Abstract:
Objective To explore the expression and significance of serum DKK1 in patients with gastric cancer. Methods We selected 170 gastric cancer patients (gastric cancer group) and 170 subjects with non-gastric cancer during the same period (control group). ELISA was used to detect the DKK1 level. The ROC curve was used to evaluate the diagnostic performance, and we analyzed the relation between DKK1 level and age, gender, family history of gastric cancer, cigarette smoking, alcohol consumption, tumor size, TNM stage, infiltration depth, lymph node metastasis, liver metastasis, vascular invasion, perineural invasion. Results The serum DDK1 level in GC patients was higher than that in control group (P < 0.0001). ROC curve showed that the possible optimal cut-off value of DKK1 for gastric cancer patients was 167.8 pg/ml, AUC was 0.908, sensitivity was 80.59%, and specificity was 84.71%. There was no significant relation between the serum DKK1 level and age, gender, family history of gastric cancer, cigarette smoking, alcohol consumption, tumor size, liver metastasis, vascular invasion or distant metastasis (all P > 0.05). However, DKK1 level was significantly related with TNM stage, infiltration depth, lymph node metastasis and perineural invasion (all P < 0.05). Conclusion Serum DKK1 level is higher in gastric cancer patients than that of control group and related with the severity of lesions, which indicates that serum DKK1 may be a potential biomarker for gastric cancer screening.
