血清癌胚抗原 (ＣＥＡ)作为肿瘤标记物 ,多见于结肠癌、乳腺癌等 ,其与喉癌的相关性研究鲜见报道。声门上型喉癌颈淋巴结转移率高 ,尤其对术前颈部触诊未见明显转移灶者 ,颈清扫术的时机选择是提高疗效的关键。本文采用单克隆抗体 放射免疫测定法对 5 7例声门上型喉癌患者进行 Serum carcinoembryonic antigen (CEA) as a tumor marker is more common in colon cancer, breast cancer, etc., and its correlation with laryngeal cancer is rarely reported. The rate of cervical lymph node metastasis in supraglottic laryngeal carcinoma is high, especially in patients with no significant metastases before palpation in the neck. The timing of neck dissection is the key to improve the curative effect. This article uses monoclonal antibody radioimmunoassay in 57 cases of supraglottic laryngeal carcinoma
