HPB. Triple approach strategy for patients with locally advanced pancreatic carcinoma

Alessandro Giardino, Roberto Girelli, Isabella Frigerio, Paolo Regi, Maurizio Cantore, Auriemma Alessandra, Annita Lusenti, Roberto Salvia, Claudio Bassi, Paolo Pederzoli

Background: Radiofrequency ablation (RFA) is a relatively new technique, applied to metastatic solid tumours which, in recent studies, has been shown to be feasible and safe on locally advanced pancreatic carcinoma (LAPC). RFA can be combined with radio-chemotherapy (RCT) and intra-arterial plus systemic chemotherapy (IASC). The aim of this study was to investigate the impact on the prognosis of a multimodal approach to LAPC and define the best timing of RFA.
