Abstract

We present revised Polish guidelines regarding the management of patients harbouring neuroendocrine neoplasms (NENs) of the small intestine and appendix. The small intestine, especially the ileum, is the most common origin of these neoplasms. Most of them are well differentiated with slow growth. Rarely, they are less differentiated, growing fast with a poor prognosis. Since symptoms can be atypical, the diagnosis is often accidental. Typical symptoms of carcinoid syndrome occur in less than 10% of patients. The most useful laboratory marker is chromogranin A; 5-hydroxyindoleacetic acid is helpful in the monitoring of carcinoid syndrome. Ultrasound, computed tomography, magnetic resonance imaging, colonoscopy, video capsule endoscopy, balloon enteroscopy and somatostatin receptors scintigraphy are used in the visualisation. A histological report is crucial for the proper diagnostics and therapy of NENs, and it has been extensively described. The treatment of choice is surgery, either radical or palliative. Somatostatin analogues are crucial in the pharmacological treatment of the hormonally active and non-active small intestine NENs and NENs of the appendix. Radioisotope therapy is possible in patients with a good expression of somatostatin receptors. Chemotherapy is not effective in general. Everolimus therapy can be applied in patients with generalised NENs of the small intestine in progression and where there has been a failure or an inability to use other treatment options. Finally, we make recommendations regarding the monitoring of patients with NENs of the small intestine and appendix. (Endokrynol Pol 2013; 64 (6): 480–493)
