Gene expression ratio identifies risk of recurrence in breast cancer patients receiving tamoxifen
... and its receptor protein, is used to treat breast cancers
that express the estrogen receptor. However, only two thirds of these patients have a prolonged response to the drug. "Until now, there has been no way to predict which estrogen-receptor-positive patients will not respond to tamoxifen treatment," say...
Why lung cancer in women is different from men

Molecular marker predicts success of breast cancer treatment
...a examined the gene expression levels in 60 breast cancers
from patients who were treated with tamoxifen after their surgery. Measuring gene expression is a way to examine whether or not a gene is functioning. They discovered that the ratio of the expression levels of two genes, HOXB13 and IL17BR, accurately...

Gene expression profiling may predict head, neck cancer recurrence
...d and neck tumors account for more than 40,000 new cancers
annually in the United States. The most common of these is squamous cell carcinoma. Prognosis is based largely on location and size of the tumor, and if the cancer has spread, or metastasized, to lymph nodes and distant sites in the body. The study i...
