报告168例上颌窦癌临床分期和原发部位的研究方法和结果。对上颌窦的解剖区域划分、肿瘤原发部位的定位依据和方法及临床意义,临床分期标准及其与治疗、预后的关系进行了探讨。将上颌窦癌原发部位分成下区、上外区和上内区。下区癌占45.0％。上外区21.7％,上内区27.5％,未定5.8％。下区癌5年生存率较上区癌高3～6倍。使用TNM分期,制定了各期具体标准,Ⅱ期2例,Ⅲ期111例,Ⅳ期55例。术前对肿瘤的原发部位和病期作出诊断,对选择治疗方案、设计手术、估计预后等均具有重要参考价值。
Reported 168 cases of clinical staging and primary site of maxillary sinus cancer research methods and results. The classification of the anatomic region of the maxillary sinus, the location and method of the primary tumor location and its clinical significance, the clinical staging criteria and its relationship with treatment and prognosis were discussed. The primary site of maxillary sinus cancer was divided into the lower zone, the upper outer zone, and the upper inner zone. In the lower area, cancer accounted for 45.0%. 21.7% in the outer zone, 27.5% in the upper inner zone, and 5.8% undetermined. The 5-year survival rate of the lower area cancer is 3-6 times higher than that of the upper area cancer. Using TNM staging, the specific criteria for each phase were formulated, 2 in phase II, 111 in phase III, and 55 in phase IV. The preoperative diagnosis of the primary site and stage of the tumor is of important reference value in selecting the treatment plan, designing the operation, and estimating the prognosis.
