Abstract

PURPOSE:

Celiac plexus neurolysis (CPN) is currently used as salvage therapy for morphine-resistant pancreatic cancer pain. Endoscopic ultrasound-guided CPN (EUS-CPN) can be performed early, at the time of EUS. We hypothesized that early EUS-CPN would reduce pain and morphine consumption, increase quality of life (QOL), and prolong survival.

PATIENTS AND METHODS:

Patients were eligible if referred for EUS for suspected pancreatic cancer with related pain. If EUS and EUS-guided fine-needle aspiration cytology confirmed inoperable adenocarcinoma, patients were randomly assigned to early EUS-CPN or conventional pain management. Pain scores (7-point Likert scale), morphine equivalent consumption, and QOL scores (Digestive Disease Questionnaire-15) were assessed at 1 and 3 months.

RESULTS:

Five hundred eighty eligible patients were seen between April 2006 and December 2008. Ninety-six patients were randomly assigned (48 patients per study arm). Pain relief was greater in the EUS-CPN group at 1 month and significantly greater at 3 months (difference in mean percent change in pain score = -28.9 [95% CI, -67.0 to 2.8], P = .09, and -60.7 [95% CI, -86.6 to -25.5], P = .01, respectively). Morphine consumption was similar in both groups at 1 month (difference in mean change in morphine consumption = -1.0 [95% CI, -47.7 to 49.2], P = .99), but tended toward lower consumption at 3 months in the neurolysis group (difference in mean change in morphine consumption = -49.5 [95% CI, -127.5 to 7.0], P = .10). There was no effect on QOL or survival.

CONCLUSION:

Early EUS-CPN reduces pain and may moderate morphine consumption in patients with painful, inoperable pancreatic adenocarcinoma. EUS-CPN can be considered in all such patients at the time of diagnostic and staging EUS.
