Evaluation of Outcome and Prognostic Factors in Thoracic Primitive Neuroectodermal Tumor: A Study of 84 Cases

This is a single-institutional experience of 84 patients with thoracic PNETs who underwent a uniform chemotherapy protocol. Novel prognostic factors were identified for thoracic PNET. All efforts should be made to resect primary tumor after neoadjuvant chemotherapy because radical RT results in inferior EFS and LCR despite good response to neoadjuvant chemotherapy.
