摘要:: The aim of this study was to evaluate the mRNA expression pattern of growth- and survival-related genes and assess their prognostic significance in patients with advanced pancreatic cancer.,In total, 98 patients were included in this retrospective translational research study and were evaluated for Kirsten rat sarcoma viral oncogene homolog (KRAS) mutational status, and v-akt murine thymoma viral oncogene homolog 1 (AKT1), AKT serine/threonine kinase 2 (AKT2), AKT serine/threonine kinase 3 (AKT3), cyclin D1 (CCND1), epidermal growth factor receptor (EGFR), mitogen-activated protein kinase 1 (MAPK1), hepatocellular growth factor receptor (MET), avian myelomatosis viral oncogene homolog (MYC), nuclear factor kappa B subunit 1 (NFKb1), phosphatase and tensin homolog (PTEN) and mechanistic target of rapamycin (FRAP1) genes mRNA expression. Among these patients, 73 received first-line gemcitabine combined with erlotinib (N=57) or gefitinib (N=16).,KRAS mutation did not correlate with mRNA gene expression. Unsupervised hierarchical clustering according to mRNA gene expression successfully distinguished four prognostically distinct groups of tumors. Overexpression of all genes was associated with best prognosis, while suppression or heterogeneous expression patterns of the examined genes were associated with expression patterns of growth- and survival-related genes, classifying pancreatic tumors into distinct groups with possibly different outcomes.
