Targeted Therapies for Pancreatic Cancer: Overview of Current Treatments and New Opportunities for Personalized Oncology

Simple Summary The lack of early diagnosis and the absence of suitable biomarkers coupled with resistance to available therapeutic options render pancreatic cancer one of the deadliest cancer types. Therefore, new therapeutic approaches are needed to be developed, taking into account the genetic and molecular profile of pancreatic tumors. Here, we critically review past and current efforts that have resulted in the development of potent and specific antitumor compounds that, if employed in the appropriate combination therapy, may change this recalcitrant cancer type into a manageable one. Cytotoxic chemotherapy remains the only treatment option for most pancreatic ductal adenocarcinoma patients. Currently, the median overall survival of patients with advanced disease rarely exceeds 1 year. The complex network of pancreatic cancer composed of immune cells, endothelial cells, and cancer-associated fibroblasts confers intratumoral and intertumoral heterogeneity with distinct proliferative and metastatic propensity. This heterogeneity can explain why tumors do not behave uniformly and are able to escape therapy. The advance in technology of whole-genome sequencing has now provided the possibility of identifying every somatic mutation, copy-number change, and structural variant in a given cancer, giving rise to personalized targeted therapies. In this review, we provide an overview of the current and emerging treatment strategies in pancreatic cancer. By highlighting new paradigms in pancreatic ductal adenocarcinoma treatment, we hope to stimulate new thoughts for clinical trials aimed at improving patient outcomes.
