Problems solved by technology

Nonetheless, despite more than a decade of development of multiple residual risk signatures, passing these tests has not significantly accelerated the development of stratified or targeted medicine
None of the Existing Tests Identify Actionable Targets That Could Form the Basis of a Next-Generation Stratified Medicine Approach

[0101] Materials and methods

[0102] The TEAM trial is a multinational, open-label Phase III trial in which patients with hormone receptor-positive 19 Postmenopausal women with early breast cancer were randomly assigned to receive exemestane (25 mg) or tamoxifen (20 mg) once daily for the first 2.5 to 3 years; exemestane (25 mg) thereafter (total 5 years of treatment) (see Figure 11A ). Hormone-receptor (ER and PgR) and HER2 status assessed locally by immunohistochemistry to enter the trial, followed by central confirmation 28 , and confirmed HER2 status by immunohistochemistry and fluorescence in situ hybridization (FISH) 29 . According to ASCO / CAP guidelines 30-32 , to perform all evaluation work. None of the patients received anti-HER2 therapy. Distant recurrence-free survival (DRFS) was defined as the time from randomization to distant recurrence or death due to breast cancer 19 .

[0103] The TEAM trial included a pathology study consisting of 4,736 patients fr...

Abstract

There is described herein a method of prognosing endocrine-only treatment in a subject with breast cancer, the method comprising: a) providing a tumor sample of the breast cancer; b) determining the expression level of at least 40 of the genes listed in Table 4 in the tumor sample; c) comparing said expression levels to a reference expression level of the group of genes from control samples from acohort of subjects; and d) determining the residual risk associated with the breast cancer; wherein a statistically significant difference or similarity in the expression of the group of genes compared to the reference expression level corresponds to a residual risk associated with breast cancer.

Description

[0001] Citations to related applications [0002] The present application claims the benefit of priority to U.S. Provisional Patent Application No. 62 / 263,805, filed December 7, 2015, which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure generally relates to prognosing or classifying breast cancer subjects. More specifically, the present disclosure relates to methods and devices related to the use of biomarkers for the prognosis or classification of breast cancer subjects following endocrine therapy. Background technique [0004] Despite significant improvements in the treatment of early estrogen receptor positive (ER+) breast cancer, clinical problems remain. Mortality reduction with targeted antiendocrine therapy compared to previous 30-40 years 1,2 , but ER+ disease, which accounts for 80% of breast cancers, still accounts for the majority of deaths from early breast cancer 3 . Increasing use of multiparametric gene...
