Optic Nerve Metastasis from Breast Carcinoma after Treatment with Taxanes

Le résumé fourni par la source

Introduction: The incidence of ocular metastasis from Breast Carcinoma is only between 5% - 30%, mainly located in choroid, but the location in optic nerve is even more infrequent. We present a rare case that combined both locations sequentially in the same eye. Methods: Case report. Results: A 58-year-old woman with advanced breast cancer was referred with a choroidal metastasis in her right eye which responded well to systemic Taxol and Avastin. Afterwards, she developed an optic nerve metastasis in the same eye when she was under the treatment, so it was changed to Docetaxel. Unfortunately the patient didn’t respond to this treatment and died. Conclusions: Choroidal metastasis secondary to breast cancer generally responds well to radiotherapy. Even so, in cases that a great deterioration of visual acuity is expected after radiation, chemotherapy like taxanes is an alternative to preserve vision with complete tumor regression. Nevertheless, the presentation of a second metastasis in optic nerve can be indicative of inadequate treatment of metastatic disease or complication of the treatment, or both.
