Phantom limb pain as a manifestation of paclitaxel neurotoxicity

Paclitaxel is a chemotherapeutic agent with activity directed against several malignancies. It has multiple adverse effects including neurotoxicity. We describe 2 patients with prior amputation who experienced phantom limb pain (PLP) after receiving paclitaxel therapy. A third patient experienced disabling neurotoxicity in the extremity of a prior ulnar nerve and tendon transposition after receiving paclitaxel. This unique syndrome should be identified as a direct causal effect of paclitaxel. In this report, we review the pathophysiology of PLP and treatment options. Physicians should be aware that PLP can occur after initiation of paclitaxel.
