胃癌淋巴结清扫数目与预后关系探讨

The relationship between the number of lymph node removed and the prognosis of gastric cancer

目的:探讨胃癌淋巴结清扫数目与预后的关系。方法:选取胃癌根治术清扫淋巴结数≥15枚的患者1443例,分为15~20枚、21~25枚、26~30枚、大于30枚四组。按照不同肿瘤部位、肿瘤大小、T分期、TNM分期,分别探讨淋巴结清扫数与生存期的相关性。结果:肿瘤≤5 cm并清扫26~30枚淋巴结组,胃体部肿瘤清扫21~25枚淋巴结组患者生存期均优于其余淋巴结组,组间比较差异有统计学意义(P<0.05)。结论:肿瘤≤5 cm清扫26~30枚淋巴结,胃体部肿瘤清扫21~25枚淋巴结组患者能延长生存期,清扫超过30枚淋巴结时,未见患者生存期明显增加。

Objective:To explore the relationship between the number of lymph node removed and the prognosis of gastric cancer.Methods:1443 gastric cancer patients with more than 15 lymph nodes removed were selected.They were divided into four groups:15-20,21-25,26-30 and more than 30.According to different tumor location,tumor size,T stage and TNM stage,the correlation between the number of lymph node removed and survival period was studied.Results:The survival time of the patients in the group of tumor≤5 cm and 26-30 lymph nodes removed,and 21-25 lymph nodes removed in gastric body tumor was better than that in the other groups.Conclusion:The remove of 26-30 lymph nodes in the group with tumor≤5 cm and 21-25 lymph nodes in the group with gastric body tumor can prolong the survival period.When more than 30 lymph nodes are removed,there is no significant increase in the survival period of patients.
