声门上癌的临床分期需对会厌前间隙(P-ES)估价。60％～80％的会厌癌侵犯 PES。PES的早期癌侵犯,物理检查难以确定,作者初步采用针吸活检法,并与 CT 扫描和喉连续切片比较。研究报告纽约大学医学中心1985年7月至1987年1月间16例未治疗的会厌鳞癌,男15名女1名,年龄48～68岁,按 AJC 分期,T_2 4、T_310、T_4 2。先行喉 CT 扫描,继行 PES 针吸活检,手术后对 PES 行组织病理切片共12例,其余4
The clinical stage of supraglottic cancer requires the evaluation of the pre-epiglotia (P-ES). 60% to 80% of epiglottis cancer invades PES. In the early stage of PES invasion of cancer, physical examination is difficult to determine. The author initially adopted aspiration biopsy method and compared with CT scan and serial laryngectomy. The study reported 16 cases of untreated epiglottis squamous cell carcinoma from July 1985 to January 1987 in New York University Medical Center. There were 15 males and 1 female, aged 48 to 68 years. According to the AJC staging, T_2 4, T_310, and T_42. CT scanning of the first larynx followed by PES needle biopsy. After operation, 12 cases of PES were histopathologically sectioned and the rest 4
