I posted a Swedish study a few days ago which showed a correlation between heartburn symptom severity, frequency and duration and esophageal adenocarcinoma. The study found that these were more important than the esophageal mucosal state (barrett's, esophagitis, or normal) in correlation with cancer.
My dr., who I was referred to from Mayo clinic, told me that he knows the people who did the study (Lundgregen (Sp?), and that it has since been discredited. In essence, since Barrett's was only discovered in the 70's, in the 90's it was still relatively easy for endoscopists to miss. It is believed that those from this study that got cancer w/o Barrett's really did have a small area(s) of Barrett's that preceded the cancer.
In addition, the dr. said that a number of studies since have shown that barrett's is the mediator of adenocarcinoma, meaning "if you don't get Barrett's, you can't get cancer". As a side note he said a number of studies have also shown that if you don't get Barrett's within the first little while, due to a genetic marker of the disease, then you won't get it (or have like a 2% chance of getting it).
Just wanted to post this since I did post that study a few days back and it did get a bit of attention.
As another side-note, the dr. said brocolli sprouts really aren't proven to be anti-esophageal cancer. He said studies do exist where those who consume them get less cancer, but other studies exist where the same phyto-nutrients (sp?) and anti-oxidants are injected into the esophagus (drank?), and no benefit is found. He thinks it is because people who take the time to eat brocolli sprouts are also taking care of themselves in other ways, and that is why their risk is lower.
Either way I am going to eat sprouts, but just thought I'd let people know. He said there is nothing he knows of that can help prevention apart from eating very healthy and living healthy in a general sense.
