Abstract:
The use of carbonic anhydrase IX as a promising molecular marker in RCC is described by authors from Los Angeles, who discuss the promise that molecular markers hold to improve diagnosis, staging, treatment, surveillance and survival of patients with RCC. There is a whole range of new treatments being introduced in the management of metastatic renal cancer. The use of VEGF-targeted therapy has particular importance, especially as it has a strong genetically linked rationale for its potential success in this area. Authors from the USA show that substantial clinical activity has been reported in initial clinical trials. In prostate cancer, drugs targeting microtubules, such as taxanes, have already been introduced clinically, and their success has received widespread attention. A new group of drugs, the epothilones, have similar but not identical binding properties to microtubules, and authors from the USA describe how they have shown activity in hormone-refractory prostate cancer, and are moving to phase III testing.
