Peripheral neuropathy secondary to docetaxel (Taxotere)

Docetaxel (Taxotere), a semisynthetic analogue of the antitumor agent paclitaxel, inhibits tubulin depolymerization. Paclitaxel produces a peripheral neuropathy. This study delineates clinically and electrophysiologically the characteristics of a peripheral neuropathy due to docetaxel. In 186 patients receiving docetaxel in phase I or phase II protocols, we performed serial neurologic exams, As patients became symptomatic, quantitative sensory testing and nerve conduction studies were done. Twenty-one patients developed mild to moderate sensory neuropathy on taxotere at a wide range of cumulative doses (50 to 750 mg/m(2)) and dose levels (10 to 115 mg/m(2)). Ten of these patients also developed weakness of varying degree in proximal and distal extremities. Nine of the 21 patients had received neurotoxic chemotherapy before; 16 were treated with docetaxel at a dose level of 100 to 115 mg/m(2). In summary, docetaxel produced a sensorimotor peripheral neuropathy in 11% of our patient population.
