What is the significance of EUS in pancreatic cancer?

EUS most accurate but costly, but equally dx as CT (if not CT more after advances in it seeing vascularization and resectability) Most sensitive method is EUS, and give ability to make FNA/FNB which is safe, reliable w/ no false-positive results (97% specificity). EUS guided FNA proves malignancy and rules out other diseases (sarcoidosis/TB) and distinguish adenocarcinoma from other tumors (neuroendcrine/ lymphomas) But usually we don't need biopsy for resection.
