手术切除淋巴结数和转移数对食管癌患者术后生存的影响

Effect of the Operation Excision Lymph Node Number and Transfer Number on Postoperative Survival of Patients with Esophageal Cancer

目的探讨手术切除淋巴结数目和转移数目对食管癌患者术后生存的影响。方法选取48例食管癌患者进行随访,了解其手术切除淋巴结的数目、转移的数目和生存情况,随访5年,评价手术切除淋巴结数目和转移数目对食管癌患者术后生存的影响。结果淋巴结切除数目和转移的数目对患者的2年、3年和5年的平均生存率影响的差异均有统计学意义(P<0.05),淋巴结切除的数量是食管癌患者术后生存质量的保护因素,淋巴结转移的数量是食管癌患者术后生存质量的危险因素。结论淋巴结转移是食管癌患者预后差的主要原因,而手术中切除淋巴结数量的增加可以增加患者的术后生存率。

Objective To investigate the effect of operation excision lymph node number and transfer number on postop -erative survival of patients with esophageal cancer .Methods Operation excision lymph node number ,transfer number and surviv-al of 48 patients with esophageal cancer were detected ,follow-up was 5 years,and the effect of operation excision lymph node number and transfer number on postoperative survival of patients with esophageal cancer was evaluated .Results The differences of effects of number of lymph nodes resection and transfer on 2-,3-and 5-survival rates were statistically significant (P<0.05), the number of lymph nodes resection were protective factors for quality of life in patients with esophageal cancer after operation , the number of metastatic lymph nodes were risk factors for quality of life in patients with esophageal cancer after operation .Con-clusion Lymph node metastasis is the main cause of poor prognosis in patients with esophageal cancer after operation ,and the increase of the lymph node number can increase the survival rate of patients with esophageal cancer after operation .
