Despite improvements in surgical management, only a minority of patients en
joy long-term survival following pancreaticoduodenectomy for adenocarcinoma
of the pancreas. Adjuvant therapy consisting of 5-fluorouracil and irradia
tion has improved median and 5-year survival rates; however, at least one t
hird of eligible patients do not receive postoperative adjuvant therapy bec
ause of delayed recovery following pancreaticoduodenectomy. This has led to
the development of treatment schedules incorporating the delivery of syste
mic therapy and/or chemoradiation prior to surgery. This article briefly ou
tlines the history of adjuvant therapy for adenocarcinoma of the pancreas a
nd reviews the available literature on neoadjuvant therapy for localized pa
ncreatic cancer including investigational therapies under clinical trial ev
aluation.
