Exercise before liver surgery to lower colorectal cancer recurrence
Surgery triggered immune response and liver metastases
Exercise before liver surgery aims to calm harmful immune responses and reduce the chance colorectal cancer comes back in the liver for people with liver metastases.

What this research studies
This project looks at how pre-operative exercise changes immune cells in the liver and tumor environment to make the body less likely to let cancer return after surgery. Researchers will analyze resident liver macrophages (Kupffer cells) and neutrophil-like suppressor cells, studying metabolic shifts such as itaconate-related reprogramming and the formation of neutrophil extracellular traps (NETs). They will use tissue analyses including single-cell RNA sequencing and experimental models alongside surgical samples to link immune changes with recurrence risk. The aim is to identify how exercise creates an anti-inflammatory environment that could lower hepatic recurrence after colorectal cancer surgery.
Who could benefit from this research
Good fit: People with colorectal cancer who have or are planned to have liver metastasis surgery would be the primary candidates for related interventions or future trials.
Not a fit: People without colorectal cancer, those not undergoing liver surgery, or individuals unable to do pre-operative exercise are unlikely to benefit from this work.
Why it matters
Potential benefit: If successful, this work could lower the risk of liver recurrence after surgery and improve long-term outcomes for people with colorectal cancer that has spread to the liver.
How similar studies have performed: Pre-operative exercise has improved recovery and reduced inflammation in other major abdominal surgeries, and early data suggest it can blunt surgery-induced liver inflammation, but using it specifically to prevent liver metastasis recurrence is a newer application.
