Bronchoscopic Laser Ablation of Peripheral Lung Tumors
Bronchoscopic Laser Ablation of Solid Peripheral Lung Tumors Followed by Surgical Resection (BLAST-SR Trial)
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
PRIMARY OBJECTIVES:
I. To assess the pathologic changes that result from bronchoscopic laser ablation of peripheral lung tumors focusing on the proportion of complete tumor ablation.
SECONDARY OBJECTIVES:
I. To assess the safety of this technique by describing both procedure-related complications such as bleeding or pneumothorax and post-procedure adverse effects such as fever or pneumonitis.
II. To assess the pathologic changes observed in the lung tissue surrounding the treated lung tumor.
III. To assess radiographic changes observed by cone-beam computed tomography (CT) immediately after the application of bronchoscopic laser ablation.
OUTLINE:
Patients undergo bronchoscopic laser ablation following standard bronchoscopy and endobronchial ultrasound. Patients also undergo CBCT before and after laser ablation. 48-72 hours after the procedure, patients undergo standard surgical resection of the lung tumor.

Description
Inclusion Criteria:
- Written informed consent
- Performance status 0-2 (Eastern Cooperative Oncology Group classification)
- Subject is considered a candidate for bronchoscopy
- Subject is considered a candidate for surgery (other lobar or sub-lobar resection) based on radiographic staging and functional evaluation
- Lung lesion that is either biopsy-proven cancer or is suspicious for cancer
- Both non-small cell lung cancer (including carcinoid tumors) and metastatic disease
- The lesions should be: =< 3 cm, located in the outer 2/3 of the lung, and leave >= 1 cm of tumor-free lung parenchyma between target tumor and pleura or fissure
Exclusion Criteria:
- Tumors greater than 3 cm, located in the inner 1/3 of the lung, invading a major vessel, or located < 1 cm from the pleural or fissure
- Tumors qualified as non-resectable
- Tumors that cannot be reached bronchoscopically
- Patients declared non-surgical candidates
- Patients who are not candidates for bronchoscopy
- Patients with lung cancer who are found to have N2-3 disease
- Patient with lung metastases who are found to have any malignant mediastinal lymph node
- Patients in which the target lesion is confirmed as benign or small cell lung cancer
- Patients without a prior diagnosis of the target lesion whose diagnosis cannot be made during bronchoscopy
- Patients who have received chemotherapy within 60 days prior to bronchoscopic laser ablation
- Patients who were previously treated for the target lesion
- Pregnant patients

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pathologic Changes From Bronchoscopic Laser Ablation of Peripheral Lung Tumors
Time Frame: Up to 16 months
|
Pathologic changes will be categorized into three groups: 1. Complete Ablation: absence of staining (anti-mitochondria antibody [MAB] 1273 or nicotinamide adenine dinucleotide-hydrogen [NADH], or both) of tumor cells.
2. Quasi-Complete Ablation: positive staining of 10% of tumor cells.
3. Incomplete ablation: positive staining in > 10% of tumor cells.
Will conduct extensive descriptive analyses of the data collected.
Will calculate the appropriate summary statistics and 90% confidence intervals (CIs) for the measures of interest.
|
Up to 16 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Incidence of adverse events
Time Frame: Up to 2 years
|
Will be graded according to Common Terminology Criteria for Adverse Events (CTCAE).
Will be measured by serious adverse effects (SAE), defined as pneumothorax requiring chest tube, bleeding requiring balloon tamponade or leading to respiratory failure, and hypoxemia during bronchoscopy, post-bronchoscopy pneumonitis with need of supplemental oxygen.
|
Up to 2 years
|
Pathologic changes observed in the lung tissue surrounding the treated lung tumor
Time Frame: Up to 2 years

Will calculate the appropriate summary statistics and 90% CIs for the measures of interest.
|
At completion of bronchoscopic laser ablation
