Cervical cancer screening - The challenges of complete pathways of care in low-income countries: Focus on Malawi.

Cervical cancer is the fourth most common cancer among women globally, with approximately 580,000 new diagnoses in 2018. Approximately, 90% of deaths from this disease occur in low- and middle-income countries, especially in areas of high HIV prevalence, and largely due to limited prevention and screening opportunities and scarce treatment options. In this overview, we describe the opportunities and challenges faced in many low- and middle-income countries in delivery of cervical cancer detection, treatment and complete pathways of care.

HPV infection and pre-term birth: a data-linkage study using Scottish Health Data.

We aimed to investigate whether infection with high-risk (HR) types of human papilloma virus (HPV) or HPV-associated cervical disease were associated with preterm birth (<37 weeks gestation). In a sub-group of younger women who were eligible for the HPV vaccine, we aimed to determine whether prior vaccination against the specific HPV-types, HPV-16 and -18 modified preterm birth risk. This was a data-linkage study, which linked HPV-associated viral and pathological information (from the Scottish HPV Archive) from women aged 16-45 years to routinely collected NHS maternity- and hospital-admission records from 1999-2015.

Development of an in-house ELISA to detect anti-HPV16-L1 antibodies in serum and dried blood spots.

Measuring anti-HPV antibody levels is important for surveillance of the immunological response to both natural infection and vaccination. Here, an ELISA test for measurement of HPV-16L1 antibodies was developed and validated in sera and dried blood spots. An in-house ELISA was developed for measuring anti-HPV-16L1 IgA and IgG levels.

Host chemokine signature as a biomarker for the detection of pre-cancerous cervical lesions.

Background: The ability to distinguish which hrHPV infections predispose to significant disease is ever more pressing as a result of the increasing move to hrHPV testing for primary cervical screening. A risk-stratifier or "triage" of infection should ideally be objective and suitable for automation given the scale of screening.

Results: CCL2, CCL3, CCL4, CXCL1, CXCL8 and CXCL12 emerged as the strongest, candidate biomarkers to detect underlying disease [cervical intraepithelial neoplasia grade 2 or worse (CIN2+)].

Eurogin roadmap 2017: Triage strategies for the management of HPV-positive women in cervical screening programs.

Cervical cancer screening will rely, increasingly, on HPV testing as a primary screen. The requirement for triage tests which can delineate clinically significant infection is thus prescient. In this EUROGIN 2017 roadmap, justification behind the most evidenced triages is outlined, as are challenges for implementation.
