Worldwide trends in esophageal cancer survival, by sub-site, morphology, and sex: an analysis of 696,974 adults diagnosed in 60 countries during 2000-2014 (CONCORD-3).

Esophageal cancer survival remains poor in many countries. The distributions of sub-site and morphological sub-type vary between countries, but these differences do not fully explain international variation in esophageal cancer survival.
