Twenty-five Zambians with leukaemias

Area of Science:

• Hematology
• Oncology
• Epidemiology

Background:

• Leukemia diagnosis rates in sub-Saharan Africa are often underestimated.
• Limited data exists on leukemia demographics in Zambia.
• Chronic lymphatic leukemia (CLL) is a significant hematologic malignancy.

Purpose of the Study:

• To describe the incidence and demographic characteristics of leukemia cases in Ndola, Zambia.
• To compare leukemia patterns in Zambia with other sub-Saharan African regions.
• To explore potential etiological factors for CLL in young adults.

Main Methods:

• Retrospective analysis of leukemia diagnoses over a three-year period in Ndola.
• Data collection on patient age, sex, and leukemia type.
• Comparison of demographic data with existing literature from similar regions.

Main Results:

• Twenty-five leukemia cases were diagnosed over three years.
• Acute leukemias were likely under-diagnosed, particularly in children.
• Chronic lymphatic leukemia (CLL) was the most frequent type, affecting 13 individuals (6 males, 7 females).
• A notable proportion of CLL cases (5/13) were under 45 years old.

Conclusions:

• Leukemia incidence in Ndola shows similarities to other sub-Saharan African countries.
• The age and sex distribution of leukemia in Zambia warrants further investigation.
• A potential retroviral etiology for CLL in young adults is hypothesized and requires further research.
