Abstracts

EN

Neuroendocrine tumours (NET) are a rare and heterogeneous group of neoplasms. The majority of patients are diagnosed with locally advanced or metastatic disease, and curative surgery is rarely an option. Treatment approaches involving targeted therapy, including the use of agents inhibiting the mTOR signalling pathways involved in neuroendocrine tumourigenesis, provide new therapeutic options for patients with NETs.
