Do endoscopic ultrasound-guided fine needle tissue acquisition biopsy samples allow a reliable proliferation assessment of gastrointestinal stromal tumours?
Endoscopic ultrasound-guided fine-needle tissue acquisition does not reliably reflect gastrointestinal stromal tumours' proliferation and size. Alternative parameters should be validated for a pre-surgical prognostic classification. Considering the emerging potentially prognostic genetic markers in gastrointestinal stromal tumours, the reliability of bioptic genotyping is a promising result.
The % hemolysis increased as the age of the unit increased. There was no significant statistical difference between LR-RC and non-LR-RCs. This data did not confirm our hospitals' concerns regarding increased hemolysis following LR.
