Question:

Grade, Differentiation--All Sites: Should we take the grade from a TNM staging form over a grade stated in a pathology report when the grade mentioned on the TNM staging form is a higher grade (e.g., Pathology report diagnosis is moderately differentiated adenocarcinoma, Gleason's 3+3=6, but the physician checked "poorly differentiated" on the TNM form)?

Discussion:

Answer:

Code the Grade, Differentiation field to 2 [moderatley differentiated]. Code from the pathology report over the TNM staging form. If you do not have access to the path report, use the grade from the TNM form.
