Objective To investigate the diagnostic value of Bcl-2, miR-451 and Th17 cells in esophageal cancer and their relation with recurrence.
Methods We selected 101 patients with esophageal cancer as the experimental group and 95 healthy patients as the control group. The correlation between the clinicopathological characteristics and the level of each peripheral blood index was analyzed. The ROC curve was used to analyze the diagnostic value of each peripheral blood index. Multiple linear regression analysis was used to analyze the relation between each index and tumor recurrence.
Results Peripheral blood Bcl-2, miR-451 and Th17 cells in the experimental group were higher than those in the control group (all P < 0.05); differentiation degree, clinical stage, tumor diameter and lymph node metastasis were positively correlated with the levels of Bcl-2, miR-451, and Th17 cells (all P < 0.05). Bcl-2, miR-451 and Th17 cells in relapsed patients were higher than those in non-relapsed patients (all P < 0.05); after controlling other factors such as differentiation degree, clinical stage, tumor size and lymph node metastasis, the levels of Bcl-2, miR-451 and Th17 cells were significantly correlated with recurrence (all P < 0.05).
Conclusion Bcl-2, miR-451 and Th17 cells in peripheral blood of esophageal cancer patients are abnormally expressed and their expression are closely related to differentiation degree, clinical stage and recurrence. The combined detection could provide an objective basis for clinical diagnosis and prognosis assessment.
