Increased serum tumor necrosis factor α levels in patients with lenalidomide-induced hypothyroidism

As the use of lenalidomide expands, the poorly understood phenomenon of lenalidomide-induced thyroid abnormalities will increase. In this study we compared rates of therapy-induced hypothyroidism in 329 patients with DLBCL treated with conventional chemotherapy (DLBCL-c) or conventional chemotherapy plus lenalidomide (DLBCL-len). We measured serum levels of tumor necrosis factor alpha (TNF-α), interferon gamma (IFN-γ), interleukin-6 (IL-6), interleukin-12 (IL-12), and interleukin-15 (IL-15) before and after treatment. We found a significantly higher rate of therapy-induced hypothyroidism in the DLBCL-len group (25.8% vs 1.3%), and we found a statistically significant increase in serum TNF-α in patients with lenalidomide-induced hypothyroidism
