Abstract
INTRODUCTION AND HYPOTHESIS
The practice of histopathological assessment of the uterus following hysterectomy for benign indications including pelvic organ prolapse (POP) surgery is common and often routine. While pathology is not anticipated, the finding of pathology requiring further action is always a concern, in particular CIN (cervical intraepithelial neoplasia) or cervical/uterine malignancy. We aimed to perform a systematic review to understand the prevalence of actionable uterine and cervical pathology in hysterectomy specimens performed for POP.
METHODS
A literature search was performed in January 2020 of MEDLINE, Embase and CINAHL using the Healthcare Databases Advanced Search platform. Included studies reported CIN and/or uterine/cervical malignancy in histological assessment of hysterectomy specimens performed purely for POP. Meta-analysis of prevalence was performed using the MetaXL ( www.epigear.com ) add-in for Microsoft Excel.
RESULTS
Six hundred seventy-seven records were identified, out of which 34 studies were eligible. Overall prevalence (95% confidence interval [CI]) of endometrial cancer in 33 studies was 0.004 (0.003-0.006), I2 = 41%, number needed to treat (NNT) 1:250. Total actionable uterine pathology was 0.005 (0.003-0.006) in 33 studies, I2 = 35%, NNT = 1:200. Overall prevalence of cervical cancer in 19 papers was 0.001 (0.000-0.002), I2 = 18%, NNT = 1:1000. In 16 studies the overall prevalence of CIN was 0.013 (0.001-0.033), I2 = 95%, NNT = 1:77. Prevalence of total actionable pathology was 0.013 (0.006-0.0023), I2 = 86%, NNT = 1:77.
CONCLUSION
The risk of actionable pathology is low, but not negligible. The variation between populations is wide. The prevalence of finding such pathology supports the routine practice of sending all hysterectomy specimens performed for POP for histological assessment.
