Serum hsa_circ_0007534 as a diagnostic biomarker for ovarian cancer.

ObjectiveTo investigate the implications of serum hsa_circ_0007534 levels in ovarian cancer (OC) patients.MethodsA retrospective analysis was conducted on the clinical data of 102 OC patients, and 102 healthy controls (HCs) were included in this study. Serum levels of hsa_circ_0007534 were measured using qPCR. The relationship between circRNA levels and clinicopathologic characteristics was analyzed. Additionally, the diagnostic performances of serum hsa_circ_0007534 and CA-125 levels in OC patients were evaluated using Receiver Operating Characteristic (ROC) curve analyses.ResultsOC patients had significantly elevated serum hsa_circ_0007534 levels compared to HCs, allowing a differentiation between OC patients and HCs. Higher serum hsa_circ_0007534 levels were associated with more aggressive disease features and poorer overall survival. Patients with elevated hsa_circ_0007534 levels tended to have worse clinical outcome compared to those with lower levels. Multivariate analyses indicated that high hsa_circ_0007534 levels were independently associated with poorer outcome. Furthermore, serum hsa_circ_0007534 levels effectively distinguished between chemoresistant and chemosensitive patient groups.ConclusionsSerum hsa_circ_0007534 levels may serve as valuable predictors of prognosis in OC patients.
