Prednisone pulse therapy for refractory myeloma

The utility of vindesine and a frequent prednisone schedule was evaluated in 70 patients with refractory myeloma. No patient responded to vindesine alone, but about one-fourth achieved significant tumor reductions from intermittent high-dose prednisone, either alone or in combination with vindesine. Forty-seven percent responded when prednisone pulses were combined with vincristine and doxorubicin, providing the best results yet achieved in our patients with refractory myeloma. In responding patients, remissions were of excellent quality and survival was prolonged significantly. These results supported the utility of a more frequent corticosteroid schedule with increased doxorubicin dose in patients with advanced and resistant multiple myeloma.
