title: High-dose methotrexate with citrovorum factor in osteogenic sarcoma--progress report II.
abstract: Vincristine (VCR), high-dose methotrexate (MTX), and citrovorum factor (CF) were administered to 12 patients with classic osteogenic sarcoma with local control. Seven patients (58%) are free of pulmonary metastases for 2+-31/2+ years. With a second adjuvant program incorporating adriamycin (VCR, MTX, CF, and adriamycin), 16 of 20 patients are free of pulmonary metastases for 6+-18+ months. Five patients who developed pulmonary metastases were rendered free of disease by surgical resection. The VCR, MTX, and CF program was also administered at weekly intervals to eight patients with pulmonary metastases or unresected primary lesions. Two complete and one partial response were obtained in four patients with pulmonary metastases and three complete and one partial response were obtained in patients with primary lesions. This program was also administered in combination with radiation therapy to four patients who relapsed on conventional VCR, MTX, CF, and adriamycin therapy following surgical resection of pulmonary metastases. They remain free of recurrent disease for 2+-14+ months. There was no alteration in the incidence of toxicity when compared to earlier investigations. The results indicate that the VCR, MTX, and CF program has had a major impact on the management of osteogenic sarcoma.
