Study on risk factors for liver metastasis after radical resection of colon cancer

Objective To explore the risk factors for liver metastasis after radical resection of colon cancer. Methods The clinical pathological data and situation of postoperative follow-up of 306 patients with colon cancer were retrospectively analyzed. Results The incidence of liver metastasis from colon cancer was 23. 5%( 72 /306). Univariate analysis showed that age,histological differentiation,gross type,vascular invasion,lymph node metastasis,number of lymph nodes dissected,preoperative serum level of CEA and operating time were relevant to liver metastasis( P 0. 05). Logistic regression analysis showed that histological differentiation,vascular invasion and lymph node metastasis were correlated with liver metastasis( P 0. 05). Conclusion Patients with poorly differentiated colon canceer,vascular invasion or lymph node metastasis have higher chance of liver metastasis after radical resection of colon cancer.
