UNLABELLED: The treatment of advanced lung cancer remains a major challenge in clinical medicine, justifying an urgent need for new therapeutic approaches. In a rather unique international collaboration, 43 patients with advanced lung cancer were treated using iodine-131-labeled tumor necrosis therapy chimeric antibody (131I-chTNT). METHODS: Patients were treated either with intravenous (i.v.) infusion (n = 22), intratumoral injection using a computer tomography (CT)-guided catheter (n = 16), or combination i.v. and intratumoral infusion (n = 5). All patients, regardless of route of administration, received 2 doses of 131I-chTNT on days 1 and 14. RESULTS: The results showed that of those patients receiving i.v. injection alone, 2 achieved partial response (PR) (9%), 16 had stable disease (73%), and 4 progressed (18%). Of those patients receiving intratumoral injection only, 1 had a complete response (CR) (6%), 8 achieved PR (50%), 7 had stable disease (44%), and none (0%) progressed. Finally, of those patients receiving both i.v. and intratumoral administration, 1 had a CR (20%), 1 achieved PR (20%), 2 had stable disease (40%), and 1 (20%) showed progression. CONCLUSIONS: These promising results demonstrate that sufficient doses of radiolabeled antibody can be safely delivered to tumors to cause significant therapeutic effects in advanced lung cancer.
