Study Endpoints

Primary Endpoints

Response rate
6 months

* Response and progression will be evaluated in this study using the new international criteria proposed by the revised Response Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1) \[Eur J Ca 45:228-247, 2009\]. * In each RECIST response category Oncotype DX scores will be summarized with mean, standard deviation, minimum, 1st, 2nd (median) and 3rd quartiles, and maximum values. OncotypeDx scores range from 0 to 100, with scores \<18 indicating low risk.

Treatment Arms

ArmTypeDescription
Endocrine therapy aloneEXPERIMENTAL* Neoadjuvant endocrine therapy will be given at the discretion of the treating physician as directed by the package insert and could include the following: goserelin, anastrozole, letrozole, exemestane, fulvestrant, or tamoxifen * Frequency of office visits will be decided by the treating physician but must occur no less frequently than every 3 to 6 months for tumor assessment * After 6 months and after 12 months, patients will be assessed; patients who progress will have standard care recommended , and at any point a patient can opt to receive standard care even if she has not progressed on neoadjuvant endocrine therapy * Information on quality of life will be collected at baseline, Year 1, and Year 2 by the FACT-B questionnaire * Archival tissue will be collected and sent to Genomic Health for analysis using the Oncotype DX assay. The Recurrence Score predicts chemotherapy benefit and indicates the 10-year risk of recurrence (will not be used to determine treatment)
