pleural thickening or lesion in addition to pleural effusion. Patients in each group were assigned randomly to an image-assisted Abrams needle pleural biopsy (IA-ANPB) or MT arm. The diagnostic sensitivity, reliability, and safety were determined for both groups.
    RESULTS: The false-negative rate was 30.3% for the IA-ANPB arm and 3.1% for the MT arm in group 1. The same rates were 11.9% for IA-ANPB and 4.7% for MT in group 2. In group 1, the sensitivity for the IA-ANPB arm was 69.7%, and the negative likelihood ratio was 0.30. The same rates for the MT arm were 96.9% and 0.03 (P = .009). In group 2, these values were 88.1% and 0.12 for the IA-ANPB arm and 95.4% and 0.05 for the MT arm (P = .207). The rate of complications between the two biopsy methods was not different (8.5% and 15.8%, respectively; P = .107).
    CONCLUSIONS: MT showed a high diagnostic success in all patients with pleural fluid. However, IA-ANPB showed similar diagnostic success as MT in patients with pleural effusion and associated pleural thickening or lesions. Therefore, in the latter case, IA-ANPB could be preferable to MT.
    BACKGROUND: ClinicalTrials.gov; No.: NCT05428891; URL: www.

    背景:卵泡树突状细胞肉瘤(FDCS)于1986年首次发现;该疾病的特异性是其稀有性,发病率仅为0.4%,许多医生对它缺乏了解,影像诊断的准确性不高,这很容易延误治疗。本文总结了FDCS的几种特征性影像学表现,为影像医师提供对这种罕见疾病的影像学特性的认识。面对复杂的案件,放射科医师可以考虑这种疾病,并将其纳入鉴别诊断。FDCS主要发生在淋巴结,主要在头部和颈部。主要症状是疲劳,局部疼痛,或无痛肿块。治疗方法不统一,但是学者们一致认为,我们应该尽可能地争取手术的机会。
    方法:本文报告1例术后3年盆腔复发的FDCS。病人在当地医院经术后病理怀疑为淋巴瘤,建议患者定期复查。最近在左盆腔中再次发现软组织肿块。增强CT检查后,放射科医生对之前的淋巴瘤诊断持怀疑态度.随后,北京大学首钢医院进行了穿刺活检。在咨询其他医院后,病理结果拒绝了淋巴瘤的先前诊断,患者被诊断为FDCS。
    结论:FDCS的影像学表现缺乏绝对特异性,但它也具有成像特性,比如巨大肿块中大面积的坏死,肿块中有粗糙的肿块钙化,增强扫描显示“快进慢出”模式,肿瘤里有血管.FDCS主要发生于淋巴结,易误诊为GIST。炎性成肌细胞瘤,淋巴瘤等。放射科医师应继续收集这种疾病的病例,并将疑似病例纳入临床工作的鉴别诊断中。
    Follicular Dendritic Cell Sarcomas (FDCS)was first found in 1986; the specificity of the disease is its rarity, with an incidence of only 0.4%, numerous doctors for its lack of understanding, the accuracy of imaging diagnosis is not great, which is easy to delay the treatment. This article summarizes several characteristic imaging manifestations of FDCS to provide imaging physicians with an understanding of the imaging properties of this rare disease. When faced with complex cases, the radiologist can consider this disease and include it in the differential diagnosis. FDCS occurs mainly in lymph nodes, mainly in the head and neck. The main symptoms are fatigue, local pain, or painless mass. The treatment method is not uniform, but scholars agree that we should strive for the opportunity of surgery as much as possible.
    This paper reported a case of FDCS with pelvic recurrence 3 years after surgery. The patient was suspected to have lymphoma by postoperative pathology in the local hospital, and it is recommended that the patient be reexamined regularly. A soft tissue mass was recently found again in the left pelvic cavity. After an enhanced CT examination, the radiologist was skeptical of the previous diagnosis of lymphoma. Subsequently, a needle biopsy was performed at Peking University Shougang Hospital. The pathological results rejected the prior diagnosis of lymphoma after consultation with additional hospitals, and the patient was diagnosed with FDCS.
    The imaging manifestations of FDCS lack absolute specificity, but it also has imaging characteristics, such as large areas of necrosis in the huge mass, rough mass calcification in the mass, enhanced scan showed \"fast in and slow out\" mode, and there were blood vessels in the tumor. FDCS mainly occurs in lymph nodes and is easily misdiagnosed as GIST, inflammatory myoblastoma, lymphoma, etc. Radiologists should continue to collect cases of this disease and include suspected cases in the differential diagnosis in clinical work.

    目的:许多女性担心乳腺穿刺活检会增加癌症扩散的风险。这篇综述文章的目的是讨论有关穿刺活检引起的癌细胞移位的风险及其对局部和区域复发以及乳腺癌生存率的影响的乳腺癌文献。
    方法:进行了文献综述,以讨论针吸活检诱导的癌细胞移位的风险和缓解。
    结果:穿刺活检诱导的癌细胞移位是常见事件。风险受活检技术和乳腺癌类型的影响。有证据表明,穿刺活检诱导的癌细胞移位的风险可能会增加局部复发的几率,但对局部复发和长期生存没有影响。
    结论:对穿刺活检程序的技术修改可以降低乳腺穿刺活检诱导的癌细胞移位的风险,并可能降低局部复发的风险,特别是在病人的整个乳房辐射是省略。
    OBJECTIVE: Many women fear that breast needle biopsies increase the risk of cancer spread. The purpose of this review article is to discuss the breast cancer literature regarding the risk of needle-biopsy-induced cancer cell displacement and its impact on local and regional recurrence and breast cancer survival.
    METHODS: A literature review is performed to discuss the risks and mitigation of needle-biopsy-induced cancer cell displacement.
    RESULTS: Needle-biopsy-induced cancer cell displacement is a common event. The risk is influenced by the biopsy technique and the breast cancer type. Evidence suggests that the risk of needle-biopsy-induced cancer cell displacement may potentially increase the odds of local recurrence but has no impact on regional recurrence and long-term survival.
    CONCLUSIONS: Technical modifications of needle biopsy procedures can reduce the risk of breast needle-biopsy-induced cancer cell displacement and potentially reduce the risk of local recurrence, especially in patients for whom whole breast radiation is to be omitted.

    MRI引导的针活检(INB)是传统的基于框架或无框架的立体定向针活检(SNB)的新兴替代方案。INB的研究仅限于精选病例系列,INB和SNB之间的比较研究仍然是文献中的空白。我们进行了荟萃分析,以比较INB和SNB文献的诊断率,手术发病率和死亡率,肿瘤大小,和程序时间。
    我们在26项SNB研究中确定了36个单独的队列(包括无框和基于框架的活检,3374例患者)和27项INB研究(977例患者)。按比例进行Meta回归和Meta分析。
    相对于研究SNB的出版物,研究INB的出版物更可能涉及位于雄辩大脑中的脑肿瘤(79.4%对62.6%,P=0.004)或最大直径较小(INB组2.7cm与SNB组3.6cm,P=.032)。尽管存在这些差异,INB诊断率的汇总估计值高于SNB(95.4%对92.3%,P=.026)。与INB组(6.1%)相比,SNB组(12.0%)的手术发病率汇总估计值更高(P=.004)。手术后的死亡率在INB和SNB之间相当(1.7%对2.3%,P=.288)。手术时间在90.3分钟(INB)和103.7分钟(SNB)具有统计学可比性,分别(P=.526)。
    我们的荟萃分析表明,相对于SNB,INB更经常是为具有挑战性的,位于雄辩大脑中的较小尺寸的脑肿瘤。INB与较低的手术发病率和提高的诊断率相关。
    UNASSIGNED: MRI-guided needle biopsy (INB) is an emerging alternative to conventional frame-based or frameless stereotactic needle biopsy (SNB). Studies of INB have been limited to select case series, and comparative studies between INB and SNB remain a missing gap in the literature. We performed a meta-analysis to compare INB and SNB literature in terms of diagnostic yield, surgical morbidity and mortality, tumor size, and procedural time.
    UNASSIGNED: We identified 36 separate cohorts in 26 studies of SNB (including both frameless and frame-based biopsies, 3374 patients) and 27 studies of INB (977 patients). Meta-regression and meta-analysis by proportions were performed.
    UNASSIGNED: Relative to publications that studied SNB, publications studying INB more likely involved brain tumors located in the eloquent cerebrum (79.4% versus 62.6%, P = 0.004) or are smaller in maximal diameter (2.7 cm in INB group versus 3.6 cm in the SNB group, P = .032). Despite these differences, the pooled estimate of diagnostic yield for INB was higher than SNB (95.4% versus 92.3%, P = .026). The pooled estimate of surgical morbidity was higher in the SNB group (12.0%) relative to the INB group (6.1%) (P = .004). Mortality after the procedure was comparable between INB and SNB (1.7% versus 2.3%, P = .288). Procedural time was statistically comparable at 90.3 min (INB) and 103.7 min (SNB), respectively (P = .526).
    UNASSIGNED: Our meta-analysis indicates that, relative to SNB, INB is more often performed for the challenging, smaller-sized brain tumors located in the eloquent cerebrum. INB is associated with lower surgical morbidity and improved diagnostic yield.

    诊断后延迟手术切除肿瘤所带来的乳腺癌(BC)死亡率风险增加是一个日益关注的问题。然而潜在的机制仍然未知。我们对早期BC患者的队列分析显示,当活检至手术间隔延长至53天时,死亡率风险显着上升。此外,活检后肿瘤的组织学显示,由M2样巨噬细胞主导的转移许可伤口基质的保留时间延长,该巨噬细胞能够促进癌细胞上皮到间质转化和血管生成。我们表明,穿刺活检通过COX-2/PGE2/EP2前馈环的持续激活机制促进癌细胞的全身播散,它有利于M2极化及其相关的促转移变化,但在雌激素受体阳性(ER)同系小鼠肿瘤模型中,用COX-2或EP2抑制剂口服治疗可以消除。因此,我们得出的结论是,ER+BC的穿刺活检会引起进行性的前转移改变,这可以解释诊断后手术延迟带来的死亡风险。
    Increased breast cancer (BC) mortality risk posed by delayed surgical resection of tumor after diagnosis is a growing concern, yet the underlying mechanisms remain unknown. Our cohort analyses of early-stage BC patients reveal the emergence of a significantly rising mortality risk when the biopsy-to-surgery interval was extended beyond 53 days. Additionally, histology of post-biopsy tumors shows prolonged retention of a metastasis-permissive wound stroma dominated by M2-like macrophages capable of promoting cancer cell epithelial-to-mesenchymal transition and angiogenesis. We show that needle biopsy promotes systemic dissemination of cancer cells through a mechanism of sustained activation of the COX-2/PGE2/EP2 feedforward loop, which favors M2 polarization and its associated pro-metastatic changes but are abrogated by oral treatment with COX-2 or EP2 inhibitors in estrogen-receptor-positive (ER+) syngeneic mouse tumor models. Therefore, we conclude that needle biopsy of ER+ BC provokes progressive pro-metastatic changes, which may explain the mortality risk posed by surgery delay after diagnosis.
