Abstract

Treatment of metastatic colorectal cancer is based upon the assumption that metastases are homogeneous within a patient. We quantified immune cell types of 603 whole-slide metastases and primary colorectal tumors from 222 patients. Primary lesions, and synchronous and metachronous metastases, had a heterogeneous immune infiltrate and mutational diversity. Small metastases had frequently a low Immunoscore and T and B cell score, while a high Immunoscore was associated with a lower number of metastases. Anti-epidermal growth factor receptor treatment modified immune gene expression and significantly increased T cell densities in the metastasis core. The predictive accuracy of the Immunoscore from a single biopsy was superior to the one of programmed cell death ligand 1 (PD-L1). The immune phenotype of the least-infiltrated metastasis had a stronger association with patient outcome than other metastases.

  • Assessing the densities of T and B cells within CRC tumors offers higher accuracy compared to evaluating PD-L1 expression alone in predicting the efficacy of immunotherapy.

    “Recent findings suggest that assessing the densities of T and B cells within CRC tumors offers higher accuracy compared to evaluating PD-L1 expression alone in predicting the efficacy of immunotherapy.”
  • PD-L1 expression can vary heterogeneously within different regions of a tumor, while metastatic CRC lesions may exhibit varying immunoscores.

    “This is because PD-L1 expression can vary heterogeneously within different regions of a tumor, while metastatic CRC lesions may exhibit varying immunoscores [163,164].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
