Fig. 3From: 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 OPN concentration on overall survival in a group of 171 patients with squamous-cell cancer (a) and 44 patients with adenocarcinoma (b). The difference in overall survival according to biomarker concentration is highly significant among the patients with squamous cell cancer (p < 0.0001), but not among the patients with adenocarcinoma. 0.18Back to article page
