Use of polymer-drug conjugates for cancer therapy

摘要

CHEMOTHERAPY is usually the first choice for the treatment of many cancer types.According to the American Cancer Society,more than 100 drugs are currently used for chemotherapy,alone or in combination with other drugs or treatments.Many more have been developed as anticancer drug candidates,but only a few of them are expected to come into clinical practice.These drugs vary widely in their chemical composition,how they are taken,their usefulness in treating specific forms of cancer,and their side effects.
