Non-clear cell renal cell carcinoma: does the mammalian target of rapamycin represent a rational therapeutic target?

ABSTRACT: Non-clear cell renal cell carcinomas (nccRCCs) comprise a heterogenous and poorly characterized group of tumor types for which few treatments have been approved. Although targeted therapies have become the cornerstones of systemic treatment for metastatic renal cell carcinoma, patients with nccRCC have been excluded from many pivotal clinical trials. As such, robust clinical evidence supporting the use of these agents in patients with nccRCC is lacking. Here, we review the disparate nccRCC subtypes, the criteria for diagnosis, and the prognoses associated with each subtype, in addition to evaluating the potential use of mammalian target of rapamycin (mTOR) inhibitors in treating patients with nccRCC. Both genetic analyses and preclinical research indicate a central role for mTOR in nccRCC;
