Core Tip

Core tip: We provide for the first time a blood-based assay for transcript quantification of the metastasis inducer Metastasis Associated in Colon Cancer 1 (MACC1) in a prospective study of gastric cancer patients. MACC1 is a strong prognostic biomarker for tumor progression and metastasis in a variety of solid cancers. We discriminated tumor-free volunteers and gastric cancer patients (all P < 0.001, sensitivity 0.68 (95%CI: 0.45-0.85), specificity 0.89 (95%CI: 0.77-0.95) of each disease stage (P < 0.05 for each). Shorter survival correlated with high circulating MACC1 transcript levels (P = 0.0015). Thus, circulating MACC1 transcript levels in plasma of gastric cancer patients are of diagnostic value and are prognostic for patient survival.
