Abstract:

Objective

To explore the predictive value of preoperative tumor markers CEA and CA19-9 in predicting distant metastasis of colorectal cancer.

Methods

The clinical data of 2 758 patients with colorectal cancer who underwent radical resection of R0 were analyzed retrospectively, including age, sex, degree of tumor differentiation, tumor diameter, tumor site, CEA, CA19-9, tumor histological type and distant metastasis. The factors that may reflect distant metastasis in patients with colorectal cancer were analyzed by univariate and multivariate analysis, and then appropriate variables were selected to construct the Nomogram. The recognition of the Nomogram is verified by the calibration curve. Subject operating characteristic analysis (ROC) was used to compare the ability of the Nomogram to predict distant metastasis in patients with colorectal cancer.

Results

Univariate and multivariate results showed that preoperative CEA, CA19-9, tumor site and tumor differentiation were important factors reflecting distant metastasis in patients with colorectal cancer(P<0.05). The above variables are used to construct the Nomogram, and the ROC value of the prediction model is 0.771 (95% confidence interval: 0.730~0.813).

Conclusion

The predictive model constructed by preoperative CEA and CA19-9 combined with basic pathological information is an effective method for non-invasive prediction of distant metastasis in patients with colorectal cancer.
