Sorry about your friend.
I don't know about others, but my esophagus not only contained a tumor at the base of the esophagus and top of my stomach, but my esophagus was very eroded from years of acid reflux. I am not sure, but I think they removed the 2/3 of my eso. as a precaution. Also, the radiation treatments I received caused a lot of scar tissue. In order to shrink the tumor and kill it so it could be removed, I received 30 radiation treatments and 8 once a week chemo. I have heard of many different ways to treat EC. Some get the surgery before chemo/rad and some get chemo/rad before surgery. My radiologist said he didn't believe I needed surgery, that they had completely killed the cancer, but he said, Do you want to be the first one to test it out? Naturally, I said no I'll have the surgery too.
If you have the time, go back through some of the posts. There is a lot of material on the message boards that will be helpful to you. Also, www.youtube.com/watch?v=mJ3Z7f7RlqA
I think this video might be helpful and there is one there about the minimally invasive technique that is becoming very popular.
