Predictors of analgesic efficacy of neurolytic celiac plexus block in patients with unresectable pancreatic cancer: the importance of timing

Background Neurolytic celiac plexus block (NCPB) is a safe and effective method for reducing abdominal cancer pain. However, the analgesic efficacy of NCPB is not always guaranteed. The aim of this retrospective study was to identify predictors for the analgesic efficacy of NCPB in patients with unresectable pancreatic cancer.
