Comparative receptor autoradiography in various cancer types (A = HE staining) with I-125-JR11 (B+C) and I-125-Tyr3-octreotide (D+E). B and D are the respective total binding, C and E the respective non-specific binding. Bars = 1 mm.
I: Breast cancer. II: Renal cell cancer. III: Medullary thyroid cancer. IV: Non-Hodgkin lymphoma. V: Colon cancer. In cancers I-V, the sections were incubated with 30’000 cpm/100 μl of antagonist or agonist. Cancers I-IV show a much higher density of sst2 with the antagonist. The colon cancer V is negative. VI: Ileal NET, incubated with 10’000 cpm/100 μl of antagonist or agonist. Credit: Jean Claude Reubi, Institute of Pathology, University of Berne, Berne, Switzerland.
