Site-Specific Factor 7

Nottingham or Bloom-Richardson (BR) Score/Grade


**Note 1:** TNM recommends the Nottingham combined histologic grade (Elston-Ellis modification of the Scarff-Bloom-Richardson grading system). Terms seen on pathology reports may include * Bloom-Richardson (BR) * Modified Bloom-Richardson, BR * BR grading * Scarff-Bloom-Richardson * SBR grading * Elston-Ellis modification of Bloom-Richardson score * Nottingham modification of Bloom-Richardson score * Nottingham modification of Scarff-Bloom-Richardson * Nottingham-Tenovus grade * Nottingham grade **Note 2:** Code the highest score prior to neoadjuvant treatment. **Note 3:** Code the tumor grade using the following priority order * BR scores 3-9 * BR grade (low, intermediate, high). **Note 4:** BR score may be expressed as a range, 3-9. The score is based on three morphologic features of "invasive no-special-type" breast cancers * Degree of tubule formation/histologic grade * Mitotic activity * Nuclear pleomorphism/nuclear grade of tumor cells). If a report describes any of the factors with words (low, intermediate, high) rather than numbers, do not attempt to translate these words into a score or number; use codes 110-130. **Note 5:** If only a grade of 1 through 4 is given with no information on the score and it is unclear if it is a Nottingham or BR Grade, code 999. **Note 6:** Code the highest score prior to neoadjuvant treatment if multiple scores are reported. * For examples, different scores may be reported on multiple pathology reports for the same primary cancer; different scores may be reported for multiple tumors assigned to the same primary cancer
