作者观察喉癌及喉咽部癌切除标本的外形及组织病理学,希能发现某些病变的发生率及病变扩展与手术后存活率的影响,以便选择治疗方法,并了解这种疾病的确实预后。本文的喉癌分期和分类与国际及美国(AJC及UICC)专科会议所建泌者相同,但作了小修改。声门癌向声门下扩展大于10毫米者,划入T_3类;声门癌侵及两侧声带者,仍划为T_2,或更进一级,但不用T_(1b)类。喉咽部分成四区:上喉咽部、下喉咽部、后喉咽部及环状软骨后区。上喉咽部:后界为会厌舌面,下为会厌谷,
The authors observed the appearance and histopathology of resection specimens of laryngeal cancer and laryngeal cancer, and hoped to find the incidence of certain diseases and the influence of the disease expansion and the survival rate after surgery in order to select the treatment method and understand the facts of the disease. Prognosis. The staging and classification of laryngeal cancer in this article are the same as those established by the International and American (AJC and UICC) Specialized Conferences, but with minor modifications. Glottic cancer more than 10 mm below the subglottic extension, into the T_3 category; glottic cancer invasion and bilateral vocal cords, still classified as T_2, or further level, but not T_ (1b) category. The hypopharynx is divided into four regions: the upper throat, the lower throat, the posterior hypopharynx, and the posterior cricoid cartilage. Upper throat: The posterior border is the epiglottis tongue, and the lower epiglottis valley.
