Endocervical adenocarcinoma in situ-from Papanicolaou test to hysterectomy: a series of 74 cases.

J Am Soc Cytopathol 2021 Aug 9. Epub 2021 Aug 9.

Department of Pathology, Rush University Medical Center, Chicago, Illinois. Electronic address:

Introduction: Endocervical adenocarcinoma in situ (AIS) is not always identified on cervical Papanicolaou (Pap) test cytology because the Pap test has relatively low sensitivity for the diagnosis endocervical glandular lesions. We performed a retrospective study to determine the relative sensitivity of different diagnostic approaches, including Pap tests, cervical biopsy and/or endocervical curettage, loop electrosurgical excision procedure (LEEP), and hysterectomy specimens.

Methods: Cases of endocervical AIS diagnosed from August 2005 to January 2019 were retrieved from our institution's pathology databases, and their clinicopathologic features were reviewed. Read More

Accuracy of combined molecular and morphology-based triage for HPV-positive women in routine cervical cancer screening services from Colombia.

Prev Med 2021 Sep 8:106801. Epub 2021 Sep 8.

Subdirección de Investigación - Instituto Nacional de Cancerología, Bogotá, Colombia. Electronic address:

WHO cervical cancer elimination goals comprise 70% of highly-sensitive screening coverage and 90% treatment of precancerous lesions. Triage for HPV-positive women may challenge sensitivity of screening algorithms and women's follow-up, particularly in low- and middle-income countries (LMIC) where screening quality and protocol adherence are frequently deficient. We aimed to determine the accuracy of triage for HPV positive women in routine screening services from Colombia by a prospective cross-sectional study. Read More

Inside the pocket: critical elements of HLA-mediated susceptibility to cervical precancerous lesions.

HLA 2021 Sep 10. Epub 2021 Sep 10.

Laboratory of Immunogenetics and Histocompatibility, Department of Genetics, Universidade Federal do Paraná (UFPR), Curitiba, Brazil.

Human papillomavirus (HPV) infection is a necessary cause for cervical cancer (CC), but it also depends on genetic factors, such as HLA polymorphism. However, few reports addressed the role of amino acids residues at the HLA peptide-binding cleft in HPV-related cervical disease. Therefore, we aimed to investigate the association between HLA-B, HLA-C, and HLA-DRB1 polymorphism and amino acid residues composing the pockets of the peptide-binding cleft of the respective polypeptide chains with cervical intraepithelial neoplasia (CIN II/III).

EDCs and male urogenital cancers.

Adv Pharmacol 2021 24;92:521-553. Epub 2021 Jun 24.

Environmental Chemical Pollution and Health Research Unit, Faculty of Health Sciences, School of Health Systems and Public Health, University of Pretoria, Pretoria, South Africa; Environmental Chemical Pollution and Health Research Unit, Faculty of Health Sciences, School of Medicine, Department of Urology, University of Pretoria, Pretoria, South Africa.

Male sex determination and sexual differentiation occur between 6-12 weeks of gestation. During the "male programming window" the fetal testes start to produce testosterone that initiates the development of the male reproductive tract. Exposure to endocrine disrupting chemicals (EDCs) able to mimic or disrupt steroid hormone actions may disrupt testicular development and adversely impact reproductive health at birth, during puberty and adulthood.

Evaluating the Performance of Hybrid Capture 2 Test as a Primary Screening Test from Studies Conducted in Low and Middle-Income Country Settings- Special Focus India.

Asian Pac J Cancer Prev 2021 Aug 1;22(8):2709-2716. Epub 2021 Aug 1.

Department of Health Disparities Research, Division of Cancer Prevention & Population Science, M.D Anderson Cancer Centre, Houston,USA.

Among the screening tests for cervical cancer, advantages of screening with second generation molecular Hybrid Capture 2 (HC2) test is the high sensitivity and negative predictive value that makes it easy to implement as a cervical cancer screening policy necessitating less screening rounds. High income countries are now implementing HC2 test in their national cervical cancer screening program. Since the acceptance of any screening test depends on the sensitivity of the test, the current study was carried out to evaluate the sensitivity of HC2 test reported from Low- and Middle-income countries (LMIC) which share major burden of cervical cancer globally and to establish if HC2 test could be used as a primary screening test in India.

HPV Vaccination in Women Treated for Cervical Intraepithelial Neoplasia: A Budget Impact Analysis.

Vaccines (Basel) 2021 Jul 22;9(8). Epub 2021 Jul 22.

Graduate School of Health Economics and Management (ALTEMS), Università Cattolica del Sacro Cuore, 00168 Rome, Italy.

Human Papillomavirus (HPV) is the most common sexually transmitted infection. Its progression is related to the development of malignant lesions, particularly cervical intraepithelial neoplasias (CINs). CINs correlate with a higher risk of premature births, and their excisional and ablative treatment further increases this risk in pregnant women. Read More

Cancers (Basel) 2021 Aug 21;13(16). Epub 2021 Aug 21.

Department of Behavioral Science, University of Kentucky Markey Cancer Center, Lexington, KY 40504, USA.

Disparities in human papillomavirus (HPV) vaccination exist between urban (metropolitan statistical areas (MSAs)) and rural (non-MSAs) regions. To address whether the HPV vaccine's impact differs by urbanicity, we examined trends in cervical intraepithelial neoplasia grades 2 or 3 and adenocarcinoma in situ (collectively, CIN2+) incidence in MSAs and non-MSAs among Tennessee Medicaid (TennCare)-enrolled women aged 18-39 years and among the subset screened for cervical cancer in Tennessee, United States. Using TennCare claims data, we identified annual age-group-specific (18-20, 21-24, 25-29, 30-34, and 35-39 years) CIN2+ incidence (2008-2018). Read More

Vaccination with Polyclonal Antibody Stimulator (PAS) Prevents Pancreatic Carcinogenesis in the KRAS Mouse Model.

Cancer Prev Res (Phila) 2021 Aug 24. Epub 2021 Aug 24.

Cancer Advances, Inc. Durham, North Carolina.

The incidence of pancreatic cancer is increasing significantly and will soon become the second leading cause of cancer-related deaths in the United States. We have previously shown that the gastrointestinal peptide gastrin, which is only expressed in the fetal pancreas and not in the adult pancreas, is activated during pancreatic carcinogenesis where it stimulates growth in an autocrine fashion. In this investigation, we used transgenic LSL-Kras; mice that develop precancerous pancreatic intraepithelial neoplasia (PanIN) lesions and pancreatic cancer over time. Read More
