I am truly sorry to read this. I will be praying for you, your husband, and your families. mets is hard to deal with, especially when told you had clean margins from surgery and went through radiation and chemo. You are told when you go through that they kill everything. But that's not always true. Some microscopic cells can withstand and it's not fair.
I hope that the chemo shrinks or at least keeps those spots at bay. I have a friend that was diagnosed with stage 4 brain cancer a year and a half ago. They did surgery, only got 80% of the tumor out. He went through radiation and he has been on chemo since the surgery. Tumor started to grow about 3 months ago, they changed the chemo he was on, and now it's shrinking again. So I will hope and pray that chemo helps or the trial does wonders for your husband.
Keep your chin up, sometimes life expectancies aren't always accurate.
