Interdisciplinary management of an intraductal papillary mucinous neoplasm of the pancreas.
BACKGROUND
Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is less common than classic invasive ductal adenocarcinoma of the pancreas but is being diagnosed with greater frequency since its clinicopathologic features are now clearly defined. Often multifocal in its existence along the pancreatic duct, IPMN is associated with a significant risk for recurrence and warrants vigilant surveillance, even after a margin-negative resection.


METHODS
The authors present a case highlighting important features in the diagnosis, workup, and management of IPMN. They also review existing literature highlighting epidemiology, findings of molecular studies, and current treatment recommendations.


RESULTS
Physicians and patients must carefully weigh the risks and benefits associated with treatment options. Limited resection in a patient with a high likelihood of multifocal disease preserves pancreatic parenchyma and reduces the risk of developing pancreatic endocrine and exocrine insufficiency. Though the risk of developing invasive cancer in the remnant is small, the prognosis is worse if it does develop. Conversely, total pancreatectomy eliminates the risk of future malignancy but involves life-long insulin and exogenous pancreatic enzyme dependence and significant associated morbidity.


CONCLUSIONS
Decision making for effective treatment of IPMN is complex and requires attention to detail by an interdisciplinary team with experience in the diagnosis and management of these tumors. Treatment must be individualized based on patient life expectancy in terms of remaining years and overall quality. Molecular profiling of these lesions may allow for more precise tailoring of treatment in the future.
