Biomarker Research in EPIC
Over the past decades, cancer research has used biochemical markers with the aim of better defining exposure, improving early detection, and refining susceptibility, to better understand the etiology of the disease, and to improve its treatment.
The large and diverse collection of the EPIC biobank, and the optimal long-term storage of its biological specimens (liquid nitrogen), allows the measurements of pre-diagnostic biomarkers of exposure, recovery, and prediction (from serum, plasma, and red blood cells), and provides the opportunity to study genetic susceptibility (by extracting DNA from buffy coats) to perform studies at the forefront of research. The long follow-up of the EPIC cohort is key for the identification of potential markers of early detection.
More than 80 manuscripts have been published so far in high-impact-factor journals on biomarker-based research in EPIC. Many of these were breakthrough studies and opened new avenues of research on cancer etiology. Major results include associations of endogenous hormones with breast cancer risk in pre- and post-menopausal women (overall and by receptor status), of circulating plasma phospholipid fatty acid concentrations (especially oleic acid, α-linolenic acid, and di-homo-γ-linolenic acid) and gastric adenocarcinomas, the reduction in colorectal cancer risk with increasing circulating vitamin D concentrations, of lung cancer risk with increasing vitamin B6 and methionine concentrations, and of colon cancer risk with increasing serum HDL.
In addition to publications based only on its own data, EPIC is substantially contributing to large, international collaborative studies and consortia exploring biomarker-based research on cancer or intermediate end-points: Endogenous Hormones and Breast Cancer Collaborative Group, InterAct, and EPIC-Heart.
