Indications for Radiation in Pancreatic Adenocarcinoma: A Review.

Pancreatic adenocarcinoma remains a deadly disease with 5 year overall survival of 10% among all stages. Standard of care for resectable disease remains surgical resection and adjuvant systemic therapy, but paradigms for borderline resectable and unresectable cases remain more nuanced. Radiation has been explored in the neoadjuvant, adjuvant, and definitive settings in a variety of randomized and non-randomized trials with mixed results. There is strong evidence to support the use of neoadjuvant radiation for borderline resectable pancreatic cancer. Utilization of radiation in the adjuvant setting remains unclear while the results of radiation therapy oncology group (RTOG) 0848 are pending.
