SORCE

A multi-centre phase III double-blind placebo-controlled study designed to examine the efficacy and tolerability of sorafenib (Nexavar) in patients with resected (total or partial) primary renal cell carcinoma (RCC) at high or intermediate risk of relapse

Can a tablet called Sorafenib stop kidney cancer coming back and how long should Sorafenib be taken for?

What was this study about?

Each year there are over 200,000 cases of kidney cancer. Surgery to remove a kidney or part of a kidney is usually the best treatment for kidney cancer. Although this often works, the cancer returns in 30-50% of patients.

The SORCE study was designed to discover whether taking a drug called sorafenib after the operation can reduce the risk of kidney cancer returning. We hoped that if sorafenib reduced the risk of kidney cancer returning, that it would also help patients live longer.

What difference did this study make?

The SORCE trial found no benefit for treatment with sorafenib, whether it was given for three years or one year. The results have been presented at an international medical conference and will be published in the Journal of Clinical Oncology, a peer-reviewed medical journal.
