5 Pancreatic Adenocarcinoma Pancreatic ductal adenocarcinoma (PDAC) is now the third leading case of cancer deaths in the USA Although there have been recent advancements in systemic therapy for metastatic disease with the FOLFIRINOX and gemcitabine/nabpaclitaxel regimens, the survival rates for PDAC remain poor The most established risk factor pancreas cancer is cigarette smoking and is associated with about 25% of the cases. A minority of PDAC patients (less than 20%) are diagnosed at an early stage where surgery may be beneficial Ø In these patients, accurate staging is required to define potential resectability In patients with resectable PDAC, the current standard of care is upfront surgery followed by adjuvant therapy 1.

40 Conclusions 1 FOLFIRINOX is an adjuvant standard in pancreas cancer. PS, organ function, recovery from surgery Perioperative chemotherapy and preoperative hypofractionated radiotherapy is an emerging option for resectable and borderline resectable pancreas cancer Should we incorporate hypofractionated XRT to FOLFIRINOX? Alliance Trial Wake Forest Baptist Medical Center 41

41 Conclusions 2 Participation in clinical trials is paramount and should be the first line of choice. Folfirinox is an option in good organ function and PS 0-1. Gem/Nab is an option for patients with PS 0-2. Liposomal Irinotecan + 5- FU is the second-line option based on phase III data. Level 1 by NCCN guidelines. The sequence of treatment is dictated by patient characteristics and physician choice rather than efficacy.

42 Conclusions 3 In metastatic pancreas cancer FOLFIRINOX followed by maintenance 5FU is an option. Activity in MSI-High tumors is stablished Targeted Therapy and immunotherapy combo are emerging. Biomarkers to predict benefit from therapy are desperately needed. Wake Forest Baptist Medical Center
