Bloom-Richardson grading system—Synonyms: Modified Bloom-Richardson (BR), Scarff-Bloom-Richardson (SBR), SBR Grading, BR Grading, Elston-Ellis modification of Bloom-Richardson grading system. The Bloom-Richardson grading scheme is a semi-quantitative grading method based on three morphologic features of invasive (no-special-type) breast cancers.

This modification provides somewhat more objective criteria for the three component elements of grading and specifically addresses mitosis counting in a more rigorous fashion ( 4 ). The Nottingham system is also called the Bloom–Richardson–Elston system (BRE), or the Elston-Ellis modification of the Scarff-Bloom-Richardson grading system. [15] [16] It grades breast carcinomas by adding up scores for tubule formation , nuclear pleomorphism , and mitotic count , each of which is given 1 to 3 points. It surprising that Elston & Ellis ignore the fact that "10 HPFs" on different microscopes represent different sample areas and that they do not standardize the sampling area. Calculating Nottingham score. Grade I = 3-5 points.

The Elston and Ellis (EE) histologic grading system, originally developed for human breast cancer, is commonly used to grade feline mammary carcinomas, although it is not really adapted for this species, hence the need of a more relevant grading system.
