Epidemiology of pediatric cancers in Iran

Abstract

Ies are the most frequent causes of mortality in children aged 1-16 years. In an epidemiologic study, all cases of pediatric cancer (Aged 1-16 years) registered by the medical universities in Iran are studied regarding the age, sex and type of the malignancy. This study refers to the cancer cases diagnosed and histopathologically confirmed in 1996. Of the data received from 9 provinces, a frequency of cancer in 420 children (58.3% male, 41.7% female) with a median age of 7.1 years was established. Hematologic malignancies with 20% of all cases were the most frequently encountered cancer types. The next cases consisted of brain (15%), lymph nodes (15%), bone (8%), kidney (7%), ophthalmic (6%), and soft tissue (5%) malignancies.
