Fig 1.
Preparation of EUS-FNA specimens.
The EUS-FNA samples were placed in CytoRich Red and separated into solid and liquid materials. The solid materials were fixed in 10% buffered neutral formalin for CB preparation. The liquid materials (LBC) were treated to create cytological specimens. The residual LBC specimens were stored at 4°C until DNA extraction. EUS-FNA, endoscopic ultrasound-guided fine needle aspiration; CB, cell block.
