Article Abstract

Although immune checkpoint inhibitor (ICI) therapy is currently the standard of care in microsatellite-unstable (MSI) metastatic colorectal cancer (CRC), ICI therapy, alone or in combination with other therapies, is not a treatment approach in microsatellite-stable (MSS) CRC, which is present in 95% of patients. In this review, we focus on metabolic singularities-at the transcriptomic (either bulk or single cell), proteomic, and post-translational modification levels-that induce immunosuppression in cancer and specifically in MSS CRC. First, we evaluate the current efficacy of ICIs in limited and metastatic disease in MSS CRC. Second, we discuss the latest findings on the potential biomarkers for evaluating ICI efficacy in MSS CRC using strict REMARK criteria. Third, we review the current evidence on metabolic patterns in CRC tumors and immune cell metabolism to advance our understanding of metabolic crosstalk and to pave the way for the development of combination strategies to enhance ICI efficacy.

Immune checkpoint inhibitors (ICIs) can re-active the immune response and induce a complete response in mismatch repair-deficient and microsatellite instability-high (dMMR/MSI-H) colorectal cancer (CRC). However, most CRCs exhibit proficient mismatch repair and microsatellite stable (pMMR/MSS) phenotypes with limited immunotherapy response because of sparse intratumoral CD8 T-lymphocyte infiltration. Cellular senescence has been reported to involve immune cell infiltration through a senescence-associated secretory phenotype (SASP).

Purpose: Management of colorectal cancer (CRC) is determined by the stage of the disease and molecular features, such as microsatellite instability (MSI). MSI-high/deficient mismatch repair (MSI-H/dMMR) tumors respond better to immunotherapy but poorly to 5-FU-based treatments. With increasing use of neoadjuvant chemotherapy there is interest in developing non-invasive, radiomics models based on preoperative contrast-enhanced CT scans to predict MSI status and support personalized therapy.

The RTK-RAS signaling cascade is a central axis in colorectal cancer (CRC) pathogenesis, governing cellular proliferation, survival, and therapeutic resistance. Somatic alterations in key pathway genes-including KRAS, NRAS, BRAF, and EGFR-are pivotal to clinical decision-making in precision oncology. However, the integration of these genomic events with clinical and demographic data remains hindered by fragmented resources and a lack of accessible analytical frameworks.

The BRAF inhibitor encorafenib and anti-epidermal growth factor receptor (EGFR) antibody cetuximab modestly improve survival for patients with microsatellite stable (MSS) BRAF metastatic colorectal cancer (mCRC), characterized by higher immune activation than MSS BRAF colorectal cancer (CRC). In this phase 1/2 study (NCT04017650) of 26 participants with MSS BRAF mCRC who received encorafenib, cetuximab, and anti-PD-1 antibody nivolumab, we report an overall response rate of 50% (95% confidence interval [CI] 29-71) and median progression-free survival of 7.4 months (95% CI, 5.

Immune checkpoint inhibitors have made remarkable impacts in treating various cancers, including colorectal cancer (CRC). However, CRC still remains a leading cause of cancer-related deaths. While microsatellite instability (MSI) CRC has shown positive responses to anti-PD-1 therapy, this subgroup represents a minority of all CRC patients.
