BACKGROUND: In cervical cancer screening programs, women with abnormal cytology and confirmation by biopsy are referred for colposcopy for histological evaluation.
METHODS: We characterized the presence and the genotype of HPV by Linear Array HPV genotyping assay in cytological samples collected from about 400 women undergoing conization, with reported high CIN grade after biopsy.
RESULTS: The most prevalent genotype was HPV 16, with an increasing presence depending on the severity of the CIN and with the highest incidence in the 26-35 age range. In the group of younger women (<25) we found the highest percentage of CIN3 (39.3%) and the lowest of CIN1 (17.9%). An increase of CIN1 with increasing age was observed. A different distribution of HPV presence was observed depending on CIN grade (P<0.001): CIN1 HPV negative samples were 46.3%, CIN2: 5.8% and CIN3: 1.4%. Interesting, in the analyzed cohort, we observed the presence of 30% of CIN1. Moreover, within CIN1, 85% of them were associated to negative HPV detection, this observation suggested that the detection of HPV presence may be useful to identify low CIN grade that should be reconsidered for surgical treatment.
CONCLUSIONS: These findings suggest implementing the protocol for the management of women with high risk precancer lesions, with a further HPV test before surgical treatment. The evaluation of HPV presence and genotype before conization might represent a useful tool in reducing or postpone the conization treatment.
