Abstract
OBJECTIVE
To explore the relationship between serum circular RNA ERBB2 (CircERBB2) levels and clinicopathological features and prognosis of patients with non-small cell lung cancer (NSCLC).
METHODS
In this retrospective study, 87 patients with NSCLC (NSCLC group) and 85 patients with benign lung disease (benign lung disease group) in the First Affiliated Hospital of Yangtze University from March 2016 to February 2019 were enrolled; in addition, another 87 healthy subjects were selected as the control group. Serum levels of CircERBB2, cytokeratin 19 fragment (CYFRA21-1) and carcinoembryonic antigen (CEA) in each group were detected, and their relationship with the prognosis of NSCLC patients as well as their diagnostic value was analyzed. The serum CircERBB2 levels in NSCLC patients with different clinicopathological characteristics were compared, and the correlation of serum level of CircERBB2 with CircERBB2 as well as CYFRA21-1 was analyzed.
RESULTS
The serum CircERBB2, CYFRA21-1 and CEA levels in the control group, benign lung disease group and NSCLC group were gradually increased (P<0.05). In the NSCLC group, serum CircERBB2 level was correlated with lymph node metastasis, tumor diameter and TNM stage (P<0.05). The areas under the curve (AUCs) of serum CircERBB2, CYFRA21-1, and CEA in diagnosing NSCLC were 0.871, 0.693, and 0.861, with cut-off values of 2.27, 4.45 ng/mL, and 18.49 ng/mL, respectively. The sensitivity was 80.5%, 65.5%, 78.2%, the specificity was 87.1%, 74.1%, 88.2%, respectively. The AUC and sensitivity of CircERBB2 combined with CEA in diagnosing NSCLC was 0.938 and 94.3%, respectively. The serum CircERBB2 level was positively correlated with CYFRA21-1 and CEA in the NSCLC group (P<0.05); and the levels of the above three serum indexes were significantly higher in the death group than those in the survival group (all P<0.05). The 36-month cumulative survival rate of patients in the CircERBB2 low expression group was longer than that in the CircERBB2 high expression group (P<0.05).
CONCLUSION
Serum CircERBB2 is highly expressed in NSCLC patients, and closely related to disease progression, so it has good prognostic value.
