Introduction: The role of EUS-FNA in preoperative diagnosis and grading of pNETs is well-established, but it is unclear how Ki-67 expression on cytological specimens obtained by EUS-FNA reflects the value found on surgical specimens.
Aim(s): To report our experience, to describe the feasibility of measurement of Ki-67 on cytological samples, to evaluate its accuracy if compared with the Ki-67 measurement on surgical specimens.
Materials and methods: Retrospective analysis of all cases of pNETs diagnosed by means of EUS-FNA from August 2003. Cytological Ki-67 expression was compared with definitive surgical Ki-67 results.
