False Negative Results in Cervical Cancer Screening-Risks, Reasons and Implications for Clinical Practice and Public Health.

Diagnostics (Basel) 2022 Jun 20;12(6). Epub 2022 Jun 20.

Department of Cancer Prevention, The Maria Sklodowska-Curie National Research Institute of Oncology, Roentgen Street 5, 02-781 Warsaw, Poland.

False negative (FN) results in cervical cancer (CC) screening pose serious risks to women. We present a comprehensive literature review on the risks and reasons of obtaining the FN results of primary CC screening tests and triage methods and discuss their clinical and public health impact and implications. Misinterpretation or true lack of abnormalities on a slide are the reasons of FN results in cytology and p16/Ki-67 dual-staining. Read More

Using the Consolidated Framework for Implementation Research to Inform the Design of the Mobile Inspección Visual con Ácido Acético System: Mixed Methods Case Study.

JMIR Form Res 2022 Jun 23;6(6):e32577. Epub 2022 Jun 23.

Duke University School of Medicine, Durham, NC, United States.

Background: There is growing evidence supporting the use of mobile health (mHealth) interventions in low- and middle-income countries to address resource limitations in the delivery of health information and services to vulnerable populations. In parallel, there is an increasing emphasis on the use of implementation science tools and frameworks for the early identification of implementation barriers and to improve the acceptability, appropriateness, and adoption of mHealth interventions in resource-limited settings. However, there are limited examples of the application of implementation science tools and frameworks to the formative phase of mHealth design for resource-limited settings despite the potential benefits of this work for enhancing subsequent implementation, scale-up, and sustainability.

N Z Med J 2022 Feb 25;135(1550):146-156. Epub 2022 Feb 25.

FRANZCOG, Gynaecologic Oncologist at Christchurch Women's Hospital.

Aims: We investigated whether patient choice of follow-up type improves health-related quality of life (HrQOL) and follow-up attendance in women who have undergone large loop excision of the transformation zone (LLETZ) for cervical intraepithelial neoplasia grade 2 to 3 (CIN 2-3).

Methods: A three-armed randomised controlled trial including women with newly diagnosed CIN 2-3 post-LLETZ treatment was performed. Consenting women were randomised (1:1:1) to either: (a) colposcopy review at the hospital, (b) follow-up with high-risk human papilloma virus (HrHPV) and smear test in the community or (c) a choice of the aforementioned follow-up options, six months post-treatment.

The gray zone squamous lesions: ASC-US / ASC-H.

Cytojournal 2022 30;19:30. Epub 2022 Apr 30.

Department of Pathology, Government Medical College, Nagpur, Maharashtra, India.

The unequivocal and easily recognizable entities of LSIL and HSIL pose no diagnostic problems for a trained eye. However, when the defining morphologic features are either qualitatively or quantitatively insufficient, it is then that the borderline category of "Atypical Squamous cells" (ASC) may have to be used. Scant and suboptimal preparations (mainly in conventional smears) are the common causes that hinder confident decision-making. Read More

Natural Language Processing to Identify Abnormal Breast, Lung, and Cervical Cancer Screening Test Results from Unstructured Reports to Support Timely Follow-up.

Stud Health Technol Inform 2022 Jun;290:433-437

Department of General Internal Medicine, Brigham and Women's Hospital, Boston, MA, United States.

Cancer screening and timely follow-up of abnormal results can reduce mortality. One barrier to follow-up is the failure to identify abnormal results. While EHRs have coded results for certain tests, cancer screening results are often stored in free-text reports, which limit capabilities for automated decision support. Read More
