Hi,
Not a great deal of experience but my dad has been diagnosed exactly the same. He has been battling cancer of the esophagus (adenocarcinoma) at stomach junction since Jan this year, last month we were told he now has new tumours in the liver after both chemo and radiotherapy have failed to do much good.
My dad is at the moment trying a therapy at a Centre for Integrated Medicine as conventional medicine has not helped him so far, only robbed him of his quality of life.
So I don't really have any advice as we are new to this situation too, just wanted to share that you are not alone.
I hope you find some answers xxx
