Summary
The goal of this study is to compare several methods for measurement of Chromogranin A in
their ability to serve as a marker for disease activity in patients with neuroendocrine
tumors.
Further, in a subgroup, we will determine if taking a proton pump inhibitor affects
Chromogranin A levels.
