Advanced renal cell carcinoma (RCC) is a heterogeneous disease with variable histology, biology, and response to treatment. In the past 5 years, 6 new agents have been approved for the treatment of RCC, and many more are in clinical development. With an ever-increasing number of treatment options, selecting among them for a particular patient can be a daunting task for clinicians. This article describes how treatment choice can be guided by the disease setting and histology, as well as patient characteristics, comorbidities, and preference within the context of available data. Results from clinical trials are combined with practical considerations to make recommendations for first-line and subsequent treatment of patients with clear cell and non-clear cell RCC. These recommendations should supplement the current NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for the treatment of advanced RCC.

The outcome of patients with metastatic renal cell carcinoma has been substantially improved with administration of the currently available molecularly targeted therapies. However, proper selection of therapy and management of toxicities remain challenging. NCCN convened a multidisciplinary task force panel to address the clinical issues associated with these therapies in attempt to help practicing oncologists optimize patient outcomes. This report summarizes the background data presented at the task force meeting and the ensuing discussion.

The mammalian target of rapamycin (mTOR) protein complex functions as an integration center for various intracellular signaling pathways involving cell cycle progression, proliferation, and angiogenesis. These pathways are frequently dysregulated in cancer, and therefore mTOR inhibition is a potentially important antitumor target. Commercially available mTOR inhibitors include rapamycin (i.e., sirolimus) and temsirolimus. Other agents under investigation include everolimus and deforolimus. mTOR inhibition has been studied in various solid tumors, including breast, gynecologic, gastrointestinal, prostate, lung, and head and neck cancers. Studies have focused on mTOR inhibition as a monotherapy or in combination with other drugs based on the principle that inhibiting as many targets as possible reduces the emergence of drug resistance. Temsirolimus is currently the only mTOR inhibitor that is specifically labeled for treatment of solid tumors. However, preclinical studies and early-phase trials are rapidly evolving. Additionally, research is further defining the complicated mTOR pathways and how they may be disordered in specific malignancies. To address these issues, NCCN convened a task force to review the underlying physiology of mTOR and related cellular pathways, and to review the current status of research of mTOR inhibition in solid tumors.
