Abstract
Background. The presence of somatostatin receptors on carcinoid tumors mediates imaging of tumor
extent and inhibition of tumor growth and marker secretion. This prospective study
aimed to evaluate radiolabeled somatostatin analog scans in the therapeutic workup
of carcinoids.
Methods. Twenty-one patients with carcinoids underwent 26 scans with iodine octreotide or
indium pentetreotide. The results for tumor and metastases imaging were analyzed and
compared with those of a short inhibition test of marker secretion and with those
of metaiodobenzylguanidine scan.
Results. The sensitivity for obtaining images of the overall 43 tumor sites was 72%. We had
no false-positive results. Unknown tumor sites were discovered in three patients.
The results were slightly better with indium pentetreotide and metastases imaging.
A positive scan did not always preclude responsiveness to the functional effect of
octreotide. Results of somatostatin analog scans were better than those with metaidobenzylguanidine.
The two techniques were complementary- in one patient.
Conclusions. The choice of treatment for patients with carcinoid tumors should benefit from functional
inhibition test with octreotide and from indium pentetreotide and metaidobenzylguanidine
scans.
