We hypothesized that the extent of chromosomal aberrations reflects the duration of their existence. Chromosomal profiles were determined of CIN3 of women with a known 5\u2010year history of high\u2010risk human papillomavirus virus (hrHPV) infection, in which duration of prior hrHPV infection was considered a proxy for duration of CIN3 existence. Eleven women had a &lt;5 year preceding hrHPV infection (CIN3&lt;5yrPHI) and 24 had a PHI lasting \u22655 years (CIN3\u22655yrPHI). For comparison, six CIN3 adjacent to squamous cell carcinomas (CIN3\u2010SCC), the corresponding SCCs, and six CIN1 were included. Unsupervised hierarchical clustering analysis of the chromosomal profiles revealed two clusters. One was characterized by a low number of chromosomal aberrations and included all CIN1, 81.8% of CIN3&lt;5yrPHI and 33.3% of CIN3\u22655yrPHI. Samples in the second cluster, displaying multiple aberrations, included 18.2% of CIN3&lt;5yrPHI, 66.7% CIN3\u22655yrPHI, all except one CIN3\u2010SCC and all SCCs. The number of genomic aberrations increased according to lesion grade and also with longer duration of PHI. The increase in aberrations in CIN3\u22655yrPHI compared to &lt;5yrPHI was highly significant (<jats:italic>p<\/jats:italic> = 0.001), suggesting that CIN3\u22655yrPHI represent more severe lesions. In conclusion, longer duration of preceding hrHPV infection is associated with an increased number of chromosomal aberrations. Hence, CIN3 with a longer duration of existence are likely more prone to have an increased short\u2010term risk of cervical cancer.<\/jats:p>","DOI":"10.1002\/ijc.26496","type":"journal-article","created":{"date-parts":[[2011,10,23]],"date-time":"2011-10-23T04:18:52Z","timestamp":1319343532000},"source":"Crossref","is-referenced-by-count":34,"title":["Chromosomal
