Reliable information about comparative cancer incidence in the Middle East has been lacking. The Middle East Cancer Consortium (MECC) has formed a network of population-based registries with standardized basic data. Here the age-adjusted cancer incidences are compared for four populations: Israeli Jews, Israeli non-Jews, Jordanians and the US Surveillance Epidemiology and End Results (SEER) population, for the years 1996-1997 (Israel) and 1996-1998 (other populations). The all-sites rate of cancer is approximately twice as high in Israeli Jews and SEER, compared with Israeli non-Jews and Jordanians. Rates of lung cancer are similar among Israeli Jews and non-Jews and about twice as high as in Jordanians. Childhood leukaemia rates in Jordan are higher than in Israeli Jews, but lower than SEER. Hodgkin lymphoma rates in Israeli non-Jews and Jordanians are similar to SEER, but non-Hodgkin lymphoma rates are lower than SEER. The previous suspicion of higher overall leukaemia and lymphoma rates in Jordan is thus not confirmed.

This project signals an advance in cancer registration in the Middle East region. While it is too early to declare a major breakthrough, significant strides have been made toward establishing a basis for reliable information on the cancer burden at a population level and future collaborative efforts in cancer epidemiologic research and prevention.
