Oh et al. report on the use of the multikinase inhibitor sorafenib in a panel of prostate cancer cell lines and their derivatives which mimic endocrine and chemotherapy resistance. They demonstrate that the multi-targeting effects of sorafenib induces growth inhibition and apoptosis in a variety of prostate cancer cell lines. They also found that sorafenib affects AR expression and signalling. Their data suggest that maximal effect of sorafenib may be expected in androgen-sensitive prostate cancer prior to the development of resistance to castration and chemotherapy. They also show that there could be a rationale for the use of sorafenib in docetaxel-resistant carcinoma of the prostate.
The results of this study indicate that there is a potential to use sorafenib in prostate cancers as an adjuvant therapy option to current androgen ablation treatments, but also in progressed prostate cancers that become unresponsive to standard therapies.
