## Abstract ## Background With the introduction of intensive high‐dose chemotherapy for the treatment of osteosarcoma, changes in the pattern of metastases observed at relapse have been reported. To further investigate this hypothesis, the relapse patterns among groups receiving chemotherapy regimens of variable intensity at Memorial Sloan‐Kettering Cancer Center were analyzed. ## Procedure All patients treated with the protocols T4, T5, T7, T10, and T12 were included. Patients were divided into two groups, one including those patients treated with less intense therapy (T4, T5, and T7) and the other, those treated with current regimens (T10 and T12). ## Results Of the 25 patients who relapsed on the earlier protocols, 76% relapsed to the lungs, 8% had local recurrences, and 16% distant metastases to the bone. The median time to first relapse was 12 months. Of the 69 patients who relapsed on the T10 and T12 protocols, 75% relapsed in the lungs, 9% had local recurrences, and 16% distant bone metastases. The median time to first relapse was 17 months. There was no statistically significant difference in the timing of relapse between the two groups studied, although a longer median tim
