Thalidomide, a glutamic acid derivative, was withdrawn from clinical use in 1962 due to its severe teratogenic effects. Its recent reinstitution in clinical practice was related to its benefits in leprosy and multiple myeloma. Moreover, the antiangiogenic and immunomodulatory properties of thalidomide have led to its evaluation in several malignant diseases, including myelofibrosis, renal cell cancer, prostate cancer, and Kaposi sarcoma. However, thalidomide use is associated with several side effects: somnolence and constipation are the most common, while deep vein thrombosis and peripheral neuropathy are the most serious. A combination of thalidomide with steroids or chemotherapy is being evaluated in several phase 2 studies. While it is not yet clear whether these combinations will enhance efficacy, they appear to increase the toxicity of thalidomide, and thalidomide analogs are being developed to minimize this toxicity. Ongoing studies will clarify the potential advantages of these agents in the treatment of neoplastic diseases.
