原发灶不明颈部淋巴结转移癌的诊断与综合治疗

Diagnosis and combined modality treatment of cervical lymph node metastasis from an unknown primary

原发灶不明颈部淋巴结转移癌并不少见，但至今未建立起必要的诊断程序。对于不明原发灶患者的综合治疗方法主要包括放射治疗和手术治疗，但始终存在争议。正电子发射断层显像（PET）以及分子生物学的发展提高了诊断的精确性，综合治疗的模式有了一定进展。

Cervical metastasis carcinoma of unknown primary is not uncommon. No established concept exists for the necessary procedures of diagnosis. The combined modality therapy for patients in whom no primary tumor is found includes surgery and radiotherapy, but there is still controversy. The development of PET and molecular biology enhances the accuracy of diagnosis. The pattern of combined modality therapy is now in progress.
