摘要

pancoast%26apos;s s赤ndrome is produced by an apical lung tumor, with a local extensi車n to inferior brachial plexus, paravertebral sympathetic chain, vertebral bodies and first, second ans third ribs. its major cause is the non-small cell lung cancer, and this syndrome may produce shoulder pain and horner%26apos;s syndrome. the best diagnostic method is transthoracic needle aspiration, because of its peripheral location. neoadjuvant chemoradiotherapy followed by complete surgical excision is the preferred approach to these tumors.
