CRC Research Update

TRIAL DATA
Dual immunotherapy shows promise in mismatch repair proficient colon cancer
The phase 2 NEST trial tested neoadjuvant botensilimab plus balstilimab in patients with resectable colon cancer. The study examined safety, feasibility, and pathologic response before surgical resection. (Clinical Cancer Research)
SCREENING
CONFIRM trial examines race, ethnicity, and screening test use among Veterans
A study of 50,125 US Veteran participants in a randomized trial comparing colonoscopy to annual fecal immunochemical testing examined how race, ethnicity, and access to care factors relate to screening test use in a setting where financial barriers are reduced. (JNCI Cancer Spectrum)
LIVING WITH CRC
Incisional hernia impacts quality of life years after colorectal cancer surgery
The Rein4CeTo1 randomized trial evaluated quality of life, abdominal wall pain, and discomfort in patients 1 and 3 years after colorectal cancer surgery, using CT scans to diagnose incisional hernia. (Journal of Abdominal Wall Surgery)
LIVING WITH CRC
Case series documents bowel stenosis following immunotherapy in dMMR colorectal cancer
A case series documents bowel stenosis following immunotherapy in patients with mismatch repair deficient colorectal cancer. (Clinical Colorectal Cancer)

🧬 Biomarker Spotlight

Research by genetic subtype — KRAS, BRAF, MSI-H, HER2, and more

Kazakhstani pilot study profiles KRAS and BRAF mutations using NGS and ddPCR
Researchers used targeted next-generation sequencing and droplet digital PCR to characterize KRAS and BRAF mutations in metastatic colorectal cancer patients from Kazakhstan, where molecular epidemiological data remain limited. (Frontiers in Medicine)
MD Anderson explains DNA mismatch repair status for patients
An educational resource from MD Anderson helps patients understand mismatch repair deficiency and proficiency, key biomarkers that guide immunotherapy decisions. (UT MD Anderson Cancer Center)

Research continues to expand treatment options and improve quality of life for the colorectal cancer community.
