We envisage a future where a blood or urine home test kit is available so that people can be monitored for secondary breast cancer by providing test results to doctors without the burden of hospital or doctors visits.
An easy-to-use home test would enable earlier diagnosis, easier monitoring of the tumour response during treatment, and could provide peace of mind after treatment through routine checks for recurrence.
Secondary cancers are very hard to detect because tumours have to have grown to a certain size to be seen using current visual diagnosis methods (MRI, CT, X-ray scans and ultrasound), and they can arise in one or more places in the body (such as the lungs, bone, liver and brain) sometimes years after the primary breast tumour has been treated.
Blood tests do exist for secondary breast cancer, but a better test is needed that is more sensitive (can detect breast cancer sooner than current tests) and more accurate (does not give a positive result if the true result is negative and vice versa).
Researchers at the University of Westminster have looked at blood samples from over 3000 breast cancer patients that were collected in the DietCompLyf study, to look for new proteins that could act as biological markers of secondary spread and be useful in the design of new tests or to improve upon current diagnosis methods.
Using the latest ‘GlycoStation’ technology, they identified a protein called CDH-5 as a potential biomarker of secondary breast cancer.
As well as being presented at national cancer conferences, several scientific publications have been produced describing this work and can be found using the links below. Investigations into this protein and its potential to diagnose secondary disease before current tests allow, are ongoing.
