The coming of age of cancer radioimmunoconjugates.

Great progress in imaging and therapy with radioimmunoconjugates was discussed at the fourth conference on radioimmunodetection and radioimmunotherapy of cancer. Monoclonal antibody-based cancer imaging agents are awaiting marketing approval and newer, potentially improved forms are in development. Tumor responses to radioimmunoconjugates are also being reported in increasing numbers, this is especially so with radiosensitive tumors and in regional or direct applications.
