Molecular Markers for early Detection of Cancer

The “MoMar“ project (molecular markers for early detection of cancer) deals with the development of molecular markers for the early detection of asbestos-related cancer of the lung and pleura and their validation in medical practice. Mesothelioma, a pleural cancer caused by asbestos, constitutes a major occupational health issue owing to its long latency and rising number of cases. Substantial research efforts are therefore still needed. The objective of the prevention study is to validate new molecular markers for early detection in high-risk collectives using a longitudinal design. The markers are determined non-invasively in blood or other body fluids. In addition, the method does not involve radiation exposure for the patient, in contrast to some imaging methods. The markers have the potential to complement radiological methods and may help to reduce radiation exposure. The high-risk collective comprises more than 2,700 workers formerly exposed to asbestos and exhibiting asbestosis, who were recruited from 2008 until 2017 and examined annually over a period of up to ten years.

In contrast to previous approaches, the prospective study of high-risk collectives enables biomarkers for early detection to be evaluated under substantially more realistic conditions for use in medical practice. So far, the proteins calretinin and mesothelin have been validated as tumor markers for the early detection of mesothelioma.

The combined markers are able to detect almost 50% of mesothelioma cases up to a year before classical diagnosis, with only 2% false-positive test results. In the future, the more than 180,000 aliquots of blood and plasma samples that have been stored in a biobank will serve as a valuable source for the validation of other new biomarkers.
