目的 探讨跨声门癌喉软骨支架受累的特点及意义。方法 选择临床喉全切除标本 50例 ,火棉胶包埋 ,连续切片观察。结果 跨声门癌喉软骨支架受累为 64% ( 32 / 50 ) ,其中单纯甲状软骨受累为 34 % ( 17/ 50 ) ,甲状软骨和环状软骨同时受累为 30 % ( 15/ 50 ) ;肿瘤早期就可浸润喉软骨支架 ;跨声门癌颈淋巴结转移率为 4 4 % ( 2 2 / 50 ) ,侵及与未侵及喉软骨支架者转移率分别为 56.2 5% ( 18/ 32 )、2 2 .2 2 % ( 4 / 18) ,二者差异显著 ( χ2 =4 .12 ,P <0 .0 5)。结论 充分认识跨声门癌喉软骨支架受累对临床诊断治疗具有重要指导意义。
Objective To investigate the characteristics and significance of laryngeal cartilage stenting involved in transglottic cancer. Methods Fifty cases of clinical specimens of total laryngectomy were selected. Results Thoracic cartilage stenting involved 64% (32/50) of the patients with transglottic cancer, of which simple thyroid cartilage involvement was 34% (17/50), thyroid cartilage and annular cartilage were 30% (15/50) The metastatic rate of cervical lymph nodes was 44% (2 2/50) in transantonic carcinoma, 56.2% (18/32) in invasive and non-invasive laryngeal cartilage and 22 .2 2% (4/18), the difference was significant (χ2 = 4.12, P <0.05). Conclusion It is of great importance to fully understand the involvement of laryngeal cartilage scaffold in transglottic cancer for clinical diagnosis and treatment.
