Utility and clinical significance of endoscopic ultrasound-guided tissue acquisition for diagnosing lymphadenopathies in biliary tract cancer.

ABSTRACT: Lymph node sampling with endoscopic ultrasound fine needle aspiration (EUS-FNA) may affect treatment options for biliary tract cancers. Our aim is to clarify its utility and clinical significance and the factors associated with FNA cytology positivity. Seventy-one consecutive patients with biliary tract cancer who underwent EUS-FNA to diagnose lymphadenopathies from April 2012 to July 2021 were enrolled retrospectively. Lymph nodes with a short diameter over 10 mm and/or fluorodeoxyglucose uptake were considered FNA targets. Samples eligible for cytology were attained in 70 patients with no complications. The FNA cytology-positive rate was 54%. In 35 patients with difficulty in obtaining pathological proof from primary tumors, obtaining a pathological diagnosis was successful in 24 patient
