Table 1: Prognostic score calculations for breast cancer patients at disease presentation.

Prognostic factorPointsImpact on overall prognosis

Age (years)Patients younger than 35 years of age present with more aggressive forms of breast cancer and a worse prognosis
≥350
<351

Tumor sizeThe larger the tumor size, the lower rate of survival
T10
T21
T32

Lymph nodesThe presence of positive lymph nodes highly influences the likelihood of recurrence
Negative0
Positive1

Tumor gradeHigher grade tumors are associated with higher rates of distant metastasis and poorer survival
I0
II1
III2

LVILVI is a poor prognostic factor representing ability of the cancer to spread via hematogenous routes
Unidentified0
Identified1

ERHormone receptor positivity is associated with higher response to endocrine therapy and a longer disease-free survival
Positive0
Negative1

PRHormone receptor positivity is associated with higher response to endocrine therapy and a longer disease-free survival
Positive0
Negative1

HER2HER2 overexpression is associated with increased tumor aggressiveness, increased rates of recurrence, and increased mortality rates
Negative0
Positive1

Prognostic factors are adopted from [34]. ER, estrogen receptor; HER2, human epidermal growth factor receptor 2; LVI, lymphovascular invasion; PR, progesterone receptor.
