title: Radioimmunotherapy of transplanted small cell lung cancer with 131I-labelled monoclonal antibody.
abstract: Monoclonal antibody TFS-4 has previously been shown to react selectively with human small cell lung cancer (SCLC). We evaluated the use of 131I-labelled TFS-4 for the treatment of established human SCLC transplanted in nude mice. The specific accumulation of the antibody in the transplanted tumour was recorded by both scintigraphic and biodistribution studies. Administration of 200 microCi 131I-labelled TFS-4 inhibited tumour growth when compared with the same radiation dose of the control monoclonal antibody. The therapeutic effect was dose-dependent and complete disappearance of the tumour was observed transiently in one out of the three animals following the administration of 500 microCi 131I-labelled TFS-4.
