Management of thalidomide toxicity.
Thalidomide has re-emerged as a novel antineoplastic agent with immunomodulatory and antiangiogenic activities. In the early sixties, it was withdrawn from the market after its infamous association with congenital abnormalities that left about 10,000 children affected world-wide. With strict regulations and precautions, thalidomide is now approved by the FDA for the treatment of erythema nodosum leprosum. Its role in cancer therapy is promising, with clinical trials in the past 5 years showing significant activity in multiple myeloma. Several trials are ongoing in other malignancies, such as myelodysplastic syndrome, agnogenic myeloid metaplasia, renal cell carcinoma, and prostate cancer. The major toxicities of thalidomide are birth defects, sensorimotor peripheral neuropathy, somnolence, rash, fatigue, and constipation. Less common side effects include deep venous thrombosis, Stevens-Johnson syndrome, elevated liver enzymes, malaise, and peripheral edema. The incidence and severity of adverse events are related to dose and duration of therapy. Doses of the drug of 200 mg/day or less are usually well tolerated. In this review, we will discuss the incidence and management of the side effects of thalidomide and the precautions and interventions needed to minimize the toxicities of this drug.
