Cervical Cancer Screening: Is the Age Group 30-65 Years Optimum for Screening in Low-Resource Settings?

backgroundAn Operational Framework document for population-wide screening of common cancers in India was launched in 2016. The target age for screening is 30-65 years for cervical, breast and oral cancers. This study was designed to review the frequency and distribution of cervical lesions among women aged 21-29, 30-65 and > 65 years. STUDY

designA retrospective review of all satisfactory cervical smears (

resultsOf the 1357 ECAs (1.7% of all smears), about 16.9% were seen in the age band 21-29 years, while 4.5% presented in > 65 years of age. About 80% of the ECAs seen in younger women were low-grade squamous lesions, while 75% of lesions in women > 65 years were high-grade squamous abnormalities. Among the total 512 significant high-grade and malignant (squamous and glandular) lesions, 5.6% presented in women 21-29 years, while 10.1% were seen in > 65 years of age.

conclusionMajority of the significant cervical lesions would be detected if the screening focuses on the 30-65 years age group. However, about 19% of high-grade squamous preneoplastic lesions (ASC-H/ HSIL) and 13% of preneoplastic glandular lesions (AGC-N) are likely to be missed if women 21-29 years and > 65 years are excluded. The cost of screening incurred by including these age groups has to be weighed against the benefits derived, especially in low-resource settings. In the absence of universal implementation of HPV immunization, there is a felt need to enhance cervical cancer awareness and encourage screening, more so in high-risk category and symptomatic females beyond the selected age group.
