To evaluate its diagnostic efficacy, we performed BCL10 immunohistochemistry and evaluated molecular markers correlated to pancreatic tumor lineages (neuroendocrine markers and a mutation analysis of KRAS and GNAS) using samples from 126 pancreatic tumors (17 ACCs, 24 pancreatic ductal adenocarcinomas, 4 adenosquamous carcinomas, 9 intraductal papillary mucinous neoplasms, 10 mucinous cystic neoplasms, 44 neuroendocrine tumors, 9 serous cystic tumors and 10 solid-pseudopapillary neoplasms).

K-ras gene mutation in patients with chronic pencreatitis did not seem to be related to the development of pancreatic neoplasm during the follow-up period, and analysis of K-ras gene mutation seems of little use for diagnosing pancreatic neoplasm in patients with chronic pancreatitis.
