[Pancoast tumor receiving preoperative concurrent chemoradiotherapy followed by radical resection via transmanubrial approach and posterior thoracotomy].

A 59-year old man complaining of right shoulder pain was diagnosed with Pancoast tumor. Chest computed tomography (CT) scan showed a right superior sulcus tumor, 5.8 cm in diameter, invading the middle-posterior compartment of thoracic inlet. Chest magnetic resonance imaging (MRI) sagittal section showed the possibility of infiltration to subclavian artery. The patient received preoperative concurrent chemoradiotyrapy (CCRT) [radiotherapy : 60 Gy/30 Fr, cisplatin and docetaxel], resulting in tumor regression (PR). The patient underwent right upper lobectomy and resection of the 1st- 2nd ribs and Th1 nerve via transmanubrial approach and high posterior thoracotomy. Pathological examination demonstrated a little live cancer cells and organization of necrotic tissue in the lung and inter costal region (Ef2). Transmanubrial osteomuscular sparing technique maintains an excellent exposure of thoracic inlet and cervical structures safely.
