Purpose:
Cervicothoracic and apical thoracic neuroblastoma pose unique surgical challenges. We report our experience with the trapdoor anterior thoracotomy (TAT) approach to overcome these difficulties.
Methods:
Retrospective review of our centre's neuroblastoma database was conducted. Patients who underwent TAT at our centre were included, their demographic data and clinical reports were analyzed.
Results:
A total of 21 patients underwent TAT for neuroblastoma, mean age at surgery of 3.5 (0.3-7.9) years, male to female ratio was 11:10. Fifteen patients had cervicothoracic tumors while 6 had apical thoracic tumors. All except 2 were primary tumors. They were stage M (n = 12), MS (n = 1), and L2 (n = 8). At pre-operative assessment, 19 patients had image-defined risk factor (IDRF), including dual compartmental involvement (n = 15), trachea/bronchus compression (n = 4), encasement of carotid (n = 5), subclavian (n = 11), and vertebral arteries (n = 6). Four underwent upfront surgery while 17 received pre-operative chemotherapy of 2-8 (mean 3.9) cycles. All patients accomplished gross total resection. None had MYCN amplification. The postoperative complications included Horner's syndrome (n = 21), Klumpke's palsy (n = 1), winged scapula (n = 1), phrenic nerve palsy (n = 1), and bronchomalacia (n = 2).
Conclusion:
Gross total resection of cervicothoracic and apical thoracic neuroblastoma can be accomplished by TAT with minimal morbidity.
