title: Methotrexate as relapse therapy for rhabdomyosarcoma.
abstract: Four patients had a local relapse after standard therapy for rhabdomyosarcoma and were treated with high-dose 42-hour MTX infusions. All patients responded to this therapy, one patient had a complete, and two patients a partial remission. Long duration MTX infusion should be part of a combination chemotherapy for relapsed rhabdomyosarcomas.
