E-GEOD-17705 - Endocrine Sensitivity Index Validation Dataset

Released on 13 August 2010, last updated on 27 March 2012
Homo sapiens
Samples (298)
Array (1)
Protocols (6)
Validation dataset of 298 ER-positive patients treated with tamoxifen for 5 years. All patients in this dataset have ER+ breast cancer and were uniformly treated with tamoxifen for 5 years. The objective of the study was to correlate levels of genomic markers to outcomes (relapse free survival) in this cohort of uniformly treated patients. Tissue samples were processed and profiled by two different labs (MD Anderson Cancer Center and Jules Bordet Institute).
