下咽癌侵犯喉结构的临床病理分析

THE CLINICAL AND HISTOPATHOLOGIC STUDY OF LARYNGAEL INVOLVEMENT OF HYPOPHARYNGEAL CARCINOMA

对 ２５ 例下咽癌的手术切除标本连续切片进行组织病理学研究，以探讨保留喉功能下咽癌手术的可行性。发现 Ｔ１ 、 Ｔ２ 病变很少累及喉结构，随 Ｔ 分级的升高，下咽癌侵犯喉结构的频度增加。下咽癌多累及部分喉组织，病变对侧的喉组织则常是正常的。因此，对于 Ｔ１、 Ｔ２ 病变及某些细心选择的 Ｔ３、 Ｔ４ 下咽癌，行保留喉功能手术不会影响下咽癌切除的彻底性，并能提高患者的生存质量。

Twenty five cases of hypopharyngeal carcinoma(HPC) specimens were subjected to a whole organ section study.The results showed that the laryngeal involvement of HPC has great regularity,that is T 1、T 2 lesions rarely invades the laryngeal structure.The frequency of laryngeal involvement rises with the increasing of T categorization.The controllateral larynx were usually free of tumor.Therefore,T 1、T 2 lesions of HPC can be eradicated with laryngeal function retained completely. To Some selected T 3、T 4lesions of HPC,they also can be eradicated with laryngeal function retained completely or partially,so improved the survival quality of the patients.
