Post-conization endocervical curettage for estimating the risk of persistent or recurrent high-grade dysplasia

The value of endocervical curettage during large loop excision of the transformation zone in combination with endocervical surgical margin in predicting persistent/recurrent dysplasia of the uterine cervix: a retrospective study

BACKGROUND

Cervical cancer often originates from cervical cell dysplasia. Previous studies mainly focused on surgical margins and high-risk human papillomavirus persistence as factors predicting recurrence. New research highlights the significance of positive findings from endocervical curettage (ECC) during excision treatment. However, the combined influence of surgical margin and ECC status on dysplasia recurrence risk has not been investigated.

METHODS

In this retrospective study, data from 404 women with high-grade squamous intraepithelial lesions (HSIL) who underwent large loop excision of the transformation zone (LLETZ) were analyzed. Records were obtained retrospectively from the hospital's patient database including information about histopathological finding from ECC, endocervical margin status with orientation of residual disease after LLETZ, recurrent/persistent dysplasia after surgical treatment and need for repeated surgery (LLETZ or hysterectomy).

RESULTS

Patients with cranial (= endocervical) R1-resection together with cells of HSIL in the ECC experienced re-surgery 17 times. With statistical normal distribution, this would have been expected to happen 5 times (p < 0.001). The Fisher's exact test confirmed a statistically significant connection between the resection status together with the result of the ECC and the reoccurrence of dysplasia after surgery (p < 0,001). 40,6% of the patients with re-dysplasia after primary LLETZ had shown cranial R1-resection together with cells of HSIL in the ECC. Investigating the risk for a future abnormal Pap smear, patients with cranial R1-resection together with dysplastic cells in the ECC showed the greatest deviation of statistical normal distribution with SR = 2.6.

CONCLUSION

Our results demonstrate that the future risk of re-dysplasia, re-surgery, and abnormal Pap smear for patients after LLETZ due to HSIL is highest within patients who were diagnosed with cranial (endocervical) R1-resection and with cells of HSIL in the ECC in their primary LLETZ. Consequently, the identification of patients, who could benefit of intensified observation or required intervention could be improved.

Should attention be paid to the cone depth in the fully visible transformation zone? Retrospective analysis of 517 patients with cervical intraepithelial neoplasia grade 3

OBJECTIVE

The predictors of positive endocervical margin (EM) and a cone-depth cutoff value are not established in the fully visible transformation zone (TZ). The present study aimed to assess the independent variables associated with positive EM in women with high-grade cervical intraepithelial neoplasia (CIN) and fully visible TZ.

METHODS

The current investigation was a retrospective study including women with fully visible TZ and CIN 3 cone histology between 2014 and 2019. The sample was divided into women with positive versus those with negative EM. Univariate and multivariate analyses were performed. Finally, receiver operating characteristic curve analysis was also used.

RESULTS

A total of 123 of 517 women (23.8%) showed positive EM at conization. Multivariate analysis found a positive association with type 2 TZ (odds ratio [OR], 2.17 [95% confidence interval (CI), 1.19-3.94]) and lesion extension ≥2 cervical quadrants (OR, 35.57 [95% CI, 17.96-70.45]). Cone depth was inversely related to positive EM (OR, 0.71 [95% CI, 0.63-0.80]). In women with type 2 TZ and lesion extension ≥2 cervical quadrants, the cutoff value was achieved at 8-mm cone depth (area under the curve, 0.79 [95% CI, 0.67-0.90]).

CONCLUSION

In women with high-grade CIN and fully visible TZ undergoing conization, the lesion extension and the TZ subtype (1 or 2) should be considered. A no less than 9-mm cone depth provided a fair predictive value in achieving free EM.

Intraoperative Human Papillomavirus Test Predicts 24-Month High-Grade Squamous Intraepithelial Lesion Recurrence Saving Costs: A Prospective Cohort Study

OBJECTIVES

The human papilloma virus (HPV) test is recommended in the posttreatment follow-up of cervical intraepithelial neoplasia. The aim of the study was to assess whether the intraoperative HPV (IOP-HPV) test had a similar diagnostic accuracy that HPV test performed at 6 months to predict high-grade squamous intraepithelial lesion (HSIL) recurrence.

MATERIALS AND METHODS

In a prospective cohort study, 304 women diagnosed with HSIL by biopsy and/or endocervical curettage before treatment and/or confirmation in the histological specimen were included. Immediately after surgery, HPV testing was performed. This test was compared with the test at 6 months and other predictors of recurrence. Patients were followed for 24 months. An economic analysis was performed to compare the costs of IOP-HPV and HPV test at 6 months.

RESULTS

Recurrence rate of HSIL was 6.2% (19 patients). The diagnostic accuracy of the IOP-HPV test to predict HSIL recurrence at 24 months was similar to the HPV test at 6 months, with comparative sensitivities of 100% versus 86.7%, specificities of 82.0% versus 77.9%, positive predictive values of 27.1% versus 18.1%, and negative predictive values of 100% versus 99.0%. Direct economic saving per high-grade intraepithelial lesion patient was 172.8 &OV0556;.

CONCLUSIONS

The HPV test performed after loop electrosurgical resection procedure predicted recurrence of HSIL at 24 months with a similar diagnostic accuracy than the HPV test at 6 months. The use of the IOP-HPV test in the management of HSIL will allow early detection of the risk of recurrent disease and to save costs because of potential suppression of the need of HPV and follow-up controls at 6 months.
