食管癌是十分常见的恶性肿瘤,它的死亡率在我国占所有恶性肿瘤的23.5%.手术治疗仍是主要的治疗方法,但手术治疗分为根治切除及姑息性切除手术,还有一些病人仅能做开胸探查术.食管癌能否做到根治性切除取决于病变的局部外侵、病变的部位以及远处转移等情况.1 食管癌的分期目前国际通用的食管癌TNM分期标准以及我国拟定的食管癌病理分期标准分别见表1、2.对食管癌分期重要性在于它决定了病人的生存时间.肿瘤局限于食管壁比侵犯食管外膜,生存期会更长,前者五年生存率为40%,后者仅为4%左右;淋巴结的情况也很相似,淋巴结阴性者五年生存率为42%,阳性者仅为3%.
Esophageal cancer is a very common malignant tumor. Its mortality rate accounts for 23.5% of all malignant tumors in China. Surgical treatment is still the main treatment method, but surgical treatment is divided into radical resection and palliative resection, and some patients only Can do thoracotomy exploration. Esophageal cancer can do radical resection depends on the local invasion of lesions, lesions and distant metastasis and other conditions. 1 Esophageal cancer staging of the current international esophageal cancer TNM staging criteria and our country The proposed criteria for the staging of esophageal cancer are shown in Tables 1 and 2. The importance of staging of esophageal cancer is that it determines the patient’s survival time. The tumor is limited to the esophagus wall than the esophageal epithelium, the survival period will be longer, the former five years The survival rate is 40%, the latter is only about 4%; the situation of lymph nodes is also very similar, the five-year survival rate of lymph node negative is 42%, and the positive rate is only 3%.
