PG - 123 LID - 10.1186/1471-2407-8-123 [doi] AB - BACKGROUND: Hypoxia influences tumor growth by inducing angiogenesis and genetic alterations. Hypoxia-inducible factor 1alpha (HIF-1alpha), p53, and vascular endothelial growth factor (VEGF) are all important factors in the mechanisms inherent to tumor progression. In this work, we have investigated the clinicopathologic significance of HIF-1alpha, p53, and VEGF expression and preoperative serum VEGF (sVEGF) level in gastric cancer.We immunohistochemically assessed the HIF-1alpha, p53, and VEGF expression patterns in 114 specimens of gastric cancer. Additionally, we determined the levels of preoperative serum VEGF (sVEGF). RESULTS: The positive rates of p53 and HIF-1alpha (diffuse, deep, intravascular pattern) were 38.6% and 15.8%, respectively. The VEGF overexpression rate was 57.9%. p53 and HIF-1alpha were correlated positively with the depth of invasion (P = 0.015, P = 0.001, respectively). Preoperative sVEGF and p53 levels were correlated significantly with lymph node involvement (P = 0.010, P = 0.040, respectively). VEGF overexpression was more frequently observed in the old age group (> or = 60 years old) and the intestinal type (P = 0.013, P = 0.014, respectively). However, correlations between preoperative sVEGF level and tissue HIF-1alpha, VEGF, and p53 were not observed. The median follow-up duration after operation was 24.5 months. HIF-1alpha was observed to be a poor prognostic factor of disease recurrence or progression (P = 0.002). CONCLUSION: p53, HIF-1alpha and preoperative sVEGF might be markers of depth of invasion or lymph node involvement. HIF-1alpha expression was a poor prognostic factor of disease recurrence or progression in patients with gastric cancers.
