Cancer of the uterine cervix (CACX) is one of the most common carcinoma affecting women worldwide. During treatment, histologically lymph node (LN) metastasis and presence of HPV DNA in blood plasma act as a major prognostic factor. Despite the lack of apparent LN involvement, some early-invasive CACX patients have shown recurrences and poor survival. This is suggestive of undetected early dissemination of cancer cells characterized by presence of HPV DNA in histologically non-metastatic LNs which finally progresses into histologically visible metastasis...

Actinic keratosis (AK) is considered a premalignant form of skin cancer due to chronic sun exposure. In addition, human papilloma virus (HPV) has been advocated a role in the pathogenesis of this clinical condition. HPV proteins (mainly E6 and E7) seem to act synergistically with ultraviolet (UV) radiation in reducing the defensive mechanisms of keratinocyte apoptosis after UV damage. Data regarding the involvement of other viruses, i.e. human herpes viruses (HHV), in the pathogenesis of AK are so far controversial...

Persistent human papilloma virus (HPV) infection induces chronic inflammation resulting in human cervical cancer. However, the mechanisms underlying carcinogenesis via chronic inflammation remain largely unclear. We investigated the role of pro-inflammatory factors in epithelial-mesenchymal transition (EMT) and cancer stem cell-like (CSCL) characteristics of HeLa cells exposed to TNF‑α with or without TGF‑β. We then determined the role of NF-κB/Twist signal axis in the pathogenesis of cervical cancer...

BACKGROUND: High-risk human papillomavirus (HR-HPV) testing has become a preferred cervical cancer screening strategy in some countries due to its superior sensitivity over cytology-based methods for identifying cervical intraepithelial neoplasia of grade 2 or worse (CIN2+). Improved sensitivity has been accompanied by reductions in specificity and concerns regarding over-screening and over-treatment of women with transient or non-progressing HR-HPV infections. Triage of HR-HPV+ women to colposcopy is, thus, warranted for appropriate management and treatment...

BACKGROUND: Anal canal high-grade squamous intraepithelial lesion (HSIL) is the precursor to anal cancer. Immunocompromised patients are at increased risk and disease is usually within 3 cm from the anal verge. High-resolution anoscopy (HRA) with an 8-cm anoscope is used to identify and guide cautery treatment of HSIL. PURPOSE: We report three patients with a long-term history of ulcerative colitis (UC) treated with systemic immunomodulators who developed proximally located rectal HSIL...

BACKGROUND: Human papillomavirus (HPV) initiates cervical cancer, and continuous expression of HPV oncogenes E6 and E7 is thought to be necessary to maintain malignant growth. Current therapies target proliferating cells, rather than specific pathways, and most experimental therapies specifically target E6/E7. We investigated the presence and expression of HPV in cervical cancer, to correlate HPV oncogene expression with clinical and molecular features of these tumors that may be relevant to new targeted therapies...

Cytotoxic T lymphocyte dysfunction is frequently associated with PD‑L1/PD‑1 pathway activation, and is a principal obstacle in cancer therapy. In the present study, the mechanisms underlying the human papillomavirus (HPV)‑induced evasion of cervical cancer cells to the host immune system via the programmed death ligand  1/programmed death 1 (PD‑L1/PD‑1) signaling pathway was investigated. A significant increase in the expression of the HPV16E7 viral protein and PD‑L1 in cervical tissues was observed when compared with normal cervical tissues...

Verruciform xanthoma is a rare and benign condition predominantly affecting the oral cavity, but also skin and female anogenital mucosa. It can be flat, papular-warty or crateriform-cystic. Furthermore it can simulate HPV viral lesion such as condyloma and malignant neoplasia such as verrucous squamous cell carcinoma. An accurate diagnosis is important to avoid overtreatment, considering it is a benign lesion that does not require any radical treatment. We present an extremely rare case of a 64 year-old man with a small, slighty raised, gray reddish-dotted lesion on the left portion of the ventral side of his glans...

BACKGROUND: Human Papillomavirus (HPV) infection is recognised as aetiological factor of carcinogenesis in oropharyngeal squamous cell carcinomas (OPC). HPV-related OPC respond better to treatments and have a significantly favourable outcome. Epithelial to mesenchymal transition (EMT) implicated in tumour invasion, is a hallmark of a poor prognosis in carcinomas. METHODS: We have studied the relationship of EMT markers (E-cadherin, β-catenin and vimentin) with HPV infection (DNA and E6/E7 mRNA detection), p16(INK4a) expression and survival outcomes in a cohort of 296 patients with OPC...

OBJECTIVE: Human papillomavirus (HPV) DNA testing is used increasingly for measuring the outcome of treatment for high-grade cervical intra-epithelial neoplasia (CIN2+). However, there is no international consensus regarding the number of tests and follow-up visits necessary in the post-treatment surveillance. A negative HPV DNA test result may permit relaxing the intensive post-treatment surveillance, but this possibility has not been standardized by all institutions to date. STUDY DESIGN: In 2008, the surveillance programme covering the Emilia-Romagna region in northern Italy adopted the HPV DNA test as a routine tool in the follow-up of women treated for CIN2+...

BACKGROUND: Human papillomavirus (HPV) is an important cause of head and neck squamous cell carcinoma (HNSCC), especially in young people. These tumours overexpress p16 and respond well to treatment. The rapid detection of HPV in patients with HNSCC may expedite treatment when p16 status is not immediately available. METHODS: Saliva-based DNA collection kits and nested polymerase chain reaction (PCR) were used to determine the HPV status of 62 individuals with biopsy-proven HNSCC...

BACKGROUND: The use of thermocoagulation for the treatment of cervical precancerous lesions has recently generated a great deal of interest. Our aim was to determine the feasibility of this outpatient procedure in the context of a cervical cancer (CC) screen-and-treat campaign in sub-Saharan Africa. METHODS: Between July and December 2015, women living in the area of Dschang (Cameroon) aged between 30 and 49 years, were enrolled in a CC screening study. HPV self-sampling was performed as a primary screening test and women who were either "HPV 16/18/45-positive" or "positive to other HPV types and to VIA" were considered screen-positive, thus requiring further management...

BACKGROUND: Cervical cancer is the most prevalent cancer among Peruvian women. Female sex workers (FSW) in Peru are at elevated risk for HPV infection, and receive annual Papanicolaou screening. The objective of this study was to identify barriers to follow-up for abnormal Pap smears among FSW in Peru. METHODS: 97 FSW attending the Alberto Barton Health Center in Lima were surveyed regarding their STI screening history. 17 women with a history of an abnormal Pap smear were interviewed about their experiences regarding follow-up care...

Human immunodeficiency virus (HIV)-infected patients are at an increased risk of co-infection with human papilloma virus (HPV), and subsequent malignancies such as oral cancer. To determine the role of HIV-associated immune suppression on HPV persistence and pathogenesis, and to investigate the mechanisms underlying the modulation of HPV infection and oral cancer by HIV, we developed a mathematical model of HIV/HPV co-infection. Our model captures known immunological and molecular features such as impaired HPV-specific effector T helper 1 (Th1) cell responses, and enhanced HPV infection due to HIV...

As the human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma epidemic has developed in the past several decades, it has become clear that these tumors have a wide variety of morphologic tumor types and features. For the practicing pathologist, it is critical to have a working knowledge about these in order to make the correct diagnosis, not to confuse them with other lesions, and to counsel clinicians and patients on their significance (or lack of significance) for treatment and outcomes...

The carcinogenic role of high-risk human papillomavirus (HR-HPV) types in the increasing subset of vulvar intraepithelial neoplasia and vulvar cancer in young women has been established. However, the actual number of vulvar cancer cases attributed to HPV is still imprecisely defined. In an attempt to provide a more precise definition of HPV-driven vulvar cancer, we performed HPV-type-specific E6*I mRNA analyses available for 20 HR-/possible HR (pHR)-HPV types, on tissue samples from 447 cases of vulvar cancer...

Neuroendocrine tumors (NETs) are aggressive diseases developing from neuroendocrine cells that most frequently involve the gastro-entero-pancreatic tract and the lung, but more rarely are found in almost all body tissues. Limited biological and clinical data are currently available for NETs in uncommon sites, such as female genital tract. NETs represent 0.9% to 1.5% of the tumors of the uterine cervix. They are more likely to have lymph-vascular space invasion and lymph node involvement, and to develop local and distant relapses when compared with the mostly common cervical squamous cell carcinomas or adenocarcinomas...
