How do you determine if a carcinoid tumor is typical or atypical?
Eugene Woltering, MD, FACS, answers: " Well, the procedure that I use is to:
1. Look at the path report and look for key words like mitotic indices necrosis and the key word differentiation.
2. Get a Ki -67 and clearly, the lower this number the better. Numbers over 20% ( some say 10%) are atypical indicators.
3. Get stain on the tumor for CGA and synaptophysin and ask the path guy/gal to actually count the percentage of cells that are positive/negative."
