目的:探讨胸段食管癌术后淋巴结转移情况及其对患者5年生存期的影响。方法:对125例胸段食管癌患者的病例资料进行回顾性研究,统计其淋巴结转移情况以及转移度、转移数、转移域数等相关数据资料,并分析各种淋巴结转移情况对患者5年生存期的影响,再对基于不同淋巴结转移情况“手术组”与“手术+放疗组”的5年生存率进行比较。结果:有无淋巴结转移、淋巴结转移度、淋巴结转移数以及淋巴结转移域数均对胸段食管癌患者的5年生存率有显著影响(P<0.01);有淋巴结转移患者手术组的5年生存率显著低于手术+放疗组(P<0.01),同时术后加行放疗治疗对转移度>0、≤20%及转移数≥2枚的患者的5年生存率有显著影响(P<0.01)。结论:淋巴结转移是胸段食管癌患者术后效果的重要影响因素,淋巴结转移数0、1、及≥2枚的三级别分类或可更准确地反应胸段食管癌患者淋巴结转移数与5年生存率的关系;术后预防性放疗能提高有淋巴结转移、转移>0、≤20%及转移数≥2枚的患者的5年生存率。
Objective: To investigate the postoperative lymph node metastasis of thoracic esophageal cancer and its impact on the 5-year survival of patients. Methods: The clinical data of 125 patients with thoracic esophageal cancer were retrospectively studied. The data of lymph node metastasis, metastasis, metastasis and metastasis were analyzed retrospectively. The 5-year survival rate Period of impact, and then based on different lymph node metastases “surgery group ” and “surgery + radiotherapy group ” 5-year survival rates were compared. Results: The five-year survival rates of patients with thoracic esophageal cancer were significantly different (P <0.01), with or without lymph node metastasis, lymph node metastasis, lymph node metastasis and lymph node metastasis. The 5-year survival rate in patients with lymph node metastasis (P <0.01), and the postoperative radiotherapy had a significant effect on the 5-year survival rate of patients with metastasis degree> 0, ≤20% and number of metastasis≥2 (P <0.01) ). Conclusion: Lymph node metastasis is an important influencing factor for the postoperative outcome of patients with thoracic esophageal cancer. Lymph node metastasis number 0, 1, and ≥2 are three-level classification or can more accurately reflect the number of lymph node metastases in patients with thoracic esophageal cancer and 5 years Survival rate; postoperative radiotherapy can improve the 5-year survival rate of patients with lymph node metastasis, metastasis> 0, ≤ 20% and the number of metastases ≥ 2 pieces.
