PURPOSE Tumor infiltrating T lymphocytes in colorectal cancer (CRC) have prognostic impact, but the role of natural killer (NK) cells in CRC tissue is unclear. The contribution of intratumoral cytokines and chemokines in shaping the composition of the inflammatory lymphocytic infiltrate is also unclear. EXPERIMENTAL DESIGN In this study, localization and(More)
OBJECTIVE To analyze intratumoral heterogeneity of immune cells and the resulting impact of heterogeneity on the level of individual patient prediction. STUDY DESIGN Using whole slide imaging by virtual microscopy, we present the first spatial quantitative study of immune cells in a set of colorectal cancer primary tumors. We generated "tumor maps" based(More)
Analysis of tumor-infiltrating lymphocytes (TIL) in primary human colorectal cancer (CRC) by in situ immunohistochemical staining supports the hypothesis that the adaptive immune response influences the course of human CRC. Specifically, high densities of TILs in the primary tumor are associated with good prognosis independent of other prognostic markers.(More)
BACKGROUND Determining the correct number of positive immune cells in immunohistological sections of colorectal cancer and other tumor entities is emerging as an important clinical predictor and therapy selector for an individual patient. This task is usually obstructed by cell conglomerates of various sizes. We here show that at least in colorectal cancer(More)
