Treatment-associated adverse event management in the advanced renal cell carcinoma patient treated with targeted...

Targeted therapy for advanced renal cell carcinoma (RCC) has recently expanded the available treatment options for patients with these malignancies. The rapid introduction of novel treatment options into clinical practice within a relatively short time frame has created some new challenges pertaining to adverse event (AE) management in patients with advanced RCC. Accumulating safety data from the pivotal phase III clinical trials of the anti-vascular endothelial growth factor (VEGF) antibody bevacizumab plus interferon, VEGF receptor tyrosine kinase inhibitors (sunitinib, sorafenib, and pazopanib), and mammalian target of rapamycin inhibitors (temsirolimus and everolimus) have served to characterize the toxicity profiles of these novel agents. Overall, it is evident that RCC-directed targeted therapy differs from immunotherapy and cytotoxic chemotherapy in terms of a number of unique nonhematologic AEs (some of which have not been traditionally encountered in oncology practice) and that there are distinctions within and across the various classes of agents with respect to the most prominent AEs and the risk for less common but serious complications. Although treatment-associated AEs are common, the majority of AEs reported during clinical trial experiences were grade 1 or 2 in severity and manageable with intervention in the form of supportive measures and/or dosage modification. Therefore, despite the relatively complex AE profiles of RCC-directed targeted therapy, patient education, consistent monitoring with a focus on early detection by health care providers (oncologists, general physicians, nurses), and the application of emerging AE management strategies may allow for prolonged treatment in most patients with advanced RCC.
