Malignant neoplasms in Jordanian children

Area of Science:

• Pediatric Oncology
• Epidemiology
• Cancer Research

Background:

• Childhood malignant diseases represent a significant global health concern.
• Understanding regional variations in pediatric cancer incidence is crucial for targeted interventions.
• Previous epidemiological data from Jordan and surrounding Arab countries regarding pediatric malignancies are limited.

Purpose of the Study:

• To analyze the incidence and types of malignant diseases diagnosed in children in Jordan between 1975 and 1979.
• To compare the epidemiological patterns of childhood cancers in Jordan with those reported in neighboring Arab countries and developed nations.

Main Methods:

• Retrospective analysis of 373 diagnosed cases of malignant disease in children.
• Data collection covered the 5-year period from 1975 to 1979.
• Classification of tumors based on established pathological criteria.

Main Results:

• Lymphomas were the most frequent pediatric malignancy (28.7%), followed by leukemias (19.6%) and brain tumors (16.1%).
• Within lymphomas, Hodgkin's disease, Burkitt's lymphoma, and lymphocytic lymphoma each accounted for approximately one-third of cases.
• Abdominal involvement was a common feature in children diagnosed with non-Hodgkin's lymphoma.

Conclusions:

• The epidemiological profile of childhood cancers in Jordan during 1975-79, particularly the high incidence of lymphomas, aligns with data from other Arab countries.
• This pattern contrasts with developed countries where leukemias and brain tumors are more prevalent in pediatric populations.
• Further research is warranted to explore the underlying reasons for these regional differences in childhood cancer epidemiology.
