Human papillomavirus type 16 (HPV16) is the major cause of cervical cancer and of a fraction of oropharyngeal carcinoma. Few studies compared the viral expression profiles in the two types of tumor. We analyzed HPV genotypes and viral load as well as early (E2/E4, E5, E6, E6*I, E6*II, E7) and late (L1 and L2) gene expression of HPV16 in cervical and oropharyngeal cancer biopsies. The study included 28 cervical squamous cell carcinoma (SCC) and ten oropharyngeal SCC, along with pair-matched non-tumor tissues, as well as four oropharynx dysplastic tissues and 112 cervical intraepithelial neoplasia biopsies...

Human papillomavirus (HPV), and the related, cervical intraepithelial neoplasia (CIN), are common yet poorly understood physical conditions. The diagnosis of HPV often elicits shame and guilt, which in turn may undermine psychological and physical health. The current study compared shame and guilt responses to diagnosis among two groups: women diagnosed with HPV/CIN and women diagnosed with Epstein-Barr Virus (EBV/IM). Eighty women recently diagnosed with HPV/CIN or EBV/IM completed measures of shame- and guilt-proneness, shame and guilt following diagnosis, and disease knowledge including prevalence estimates (HPV and EBV, respectively)...

Cervical cancer is the second most common cancer and the third leading cause of cancer death in females worldwide, especially in developing countries. High risk human papillomavirus (HR-HPV) infection causes cervical cancer and precancerous cervical intraepithelial neoplasia (CIN). Integration of the HR-HPV genome into the host chromatin is an important step in cervical carcinogenesis. The detection of integrated papillomavirus sequences-PCR (DIPS-PCR) allowed us to explore HPV integration in the human genome and to determine the pattern of this integration...

Gastric-type adenocarcinoma of the cervix (GAS) is an uncommon and aggressive tumour unrelated to human papillomavirus (HPV) infection with distinctive histological and immunohistochemical characteristics. GAS may be associated with lobular endocervical glandular hyperplasia (LEGH), another unusual lesion. We report a case of a 59-year-old woman with screening cytology 'AGC-Neo' and cervical conisation exhibiting cervical intraepithelial neoplasia grade 1, extensive LEGH and canal sampling with abundant mucinous cells...

OBJECTIVE: The aim of this study was to evaluate p16, cytokeratin 7 (CK7), and Ki-67 immunoexpressions in low-grade squamous intraepithelial lesion (LSIL), looking for differences among cases that progress to high-grade squamous intraepithelial lesion, maintain LSIL, or regress. MATERIALS AND METHODS: Sixty-six LSIL biopsies were studied. In the follow-up, a second biopsy showed 28.7% regression, 37.9% LSIL, and 33.4% progressed to high-grade squamous intraepithelial lesion...

OBJECTIVE: Numerous new alternative digital colposcopy techniques have been developed, of which multimodal hyperspectroscopy (MHS) showed a high sensitivity in previous studies. The objective of this prospective single-center cohort study was to evaluate the clinical value of MHS for detecting high-grade cervical intraepithelial neoplasia in a colposcopy referral population and colposcopy follow-up population, to assess whether MHS could be safely used to improve care for women at risk for high-grade cervical intraepithelial neoplasia...

Dysregulated expression of oncogenic types of E6 and E7 is necessary for human papillomavirus (HPV)-driven carcinogenesis. An HPV E6/E7 mRNA in situ hybridization (ISH) assay covering 18 common high-risk types ("HR-RISH," aka HR-HPV RNA18 ISH) has not been extensively studied in the anogenital tract or validated on automated technology. We herein compare HR-RISH to DNA polymerase chain reaction (PCR), p16 immunohistochemistry, and a previously available HPV DNA ISH assay in HPV-related anogenital and head and neck (H&N) neoplasia...

Despite the success of cervical screening, cancer of the cervix is the fourth most common cancer affecting women worldwide (CRUK 2014). Rates are particularly high in developing nations, which lack the requisite infrastructure for cytology and colposcopy-based screening, and in certain demographic groups, where uptake of screening is poor. Recent research has focussed on developing less invasive and potentially more acceptable means of identifying women at high risk of cervical intraepithelial neoplasia (CIN)...

Single-organ vasculitis (SOV) has rarely been reported to involve the female genital tract but mostly the uterine cervix. A 39-year-old woman was diagnosed to have a high-grade cervical intraepithelial lesion and was treated by large loop excision of the transformation zone. Histopathological evaluation of the excised specimen confirmed the diagnosis of cervical intraepithelial neoplasia grade III accompanied by human papillomavirus infection. The excised second specimen showed the evidence of vasculitis of medium-sized vessels of the cervix, which is a quite rare form of SOV...

Cervical cancer is strongly related to certain high-risk types of human papilloma virus infection. Breast cancer metastasis suppressor 1 (BRMS1) is a tumor suppressor gene, its expression being regulated by DNA promoter methylation in several types of cancers. This study aims to evaluate the methylation status of BRMS1 promoter in relation to high-risk types of human papilloma virus infection and the development of pre-cancerous lesions and describe the pattern of BRMS1 protein expression in normal, high-risk types of human papilloma virus-infected pre-cancerous and malignant cervical epithelium...

We describe here a case of high-grade vaginal squamous lesion in a 54-year-old woman with a papillomaviruses (HPV) genital infection that developed from a cervical low-grade squamous intraepithelial lesion (SIL) to a high-grade SIL (H-SIL) on cytological examination. A colposcopy exam led to the detection of suspect vaginal lesions with granulomatous infiltrations, which were classified as a Vaginal Intra-Epithelial Neoplasia grade 2 after pathologists' analyses. After a laser vaginal surgery and a loop excision of the transformation zone, the analyses of the anatomical pieces using a near-complete HPV screening panel revealed an HPV-4 infection that was not detected before in cervical smears...

Cytology-based cervical cancer screening is restricted because of a lack of cytologists. Thus, HPV-based instead of cytology-based screening may be a more suitable strategy in China. Here, we assessed the effectiveness of HPV testing (Cobas(®) 4800 Test, Roche) and HPV-based programs to detect high-grade cervical intraepithelial neoplasia (CIN) or cancer compared with cytology (Thinprep, Hologic) and cytology-based programs through a cross-sectional study in 11,064 Chinese women aged 21-65 years who were enrolled from Longyou County in Zhejiang Province, China...

BACKGROUND: P16/INK4a and Ki-67 have emerged as important biomarkers for the detection of high-risk human papilloma virus (HR-HPV) associated dysplastic changes in the cervical biopsy samples. The increasing inter- and intra-observer variability in the diagnosis of dysplastic lesions and immature squamous metaplasia on histopathology has led to the advent of these biomarkers. This study was taken up with an aim to study their role in increasing the diagnostic accuracy in equivocal cases on histopathology...

REVIEW
Karin Hellner, Lucy Dorrell
High-risk human papillomaviruses (hrHPV) are responsible for anogenital and oropharyngeal cancers, which together account for at least 5% of cancers worldwide. Industrialised nations have benefitted from highly effective screening for the prevention of cervical cancer in recent decades, yet this vital intervention remains inaccessible to millions of women in low- and middle-income countries (LMICs), who bear the greatest burden of HPV disease. While there is an urgent need to increase investment in basic health infrastructure and rollout of prophylactic vaccination, there are now unprecedented opportunities to exploit recent scientific and technological advances in screening and treatment of pre-invasive hrHPV lesions and to adapt them for delivery at scale in resource-limited settings...

The aim of this study was to explore the correlation of ezrin and galectin-3 expressions with prognosis in cervical cancer. The immunohistochemical method was applied to detect ezrin and galectin-3 expressions in normal cervix tissues (n=30), cervicitis tissues (n=28), cervical intraepithelial neoplasia (CIN) tissues (classified as I-III, n=89), and cervical carcinoma tissues (n=84). Follow-up was conducted for 5 to 78 months to analyze the correlation of protein expressions with prognosis. Ezrin and galectin-3 expressions in cervical cancer were significantly higher than in normal cervix, cervicitis and CIN (all P<0...
