Case Reports
Paclitaxel-induced remission in docetaxel-refractory anthracycline-pretreated metastatic breast cancer.
Paclitaxel and docetaxel are excellent agents with a high antitumor effect for the treatment of previously anthracycline-exposed metastatic breast cancer. There has been no standard treatment for patients who undergo therapy of a taxan-resistant metastatic breast cancer. Paclitaxel has partial non-cross-resistance in vitro with docetaxel in inhibiting microtubule disaggregation. We present the case of a patient with docetaxel-refractory anthracycline-pretreated metastatic breast cancer who achieved remission with paclitaxel.

Anaphylaxis or significant hypersensitivity reaction is one of the most catastrophic potential complications of chemotherapy. There is a 2-5% risk of hypersensitivity with paclitaxel, a commonly used chemotherapeutic agent for various cancers. Three patients, who developed hypersensitivity to paclitaxel infusion, received docetaxel without allergic reactions. Docetaxel may therefore be an alternative treatment for patients with paclitaxel hypersensitivity.
