We also thank all participants of the EnCoRe study and the health professionals in the three hospitals involved in the recruitment of participants of the study: Maastricht University Medical Center, VieCuri Medical Center, and Zuyderland Medical Center. We additionally thank the MEMIC center for data and information management for facilitating the logistic processes and data management of our study. Furthermore, we thank the research dieticians and research assistant who are responsible for patient inclusion and follow-up, performing home visits, as well as data collection and processing. Finally, we thank BEVITAL, Bergen, Norway for analysing hsCRP in the COLON and EnCoRe studies.

N2 - Background:Calcitriol, the active form of vitamin D, may inhibit colorectal cancer (CRC) progression, which has been mechanistically linked to an attenuation of a pro-inflammatory state. The present study investigated the associations between circulating 25 hydroxy vitamin D-3 (25(OH)D-3) levels and inflammatory markers (IL10, IL8, IL6, TNF alpha and hsCRP) in the 2 years following CRC diagnosis.Methods:Circulating 25(OH)D-3 levels and inflammatory markers were assessed at diagnosis, after 6, 12 and 24 months from 798 patients with sporadic CRC participating in two prospective cohort studies. Associations between 25(OH)D-3 levels and individual inflammatory markers as well as a summary inflammatory z-score were assessed at each time point by multiple linear regression analyses. To assess the association between 25(OH)D-3 and inflammatory markers over the course of 2 years, linear mixed model regression analyses were conducted.Results:Higher 25(OH)D-3 levels were associated with lower IL6 levels at diagnosis, at 6 months after diagnosis and over the course of 2 years (beta -0.06, 95% CI -0.08 to -0.04). In addition, 25(OH)D-3 levels were inversely associated with the summary inflammatory z-score at diagnosis and over the course of 2 years (beta -0.17, 95% CI -0.25 to -0.08). In addition, a significant inverse association between 25(OH)D-3 levels and IL10 was found over the course of 2 years. Intra-individual analyses showed an inverse association between 25(OH)D-3 and IL10, IL6 and TNF alpha. No statistically significant associations between 25(OH)D-3 and IL8 and hsCRP levels were observed.Conclusions:Serum 25(OH)D-3 levels were inversely associated with the summary inflammatory z-score and in particular with IL6 in the years following CRC diagnosis. This is of potential clinical relevance as IL6 has an important role in chronic inflammation and is also suggested to stimulate cancer progression. Further observational studies should investigate whether a possible 25(OH)D-3-associated reduction of inflammatory mediators influences treatment efficacy and CRC recurrence.
