Oral Squamous Cell Carcinoma (OSCC) is the sixth most common malignancy in Australia. The five-year survival rate after diagnosis is 50%.
Early diagnosis of oral cancer remains a big challenge,histopathological assessment has been shown to not be ideal for predicting how particular
oral lesions will behave in the future.
MicroRNA are noncoding RNAs 19-22 nucleoties in length. They play a role in controlling gene expression and have been of interest in
association with oral mucosal disease including malignancy. The hypothesis of this research is that changes in microRNA levels will be
predictive of the malignant potential of oral mucosal conditions.
MicroRNA can be collected from epithelial cells and extracellular vesicles found in saliva.
To assess for variation in microRNA levels, 150 patients who are receiving a mucosal biopsy for mucosal abnormalities in which malignancy may be a potential diagnosis
will be enrolled. Collection of patient characteristics will be completed by a verbal questionnaire and inspection of existing clinical records.
Epithelial cells will be collected using a dermatological curette and placed in RNAlater solution. Saliva will be collected by a 30 second
mouth swirl of deionized water.
The purpose of this study is to assess if a new method of analysing mouth samples has value as a clinical prognostic indicator for presentations
of mucosal disease with associated malignant potential. Further, establishment of a reproducible, noninvasive, time efficient collection method
of representative tissue will adjunct this clinical tool.
