Description
This data set contains the expression of 1753 genes in 47 surgical specimens of
human breast tumours from 17 different individuals before and after chemotherapy treatment.encoding

The Human Breast Tumors dataset is a companion resource for the paper of
Perou et al. (2000), and was downloaded from the Stanford Genomics Breast
Cancer Consortium Portal

This data consists of 47 breast cancer samples and 1753 cDNA clones
pre-selected by P�rez-Enciso et al. (2003) to draw their Fig. 1.
The authors selected 47 samples for which there was information
at least before or before and after chemotherapy treatment.
There were 20 tumours that were microarrayed both before
and after treatment.References
