ABSTRACT
BACKGROUND/AIM: The global impact of the COVID-19 pandemic resulted in disruptions to healthcare systems throughout the world. The numbers of cytology examinations, human papillomavirus (HPV) tests, and women referred for colposcopy decreased in many countries. There have been no reports on cervical cancer screening in Germany. This study aimed to describe changes in the numbers of colposcopies, cytology examinations, HPV tests, and histological results during the pandemic compared to the pre-pandemic years in order to evaluate the impact of the COVID-19 pandemic on cervical cancer screening. PATIENTS AND METHODS: The numbers of colposcopies, cytology examinations, HPV tests, and histologic results were analyzed retrospectively for the period January 2018 to December 2022. The 2 years period before the pandemic (2018 and 2019) were compared with the 3 years period of the pandemic (2020-2022). RESULTS: In total, 6,518 colposcopies were performed in 5,579 women. The numbers of colposcopies, cytology examinations, and high-risk HPV (hrHPV) tests increased during the pandemic years. The number of biopsies per year taken was stable (range=450-554). The relative numbers of cervical intraepithelial neoplasia (CIN) III/HSIL findings were stable, while the numbers of cervical cancers identified increased slightly from 15 (6.6%) in 2018 to 22 (7.4%) in 2022. CONCLUSION: Increases in numbers of women examined and colposcopies were observed in the years 2021 and 2022 during the pandemic, in comparison to the preceding years. These also led to increases in the figures for cytology, hrHPV, histology, and operations. The onset of the pandemic occurred in the same year as a newly organized screening program started in Germany. The increases might therefore be due to the newly organized screening system.

Villoglandular adenocarcinoma (VGA) of the uterine cervix is a rare subtype of endocervical adenocarcinoma in young women. Between 2007 and 2020, all women with endocervical adenocarcinoma were retrospectively reviewed to find patients with VGA. Eight patients in whom pure VGA had been diagnosed were included. The mean age at initial diagnosis was 36.3 years (range 24-46). After surgical treatment, patients were followed up for 59 months (range 16-150). To date, all patients are alive with no evidence of disease. Neither lymph node involvement nor lymphovascular invasion was found. Furthermore, we examined the samples with a focus on morphological invasion pattern (Silva), stromal tumor-infiltrating lymphocytes (sTILs), and immunohistochemical programmed death ligand-1 (PD-L1) expression. PD-L1 expression was observed in 7/8 using the combined positive score (cutoff≥1%), 1/8 of VGAs using the tumor proportion score (cutoff≥1%), and 7/8 using the immune cell (cutoff≥1%). Using combined positive score and immune cell, PD-L1 expression was seen in 7/8 of pattern B and C tumors, with significantly higher expression in tumors with destructive-type patterns ( P <0.05, A vs. B+C). Using tumor proportion score, no significant difference in PD-L1 expression was seen between VGAs with different invasion patterns. VGAs demonstrated twice higher sTILs in tumors with destructive-type invasion patterns. Our observations suggest that PD-L1 expression, tumor invasion patterns, and sTILs do not correlate with the excellent prognosis of pure VGA.

(1) Background: Vaginal intraepithelial neoplasia (VaIN) is a rare premalignant disease caused by persistent human papillomavirus (HPV) infection. Diagnosing VaIN is challenging; abnormal cytology and positive HPV tests are usually the first signs, but published data on their accuracy for detecting it are rare and contradictory. The aim of this study is to compare the results of hrHPV and cytology co-testing with the histological findings of the vagina. (2) Methods: In the certified Dysplasia Unit at Erlangen University Hospital, cytology and HPV samples from the uterine cervix or vaginal wall after hysterectomy were obtained between 2015 and 2023 and correlated with histological findings in biopsies from the vaginal wall. Women without vaginal biopsy findings or concomitant cervical disease were excluded. (3) Results: In all, 279 colposcopies in 209 women were included. The histological results were: benign (n = 86), VaIN I/vLSIL (n = 116), VaIN II/vHSIL (n = 41), VaIN III/vHSIL (n = 33), and carcinoma (n = 3). Accuracy for detecting VaIN was higher in women with previous hysterectomies. Positive HPV testing during colposcopy increased the likelihood for VaIN II/III/vHSIL threefold. The detection rate for VaIN III/vHSIL was 50% after hysterectomy and 36.4% without hysterectomy. (4) Conclusions: Women with risk factors for VaIN, including HPV-16 infection or prior HPV-related disease, need careful work-up of the entire vaginal wall. Hysterectomy for HPV-related disease and a history of cervical intraepithelial neoplasia (CIN) also increased the risk for VaIN II/III/vHSIL.
ABSTRACT
Introduction Gynecologic dysplasia units and dysplasia consultations are obliged to offer diagnosis and treatment in accordance with the guidelines. The organization of the consultation process, management of patient appointments, diagnosis, and treatment algorithms are heterogeneous. The legislation arising from the new Federal Joint Committee decision, dated 22 November 2018, concerning the organized cervical cancer screening program has been in force since 1 January 2020. In this article we provide an overview of the existing structures and interdisciplinary cooperation of specialized dysplasia units incorporated in certified gynecologic cancer center. Materials and Methods We carried out a retrospective database search of data collected prospectively from 1 July 2014 to 31 December 2019 at the dysplasia unit at the Department of Gynecology and Obstetrics, Erlangen University Hospital, which was the first dysplasia unit to be certified in 2014. Results A total of 5594 patients presented at the unit, and 16061 colposcopic, vulvoscopic, and anoscopic examinations were performed. Approximately 4100 examinations of the cervix, vagina, vulva, and anus are carried out each year, 1600 of these were exclusively cervix colposcopies. A total of 12197 cytology results were assessed, as well as 4850 histology results, and 8193 high-risk HPV tests. The quality indicators required by the dysplasia unit for annual recertification were met each year. Conclusion Certified dysplasia units and consultations form the central component in the algorithm for further investigating abnormal screening results; but they are also the first point of contact for a large number of patients with acute or chronic complaints in the genital region.
ABSTRACT
BACKGROUND/AIM: The aims of the present study were to evaluate the accuracy of colposcopic findings, investigate the way in which untreated cervical intraepithelial neoplasia (CIN) 2/3 develops during pregnancy, and identify factors associated with regression, persistence, or progression rates. PATIENTS AND METHODS: In a tertiary gynecology and obstetrics department, 655 pregnant women were seen for colposcopy. The most common reason for referral was abnormal cytology findings. The follow-up findings were analyzed retrospectively on the basis of colposcopic findings and cytological and histological tests. RESULTS: The rate of accuracy for major colposcopic findings was 89.2%. Among the colposcopic findings considered "suspicious for invasion" were invasive carcinoma in 42.9% and CIN 3 in 57.1%. The persistence of CIN 3 postpartum was 80% and the rate of progression 4.1%. The rate of regression for CIN 3 was 21.9%. For CIN 2, the rate of persistence was 37.5%, with a regression rate of 31.3%. The rate of regression was higher after vaginal delivery in comparison with caesarean section. CONCLUSION: The accuracy rate of colposcopy is comparatively high, at 89.2%. This might be because pregnant women are seen by more experienced examiners in our dysplasia unit. The rate of progression is comparable with that in other studies. Vaginal delivery increases the regression rate. The newborns' birth weight or birth week did not affect the rates of regression or persistence.

PURPOSE: The aims of the present study were to evaluate the development of untreated cervical intraepithelial neoplasia (CIN) 3 during pregnancy and to assess persistence, progression, and regression rates postpartum to identify factors associated with regression. METHODS: In a tertiary gynecology and obstetrics department, a total of 154 pregnant women with CIN 3 were treated in the dysplasia unit. The follow-up findings were analyzed retrospectively on the basis of histological, cytological, and human papillomavirus (HPV) testing of 154 pregnant women confirmed as having CIN 3 in colposcopically guided biopsies. RESULTS: The rates of persistence, regression, and progression of CIN 3 in these women were 76.1%, 20% and 3.2%, respectively. Data for the delivery mode was available for 126 women. The rate of regression was almost twice as high with vaginal delivery as with cesarean section, at 27.4 vs. 15.2%, whereas the rate of progression was lower with vaginal delivery, at 2.7 vs. 6.5%. CONCLUSION: The rate of persistence of CIN observed in this study is comparable to that reported in other studies. The study provides strong evidence for greater regression among women who have vaginal deliveries. Careful work-up is recommended postpartum for this group of women in order to rule out persistent CIN 3 or invasive disease.

Background: The purpose of this research is to estimate the rate of concordance, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of colposcopy for high-grade squamous lesions and carcinomas (HSIL+). Methods: We conducted a retrospective study of colposcopies performed in the certified Dysplasia Unit in Erlangen between January 2015 and May 2022 (7.5 years). The colposcopic findings were correlated with biopsies obtained during examinations or surgery. Cases without histology were excluded. The primary outcome was the rate of concordance between the colposcopic and histological findings in relation to the type of transformation zone (TZ), examiner's level of experience and age of the patients. Results: A total of 4778 colposcopies in 4001 women were analyzed. The rates of concordance for CIN I/LSIL, CIN II/HSIL, CIN III/HSIL, and carcinoma were 43.4%, 59.5%, 78.5%, and 53.9%, respectively. The rate of concordance was lowest for TZ3 and highest for colposcopists with more than 10 years' experience. Conclusions: Colposcopy is an important, feasible, and effective method. Careful work-up needs to be performed for women with TZ3 who are over 35 years old, as they are at the highest risk of being misdiagnosed. The highest concordance for detecting HSIL+ was seen for colposcopists with >10 years' experience.
ABSTRACT
Background: A new nationwide screening strategy was implemented in Germany in January 2020. No data are available for women referred to certified dysplasia units for secondary clarification after primary diagnosis by a local physician. We therefore investigated combined testing with Papanicolaou smears and high-risk human papillomavirus (hrHPV) and compared the data with the final histological findings. Methods: Between January 2015 and October 2020, all referred women who underwent colposcopy of the uterine cervix in our certified dysplasia unit were included. Cytology findings were classified using the Munich III nomenclature. Results: A total of 3588 colposcopies were performed in 3118 women, along with Pap smear and hrHPV co-testing, followed by histology. Women with Pap II-p (ASC-US) and a positive hrHPV co-test had a 22.4% risk for cervical intraepithelial neoplasia (CIN) 3/high-grade squamous intraepithelial lesion (HSIL). The risk of CIN 3/HSIL was 83.8% in women with Pap IVa-p (HSIL) and a positive hrHPV co-test. A positive hrHPV co-test increased the risk for HSIL+ (OR 5.942; 95% CI, 4.617 to 7.649; p < 0.001) as compared to a negative hrHPV co-test. Conclusions: The accuracy of Pap smears is comparable with the screening results. A positive hrHPV test increases the risk for HSIL+ fivefold. Colposcopy is necessary to diagnose HSIL+ correctly.
ABSTRACT
BACKGROUND: Ovarian insufficiency is a major concern for long-term cancer survivors. Ovarian tissue cryopreservation for fertility preservation is an emerging technique that has proven successful over the past decade through transplantation of frozen-thawed ovarian tissue. Compared to other established techniques, such as oocyte freezing, ovarian tissue cryopreservation preserves actual organ function and thus the production of sex hormones. Endometriosis in perimenopausal women is rare, however it can be surprising diagnosis in the planned transplantation of cryopreserved ovarian tissue and the already thawed tissue may not be transplanted, so that it has to be refrozen. RESULTS: Ovarian function returned in the patient two months after transplantation, as shown by estrogen production. Ten months after the ovarian tissue transplantation mild stimulation with FSH was initiated in accordance with a low-dose protocol. When ultrasonography revealed a follicle 17 mm in size in the ovarian graft, hCG was added and after follicular puncture one oocyte was obtained. The oocyte could be fertilized by IVF and transferred to the uterus. On day 14 after embryo-transfer, a positive hCG-Level was detected and after an uncomplicated pregnancy a healthy child was delivered. CONCLUSIONS: We report the first pregnancy and live birth achieved using transplantation of thawed and refrozen ovarian tissue in a woman treated by chemotherapy and subsequent endometriosis surgery. Refreezing of cryopreserved ovarian tissue is not a hindrance to successful transplantation of ovarian tissue. Against the background of increasing numbers of candidates for transplantation of ovarian tissue is expected that the combination chemotherapy followed by endometriosis will increase.

PURPOSE: Villoglandular adenocarcinoma (VGA) of the uterine cervix has been classified as a rare subtype of cervical adenocarcinoma with good prognosis. A conservative surgical approach is considered feasible. The main risk factor is the presence of other histologic types of cancer. In this largest systematic review to date, we assess oncological outcomes associated with conservative therapy compared to those associated with invasive management in the treatment of stage Ia and Ib1 VGA. METHODS: Case series and case reports identified by searching the PubMed database were eligible for inclusion in this review (stage Ia-Ib1). RESULTS: A total of 271 patients were included in our literature review. 54 (20%) patients were treated by "conservative management" (conization, simple hysterectomy, and trachelectomy) and 217 (80%) by "invasive management" (radical hysterectomy ± radiation, hysterectomy, and radiation). Recurrences of disease (RODs) were found in the conservative group in two (4%) cases and in the invasive group in nine (4%) cases. There was no significant difference in disease-free survival (DFS) according to conservative or invasive treatment (p = 0.75). The histology of VGA may be complex with underlying usual adenocarcinoma (UAC) combined with VGA. CONCLUSION: The excellent prognosis of pure VGA and the young age of the patients may justify the management of this tumor using a less radical procedure. The histological diagnosis of VGA is a challenge, and pretreatment should not be based solely on a simple punch biopsy but rather a conization with wide tumor-free margins.

OBJECTIVE: Cervical cancer is caused by persistent infection with high-risk human papillomavirus (hrHPV). Cytology-based national screening programs have reduced the incidence and mortality of cervical cancer. Different hrHPV subtypes have different carcinogenic potentials. This study evaluated the distribution of different types of hrHPV relative to age in cervical cancer and its precursor lesions. METHODS: HPV testing was performed between November 2018 and February 2020 using the Abbott RealTime high-risk HPV assay on an Abbott m2000sp instrument. This assay separately detects HPV-16, HPV-18, and a pool of 12 additional hrHPV types (HPV-31, -33, -35, -39, -45, -51, -52, -56, -58, -59, -66, and -68). RESULTS: The study included 652 women with HPV samples and biopsies of the cervix or histology samples obtained during surgery. In all, 30.8% (95% CI, 27.3-34.6%) were HPV-negative. Among HPV-positive women, HPV-16, HPV-18, and "HPV other" types were found in 33.5, 4.4, and 49.4%, respectively. Cervical intraepithelial neoplasia (CIN) 3/high-grade squamous intraepithelial lesions (HSILs) in women ≤ 34 years were positive for HPV-16 in 54.5% of cases and in those ≥ 35 years in 45.4% of cases. Among women with cervical cancer, 75.8% were infected with HPV-16 or had coinfection with HPV-16 and "HPV other". CONCLUSIONS: HPV-16 is the most common type of hrHPV in HSIL + lesions. It is more common in women diagnosed with CIN 3/HSIL who are aged ≤ 35 and is decreasing with age. Therefore, women age ≥ 35 with persistent infection with this type of hrHPV need careful surveillance, as they are at high risk of progression to cervical cancer.
