[Predictive value of lymph node ratio for postoperative distant metastasis of stage III colorectal cancer].

Objective: To investigate the predictive value of metastatic lymph node ratio for postoperative distant metastasis in patients with colorectal cancer.

Methods: The clinicopathological data were collected from 180 patients with colorectal cancer who underwent surgical resection in General Hospital of PLA between from January, 2007 to January, 2012. The patients were divided into 2 groups according to the presence of distant organ metastasis and the clinicopathological factors were analyzed with Chi-square test and logistic regression.
