Abstract:
〈 b 〉 〈 i 〉 Background: 〈 /i 〉 〈 /b 〉 Vascular adhesion protein-1 (VAP-1) is a glycoprotein that mediates tissue-selective lymphocyte adhesion in a sialic acid-dependent manner. The prognostic importance of VAP-1 was determined in various human cancers. The aim of this study was to determine the relationship between VAP-1 and prognosis of gastric cancer. 〈 b 〉 〈 i 〉 Materials and Methods: 〈 /i 〉 〈 /b 〉 Serum of operable and metastatic gastric cancer patients was collected before treatment (surgery, radiotherapy, and/or chemotherapy). VAP-1 levels were measured by enzyme-linked immunosorbent assay. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 A total of 86 gastric cancer patients (32 female, 54 male) were included in the study. Curative surgical treatment was performed in 54 (62.8%) patients. The mean serum VAP-1 level was 324.4 pg/ml and significantly higher in operable gastric cancer patients compared to metastatic gastric cancer patients (383.1 ± 173.5 vs. 225.2 ± 113.9 pg/ml; p 〈 0.001). When a cut-off value for VAP-1 of 218.8 pg/ml was determined by receiver operating characteristic (ROC) curves for presence of metastasis, sensitivity and specificity were 81.5 and 65.6%, respectively. Patients with decreased VAP-1 levels had a significantly poorer prognosis compared to patients with increased serum VAP-1 levels (median survival 8.2 vs. 23.5 months; p 〈 0.001). Multivariate analysis showed that VAP-1 is an independent prognostic factor of gastric cancer (odds ratio 2.3, 95% confidence interval 1.1-4.9; p = 0.032). 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 A low serum VAP-1 level may be an indicator of poor prognosis in gastric cancer. This study demonstrated that low serum VAP-1 levels are associated with poor prognosis in gastric cancer patients.
