(2013)Background: The HER2 gene has been established as a valid biological marker for the treatment of breast cancer patients with trastuzumab and probably other agents, such as paclitaxel and anthracyclines. The TOP2A gene has ...

Prognostic factors in patients with colorectal cancer receiving adjuvant chemotherapy or chemoradiotherapy: A pooled analysis of two randomized studies
Bamias, A. T.; Basdanis, G.; Xanthakis, I.; Pavlidis, Nicholas; Fountzilas, George (2005)Background. Although the TNM system is useful in predicting survival in resected colorectal cancer, heterogeneity within the same stages regarding prognosis exists. We are presenting a pooled analysis of prognostic factors ...
