The worldwide burden of esophageal cancer (for both sexes) was estimated in 2002 [1] as 462 000 new cases and 386 000 deaths; the high ratio (0.83) of mortality to incidence confirms a poor prognosis. Asiatic countries share most of the burden with 362 000 new cases annually and 293 000 deaths. Using an age-standardized rate (ASR), incidence is estimated worldwide at 11.5 per 100 000 in men and 4.7 per 100 000 in women. Much higher rates occur in certain regions of Asia, such as Cixian in China ([Table 1]), and of Africa [2].

Table 1 Incidence (age-standardized rate [ASR] per 100 000, world population) of esophageal cancer in registries in China for the period 1993 - 97. (From Parkin et al., Cancer incidence in five continents. IARC publication no.155, Lyon: IARC Press; 2002 2) Men Women Beijing 10.2 4.0 Changle 30.1 8.9 Cixian 183.8 123.1 Hong Kong 11.7 2.5 Jiashan 20.7 5.3 Qidong 13.2 3.9 Shanghai 8.2 4.2 Taiwan 7.9 0.8 Tianjin 11.0 4.1 Wuhan 13.3 4.9

Most cases are squamous cell carcinomas (SCC); adenocarcinoma (ADC) in Barrett esophagus is less frequent, although its incidence is on the rise in several high-resource countries. Reliable data on histology are found in registries in which the proportion of unspecified cases is small ([Tables 2] and [3]). Tumors at the esophagogastric junction are often misclassified between the distal esophagus or the gastric cardia.

In the USA the data are reported for black and white ethnic groupings. Other tumors are not listed here. (From Parkin et al., Cancer incidence in five continents.
