Trends in the incidence rate of uveal melanoma in Israel during the period 1961-1989 among Jews of various geographical origins and among non-Jews were examined, and found to be stable over time. Based on data of the Israel Cancer Registry, 515 cases were included in the final study population after an independent case-finding ascertainment survey. The average annual incidence rate per million for all Jews was 5.7 for both males and females; the rates for non-Jews were: males 1.6, females 1.3. Incidence rates within the Jewish sub-populations show significant differences. The highest rates by sub-population were for Jews born in Europe or America (7.5 for males and for females), followed by Jews born in Israel (males 6.8, females 6.7); and lowest in Jews born in Africa (males 2.1, females 2.3) and Asia (males 1.6, females 2.8). Jews born in Israel had rates lower than Jews born in Europe and America during the 1960s, but in the 1980s the situation was reversed. Results suggest that rate differences between population groups and over time stem from constitutional factors or from the direct or indirect effect of sunlight radiation, whether early in life or from cumulative exposure.
The magnitude and dynamics of lung cancer incidence in Jews and Arabs in Israel between the years 1962 and 1982 were studied. In general, age-standardized incidence rates increased consistently between the years 1962 and 1976 among Jewish (24% increase) and Arab (39%) males, and to a lesser degree among Jewish females (15%). Arab females had the highest (77%) increase. From 1977 to 1982 a general decrease in incidence rates, which was largest among Arab males (19%) and females (15%), was noted. Rates among Jewish males are currently 26% higher than among Arab males, and are 162% higher among Jewish females than in Arab females. Lung cancer rates in both males and females in Israel (Jews and Arabs) are lower than in most developed countries in the world. Among the possible reasons are differences in the population risk factors profile, availability of health care and the level of diagnosis and ascertainment of cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
