Purpose To estimate the prognostic impact of estrogen receptor (ER)-status among women
with primary invasive breast cancer, according to age at diagnosis. Methods We studied …

Estrogen receptor (ER) status is considered as an important prognostic factor as well as a
predictive factor for endocrine responsiveness in breast cancer. We analyzed the distribution …

Purpose Breast cancer mortality began declining in many Western countries during the late
1980s. We estimated the proportion of improvements in stage-and age-specific breast …

Our aim was to estimate how long‐term mortality following breast cancer diagnosis depends
on age at diagnosis, tumor estrogen receptor (ER) status, and the time already survived. We …

Introduction The association of breast cancer patients' mortality with estrogen receptor (ER)
status (ER+ versus ER-) has been well studied. However, little attention has been paid to the …

Background Previous studies found that the risk of breast cancer–related death is greater in
estrogen receptor (ER)-negative disease than in ER-positive disease within 5 years of …

Background Increasing evidence shows the importance of young age, estrogen receptor
(ER), progesterone receptor (PR) status, and HER-2 expression in patients with breast …

Purpose Since 1990, overall breast cancer mortality rates in the United States decreased
24%. This decline has been attributed to mammography screening and adjuvant systemic …

ER+ and ER-tumors exhibit different histopathological and clinical properties. Receptor
determination exists as a marker with predictive value rather than prognostic importance …

Mortality improvements in young women with breast cancer (BC) may be attributable to
treatment advances; screening likely plays a less significant role as mammography is not …
