چکیده
We have previously shown that, monoclonal antibodies (mAbs) labeled with the Auger electron emitter I are more in vitro, 125 cytotoxic if they remain at the cell surface and do not internalize in the cytoplasm. Here, we assessed the biological efficiency in vivo of internalizing and non internalizing I-labeled mAbs for the treatment of small solid tumors. 125

Brief intraperitoneal radioimmunotherapy of small peritoneal carcinomatosis using high activities of noninternalizing I - labeled 125 monoclonal antibodies
We assessed the efficiency and toxicity of brief-intraperitoneal radioimmunotherapy (Bip-RIT) using high activities of I-labeled 125 monoclonal antibodies (mAbs) in the treatment of small volume peritoneal carcinomatosis.

متن کاملComparison between Internalizing Anti-HER2 mAbs and Non-Internalizing Anti-CEA mAbs in Alpha-Radioimmunotherapy of Small Volume Peritoneal Carcinomatosis Using 212Pb
BACKGROUND AND PURPOSE We assessed the contribution of antibody internalization in the efficacy and toxicity of intraperitoneal α-radioimmunotherapy (RIT) of small volume carcinomatosis using (212)Pb-labeled monoclonal antibodies (mAbs) that target HER2 (internalizing) or CEA (non-internalizing) receptors. MATERIALS AND METHODS Athymic nude mice bearing 2-3 mm intraperitoneal tumor xenografts...
متن کاملIntracavitary radioimmunotherapy to treat solid tumors.
Radioimmunotherapy (RIT) potentially is an attractive treatment for radiosensitive early-stage solid tumors and as an adjuvant to cytoreductive surgery. Topical administration of RIT may improve the efficacy because higher local concentrations are achieved. We reviewed the results of locally applied radiolabeled monoclonal antibodies for the treatment of solid tumors. Intracavitary RIT in patie...

UNLABELLED We assessed the efficiency and toxicity of brief intraperitoneal radioimmunotherapy using high activities of (125)I-labeled monoclonal antibody (mAb) in the treatment of small-volume peritoneal carcinomatosis. METHODS Brief intraperitoneal radioimmunotherapy consisted of a 185-MBq (740 MBq/mg) intraperitoneal injection of (125)I-35A7 (an anti-carcinoembryonic antigen mAb) into athy...
