Pancreatic neuroendocrine tumors ( PNETs) are a class of tumors that derived from the pluripotent neural stem cells of pancreas.In recent years, some data shows a yearly increasing trend of the incidence of PNET. However, the overall incidence of PNETs is low.Generally, the tumor volume is small（<1cm）and the growth rate is slow (several months or several years).But,its symptoms can be periodical expression or no symptoms for years.Furthermore,before the onset of symptoms,the tumors have transfered to liver and bones and other parts of the body.At this point, the tumor volume usually exceeds 2cm, which is easily confused with endocrine primary disease, resulting in misdiagnosis and missed diagnosis. However, some pancreatic neuroendocrine tumors, malignant level is lower.If it can get a early diagnosis and timely treatment in the clinical,it will get a better prognosis. And in recent years, with the change of the academic understanding of pancreatic neuroendocrine tumors,its diagnosis and treatment patterns also change accordingly,it has become a research hot spot. In view of the situation,in this article ,we will write a review of PNETs mainly from its diagnosis,treatment and prognosis.
