| Hemoptysis Malignant Neoplasm Lung Cancer | Procedure: Technicium 99 MAA infusion | Not Applicable |
This study is a prospective, single-arm pilot study for patients presenting with hemoptysis from lung cancers. Prior to a therapeutic bronchial artery embolization (standard therapy), Tc99m-MAA will be administered to the bronchial artery and an imaging will be obtained to determine the distribution of MAA.
The primary objective will be quantification of Tc99m-MAA uptake within the tumor and surrounding structures (esophagus, bronchi, pericardium, spine). This is a purely descriptive study and no statistical comparison or correlation will be made. Dosimetry will be reported for each patient, as well as range and mean with standard deviation. Additional activity calculation methods and reporting metrics may additionally be used. Non-statistical comparison will be made to literature-reported external-beam radiation dose-related tumor response and adjacent-organ toxicities to develop a preliminary assessment of the potential for efficacy and anticipated safety-profile of Yittrium-90 bronchial artery radio-embolization.

Experimental: Technicium 99 MAA
Participants will receive bronchial artery administration of Technicium 99 MAA
|
Procedure: Technicium 99 MAA infusion
4mci of Technicium 99 MAA will be infused into the bronchial artery via a catheter prior to a standard therapy (bronchial artery embolization). The patient will undergo nuclear medicine imaging following this intervention to quantify MAA distribution within the lung tumor and adjacent lung tissue. |
- Quantification of Tc99m-MAA uptake [ Time Frame: 12 months ]The primary objective will be quantification of Tc99m-MAA uptake (measured in "Gray") within the tumor and surrounding structures (esophagus, bronchi, pericardium, spine). This is a purely descriptive study and no statistical comparison or correlation will be made. This assessment will be done for each participant at 12 months.
