Significant strides have been made in decreasing cervical cancer rates around the world. In fact, Member States of the World Health Organization (WHO) have adopted a number of decisions to advance global public health, including specific goals calling for the elimination of cervical cancer.

Still, this preventable disease is far too common. Cervical cancer is missed and diagnosis is often delayed. This is due to a number of factors. Too many women are not being screened regularly or go too long between well-woman exams. Conventional tests used for screening and management yield potentially discrepant results, which require waiting for a re-test or further procedures that may cause unnecessary worry or delayed diagnosis.

Roche has studied the science of Human Papillomavirus (HPV), the infection that is associated with over 99% of cervical cancers¹, to develop advanced solutions to find disease early, and prevent invasive cervical cancer from developing. Triage and diagnosis of pre-cancers using biomarker technology simplifies testing and ensures laboratories and doctors get clear, actionable information. Based on more definitive risk assessment, women can be given the right guidance and care at the right time, protecting them from the potential harms or over- or under-treatment.

There has been good progress at protecting women from developing cervical cancer but we can all do better. Roche is dedicated to investing in advancements that will significantly improve prevention strategies and support global efforts to eradicate this disease. Our approach is always based on the strength of clinical evidence and insights to challenge the status quo. We are committed to providing effective and simple solutions that give doctors and labs the answers they need and women the protection and care they deserve.

With vaccination, regular screening and treatment, cervical cancer is highly preventable, yet over 600,000 women developed the disease in 2020 and over 340,000 died from it.⁵ Recognised as one of the top causes of death for women around the world, most cases occur in countries that have not yet established systematic, organised HPV screening.⁶ However, even in the US, where access to screening and women's health care is widely available, there is still too high a prevalence of cervical disease. The American Cancer Society reports 14,480 new cases of invasive cervical cancer will be diagnosed and approximately 4,290 women will die from the disease in 2021.⁷

Need to move past the status quo

Over the past several decades, screening strategies based on Pap cytology have saved millions of lives, but there is significant need for improvement. Abnormal Pap test results are common and women often endure repeat testing and waiting before they learn if cervical disease is present.

Potentially discrepant screening results when HPV and Pap cytology are used together can sometimes lead to uncertainties and leave labs and healthcare providers without the evidence they need to make confident next step decisions. Roche is leading the next evolution in cervical cancer screening, triage and diagnosis to address these still unmet needs.

Advanced biomarker - based testing for triage fills in the gaps left by Pap cytology and when Pap and HPV testing are used together by identifying clear evidence of cell transformation to precancer or cancer. Now available in the US and worldwide, CINtec^® PLUS Cytology is the first FDA-approved triage test that uses objective biomarker technology to remove the uncertainty for women identified as at-risk by a positive HPV result.

CINtec^® PLUS Cytology uses an immunocytochemical dual-stain, to look for the simultaneous presence within a single cell of two biomarkers – p16 and Ki-67 – in a cervical cytology sample. The co-expression of biomarkers p16 and Ki-67 indicates an abnormality that provides definitive information to help differentiate which HPV positive women may benefit most from immediate intervention. Women who test dual-stain negative for p16 and Ki-67 are very unlikely to have a transforming infection, and can be given more time to allow their body to clear the virus, without intervention.

The CINtec^® PLUS Cytology test is performed on the same sample collected for a Pap or HPV test, eliminating the need for additional office visits or waiting time.

As women positive for HPV are at greater risk for having or developing pre-cancerous cervical lesions, labs need a test they can rely on to find pre-cancerous lesions so they can be diagnosed and treated before they develop into invasive cancers. CINtec^® Histology is an immunohistochemistry assay that detects the p16 biomarker in cervical biopsies. This advanced test plays a key role when a cervical biopsy is taken as a result of an abnormal cervical screening result by providing additional objective information to diagnostic interpretation that helps to detect more cervical lesions due to transforming HPV infections. Clear objective evidence enables pathologists to conclusively diagnose cervical precancer, and improves reproducibility when interpreting equivocal findings, so they can deliver definitive results that help clinicians make informed decisions and ensure the right women receive the best possible treatment for this highly preventable disease.
