Distribution of cervical lesions in young and older women

Abstract

Introduction: Age range for cervical screening varies widely between countries. In addition, sexual behavior has changed, life expectancy is increasing, and new insights have been gained into the pathogenesis of HPV infection. Our aim is to evaluate the distribution of cervical lesions in young and older patients.

Methods: Review of all cervical smears diagnosed in a public institution (2010-2017) and a private institution (2016-2017) in Madrid, Spain. We have included all women aged younger than 30 and older than 65 years with atypical smears (n = 1573).

Results: Women younger than 30 years were diagnosed with ASCUS, ASC-H, LSIL, and HSIL in 47%, 5.3%, 45.17%, and 2.6% of atypical cases, respectively. Women older than 65 years were diagnosed with ASCUS, ASC-H, LSIL, HSIL, and SCC in 38%, 12.39%, 16.8%, 13.27%, and 19.5% of atypical cases, respectively. Medical records of patients from the public institution were reviewed. Of note, 76.3% of young women showed negative smears at follow-up and 14.1% showed high-grade dysplasia (HGD). Mean ages for low-grade and HGD were 24.7 and 25.7 years, respectively. HGD was found in 37.9% of women with histological examination (33.5%). As for older patients, 25% of them had no Pap smears performed before age 65, and in 60% of the previously screened women, the screening program had not been used adequately. Mean age of first smear was 69.5 years. Carcinoma was subsequently detected in 20.7% of patients.

Conclusions: Current guidelines seem to be adequately preventing carcinoma in young women. However, screening adherence should be encouraged to detect important lesions in both age groups, especially among older women.
