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: 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...

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...
