Long-term Survival After Salvage Surgery for a Giant Primary Rib Osteosarcoma

A 29-year-old woman with a primary rib osteosarcoma declined treatment and was readmitted 20 months later in life-threatening condition caused by major local tumor progression with severe mediastinal shifting, and without distant metastases. She underwent extended tumor resection with palliative intent and recovered well after a prolonged course with post-pneumonectomy empyema. Further treatment was declined, and she presented again 4.5 years later with local chest wall recurrence that was completely resected. Currently, 7 years after diagnosis, the patient is free from disease. In this rare case, salvage surgery was associated with an unexpected favorable long-term outcome.
