Stereotactic MRI-guided Adaptive Radiation Therapy (SMART) in One Fraction

Not Applicable
Completed
Conditions
Metastatic Carcinoma
Interventions
Radiation: Stereotactic ablative body radiation therapy
Registration Number
NCT04939246
Lead Sponsor
Baptist Health South Florida
Brief Summary

This is a multi-site single arm feasibility study of single-fraction Stereotactic MRI-guided Adaptive Radiation Therapy (SMART) for primary or metastatic carcinoma involving the lung, liver, adrenal gland, abdominal/pelvic lymph node, pancreas, and/or kidney. Stereotactic ablative body radiation therapy (SABR) is a highly-focused radiation treatment that gives an intense dose of radiation concentrated on a tumor, while limiting the dose to the surrounding organs.

GroupInterventionDescription
Single-fraction SABRStereotactic ablative body radiation therapyPatients will receive SABR in a single-fraction regiment treatment with one single dose of radiation therapy per lesion. Patients may be treated for up to a total of ten lesions. Each lesion will be treated in one fraction.
Primary Outcome Measures
NameTimeMethod
Number of SABR successfully delivered in one fractionthrough study completion, an average of 1 year

Number of SABRs that meet the following criteria:

1. Successful completed for each lesion within 3 days of intended treatment

2. Successful completion of treatment to each lesion within 90 minutes from the patient entering the treatment room until treatment completion

3. Image guidance verification of treatment delivery within 5 mm of the planned delivery

Number of patients demonstrating tolerabilitythrough study completion, an average of 1 year

Number of patients that meet the following criteria:

1. No greater than 4 of 30 patients experience grade 3 or higher acute toxicity within 90 days of completing SABR

2. No grade 5 toxicity is attributed to SABR

Secondary Outcome Measures
NameTimeMethod
Change in one-year local controlbaseline, up to 12 months after treatment

Change in one-year local control will be assessed according to RECIST 1.1 criteria and will be estimated using the Kaplan-Meier method along with the corresponding 95% confidence interval from the time of study treatment.

Change in participant reported quality of life questionnairebaseline, up to 12 months after treatment

Patient-reported quality of life will be determined using the FACT-G survey instrument. Fact-G is a 27-item questionnaire that covers four HR-QOL sub-domains: physical, social, emotional, and function well being. Each question will be scored from a scale from 0 (not at all) to 4 (very much) using a manual scoring template in which some items are reverse.

Number of participants with one-year overall survival12 months after treatment

Number of participants with one-year overall survival will be estimated using the Kaplan-Meier method along with the corresponding 95% confidence interval from the time of study treatment.

Proportion of participants with a change in acute and late toxicity resultsbaseline, during treatment, up to 12 months after treatment

Proportion of participants with a change in acute and late toxicity results who experience acute grade 3 or higher toxicity attributable to SABR will be determined along with the corresponding 95% confidence interval. For patients receiving SABR to multiple lesions, acute toxicity will be determined from the date of the initiation of SABR.
