En bloc partial vertebrectomy for lung cancer invading the spine after induction chemoradiotherapy

Objective: The optimal surgical treatment for non-small cell lung cancer (NSCLC) with vertebral body invasion remains both controversial and challenging. We reviewed our experiences of NSCLC with vertebral body invasion, in which we have performed induction chemoradiotherapy followed by lung resection with en bloc partial vertebrectomy. Methods: Six NSCLC patients with vertebral invasion underwent an operation following chemoradiotherapy from January 2001 to July 2006. Vertebral invasion was evaluated by the chest CT and MRI findings. Either carboplatin—paclitaxel(n = 3) or carboplatin—docetaxel(n = 3) was used.Twocyclesof chemotherapy wereperformedwith concurrent radiation (50 Gy) treatment. Results: In all of the six cases, a complete resection with en bloc partial vertebrectomy was performed with no operative mortality. The histological complete response rate and major response rate were 16.7% (1/6) and 83.3% (5/6), respectively. The 5-year overall survival rate was 67.7%. In addition, no local failure was observed after surgery. Conclusions: Surgery after chemoradiotherapy (carboplatin/ paclitaxel or docetaxel and 50 Gy radiation) for NSCLC with vertebral invasion could thus be performed with acceptable morbidity. # 2007 European Association for Cardio-Thoracic Surgery.
