Molecular prognostic factors in small-intestinal neuroendocrine tumours.

ABSTRACT:

Background

Small-intestinal neuroendocrine tumours (SI-NETs) represent a heterogeneous group of rare tumours. In recent years, basic research in SI-NETs has attempted to unravel the molecular events underlying SI-NET tumorigenesis.

Aim

We aim to provide an overview of the current literature regarding prognostic and predictive molecular factors in patients with SI-NETs.

Method

A PubMed search was conducted on (epi)genetic prognostic factors in SI-NETs from 2000 until 2019.

Results

The search yielded 1522 articles of which 20 reviews and 35 original studies were selected for further evaluation. SI-NETs are mutationally quiet tumours with a different genetic make-up compared to pancreatic NETs. Loss of heterozygosity at chromosome 18 is the most frequent genomic a
