Cervical cancer in women with MS

Summary

Relapsing multiple sclerosis (MS) can be treated with numerous disease-modifying therapies (DMTs) that can slow both relapse rates and disease progression. All of these treatments work by modulating the immune system, but in different ways. Treatment in MS is often started at a young age and continued for decades or even life-long. This long-term action on the immune response may predispose individuals to a higher risk of infections.  

Human Papillomavirus (HPV) is the most common sexually transmitted virus in the world and, in the event of persistent infection to the cervix, can result in the development of abnormal cells and cervical cancer. This process can take decades to develop.  

This study aims to determine if exposure to DMTs in women with MS increases the risk of HPV infection, cervical cell abnormalities, and cervical cancer. The team will achieve this by linking MS disease information from the MSBase Registry with the National Cervical Cancer Registry and the Australian Immunization Registry. The results have the potential to change the way that women with MS are screened for cervical cancers and to provide evidence that HPV-vaccination should be provided to all women with MS.
