Summary of Clinical Use Click here for help
Docetaxel is an anti-mitotic compound used mainly for the treatment of breast, ovarian, prostate, and non-small cell lung cancers.
Preliminary results from a recent clinical trial (June 2014) which compared hormone-depleting therapy alone with hormone-depleting therapy plus docetaxel in newly diagnosed metastatic prostate cancer patients, indicates that the combination treatment increases median survival after more than two years and delays cancer progression by around one year (unpublished results).
Mechanism Of Action and Pharmacodynamic Effects Click here for help
Docetaxel reversibly binds to microtubules with high affinity, hyper-stabilising their structure and limiting the flexibility of the cell's cytoskeleton, thus compromising cell growth, division and ultimately viability.
