I'm hesitating about whether to post here because I have a lot of experience of this but not with a good outcome, I'm afraid. However, I always preferred to know the facts and what I was dealing with so I'll be frank. If you'd rather not read on, I understand.
My dad was diagnosed with oesophageal cancer in July 2002 and we were told not to expect him to be there at Christmas. Against the odds, he reacted incredibly well to the first round of chemo and went into remission for four years. Unfortunately, it did come back and he started chemo again.
At the same time, my DH was diagnosed with the same thing. I couldn't believe fate could be so cruel but there you go. Dad's tumour was high in the oesophagus, DH's was at the bottom, spreading into his stomach. Dad didn't have too much trouble swallowing until the very end and, as a result, didn't lose a lot of weight. In fact, Mum put him on a high-calorie diet and he gained weight. DH lost weight rapidly as his swallowing was badly affected from the beginning and we struggled to get food into him. However, given that Dad had done so well with his first round of chemo, we were optimistic about DH but his first course only bought him six months before the tumours started to grow again. They tried two more courses, plus radiotherapy, but it didn't work. We lost Dad in November 2007 and DH died in August 2008.
In both cases, the cancer had already spread to the liver and lymph nodes at the time it was diagnosed. Unfortunately, this is quite often the case as oesphageal cancer doesn't show symptoms until it's already quite advanced. Our consultant's words were "if you're going to have cancer, this is one of the ones you don't want to have." Because of the secondary tumours, they ruled out operating on the oesophageal tumours in both cases.
I'm so sorry you are going through this and I wish I could give you something more positive. Please do remember that my experience was some years ago and things move rapidly so there will almost certainly be more options and treatments available to you now. I will also leave you with a positive outcome. My mum has a neighbour, well into her 70s, who had oesophageal cancer many, many years ago. She had her tumour (and part of the oesophagus) removed surgically and has been cancer-free ever since.
If there is anything at all I can do for you - advice, a shoulder to cry on, someone to rant with about the unfairness of it all - please, please PM me. Sending much love your way.
