The Nottingham prognostic index (NPI) is used to determine prognosis following surgery for breast cancer. [1] [2] Its value is calculated using three pathological criteria: the size of the tumour; the number of involved lymph nodes; and the grade of the tumour. [1] It is calculated to select patients for adjuvant treatment.
Breast cancer classification divides breast cancer into categories according to different schemes criteria and serving a different purpose. The major categories are the histopathological type, the grade of the tumor, the stage of the tumor, and the expression of proteins and genes.
With a 5-year survival rate of 81% to 94%, mucinous breast cancer tends to have a good prognosis. There is also a low incidence of metastasis to lymph nodes. [2] Pure mucinous carcinoma has a more favorable prognosis compared to mixed type mucinous carcinoma.
The American Cancer Society reports 5-year relative survival rates of over 70% for women with stage 0-III breast cancer with a 5-year relative survival rate close to 100% for women with stage 0 or stage I breast cancer. The 5-year relative survival rate drops to 22% for women with stage IV breast cancer. [3]
The factors included here tend to be generalizable to most breast cancers, and further information can be found in the main articles on breast cancer and breast cancer screening. The prognosis of ductal carcinomas in general depend, in part, on its histological subtype. Mucinous, papillary, cribriform, and tubular carcinomas have longer ...
In the USA the five-year survival rate for localized breast cancer was 96.8%, while in cases of metastases it was only 20.6%. Because the prognosis for breast cancer was at this stage relatively favorable, compared to the prognosis for other cancers, breast cancer as cause of death among women was 13.9% of all cancer deaths.
Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
3D medical illustration depicting the TNM stages in breast cancer. Cancer staging can be divided into a clinical stage and a pathologic stage. In the TNM (Tumor, Node, Metastasis) system, clinical stage and pathologic stage are denoted by a small "c" or "p" before the stage (e.g., cT3N1M0 or pT2N0).
