Current diagnosis and treatment of gastrointestinal carcinoids in a series of 101 patients: the significance of serum chromogranin-A, somatostatin receptor scintigraphy and somatostatin analogues.

Abstract

a) Tumor size (especially in appendiceal and gastric carcinoids) and, also, the dispersion of disease, highly predict the evolution of the patients; b) serum Chromogranin-A seems to be a very useful tumor marker for the diagnosis and follow-up of pts with GI carcinoids; c) the introduction of new imaging techniques and especially OCTREOSCAN contributes to a better localization of the primary tumors and their metastases, as well as, to the right decision of the appropriate medical treatment; d) surgical excision is the treatment of choice in nonmetastatic tumors; and e) in pts with metastatic disease, the administration of Somatostatin analogues improves their quality of life.
