Abstract:
Objective To explore the relationship between D-dimer and carcinoembryonic antigen (CEA) levels before treatment and clinicopathologic features of colorectal cancer and the value of prognosis. Methods A total of 209 patients who underwent radical colorectal cancer surgery in Wujin Hospital Affiliated of Jiangsu University from January 2017 to December 2018 were selected as the study objects. D-dimer and CEA levels were detected before treatment,and their relationship with clinicopathologic features and prognosis were analyzed. Results Before treatment,D-dimer was correlated with tumor site (P<0.001),pathological type (P=0.007),depth of invasion (P<0.001),lymph node metastasis (P=0.007) and tumor stage (P<0.001). CEA was associated with pathological type (P<0.001) and tumor stage (P=0.035). The postoperative tumor-free survival rate (x2=21.659,P<0.001) and overall survival rate (x2=22.887,P<0.001) in patients with both D-dimer and CEA positive expression before treatment were significantly lower than those in patients without both positive expression. The area under the curve for predicting overall survival of colorectal cancer patients with both D-dimer and CEA positive before treatment was 0.723. Pearson correlation analysis showed a positive correlation between D-dimer and CEA in colorectal cancer patients before treatment (r=0.144,P=0.037). Cox proportional risk regression analysis showed that simultaneous positive D-dimer and CEA,lymph node metastasis and distant metastasis were independent risk factors affecting postoperative tumor-free survival and overall survival of colorectal cancer patients (P<0.05). Conclusion D-dimer and CEA before treatment are of great value in the diagnosis and prognosis of colorectal cancer,and the combination of D-dimer and CEA has a definite effect on the accuracy of postoperative survival assessment of colorectal cancer.
