Fig. 2From: Blood serum proteins as biomarkers for prediction of survival, locoregional control and distant metastasis rate in radiotherapy and radio-chemotherapy for non-small cell lung cancerInfluence of tumor pathology (a), EPO concentration (b) and VEGF concentration (c) on overall survival in a group of 148 patients with non-small cell lung cancer treated with curative radio-chemotherapy or radiotherapy. The differences in overall survival are highly significant (p = 0.005; p = 0.008; p = 0.006 in groups a, b, c respectively). Median EPO and VEGF concentration was selected as a cut-offBack to article page
