Abstract    Chronic pancreatitis is closely related to pancreatic cancer. Patients with chronic pancreatitis have a markedly increased risk of pancreatic cancer compared with the general population. The nature of the transition between chronic inflammation and cancer is still a subject of debate. In the setting of CP, inflammatory cells, cytokines, chemokines, and activated signaling pathways play a role in the transformation of normal ductal epithelium to metaplastic metaplasia and early neoplastic lesions (pancreatic intraepithelial neoplasia (PanIN)), which eventually give rise to pancreatic cancer.Mass-forming chronic pancreatitis is similar with pancreatic cancer in clinical manifestation and imaging characteristic.It is difficult to differentiate mass of the head of pancreas. EUS-FNA and PET/CT is useful to differential diagnosis.

Key words: chronic pancreatitis, pancreatic cancer, pathogenesis , diagnosis
