Preliminary evaluation of indigenous 90 Y-labelled microspheres for therapy of hepatocellular carcinoma.

摘要: Background & objectives: Yttrium-90 ( 90 Y)-based radioembolization has been employed to treat hepatocellular carcinoma (HCC) as commercial radioactive glass and polymeric resin microspheres. However, in India other Asian countries, these preparations must be imported are expensive, validating the need for development of indigenous alternatives. This work was aimed develop an economically logistically favourable alternative radioembolizing agents HCC therapy. Methods: The preparation Y-labelled Biorex 70 microspheres optimized vitro stability assessed. Hepatic tumour model generated Sprague-Dawley rats by orthotopic implantation N1S1 rat cell line. In vivo localization retention assessed seven days, impact on growth studied histological examination biochemical assays. Results: Under optimal conditions, >95% Y-labelling yield Biorex70 obtained, showed excellent labelling (>95%) at days. animal studies, were retained (87.72±1.56% liver 7 days). Rats administered with exhibited lower weight ratio, reduced serum alpha-foetoprotein level greater damage tissue compared controls. Interpretation conclusions: stable therapeutic effect tissue, indicating potential further study towards clinical use.
