Pancreatic adenocarcinoma (PDAC) remains a highly fatal disease that is increasing in incidence. PDAC can be classified according to resectability status with 3 nonmetastatic groups defined: resectable, borderline resectable, and locally advanced PDAC (LAPC). Delineating these subtypes is important with the optimal treatment approach dictated by high-quality CT imaging and multidisciplinary team discussion. Patients with LAPC are thought unresectable and are therefore rarely cured. In these patients, chemotherapy remains the mainstay of treatment. Aggressive approaches in this cohort are increasingly employed. Local therapies after induction chemotherapy including standard fractionation radiation, stereotactic body radiotherapy (SBRT), and irreversible electroporation (IRE) are being investigated in an attempt to improve long-term control. In some cases, responses to neoadjuvant therapy may facilitate surgical resection. Biomarkers that can select patients most likely to benefit from these options are urgently needed. This review aims to highlight the emerging treatment of patients with LAPC and to discuss current trials.
