Abstract
BACKGROUND: The current study aims to investigate the expression of circRNA has_circ_0141633 in the tissues and serum of patients with gastric cancer (GC).
METHODS: RT-qPCR was used to detect the expression of has_circ_0141633 in the tissues and serum of patients with GC. Pearson's correlation was used to analyze the relationship between the level of serum and tissue has_circ_0141633 in GC patients. Receiver characteristic curve (ROC) was used to evaluate the diagnostic value of the expression of serum has_circ_0141633 in GC patients. The relationship between serum has_circ_0141633 and the clinicopathological characteristic was analyzed in GC patients. Kaplan-Meier method was used to analyze the survival rate.
RESULTS: The level of serum and tissue has_circ_0141633 in GC patients was significantly higher than that in controls. Pearson's correlation analysis showed a positive correlation between serum and tissue has_circ_0141633 levels (r = 0.846, p < 0.05). ROC curve analysis showed that the AUC of serum has_circ_0141633 was 0.835 (95% CI: 0.753 - 0.916), with the sensitivity and specificity of 84.5% and 93.6%. The level of serum has_circ_0141633 was significantly increased according to the malignant characteristics of tumor diameter, differentiation, lymph node metastasis, and TNM stage. The median survival time of GC patients with low expression of has_circ_0141633 was longer than that of GC patients with high expression of has_circ_0141633.
CONCLUSIONS: In summary, upregulation of serum has_circ_0141633 may be expected to be a specific molecular marker for the diagnosis and evaluation of malignant GC.
