Therapeutic Approach to Cystic Neoplasms of the Pancreas.

Management of cystic neoplasms of the pancreas is challenging as it relies on radiologic and cyst fluid markers to discriminate between benign and pre-cancerous lesions, however their ability to predict malignancy is limited. While asymptomatic serous cystadenomas can be managed conservatively, mucinous cystic neoplasms and intraductal papillary mucinous neoplasms are more difficult to manage. A selective approach, based on the preoperative likelihood of high-grade dysplasia or invasive disease, is the standard of care. Research is focusing on the development of pre-operative markers for identifying high risk lesions, which will spare patients with low-risk or benign lesions the risks of pancreatectomy.
