熟悉恶性肿瘤的分期,对制订治疗计划,检查治疗效果,估计预后都很重要。上颌窦癌已有许多分类法,本文对目前常用的六种方法作了比较,它们是:AJc、Rubin、Lederman、Sakai、GSH和Harrison法。上颌窦鳞癌53例,其中男20,女33,年龄36～95岁,所有病例均有完整的临床、X线摄片及手术记录,按上述分类法分别进行分期。根据AJC、Rubin、Lederman的上颌窦癌分期标准或肿瘤向每一方向侵犯的范围进行分期,不能满足起码的分期标准要求的肿瘤归入Tx组,根据临床和X线征及活检时发现估计肿瘤 Familiar with the staging of malignant tumors, the development of treatment plans, check the treatment effect, prognosis is very important. There are many classification of maxillary sinus cancer. In this paper, we compared six commonly used methods: AJc, Rubin, Lederman, Sakai, GSH and Harrison. Maxillary sinus squamous cell carcinoma in 53 cases, 20 males and 33 females, aged 36 to 95 years old, all cases have a complete clinical, X-ray and surgical records, according to the above classification were staged. According to AJC, Rubin, Lederman’s maxillary sinus cancer staging criteria or tumor invasion in each direction of the scope of staging can not meet the minimum staging requirements of the tumor classified as Tx group, based on clinical and X-ray findings and biopsy estimated tumor
