Abstract
Purpose: The significance of serum levels of CEA and CA19-9 in forming a prognosis for colorectal cancer patients remains as subject for debating. The aim of this study is to assess their correlations with tumor pathology and their prognostic values.
Methods: We analysed the data on 274 patients with colorectal cancer who had been treated by resection from Jan. 1997 to Aug. 2005. Correlation of the preoperative serum values of CEA and CA19-9 with clinocopathologic features, including prognosis, of the patients was investigated.
Results: The positivity rates of the two tumor markes were significantly correlated with tumor size, differentiation, TNM staging, venous invasion, and neural invasion. In addition, the positivity rate of CEA was related to lymphatic invasion and that of CA19-9 to gender. In the univariate analysis, CEA (P＜0.001), CA19-9 (P＜0.001), tumor size (P=0.011), TNM staging (P＜0.001), lymphatic invasion (P=0.003), venous invasion (P＜0.001), neural invasion (P＜0.001), and differentiation (P=0.023) correlated with survival of the patients. In the stepwise multivariate analysis, an advanced TNM stage (P＜0.001), positive venous invasion (P=0.011), and positive neural invasion (P=0.013) were independent prognostic factors for poor survival.
Conclusions: Our results demonstrated that high serum levels of tumor markers were associated with more aggressive cancers, but in the multivariate analysis, CEA and CA19-9 were found not to be independent prognostic factors.
