BACKGROUND: A 63-year-old man with therapy-resistant Sézary syndrome was enrolled in a multicenter trial of oral bexarotene for advanced-stage cutaneous T-cell lymphoma (CTCL).
METHODS: Monthly evaluations for efficacy and side-effects were conducted and documented.
RESULTS: Gradual improvement in erythema, pruritus, and scale was noted during the initial 16-week trial period and treatment was extended to 40 weeks. From week 20 to week 40, the erythroderma continued to improve and the lymph node burden decreased, but the absolute Sézary cell count inversely increased. By week 40, intractable pruritus and erythroderma abruptly recurred, and bexarotene was discontinued.
CONCLUSIONS: Bexarotene is well tolerated and can be efficacious in patients with Sézary syndrome. Shifting of Sézary cells between different compartments was noted. Further studies on the interaction between the skin, lymph nodes, and peripheral blood compartments during bexarotene treatment in this subset of patients with CTCL are needed.
