A Snapshot of Esophageal Cancer

Incidence and Mortality

Esophageal cancer consists of two primary cancer types, esophageal adenocarcinoma and esophageal squamous cell carcinoma. Esophageal adenocarcinoma is more common in the United States. Men of all racial and ethnic groups have higher esophageal cancer incidence and mortality rates than women. Historically, African American men have had higher esophageal cancer incidence and mortality rates than white men; however, increasing incidence and mortality rates in white men and a steady decline among African American men in the past decade have reversed this trend. A downward trend in mortality has not been observed for any other racial/ethnic group.

Risk factors for esophageal cancer include tobacco use, alcohol use, having Barrett's esophagus or gastric reflux disease, and increasing age. Common signs of esophageal cancer include painful or difficult swallowing and unexplained weight loss. There are no standard or routine screening tests for esophageal cancer. Tests and procedures that are used to detect and diagnose esophageal cancer include a physical examination, upper endoscopy, chest x-ray, and a barium swallow test. Standard treatment options for esophageal cancer include surgery, radiation therapy, chemotherapy, chemoradiation therapy, laser therapy, and electrocoagulation.

Assuming that incidence and survival rates follow recent trends, it is estimated that $1.6 billion1 will be spent on esophageal cancer care in the United States in 2014.  

Line graphs showing U.S. Esophageal Cancer Incidence and mortality per 100,000, by race and gender.  Incidence from 1991-2011 and mortality from 1990-2010 is shown. In 2011, white males have the highest incidence, followed by African American males, African American females, and white females. In 2010, white males have the highest mortality, followed by African-American males, African American females, and white females.

  • A genome-wide association study of esophageal adenocarcinoma and Barrett's esophagus identified three new susceptibility loci for their development. Published October 2013. [PubMed Abstract]
  • HER2 protein expression and gene amplification are highly concordant in patients with esophageal adenocarcinoma. HER2 expression was also positively associated the expression of its partner, HER3, in esophageal adenocarcinoma supporting ongoing therapeutic efforts to target this interaction. Published October 2013. [PubMed Abstract]
  • In a retrospective case-control study, statin use was associated with a reduced risk of Barrett's esophagus, especially in obese patients. Published May 2014. [PubMed Abstract]
  • A comprehensive genomic comparison of two potential precursor tissues for esophageal adenocarcinoma—intestinal metaplasia (IM) and nongoblet cell metaplasia— (NGM), showed that IM has a much higher frequency of cancer-associated mutations than NGM. Published July 2014. [PubMed Abstract]

Trends in NCI Funding for Esophageal Cancer Research

NCI’s investment2 in esophageal cancer research was $26.5 million in fiscal year (FY) 2013. In addition to the funding described in the graph, NCI supported $6.0 million in esophageal cancer research in FYs 2009 and 2010 using funding from the American Recovery and Reinvestment Act.

FY 2010, $30.5 million Esophageal Cancer Funding of $5.10 billion Total NCI Budget. FY 2011, $33.0 million Esophageal Cancer Funding of $5.06 billion Total NCI Budget. FY 2012, $28.0 million Esophageal Cancer Funding of $5.07 billion Total NCI Budget.  FY 2013, $26.5 million Esophageal Cancer Funding of $4.79 billion Total NCI Budget.
