声门下扩展癌近年有增加之势,且一次治疗后易复发,对复发癌二次治疗极困难,故研究其特性,从中寻求一次治疗的指针。作者等22年中治疗415例喉癌、追踪400例,其中声门下癌20例,声门上癌向声门下进展者4例,声门癌向声门下扩展者36例,共60例,年龄高峰为60岁,男女比为29∶1。60例资料统计:初发症状主要为声嘶(95%),其次为呼吸困难和喘鸣(51.7%),血痰1例。上述症状提示声门下癌或声门下扩展癌之可能。紧急气管切开18例(30%),切开部位均为第4气管环以上造口。60例初诊病人中有颈淋巴结转移者21例(35%),主要位于喉前、气管旁及下颈深淋巴结,20例声门下癌有10例淋
Subglottic carcinoma has increased in recent years, and it is prone to relapse after a single treatment. It is extremely difficult to re-treat cancer with secondary treatments. Therefore, study its characteristics and seek a guideline for treatment. The authors treated 415 cases of laryngeal carcinoma and tracked 400 cases in 22 years, including 20 cases of subglottic carcinoma, 4 cases of supraglottic carcinoma progression to subglottic aperture, and 36 cases of glottic carcinoma extending to subglottic aperture. Altogether, there were 60 cases. The peak was 60 years, and the ratio of male to female was 29:1. Statistics of 60 cases: The initial symptoms were mainly hoarseness (95%), followed by dyspnea and wheezing (51.7%), and one case of blood stasis. The above symptoms suggest the possibility of subglottic cancer or subglottic cancer. Emergency tracheotomy was performed in 18 cases (30%), and the incision sites were all above the fourth tracheal ring. Among the 60 newly diagnosed patients, there were 21 cases (35%) with cervical lymph node metastases, mainly located in the prelaryngeal, paratracheal, and deep cervical lymph nodes. There were 20 cases of subglottic cancer in 10 cases.
