Liquid biopsy using circulating tumor DNA (ctDNA) is being studied as a tool to detect minimal residual disease (MRD) after curative treatment. A Phase 2 trial is evaluating fruquintinib and tislelizumab specifically in patients with ctDNA-defined MRD after surgery, a precision medicine approach.

Cancer prevention is also under study. A Phase 2 trial is examining aspirin for prevention of colorectal cancer in patients with colorectal adenomas. A Phase 2 trial is testing a combination of vaccines for cancer prevention in Lynch syndrome, a hereditary predisposition to CRC.

Neoadjuvant regimens combining short-course radiotherapy with immunotherapyTreatments that use the body's immune system to fight cancer.Click for full explanation → including nivolumab or regorafenib are in Phase 2 for locally advanced rectal cancer.

Where the evidence stands

Adjuvant chemotherapyDrugs that kill rapidly dividing cells, including cancer cells.Click for full explanation → and metastatic regimens with bevacizumab or EGFR antibodies rest on strong Phase 3 evidence. Pembrolizumab for dMMR/MSI-H CRC has Phase 3 backing. ImmunotherapyTreatments that use the body's immune system to fight cancer.Click for full explanation → for non-MSI-H CRC remains an active problem, with Phase 2 and Phase 3 trials underway. BRAF-targeted combinations have Phase 3 support for a specific molecular subgroup. ctDNA-guided treatment, Lynch syndrome vaccines, and aspirin-based prevention are at Phase 2. AI-based colonoscopy assistance for polyp detection is an emerging research area.

What this means for people affected
