目的探讨颈部原发不明转移癌的合理治疗方式。方法 回顾分析６８例颈部原发不明转移癌患者的临床资料。结果中上颈低分化转移癌最好的治疗方式是放疗，转移性鳞癌则采用手术后加放疗，转移性腺癌中的乳头状腺癌治疗应采用甲状腺癌联合根治术。其５年生存率分别为５０．０％（２／４）、６６．７（８／１２）和８５．７％（１２／１４）。锁骨上区转移癌尤其右侧者应力争手术切除，辅之以化疗。随访中有１５．２％颈部原发不明转移癌患者发现原发病灶。结论对颈部原发不明转移癌的治疗方式，应根据淋巴结的病理性质、部位、局部和全身情况进行综合考虑。
Objective To investigate the reasonable treatment of primary cervical cancer with unknown metastasis. Methods Retrospective analysis of 68 cases of primary neck cancer patients with unknown metastatic clinical data. Results The best treatment for upper cervical neck poorly differentiated metastatic carcinoma was radiotherapy, while metastatic squamous cell carcinoma was treated with radiotherapy and radiotherapy after surgery. The treatment of papillary adenocarcinoma in metastatic adenocarcinoma should be combined with radical mastectomy for thyroid cancer. The 5-year survival rates were 50.0% (2/4), 66.7 (8/12) and 85.7% (12/14), respectively. Clavicular metastases, especially the right side of the area should strive for surgical resection, supplemented by chemotherapy. During the follow-up, 15.2% of patients with primary unidentified neck metastases found primary lesions. Conclusion The treatment of primary unidentified metastatic carcinoma of the neck should be comprehensively considered according to the pathological features, location, local and systemic conditions of lymph nodes.
