Multiple myeloma (MM) is a bone marrow cancer that profoundly affects plasma cells involved in the immune response. Myeloma cells alter the average production of cells in the bone marrow. Anti-B-cell maturation antigen (BCMA) chimeric antigen receptor (CAR) T-cell therapy allows genetic modifications of an individual’s T-cells to increase the expression of CARs used to identify and attach BCMA proteins to the malignant cells. Our main objective is to perform a systematic review and meta-analysis to explore the efficacy and safety of anti-BCMA CAR T-cell therapy for MM.We searched five databases, PubMed, CNKI, EMBASE, Cochrane, Web of Science, and CNKI, for studies published on anti-BCMA,CAR-T-cell treatment for MM. Inclusion criteria involved prospective single-arm studies either single or multi-center, in various MM phases and studies that reported anti-BCMA,CAR-T-cell treatment for MM. We excluded non-English publications and conference papers. All statistical analyses were performed in R software and Review Manager 5.4.1.Thirteen articles were included in the analysis. We found that the overall response survival complete response increase was statistically significant. Similarly, the reduction in cytokine release syndrome grades 3 and 4 and neurotoxicity after follow-up was statistically significant. However, the reduction in minimal residual disease negativity (MRDN) was not statistically significant.Using anti-BCMA CAR T-cell therapy in MM was highly efficacious and safe in lowering the adverse outcomes and improving the survival outcomes, complete response, and overall response.
多发性骨髓瘤(MM)是一种骨髓癌,会严重影响参与免疫反应的浆细胞。骨髓瘤细胞会改变骨髓中细胞的平均产量。抗B细胞成熟抗原(BCMA)嵌合抗原受体(CAR)T细胞疗法允许对个体的T细胞进行基因修饰,以增加用于识别BCMA蛋白并将其附着在恶性细胞上的CAR的表达。我们在 PubMed、CNKI、EMBASE、Cochrane、Web of Science 和 CNKI 五个数据库中检索了有关抗 BCMA、CAR-T 细胞治疗 MM 的研究。纳入标准包括不同MM阶段的前瞻性单臂或多中心研究,以及报道抗BCMA,CAR-T细胞治疗MM的研究。我们排除了非英文出版物和会议论文。所有统计分析均使用 R 软件和 Review Manager 5.4.1 进行。我们发现,总体应答生存期完全应答的增加具有统计学意义。同样,随访后细胞因子释放综合征 3 级和 4 级以及神经毒性的减少也具有统计学意义。在 MM 中使用抗 BCMA CAR T 细胞疗法在降低不良反应、改善生存结果、完全应答和总体应答方面具有高度的有效性和安全性。

This study aimed to identify differential metabolites and key metabolic pathways between lung adenocarcinoma (LUAD) tissues and normal lung (NL) tissues using metabolomics techniques, to discover potential biomarkers for the early diagnosis of lung cancer.Forty-five patients with primary ground-glass nodules (GGN) identified on computed tomography imaging and who were willing to undergo surgery at Shanghai General Hospital from December 2021 to December 2022 were recruited to the study. All participants underwent video thoracoscopy surgery with segmental or wedge resection of the lung. Tissue samples for pathological examination were collected from the site of ground-glass nodules (GGN) lesion and 3 cm away from the lesion (NL). The pathology results were 35 lung adenocarcinoma (LUAD) cases (13 invasive adenocarcinoma, 14 minimally invasive adenocarcinoma, and eight adenocarcinoma in situ), 10 benign samples, and 45 NL tissues. For the untargeted metabolomics technique, 25 LUAD samples were assigned as the case group and 30 NL tissues as the control group. For the targeted metabolomics technique, ten LUAD samples were assigned as the case group and 15 NL tissues as the control group. Samples were analyzed by untargeted and targeted metabolomics, with liquid chromatography-tandem mass spectrometry detection used as part of the experimental procedure.Untargeted metabolomics revealed 164 differential metabolites between the case and control groups, comprising 110 up regulations and 54 down regulations. The main metabolic differences found by the untargeted method were organic acids and their derivatives. Targeted metabolomics revealed 77 differential metabolites between the case and control groups, comprising 69 up regulations and eight down regulations. The main metabolic changes found by the targeted method were fatty acids, amino acids, and organic acids. The levels of organic acids such as lactic acid, fumaric acid, and malic acid were significantly increased in LUAD tissue compared to NL. Specifically, an increased level of L-lactic acid was found by both untargeted (variable importance in projection [VIP] = 1.332, fold-change [FC] = 1.678, q = 0.000) and targeted metabolomics (VIP = 1.240, FC = 1.451, q = 0.043). Targeted metabolomics also revealed increased levels of fumaric acid (VIP = 1.481, FC = 1.764, q = 0.106) and L-malic acid (VIP = 1.376, FC = 1.562, q = 0.012). Most of the 20 differential fatty acids identified were downregulated, including dodecanoic acid (VIP = 1.416, FC = 0.378, q = 0.043) and tridecane acid (VIP = 0.880, FC = 0.780, q = 0.106). Furthermore, increased levels of differential amino acids were found in LUAD samples.Lung cancer is a complex and heterogeneous disease with diverse genetic alterations. The study of metabolic profiles is a promising research field in this cancer type. Targeted and untargeted metabolomics revealed significant differences in metabolites between LUAD and NL tissues, including e
本研究旨在利用代谢组学技术鉴定肺腺癌(LUAD)组织与正常肺(NL)组织之间的差异代谢物和关键代谢通路,从而发现肺癌早期诊断的潜在生物标志物。研究招募了45名经计算机断层扫描成像确定的原发性磨玻璃结节(GGN)患者,这些患者愿意在2021年12月至2022年12月期间在上海总医院接受手术治疗。所有参与者均接受了视频胸腔镜手术,并进行了肺段或楔形切除。病理检查的组织样本取自磨玻璃结节(GGN)病变部位和距离病变3厘米处(NL)。病理结果为 35 例肺腺癌(LUAD)(13 例浸润性腺癌、14 例微小浸润性腺癌和 8 例原位腺癌)、10 例良性样本和 45 例 NL 组织。在非靶向代谢组学技术中,25 个 LUAD 样本被指定为病例组,30 个 NL 组织被指定为对照组。对于靶向代谢组学技术,10 个 LUAD 样本被指定为病例组,15 个 NL 组织被指定为对照组。样本通过非靶向和靶向代谢组学进行分析,实验过程中使用了液相色谱-串联质谱检测。非靶向代谢组学发现病例组和对照组之间存在 164 种不同的代谢物,包括 110 种上调代谢物和 54 种下调代谢物。非靶向方法发现的主要代谢差异是有机酸及其衍生物。靶向代谢组学发现病例组和对照组之间存在 77 种不同的代谢物,其中 69 种向上调节,8 种向下调节。靶向方法发现的主要代谢变化是脂肪酸、氨基酸和有机酸。与 NL 相比,LUAD 组织中乳酸、富马酸和苹果酸等有机酸的含量明显增加。具体来说,非靶向(预测中的可变重要性[VIP] = 1.332,折变[FC] = 1.678,q = 0.000)和靶向代谢组学(VIP = 1.240,FC = 1.451,q = 0.043)均发现 L-乳酸的含量增加。靶向代谢组学还发现富马酸(VIP = 1.481,FC = 1.764,q = 0.106)和 L-苹果酸(VIP = 1.376,FC = 1.562,q = 0.012)的含量增加。在已确定的 20 种差异脂肪酸中,大部分都出现了下调,包括十二烷酸(VIP = 1.416,FC = 0.378,q = 0.043)和十三烷酸(VIP = 0.880,FC = 0.780,q = 0.106)。此外,在 LUAD 样本中还发现了差异氨基酸水平的升高。肺癌是一种复杂的异质性疾病,具有多种多样的基因改变。对这种癌症类型进行代谢谱研究是一个很有前景的研究领域。靶向和非靶向代谢组学揭示了LUAD和NL组织代谢物的显著差异,包括有机酸水平升高、脂肪酸水平降低和氨基酸水平升高。这些代谢特征为了解LUAD的发病机制提供了宝贵的信息,并有可能成为预后和治疗反应的生物标志物。

Knowledge of proper collection, storage, preservation, and processing techniques is critical to ensuring proper handling and analysis of fluid cytology specimens. This study was conducted to determine the effect of anticoagulation, pre-smearing acetic acid treatment technique, and saline rehydration technique on morphological assessment, reproducibility, and reporting in fluid cytology.The study was carried out in the cytopathology laboratory over 2 months (April–May 2022), where 100 effusion samples were analyzed. At least 20–40 mL of fluid was collected in heparinized and non-heparinized containers for each patient. Samples were processed in cytospin and stained with Giemsa and Papanicolaou stains. For 70 hemorrhagic specimens, an extra smear was prepared from the sediment and subjected to the saline rehydration technique as per the Indian Academy of Cytologists (IAC) guidelines. Seventy-three hemorrhagic specimens whose quantity received was more than 35 mL were subjected to the pre-smearing technique. These smears were evaluated for (a) the presence or absence of blue background/any other background staining, (b) cellularity, (c) cell morphology and (d) the presence/absence of microclots.Heparinized samples showed no compromise in cellular morphology or cellularity although a blue background was observed in an occasional case. The pre-smearing technique had less background hemorrhage and preserved cell characteristics. The post-smearing saline rehydration technique did not compromise the cellularity but distorted morphology and showed background staining.The pre-smearing acetic acid treatment showed better-preserved cellularity and cytomorphology with the absence of background staining when compared to the post-smearing saline rehydration technique.
掌握正确的采集、储存、保存和处理技术对于确保正确处理和分析体液细胞学标本至关重要。本研究旨在确定抗凝、涂片前醋酸处理技术和生理盐水补液技术对体液细胞学形态学评估、可重复性和报告的影响。研究在细胞病理学实验室进行,历时两个月(2022 年 4 月至 5 月),共分析了 100 份流出液样本。每名患者至少用肝素化和非肝素化容器收集 20-40 毫升液体。样本经细胞载玻片处理,并用吉氏和巴氏染色法染色。对于 70 例出血性标本,根据印度细胞学家学会(IAC)的指导原则,从沉淀物中制备额外的涂片,并进行生理盐水补液技术处理。73 份出血标本的样本量超过 35 毫升,则采用预涂片技术。对这些涂片进行了以下方面的评估:(a) 是否存在蓝色背景/任何其他背景染色;(b) 细胞性;(c) 细胞形态;(d) 是否存在微凝块。涂片前技术的背景出血较少,并保留了细胞特征。与涂片后生理盐水补液技术相比,涂片前醋酸处理技术能更好地保存细胞和细胞形态,且无背景染色。

Atypical squamous cells of undetermined significance cytology (ASC-US) is a challenging and equivocal diagnosis for pathologists in cervical Pap smears. The data on ASC-US cervical cytology in Bahrain are deficient. This study reviewed and identified the reporting rates, high-risk human papillomavirus (HPV) testing results, histopathologic follow-up findings, and the cytologic progression of patients diagnosed with ASC-US in Bahrain.A retrospective chart review was conducted on the medical records of 23,888 women who had Pap smear test results between January 2019 and March 2022 at the main referral tertiary hospital in Bahrain to identify the ASC-US cases. High-risk HPV (hrHPV) genotype was identified, and the histopathological results of the cervical biopsy was recorded. In addition, cytologic follow-up Pap smear tests conducted within 1 year of ASC-US diagnosis were tracked to monitor the progression or regression of ASC-US.In this study, 259 out of 23,888 women reported to have ASC-UC cytology results with a reporting rate of 1.1%. The mean age of the ASC-US cases was 43 ± 11.6. Thirty percent of the ASC-US cases tested positive for hrHPV, and they were predominantly infected with the other hrHPV genotype (75%). When the histopathological changes of the cervix were analyzed, 82.1% had normal histopathologic findings. However, low-grade cervical intraepithelial neoplasia-1 was reported in 2 cases (7.1%), and high-grade cervical lesions (cervical intraepithelial neoplasia-2 and higher) were reported in 3 cases (10.7%). Regarding the cytologic follow-up, most of the ASC-US cases were negative for intraepithelial lesion or malignancy (NILM) (73.8%) or had persistent ASC-US (17.9%). The remaining minority of cases progressed into either low-grade squamous intraepithelial lesions (6%) or high-grade squamous intraepithelial lesions (2.4%). There was a statistically significant and relatively strong association between the cytology follow-up findings and the hrHPV test results (χ2 [2] = 8.869, P < 0.012, Cramer’s V = 0.417).This is the first and largest study to characterize the ASC-US cytology cases in Bahrain. The reporting rates of ASC-US fell within the worldwide reported range. Although most of the ASC-US cases regressed into NILM, ASC-US showed progression into more advanced cervical cytologic diagnoses or contributed to the malignant transformation of cervical tissue, especially in the presence of hrHPV infection which was positive in 30% of the ASC-US cases. This emphasizes the role of cotesting (combination of hrHPV genotyping and Pap smear test) and the importance of colposcopic evaluation of those women with cytologic follow-up tests at 1 year of diagnosis. Implementing these recommendations in the cervical cancer screening practice in Bahrain will help in having a better management plan for women diagnosed with ASC-US cervical cytology.
意义未定的非典型鳞状细胞细胞学检查(ASC-US)是病理学家在宫颈巴氏涂片检查中面临的一项具有挑战性且模棱两可的诊断。巴林有关 ASC-US 宫颈细胞学检查的数据尚不充分。本研究回顾并确定了巴林ASC-US患者的报告率、高危人乳头瘤病毒(HPV)检测结果、组织病理学随访结果以及细胞学进展情况。研究人员对巴林主要转诊三级医院2019年1月至2022年3月期间23888名接受巴氏涂片检测的女性病历进行了回顾性病历审查,以确定ASC-US病例。确定了高危 HPV(hrHPV)基因型,并记录了宫颈活检的组织病理学结果。此外,还对 ASC-US 诊断后 1 年内进行的细胞学后续巴氏涂片检查进行了跟踪,以监测 ASC-US 的进展或消退情况。在这项研究中,23888 名妇女中有 259 人报告了 ASC-UC 细胞学结果,报告率为 1.1%。ASC-US病例的平均年龄为43 ± 11.6岁。30%的ASC-US病例hrHPV检测呈阳性,她们主要感染了另一种hrHPV基因型(75%)。在对宫颈组织病理学变化进行分析时,82.1%的病例组织病理学结果正常。但有 2 例(7.1%)报告了低级别宫颈上皮内瘤变-1,3 例(10.7%)报告了高级别宫颈病变(宫颈上皮内瘤变-2 及更高)。在细胞学随访方面,大多数 ASC-US 病例上皮内病变或恶性肿瘤(NILM)阴性(73.8%)或 ASC-US 持续存在(17.9%)。其余少数病例进展为低级别鳞状上皮内病变(6%)或高级别鳞状上皮内病变(2.4%)。细胞学随访结果与 hrHPV 检测结果之间存在统计学意义上的显著关联(χ2 [2] = 8.869,P < 0.012,Cramer's V = 0.417)。ASC-US的报告率在全球报告范围内。尽管大多数 ASC-US 病例都转为 NILM,但 ASC-US 仍会发展为更晚期的宫颈细胞学诊断,或导致宫颈组织恶变,尤其是在存在 hrHPV 感染的情况下,30% 的 ASC-US 病例中 hrHPV 呈阳性。这就强调了联合检测(hrHPV 基因分型与巴氏涂片检测的结合)的作用,以及对那些在确诊后 1 年进行细胞学随访检测的妇女进行阴道镜评估的重要性。在巴林的宫颈癌筛查实践中实施这些建议将有助于为确诊为 ASC-US 宫颈细胞学检查的妇女制定更好的管理计划。

Although most of the ASC-US cases regressed into NILM, ASC-US showed progression into more advanced cervical cytologic diagnoses or contributed to the malignant transformation of cervical tissue, especially in the presence of hrHPV infection which was positive in 30% of the ASC-US cases. This emphasizes the role of cotesting (combination of hrHPV genotyping and Pap smear test) and the importance of colposcopic evaluation of those women with cytologic follow-up tests at 1 year of diagnosis. Implementing these recommendations in the cervical cancer screening practice in Bahrain will help in having a better management plan for women diagnosed with ASC-US cervical cytology.\u0000","PeriodicalId":49082,"journal":{"name":"Cytojournal","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140232261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adenoid cystic carcinomas (ADCC) are distinctive salivary gland neoplasms with characteristic histomorphology. The diagnosis of dedifferentiation/high-grade transformation (HGT) indicates poor prognosis and is most often made on histopathology. We present a case of ADCC arising from a minor salivary gland tumor exhibiting HGT, reaching up to the submandibular gland and having lymph node metastases, suspected on fine-needle aspiration cytology. The index case highlights the awareness of the entity of the HGT of salivary gland tumors and raises suspicion for cytological diagnosis.
腺样囊性癌(ADCC)是具有特征性组织形态的独特唾液腺肿瘤。脱分化/高级别转化(HGT)的诊断预示着不良预后,通常是通过组织病理学做出的。我们介绍了一例ADCC病例,该病例是由一个表现为HGT的小唾液腺肿瘤引起的,肿瘤已达颌下腺,并有淋巴结转移,细针穿刺细胞学检查怀疑该肿瘤有淋巴结转移。该病例突出了人们对唾液腺肿瘤 HGT 实体的认识,并提高了对细胞学诊断的怀疑。

In an era of minimally invasive and rapid diagnostic technologies, fine-needle aspiration cytology (FNAC) is most useful when it comes to patients with lymphadenopathies especially of the cervical region. Liquid-based cytology (LBC) is an alternative processing method which is used for both gynecological and non-gynecological samples. Because of the remarkable advantages of LBC smears in gynecological samples, nowadays, many studies have been done to assess its utility in various other lesions. Hereby, with the help of this study, we would like to evaluate the efficiency of LBC smears in comparison to conventional FNAC smears conventional smears (CS) on lymph node aspirates.A retrospective study was done over a 1-year period in which 253 cases of lymph node aspirates were included in the study. The slides were prepared using standard conventional and LBC techniques and compared for adequacy, cellularity, cell architecture, necrosis, background debris, presence of cells in monolayer sheets, and nuclear/cytoplasmic details.Of the total 253 cases, 171 (67.6%) were and 67 (26.5%) were diagnosed as non-neoplastic and malignant, respectively. Although the LBC smears were useful in the diagnosis of malignant cases, they did pose some challenges especially in the non-neoplastic lymph node aspirates due to loss of the background necrosis. In addition, the cellular yield in LBC smears was low in comparison to CS.LBC smears from lymph node aspirates results in better diagnostic accuracy for malignant cases due to better cellular and nuclear details. However, for non-neoplastic etiology, it should not be considered better than CS as loss of the background necrosis and inflammation may result in an incorrect diagnosis.
在采用微创和快速诊断技术的时代,细针穿刺细胞学检查(FNAC)对淋巴腺疾病(尤其是宫颈淋巴腺疾病)患者最为有用。液基细胞学(LBC)是另一种处理方法,可用于妇科和非妇科样本。由于液基细胞涂片在妇科样本中的显著优势,如今已有许多研究对其在其他各种病变中的实用性进行了评估。在本研究的帮助下,我们希望评估 LBC 涂片与常规 FNAC 涂片、常规涂片(CS)在淋巴结抽吸物中的应用效果。这项回顾性研究历时 1 年,共纳入了 253 例淋巴结抽吸样本,采用标准的常规和 LBC 技术制备切片,并对切片的充分性、细胞性、细胞结构、坏死、背景碎屑、单层片状细胞的存在以及核/胞质细节进行比较。虽然 LBC 涂片有助于诊断恶性病例,但也带来了一些挑战,尤其是在非肿瘤性淋巴结穿刺中,因为背景坏死消失了。此外,与 CS 相比,LBC 涂片的细胞产量较低。淋巴结抽吸物的 LBC 涂片对恶性病例的诊断准确性更高,因为细胞和核的细节更清晰。然而,对于非肿瘤性病因,LBC涂片并不比CS更好,因为失去了坏死和炎症的背景可能会导致诊断错误。

Thoracocentesis is a less invasive and expensive procedure than pleural biopsy, enabling sample collection for cytological evaluation. Cell blocks prepared from these samples provide histopathological diagnoses; further, immunohistochemistry (IHC) can be performed for subtyping malignancies, guiding the clinician in choosing the appropriate treatment modality for the patient. We aimed to determine the various histological subtypes of malignancies using cell block IHC and compare the cell block and conventional cytology methods for diagnosing malignant pleural effusion.All pleural fluid samples from the clinically suspicious cases of malignancy collected at the Department of Pathology, Government Medical College Kottayam, India, during 18 months, except duplicate and inadequate samples, were included in this prospective observational study. IHC was performed on cell blocks that were positive for malignancy.This study analyzed 630 samples, of which 121 cell blocks demonstrated the presence of malignancy. Overall, 80%, 13%, and 7% of cases were negative, suspicious, and positive for malignancy based on conventional cytology, and 81%, 0%, and 19% were negative, suspicious, and positive for malignancy based on cell blocks, respectively. Among all malignancies, adenocarcinomas from the lung (56%) were the most common, followed by adenocarcinomas from the breast (6%), squamous cell carcinomas (5%), and adenocarcinomas from the ovary (3%). Cell blocks helped detect more malignancies (19%) than conventional cytology (7%), despite a moderate agreement between both methods.Adenocarcinomas were the most common cause of malignant pleural effusions, and the most frequent site of origin was the lungs. Cell blocks helped diagnose more malignancies than conventional cytology.

Objective: The most important determinant of patient outcome in cases of breast carcinoma is the regional lymph node status. Intraoperative assessment of sentinel lymph nodes (SLNs) allows the surgeon to perform axillary lymph node dissection in the same sitting if required. The commonly performed intraoperative methods for SLN evaluation are touch imprint cytology (TIC) and frozen section. The present study aimed to determine the sensitivity, specificity, and accuracy of TIC with histopathological diagnosis as gold standard.

Material and methods: The lymph nodes sent for intraoperative examination were bisected along the long axis and touched onto clean glass slides followed by Toluidine blue and rapid Papanicolaou staining. The imprints were reviewed and the interpretation was conveyed to the surgeon. Thereafter, the biopsy was fixed in 10% formalin followed by paraffin embedding with hematoxylin and eosin staining. The specificity, sensitivity, diagnostic accuracy, positive predictive value, and negative predictive value were evaluated with histopathological diagnosis as gold standard.

Results: A total of 60 patients who underwent resection surgery were included in the study. Majority (36.7%) of patients were in the age group 41-50 years with a mean age of 48.1 ± 10.6 years. There were 54 cases (90%) and 6 cases (10%) of invasive carcinoma of no special type (ductal) and lobular carcinoma, respectively. According to modified Bloom-Richardson scoring, the cases were categorized as Grade 1-6 cases (10%), Grade 2-36 (60%), and Grade 3-18 (30%). The sensitivity and specificity of TIC were 87.5% and 100%, respectively. The diagnostic accuracy of TIC in the diagnosis of metastasis in SLN was 90%.

Conclusion: TIC is an easy-to-perform, cost-effective, rapid, and accurate technique for axillary lymph node evaluation, which also overcomes the need for a cryostat.

目的:乳腺癌患者的预后最重要的决定因素是区域淋巴结状态。对前哨淋巴结(SLN)进行术中评估可使外科医生在必要时在同一坐位进行腋窝淋巴结清扫。术中评估前哨淋巴结的常用方法是触摸印迹细胞学(TIC)和冰冻切片。本研究旨在确定以组织病理学诊断为金标准的 TIC 的敏感性、特异性和准确性:将送去进行术中检查的淋巴结沿长轴一分为二,触及干净的玻璃载玻片,然后进行甲苯胺蓝和快速巴氏染色。对印记进行复核,并将解释传达给外科医生。之后,将活检组织固定在 10%福尔马林中,再用石蜡包埋,苏木精和伊红染色。以组织病理学诊断为金标准,对特异性、敏感性、诊断准确性、阳性预测值和阴性预测值进行了评估:研究共纳入了 60 名接受切除手术的患者。大多数患者(36.7%)的年龄在 41-50 岁之间,平均年龄为(48.1 ± 10.6)岁。无特殊类型的浸润性癌(导管癌)和小叶癌分别有 54 例(90%)和 6 例(10%)。根据改良布卢姆-理查德森评分法,病例分为 1-6 级(10%)、2-36 级(60%)和 3-18 级(30%)。TIC 的敏感性和特异性分别为 87.5%和 100%。TIC诊断SLN转移的准确率为90%:结论:TIC 是一种操作简便、经济高效、快速准确的腋窝淋巴结评估技术,而且无需使用低温恒温器。

Intraoperative assessment of sentinel lymph nodes (SLNs) allows the surgeon to perform axillary lymph node dissection in the same sitting if required. The commonly performed intraoperative methods for SLN evaluation are touch imprint cytology (TIC) and frozen section. The present study aimed to determine the sensitivity, specificity, and accuracy of TIC with histopathological diagnosis as gold standard.</p><p><strong>Material and methods: </strong>The lymph nodes sent for intraoperative examination were bisected along the long axis and touched onto clean glass slides followed by Toluidine blue and rapid Papanicolaou staining. The imprints were reviewed and the interpretation was conveyed to the surgeon. Thereafter, the biopsy was fixed in 10% formalin followed by paraffin embedding with hematoxylin and eosin staining.
