Pancreatobiliary cytology in the multidisciplinary setting

Area of Science:

• Gastroenterology
• Cytopathology
• Surgical Oncology

Background:

• Pancreatic tumors often present late, limiting surgical options.
• Endoscopic ultrasound-guided fine needle aspiration (EUS FNA) is a key diagnostic tool.
• Multidisciplinary team (MDT) meetings are essential for patient management.

Purpose of the Study:

• To review the role of EUS FNA cytology in managing patients with pancreatic tumors.
• To highlight the importance of differential diagnosis in pancreatic lesions.
• To discuss strategies for improving diagnostic accuracy and patient care.

Main Methods:

• Review of clinical management strategies involving EUS FNA cytology.
• Analysis of diagnostic categories for pancreatic lesions.
• Evaluation of rapid on-site evaluation (ROSE) by biomedical scientists.

Main Results:

• EUS FNA cytology is often the primary diagnostic method for pancreatic adenocarcinoma.
• A significant proportion of lesions discussed in MDTs are not primary adenocarcinoma, requiring broad differential diagnoses.
• Categorizing cytology results (malignant, suspicious, atypical, benign, inadequate) aids decision-making.
• Rapid on-site evaluation (ROSE) by trained biomedical scientists can prevent inadequate cytology results.

Conclusions:

• EUS FNA cytology plays a vital role in the multidisciplinary management of pancreatic tumors.
• Accurate and timely diagnosis, including identification of resectable tumors, is critical.
• Innovative approaches like ROSE by biomedical scientists enhance diagnostic efficiency and patient care.
