Welcome to ESOCAN

An educational resource dedicated to the
prevention and control of esophageal cancer.

Each year over one half million people in the world are diagnosed with esophageal cancer. Unfortunately most do not survive more than a year, making it the sixth most common cause of cancer-related death. Much is known about the risk and protective factors for this cancer, providing opportunities for prevention through avoiding causative exposures, engaging in healthy activities, chemoprevention and, in some cases, screening for precancerous conditions.

The purpose of this site is to promote awareness of esophageal cancer, summarize it's epidemiology (see background and risk and preventive factors) and demonstrate how this information can be used for personalized cancer prevention. See Learn More below and menu tab. Additional information resources can be found in a menu tab as well.

The BEACON consortium tab summarizes findings from this research consortium which was founded in 2005 to study causes of EAC.

‍New research findings relevant to these issues will be highlighted from time to time in the blog. If you would like updates delivered to your inbox (1 - 2 per month), sign up for the newsletter.

Recent News:

Three-tiered screening program proposed
Drs. Yusuf and Fitzgerald review recent technological advancements in screening for Barrett's esophagus and propose a three-tier approach using risk prediction algorithms and minimally invasive approaches to improving detection rate for Barrett's and EAC
Review of Barrett's and Esophageal Adenocarcinoma
The authors review the incidence of BE and EAC and associated risk factors, evidence for improved outcomes among patients with a prior diagnosis of BE compared to those without, discuss the challenges of developing sufficiently accurate prediction models in the context of high population prevalence of risk factors (e.g., obesity, reflux, smoking), and emphasize the need for larger biomarker studies.
Good news in treatment of esophageal cancer
Dr. Ilson's editorial in the New England Journal of Medicine puts new findings regarding the monoclonal antibody, nivolumab, in treatment of esophagal cancer in perspective. [Figure from original research article by Kelly, et al in same issue]
Review of world-wide GI cancer epidemiology
The authors extensively review the epidemiology (incidence, risk factors, prevention) of cancers of the colon, stomach and esophagus across China, the US and Europe
Dutch study on RFA/EMR effectiveness
In an observational study of 1154 patients with BE or early EAC, 94% achieved complete eradication after treatment with RFA/EMR. A dysplasia recurrence rate of 1% per year was observed over a median 43 months.
Modeling suggests a role for Cytosponge in post-RFA surveillance
This is one of the first examinations of the Cytosponge as a non-endoscopic method of surveillance in persons who have been treated for dysplasia in Barrett's. Results suggest that it may be more cost-effective than endoscopy.
