Abstract: BACKGROUND:Plasma carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), and cancer antigen 72-4 (CA72-4) are common markers which are useful in the diagnosis and prognosis of GC. However, their sensitivity and specificity in GC remain unsatisfactory. Identification of cancer diagnosed-biomarkers would be of great value. OBJECTIVE: Evaluate the diagnostic and prognostic value of LINC00086 and miR-214 in GC. METHODS:In this study, we determined the expression of LINC00086 and miR-214 in GC by qRT-PCR. Additionally, we investigated the relationship between various clinicopathological features of GC patients and LINC00086 or miR-214 expression, and evaluated the diagnostic and prognostic value of LINC00086 and miR-214 in GC. RESULTS: In this study, we found that plasma LINC00086 expression was significantly lower, whereas plasma miR-214 expression was significantly higher in GC patients than in normal individuals. LINC00086 and miR-214 exhibited high sensitivity and specificity in diagnosing GC. Additionally, GC patients with low LINC00086 or high miR-214 expression were likely to have larger tumors, lymphatic metastasis, larger TNM stage, and higher CEA and CA19-9 levels. Moreover, GC patients with low LINC00086 or high miR-214 expression showed lower survival rates. Lymphatic metastasis, LINC00086, and miR-214 are independent factors affecting patient diagnosis. CONCLUSIONS: LINC00086 and miR-214 are potentially diagnostic and prognostic markers for GC.
