OBJECTIVE: To evaluate predictor factors of persistent cytologic dysplasia and/or high-risk human papillomavirus (hrHPV) infection at 6-month follow-up and at 3-5 years during routine cervical smear testing.
METHODS: The present retrospective study included data from women treated for cervical dysplasia by large loop excision of the transformation zone (LLETZ) at Ipswich Hospital, UK, between January 1 and December 31, 2012. Age, parity, smoking, status of resection margins, and previous LLETZ treatment were evaluated by multivariate analyses.
RESULTS: There were 192 patients included in the study. There was no association between age (relative risk [RR] 1.0, 95% confidence interval [CI] 0.80-1.23; P>0.99), smoking (RR 1.12, 95% CI 0.79-1.59; P=0.516), or parity (RR 1.10, 95% CI 0.88-1.38; P=0.382) and abnormal cytology and/or persistent hrHPV infection at 6 months. There was an association between positive margins (RR 1.64, 95% CI 1.20-2.24; P=0.003), previous LLETZ (RR 3.48, 95% CI 1.69-7.15; P<0.001), and dyskaryosis and/or hrHPV infection at 6 months. Only previous LLETZ treatment remained associated with abnormal cytology and persistent hrHPV infection at 3-5 years (RR 6.37, 95% CI 3.56-11.3; P<0.001).
CONCLUSION: Clinical factors, including age, smoking, treatment history, and status of surgical margins, could help to determine the risk of dysplasia recurrence and facilitate patient follow-up based on risk stratification.
