This is a clinical trial to evaluate the intravenous administration of indocyanine green (ICG) as a method of intra-thoracic lesion localization. The primary purpose is to determine if intravenous ICG allows us to identify intra-thoracic lesions.

– This study is designed to determine the safety and feasibility of intra-operative localization of thoracic lesions following intravenous injection of indocyanine green (ICG), determine if intravenous ICG leads to the intra-operative detection of intra-thoracic lesions or metastatic lymph nodes not readily identifiable on conventional diagnostic imaging modalities, and determine if intravenous ICG improves surgical resection. – At the time of surgery, the indocyanine dye will be injected intravenously. The investigators will use a dose of 0.5 mg/kg administered prior to VATS. – The "filtered" near-infrared light causes the indocyanine green dye to fluoresce so that the surgeon can identify the lesions most likely to contain tumor cells.The surgeon will also look at lymph nodes to see if metastatic disease can be found in this location using this technique. The lymph nodes are processed to look for metastasis.
- Drug: ICG Intervention
- The intervention to be administered is the drug indocyanine green.
- Device: Near Infrared Camera
- The intervention to detect the administered drug, indocyanine green.
Arms, Groups and Cohorts
- Experimental: ICG Intervention
- The intervention to be administered is intravenous indocyanine green for intra-thoracic lesion localization and use of a near infrared camera to detect the ICG. All study subjects will receive this same intervention; there is only one arm.
Clinical Trial Outcome Measures
- Incidence of treatment-emergent adverse events (safety and feasibility) of intra-operative localization of thoracic lesions following intravenous injection of indocyanine green (ICG)
- Time Frame: 5 years
- In this initial proof-of-concept pilot trial for patients undergoing surgical resection of suspicious intra-thoracic lesions, the investigators will demonstrate that IV ICG is a safe and feasible method for lesion localization. The investigators will demonstrate this across a variety of intra-thoracic pathology including primary lung cancer, pulmonary metastases, mesothelioma, mediastinal tumors, and potentially infectious sources such as aspergilloma. The investigators will measure safety based on number of participants with treatment-related adverse events as assessed by CTCAE v4.0
- Determine if intravenous ICG leads to the intra-operative detection of intra-thoracic lesions or metastatic lymph nodes not readily identifiable on conventional diagnostic imaging modalities
- Time Frame: 5 years
- The investigators will determine if lesions can be identified that were not seen on pre-operative imaging either because they were too small, missed, or ill-defined. In addition, many lesions such as vague ground glass opacities, which could represent scarring or a slow growing bronchoalveolar cancer, may be targeted with IV ICG, and thus aiding in the decision to resect a given lesion. Lymph nodes that contain disease may also uptake IV ICG. If a lymphadenectomy is indicated for standard of care, NIR positive nodes will be noted.
- Determine if intravenous ICG improves surgical resection
- Time Frame: 5 years
- In cases of malignancy, performing an adequate oncologic resection (i.e. negative margins) or debulking is crucial to the prognosis of a patient with an intra-thoracic malignancy. Simultaneously, a surgeon must minimize the amount of resected healthy tissue to preserve lung function. Therefore, the investigators will assess the histologic status of the margin in all patients in which the lesion was ICG positive. The investigators will also maintain records of patients undergoing IV ICG to obtain intra-operative characteristics (i.e. successful lesion localization) and long-term events (i.e. local recurrence).
Participating in This Clinical Trial

- Subjects who do not wish to have subsequent surgical resection – A medical condition such as uncontrolled infection or cardiac disease that, in the opinion of the treating surgeon, makes resection unreasonably hazardous for the patient – Pre-operative spirometry that suggests the patient is at high risk or cannot undergo resection of the primary tumor. – Iodide or seafood allergy
