CRC Research Update

• ▪ SCREENING

  AHN researchers help develop blood test that detects colorectal cancer and high-risk polyps

  Researchers at Allegheny Health Network contributed to development of a blood-based screening test capable of detecting both colorectal cancer and high-risk polyps. (Beaver County Radio)

• ◇ RESEARCH

  Targeting peripheral serotonin receptor enhances antitumor immunity in colorectal cancer

  Researchers developed IHCH-8110, a non-brain-penetrant 5-HT2AR agonist that activates serotonin receptors on enteric glial cells to promote CD8+ T cell recruitment and suppress colorectal cancer growth without psychedelic effects. (Cell)

• ◇ RESEARCH

  TAP1 deficiency creates new immunotherapy targets in colorectal cancer

  Loss of TAP1, an immune escape mechanism found in 26% of colorectal cancers, generates alternative T cell epitopes that may be exploitable for immunotherapy; researchers identified CD8 T cells from patient tumors that can target TAP1-deficient cancer cells. (Molecular Therapy Oncology)

• ♥ LIVING WITH CRC

  Inflammation may limit muscle-building benefits of high-protein nutrition during treatment

  A post-hoc analysis of the PRIMe trial found that baseline systemic inflammation influenced the effectiveness of high-protein nutritional support to increase lean soft tissue in patients with stage II-IV colorectal cancer. (American Journal of Clinical Nutrition)

Research continues to advance our understanding of colorectal cancer screening, immunotherapy targets, and supportive care during treatment.
