Answer

Some researchers have suggested that all patients with Pancoast tumors should undergo ultrasonographic examination of the ipsilateral scalene area and that percutaneous biopsy should be performed on nodes with a transverse diameter greater than 1 cm. The purpose of these studies is to assist in staging of the disease. The use of a sector ultrasonographic unit with a supraclavicular approach has been useful in guiding needle aspirations,, with a yield for pathologic diagnosis in 91% of cases. [5, 14, 15]
