淋巴结状态在直肠癌外科治疗中的预后价值

Prognostic value of lymph node status in surgical treatment of rectal cancer

本文对１５９例直肠癌＂根治术＂病人进行了淋巴结分组统计学分析，按阳性淋巴结数分组：１～３阳性淋巴结组病人局部复发率较低２２％，术后５年生存率较高６０％，而＞３阳性淋巴结组病人则相反，局部复发率和术后５年生存率分别为４３％和３５％，二者差异非常显著；当以１～４和＞４阳性淋巴结分组时局部复发率并无明显差别，按我院淋巴结部位分组标准不能证明对术后局部复发和生存率有明显的统计学意义，因此，我们认为了解术后转移淋巴结数对于判断直肠癌外科治疗的预后有重要意义，且按１～３和＞３阳性淋巴结分组比较适宜。

The stastistical analysis of the stage of positive lymph node w as made in 159 patients who underwent curative resection of rectal cancer.Subdivision according to the number of positive nodes demonstrated the local recurrence to be 22 percent and the five-year survival rate 60 percent in patients with one to three nodes whereas the local recurrence and five-year survival rate in those with four or more were 43 percent and 35 percent respectively(a remarkable difference).But no significant difference was revealed in subdivision of one fo four and five or more,Classification according to our criterion for the site of nodes division didn't reveal any sharp difference in both local recurrence and postoperative survival rate.The authors conclude that the number of nodal metastases has a high impact on prognosis of rectal cancer patients and that the subdivision of patients for predicting outcome into 1～3and>3 positive lymph node groups is feasible.
