Kate Coffey, Kezia Gaitskell, Valerie Beral, Karen Canfell, Jane Green, Gillian Reeves, Isobel Barnes
BACKGROUND: Vulval cancer predominantly affects postmenopausal women. A smaller proportion of vulval cancers, particularly at older ages, are now thought to be associated with human papillomavirus infection than previously reported, but other risk factors have not been well examined in prospective cohort studies. METHODS: A total of 1.3 million women aged 49-65 years were followed for incident vulval cancer (ICD-10 C51). Adjusted Cox regression models were used to examine the relationship between reproductive and lifestyle factors and risk of vulval cancer...

BACKGROUND: Light fractionation significantly increases the efficacy of 5-aminolevulinic acid (ALA) based photodynamic therapy (PDT) using the nano-emulsion based gel formulation BF-200. PDT using BF-200 ALA has recently been clinically approved and is under investigation in several phase III trials for the treatment of actinic keratosis. This study is the first to compare BF-200 ALA with ALA in preclinical models. RESULTS: In hairless mouse skin there is no difference in the temporal and spatial distribution of protoporphyrin IX determined by superficial imaging and fluorescence microscopy in frozen sections...

Cervical intraepithelial neoplasia (CIN) is the most common premalignant disease of the lower genital tract encountered during pregnancy. As in the non-pregnant state, abnormal cytology should be referred for colposcopy. However, the role of colposcopy in pregnant women is to exclude invasive cancer by visual inspection and defer biopsy and definitive treatment until the post-partum period. Colposcopic exclusion of invasive disease is the only absolute indication for conisation in pregnancy. It is now evident that treatment for CIN outside of pregnancy, that involves >15 mm deep excision is associated with an increased risk of preterm delivery...

BACKGROUND: Usual or undifferentiated type vulval intraepithelial neoplasia is more common in young women and is usually associated with high-risk human papilloma virus infection. It is associated with the development of basaloid or warty squamous cell carcinoma. Studies have shown that HIV-positive women have an increased risk of VIN and invasive vulval carcinoma but there is a paucity of data about this cohort of women. OBJECTIVE: To describe the clinical features and treatment response of HIV-positive women diagnosed with vulval intraepithelial neoplasia in a specialist vulval dermatology clinic...

BACKGROUND: This is an updated version of a review first published in theCochrane Database of Systematic Reviews, Issue 4, in 2011. Vulval intraepithelial neoplasia (VIN) is a pre-cancerous condition of the vulval skin and its incidence is increasing in women under 50 years. High-grade VIN (also called usual-type VIN (uVIN) or VIN 2/3 or high-grade vulval intraepithelial lesion) is associated with human papilloma virus (HPV) infection and may progress to vulval cancer, therefore is usually actively managed...

OBJECTIVES: Focused ultrasound waves penetrate superficial tissues and are aimed toward the target tissues at specific depths to exert their biological effects. Focused ultrasound has been applied for a number of clinical indications, including vulval dystrophies and low-grade vulval disease. This study aimed to assess the efficacy and safety of focused ultrasound treatment of high-grade vulval intraepithelial neoplasia (VIN). METHODS: Eighteen women with high-grade VIN were recruited and treated with focused ultrasound...

BACKGROUND: Vulval intraepithelial neoplasia is a skin disorder affecting the vulva that, if left untreated, can become cancerous. Currently, the standard treatment for patients with vulval intraepithelial neoplasia is surgery, but this approach does not guarantee cure and can be disfiguring, causing physical and psychological problems, particularly in women of reproductive age. We aimed to assess the activity, safety, and feasibility of two topical treatments--cidofovir and imiquimod--as an alternative to surgery in female patients with vulval intraepithelial neoplasia...

BACKGROUND: Methylation of HPV16 DNA is a promising biomarker for triage of HPV positive cervical screening samples but the biological basis for the association between HPV-associated neoplasia and increased methylation is unclear. OBJECTIVES: To determine whether HPV16 DNA methylation was associated with viral integration, and investigate the relationships between viral DNA methylation, integration and gene expression. STUDY DESIGN: HPV16 DNA methylation, integration and gene expression were assessed using pyrosequencing, ligation-mediated PCR and QPCR, in biopsies from 25 patients attending a specialist vulval neoplasia clinic and in short-term clonal cell lines derived from vulval and vaginal neoplasia...

OBJECTIVES: To assess the suitability and effectiveness of photodynamic therapy (PDT) in the treatment and symptom relief of vulval intraepithelial neoplasia (VIN), other pre-malignant and early neoplastic conditions of the vulva in an out patient setting. METHODS: Patients were selected from the vulvoscopy clinic whilst being investigated or under long-term follow-up. PDT was offered to patients in whom other treatments had failed or were unsuitable. 5-Aminoleuvinic acid (5-ALA) was used as a topical pro-drug, inducing the photosensitiser protoporphyrin IX...

Vulval intraepithelial neoplasia is a precursor of vulval cancer and is commonly caused by infection with Human Papillomavirus (HPV). Development of topical treatments for vulval intraepithelial neoplasia requires appropriate in vitro models. This study evaluated the feasibility of primary culture of vulval intraepithelial neoplasia biopsy tissue to produce cell lines for use as in vitro models. A potentially immortal cell line was produced which gave rise to three monoclonal lines. These lines were characterized for HPV genomic integration and for viral gene expression using ligation-mediated PCR and quantitative PCR...

The occurrence of ectopic intestinal/enteric-type epithelium at the vulva is a rare entity sometimes mimicking intraepithelial neoplasia or malignant disease. Here, we report a case of an 82-yr-old woman with a long-standing (10 yr) white papillary lesion with some reddish areas at her left labium, extending into the vaginal introitus. Biopsy reports revealed colonic-type glandular epithelium with positive immunostaining against CDX-2, p53, CK 7, and CEA, whereas staining against estrogen and progesterone receptor, mammoglobin, GCDFP-15, and CK 20 was reported to be negative...

BACKGROUND: This is an updated version of an original Cochrane review published in The Cochrane Library, 2011, Issue 1.Vulval intraepithelial neoplasia (VIN) is a pre-malignant condition of the vulval skin. This uncommon chronic skin condition of the vulva is associated with a high risk of recurrence and the potential to progress to vulval cancer. The condition is complicated by its multicentric and multifocal nature. The incidence of this condition appears to be rising, particularly in the younger age group...

BACKGROUND: It is unclear whether L1-VLP-based human papillomavirus (HPV) vaccines are efficacious in reducing the likelihood of anogenital pre-cancer in women with evidence of prior vaccine-type HPV exposure. This study aims to determine whether the combined results of the vaccine trials published to date provide evidence of efficacy compared with control (hepatitis A vaccine/placebo). METHODS: A systematic review and meta-analysis was conducted. Randomized-controlled trials (RCTs) were identified from MEDLINE, Embase, Web of Science, PubMed, Cochrane Central Register of Controlled Trials and references of identified studies...

Spindle cell or sarcomatoid squamous cell carcinoma is an uncommon variant of squamous cell carcinoma of the vulva (SCCV) with only 12 well-documented cases reported to date. Morphologically tumors may be biphasic or monophasic, and uncommonly include heterologous elements. Only 1 reported vulval tumor has previously been investigated for human papillomavirus DNA content. We describe 4 women with spindle cell (sarcomatoid) SCCV, 3 of which occurred de novo and 1 followed radiotherapy for previous SCCV. The tumors in all 4 women arose in a background of lichen sclerosus, and 3 were associated with vulval intraepithelial neoplasia differentiated (simplex) type...

For preinvasive lesions of vulva, a common term VIN -  vulval intraepithelial neoplasia is used. VIN is a histological dia-gnosis based on abnormal squamous epithelial proliferation. There are two types of VIN apart from their association with human papillomavirus (HPV). Undifferentiated (usual) vulval intraepithelial neoplasia is commonly associated with carcinogenic genotypes of HVP, whereas differentiated vulval intraepithelial neoplasia is not associated with high-risk genotypes of HPV. The article presents an overview of VIN occurence and epidemiology, its classification system and dia-gnostics...
