Initial Adjuvant Therapy in Advanced Squamous Cell Carcinoma of the Head and Neck Employing Weekly High Dose Methotrexate with Leucovorin Rescue

Our initial experience with weekly high dose methotrexate with leucovorin rescue (MTX-LCV), in advanced recurrent or metastatic squamous cell carcinoma of the head and neck with a 77% tumor response rate and high therapeutic index, prompted a trial of MTX-LCV as initial adjuvant therapy in high risk nonmetastatic patients. Results in 11 patients are presented and confirm the high response rate to MTX-LCV and the low incidence of myelotoxicity and mucositis, when concurrent urinary alkalinization is employed. Initial MTX-LCV administrations has not compromised subsequent optimum aggressive combinations of surgery and radiation therapy. Cytoreduction with MTX-LCV may be safely used initially in combined therapy for high risk squamous cell carcinoma of the head and neck.
