Popis: 9037 Background:Patients with very-high risk EFTs have a poor prognosis. Melphalan (L-PAM) has been widely used in myeloablative regimens in EFTs, without a prior demonstration of its effectiveness in this disease. Methods: From March 2001, a study was opened for very-high risk EFTs with the main aim to investigate the activity and toxicity of up-front L-PAM at non myeloablative doses. Treatment consisted of initial window-therapy with L-PAM (50 mg/m2 every 21 days × 2 courses) followed by 8 intensive chemotherapy courses, and consolidation with megatherapy+autologous PBSC rescue. PBSC collection was scheduled in responders after the 4th/6th chemotherapy course. Surgery and radiotherapy were employed on individual basis Results: As of September 2003, 17 consecutive patients (median age 16yrs, range 9–34) were enrolled. All patients were evaluable for toxicity and up-front L-PAM activity. No severe toxicities were reported, but for grade 3–4 hemopoietic toxicity. After L-PAM courses, grade 4 neutropenia, t...
