Abstract
The present invention relates to: biodegradable microbeads with improved anticancer drug adsorptivity, containing albumin and dextran sulfate; a preparation method therefor; and a method for treating cancer using the same. The microbeads of the present invention is prepared from a biocompatible and biodegradable polymer so as to be safe to the human body, and can effectively inhibit the growth of a tumor by effectively blocking a blood vessel which supplies nutrition to a liver tumor and continuously releasing an anticancer drug adsorbed on surfaces of the beads. Therefore, the present invention can be useful for liver cancer chemoembolization.
