Abstract
OBJECTIVES Evaluation of the results of treatment of adenocarcinoma in situ by loop electrosurgical excision procedure and the safety of a conservative strategy. METHODS Identification of all cases of adenocarcinoma in situ treated by loop electrosurgical excision procedure at our institution and follow-up by a conservative strategy. Completeness of the identification of all cases was secured by data from the National Pathology Registry. The treatment strategy was based on cytologic follow-up performed by a general practitioner and, irrespective of margin status of the cone, only the results of the postoperative surveillance were indicative of further treatment. RESULTS A total of 224 patients were identified. The overall recurrence rate with a mean follow-up time of 87.8 months was 7.6% (17/224). The recurrence rate in patients with involved margins was significantly higher than in patients with uninvolved margins, 15.7% vs 5.2%, respectively. Six recurrences were diagnosed at first examination 6 months postconization in patients with involved margins. They were treated with hysterectomy in 4 cases and reconization in 1 case. If involvement of margins alone had been an indication of further therapy (hysterectomy or reconization) immediately after conization, the conservative management strategy prevented 46 surgical procedures. Two cases of invasive cancer were diagnosed during follow-up, 150 months and 196 months after primary treatment, and after normal follow-up examinations. These 2 cases must be considered de novo cases and cannot be considered treatment failures. CONCLUSION The conservative management strategy thus seems safe, and unnecessary surgical procedures were avoided.

Abstract
Background Numerous studies have shown circular RNA (circRNA) dysregulation is associated with the pathogenesis of cervical cancer,particularly in individual carcinoma variants. The aim of this study is to investigate and contrastively analyze the expression pattern of circRNAs in cervical squamous carcinoma and adenocarcinoma mediated by human papillomavirus type 16 (HPV-16). Methods The expression of circRNAs in cervical squamous carcinoma (SCC), adenocarcinoma (ADC) and adenosquamous carcinoma (ASC) tissues, together with the adjacent normal tissues (ANT), was profiled by high-throughput RNA sequencing (RNA-seq). Bioinformatics analysis and quantitative real time polymerase chain reaction (qRT-PCR) validation of the sequencing data were performed. A network of circRNA-miRNA (microRNA)-mRNA was then constructed according to predicted targets and function of candidate circRNAs. Results A total of 11,685 annotated circRNAs were identified in six cervical samples. There were 42 up-regulated and 98 down-regulated circRNAs. 215 circRNAs were up-regulated in SCC but down-regulated circRNAs in ADC, while 50 circRNAs displayed the opposite trend. Function enrichment analysis based on different expressions of circRNAs found that the most enriched pathway in all the three pathologic variants of cervical cancer was the "ubiquitin mediated proteolysis" pathway. Eight key candidate circRNAs derived from this pathway were further validated, and we noticed that several target miRNAs of candidate circRNAs could target the source genes. Based on this we constructed a related competing endogenous RNA (ceRNA) network. Conclusion Through a comprehensive interpretation of differentially expressed circRNAs in different pathologic variants of cervical cancer, this study provides new insights into the process of tumor differentiation mediated by HPV. Our results may help to complement the molecular typing and stem cell theory of cervical cancer.

FOXP4 inhibits squamous differentiation of atypical cells in cervical intraepithelial neoplasia via an ELF3-dependent pathway. Cancer Sci 2022; 113:3376-3389.

Abstract
Although the human papillomavirus (HPV) vaccine is effective for preventing cervical cancers, this vaccine does not eliminate pre‐existing infections, and alternative strategies have been warranted. Here, we report that FOXP4 is a new target molecule for differentiation therapy of cervical intraepithelial neoplasia (CIN). An immunohistochemical study showed that FOXP4 was expressed in columnar epithelial, reserve, and immature squamous cells, but not in mature squamous cells of the normal uterine cervix. In contrast with normal mature squamous cells, FOXP4 was expressed in atypical squamous cells in CIN and squamous cell carcinoma lesions. The FOXP4‐positive areas significantly increased according to the CIN stages from CIN1 to CIN3. In monolayer cultures, downregulation of FOXP4 attenuated proliferation and induced squamous differentiation in CIN1‐derived HPV 16‐positive W12 cells via an ELF3‐dependent pathway. In organotypic raft cultures, FOXP4‐downregulated W12 cells showed mature squamous phenotypes of CIN lesions. In human keratinocyte‐derived HaCaT cells, FOXP4 downregulation also induced squamous differentiation via an ELF3‐dependent pathway. These findings suggest that downregulation of FOXP4 inhibits cell proliferation and promotes the differentiation of atypical cells in CIN lesions. Based on these results, we propose that FOXP4 is a novel target molecule for nonsurgical CIN treatment that inhibits CIN progression by inducing squamous differentiation.

Abstract
AIMS The dynamics and topographical distribution of SOX17 and SOX2 expression was studied in the transformation zone (TZ) of the uterine cervix. This TZ is a dynamic area where switches from glandular into squamous epithelium can be recognized, new squamocolumnar junctions are formed, and premalignant lesions originate. SOX17 and SOX2 show mutually exclusive expression patterns in the normal uterine cervix, with SOX2 being exclusively found in squamous epithelium, while SOX17 is detected in endocervical columnar cells and reserve cells. METHODS AND RESULTS Normal cervices and squamous intraepithelial lesions (SIL) were studied with immunohistochemistry, methylation of SOX17, human papilloma virus (HPV) genotyping, and in situ hybridization. In the TZ squamous metaplasia originating from these reserve cells can still show SOX17 expression, while also remnants of SOX17-positive immature metaplasia can be recognized in the normal squamous epithelium. SOX17 expression is gradually lost during maturation, resulting in the exclusive expression of SOX2 in the majority of (SIL). This loss of SOX17 expression is independent of methylation of the CpG island in its promotor region. HPV can be detected in SOX17-positive immature metaplastic regions in the immediate vicinity of SOX2-positive SIL, suggesting that switches in SOX17 and 2 expression can occur upon HPV infection. CONCLUSIONS This switch in expression, and the strong association between the distribution of reserve cells and squamous areas within the columnar epithelium in the TZ, suggests that reserve cell proliferations, next to basal cells in the squamous epithelium, are potential targets for the formation of squamous lesions upon viral infection.

Abstract
AIMS SOX17 expression has not been studied in glandular lesions of the uterine cervix like adenocarcinoma in situ (AIS) and invasive adenocarcinomas (AdC), whereas SOX17 promoter CpG island methylation has been reported. Therefore, the aim of this study was to relate the topographical distribution of SOX17 expression and SOX17 methylation status to each other, and to SOX2 expression, human papillomavirus (HPV) type, and physical status of the virus. METHODS AND RESULTS Immunohistochemistry was used in 45 cases to assess expression of SOX17 and SOX2. SOX17 promoter methylation was determined in 25 cases by means of bisulphite conversion and methylation-specific polymerase chain reaction. SOX17 and SOX2 showed a mutually exclusive expression pattern in normal epithelium, with a sharp delineation in the squamocolumnar junction. SOX17 was found in endocervical columnar and reserve cells, whereas SOX2 was exclusively found in squamous epithelium. In both glandular lesions and cases with coexisting glandular and squamous intraepithelial components, a complex combination of SOX17 and SOX2 expression patterns was seen and mutually exclusive expression was lost. Frequently, gain of expression of SOX2 was found and expression of SOX17 was lost. Methylation of the CpG island in the SOX17 promoter was shown to be strongly associated with loss of expression of SOX17 (P = 0.0016). CONCLUSIONS In this study, we show for the first time a direct correlation between the topographical distribution of SOX17 expression and the methylation status of its gene promoter. This explains the heterogeneity of SOX17 expression in the glandular lesions of the cervix. No correlation was found between HPV type and physical status of the virus on the one hand and methylation status on the other.

Abstract
The cervical squamocolumnar (SC) junction is the site of a recently discovered 'embryonic' cell population that was proposed as the cell of origin for cervical cancer and its precursors. How this population participates in cervical remodelling and neoplasia is unclear. In the present study, we analysed the SC junction immunophenotype during pre- and post-natal human and mouse development and in the adult, processes of metaplastic evolution of the SC junction, microglandular change, and early cervical neoplasia. Early in life, embryonic cervical epithelial cells were seen throughout the cervix and subsequently diminished in number to become concentrated at the SC junction in the adult. In all settings, there was a repetitive scenario in which cuboidal embryonic/SC junction cells gave rise to subjacent metaplastic basal/reserve cells with a switch from the SC junction positive to negative immunophenotype. This downward or basal (rather than upward or apical) evolution from progenitor cell to metaplastic progeny was termed reverse or 'top down' differentiation. A similar pattern was noted in high-grade squamous intraepithelial lesions (HSILs), suggesting that HPV infection of the cuboidal SC junction cells initiated outgrowth of basally-oriented neoplastic progeny. The progressive loss of the embryonic/SC junction markers occurred with 'top down' differentiation during development, remodelling, and early neoplasia. Interestingly, most low-grade SILs were SC junction-negative, implying infection of metaplastic progeny rather than the original SC junction cells. This proposed model of 'top down' differentiation resolves the mystery of how SC junction cells both remodel the cervix and participate in neoplasia and provides for a second population of metaplastic progeny (including basal and reserve cells), the infection of which is paradoxically less likely to produce a biologically aggressive precursor. It also provides new targets in animal models to determine why the SC junction is uniquely susceptible to carcinogenic HPV infection.

Abstract
Since the discovery of human papillomavirus (HPV) type 16 in early 80s, the link between HPV and cervical cancer has been established with certainty, a function of the discovery and cloning of a range of HPV types associated with both cancer precursors (cervical intraepithelial neoplasia or CIN) and carcinomas and extensive epidemiologic, clinical, pathologic, and experimental data. These accumulated results have culminated in new paradigms of cancer prevention through screening and triage. Despite this, the management of women with CIN is still suboptimal and the overtreatment of these conditions still occurs, largely due to the lack of clarity regarding which precancerous lesions are most likely to progress in grade. Recently, a discrete population of cuboidal cells was discovered at the cervical squamocolumnar junction, the anatomic site where the large majority of HPV-related (pre)neoplastic lesions develop. These cells seem to be embryonic in nature and participate both in benign metaplasias and the initial phase of precancer development. This review summarizes the historical evolution of precursor management, assesses the potential role of this and other discoveries in segregating lower from higher-risk precursors, and examines their potential impact on the management of women with real or potential cervical cancer precursors.

Abstract
We report a non-invasive mixed mucin-producing and squamous differentiated tumor of the uterine cervix. This tumor was composed of two cell types: mucin-producing cells and non-mucin-producing cells. These cells were intimately mixed with each other, and showed intraepithelial spreading. The mucin-producing cells showed signet-ring or columnar shapes, and were localized to the lower-to-upper epithelial layer. The non-mucin-producing cells had eosinophilic cytoplasms with a monotonous appearance through the epithelium. Mitosis was sometimes observed in both cell types. Immunohistochemically, both cell types were positive for p16(INK4A) . The non-mucin-producing cells were positive for p63 and 34βE12, suggesting squamous differentiation. Although most mucin-producing cells were p63(-) , a few of them were p63(+) and many 34βE12 immunoreactive cells were found in the mucin-producing cells. This tumor was adenosquamous carcinoma in situ.

Abstract
INTRODUCTION The adenocarcinoma of the uterine cervix accounts for 10 to 20% of the premalignant and malignant lesions and is different from the cervical intraepithelial neoplasia and invasive squamous cell carcinoma. MATERIALS AND METHODS Recent literature review (from 1985 to 2012) based on the literature available. RESULTS AND DISCUSSION Adenocarcinoma in situ is an induced HPV lesion (role of HPV 18) of the glandular epithelium: its preferential endocervical situation explains the difficulties in the diagnosis and follow-up after conservative treatment. If the hysterectomy remains the gold standard for treatment, the conservative treatments (resection in sano of the lesions with margins of more than 1cm, meticulous study of the operative specimen, compliance with the follow-up) are possible in the young patients who desire to preserve their fertility. The invasive adenocarcinoma is characterized by a more difficult diagnosis because of its endocervical development, and a prognosis less favorable when compared to squamous cell carcinoma with a greater frequency of the lymphatic node involvement and metastatic diffusion. Its treatment must take into account the particular gravity of the factors of worse prognosis (FIGO stage, tumor size, lymphatic node spreading, adenosquamous histological subtype) in particular in the advanced stages and includes beside the surgery, radiotherapy and chemotherapy.

Abstract
This overview summarizes pathogenetic and practical aspects of (sub-)classification of cervical glandular (pre-)neoplasias and, inter alia, calls into question the usefulness of grading. In the context of the differential diagnosis of benign "imitations", the phenotypic variability of glandular precancerous lesions and carcinomas is described as well as the use of special tests to distinguish them. With regard to carcinomas, the differential diagnosis of well-differentiated neoplasias is addressed including "minimal deviation" adenocarcinoma (MDA, malignant adenoma), carcinomas with endometrioid or villoglandular morphology, and mesonephric hyper- and neoplasias. Furthermore, knowledge of HPV-negative glandular (pre-)neoplasias is covered including "gastric-type" adenocarcinomas and diagnostic algorithms for discriminating between primary and secondary cervical adenocarcinomas. Finally, comments are offered on the difficulties in recognizing early invasive adenocarcinomas, especially also the pitfalls inherent in determining the depth of invasion.
