[An Undeniable Case of Optic Neuropathy Due to Cabazitaxel].
Cabazitaxelis a taxane-type antineoplastic agent used for treating prostate cancer. Although typical side effects include neutropenia and fatigue, no studies have investigated eye disorders as a possible side effect, and the details are not clear. Herein, we report our experience of an undeniable case of optic neuropathy caused by cabazitaxel. A 78-year-old man had been diagnosed with prostate cancer (cT3aN1M1b, stage IV) 3 years previously, with a treatment history of bicalutamide, leuprorelin, flutamide, docetaxel, abiraterone, and enzalutamide. Because of a decline in vision during the second and third administration cycles of cabazitaxel, the patient visited an ophthalmologist. He was found to have reduced visual acuity, reduced central critical flicker frequency, narrowed field of vision, and impaired color vision, and was diagnosed with optic neuropathy. Although cabazitaxel administration was continued through 6 cycles, the symptoms were unchanged, and no drastic exacerbation was seen. This patient undeniably developed optic neuropathy due to cabazitaxel. Optic neuropathy due to taxane-type antineoplastic agents has also been reported with paclitaxel or docetaxel, and all precautions should be taken when administering such drugs. Detailed studies that include data from a larger number of facilities should be conducted in the future.
