Neuroendocrine tumors of the gastrointestinal tract are relatively rare neoplasms derived from the diffuse endocrine system (DES), and classified as APUDomas. These neoplasms include mainly pancreatic endocrine tumors (islet cells) and carcinoids. Although malignant, these tumors are often slow-growing. Frequently, these neoplasms secrete hormonal peptides and vasoactive amines that can produce...

INTRODUCTION AND OBJECTIVE pancreatic endocrine tumors (PET) are difficult to diagnose. Their accurate localization using imaging techniques is intended to provide a definite cure. The goal of this retrospective study was to review a PET series from a private institution. PATIENTS AND METHODS the medical records of 19 patients with PETs were reviewed, including 4 cases of MEN-1, for a period ...

Recent work suggests that between 50 and 75% of small-cell lung cancer (SCLC) tumours have specific high-affinity binding sites for somatostatin. This study evaluated the potential role of the radiolabelled somatostatin analogue, ["l'In]pentetreotide, in the detection and staging of SCLC in patients prior to and after chemotherapy using scintigraphic imaging techniques. Thirteen patients were s...
