Formalin-fixed paraffin-embedded tumor specimens were used for DNA extraction. Quantitative polymerase chain reaction (qPCR) for MET CNG and sequencing for HGF DATE truncation (&lt; 25 deoxyadenosines instead of 30) were used. Results were analyzed for association with disease-free survival (DFS) and overall survival (OS). To assess the reliability of the qPCR measurement, a random sample of cases was reanalyzed using an alternative assay (fluorescent in situ hybridization [FISH]) with calculation of the intracorrelation coefficient (ICC). <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> In 216 assessable patients, MET CNG five or more copies and homozygous HGF-truncated DATE occurred in 21 patients (10%) and 30 patients (13%), respectively. Patients with MET CNG five or more copies (MET-positive) showed significantly worse prognosis with multivariate hazard ratio (HR) of 3.02 (95% CI, 1.71 to 5.33; P &lt; .001) for DFS and multivariate HR of 2.91 (95% CI, 1.65 to 5.11; P &lt; .001) for OS. The agreement between qPCR and FISH was high, with ICC = 0.9% (95% CI, 0.81% to 0.95%; the closer the ICC is to 1, the greater is the agreement). HGF-truncated DATE did not show relevant prognostic effect. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p> In this study, qPCR revealed approximately 10% of white patients with gastric cancer harboring MET CNG of five or more copies. This marker was significantly associated with unfavorable prognosis. This information is relevant to the current clinical development of anti-MET compounds. <\/jats:p><\/jats:sec>","DOI":"10.1200\/jco.2011.36.7706","type":"journal-article","created":{"date-parts":[[2011,11,1]],"date-time":"2011-11-01T04:30:35Z","timestamp":1320121835000},"page":"4789-4795","source":"Crossref","is-referenced-by-count":143,"title":["Genetic Activation of the <i>MET<\/i> Pathway and Prognosis of Patients With High-Risk, Radically Resected Gastric Cancer"],"prefix":"10.1200","volume":"29","author":[{"given":"Francesco","family":"Graziano","sequence":"first","affiliation":[{"name":"Francesco Graziano, Paola Lorenzini, Silvia D'Emidio, Vincenzo Catalano, Valerio Sisti, Giammaria Fiorentini, Costantino Zingaretti, and Michele De Nictolis, Azienda Ospedaliera \u201cOspedali Riuniti Marche Nord,\u201d Pesaro;
