Friday, December 20, 2002But scientists said the genetic signature — the activity of a collection of 70 genes — appears to predict cancer mortality better than traditional measures like tumor size or stage or whether the cancer has spread to a woman's underarm lymph nodes. In the study, 5.5 percent of women whose cancers had a good genetic signature died within the next decade, as against 45 percent of those with bad genetic signatures. That’s pretty impressive, and much better than any of our other methods of predicting the potential for a breast tumor to spread. The main page of the New England Journal of Medicine’s website has a photo of the the microarray used to profile the tumors. And the Times article in the above link has a nice graphic explaining the process, although it isn’t linkable.
