Methods A total of 5664 CIN cases were reported using Metropolitan Lima Cancer Registry data. We calculated trends and predictions by tipe of CIN, age and socioeconomic level (quintile). Using software R.

Results Frecuency of CIN 2+ is 85.12%; CIN by age: < 21, 21–26, 26–50, 51–70 and >70 is 1.5%, 7.2%,75%,14% and 1.6% respectively. CIN by quintile (1 to 5) is 6%,13%,17%,36% and 25% respectively. During 2007–2010, CIN Trends remained stable for CIN 1 and CIN 2+, after that trends and predictions increasing for CIN 2+. During 2007–2010 (figure 1), CIN Trends by age remained stable, after that trends and predictions increasing for group between 26–50, however the extremes (<25 and >50) remain constant. During 2007–2010 (figure 2), CIN Trends by quintile remained stable, after that trends and predictions increasing for Q2-Q4, the increase is more important in the Q5 (figure 3).
