What is a positive Allred score?
The Allred score combines the percentage of positive cells and the intensity of the reaction product in most of the carcinoma. The 2 scores are added together for a final score with 8 possible values. Scores of 0 and 2 are considered negative. Scores of 3-8 are considered positive.
Is a high Allred score good?
An Allred score of ≥3 is a good cut-off to predict benefit from tamoxifen, but only when using identical standardized staining methods and primary antibody.
Is ER PR positive a good thing?
Tumors that are ER/PR-positive are much more likely to respond to hormone therapy than tumors that are ER/PR-negative. You may have hormone therapy after surgery, chemotherapy, and radiation are finished. These treatments can help prevent a return of the disease by blocking the effects of estrogen.
What is H score in breast cancer?
The H-score is given as the sum of the percentage of staining multiplied by an ordinal value corresponding to the intensity level (0 = none, 1 = weak, 2 = moderate, 3 = strong). With 4 intensity levels, the resulting score ranged from 0 (no staining in the tumor) to 300 (diffuse intense staining of the tumor).
What does H score mean?
The H-score is a method of assessing the extent of nuclear immunoreactivity, applicable to steroid receptors. The score is obtained by the formula: 3 x percentage of strongly staining nuclei + 2 x percentage of moderately staining nuclei + percentage of weakly staining nuclei, giving a range of 0 to 300.
Is chemo necessary for HER2-positive?
Because HER2-positive cancer is considered more aggressive than HER2-negative breast cancer, it is usually treated with chemotherapy after surgery to reduce recurrence risk.
Is it better to have HER2-positive or negative?
Breast cancer cells with higher than normal levels of HER2 are called HER2-positive. These cancers tend to grow and spread faster than breast cancers that are HER2-negative, but are much more likely to respond to treatment with drugs that target the HER2 protein.
