Pancreatic Endocrine Tumors
Pancreatic endocrine tumors (PETs) are uncommon, accounting for 2% of all pancreatic neoplasms. Previously, it had been noted that somewhere between 60% to 85% of PETs were functioning tumors and were associated with a variety of clinical syndromes (Table 8-1). In today’s world, this no longer is true, and PETs often present without clinical syndromes, often identified incidentally by radiologic imaging. Because patients with nonfunctioning PETs are either asymptomatic or present with nonspecific symtpoms, fine needle aspiration (FNA) is often employed as a diagnostic test. It can also be used to establish a diagnosis of metastatic disease.
