Current controversies in the stage-specific multidisciplinary management of pancreatic cancer.

Encouraging therapeutic approaches and treatment regimens for patients with both localized and metastatic pancreatic cancer have emerged over the last 5 years. However, these new strategies have brought important challenges and controversy. Clinical staging criteria are constantly evolving. No system has been uniformly adopted, limiting our understanding of the role of both pancreatectomy and neoadjuvant therapies for localized disease. The role of radiation therapy for the treatment of both resectable and unresectable pancreatic cancer remains unclear despite multiple prospective studies. Although two new systemic chemotherapy regimens have essentially transformed the care of many patients with metastatic cancer, criteria to guide their use in the general population have yet to be clearly established. Herein we provide an overview of these important controversies in the context of a broad update on the stage-specific management of patients with newly diagnosed pancreatic cancer.
