摘　　要：目的初步探讨HPV检测在诊断原发灶不明的颈淋巴结转移性鳞癌中的价值.方法收集复旦大学附属肿瘤医院6例首诊为原发灶不明的颈淋巴结转移性鳞癌,最终确诊为HPV相关口咽鳞癌,分析确诊过程.结果首诊时6例患者均被确诊为颈淋巴结转移性鳞癌,且p16表达阳性和HPV-16亚型阳性,而EBER表达阴性.经全面检查均未发现明显的原发病灶.随后对其中4例予同侧扁桃体盲检(2例)和切除(2例),病理均证实为扁桃体鳞癌.另2例分别在随访第149天、545天MRI检查发现同侧口咽侧壁和舌根增厚伴强化,经活检分别证实为扁桃体鳞癌、舌根鳞癌.结论对于原发灶不明的HPV阳性颈淋巴结转移性鳞癌,应高度怀疑原发病灶来源于口咽部位的可能性,特别是扁桃体和舌根部位.Objective To evaluate the diagnostic value of HPV detection in squamous cell carcinoma of the cervical lymph node metastasis from an unknown primary site.Methods Clinical data of 6 patients who were initially diagnosed with squamous cell carcinoma of the cervical lymph node metastasis from an unknown primary site and eventually diagnosed with HPV-related oropharyngeal squamous cell carcinoma were collected,and the process of diagnosis was analyzed.Results Upon the initial admission,all patients were diagnosed with squamous cell carcinoma of the cervical lymph node metastasis with positive p16 expression,positive HPV-16 subtype and negative EBER expression.No obvious primary lesion was found after comprehensive examination.Subsequently,four of them underwent ipsilateral tonsollar blind biopsy(n=2)and ipsilateral tonsillectomy(n=2).All these four patients were pathologically diagnosed with tonsillar squamous cell carcinoma.For the other two cases,MRI detected the thickening complicated with enhancement of ipsilateral wall of oropharynx and tongue root after follow-up for D149 and D545,respectively.Biopsy confirmed the diagnosis of squamous cell carcinoma of the tonsil and tongue root,respectively.Conclusion For patients with HPV-positive squamous cell carcinoma of the cervical lymph node metastasis from an unknown primary site,the possibility that the primary lesion originates from the oropharyngeal site,especially the tonsil and tongue root,should be highly suspected.
