Endoscopic Ultrasound-Guided Fine-Needle Aspiration of Suspected Locoregional Rectal Cancer Localizations: A Valuable Tool.

ABSTRACT:

Introduction

Organ-preserving treatment for rectal cancer using local excision (LE) and/or chemoradiotherapy (CRT) is increasingly used. Locoregional metastasis precludes LE and locoregional regrowth, recurrence, or persistence after LE or chemoradiation (CRT) may prompt total mesorectal excision (TME). We believe that the time has passed to make such life-changing treatment decisions without pathological confirmation and investigated the use of linear endoscopic ultrasound with fine-needle aspiration (EUS-FNA).

Case presentations

We report 8 cases of suspected locoregional tumor growth (LRTG) on MRI: adjacent or in the rectal wall, within the mesorectal fascia, high presacral region, and obturator foramen. MRI images were studied thoroughly before and during EUS to identify
