 ・Principle investigator: Akiyo Tanabe

 ・Organization:

         Department of Diabetes, Endocrinology and Metabolism, National Center for Global

Aim

1) To build a registry system and a cohort for patients with adrenal tumors

2) To produce new evidences of management of adrenal tumors contributing to clinical

     guidelines
