How long can you live with metastatic cancer of the bowels in the liver?

It depends...: Hard to answer in this setting. Treatments are improving. For colon cancer metastatic (spread) to liver options include: a) surgery or other "local" liver treatments (rfa, cryotherapy, etc) if confined b) chemotherapy for systemic (non-local) treatment c) palliative / symptom control without active therapy colon cancer with only one or few (oligo) metastatic disease to the liver can even be cured.

It depends: Isolated colorectal metastases to the liver can sometimes be surgically removed. If this is the case, around 40% of patients can live beyond 5 years. While historical figures have the average patient living 12 months, realize that this was with older drugs... There have been a lot of recent improvements so talk to your medical oncologist for more information!
