Our study did not aim at comparing histopathology with PCR, as both methods have different advantages; thus, the histopathological method specifically analyzes a tumor area, serially sectioned, immunolabeled with the three anti-p16/HPV/Ki67 antibodies studied, thus being able to perform descriptive statistical studies, whereas molecular methods can detail whether the genome is episomal or integrated. This evidence concerns the gene MKI67 and neoplasm.
