Cancer risk among Holocaust survivors in Israel—A nationwide study

Abstract

BACKGROUND: Holocaust survivors during World War II were exposed to various factors that are associated with cancer risk. The objective of this study was to determine whether Holocaust survivors had an increased risk for developing cancer. METHODS: The study population included 152,622 survivors. The main analysis was based on a comparison between individuals who were entitled to compensation for suffering persecution during the war and individuals who were denied such compensation. A complementary analysis compared survivors who were born in countries governed by Nazi Germany with survivors born in nonoccupied countries. A Cox proportional hazards model was used, with the time at risk of cancer development starting on either January 1, 1960, or the date of immigration to the date of cancer diagnosis or death or the date of last follow-up (December 31, 2006). RESULTS: Cancer was diagnosed in 22.2% of those who were granted compensation versus 16% of those who were denied compensation (P
