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

Comparing and contrasting clinical consensus and guidelines for anal intraepithelial neoplasia in different geographical regions.

Updates Surg 2021 Sep 4. Epub 2021 Sep 4.

Chelsea and Westminster Hospitals NHS Foundation Trust, London, UK.

Anal Squamous Cell Carcinoma (ASCC) is an uncommon cancer with a recognised precursor Anal Intraepithelial Neoplasia (AIN). Although there are consistent evidence-based guidelines for the management of ASCC, historically this has not been the case for AIN and as a result there have been geographical variations in the recommendations for the treatment of AIN. More recently there have been updates in the literature to the recommendations for the management of AIN. Read More

Human Papillomavirus Related Neoplasia of the Ocular Adnexa.

Viruses 2021 Aug 2;13(8). Epub 2021 Aug 2.

Department of Pathology, Copenhagen University Hospital Rigshospitalet, DK-2100 Copenhagen, Denmark.

Human papillomaviruses (HPV) are a large group of DNA viruses that infect the basal cells of the stratified epithelium at different anatomic locations. In the ocular adnexal region, the mucosa of the conjunctiva and the lacrimal drainage system, as well as the eyelid skin, are potential locations for HPV-related neoplasia. The role of HPV in squamous cell neoplasia of the ocular adnexa has been debated for several decades. Read More

Department of Medical Technology, Faculty of Health Sciences, Kyorin University, 5-4-1 Shimorenjaku, Mitaka-shi, Tokyo 181-8621, Japan.

Many genotypes of human papillomaviruses (HPVs) may lead to morphological changes in cells, resulting in various atypical cells, such as multinucleated cells (MNCs) and koilocytes, in the cervix. However, the relationships between the profiles of HPV genotypes and MNCs are not exactly known. Thus, this study comprehensively profiles the HPV genotypes in MNCs using a microdissection method.

Center for Clinical Research and Innovation (CCRI), Shenzhen Hospital, Southern Medical University, The Third School of Clinical Medicine, Southern Medical University, Shenzhen, China.

Persistent infection with human papillomavirus (HPV) and immune surveillance failure may be the initiating factors for the carcinogenesis of cervical squamous cell carcinoma (CSCC). HPV infection might affect the innate immune pathway of cervical epithelial cells that constitute the "microenvironment" for tumor cells. Programmed death-ligand 1 (PD-L1) has been reported to be an immunosuppressor that helps cancer cells escape the actions of T cells. Read More

Gynecology and Obstetrics Department, Women's and Children's University Hospital, Avda. Marítima del Sur s/n, Las Palmas de Gran Canaria 35016, Spain. Electronic address:

Objective: To compare and evaluate the results and suitability of two different approaches to the treatment of post-conization International Federation of Gynaecology and Obstetrics (FIGO) stage IA1 cervical carcinoma: a more radical approach, directly scheduling a second surgery versus a more conservative one, which consists of performing a cotest (PAP plus HPV-test) in a follow-up visit and deciding whether to apply a second surgery on the basis of the results.

Study Design: Retrospective descriptive study including 144 cases of stage IA1 cervical carcinoma diagnosed after a loop electrosurgical excisional procedure (conization), between 1987 and 2019 in the Mother-and-Child University Hospital of Gran Canaria (Spain). Selected patients were split into two groups for analysis: patients directly undergoing a second surgical intervention (hysterectomy or re-conization) after diagnosis and patients who were followed-up before making a decision whether to schedule a second surgery or continue to follow-up.

Sci Rep 2021 Aug 10;11(1):16244. Epub 2021 Aug 10.

Department of Pathology, Tri-Service General Hospital, Taipei, Taiwan.

Every year cervical cancer affects more than 300,000 people, and on average one woman is diagnosed with cervical cancer every minute. Early diagnosis and classification of cervical lesions greatly boosts up the chance of successful treatments of patients, and automated diagnosis and classification of cervical lesions from Papanicolaou (Pap) smear images have become highly demanded. To the authors' best knowledge, this is the first study of fully automated cervical lesions analysis on whole slide images (WSIs) of conventional Pap smear samples. Read More

High-risk human papillomavirus (HPV) detection in formalin-fixed paraffin-embedded cervical tissues: performances of Aptima HPV assay and Beckton Dickinson (BD) Onclarity assay.

J Clin Pathol 2021 Aug 10. Epub 2021 Aug 10.

Department of Pathology, Royal Group of Hospitals and Dental Hospital Health and Social Services Trust, Belfast, UK.

Aim: There are many scenarios where high-risk human papillomavirus (HPV) detection in formalin-fixed paraffin-embedded (FFPE) specimens is important. However, there is no Food and Drug Administration (FDA)-approved and clinically validated technique for detecting high-risk HPV in FFPE tissues. In this study, we evaluated two commercially available HPV assays which are FDA-approved for use on cytology specimens, the Aptima HPV assay and the Beckton Dickinson (BD) Onclarity assay, to detect high-risk HPV in FFPE tissues of cervical high-grade squamous intraepithelial lesion (HSIL) and squamous cell carcinoma (SCC).
