Combined therapy for patients with mycosis fungoides.

In a comprehensive mycosis fungoides program, 60 patients have been seen with a pathologic diagnosis of this disease. Forty-four patients with advanced disease were referred for radiation therapy. Three treatment techniques were identified in which 14 patients were treated with localized fields using electrons or whole-body electron-beam therapy with doses of less than 3000 rads, 21 patients were treated using the Stanford technique with tissue doses of between 3000 and 4000 rads, and nine patients were treated with six cycles of mechlorethamine, vincristine, prednisone, and procarbazine or cyclophosphamide, vincristine, prednisone, and procarbazine following the electron-beam therapy. The actuarial survival rate was 45% at 1 year for the 14 patients with localized electron-beam therapy, whereas the actuarial survival rates were 83% for patients treated with whole-body electron-beam therapy and 100% for patients treated with whole-body electron-beam therapy followed by four-drug chemotherapy. The recurrence-free interval for these three groups correlates with these observations. A central nervous system recurrence has been observed in the combined-therapy group.
