OBJECTIVES The risks of adenocarcinoma in situ (AIS) recurrence or progression after conservative treatment are uncertain. The aim of this study was to examine the role of high-risk human papillomavirus (hrHPV) and cytology in the posttreatment surveillance of AIS patients. MATERIALS AND METHODS Follow-up results of hrHPV status, cytology results, and clinicopathological features of 207 patients were retrospectively analyzed, in whom AIS was initially treated by loop electrosurgical excision procedure (LEEP)/cone biopsy between September 2009 and June 2018. RESULTS Among 207 patients diagnosed AIS on LEEP/cone biopsy, 30.9% (64/207) had positive margins. Persistent/recurrent AIS rate was substantially higher in the patients with positive margins than in those with negative margins (47.2% vs 9.3%, p < .001). Of 74 patients with hrHPV surveillance, 17 (17/74, 23.0%) were found to have positive hrHPV and 4 (4/17, 23.5%) had the persistent/recurrent AIS regardless of margin status. On the contrast, no AIS were found in negative surveillant hrHPV patients (23.5% vs 0%, p < .001). Lastly, 27.8% patients (22/79) were reported atypical glandular cells on surveillant cytology, and 9 persistent/recurrent AIS cases were further identified on second biopsy or hysterectomy with a positive detection rate of 40.9%. CONCLUSIONS In this study, we concluded the positive margin on LEEP/cone biopsy in AIS patients was associated with a significantly greater risk of disease persistence or recurrence. The posttreatment surveillance by cytology and adjunct hrHPV would be an ideal strategy in predicting AIS persistence and recurrence, which will warrant further treatments.

OBJECTIVES Cervical stenosis can jeopardize adequate posttreatment cytologic follow-up of patients treated for high-grade cervical intraepithelial lesions. An impact on human papillomavirus (HPV) testing has not been described. MATERIALS AND METHODS We describe 2 patients with cervical stenosis, followed by cytology and HPV co-testing after excisions of high-grade cervical intraepithelial lesions. Each had 1 or more co-test "double-negative" results. Hysterectomies revealed unexpected cervical carcinomas. RESULTS In case 1, an 80-year-old woman with complete cervical stenosis and earlier high-grade squamous dysplasia presented with abdominal pain, nausea, and an enlarged uterus. Attempted endometrial biopsy was unsuccessful. Cytology and HPV tests 9 months earlier were negative. Hysterectomy revealed a cervical squamous carcinoma. In case 2, a 40-year-old woman followed conservatively after excision of endocervical adenocarcinoma in situ had 5 follow-up cytology and HPV co-tests. All were HPV negative. Elective hysterectomy revealed cervical adenocarcinoma. Both carcinomas tested HPV positive. CONCLUSIONS Cervical stenosis in women developing cervical cancer can cause misleading sampling and false-negative HPV test results.

This study assesses whether high-risk human papillomavirus (HPV) DNA test results from residual vial fluid of unsatisfactory liquid-based cytology(LBC) samples might provide useful information on disease risk.Patients with unsatisfactory imaged ThinPrep Pap test results and available Hybrid Capture 2 high-risk HPV results were identified at an academic women's hospital laboratory between July 1, 2005, and July 31, 2007. Follow-up repeat cytology results, HPV results, and available biopsy results were analyzed.Three hundred four patients with unsatisfactory cytology results and HPV test results were studied. Eleven (3.6%) of 304 tested positive for HPV DNA, and 293 tested HPV negative. Five (45%) of 11 HPV-positive patients had detectible low-grade squamous intraepithelial/cervical intraepithelial neoplasia 1 during a mean follow-up period of almost 6 months. Among 293 women with negative HPV results, only 1 case of cervical intraepithelial neoplasia 1 was identified during roughly the same follow-up period.A positive high-risk HPV result associated with an unsatisfactory ThinPrep Pap test result identified patients at risk for diagnosis of an undetected squamous intraepithelial/cervical intraepithelial neoplasia. Negative high-risk HPV results associated with an unsatisfactory LBC had high negative predictive value in this limited study. The overall low detection rate for significant disease on follow-up of all patients with unsatisfactory imaged LBC is similar to findings reported in another LBC study but differs from studies reporting increased risk for undetected disease in women screened with unsatisfactory conventional Pap smears.

Objectives Cervical adenocarcinoma in situ (AIS) is the precursor to adenocarcinoma, and early management will often prevent the occurrence of invasive adenocarcinoma. Conservative treatment with conization has been proposed for the initial treatment for cervical AIS. To evaluate the risk of residual/recurrent disease after conization, we investigated the long-term follow-up results for patients with cervical AIS treated by conization. Materials and methods One hundred thirty-six patients with a biopsy diagnosis of cervical AIS followed by conization were followed up with cytologic, histologic, and human papillomavirus testing. Results The rate of residual AIS in the following hysterectomy was significantly increased in patients with positive margins on the conization (48.6%, 17/35) compared to patients with negative margins (0/30). No significant disease was identified in patients treated by hysterectomy as primary treatment. More importantly, only 2 patients with conization as primary management had adenocarcinoma or focal AIS, respectively, during a long-term follow-up period (mean, 45 mo). However, one of them had positive margin on the conization and did not proceed to further treatment. The other one had negative margin on the conization but only had focal AIS on the hysterectomy. Human papillomavirus-positive rate showed no significant difference between patients treated by conization and patients treated by hysterectomy during the long-term follow-up. Conclusions Therefore, if a negative resection margin is achieved, conservative management with conization and careful surveillance is suitable for patients with cervical AIS and desire for future childbearing.

OBJECTIVE The significance of high-risk HPV (hrHPV) testing in the management of women with abnormal cervical Pap tests is well known. However, the data about the hrHPV detection and its significance in abnormal vaginal specimens are very limited. The purpose of this study was to assess the prevalence of hrHPV in women with abnormal vaginal smears. METHODS Our Copath database system was searched to retrieve all the vaginal Pap tests with adjunctive HC2 hrHPV DNA test performed between July 1, 2005, and July 30, 2009. The results of hrHPV were reviewed in different TBS 2001 categories, in different age groups, and in white and African American women. RESULTS During the study period, there were 1,320 vaginal ThinPrep Pap tests with adjunctive HC2 hrHPV, reported as atypical squamous cells of undetermined significance (n = 1,125), atypical squamous cells cannot rule out high grade (n = 36), low-grade squamous intraepithelial lesion (n = 148), and high-grade squamous intraepithelial lesion (n = 11). A positive hrHPV DNA result was obtained in a total of 387 cases (29.3%), which included 244 atypical squamous cells of undetermined significance (21.7%), 21 atypical squamous cells cannot rule out high-grade (58.3%), 113 low-grade squamous intraepithelial lesion (76.4%), and 9 high-grade squamous intraepithelial lesions (81.8%). Mean age was 56.5 years (range = 17-93 y). High-risk HPV-positive rate was 34.5% versus 24.9% in women aged 54 years or younger compared with those aged ≥ 55 years or older (p < .001) and 45.1% versus 27.3% in African American women compared with white women (p < .001). High-risk HPV DNA-positive rate was 2.6% among the 1,572 women with negative vaginal Pap tests. CONCLUSIONS Our results show that prevalence of hrHPV in abnormal vaginal smears parallels that of cervical smears with equivalent degree of abnormality. The suggestion of reflex hrHPV testing as a tool in formulating the management plan for women with abnormal vaginal smears needs further attention.
