A hydroxyapatite based bioresorbable material is incorporated with
anti-cancer agents to form an implant used for treatment against cancer.
Sustained release of the anti-cancer agents may be achieved after
implantation at the targeted sites. The dosage of the anti-cancer agent,
the microstructure, morphology, and composition of the bioresorbable
material allow control of the release profile. The invented implant may be
used for drug delivery, chemotherapy, or gene therapy.
