My father chromogranin is 3300,
After the surgery of pancreatic tumor
It's been nearly 6 months
And in the regular checkups, everytime his C.t scan result is good. What must be reason for the high cga at the moment?

I'm not familiar with this marker. Do you know how it compares to the CA19-9?

Welcome, @casualsuman. Chromogranin A (CgA) is a reliable serum diagnostic biomarker for pancreatic neuroendocrine tumors. @thebobk, if your pancreatic tumor is not a neuroendocrine type of pancreatic tumor, I'm not surprised that you haven't heard of CgA.

Casualsuman, to connect you with others talking about pancreatic neuroendocrine tumors and CgA, I moved your question to this existing discussion in the Neuroendocrine Tumors group:
- High or Fluctuating Chromogranin A Level: What does it mean? https://connect.mayoclinic.org/discussion/chromogranin-a-level-was-539/

I did this so you can read the helpful posts members have made that may help answer your questions and so you can easily connect with members like @kaforester3 @microbe1943 @fightinghopefully @tomewilson @hopeful33250 and others.

While we wait for others to chime in, what has your father's team suggested as next steps for further investigation?
