RESUMO
OBJECTIVE: Women diagnosed with cervical glandular intraepithelial neoplasia (CGIN) remain at risk of further pre-malignant and malignant disease and require rigorous post-treatment follow-up. We assess the effectiveness and safety of community cervical sampling follow-up in women treated for CGIN. METHODS: A retrospective study was conducted of women diagnosed with CGIN between April 1, 2013, and March 31, 2019, at Jessop Wing Colposcopy Unit, Sheffield, UK. RESULTS: Of 140 women diagnosed with CGIN, 76 had co-existing cervical intraepithelial neoplasia (CIN). Cytologists were significantly more likely to report glandular neoplasia in the absence of co-existing CIN, and high-grade dyskaryosis in its presence (Ps < 0.0001). Co-existing CIN was significantly more likely to be present with high or low-grade compared to normal colposcopy findings (P < 0.0001). The 6-month test of cure (TOC) was attended by 67% of women (84% within 12 months), and the 18-month post-treatment sampling by 52.5% of women (70% within 24 months). Colposcopy recalled 96% of women correctly for the 18-month sampling, but 20% of women undertaking primary care samples were incorrectly recalled at 3 years instead. CONCLUSIONS: When CGIN is diagnosed, two dates for recall should be provided at 6 and 18 months post-treatment to the Cervical Screening Administration Service and the centralised screening laboratory ensuring the 18-month post-treatment sample is correctly appointed, preventing women with HPV-negative TOC samples being returned to 3-year recall. Follow-up of CGIN should be closely audited by the centralised laboratories ensuring women with CGIN are not put at additional risk.
