title: Dosing modifications of targeted cancer therapies in patients with special needs: evidence and controversies.
abstract: Targeted therapies have revolutionized the treatment of malignancies over the past decade. These agents are generally regarded to posses fewer systemic side effects than traditional cytotoxic chemotherapies. However, patients manifesting organ dysfunction or drug interactions with concurrent medications may require dosing modifications of their targeted therapies in order to reduce the risk of systemic toxicities or reduction of drug efficacies. Studies have shown that wide variations and controversies exist with regard to dosing modifications of drugs, due to the lack of well conducted studies and consensus. Hence, this review was conducted to review the literature on the dosing modification strategies, for 30 commercially available targeted cancer drugs, and to evaluate the current mainstay recommendations and controversies.
