摘要

The vast majority of neuroendocrine 'neoplasms (NENs) are sporadic, although recent evidence has indicated that a subset of these cancers may also originate as a result of genetic germline mutations. To date, 10% of these cancers can be linked to an inherited genetic syndrome. Genetic diagnosis is crucial for patients with a suspected hereditary NEN syndrome, as it recognizes patients carrying germline mutations and allows for personalized clinical follow-up, considering the higher risk of developing other tumours. The potential for early genetic detection has significant implications for the treatment of patients with hereditary NEN syndrome, as it may facilitate the delivery of precision therapy that differs from that typically provided to other patients. Thus, the integration of genotypic and phenotypic diagnostic methods help clinicians to provide more informed treatment and to extend appropriate prevention to family members.
