Thanks Colleen for you help. We won't know about the trial until mid-April, we have to show no disease progression on the new chemo we started (oxiplatin+5FU).
He has colon (MSS/wild type) metastatic to the liver, several tumors. Last time I asked our normal oncologist about operability she said they are doctors, not miracle workers. I have a little more faith than her, I know there are miracle workers out there. If we can't be taken in Canada, US is our next stop, but seems that the insurance/cost will be challenging, even though he's a US citizen and only moved to Canada in 2021 to be with me. Thanks for you help, remaining hopeful and hopefully Susan159 is doing well.
