Spatial petterns and prognostic relevance of CD1a+ immature and CD208+ mature dendritic cells in colorectal cancer from non-tumor adjacent mucosa to liver metastases

Original language description

The prognostic role of dendritic cells (DCs) in colorectal cancer (CRC) and paired liver metastases (LM) remains unclear, particularly regarding the dynamics of immature CD1a+ and mature CD208+ subsets across anatomical compartments and synchronous versus metachronous disease. Patients and methods: This retrospective cohort included patients undergoing resection of primary CRC (pCRC) and synchronous LM (N = 55) or metachronous LM (N = 44). Immunohistochemical staining for CD1a and CD208 was performed on non-tumor adjacent mucosa (NAM), as well as tumor center (TC), inner margin (IM), outer margin (OM), and peritumoral zone (PT) of both pCRC and LM. Cell densities were quantified on whole-slide images using QuPath software and correlated with overall survival (OS). Results: CD1a+ DCs were nearly absent in NAM but enriched in pCRC TC, whereas CD208+ DCs predominated in lymphoid aggregates associated with NAM and peripheral compartments of pCRC and LM. CD1a+ cells followed a TC/IM > OM/PT gradient, while CD208+ cells showed the opposite, consistent with a recruitment-maturation axis. In synchronous cases, CD1a+ densities were higher in pCRC than LM, supporting the role of the primary tumor as a "monocyte reservoir." Survival analysis revealed that high CD208+ density in TC of synchronous LM (hazard ratio (HR) = 0.47; p = 0.033) and high CD1a+ density in TC of metachronous LM (HR = 0.44; p = 0.050) were both associated with reduced mortality risk. Conclusion: This study provides the first detailed mapping of CD1a+ and CD208+ DCs across NAM, pCRC and paired LM, indicating that their prognostic impact is determined not only by absolute numbers but, more importantly, by compartmental distribution and the temporal pattern of metastasis.
