INTRODUCTION AND HYPOTHESIS: The Manchester procedure is a successful operation to treat uterine prolapse. However, the influence on cervical cancer remains unknown. We hypothesized a lower risk of cervical cancer after the Manchester procedure.

METHODS: We included all Danish women undergoing the Manchester procedure during 1977-2018 (N = 23,935). Women undergoing anterior colporrhaphy (N = 51,008) were included as references due to comparable health-seeking behaviors. The study cohort is as previously described. We assessed the risk of cervical cancer mortality after the Manchester procedure versus anterior colporrhaphy using cumulated incidence plots and Cox hazard regressions. We applied Fisher's exact test to compare the distribution of histological subtypes after the operations.

RESULTS: Generally, few women were diagnosed with cervical cancer (0.1% after Manchester procedure and 0.2% after anterior colporrhaphy). After the Manchester procedure, the risk of cervical cancer was reduced (HR 0.60 [95% CI 0.39-0.94]). Furthermore, we found a slightly reduced risk of overall death (HR 0.96 [95% 0.94-0.99]), but no association regarding death due to cervical cancer (HR 0.66 [95% 0.34-1.25]). The distribution of histological subtypes was not changed.

CONCLUSIONS: Women undergoing the Manchester procedure are at lower risk of being diagnosed with cervical cancer, while the risk of cancer specific mortality is unchanged compared to women undergoing anterior colporrhaphy. Based on this study, we cannot recommend that women exit ordinary screening programs for human papillomavirus/cervical dysplasia after a Manchester procedure.
