Newly published results from ASX-listed diagnostics trailblazer Proteomics International Laboratories have unveiled stunning new clinical findings for its simple PromarkerEso oesophageal cancer blood test, opening the way for the innovative blood test to be commercially released. The test’s accuracy was demonstrated in a 259-person study across three patient groups in Australia and the United States. The results were posted overnight in the peer-reviewed journal Proteomes, providing a major academic rubber stamp for the technology. The new findings showed that the test could detect a whopping 91.4 out of 100 patients with the heartburn-related cancer and correctly identify 98.9 per cent of people without it, offering a powerful, non-invasive alternative to costly and uncomfortable endoscopies. Based on the results, PromarkerEso outperforms many tests currently used for screening other types of cancers. For context, the widely used Prostate-Specific Antigen blood test used to diagnose prostate cancer has an Area Under Curve (AUC) measurement of just 0.68, while PromarkerEso hit an exceptional AUC of 0.98. An AUC greater than 0.7 is considered to offer acceptable discrimination, while above 0.9 is considered outstanding.
