Topics Covered
- DNA microarrays and PCR can provide information about the biology of breast cancer, prediction of response and prognosis
- A molecular taxonomy of breast cancer has been proposed based on gene profiling
- Prediction of response is still inaccurate and further studies should be performed
- Several prognostic profiles have proved advantage over classical prognostic factors
- They could be used in the near future to select patients for adjuvant chemotherapy in breast cancer
