title: Total spondylectomy for en bloc resection of lung cancer invading the chest wall and thoracic spine. Case report.
abstract: Lung cancers invading the chest wall and spinal column are often considered unresectable, and consequently there are few reports describing resection of invasive vertebral lesions. The authors developed a new anterior approach procedure for the en bloc resection of primary lung adenocarcinoma invading the thoracic spine and chest wall, in which the primary tumor does not need to be separated from the vertebrae. The authors describe a total spondylectomy for the en bloc resection of lung cancer invading the spine. A combination of surgical techniques was required, including resection of the osseous elements T-2 and T-3 (the pedicles were excised using a thread saw), anterolateral thoracotomy, apical lobectomy, chest wall resection, vertebrectomy, anterior spinal column reconstruction with a titanium mesh cage containing bioactive glass ceramic, and placement of anterior and posterior spinal instrumentation. At 46 months after surgery, there is no evidence of local recurrence or distant metastasis, and the patient continues to improve. This new procedure allows for the en bloc resection of primary lung tumors and adherent vertebral invasion without separation of the lesion from the vertebra. Thus, surgical management by complete excision of Pancoast tumors can achieve longer-term survival rates without sequelae.
