The theme of my research is on the biology of cancers, in particular the utility of biological markers of malignancy. Histopathological examination is currently still the gold standard for cancer diagnosis. However, biological markers are playing an increasingly important role in cancer management. Understanding the biological profiles of a cancer would better define its natural and clinical history, and consequently, the likely course of the disease. In this regard, a major focus of my group is to investigate biological markers as prognostication factors and in the prediction of survival and response to therapy. Better characterization of individual patient’s prognosis could aid in clinical management and enable insightful personal decision-making.
