N2 - Background: Endoscopic ultrasonography (EUS) is commonly used in the evaluation of pancreas masses, and when a liver lesion is visualized, it can undergo a fine-needle aspiration (FNA). This can provide diagnostic and staging information. The purpose of the study was to correlate the findings of patients who underwent EUS FNA biopsy of a pancreas lesion and a liver lesion during the same procedure. Materials and methods: The pathology database at Washington University Medical Center was searched for EUS FNA biopsy cases where biopsy of both the pancreas and liver were performed over a consecutive 10-year period (2003-2013). All pathology reports were reviewed, and clinical information and diagnostic results were recorded. Results: A total of 102 cases were identified. For pancreas cases, 79.4% were malignant and for liver cases, 58.8% were malignant. In pancreas lesions categorized as suspicious for malignancy (9%), the liver biopsy provided a diagnosis of malignancy in 67% of cases. A malignant pancreatic cohort demonstrated a 62.9% liver malignancy. A malignant liver cohort corresponded to a malignant pancreas diagnosis in 86.6% of cases and a suspicious-malignant group of 98.3%. Conclusions: The 102 cases with concomitant EUS FNA biopsy of the pancreas and liver demonstrated the ability to provide a diagnosis of pancreas malignancy and correlate regional metastatic malignancy in the liver. In patients with a pancreas mass and in the appropriate clinical setting, a liver EUS FNA biopsy has the ability to provide a diagnosis of malignancy and demonstrate a high positive predictive value of malignancy in the pancreas (98.3%).
