Fewer than 50% of metastatic deficient mismatch repair (dMMR) colorectal cancer (CRC) patients respond to immune checkpoint inhibition (ICI). Identifying and expanding this patient population remains a pressing clinical need. Here, we report that an interferon-high immunophenotype locally enriched in cytotoxic lymphocytes and antigen-presenting macrophages is required for response.

Multiple strategies are continuously being explored to expand the drug target repertoire in solid tumors. We devised a novel computational workflow for transcriptome-wide gene expression outlier analysis that allows the systematic identification of both overexpression and underexpression events in cancer cells. Here, it was applied to expression values obtained through RNA sequencing in 226 colorectal cancer (CRC) cell lines that were also characterized by whole-exome sequencing and microarray-based DNA methylation profiling.

Article Synopsis
  • The study investigates the potential of targeting DNA damage response (DDR) as a therapeutic strategy for colorectal cancer, especially in cases where conventional treatments fail.
  • Researchers tested 112 cell models and discovered that about 30% of colorectal cancers exhibit sensitivity to at least one DDR inhibitor, particularly focusing on ATR inhibitors (ATRi).
  • Identified biomarkers, such as reduced phospho-RPA32 levels and increased RAD51 formation, could help determine which colorectal cancers are likely to respond to ATR inhibitors, offering hope for patients with resistant tumors.

Colorectal cancer (CRC) is one of the most common human malignancies accounting for approximately 10 % of worldwide cancer incidence and mortality. While early-stage CRC is mainly a preventable and curable disease, metastatic colorectal cancer (mCRC) remains an unmet clinical need. Moreover, about 25 % of CRC cases are diagnosed only at the metastatic stage.
