Tiling-set aCGH data for oral dysplasias and oral squamous cell carcinomas


ABSTRACT: Analysis of DNA from 89 oral lesions by whole genome tiling-path array comparative genomic hybridization. Keywords: array comparative genomic hybridization Genomic DNA isolated from 89 formalin-fixed paraffin-embedded oral dysplasias and tumors, then profiled by whole genome tiling-path array CGH to identify DNA copy alterations for each case.

Oral cancer develops through a series of histopathological stages: through mild (low grade), moderate, and severe (high grade) dysplasia to carcinoma in situ and then invasive disease. Early detection of those oral premalignant lesions (OPLs) that will develop into invasive tumors is necessary to improve the poor prognosis of oral cancer. Because no tools exist for delineating progression risk in low grade oral lesions, we cannot determine which of these cases require aggressive intervention. We  ...[more]
