The Role of Methotrexate in Osteosarcoma

Abstract

High-dose methotrexate (MTX) is one of the agents currently used in intensive adjuvant chemotherapy regimens for nonmetastatic osteosarcoma. To elucidate the role of high-dose MTX in this disease, we present the history of trials conducted with MTX from the first single-agent studies through progressively complex combination regimens. With this background, some of the basic dissues concerning MTX therapy in osteosarcoma are discussed. [J Natl Cancer Inst 1988;80:626–656]
