Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Endoscopic ultrasound (EUS) with fine needle aspiration (FNA) for cytology and/or fine needle biopsy (FNB) for histology may be used in the diagnostic work-up of intrathoracic and intrabdominal lesion of unknown origin. Certain lesions (such as pancreatic adenocarcinoma) are often well characterized by cytology assessment of FNA-samples while others are not (such as GIST-tumors).

This study is a part observational (early study phase) and part interventional study (late study phase) on the diagnostic accuracy of EUS-assisted tissue sampling by FNA or FNB during a 10-year period on a tertiary endoscopy centre.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Variables affecting the diagnostic accuracy of EUS-FNA and EUS-FNB in different cases and tumor scenarios will be studied in detail such as the influence of medical equipment used (i.e the different types and sizes of puncture needles), the experience of the endosonographers, cytopathologists and pathologists and the use of rapid on-site evaluation of cytology samples.

Each study case is reviewed post-EUS (according to the schedule precised below) regarding further diagnostic work-up, neoadjuvant treatment, surgery result, clinical follow-up, (neo)adjuvant treatment, and survival. Non-parametrical tests will be applied as the main statistical method.
