↵* Tumor and tumor-invaded duodenum in patient 2 showed, by histology, predominant fibrosis and only sparse diffusely distributed tumor cells with moderate expression of NT receptor.
Activity in tissues is expressed in %ID/g·10−4, corrected for physical half-life of isotope. Numbers in parentheses represent tumor-to-normal tissue radioactivity ratios.
