Increased frequency of abnormal Papanicolaou smears in adolescents.
Abnormal Papanicolaou smears has increased in adolescents. Our objective was to analyze the frequency of cervical intraepithelial neoplasia (CIN) in adolescents (< 20 years of age) over the last 12 years, comparing to adult (> or = 20 years of age). We studied 110,283 (10.85% of adolescents) reports from Papanicolaou smears between 1987 and 1999 in a public university hospital that has a screening program for cervical cancer prevention. The tests were divided into 3 periods (1987-1991, 1992-1995 and 1996-1999) for studying the evolution of frequencies. CIN I was more frequent among adolescents (1.73% vs. 0.99%) and CIN III and invasive cancer among adult women (0.62% vs. 0.05%, and 0.39% vs. 0.0083%, respectively). Between the periods 1987-1991 and 1996-1999 there was an increased in the frequency of CIN I among adolescents (from 0.78-2.17%) and adults (from 0.72-1.16%); CIN II decreased among adult patients (from 0.52-0.28%) and tripled among adolescents over recent years (from 0.15-0.47%), and CIN III increased in both group, although without statistical significance. One case of invasive carcinoma among adolescents occurred in the period from 1996-1999. We strongly recommend the inclusion of adolescent populations in the screening programs, from the time that they begin sexual activity.
