#1699 Should the Selective Arterial Secretagogue Injection Test for Insulinoma Localization be Evaluated at 60 Seconds or At 120 Seconds?

Introduction: The selective arterial secretagogue injection (SASI) test is considered indispensable for an accurate insulinoma localization. The optimal timing of post-injection evaluation has not been established yet, as some studies recommend 60 seconds [SASI (60 sec)] while others support 120 seconds [SASI (120 sec)].

#1264 Efficacy and Safety of Sunitinib as Long-term Treatment in Japanese Patients with Advanced Pancreatic Neuroendocrine Tumors.

Introduction: The results from recent clinical trials have suggested the ethnical difference in antitumor activity of sunitinib against advanced pancreatic neuroendocrine tumors (PNET), which seemed to be higher in Japanese than those in Western patients.

#1074 Usefulness of a Combination of a 48-Hour Fasting and a Glucagon Tolerance Test

Introduction: The 72-hour fasting test is the gold standard for the diagnosis of insulinoma. However, the test can become a burden for both patients and medical staff and, shortening the duration of fast has been attempted. There are several reports on the high sensitivity of fasting test but only a few reports on its specificity. An insulinoma can be localized using invasive tests such as endoscopic ultrasonography and selective arterial secretagogue injection test. Therefore, insulinoma detection with high specificity may be needed to avoid unnecessary examinations.

#814 Chromogranin A is a Useful Marker in Japanese Patients with Pancreatic Neuroendocrine Tumors

Introduction: Although Chromogranin A (CgA) is known as a useful marker for pancreatic neuroendocrine tumors (pNET) in the West, the usefulness of CgA in Japanese patients with pNETs is unclear.
