New cancer test welcomed

OUR Don’t Fear The Smear campaign has been very much focused on cervical cancer so far, but we welcome news about ovarian cancer testing this week, another women only disease.

Researchers from Queen’s University Belfast have developed a test that may be able to detect ovarian cancer up to two years earlier than current approaches.

The researchers discovered that the presence of four proteins together, known as a biomarker panel, indicates the likelihood of Epithelial Ovarian Cancer (EOC), a type of ovarian cancer. Using these biomarkers the researchers then developed a screening test that initial studies suggest may be able to detect ovarian cancer up to two years before current detection tests.

The research was carried out in partnership with the University of New South Wales Australia, University of Milan, University of Manchester and University College London. The study, published in the high-impact journal Nature, involved the analysis of blood samples from 80 individuals across a seven-year period. Dr Bobby Graham, from the School of Biological Sciences at Queen’s University Belfast and lead author of the study, said: “The algorithm designed will screen the blood sample and flag any abnormal levels of the proteins associated with the cancer. The screening test identifies ovarian cancer up to two years before the current tests allow.”

Most ovarian cancers are epithelial ovarian cancers, which is a cancer that forms in the tissue covering the ovary. In females in the UK, ovarian cancer is the sixth most common cancer and in 2016, there were 4227 deaths. However, if diagnosed early, at stage one, there is a 90 per chance of five-year survival, compared to 22 per cent if diagnosed at a stage three or four.

Dr Graham added: “The results of this study are encouraging, however, we now want to focus on testing it in a wider sample set so that we can use the data to advocate for an ovarian cancer screening programme.”

Dr Rachel Shaw, from Cancer Research UK, added: “Around half of ovarian cancer cases are picked up at a late stage, when treatment is less likely to be successful. So developing simple tests like these that could help detect the disease sooner is essential. “It’s really exciting to see these encouraging results for this type of ovarian cancer.”

The project was jointly funded by the Eve Appeal charity and Cancer Research UK.
