BACKGROUND: Posterior mediastinal neurogenic tumors are among the most frequent mediastinal masses in adults. These tumors may be dumbbell shaped, extending into the spinal canal, exclusively paraspinal or apical tumors extending in the cervical region. In this report, we present our experience in the surgical resection of these tumors and discuss the surgical strategies for such tumors. METHODS: A retrospective analysis was performed of 121 patients who underwent surgery for posterior mediastinal neurogenic tumors at our department during the period 2009 to 2016. Seventy-four tumors were excised via video-assisted thoracic surgery (VATS). Other approaches included thoracotomy, supraclavicular incision, supraclavicular incision plus thoracotomy/VATS, and a posterior approach with laminectomy combined with thoracotomy/VATS. RESULTS: Tumors were resected completely in 119 cases and partially in two. The majority of the tumors were benign nerve sheath tumors. No recurrence developed during postoperative median follow-up period of 31 months. CONCLUSION: Most posterior neurogenic tumors can be resected via VATS. Thoracotomy is the appropriate surgical approach for large tumors. A supraclavicular approach is recommended for tumors extending in the cervical region, and this can be combined with VATS or thoracotomy in case of larger masses. A posterior approach could be used for patients with dumbbell tumors.
