title: Chemotherapy-induced parkinsonism responsive to levodopa: an underrecognized entity.
abstract: Parkinsonism is a rare neurological complication of cancer treatment. Although individual case reports of this syndrome have been reported, the clinical features and prevalence of this syndrome are unknown. We present 3 patients, encountered over 6 months at one institution, who developed parkinsonism after treatment with various chemotherapeutic agents. Parkinsonism was severe in 2 patients, affecting postural reflexes, speech, and swallowing. All 3 patients responded dramatically to treatment with levodopa, and parkinsonism spontaneously improved or remitted over months. This unusual complication of cancer therapy is treatable and may be underappreciated.
