Nottingham Breast Cancer Grade

Calculate Nottingham histological grade (Grade 1-3) from three components scored 1-3 each: tubule formation, nuclear pleomorphism, and mitotic count per HPF. Total 3-5 = Grade 1; 6-7 = Grade 2; 8-9 = Grade 3.

Formula

Result = f(patient inputs, clinical reference)

patient inputs
Age, weight, height, lab values, vitals, or clinical findings entered into the Nottingham Grade.
clinical reference
Reference range, scoring system, or population standard the result is compared against.
Result
Computed clinical score, risk estimate, or diagnostic value.

Clinical results are decision-support only and must be interpreted by a qualified clinician.

Glossary and Definitions

Clinical score
A numeric value derived from patient inputs that estimates risk, severity, or diagnostic likelihood for a given condition.
Reference range
The set of values considered normal for a healthy population, used to interpret a calculated result.
Sensitivity
The probability that a positive result correctly identifies a patient with the condition.
Specificity
The probability that a negative result correctly identifies a patient without the condition.
