In 2018, it is estimated that more than 550,000 new cases of  esophageal  cancer (both types) will have occurred worldwide, making it the seventh most commonly occurring cancer and the sixth most common cause of cancer  death.1

In lower income regions, squamous cell carcinoma is by far the most common histological type. Particularly high rates occur in parts of China, Central Asia and Eastern Africa (figure 1.) In contrast, the United States and much of Western Europe and Australia has seen a remarkable rise in the incidence of esophageal adenocarcinoma (EAC)  which has transformed it from a relative rarity in the 1970s to the most common histological type of esophageal cancer in the U.S. today.2–5

Figure 2. EAC incindence in white males in U.S. 

EAC is most common among white males, in whom incidence has  increased about 10-fold in the U.S. since the early 1970s (figure 2.)6  Incidence rates in other groups also have risen, although from a much lower baseline rate. Like many solid tumors, EAC incidence rises rapidly with age (figure 3, left graph.) Persons diagnosed with  Barrett’s  esophagus are substantially more likely (about 20-fold at 60  years of  age) to develop EAC than the general population (figure 3,  right graph.)7

Figure 3. Incidence of EAC in U.S. In the general population (left graph) EAC is much more common among white males at all ages. Persons with Barrett’s esophagus (right graph) are at substantially higher risk of developing EAC (note the very different scales) than in the general population.7
