Funded by a Specialized Program of Research Excellence (SPORE) award from the National Cancer Institute (NCI), the Kidney Cancer Program (KCP) at UT Southwestern’s Harold C. Simmons Comprehensive Cancer Center reports the largest and most diverse catalog of kidney cancer tumor models to date. Kidney cancer is the eighth most frequently diagnosed cancer in the U.S. Despite the development of new drugs to treat kidney cancer, it remains largely incurable when metastatic. Most Food and Drug Administration-approved drugs were developed to treat clear cell renal cell carcinoma, the most common form of kidney cancer, but there are more than a dozen other types. Drug development for less frequent types has been limited by a lack of animal models suitable for preclinical studies.
