Purpose: Our goal was to describe adolescent cancer incidence and survival in Israel, and to identify demographic and epidemiologic variations among adolescents with cancer.
Patients and methods: We used data from the Israel National Cancer Registry in order to examine the incidence and survival of adolescent cancer in Israeli adolescents aged 15-19 years, diagnosed during the years 1998-2009. Cases were analyzed according to sex, ethnicity and geographical region, as well as comparison to other countries in the region and other western countries.
Results: Among the 1,532 new cases of adolescent cancer, there was a total incidence rate of 226 cases per million. The incidence rate for males was higher than for females (230 and 222, respectively) and higher for Jewish adolescents than for Arab adolescents (235 and 194, respectively). The largest groups were Lymphomas (69 per million), Malignant Epithelial Neoplasms (49 per million), and Leukemias (21 per million). We estimated the survival probability updated to December 2009, and calculated the 5-year survival for new cases until the end of 2004. The overall survival at 5 years was 78%, with 62% for the Arabic population and 81% for the Jewish population, dependent on the diagnosis.
Conclusions: The results of this study show little difference in the predominance of some adolescent cancers in comparison with other developed countries. This study may add more information for further investigation of the genetic and environmental factors that cause adolescent cancer in Israel. As well as delineate the genetic basis for ethnic origin disparities in survival.
