Multiple endocrine neoplasia type 1 (MEN1) is an inherited autosomal dominant disease presenting with pancreatic neuroendocrine tumors (pNETs), parathyroid tumors, or pituitary tumors. Using the PubMed database, we reviewed the literature on information regarding the proper diagnosis and treatment of MEN1-associated pNET. Many cases of MEN1-associated pNET are functioning pNETs. Gastrinomas and insulinomas tend to occur frequently in the duodenum and pancreas, respectively. In addition to diagnostic imaging, the selective arterial secretagogue injection test (SASI test) is useful for localizing functioning pNET. The standard treatment is surgical resection. However, in the case of a functioning pNET, the tumor should first be accurately located using the SASI test before an appropriate surgical method is selected. In cases of a MEN1-associated non-functioning pNET that exceeds 2 cm in diameter, the incidence of distant metastasis is significantly increased, and surgery is recommended. In cases of unresectable pNET, a somatostatin analog has been shown to demonstrate antitumor effects and is considered to be a promising treatment. In addition, molecular-targeted drugs have recently been found to be effective in phase III clinical trials.

1) Osaka City University Medical School provides basic life support courses in the Skills Simulation Center. Most instructors are members of the Life Support Club, a medical students' extracurricular activity.2) We investigated the numbers and opinions of participants(December 2006 through July 2008). The numbers of trainee and instructors were 1071 and 1223, respectively. The student instructors considered their activities worthwhile.3) The trainees highly appreciated the student instructors and showed that the effectiveness of training was excellent. Our results show that basic life support courses taught by medical students are beneficial for both trainees and student instructors.
