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.

The widely used prognostic markers in cancers include stage, size, grade, node and metastasis. In addition to these common markers, there are prognostic markers specific to different cancer types. For example estrogen level, progesterone and HER2 are markers specific to breast cancer patients.
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).
MammaPrint has been prospectively, clinically validated for use in early stage (I and II) breast cancer patients regardless of estrogen receptor (ER) or Human Epidermal Growth Factor Receptor 2 (HER2) status, with a tumor size ≤ 5.0 cm, and 0-3 positive lymph nodes (LN0-1), with no special specifications for N1mi pathology.
A review of 10,485 individuals all of whom had early stage N1 (<2 cm. in size) or N2 (2 to <5 cm. in size) IPC tumors that had not metastasized to lymph nodes or distant tissues reported that lumpectomy plus adjuvant radiation therapy produced significantly better mean survival times (16.8 years) than lumpectomy (14.2 years) or mastectomy (14.9 ...
G (1–4): the grade of the cancer cells (i.e. they are "low grade" if they appear similar to normal cells, and "high grade" if they appear poorly differentiated) S (0–3): elevation of serum tumor markers; R (0–2): the completeness of the operation (resection-boundaries free of cancer cells or not) Pn (0–1): invasion into adjunct nerves
