Definition/Description[edit | edit source]
Pancoast tumor is an uncommon lung cancer that arises at the level of the superior sulcus and is limited to the apical segment of either lung. This is a form of non-small-cell carcinomas (NSCLCs) that are very difficult to treat because of their proximity and frequent metastisis to adjactent structures such as the subclavian vessels, lymphatic system, brachial plexus, spine, second and third ribs, stellate ganglion, and the sympathetic nervous system. Of the NSCLCs, they are divided into three different forms of cancer: squamous cell carcinomas (45-50%), adenocarcinomas (36-38%), or undifferentiated large-cell carcinomas (11-13%). Rather than invading underlying lung tissue, this tumor presents as a abnormal patch of tissue over the lung apex and initially involves the chest wall strucutures. This can be treated if caught early on before it spreads and moves to the lymph nodes. Pancoast tumors are often mis-diagnosed and/or diagnosed to late.
