A Study of Stereotactic Radiosurgery (SRS) to Treat Pain in the Chest and/or Stomach Wall

January 15, 2026 updated by: Memorial Sloan Kettering Cancer Center

A Phase I Dose Escalation Trial for Treatment of Chronic Thoracoabdominal Wall Pain Through Ablation of the Dorsal Spinal Nerve Using Single-Fraction Stereotactic Radiosurgery

The researchers are doing this study to find out whether stereotactic radiosurgery (SRS) is a safe, practical (feasible), and effective treatment for people with chronic TAWP. The researchers will test different doses of SRS to find the highest dose that causes few or mild side effects.

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.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients must have a documented history of chronic (≥ 3 months) thoracoabdominal wall pain (TAWP) attributable to ≤ 3 unilateral spinal levels as confirmed by diagnostic paravertebral nerve block or TENS (if results of the paravertebral nerve block are inconclusive) performed by an attending anesthesiologist specializing in pain management prior to study enrollment.
  • Patients must have TAWP that is inadequately relieved by a trial of conventional pharmacologic therapy (defined as NRS pain score ≥ 4/10 while on treatment with conventional pharmacologic therapy for analgesia) as determined by an attending physician specializing in pain management.
  • KPS ≥ 60%
  • Age ≥ 18 years old

Exclusion Criteria:

  • Patients with a life expectancy of < 6 months as predicted by the Adult Comorbidity Index (ACE-27, see Appendix 1)
  • Patients with active autoimmune connective tissue disease
  • Patients with bilateral TAWP
  • Patients with preexisting pneumothorax
  • Patients with preexisting excessive pleural effusion (extending > 3 vertebral levels)
  • Systemic chemotherapy delivered or planned to be delivered within +/- 5 days of SRS
  • Unable to undergo a diagnostic paravertebral nerve block
  • Unable to undergo at least one of either a myelogram or spine MRI

  • Patients for whom external beam treatment plans to deliver the prescription SRS dose to the lesion of interest cannot be safely designed as specified by the Dose Constraint Guidelines in Appendix 2

    • Evaluation of any radiation doses previously delivered to spinal cord/cauda equina and other critical structures (bowel, esophagus, lungs, kidneys, rectum) will be taken into consideration
    • If radiation dose from SRS would exceed any normal tissue constraint as noted in Appendix 2, the patient will be ineligible

  • Abnormal complete blood count. Any of the following:

    • Platelet count < 75 K/µL
    • Hgb level < 9 g/dl
    • WBC < 3.5 K/µl
  • Abnormal coagulation profile: INR > 2.5 INR and/or APTT > 80 seconds. Patients who are on anticoagulation medication that may not be safely held for the myelogram procedure (≥ 5 days for antiplatelet agents and warfarin; ≥ 24 hours for low-molecular weight heparin formulations) will be excluded.
  • Allergy to local anesthestics
  • Local infection at the site of injection of anesthetic
  • Severe spinal deformities with anatomic distortion (severe scoliosis/kyphoscoliosis)
  • Severe respiratory disease (i.e. oxygen dependent)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
can be escalated from 70 Gy to 90 Gy without excessive DLTs
Time Frame: 2 years
DLT's CTCAE grade ≥ 3 toxicity. Acute and late toxicity will be assessed by investigators and graded according to the Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0. Toxicities that cannot be graded using the Common Toxicity Criteria will be graded as 1 (mildly symptomatic), 2 (moderately symptomatic but not interfering significantly with function), 3 (causing significant interference with function), or 4 (life-threatening).
