颈部肿物诊断不易,最终依靠组织学诊断。原发灶不明的颈淋巴结转移癌发现率高,耳鼻喉科也常见。作者就1964～1985年癌中心——新泻医院,原发灶不明颈部转移癌33例加以讨论。将治疗前未能发现原发部位者定名为原发灶不明癌。其发病率为2.7％,男多于女,多于发现颈部肿物3个月内就诊。明确原发部位的有6例(其中喉癌和颈段食管癌分别为颌下、颈上、中淋巴结转移,与1981年Batsakis所述转移至颈上深、锁骨上窝淋巴结不符)。病理大部分为鳞状上皮癌和未分化癌。治疗以全摘、颈廓清术、放疗、化疗等方法并用或单用。作者认为淋巴结可因慢性炎 The diagnosis of cervical tumors is difficult and ultimately depends on histological diagnosis. The discovery rate of cervical lymph node metastases with unknown primary lesions is high, and otolaryngology is also common. The author discussed the 33 cases of cervical metastatic carcinoma of primary origin in Cancer Center, Niigata Hospital from 1964 to 1985. The patients who failed to find the primary site before treatment were designated as primary tumors of unknown origin. The incidence rate was 2.7%, more men than women, more than found neck lesions within 3 months of treatment. 6 cases were identified as the primary site (laryngeal cancer and cervical esophageal cancer were submandibular, supra-cervical, and metastatic lymph nodes, respectively, which were inconsistent with metastasis to deep cervical supraclavicular lymph nodes as described by Batsakis in 1981). Most of the pathology is squamous cell carcinoma and undifferentiated carcinoma. The treatment was combined or used alone with methods such as total extraction, neck dissection, radiotherapy, and chemotherapy. The author believes that lymph nodes may be due to chronic inflammation
