Key result
Polymer prodrug therapy theoretically targets tumors to protect normal cells and enable higher, safer doses.
Why the study?
Current cancer chemotherapy agents cause significant toxicity, creating a need for more selective drug targeting strategies such as polymer prodrug therapy.
Polymer prodrugs offer a theoretical advantage in cancer therapy by targeting cytotoxic agents to tumors, potentially reducing toxicity and allowing higher doses.

Requires clinical validation in trials; leaves open translation of polymer prodrug theory to oncology practice.
The administration of current cancer chemotherapy agents is associated with significant toxicity and makes these agents ideal candidates for more selective drug targeting. Polymer prodrug therapy is a strategy that provides a means of targeting cytotoxic agents to specific organs or tumour tissues. The principle structure of a polymer prodrug consists of a water soluble polymeric carrier or backbone, linked to the chemotherapeutic drug of choice. The modification of a specific anticancer drug in this way can theoretically allow specific tumour targeting, thus protecting normal cells and allowing higher doses of the drug to be administered whilst reducing the potential toxicity profile.

Coxon et al. (2000) conducted a review in Cancer. Polymer prodrug therapy was evaluated. Polymer prodrug therapy theoretically allows specific tumour targeting of cytotoxic agents, protecting normal cells and enabling higher doses with reduced toxicity.
