Oral cancer (OC) is one of the most commonly diagnosed cancer types worldwide. In some developing countries it is a leading cause
of cancer death. Significantly, survival rates for OC patients have not improved for decades. To combat this, my group is working
to understand the molecular alteration events that drive tumor development and to identify new molecular tools that can be applied to
manage patients who present clinically with oral cancers and precancers. OC develops through a series of histological stages, beginning with
movement from hyperplasia to mild/moderate dysplasia (both representing low grade oral premalignant lesions [LG OPLs]), progressing
to severe dysplasia and carcinoma in situ (high grade [HG] OPLs), until finally becoming invasive cancer. While it is understood that this
progression results from an accumulation of molecular alterations, attempts to identify these alterations have met with limited success.
Using our expertise in the area of genomics and RNA biology, we are analyzing individual OC and OPL cases by integrative analysis of
alterations in DNA dosage, mRNA expression, miRNA expression, and DNA methylation. This approach is not only helping us determine
which molecular changes are critical for driving disease, yielding new knowledge regarding oral tumorigenic processes but also identifying
novel biomarkers of disease behaviour which will ultimately guide disease management.
