Because patients with clear cell histology account for more than 80% of patients with RCC, little evidence is available on treating patients with non-clear cell histologies. Most clinical trials have excluded them from enrollment, except for a randomized study investigating temsirolimus. Many retrospective studies on the use of sunitinib, sorafenib, and temsirolimus in patients with non-clear cell histology have shown response rates ranging from 3.7% to 16%. Prospective studies in non-clear cell histologies are ongoing. Although response rates may not be as high as those in patients with clear cell histologies, targeted therapy may provide a clinically meaningful response. New investigational therapies are on the horizon for papillary RCC--the most-common non-clear cell RCC histology--targeting pathways specific to this histology, such as the c-MET pathway. | | Language | eng | | Pub Type(s) | Journal Article
