Resumen
Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive and deadliest cancers worldwide, with an overall survival rate of <10% at 5 years. For most patients with unresectable or recurrent PDAC, few therapeutic options are available, with limited efficacy. Furthermore, there is an almost complete absence of validated predictive factors. At present, microRNAs represent a promising diagnostic, prognostic, and predictive method for the clinical management of patients, avoiding inappropriate treatments.
