Chromogranin A is a sensitive marker for detection of recurrence in neuroendocrine tumors
#112
Introduction: The chromogranin family is a family of large acidic proteins which are expressed in neuroendocrine cells. There are several members in this family (Chromogranin A, B (CgA and CgB) and the secretogranins). Here, we show that CgA is an excellent marker to detect recurrence in neuroendocrine tumors.
Aim(s): The aim of this study was to identify which method is the most sensitive to detect recurrence in carcinoid tumors.
Materials and methods: A total of 56 patients with radically operated small intestinal carcinoid tumors were examined using biomarkers (U-5HIAA and CgA) and radiology (CT, US, Octreoscan and 5-HTP-PET) techniques. Patients were monitored every 3-6 months.
