Vibration Response Imaging (VRI) in Patients Who Are Potential Candidates for Surgical Resection

February 8, 2011 updated by: Deep Breeze

The primary purpose of the study is to investigate the use of VRI to guide the selection of patients for lung surgery. Perfusion scintigraphy is the current method to assess the fractional contribution of lung function of the remaining lung.

The hypothesis is that VRI can determine quantitative postoperative lung function equally accurately as a quantitative perfusion scan.

Detailed Description

Primarily, VRI will be compared to perfusion (Q) scan by predicted post-operative (ppo) FEV1 and DLCO as predicted by VRI versus as predicted by Q scan. Secondary, the ppo as predicted by each test will be compared with the actual FEV1 and DLCO at 3 months post-operative; If these two methods provide similar results, VRI will be deemed an acceptable alternative to Q scan for determining patient selection for lung resection. Finally, the patient outcomes (30 day mortality and pulmonary complications) for those patients falling within guideline parameters using the VRI measurement will be analyzed to see if using VRI in clinical practice would indeed allow prediction of satisfactory results (similar to literature benchmarks).

Sampling Method

Probability Sample

Study Population

Study participants will be patients who are candidates for lung resection (lobectomy or greater)

Description

Inclusion Criteria:

  1. Able and willing to read, understand, and provide written Informed Consent;
  2. Age range of 18-90 years;
  3. Potential candidate for at least lobectomy due to lung cancer or other intrathoracic malignancy (either suspected or proven by biopsy). Both open and minimally invasive (thoracoscopic) resections are acceptable.
  4. BMI > 19.

Exclusion Criteria:

  1. Body habitus or skin condition that might prevent the placement of the sound sensors on the back (e.g. severe scoliosis, kyphosis, chest wall deformation, skin lesion on the back or compression fracture);
  2. There should be no active pulmonary infection (e.g. pneumonia) at the time of the recordings;
  3. Hirsutism unless patient is willing to have back shaved;
  4. Potentially contagious skin lesion on the back;
  5. Giant bulla (more than 1/3 of the hemithorax or >10cm)
  6. Pregnant women

Design Details

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Lung resection candidates
Study participants will be patients who are candidates for lung resection (lobectomy or greater)
Procedure: Lung resection surgery
The study is designed in a way that will not alter the surgeon's decision based on routine assessment of candidates for resection (lobectomy or greater). Namely, the VRI data will be gathered prospectively; however, the analyses using VRI data will be performed retrospectively.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
Comparison of ppo FEV1 and ppo DLCO as predicted by VRI with the values as predicted by Q scan
Time Frame: Prior to surgery
Prior to surgery

Secondary Outcome Measures

Outcome Measure
Time Frame
Comparison of ppo as predicted by each test with the actual FEV1 and DLCO at 3 months post-operative
Time Frame: 3 months after surgery
3 months after surgery
