Summary : Advanced or metastatic renal carcinoma represents a frequent disease in oncologic practice. Few years ago, in immunotherapy era, treatments had quickly reached deadlock. New therapies targeting vascular endothelial growth factors and their receptors (VEGF-R), sorafenib, sunitinib and bevacizumab, and the mammalian target of rapamycin (mTOR), temsirolimus and everolimus, have modified these patients prognosis and their quality of life in a few years. Nevertheless, patients included in randomized trials presented severe inclusion criteria. Then in the daily practice, patients have distinctive characteristics which were not evaluated in large pivotal studies: poor performance status, older patients, renal dysfunction, cerebral metastases or non clear cell renal cancer. In published trials, a few data concerning these situations are reported, and these studies have often included small samples, were retrospective or not randomised. However compared to global population, tolerance have not been very different in geriatric patients, or patients with poor performance status, or with central neurological metastases, or with papillary and chromophobe sub-types. On the contrary progression free or overall survivals increases are more difficult to confirm. Also before starting treatment, ratio between potential benefit and possible toxicities have to be evaluated. In patients with renal insufficiency, VEGF receptor inhibitors seem to be cautiously initiated at reduced doses, and to be increased according to tolerance. Due to these poor proof levels, clinical trials are needed for these specific populations. |
