PURPOSES: This study was intended to determine the diagnostic significance of signal peptide-CUB-EGF domain-containing protein 1 (SCUBE 1) levels in gastric cancer. METHODS: This retrospective study was conducted with patients with gastric cancer. SCUBE 1 titers of plasma in patients with gastric cancer were determined using an enzyme-linked immunosorbent assay (ELISA). RESULTS: SCUBE 1 titers of gastric cancer patients were significantly higher compared with the control group (P=0.0001). At a SCUBE 1 cut-off point of 43 ng/mL, sensitivity was 67%, specificity 91%, positive predictive values (PPV) 92% and negative predictive values(NPV) 63%. SCUBE 1 levels of patients with methastase were not different from patients without methastase (P> 0.05). DICUSSIONS: SCUBE 1 levels in patients with gastric cancer were found higher compared to healthy subjects.
