国际细胞学学会联合国际癌症研究机构和世界卫生组织（WHO），制定报告肺、胰腺和胆道、淋巴结、软组织、肝脏、乳房、肾脏和肾上腺的细胞病理学的国际体系。WHO最近发布了肺和胰脏-胆道细胞病理学的报告系统。此合作的目标是规范细胞病理学的报告，通过确立实体和肿瘤的关键诊断细胞病理特征，改善报告质量；提供有关取样技术、标本处理和处理以及辅助技术使用等的详细最佳实践指南；并促进细胞病理学家和临床医生之间的沟通，以改善患者护理。每个WHO系统都定义了特定的分类和术语用于报告细胞病理学，每个分类在当前的文献允许的范围内估计了恶性风险，并提供了建议的诊断管理算法，以协助临床医生。WHO系统承认，地方医疗和病理基础设施会有所不同，特别是在低收入和中等收入国家，而且WHO系统及其诊断管理建议已经开发为允许在所有资源设置中全球应用。编辑和作者的选择、撰写和编辑责任的过程使用的是与第五版WHO Tumours分类相同的模型，该模型与WHO细胞病理学系统直接相关。本综述介绍了国际细胞学学会、国际癌症研究机构和WHO细胞病理学项目的合作理由和历史，以及肺部和胰脏-胆道细胞病理学的WHO报告系统的简要概述。© 2023 作者。由Wiley Periodicals LLC代表美国癌症协会出版的《癌细胞病理学》。

The International Academy of Cytology has joined with the International Agency for Research on Cancer and the World Health Organization (WHO) to develop international systems for reporting the cytopathology of lung, pancreas and biliary tract, lymph nodes, soft tissue, liver, breast, and kidney and adrenal gland. The WHO recently published the reporting systems for lung and pancreaticobiliary cytopathology. The objectives of this collaboration are to standardize the reporting of cytopathology; improve the quality of reporting by establishing the key diagnostic cytopathological features of entities and neoplasms; provide detailed best-practice guidelines in sampling techniques, specimen handling and processing, and the use of ancillary techniques; and facilitate communication between cytopathologists and clinicians to improve patient care. Each WHO system has defined specific categories and terminology for reporting cytopathology, and each category has an estimated risk of malignancy as far as the current literature allows and a suggested diagnostic management algorithm to assist clinicians. The WHO systems recognize that local medical and pathology infrastructure will vary, particularly in low-income and middle-income countries, and the WHO systems and their diagnostic management recommendations have been developed to allow them to be applied worldwide in all resource settings. The process of the selection of editors and authors and the writing and editing responsibilities has used the same model as that used for the fifth edition WHO Classification of Tumours, to which the WHO cytopathology systems are directly linked. This review provides the rationale and history of this joint International Academy of Cytology, International Agency for Research on Cancer, and WHO cytopathology project and a brief overview of the WHO reporting systems for lung and pancreaticobiliary cytopathology.© 2023 The Authors.
