A paper-based HPV E7 oncoprotein assay for cervical precancer detection at the point of care.

Cervical cancer, while preventable through screening and treatment of cervical precancer, remains a global challenge with a disproportionately high burden of disease in resource-limited settings, especially in low- and middle-income countries (LMICs). Lack of affordable, easy-to-use screening and diagnostic tests contributes to this disparity. Most commercially available tests are not appropriate for use in LMICs due to resource constraints.

Development and Evaluation of an Automated Multimodal Mobile Detection of Oral Cancer (mDOC) Imaging System to Aid in Risk-based Management of Oral Mucosal Lesions.

Oral cancer is a major global health problem. It is commonly diagnosed at an advanced stage although often preceded by clinically visible oral mucosal lesions, termed oral potentially malignant disorders associated with an increased risk for oral cancer development. There is an unmet clinical need for effective screening tools to assist front-line healthcare providers to determine which patients should be referred to an oral cancer specialist for evaluation.

A High-Resolution Microendoscope Improves Esophageal Cancer Screening and Surveillance: Implications for Underserved Global Settings Based on an International Randomized Controlled Trial.

Background & Aims: Lugol's chromoendoscopy (LCE)-based detection of esophageal squamous cell neoplasia (ESCN) is limited by low specificity. High-resolution microendoscopy (HRME) was shown to improve specificity and reduce unnecessary biopsies when used by academic endoscopists. In this international randomized controlled trial, we determined the clinical impact, efficiency, and performance of HRME in true global health contexts with a range of providers.

Scaling cervical cancer screening in Mozambique: analysis of loop electrosurgical excision procedure (LEEP) specimens.

Objectives: As cervical cancer screening programs are implemented and expanded, an increasing number of women require loop electrosurgical excision procedure (LEEP) for treatment of pre-invasive cervical disease. Our objective was to describe the pathological results of LEEP specimens performed as part of the MULHER study and identify factors associated with positive LEEP margins.

Methods: The MULHER study enrolled 9014 women who underwent HPV testing followed by visual assessment for treatment (VAT) using visual inspection with acetic acid (VIA) and thermal ablation for those with positive results.

Optical imaging for screening and early cancer diagnosis in low-resource settings.

Low-cost optical imaging technologies have the potential to reduce inequalities in healthcare by improving the detection of pre-cancer or early cancer and enabling more effective and less invasive treatment. In this Review, we summarise technologies for in vivo widefield, multi-spectral, endoscopic, and high-resolution optical imaging that could offer affordable approaches to improve cancer screening and early detection at the point-of-care. Additionally, we discuss approaches to slide-free microscopy, including confocal imaging, lightsheet microscopy, and phase modulation techniques that can reduce the infrastructure and expertise needed for definitive cancer diagnosis.
