为确立一种原发喉室的跨声门癌，选择肿瘤主体以喉室为中心经全喉切除手术的标本５０例，火棉胶包埋，连续切片观察。结果发现①跨声门癌的肿瘤原发部位在喉室，５０例中有Ｔ２３例。②肿瘤以深层浸润为主占９０％（４５／５０），易侵及声门旁间隙（８２％，４１／５０）和甲状软骨（６４％，３２／５０），临床分期与病理分期不符达４８％（２４／５０）。结论：原发喉室的跨声门癌是声门上型癌的一种特殊类型。
In order to establish a primary glottic transglottic carcinoma, 50 cases with the main body of the tumor undergoing total laryngectomy with the larynx as the center were selected and embedded in collemblast, and were continuously sectioned for observation. The results showed that 1 primary site of transcranial cancer was in the larynx, and there were T23 cases in 50 cases. 2 90% (45/50) of the tumors were mainly infiltrates, and were easily invaded into the paraglottic space (82%, 41/50) and thyroid cartilage (64%, 32/50). Clinical staging and pathological staging did not match. 48% (24/50). Conclusion: Transglottic carcinoma of the primary larynx is a special type of supraglottic carcinoma.
