Through the development of somatostatin scintigraphy with the labeled somatostatin analog Indium111-Octreotide, it has recently become possible to accurately diagnose primary tumors of the APUD system as well as their metastases, since these tumors usually have somatostatin receptors. Experience with this method is already available for endocrine and exocrine tumors of the gastrointestinal tract, neuroendocrine and breast tumors, small cell bronchial carcinomas and certain lymphomas. In the present study, this new diagnostic technique was used for the first time in various head and neck tumors (carcinoid of the larynx, Merkel cell tumor, glomus tumor of the carotid and glomus jugulare tumor). Concurrently, some of these tumors shown by this diagnostic method to be somatostatin receptor positive were treated using the somatostatin analog Octreotide, a therapeutic approach new for the ENT-specialty. Our initial results prove that the detection of the ENT tumors which we studied by means of receptor scintigraphy is reliable. The preliminary results of this Octreotide therapy show a growth inhibitory effect, especially for those tumors of the head and neck which are inoperable or are difficult to approach surgically.
