Low-dose thalidomide in combination with oral fludarabine and cyclophosphamide is ineffective in heavily pre-treated patients with chronic lymphocytic leukemia.
Elevated levels of TNF-alpha have been associated with progressive disease in patients with chronic lymphocytic leukemia (CLL). Thalidomide has been shown to inhibit production of TNF-alpha. We investigated the effects of thalidomide on clinical outcome and TNF-alpha serum levels in five pre-treated CLL patients. The schedule consisted on daily thalidomide (Thal), oral fludarabine (Flu) and oral cyclophosphamide (CTX). Median duration of treatment was 60 days; four patients stopped treatment for disease progression and one patient for neurological toxicity. Serum TNF-alpha levels did not show any decrease during treatment. Low-dose thalidomide is not effective in CLL patients with refractory disease.
