| Outline of Final Research Achievements |
Whole exon sequencing (WES, Life Technologies) and gene expression profiling (GEP, Agilent Technologies) were performed for 22 patients who underwent pancreatectomy for pancreatic cancer. The impaired expression of KRAS, TP53 and p16 genes of 4 mafor genes which were frequently mutated in pancreatic cancer was detected in fifteen, twelve and four cases, respectively. In the tumor tissue, many cases increased expression of tyrosine kinase receptors. The hyper-expression of FGFR3 and ERBB3 was identified in six cases each. Moreover, JAK3 and CSFIR were identified in two cases each. The recurrence-free and overall survival rate among the patients with the increased expression of FGFR3 were significantly poorer than those without the increased expression of FGFR3 (P=0.047 and P=0.048, respectively).
