Post-conization follow-up is essential for women treated for cervical intraepithelial neoplasia (CIN). Historically, the "Test of Cure" has relied on both cytology and human papillomavirus (HPV) testing. However, a recent study indicates that HPV testing after conization may be sufficient as a stand-alone method for certain patients. This approach could streamline post-operative care and reduce resource requirements in clinical settings, particularly in resource-limited environments.
This retrospective study analyzed 473 women who underwent conization between 2020 and 2024. Researchers manually extracted data from medical records and pathology databases. They specifically looked at the rates of persistent or recurrent CIN1+ lesions during the follow-up period. Because the study focused on real-world clinical outcomes, the results provide practical insights for gynecological practice and surgical follow-up protocols.
The results showed that 11.6% of the participants experienced persistent or recurrent disease. Notably, the status of resection margins played a significant role. Women with involved margins had a 30.3% recurrence rate, whereas those with free margins had only 3.6%. Furthermore, HPV testing after conization demonstrated a high sensitivity of 93% and a negative predictive value (NPV) of 98.7%. When clinicians combined negative HPV results with free resection margins, both the sensitivity and NPV reached a remarkable 100%.
These findings suggest that for women with negative margins, cytology might be omitted from the initial follow-up. This shift could significantly lower costs and the burden on pathology departments. Consequently, primary HPV testing is becoming a more attractive option for post-treatment surveillance in Indian healthcare. However, for women with involved margins, a more intensive follow-up strategy remains necessary due to the significantly higher risk of recurrence.
Yes, according to the latest research, HPV testing alone is highly accurate for women with free resection margins. It offers a negative predictive value of nearly 100%, matching the traditional Test of Cure.
Involved resection margins significantly increase the risk of disease persistence or recurrence. Therefore, patients with positive margins require more rigorous surveillance, often including both cytology and HPV co-testing.
