Special Issue Information

Dear Colleagues,

Cancer is the second leading cause of death after cardiovascular diseases in developed countries. Despite rapid medicinal and pharmaceutical chemistry developments, chemotherapy is still a significant challenge. In the last decade, the development of effective targeted drug delivery systems for treating cancer has been a top priority in biomedical technology.

Targeted drug delivery is a system for specifying the drug moiety directly into its targeted body area (organ, cellular, and subcellular level of specific tissue) to overcome the specific toxic effect of conventional drug delivery, thereby reducing the amount of drug required for therapeutic efficacy. This targeted strategy enriches the concentration of the therapeutic agent in cells/tissues; as a result, low doses can be used, particularly if there is a contradiction between the therapeutic activity and the toxic effects of the agent. Increasing the concentration of therapeutic agents in the target location also improves their therapeutic index by enhancing the efficacy and/or increasing the tolerability in biological systems. Thus, targeted drug delivery is a priority approach in modern pharmacology.

This Special Issue intends to provide a forum for original research articles and reviews on the development of targeted drug delivery approaches. We invite researchers to share their ideas and results related to the development of drug delivery platforms and their potential application in treatment and diagnostics.

Despite remarkable recent progress in developing anti-cancer agents, outcomes of patients with solid tumors remain unsatisfactory. In general, anti-cancer drugs are systemically administered through peripheral veins and delivered throughout the body. The major problem with systemic chemotherapy is insufficient uptake of intravenous (IV) drugs by targeted tumor tissue. Although dose escalation and treatment intensification have been attempted in order to increase regional concentrations of anti-tumor drugs, these approaches have produced only marginal benefits in terms of patient outcomes, while often damaging healthy organs. To overcome this problem, local administration of anti-cancer agents can yield markedly higher drug concentrations in tumor tissue with less systemic toxicity. This strategy is most commonly used for liver and brain tumors, as well as pleural or peritoneal malignancies. Although the concept is theoretically reasonable, survival benefits are still limited. This review summarizes clinical results and problems and discusses future directions of regional cancer therapy with local administration of chemotherapeutants. Full article
