Measure Description: ECOG PS stands for Eastern Cooperative Oncology Group Performance Status, which is a scale used to assess how a patient's disease is progressing and how it affects their daily living abilities. The score is discrete and in the range of 0 to 5, higher score indicates worse patient performance.

Measure Description: The clinical stage at initial diagnosis in breast cancer is typically described using the TNM staging system, which takes into account the size of the primary tumor (T), whether the cancer has spread to nearby lymph nodes (N), and whether it has metastasized (spread to distant organs or tissues) (M). The stage is described as Roman numerals from 0 to IV, with higher numbers indicating a more advanced stage of cancer.

Measure Description: The Hormone Receptor Status of a primary breast tumor is defined using estrogen receptor (ER) and progesterone receptor (PR) status. HR-positive tumors were defined as having either ER-positive and/or PR-positive cells, while HR-negative tumors were defined as having neither ER-positive nor PR-positive cells.

Measure Description: HER-2, also known as human epidermal growth factor receptor 2, is a protein that promotes the growth of cancer cells. The primary tumor was HER-2 positive by immunohistochemistry (IHC), indicating overexpression of the HER-2 protein. The primary tumor was HER-2 negative by immunohistochemistry (IHC), indicating no or low expression of the HER-2 protein.

Measure Description: HER-2 status of a primary breast tumor can also be determined using fluorescence in situ hybridization (FISH), which is another laboratory test that provides information about the HER-2 gene. The primary tumor was HER-2 positive by FISH, indicating amplification of the HER-2 gene. The primary tumor was HER-2 negative by FISH, indicating no amplification of the HER-2 gene.
