Abstract

Intratumor heterogeneity of tumor clones and an immunosuppressive microenvironment in cancer ecosystems contribute to inherent difficulties for tumor treatment. Recently, chimeric antigen receptor (CAR) T-cell therapy has been successfully applied in the treatment of B-cell malignancies, underscoring its great potential in antitumor therapy. However, functional challenges of CAR-T cell therapy, especially in solid tumors, remain. Here, we describe cancer-immunity phenotypes from a clonal-stromal-immune perspective and elucidate mechanisms of T-cell exhaustion that contribute to tumor immune evasion. Then we assess the functional challenges of CAR-T cell therapy, including cell trafficking and infiltration, targeted-recognition and killing of tumor cells, T-cell proliferation and persistence, immunosuppressive microenvironment and self-control regulation. Finally, we delineate tumor precision informatics and advancements in engineered CAR-T cells to counteract inherent challenges of the CAR-T cell therapy, either alone or in combination with traditional therapeutics, and highlight the therapeutic potential of this approach in future tumor precision treatment.

  • Because antigen targets used for anti-CRC CAR T-cell therapy are often expressed in normal cells, accurate recognition of tumor-associated antigens (TAAs) is difficult, resulting in a therapy with low specificity.

    “given that the antigen targets used for anti-CRC CAR T-cell therapy are often expressed in normal cells, the accurate recognition of tumor-associated antigens (TAAs) is rather difficult, resulting in a therapy with low specificity [140]”
  • Reconstructed and expanded CAR-T cells are exposed to the patient's tumor microenvironment, thereby inducing the senescent phenotype of CAR-T.

    “The reconstructed and expanded CAR-T cells are exposed to the patient's tumor microenvironment, thereby inducing the senescent phenotype of CAR-T [122, 123].”

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.
