Project Details

Colorectal liver metastasis (CRCLM) is responsible for over 90% of colorectal cancer deaths. Resection of CRCLM is the only treatment offering potential long term survival. The outcome is limited by inadequate functional liver remnant and tumour recurrence following surgery. Liver regeneration restores liver function however the molecular mechanisms in liver regeneration also stimulate tumour recurrence.

Our studies show that renin angiotensin system (RAS) inhibition enhanced liver regeneration and significantly inhibited tumour progression. Reduced local and systemic inflammation upon treatment suggest it to be a main mechanism for these results.
