[Guideline on pathological diagnosis of oral and oropharyngeal squamous cell carcinoma].

Oral and oropharyngeal squamous cell carcinomas are the most common malignant tumours of the oral and maxillofacial region. A standardized pathological diagnosis report for oral and oropharyngeal squamous cell carcinoma should provide not only the pathological diagnosis itself as much accurate as possible, but also the information related to assessment of prognosis and strategy of treatment for the patient. An expert group organized by Society of Oral Pathology, Chinese Stomatological Association has set a guideline for the tissue fixation, gross examination and format of the pathological diagnosis report of oral and oropharyngeal squamous cell carcinoma. The guideline covers the important changes in clinical and pathological aspects of oral and oropharyngeal squamous cell carcinomas in recent years, such as depth of invasion in T category, extranodal extension in N category and human papilloma virus-associated squamous cell carcinoma in oropharyngeal carcinomas. Hopefully the guideline will improve the quality of pathological reports of oral and oropharyngeal squamous cell carcinomas and provide reliable data on clinical therapy and prognosis evaluation of patients with oral and oropharyngeal squamous cell carcinomas in China.口腔癌及口咽癌是口腔颌面部最常见的恶性肿瘤。规范化的口腔癌及口咽癌病理诊断报告不仅应提供给临床准确的病理诊断，还应包括与患者预后评估、治疗策略选择相关的信息。由中华口腔医学会口腔病理学专业委员会牵头组织成立专家组，对口腔癌及口咽癌病理标本固定、取材及报告内容等进行研讨与规范，形成《口腔癌及口咽癌病理诊断规范》。此规范涵盖了近年来在口腔癌和口咽癌临床病理方面的一些重要变化，如口腔癌肿瘤T分期应考虑肿瘤侵袭深度、肿瘤N分期应考虑有无淋巴结外扩展、口咽癌中新亚型人乳头状瘤病毒相关性鳞状细胞癌等。希望通过本规范的制定，提高我国口腔癌及口咽癌病理报告质量，为临床治疗及预后评估提供依据。.
