Long-term survival in adult mediastinal neuroblastoma.

Neuroblastoma rarely occurs in adults, in whom prognosis is poor. Here we report on the effective use of multimodal therapy to achieve long-term survival in adult mediastinal neuroblastoma. In a 33-year-old male with severe pain radiating from the left hypochondrium to the back area, no abnormal shadow was detected on first examination; the shadow appeared in chest X-ray only 10 months later when the severe pain recurred. The patient was then referred to our department for further examination. Chest X-rays and chest CT scans revealed a posterior mediastinal mass beside the thoracic vertebrae. Diagnosis was confirmed after surgical resection, which was followed by outpatient adjuvant therapy through radiation and chemotherapy. The patient has survived 8 years and 8 months without recurrence or metastasis.
