Individualized Lung Tumor Stereotactic Ablative Radiotherapy (iSABR)
Trial of Individualized Lung Tumor Stereotactic Ablative Radiotherapy (iSABR)
A research study of a procedure to treating lung cancer with focused radiation called Stereotactic Ablative Radiotherapy (SABR). The purpose of this study is to evaluate the effectiveness of individualizing the dose of radiation used to treat lung tumors with SABR based on tumor-specific factors.
While recent research has identified SABR as a promising method to increase local control (LC) of lung cancer, further research has indicated that tumor volume is a prognostic factor, with increased size/volume of tumor being associated with poorer outcomes. This study explores if a volume-adapted strategy for the radiologic exposure (dose) will improve efficacy in larger tumors (ie, > 10 cc).
This is a study of the procedure stereotactic ablative radiotherapy (SABR). It is not a study of a specific drug or device.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Evaluate Local Tumor Control with Individually-optimized Stereotactic Ablative Radiotherapy (SABR) for lung tumors.
Time Frame: 1 year
|
Tumor control will be assessed by CT, PET-CT, and if appropriate, biopsy.
Tumor control is defined as a determination that the participant has not experienced Local Failure at the treatment lesion, meaning primary tumor failure or involved lobe failure or both.
The outcome is reported as the number of participants who maintain tumor control for 1 year from the completion of Stereotactic Ablative Radiotherapy (SABR) treatment, a number without dispersion.

Time Frame |
---|---|---|
Toxicity of Individually-Optimized Stereotactic Ablative Radiotherapy (SABR) for Lung Tumors
Time Frame: 1 year
|
In concept, toxicity refers to adverse events caused by an intervention, ie, related adverse events. Toxicity will be assessed on the basis of related pulmonary; esophageal; chest wall; skin; vascular; cardiac/pericardial; and neurologic adverse events. Such events may have a number of different preferred terms for the adverse effect. The outcome will be reported as the number of Grade 3 or higher adverse effect events (toxicities), by Common Terminology Criteria for Adverse Events (CTCAE) Body System. The following exceptions apply.

Feasibility of Using an Optimized Breath-hold Technique during Stereotactic Ablative Radiotherapy (SABR) to Treat Lung Tumors
Time Frame: up to 2 years
|
Radiotherapeutic dose levels to the tumor lesion may be limited by the proximity of critical organs.
Reduced dose levels is believed to be associated with reduced therapeutic effect.
This study will assess an anatomically-optimized audio-visual biofeedback (AVB)-coached breath-hold technique assisted by fast radiotherapy delivery.
Holding breath at a particular point in the breathing cycle may minimize proximity between tumor lesions and critical organs.
In summary, participants will be coached to breath-hold at a certain point in their normal breathing cycle, and radiation will be quickly administered in bursts for several seconds.
Up to 12 to 15 cycles of breath-hold may be needed to administer the desired dose level.
Feasibility of this technique will be assessed as the number of patients able to reproduce the optimized breath-hold.
The outcome is a number without dispersion.

up to 2 years

Difference in Treatment Delivery Time Using an Optimized Breath-hold Technique
Time Frame: up to 2 years
|
Radiotherapeutic dose levels to the tumor lesion may be limited by the proximity of critical organs.
Reduced dose levels is believed to be associated with reduced therapeutic effect.
This study will assess an anatomically-optimized audio-visual biofeedback (AVB)-coached breath-hold technique assisted by fast radiotherapy delivery.
Holding breath at a particular point in the breathing cycle may minimize proximity between tumor lesions and critical organs.
In summary, participants will be coached to breath-hold at a certain point in their normal breathing cycle, and radiation will be quickly administered in bursts for several seconds.
Up to 12 to 15 cycles of breath-hold may be needed to administer the desired dose level.
Utility of this technique will be assessed as the difference in treatment delivery time compared to free-breathing treatment, reported as the median with standard deviation.

Progression-free survival (PFS)
Time Frame: up to 2 years
|
Progression-free survival (PFS) is a measure of participant survival without disease recurrence, relapse, metastasis, or progression.
The outcome is reported as the number of participants who were alive 2 years after the completion of Stereotactic Ablative Radiotherapy (SABR) treatment, and without disease progression during that time.
The outcome is a number without dispersion.

Metastasis-free Survival (MFS)
Time Frame: 2 years
|
Metastasis refers to the ability of cancer cells to break free of a tumor, and migrate to another location in the body and start a new tumor lesion.
Metastasis-free survival (MFS) is a measure of participant survival without disease metastasis.
The outcome is reported as the number of participants who were alive 2 years after the completion of Stereotactic Ablative Radiotherapy (SABR) treatment, and without documented metastasis in that time.
The outcome is a number without dispersion.

Overall Survival (OS)
Time Frame: 2 years
|
Overall survival (OS) is a measure of participant survival without regard to disease status.
The outcome is reported as the number of participants who were documented as alive 2 years after the completion of Stereotactic Ablative Radiotherapy (SABR) treatment.
The outcome is a number without dispersion.
