ABSTRACT
OBJECTIVE:
In this paper, we analyzed the frequency of childhood cancer in the Center of Tunisia during 1993-2006.DESIGN:
The different types of cancer were grouped according to the International Classification for Cancer in Children. The general and specific frequencies by age and by sex were analyzed.RESULTS:
A total of 727 new cases of childhood cancer were registered, with a male to-female sex ratio of 1.7/1. Leukemias had the highest frequency (27%) and, of these, lymphoid leukemias were the most prevalent (73.5%). Thereafter, in descending order of frequency, were lymphomas (25.7%), tumors of the central nervous system (CNS, 9.2%), neuroblastomas (7.7%), sarcomas (6.9%), carcinomas (6.3%), bone tumors (5.8%), nephroblastomas (5.5%), and germinal cell tumors (2.6%). The highest frequency of cancer was found at age 10-14 years (34.9%). Leukemias were the most frequent in age groups 1-4 and 5-9 years, whereas, neuroblastomas and lymphomas were the most frequent at age under one year and 10-14 years, respectively. Of those cases of solid tumors, 55.8% were diagnosed as having advanced stages of the disease.CONCLUSION:
Leukemias, lymphomas, and CNS tumors were the principal cancers in the Center of Tunisia. A childhood cancer registry with high-resolution data collection is advocated for in-depth analysis of pediatric malignancies.
