Preinvasive cervical lesions

Lulu Sun, Lingxin Zhang, Hannah R Krigman, Ian S Hagemann
OBJECTIVES: Preinvasive squamous neoplasms of the lower genital tract are currently classified using a two-tier system (high- or low-grade squamous intraepithelial lesion) as directed by the Lower Anogenital Squamous Terminology (LAST) guidelines but may also be subclassified as intraepithelial neoplasia grade 1 (-IN1), -IN2, or -IN3. The LAST recommended that all diagnoses of -IN2 be supported by immunohistochemistry (IHC) for p16. We examined whether p16 and Ki-67 IHC are necessary to diagnose -IN2 when the lesion has obvious high-grade histology...

To date, no study has investigated the involvement of the single-nucleotide polymorphisms (SNPs) of WNT1 inducible signaling pathway protein 1 (WISP1) in uterine cervical cancer. Therefore, we conducted this study to explore the clinical implications of WISP1 SNPs in cervical cancer. One hundred and fifteen patients with invasive cervical cancer, 95 patients with preinvasive lesions, and 316 normal controls were enrolled. The WISP1 SNPs rs62514004, rs2929973, rs2977530, and rs2977537 were selected, and their genotypic distributions were determined through real-time polymerase chain reaction...

High-risk human papillomavirus (HPV) infection is known to be a necessary factor for cervical and anogenital malignancies. Cervical cancers account for over a quarter of a million deaths annually. Despite the availability of prophylactic vaccines, HPV infections remain extremely common worldwide. Furthermore, these vaccines are ineffective at clearing pre-existing infections and associated preinvasive lesions. As cervical dysplasia can regress spontaneously, a therapeutic HPV vaccine that boosts host immunity could have a significant impact on the morbidity and mortality associated with HPV...

BACKGROUND: Processes and mechanisms responsible for systemic immune suppression in early-stage cervical cancer remain substantially underinvestigated. In this work, we focused on studying the frequencies of circulating regulatory T (CD4 and CD8 Tregs) and NK (NKregs) cells in parallel with assessment of apoptotic markers expression in T cells from patients with preinvasive and microinvasive cervical cancer, with the aim to determine whether up-regulation of apoptosis-associated markers in Т lymphocytes accompanies cervical cancer development and correlates with the change in percentages of regulatory cell populations at systemic level during the initial stages of invasive cervical cancer progression...

A randomised controlled trial conducted in Mumbai, India, compared invasive cervical cancer rates among women offered cervical screening with invasive cervical cancer rates among women offered no-screening. The US Office for Human Research Protections determined the Mumbai trial was unethical because informed consent was not obtained from trial participants. Reportedly, cervical screening in the Mumbai trial reduced invasive cervical cancer mortality rates, but not invasive cervical cancer incidence rates. Documents obtained through the US Freedom of Information Act disclose that the US National Cancer Institute funded the Mumbai trial from 1997 to 2015 to study 'visual inspection/downstaging' tests...

RATIONALE: Patients with human immunodeficiency virus (HIV) infection have been shown to be at increased risk for high-risk human papillomavirus (HR-HPV) infection of the anogenital tract. Furthermore, in the last decades, the introduction of highly active antiretroviral therapy (HAART) has increased the longevity of these patients who now live long enough to develop HPV-related cancers; hence, the impact of HPV infection on HIV-positive patients is of increasing concern. PATIENT CONCERNS: We reported the case of an HIV-positive female patient on HAART with a good virological and immunological response and with a long history of HPV-related intraepithelial and invasive lesions of the anogenital tract...

BACKGROUND: Many strategies are required for cervical cancer reduction e.g. provision of education cautious sexual behavior, HPV vaccination, and early detection of preinvasive cervical lesions and invasive cancer. Basic health data for cervical cytology/ HPV DNA and associated factors are important to make an appropriate policy to fight against cervical cancer. AIMS: To assess the prevalence of abnormal cervical cytology and/or HPV DNA and associated factors, including sexual behavior, among Bangkok Metropolitan women...

BACKGROUND: High-risk Human Papillomavirus (HPV) testing is replacing cytology in cervical cancer screening as it is more sensitive for preinvasive cervical lesions. However, the bottleneck of HPV testing is the many false positive test results (positive tests without cervical lesions). Here, we evaluated to what extent these can be explained by cross-reactivity, i.e. positive test results without evidence of high-risk HPV genotypes. The patterns of cross-reactivity have been thoroughly studied for hybrid capture II (HC2) but not yet for newer HPV assays although the manufacturers claimed no or limited frequency of cross-reactivity...

Multifocal squamous cervical carcinomas account for up to 25% of IA1 tumors identified on excisional biopsy, yet there are no uniformly accepted histopathologic criteria for defining and staging these lesions. Here, we use a strict case definition and meticulous specimen processing from colposcopist to pathologist to identify and follow-up 25 cases of multifocal IA1 cervical squamous carcinomas identified in excisional biopsies. We stage these tumors using the dimensions of the largest focus and a minimum of 2 mm between each foci to define multifocality...

TLRs are important molecules of innate immune response, those play central role in host pathogen interaction and recognition through pathogen associated molecular patterns (PAMPs). Previous studies have indicated the role of TLRs in many human malignancy and cervical cancer in terms of viral recognition and inflammatory changes in-vivo. The objective of this study was to evaluate the expression and localization of toll-like receptor (TLR) 2 and TLR9 in preinvasive and invasive cervical cancer patients and to investigate its use as a probable diagnostic tool for better management cervical cancer...
