Though Atypical squamous cells of undetermined significance (ASCUS) are not always precursors of cervical pre-malignancy but they need timely diagnosis and careful periodical follow-up.
The present study was carried out to investigate the incidence of ASCUS and SIL (squamous intraepithelial lesion of cervix) in women under rural setting.
Materials and Methods
Cervical cancer screening is in progress in rural population of West Lucknow, India, since May 2013 under auspices of Era’s Lucknow Medical College and Hospital, Lucknow, and a total of 2478 women have been cytologically examined till October 2017.
The incidence of ASCUS was found to be 8.8%, which was approximately less than half of the squamous intraepithelial lesions of cervix (SIL) rate (17.9%). The ASCUS rate was higher in the symptomatic women (9.4%) than (7.4%) seen in women without symptoms. The ASCUS incidence was higher in younger sexually active group up to 40 years after which it declined. The ASCUS rate was higher in all parity groups and was commonly associated with pain in lower abdomen and vaginal discharge. The ASCUS rate was higher with erosion cervix, while the commonly associated sexually transmitted diseases (STD) were found to be Candida albicans (2.4%). Follow-up after 18–24 months was available in 40 cases of ASCUS, and progression to low-grade SIL (LSIL) was seen in 7 (17.5%) and to high-grade SIL (HSIL) in one case (2.5%).
The findings suggest that the ASCUS are not always precursors of SIL, but they need periodical follow-up after every 6 months. This will be ideal management of ASCUS under low-resource settings.
