许多研究表明精确的解剖描述与肿瘤的临床表现并不一致。该研究有两个主要目的：首先，通过最近一组喉癌患者说明症状及并存疾病的分期对预后的重要性；其次，运用多变量统计学方法处理与预后相关的临床及形态学资料，制定一种新的分期系统，使预后的准确性比单纯的TNM分期有极 Many studies show that accurate anatomical descriptions and clinical manifestations of tumors are not consistent. This study has two main purposes: first, to demonstrate the importance of the prognosis for the symptoms and the stage of the coexistence of the disease in a recent group of laryngeal cancer patients; second, to develop multivariate statistical methods for clinical and morphological data related to the prognosis A new staging system that makes prognosis more accurate than simple TNM staging
