A population-based analysis of breast cancer incidence and survival by subtype in Ontario women.

ABSTRACT:

Background

Breast cancer (bca) is the type of cancer most frequently diagnosed among women in Canada. Breast cancer is categorized into various molecular subtypes by the expression of estrogen receptor (er), progesterone receptor (pgr), and her2 (human epidermal growth factor receptor 2). Currently, Canada has no national cancer registry with epidemiology data by subtype. Thus, we conducted a study to determine incidence, survival, and clinicopathologic characteristics by bca subtype [triple negative breast cancer (tnbc); her2+; and hormone receptor-positive (hr+), her2-] in Canadian women newly diagnosed with bca.

Methods

Female patients diagnosed between 1 April 2012 and 31 March 2016 (fiscal 2012-2015) were identified in the Ontario Cancer Registry, and individual patient
