SOMATOSTATIN RECEPTOR SCINTIGRAPHY OF CARCINOID-TUMORS USING THE [IN-111-DTPA-D-PHE(1)]-OCTREOTIDE

Somatostatin-receptor scintigraphy using the In-111-labelled somatosta tin-analogue octreotide ([In-111-DTPA-D-Phe(1)]-octreotide) was perfor med in 40 patients with carcinoid tumours. In 31/40 patients, this sci ntigraphy proved positive compared with the 33/40 patients whose tumou rs were disclosed on CT scans. In addition, 18 previously unidentified lesions were detected with this scintigraphy. Two of these lesions re presented previously undetectable primary tumours. It is concluded tha t somatostatin receptor scintigraphy using [In-111-DTPA-D-Phe(1)]-octr eotide has a future role in the staging of patients with carcinoid dis ease.
