ARTICLE HIGHLIGHTS
Research background

Endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) is widely used to treat pancreatic cancer-associated pain. 

Research motivation

Response to the treatment of EUS-CPN is variable. 

Research objectives

To explore determinants of pain response in EUS-CPN for pancreatic cancer-associated pain.

Research methods

Univariable and multivariable logistic regression analyses were performed to explore predictors of pain response.

Research results

Invisible ganglia, metastatic disease, and invasion of the celiac plexus were identified as significant factors for a negative response to EUS-CPN. No severe adverse events were reported. 

Research conclusions

Invisible ganglia, distant metastasis, and invasion of the celiac plexus were predictors of less effective response in EUS-CPN for pancreatic cancer-related pain. For these patients, attention should be given regarding efficacy. 

Research perspectives

These findings could be helpful to endoscopists or oncologists to develop an appropriate treatment scheme for pain management in pancreatic cancer patients.
