Question:

Grade, Differentiation--Breast: Is "histological grade" another way of saying "tubule formation" which would result in the following case having a Bloom-Richardson (BR) score of 7 which would be coded to grade 2? See discussion.

Discussion:

Final path diagnosis stated: Invasive ductal ca, histological grade 3/3, nuclear grade 2/3, mitotic index-moderate.

Answer:

Yes. Code the Grade, Differentiation field to 2 [Grade 2] for this case. This case has a BR score of 7 which converts to a grade of 2. This pathologist seems to be describing the three parts of the BR system: tubule formation, mitotic activity and nuclear grade.
