| [ Summary ] |
To facilitate the detection of early‒stage pancreatic cancer with a tumor diameter of 10 mm or less (which can be expected to have good long‒term outcomes), it is essential to screen patients for indicators of tumors (e.g., pancreatic‒duct dilatation, pancreatic cysts, bile duct dilation) during multiphasic health screening and routine medical check‒ups and to identify patients who should undergo endoscopic ultrasonography (EUS), which can provide a more accurate diagnosis of pancreatic cancer than other diagnostic modalities. EUS‒fine‒needle aspiration (EUS‒FNA) can provide a very accurate pathological diagnosis. Recently, however, cases of tumor seeding following EUS‒FNA have been reported. Thus, the indications for EUS‒FNA remain controversial. The development of techniques that can achieve the diagnostic accuracy of EUS‒FNA should be emphasized. |
