The human cervicovaginal microbiota resides at an interface between the host and the environment and may affect susceptibility to disease. Puerto Rican women have high human papillomavirus (HPV) infection and cervical cancer rates. We hypothesized that the population structure of the cervicovaginal bacterial and fungal biota changed with cervical squamous intraepithelial lesions and HPV infections. DNA was extracted from cervix, introitus, and anal sites of 62 patients attending high-risk San Juan clinics. The 16S rRNA V4 region and ITS-2 fungal regions were amplified and sequenced using Illumina technology...

PURPOSE: Prostaglandin-mediated inflammatory reactions play a major role in different cancers. Prostaglandin E2-receptor 3 (EP3) expression correlates with FIGO stages in cervical cancer and has been shown to be an independent prognostic factor for overall survival. EP3 expression levels in cervical intraepithelial neoplasia (CIN) as the precursor lesion of cervical cancer are currently unknown. METHODS: EP3 expression was analyzed by immunohistochemistry in 124 patient samples (CIN 1-3 and healthy controls) using the IR-scoring system...

OBJECTIVE: To develop an effective, low-cost, single-visit cervical screening strategy incorporating a modified Pap test and visual inspection with acetic acid and Lugol's iodine for low-income settings. METHODS: We conducted a prospective cohort trial. Two low-income Muslim Uyghur communities in China's far western Kashi Prefecture served as pilot and validation study sites, respectively, and 4,049 women (aged 30-59 years) were screened. The conventional Pap test was modified using a cotton swab to collect cervical cells without scraping the cervix using an Ayre spatula, allowing visual inspection with acetic acid (and visual inspection with Lugol's iodine if visual inspection with acetic acid was negative) to be performed in a single visit...

Despite the progress made in the reduction of squamous cell carcinoma of the cervix, the incidence of anal squamous cell carcinoma (ASCC) has been increasing since 1992. While it remains an uncommon disease, the prevalence is climbing steadily. Among human immunodeficiency virus (HIV)-infected adults, especially men who have sex with men, ASCC is one of the more common non-AIDS-defining malignancies. The precursor lesion, anal intraepithelial neoplasia (AIN), is prevalent in the HIV-infected population. More than 90% of ASCCs are related to human papilloma virus (HPV), oncogenic types (HPV 16, 18)...

The performance of different clinical screening algorithms comprising point-of-care HPV-DNA testing using self-collected vaginal ('V') specimens, and visual inspection of the cervix with acetic acid (VIA) was evaluated in Papua New Guinea. Women aged 30-59 years provided V specimens that were tested at point-of-care using the Xpert HPV Test (Cepheid, Sunnyvale, CA). A clinician-collected cervical ('C') specimen was then collected for point-of-care Xpert testing, and liquid-based cytology (LBC). Following this, VIA examination was conducted, blind to HPV test results, and ablative cervical cryotherapy provided if indicated...

Serous tubal intraepithelial carcinoma (STIC) has attracted attention as a precursor lesion of high-grade serous carcinoma (HGSC) of the ovary. We report the rare case of a woman in whom adenocarcinoma cells were detected in cervical smears and demonstrated to be derived from STIC in the fimbria. The patient was a 48-year-old woman, in whom cervical smears contained adenocarcinoma cells, but cervical conization did not reveal adenocarcinoma. Because the post-conization smears again demonstrated adenocarcinoma cells, hysterectomy with bilateral salpingectomy was performed 16 months after the first detection of adenocarcinoma cells in cervical smears...

BACKGROUND: High-risk human papillomavirus (hrHPV) detection and genotyping by Cobas HPV test has become an important technical platform in cervical cancer screening. It may be used as a co-test with cervical cytology or as a standalone test. Aptima HPV assay (AHPV) is another hrHPV test detecting 13 genotypes through qPCR based amplification of viral E6/E7 transcripts. Partial genotyping with Aptima HPV 16 18/45 genotype assay (AHPV GT) on positive samples is possible. Evidence supporting the performance of AHPV in Asian populations is scarce...

Identification of factors associated with human papillomavirus (HPV) cervical histopathology or recurrence/relapse following loop electrosurgical excision procedure (LEEP) would allow for better management of the disease. We investigated whether gene signatures could: a) associate with HPV cervical histopathology, and b) identify women with post-LEEP disease recurrence/relapse. Gene array analysis was performed on paraffin-embedded cervical tissue-isolated RNA from two cross-sectional cohorts of antiretroviral therapy (ART)-suppressed HIV+HPV+ co-infected women: a) 55 women in South Africa recruited into three groups: High risk (HR) (-) (n=16) and HR (+) (n=15) HPV without cervical histopathology, and HR (+) HPV with Cervical Intraepithelial Neoplasia (CIN) grade 1/2/3 (n=24); b) 28 women in Botswana with CIN2/3 treated with LEEP 12-month prior to recruitment and presenting with (n=13) and without (n=15) lesion recurrence/relapse (tissue was analyzed at first LEEP)...

Approximately 20-40% of high-grade Cervical Intraepithelial Neoplasia (CIN) regresses spontaneously, but the natural prognosis of an individual lesion is unpredictable. Gain of the chromosomal 3q region, which contains the human telomerase RNA gene on 3q26, is found in CIN lesions and cervical carcinoma and shows correlation with disease grade. The aim of this study is to assess whether 3q26 gain as a single genetic marker can predict the natural prognosis of high-grade CIN, by performing a review of the literature and pilot study...

INTRODUCTION: Screening of young women is often discouraged because of the high risk of unnecessary diagnostics or overtreatment. Multiple countries therefore use cytology instead of high risk human papillomavirus (hrHPV)-testing as screening method for young women because of the limited specificity of hrHPV-testing. The objective of this study was to investigate how hrHPV screening before the age of 30, can be used to reduce the future prevalence of high-grade cervical lesions in young women...

Tracy R Shachner, Stuart E Van Meter
Metastatic cancer involving the uterine cervix is exceedingly rare, and accounts for less than 1% of cancer deaths. The cervix is an uncommon location for metastatic lesions due to its limited blood supply and fibrous stroma and metastatic melanoma of the cervix is particularly infrequent. To the best of our knowledge and literature review, there have only been nine reported cases in the literature of metastatic melanoma involving the uterine cervix that were diagnosed via cervicovaginal Pap smears, including the case being reported in this paper...

BACKGROUND: In the present study, we primarily aimed to correlate the colposcopy results of patients with human papillomavirus (HPV) positivity and abnormal cervical screening results. Secondarily, we attempted to define the role of endocervical curettage (ECC) in the colposcopic evaluation of patients who had normal cytology and HPV16, which is the most carcinogenic HPV type. METHODS: This was a retrospective study analyzing the data of patients who had colposcopies between January 2015 and May 2016 in the Gynecological Oncology clinic of a single tertiary center...
