My stepfather died from esophageal cancer.
It's nickname is "The Beast" because it is aggressive and usually goes undetected until later stages (usually 3 or 4) where the patient has physical issues with swallowing, etc.
My stepfather was losing weight--he thought it was because he was really watching, walking and eating VERY healthy--only fish, chicken, veggies & fruit. He was also told to take OTC meds for the reflux, etc.
He was officially diagnosed in Feb, (when he couldn't swallow--literally, which happened VERY quick--like in 1-2 days, and he was gone by December of that same year.
He was admitted and a mesh tube was placed in his esophagus so that he could manage a liquid soft diet until they could get him to surgery and a feeding tube.
His surgeon was a "god"...a very talented & well respected thoracic surgeon that removed the cancerous part of his esophagus and reattached it, etc. It was a brutal, almost barbaric surgery & recovery, which required a feeding tube for a time, but a success! We exhaled.
His oncologist recommended follow up chemo because O. lymph node (in his neck) tested positive for cancer. He battled through the chemo which was no picnic but he accomplished it.
By July, he was well enough that we all went to the beach for a nice vacation, and we were amazed at how good he felt and how well he was able to eat/swallow, etc!
In August, he had a follow up pet scan and the esophageal cancer had metastasized to his liver. Not good. He went through some chemo but it was not effective.
I will never forget what my neighbor (an RN) said when I said he was going to have chemo following the surgery--she said "Oh....ok....it's just that it seems like chemo can stir things up in other areas...." Those words still echo in my mind! But I'm sure when you're the patient and the oncologist tells you that xyz is the best course of action....you do xyz, right? I wonder all the time what would have happened if he had stopped at the surgical treatment.
Anyway, he died in December about a week before his 75th birthday. A man who, until then, was healthy as a horse, physically active and listed "Tylenol" when asked what medications he was "on" currently.
He eventually decided to stop the chemo because ti was just so hard on him and, like I said, no positive effects shown.
I will pray for your dad and remember, every patient IS different. This was all about 6 years ago and research is being done every day.
