Clinical Trial Summary

It is a prospective randomized controlled study to evaluate the diagnostic accuracy of SurePath™ liquid-based cytology in endoscopic ulatrasound-guided sampling.

Description:

The SurePath™ has been approved by the FDA since 1997. Investigators want to compare the diagnostic accuracy of SurePath™ liquid based cytology and conventional smear cytology(CSC) in EUS-FNA sampling of esophageal, gastric, duodenal subepithelial tumors, periesophageal and perigastric lymph nodes.

The investigators randomly assigned (1:1) patients to the SurePath™ group or the CSC group. Aspirates from the first needle pass were processed by one method, aspirates from the second pass by the other method, and specimens from the last pass were processed as core biopsy samples. The primary endpoint was the diagnostic efficacy of each method, with the final diagnosis as the gold standard. The aim of this study is to confirm that the SurePath™ is not inferior than the conventional smear test.

Exclusion Criteria:

• Those who did not agree with the study

Related Conditions & MeSH terms

• Digestive System Neoplasms
• Gastrointestinal Neoplasms
• Submucosal Tumor of Gastrointestinal Tract

Intervention

Diagnostic Test:
• SurePath™
In the liquid-based cytology, a fine-needle aspirated sample is immediately inserted into a container containing a commercially available preservative solution without a separate slide-smearing procedure and immediately after the fine-needle aspiration.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Diagnostic accuracy	Pathologic results of the surgical specimen or core needle biopsy will be checked whether it is malignancy or benign. If benign diagnosis is made by combining the results of SurePathTM and conventional smear test, the follow-up period is 6 months and the results of the 6-month follow-up imaging and additional biopsy are checked. The combined results make a final diagnosis and are compared between two groups.	6 months after randomization
Secondary	Cytomorphologic feature	We will evaluat the cytomorphologic features of each method. We plan to investigate whether there are differences in the level of artifacts, the degree of background cleanliness, and tumor cell characteristics such as cellularity.	6 months after randomization
