Outline of Final Research Achievements |
DNA was extracted from 38 pancreatic tumors and CTNNB1 gene mutation was analyzed by next generation sequencer. Seven out of 7 solid-pseudopapillary neoplasm showed a single base pair missence mutations in exon 3 of CTNNB1 with variant frequency of 5.4 to 48.8%. DNA was extracted from cyst fluid or pancreatic juice in 5 patients with intraductal papillary mucinous neoplasms. We analyzed 36 cancer related gene mutations by next generation sequencer. Four GNAS and 2 KRAS mutations were detected with variant frequency of 2-29.8 and 6-21% respectively.
