O'Leary et al. chemotherapy. These patients were able to maintain a remission without any further therapy. Hence, the Berkowitz-Goldstein regimen was widely adopted for non-metastatic GTD. Next, the Gynecologic Oncology Group (GOG) investigated the possibility of utilizing weekly single-agent MTX at a dose of 30 to 50 mg/m2 • Patients were treated until hCG levels had normalized for three consecutive weeks. This cost-effective and welltolerated regimen replaced the Berkowitz and Goldstein regimen as the standard of care for treating non-metastatic GTD.

These include: chemotherapy-induced tumor necrosis in the primary tumor, baseline LDH serum value, and use of high dose MTX [51]. Maximal dose intensification of doxorubicin and MTX have been considered as important determinants of outcome [52). In one institutional experience, in a multivariate analysis, the dose intensity ofMTX was the most important factor in predicting outcome in non-metastatic osteosarcoma [51, 53, 54). Others have found that cisplatin dose-intensity, but not MTX, improved results.

For this reason we have given added focus to pharmacological principles, and the use of high dose methotrexate. Uses of methotrexate Gestational trophoblastic disease In 1956, the introduction of methotrexate (MTX) to treat gestational trophoblastic disease (GTD) revolutionized the treatment and outcome of this disease. For non-metastatic GTD, the cure rate reached almost 100%. Prior to the introduction of chemotherapy, surgery with hysterectomy achieved a five-year survival of only 41 %. As such, surgery began to play a diminished role and was subsequently used only for initial evacuation of the mole.
