title: Osteogenic sarcoma: state of the art with high-dose methotrexate treatment.
abstract: The development and application of the VCR-MTX-CF regimens for the treatment of osteogenic sarcoma have changed the biological behavior of the tumor. Recent results strongly project major advances for the future. Although the major effect of chemotherapy resides in the eradication of micrometastases, its application for treatment of the primary tumor may also be considered. However, careful experimental design and follow-up periods for several years will be required to determine the optimum approaches. For example, it is possible that the interaction between weekly VCR-MTX-CF and radiation therapy may assume increasing importance. Thus, with the effective application of VRC-MTX-CF, the management of osteogenic sarcoma has evolved into a multidisciplinary approach and future advances will be based on the collective judgement of specialists from many fields.
