WSPÓŁCZESNA DIAGNOSTYKA NOWOTWORÓW NEUROENDOKRYNNYCH Current diagnostics of neuroendocrine tumors

: Neuroendocrine tumors (NEN) are rarely diagnosed neoplasms, which frequency is estimated on about 35 cases/100 000. During last 30 years the number of NEN's new diagnosis increased five-times and nowadays reaches 5,86/100 000/year. It is partially associated with increasing detectability of these tumors. Such diagnostic methods as capsule endoscopy and positron emission tomography are becoming increasingly widely accessible. Though, one should bear in mind that in case of patients diagnosed with NEN cooperation between specialists in different fields of medicine, such as endocrinology, nuclear medicine, oncology, radiology, internal medicine and surgery is needed.
