Overveiw
Other diagnostic studies for evaluating the spread of Pancoast tumor include bone scintigraphy, PET scan, molecular tests and biopsy.
Other Diagnostic Studies
Other diagnostic studies for evaluating the spread of Pancoast tumor include pulmonary angiography, molecular tests and biopsy.
Pulmonary Angiography
- On pulmonary angiography, findings of Pancoast tumor may be used for:[1]
- Evaluation of central pulmonary artery invasion
Molecular Test
Molecular tests include epidermal growth factor receptor (EGFR) mutation and anaplastic lymphoma kinase (ALK) mutation. Specific targeted agents may be administered to patients if these mutations are present. A transthoracic needle biopsy and a bronchoscopy are conducted to diagnose lung cancer.
Biopsy
A transthoracic needle biopsy, guided by CT or fluoroscopy, is for pancoast tumors located in the periphery of the lungs since peripheral tumors are not accessible through a bronchoscope.
