Here's why cancer spreads to the liver

Postby juliej » Thu Mar 07, 2019 7:37 pm

Ever been curious why CRC spreads to the liver?

A new study, published today in Nature, shows how a chain reaction involving hepatocytes creates the "soil" needed for cancer cells to "seed."

The seed-and-soil theory has been known for awhile, but they didn't know hepatocytes were the major originators of this process. Hepatocytes, which are the chief functional cells of the liver, sense inflammation and respond in a way that cancer uses to help it spread. That means potentially the process could be stopped by using antibodies that block IL-6 (interleukin 6), the "trigger" that drives the chain reaction.

It still doesn't explain why it doesn't go to the liver in some people and just heads straight for the lungs instead. Maybe there's some "pro-metastatic" process involved there too. However, I think this could lead to new therapies, which is always good! :D

Great info JJ
thanks for posting !!!!

Just me I know ... BUTT the whole IL-6 thing with it being a PROmoter of inflammatory process and yet
an anti-inflammatory moiety involved in regeneration and renewal etc.
= Yin / Yang BALANCE

I did note though, that the articles really don't address the lymphatic flow which would bypass the abdominal vascularity via the thoracic duct ...
ergo why a lotta rectosigmoids met TO the chest as opposed to the more proximal large intestinal, colonic primaries, which met TO the liver.

I've been on this board for a good part of a year and I am continuously impressed with how smart some of you are. I'm no dummy, but you guys seem to grasp these concepts much easier than I do. (Do you have science backgrounds?) Thanks for sharing and for dumbing it down for some of us. :-)

Yes some of us do have science back grounds. I spent 20 years doing drug discovery for the most part in Anti-Cancer drug research and now do cheminformatics / knowledge management. Unfortunately I don't have the same resources available to me that I once had to follow the research.
