8 patients with papillary cancer (4 with metastases, 4 in remission),
7 follicular cancer patients (6 with metastases), 2 patients with anap
lastic thyroid cancer, and 4 other non-medullary thyroid cancer patien
ts all received an intravenous bolus injection of 220 MBq [In-111-DTPA
-D-Phe(1)]octreotide. Planar anterior and posterior gamma camera image
s of head-neck, chest and abdomen were obtained 24 and 48 h after inje
ction. All primary cancers showed [In-111-DTPA-D-Phe(1)]octreotide upt
ake; none occurred in patients in remission. The results were compared
with conventional radio-iodine scintigraphy in patients with metastas
ised, differentiated thyroid cancer.
