Colorectal neuroendocrine neoplasms — management guidelines (recommended by the Polish Network of Neuroendocrine Tumours) Nowotwory neuroendokrynne jelita grubego — zasady postępowania (rekomendowane przez Polską Sieć Guzów Neuroendokrynnych)

We present revised diagnostic and therapeutic guidelines for the management of pancreatic neuroendocrine neoplasms (PNENs) proposed by the Polish Network of Neuroendocrine Tumours. These guidelines refer to biochemical (determination of specific and nonspecific neuroendocrine markers) and imaging diagnostics (EUS, CT, MR, and radioisotope examination with a 68 Ga or 99 Tc labelled somatostatin analogue). A histopathological diagnostic, which determines the further management of patients with PNENs, must be necessarily confirmed by immunohistochemical tests. PNENs therapy requires collaboration between a multidisciplinary team of specialists experienced in the management of these neoplasms. Surgery is the basic form of treatment. Medical therapy requires a multidirectional procedure, and therefore the rules of biotherapy, peptide receptor radionuclide therapy, chemotherapy and molecular targeted therapy are discussed.
