Gastric Cancer: Overexpression of Hypoxia-Inducible Factor 1 as a Prognostic Factor
Despite a worldwide decline in incidence, gastric cancer remains the fourth most common cancer and the second most frequent cause of death from cancer, accounting for 10.4% of cancer deaths worldwide (Parkin, 2004). Though the prognosis of resectable gastric cancer remains fair, the treatment of advanced or recurrent gastric cancer is still far from satisfactory. Currently, the only curative treatment for gastric cancer is a surgical resection of the primary tumor with an appropriate lymphadenectomy because the disease is considered to be resistant to chemotherapy and radiotherapy (Griffiths et al., 2005). Patients with early gastric cancer are in the minority and the disease typically presents at an advanced stage, which often precludes a curative surgical resection. Even in patients who have an apparently curative resection, approximately, a quarter of all individuals tend to progress and develop either recurrent or metastatic disease.
