Endoscopic Ultrasound Guided Coeliac Plexus Neurolysis for Cancer Pain

March 17, 2021 updated by: Dr. Ma Ka Wing, The University of Hong Kong

Endoscopic Ultrasound-Guided Coeliac Plexus Neurolysis for Cancer Pain: Chemical Versus Radiofrequency Ablation

Many cancer patients suffer from intractable pain and which is often suboptimally controlled by even strong opioid analgesics. Coeliac plexus neurolysis (CPN) is procedure which intended to permanently destroy the nociceptive pathway that transmits the pain caused by the tumour. It can be with different approaches, such as percutaneously guided by fluoroscopy, echo-endoscopically or surgically with endoscopic approach being the more popular one in many centers equipped with echo-endoscopic services. The effect of CPN has been well established by some retrospective series. The overall response rate to CPN ranges from 70-90%, however, the analgesic effect is limited and up to roughly around 3 months. It is believed that the short-lasting analgesic effect is related to incomplete neurolysis by absolute alcohol injection.

Recently, radiofrequency ablation (RFA) of coeliac plexus has been introduced as another mode of CPN. So far, only one small single center randomized controlled trial (RCT) suggesting superior performance in favour to CPN using RFA. This result has to be validated and by a RCT with larger sample size. In addition, data concerning the quality of life (QOL) improvement and cost-effectiveness need to be further elucidated. Therefore, the aim of this study is to perform a RCT to look into these issues.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The aim of this study is to compare the efficacy of EUS-CPN by chemical ablation using alcohol injection versus by radiofrequency ablation in patients with cancer pain related to intra-abdominal malignancy. This is a randomised controlled trial to assess the clinical outcomes and cost-effectiveness of this new treatment approach.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  • Age ≥18 year-old
  • Patients who give informed consent to the study
  • Suboptimal pain control with regular analgesics
  • Inoperable cancer of pancreas, biliary system and liver (both primary or secondary)

Exclusion Criteria:
