Abstract

We have updated the results of an adjuvant chemotherapy study of 106 patients with osteosarcoma of the extremities published 17 years ago, treated by surgery followed by adjuvant chemotherapy with vincristine (VCR), methotrexate (MTX) and doxorubicin (ADM), between 1980-1983, and followed-up for at least 20 years (20-23 years). In comparison with the results reported 17 years ago with a median follow-up of 38 months (range: 27-66), this updated study showed 24 more deaths, 9 more relapses and 3 second malignancies. Consequently, event-free survival (EFS) and overall survival (OS) are significantly lower compared to the previous study with a 3-year follow up (EFS 38% vs 53%; OS 43.8% vs 67%). We conclude that osteosarcoma patients treated with chemotherapy are at risk of late adverse events. Protracted medical follow-up and long-term updated results are useful to identify, at an early stage, late relapses and late treatment-related complications.
