Abstract

Introduction: The Milan System for reporting salivary gland cytopathology helps standardize reporting systems across institutions, improve communication between clinicians and pathologists and guide the clinical management of patients.

Aims: This study was undertaken to evaluate the utility of the Milan system classification in cytology reporting.

Settings and design: The present study is a retrospective study conducted over a period of five years in tertiary care centre.

Methods and materials: All the cases of salivary gland aspirates were reviewed and reclassified into six diagnostic categories according to the Milan system of reporting salivary gland cytology (MSRSGC). Cytological diagnosis was correlated with the histopathological diagnosis wherever available.

Results: A total of 258 cases were classified using the Milan system as non-diagnostic (20.9%), non-neoplastic (26.3%), atypia of undetermined significance (4.7%), neoplasm benign (37.5%), neoplasm of uncertain malignant potential (3.5%), suspicious for malignancy (0.4%), and malignancy (6.6%). Cytohistological discordance was noted among 8/76 cases (10.5%). The sensitivity and specificity of FNAC were 75% and 98.5%, respectively. The risk of malignancy was 14.2% for Category I, 9% for II, 50% for III, zero for IVA and IVB, and 83.3% for category VI.

Conclusions: The new classification system helps pathologists to standardize reporting leading to better clinical and surgical management.

基于“唾液腺细胞学报告米兰系统”的唾液腺抽吸物重新分类:一项为期五年的回顾性研究。

简介:唾液腺细胞病理学报告米兰系统有助于标准化跨机构的报告系统，改善临床医生和病理学家之间的沟通，指导患者的临床管理。目的:本研究旨在评估米兰系统分类在细胞学报告中的效用。背景和设计:本研究是一项回顾性研究，在三级保健中心进行了五年的研究。方法与材料:对所有涎腺抽吸病例进行回顾性分析，并根据milansystem of reporting salivary gland cytology (MSRSGC)重新分类为6种诊断类型。细胞学诊断与组织病理学诊断有相关性。结果:258例患者采用米兰标准分为:非诊断性(20.9%)、非肿瘤性(26.3%)、意义不明的异型性(4.7%)、良性肿瘤(37.5%)、恶性潜能不确定的肿瘤(3.5%)、可疑恶性肿瘤(0.4%)、恶性肿瘤(6.6%)。76例患者中有8例(10.5%)存在细胞组织学差异。FNAC的敏感性为75%，特异性为98.5%。ⅰ类肿瘤的恶性风险为14.2%，ⅱ类为9%，ⅲ类为50%，IVA和IVB为零，ⅵ类为83.3%。结论:新的分类系统有助于病理学家规范报告，从而改善临床和手术处理。

期刊介绍： The Journal of Cytology is the official Quarterly publication of the Indian Academy of Cytologists. It is in the 25th year of publication in the year 2008. The journal covers all aspects of diagnostic cytology, including fine needle aspiration cytology, gynecological and non-gynecological cytology. Articles on ancillary techniques, like cytochemistry, immunocytochemistry, electron microscopy, molecular cytopathology, as applied to cytological material are also welcome. The journal gives preference to clinically oriented studies over experimental and animal studies. The Journal would publish peer-reviewed original research papers, case reports, systematic reviews, meta-analysis, and debates.
