Abstrakt:	Prior to the development of en bloc techniques, vertebral invasion by non-small cell lung cancer (NSCLC) had been considered a relative contraindication to surgical intervention. However, reports in the literature have demonstrated increased progression-free survival with the use of neoadjuvant chemotherapy followed by anterior en bloc resection of the residual tumor. Stereotactic spine navigation has been shown to improve accuracy during complex vertebral osteotomies, improving patient outcomes. We report a 53-year-old woman with an NSCLC in the left upper lobe, a periosteum attachment of the second and third thoracic vertebrae (T2 and T3, respectively), and an infiltration of the corresponding nerve roots. We describe a surgical approach for the resection of NSCLC with vertebral infiltration utilizing stereotactic spine navigation and intraoperative computed tomography (CT) (O-Arm, Medtronic, Minneapolis, Minnesota, US) for a posterior approach laminectomy, osteotomy, and partial vertebrectomy, followed by trans-thoracic en bloc resection of a superior pulmonary sulcus tumor with nerve root infiltration. Posterior approach vertebral osteotomy and en bloc resection for superior sulcus NSCLC infiltrating the vertebrae utilizing stereotactic spine navigation and intraoperative CT (O-Arm) is a viable alternative to the traditional anterior approach.
