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...

BACKGROUND: The management of preinvasive cervical lesions has the objective to ensure the absence of invasive lesions and to prevent progression to cancer. Excisional procedures have been preferred to treat these lesions as they report the presence of unsuspected invasive lesions and the status of surgical margins, allowing inferring full excision when such are free of disease. The purpose of this study is to determine whether Straight Wire Excision of the Transformation Zone (SWETZ) is a better alternative than Large Loop Excision of the Transformation Zone (LLETZ-cone) as a type 3 excision of the Transformation Zone (TZ) to reduce incomplete excision and concerning other outcomes of surgical interest...

The aim of the present study was to determine the value of human papillomavirus (HPV) testing in screening patients with preinvasive cervical lesions. Seven hundred thirty-four women diagnosed with atypical squamous cells of undetermined significance (ASCUS+) cervical cytology during routine screening had additional cytologic testing and HPV DNA testing within 6 months of their diagnosis, after which all women who tested positive were referred for colposcopy and biopsy. The test findings were then used to determine the screening value of HPV for diagnosing preinvasive cervical lesions...

BACKGROUND: Cervical cancer (cca) is largely a preventable disease if women receive regular screening, which allows for the detection and treatment of preinvasive lesions before they become invasive. Having been inadequately screened is a common finding among women who develop cca. Our primary objective was to determine the Pap screening histories of women diagnosed with cca in Montreal, Quebec. Secondary objectives were to determine the characteristics of women at greatest risk of cca and to characterize the level of physician contact those women had before developing cca...

Cervical cancer is the second most prevalent malignancy among women worldwide, and additional objective diagnostic markers for this disease are needed. Given the link between cancer development and alternative splicing, we aimed to analyze the splicing patterns of the PRDX2, RAB1A, RAB1B, RAB5A and RAB25 genes, which are associated with different cancers, in normal cervical tissue, preinvasive cervical lesions and invasive cervical tumors, to identify new objective diagnostic markers. Biopsies of normal cervical tissue, preinvasive cervical lesions and invasive cervical tumors, were subjected to rapid amplification of cDNA 3' ends (3' RACE) RT‑PCR...
