title: High serum lactate dehydrogenase level predicts short survival after vincristine-doxorubicin-dexamethasone (VAD) salvage for refractory multiple myeloma.
abstract: We evaluated possible prognostic factors just before salvage therapy with vincristine, doxorubicin, and dexamethasone (VAD) for 36 patients with refractory multiple myeloma. The median duration from diagnosis to the first VAD salvage was 14 months (range 2-76 months). Among parameters that have been shown to be associated with poor survival, a high serum lactate dehydrogenase (LDH) level was the sole significant predictor of survival. The median survival of patients with high LDH levels was 4 months, whereas that of patients with low LDH levels was 20 months. A multivariate analysis identified high LDH and high age as independent prognostic factors. More aggressive therapies might be indicated for high-LDH patients with refractory myeloma.
