Objective: Many patients undergo hysterectomy for the treatment of cervical dysplasia. Factors that correlate with residual high-grade squamous intraepithelial lesions (HGSIL) at hysterectomy are not clear. We set out to determine preoperative features that may predict residual disease for patients treated for cervical dysplasia.
Materials and methods: A retrospective database was reviewed for women who underwent simple hysterectomy for HGSIL between 1990 and 2013. Clinical data included age, history of dysplasia, initial treatment, follow-up colposcopy, indications for surgery, time elapsed between initial treatments, and pathology findings after hysterectomy. Significant residual disease was defined as HGSIL or cervical carcinoma. Statistical analyses were performed with the SPSS, independent Student t test, and Pearson χ test. Significance was set at p < .05.
Results: Eighty-three women met the study criteria. The indication for hysterectomy was residual histological finding at conization pathology in 30 women and patients' request in 53 women. Residual disease was found in 42 hysterectomy specimens: in 16 of 30 with residual histological finding and in 26 of the 53 patients' request. Reason for the hysterectomy was not statistically significant for residual disease (p = .708). Median age of patients with residual disease was 46.5 years versus 44.1 years for those without residua (p = .02). Postmenopausal patients had a higher rate of residual disease, 12 (32.4%) of the 28 premenopausal patients and 25 (67.6%) of the 54 postmenopausal patients (p = .04). Conization margin status was not associated with residual disease (p = .878).
Conclusions: Older women and those in menopause are at significantly higher risk of residual disease at hysterectomy.
