BACKGROUND: Adenocarcinoma-in-situ (AIS) of the uterine cervix is a precursor to cervical adenocarcinoma and may co-exist with both adenocarcinoma and high-grade squamous dysplasia (cervical intraepithelial neoplasia (CIN) 2 and 3). Up to 60% of AIS lesions are detected incidentally following excisional biopsies performed for the treatment of CIN 2/3. To date there are no data regarding risk factors for persisting or progressive cervical neoplasia in these patients. OBJECTIVE: To investigate patient outcomes following incidentally detected cervical AIS after loop electrosurgical excision procedure (LEEP) or cold knife cone (CKC) biopsy performed for the treatment of high-grade cervical intraepithelial neoplasia (CIN)...

INTRODUCTION: Vaginal intraepithelial neoplasia (VAIN) is a pre-malignant lesion, potentially leading to vaginal cancer. It is a rare disease, representing less than 1% of all intraepithelial neoplasia of the female genital tract. Similar to cervical intraepithelial neoplasia (CIN), there are three different grades of VAIN. VAIN 1 is also known as a low-grade squamous intraepithelial lesion (LSIL), whereas VAIN 2 and VAIN 3 both represent high-grade squamous intraepithelial lesions (HSIL)...

OBJECTIVE: Glycogen synthase kinase 3β (GSK3β) is a pluripotent protein kinase involved in the development of cancers through regulation of numerous oncogenic molecules. Cyclin D1, an important regulator of G1 to S phase transition in various cells, is one of target proteins that GSK3β regulate. Our objective was to assess the expression of GSK3β and cyclin D1 in cervical neoplasm of different histologic grades and to identify their correlation in cervical carcinogenesis. METHODS: Immunohistochemical analysis of GSK3β and cyclin D1 was performed in a total of 137 patients with 12 normal, 62 cervical intraepithelial neoplasia (CIN) (31 CIN1 and 31 CIN3) and 63 invasive cancers including 56 squamous cell carcinomas and 7 adenocarcinomas...

Cervical cancer screening based on the Papanicolaou (Pap) test is a widely applied but not always efficient practice for detecting Human Papillomavirus (HPV) mediated lesions, partially due to a non-systematic and inadequate screening process. Our aim was to introduce an inexpensive easy-to-use direct screening platform for improved detection of abnormal cells indicative of underlying cervical neoplasia as well as persisting HPV infection. By employing a novel, efficient technique of laser-based micromachining, we achieved the fabrication of spatial grids on commercially available coverslips allowing visual segmentation of the slide for efficient screening...

BACKGROUND: Effects of photodynamic therapy (PDT) were tested with respect to immune cell stimulation in cervical intraepithelial neoplasia (CIN). METHODS: A patient with CIN received hexaminolevulinate (HAL) and subsequent PDT. These data were compared to a placebo PDT patient and a healthy HPV16-vaccinated donor. Isolation of peripheral blood mononuclear cells (PBMC) was performed before PDT and at 4 different time points after PDT. The proliferation of these PBMC was tested by [(3)H]thymidine incorporation following stimulation with control or HPV16-L1 peptides...

BACKGROUND: The integration of human papilloma virus (HPV) into host genome is one of the critical steps that lead to the progression of precancerous lesion into cancer. However, the mechanisms and consequences of such integration events are poorly understood. This study aims to explore those questions by studying high risk HPV16 integration in women with cervical intraepithelial neoplasia (CIN) and cervical squamous cell carcinoma (SCC). METHODS: Specifically, HPV integration status of 13 HPV16-infected patients were investigated by ligation-mediated PCR (DIPS-PCR) followed by DNA sequencing...

Human papillomavirus (HPV) is a DNA virus that infects epithelial cells and has been implicated in the development of cervical cancer. Few therapeutic strategies have been designed for the treatment of cervical intraepithelial neoplasia, a precursor of cervical cancer. In these early stages, the HPV E2 protein is the most important viral factor involved in viral gene expression and plays crucial roles during the vegetative viral cycle in epithelial cells. Papillomavirus E2 binds specifically to palindromic ACCN6GGT sequences, referred to as the E2 binding sites (E2BS), which are concentrated within the viral long control region, and which are responsible for regulation of the HPV protein's expression...

It is universally accepted that high-risk human papillomavirus (HR-HPV) is the cause of cervical dysplasia and cancer. More recently it has been shown that HPV is also a marker of clinical outcome in oropharyngeal cancer. However, contemporary information is lacking on both the prevalence of HPV infection in vulvar cancer (VSCC), its precursor lesion, vulvar intraepithelial neoplasia (VIN) and the influence of HPV-status on the prognosis of this malignancy. We have conducted a detailed population-based study to examine rates of progression of VIN to VSCC, type-specific HPV prevalence in vulvar disease and the influence of HPV status on clinical outcome in VSCC...

PURPOSE OF REVIEW: Anal cancer is a serious health problem in HIV-positive men who have sex with men, and precursor lesions, anal intraepithelial neoplasia, are well defined. Given the similarities with cervical cancer, screening for and treatment of anal intraepithelial neoplasia might prevent anal cancer. Screening programmes should meet the Wilson and Jungner criteria. We used these criteria to evaluate the current body of evidence supporting a screening programme for anal dysplasia...

Aberrant activation of the canonical Wnt pathway plays a significant role in cervical cancer (CC). However, limited data show the correlation between the cancer clinicopathological characteristics and the key molecules such as β-catenin and Wnt inhibitory factor 1 (WIF1). In this study, β-catenin and WIF1 expression were analyzed by immunohistochemistry for 196 patients with CC, 39 with cervical intraepithelial neoplasia (CIN), and 41 with normal cervical epithelium (NCE). Significant overexpression of β-catenin was detected in CC (67...

OBJECTIVE: The incidence of abnormal cervical cytology in pregnancy is similar to that reported for non-pregnant women. Furthermore, 1% of pregnant women annually screened for cervical cancer will be diagnosed with cervical intraepithelial neoplasia (CIN) of various degrees. For this reason, Pap smear should be performed in the first trimester of pregnancy. The persistence of HR-HPV infection is related to the development of CIN. However, the relationship between CIN and HR-HPV infection during pregnancy and postpartum can hardly be found...
