Somatostatin receptor scintigraphy using the 111In-labelled somatostatin analogue octreotide (Octreoscan) was performed in 9 patients with metastatic renal cell carcinoma. In total 11 scintigraphies were performed. Positive tumor uptakes were observed in 9 patients. The results of the octreotide scans were correlated to diagnostic CT and/or X-ray images. Forty (59%) out of 68 known tumor localizations were visualized with the octreotide scan. A second scan following therapy was performed in two patients. These patients showed progressive disease despite treatment and also exhibited intensified uptakes at octreotide scintigraphy. One false positive lesion was observed in the 40 lesions visualized in scintigraphy.
It was concluded that renal cell carcinoma expresses somatostatin receptors, as could be visualized with Octreoscan scintigraphy. The scintigraphic technique can be used as an instrument for in vivo characterization of the disease. The data could also form a basis for future investigations regarding the possible therapeutic effect of octreotide in the management of renal cell cancer.
