ABSTRACT

Objective To investigate the clinical characterisitics of chronic panereatitis(CP) with mass.Methods The clinical features,radiologieal and pathologic records of 39 cases of chronic pancreatitis with mass confirmed pathologically between January 2005 to December 2007 were retrospectively reviewed,and compared with 17 surgical pathologically confirmed patients with pancreatic cancer.Results The jaundice was found in 14 of 39 patients with pancreatits and 1 of 17 patients with pancreatic cancer,with significant difference between two groups(χ2=0.111,P=0.045).Elevated serum CEA and CA19-9 were found in 0 and 12 patients with pancreatitis.respectively,and 3 and 11 patients with pancreatic cancer,respectively(P=0.025 and=0.018,respectively).CT examination showed that the atrophy pancreas and the infiltration of surrounding and blood vessels were found in 0 and 5 patients with pancreatitis or 3 and 8 patients with pancreatic cancer,respectively(all P values＜0.05).The magnetic resonance cholangiopanereatography (MRCP) examination revealed that dilation of bile and pancreatic ducts,and calculus in pancreas duct were found in 14,2 and 15 patients with pancreatitis,or 11,6 and 2 patients with pancreatic cancer,respectively(all P values ＜0.05).Pancreatic cancer was confiremed by endoscopic ultrasonography guided fine needle aspiration(EUS-FNA)in 10 of 14 patients with pancreatic cancer,but none in 18 patients with pancreatitis.Conclusions It is difficult to diagnose CP with mass,but it will helpful ifassists diagnosis with clinical features,tumor markers and image examinations,especially with biopsyexamination.
