ObjectiveWe reviewed our 8-year experience with en bloc partial and total vertebrectomy for lung cancer invading the spine and report outcome and survival.MethodsNineteen patients with lung cancers involving the spine underwent en bloc resection. Eleven received induction treatment (chemotherapy, n = 5; chemoradiotherapy, n = 4; and radiation, n = 2). Pneumonectomy was performed in 3 patients, lobectomy in 13 patients, and wedge resection in 3 patients. Hemivertebrectomy was performed in 15 patients, and total vertebrectomy was performed in 4 patients. The median number of resected vertebral bodies was 3 (range, 1-4). Tumor stage was IIIB in 14 patients, IIIA in 1 patient, and IIB in 4 patients (hemivertebrectomy is performed in the case of T3 disease to obtain free margins). Surgical nodal status was N0 in 13 patients, N1 in 3 patients, N2 in 1 patient, and N3 (supraclavicular) in 2 patients. Complete macroscopic and microscopic resection was achieved in 15 (79%) patients.ResultsThere was no immediate postoperative mortality. Morbidity was observed in 10 patients, including 4 (21%) complications related to the spinal surgery. The median hospital stay was 30 days. Seven patients were alive after a mean follow-up of 26 months (range, 7-74 months). The 1- and 5-year predicted survivals (updated) are 59% and 14%, respectively. Nine local recurrences were observed.ConclusionsEn bloc resection of chest tumors with vertebrectomy is technically demanding, and postoperative morbidity should be critically addressed with this aggressive surgical intervention. However, an encouraging long-term survival observed in this series suggests that en bloc resection could be a valid option in selected patients with vertebral involvement of chest tumors.
