Introduction: Numerous studies have suggested that CgA determination may be useful for the diagnosis and follow-up of neuroendocrine tumors (NETs).
Aim(s): To determine the sensitivity of CgA in diagnosis of non-functioning NETs, and the correlation of CgA change with radiographic response in patients with advanced non-functioning NETs.
Materials and methods: Serial CgA determinations were performed in 29 patients (24 pNETs, five others, 80 visits) with locally advanced (n=3) or metastatic (n=26) non-functioning NETs on various treatments. Changes in CgA levels over 25% were considered as significant. CT and/or MRI were performed at each visit for response determination using RECIST 1.1 criteria.
