Brief Summary
Identifying the malignancy of pancreatic mass using endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is important for treatment decision-making and prognosis prediction. The sensitivity of EUS-FNA cytology specimens based on Papanicolaou (Pap) staining is low, which hampers accurate diagnosis of pancreatic mass. We assessed the diagnostic value of immunohistochemical (IHC) and immunofluorescence (IF) staining for methionyl-tRNA synthetase 1 (MARS1).

Outcome Measures
Primary Outcomes (1)
The comparison of sensitivity between conventional staining method and new staining method
The sensitivity of new staining method will be compared with the conventional Pap staining of endoscopic ultrasound-guided fine-needle aspiration cytology
1 year
Secondary Outcomes (1)
The evaluation of correlation index of staining at three type slides
1 year
Study Arms (1)
Pancreatic Cancer
EXPERIMENTALThis arm includes patients with pancreatic cancer. Cytology specimens will be obtained with endoscopic ultrasound-guided fine-needle aspiration in patients with pancreatic cancer. Cytology staining will be performed in the cytology specimens.
Interventions
Two staining will be performed in cytology specimens obtained from same patient. The cytology specimen will be obtained using endoscopic ultrasound-guided fine needle aspiration. Three types of slides (direct smear, thinprep, surepath) are prepared for staining. 1. conventional cytology staining method 2. new cytology staining method using antibody of methionyl-tRNA synthetase 1
Eligibility Criteria
You may qualify if:
- Patients with pancreatic cancer confirmed by imaging (CT, MRI, PET-CT)
- Patients with pancreatic cancer diagnosed using cytology by endoscopic ultrasound
- Patients who underwent surgical treatment with pancreatic cancer
You may not qualify if:
- Minors under the age of 19, vulnerable subjects such as illiteracy
- Excludes necrotic specimens
- Samples with non-diagnostic cytology results and insufficient cells for further evaluation
- Samples classified as neoplastic (benign or other)
