Therefore, we aimed to report VAINs detected in liquid-based cytology (LBC) from women examined at Hospital das Clínicas of Faculty of Medicine, Sao Paulo State University. Materials and Methods: We evaluated LBC samples from women referred to gynecology examination for different reasons (previous abnormal PapTest, follow up of treated cervical lesion, ecc) and women examined for regular screening proposals, and compared with biopsy diagnoses, including the controversial diagnoses of vaginal intraepithelial neoplasia (VAIN). Results: From 1866 patients, 1423 (76.3%) cases were negative and 443 (23.7%) were positive for any cellular alteration. Age of patients ranged from 12 to 86 years. We detected 25 histologically confirmed VAIN (1.3% p = 0.0002 by Fisher’s exact test IC 95% 0.0090 - 0.0198) and 1.1% VAIN (p = 0.0031 by Fisher’s exact test IC 95% 0.0077 - 0.0179). Conclusion: The identification of VAIN in routine is feasible;the professionals involved with cytological examination should be aware of these lesions in Pap test samples.展开更多
目的:脉络膜黑色素瘤(melanoma of choroid,CM)是成人常见的原发性眼内恶性肿瘤,特点为恶性程度高、易侵袭转移、预后极差,严重影响患者视力,甚至威胁患者生命。目前诊断CM主要依赖影像学检查,在眼球摘除手术后加做病理诊断,缺乏明确的...目的:脉络膜黑色素瘤(melanoma of choroid,CM)是成人常见的原发性眼内恶性肿瘤,特点为恶性程度高、易侵袭转移、预后极差,严重影响患者视力,甚至威胁患者生命。目前诊断CM主要依赖影像学检查,在眼球摘除手术后加做病理诊断,缺乏明确的术前病理诊断。本研究旨在探索液基细胞学涂片和细胞蜡块技术在CM术前诊断中的应用。方法:收集南京医科大学第一附属医院2023年3至6月收治的2例临床诊断为CM患者的脉络膜下液。采用液基细胞学涂片方法进行初步诊断,改良的细胞蜡块制作技术、苏木精-伊红(hematoxylin and eosin,HE)染色、脱黑色素和免疫组织化学(immunohistochemistry,IHC)染色进行进一步的病理诊断。结果:2例患者经过影像学检查均诊断为CM,通过液基细胞学涂片做出初步的细胞学病理诊断,1例诊断为“黑色素瘤”,另1例诊断为“见异型细胞,黑色素瘤不除外”。通过改良的细胞蜡块制作技术,HE、脱黑色素和IHC染色,病理诊断结果显示临床诊断相同的2例患者,1例明确诊断为CM,而另1例诊断为低分化神经内分泌癌,修正了原先的诊断。结论:本改良技术能够在手术前精准诊断CM,为临床眼科医生制定治疗方案提供重要依据,操作简便,值得推广。其有3个优点:1)能制作出10~20张连续切片,满足IHC染色的要求;2)在用本技术处理的切片中,可见各种异型细胞,且细胞核结构清晰;3)简单易行,成本不高,适用于各级医院,特别是中小医院。本文有2个原创点:1)将液基细胞学涂片、细胞蜡块切片及IHC染色用于诊断CM;2)对传统的细胞蜡块制作技术进行改良,使其适用于诊断CM。展开更多

文摘目的探讨在HPV阳性女性中,液基细胞学、DNA倍体分析及P16/Ki-67双染检测对宫颈癌前病变的分流作用。方法回顾性分析2021年5月至2022年12月在我院妇科行阴道镜及宫颈活检的妇女590例。患者高危人乳头瘤病毒(human papilloma virus,HPV)检测阳性,且行液基细胞学(liquid-based cytology,LBC)、DNA倍体分析、P16/Ki-67双染3种检查,对上述3种方法的灵敏度、特异性、受试者工作特征(receiver operating characteristic,ROC)曲线进行统计分析。结果液基细胞学、DNA倍体分析和P16/Ki-67双染3种筛查方法对宫颈癌前病变的灵敏度分别为84.2%、77.5%、76.4%,特异性分别为40.7%、49.2%、70.1%,曲线下面积(area under the curve,AUC)分别是0.625、0.634、0.733,其中,P16/Ki-67双染检测显著优于液基细胞学检查及DNA倍体分析(P<0.0001)。结论本研究认为,在HPV阳性女性中,P16/Ki-67双染检测的分流效果最佳。
