Abstract

Background/purpose: For pediatric tumors of the cervicothoracic junction, an isolated cervical or thoracic surgical approach provides insufficient exposure for achieving complete resection. We retrospectively examined "trap-door" and "clamshell" pediatric thoracotomies as a surgical approach to these tumors.

Methods: We searched our database for pediatric patients with cervicothoracic tumors who underwent clamshell or trap-door thoracotomy between 1991 and 2013, reviewing tumor characteristics, surgical technique, completeness of resection, morbidity, and outcome.

Results: Trap-door (n=13) and clamshell (n=4) thoracotomies were performed for neuroblastoma (n=9), non-rhabdomyosarcoma soft tissue sarcoma (n=4), germ cell tumor (n=2), rhabdomyosarcoma (n=1), and neuroendocrine small cell carcinoma (n=1). Fourteen of these cervicothoracic tumors were primary, and three were metastatic. Gross total resection was achieved in 15 patients (94%). Operative complications included vocal cord paralysis (n=2), mild upper-extremity neuropraxia (n=2), and hemidiaphragm paralysis (n=1), All but one involved encased nerves. Overall survival was 61% for the series and 80% for patients with primary tumors. Eleven (73%) of 15 patients who underwent gross total resection had no evidence of recurrence. Three patients with metastatic disease died of distant progression within 1.3years.

Conclusions: Gross total resection of primary cervicothoracic tumors can be accomplished with specialized exposure in pediatric patients with minimal morbidity.
