Background and aims: Emerging data suggest neoadjuvant chemotherapy (NAC) for resectable pancreatic ductal adenocarcinoma (PDAC) is associated with improved survival. However, less than 40% demonstrate a meaningful radiographic response to NAC. Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) has emerged as a new modality to treat PDAC. We hypothesize that NAC plus EUS-RFA can be used in the management of resectable PDAC.
Methods: Prospective review of PDAC patients meeting criteria of resectable tumor anatomy that underwent NAC chemotherapy plus EUS-RFA followed by pancreatic resection. Radiographic imaging, perioperative and short-term outcomes were recorded. Surgical pathology specimens were analyzed for treatment response.
Results: Three eligible patients with resectable PDAC received 4 months of NAC plus EUS-RFA. One month after NAC and EUS-RFA completion, all 3 patients underwent standard pancreaticoduodenectomy without complications. After a 6-week recovery, all patients completed 2 months of post-op adjuvant chemotherapy.
Conclusions: In our institutional experience, this treatment protocol appears safe as patients tolerated the combination of chemotherapy and ablation. Patients underwent pancreatic resection with uneventful recovery. This novel neoadjuvant approach may provide a more effective alternative to chemotherapy alone.
