Meeting the challenge of hematologic malignancies in sub-Saharan Africa

Area of Science:

• Hematology
• Oncology
• Global Health

Background:

• Cancer, particularly hematologic malignancies, poses a significant and increasing threat in sub-Saharan Africa, projected to surpass infectious diseases.
• Hematologic cancers like non-Hodgkin lymphoma and leukemia are rising due to factors including Human Immunodeficiency Virus (HIV) prevalence.
• Existing infrastructure for diagnosing, treating, and managing hematologic disorders in the region is insufficient to meet the growing demand.

Purpose of the Study:

• To review the scope of hematologic malignancies in sub-Saharan Africa.
• To examine the impact of endemic infections (HIV, Epstein-Barr virus, malaria, KSHV) on these cancers.
• To identify limitations in current diagnostic and treatment modalities and propose a future agenda.

Main Methods:

• Literature review of hematologic malignancies in sub-Saharan Africa.
• Analysis of the influence of endemic infections on cancer incidence and progression.
• Evaluation of current healthcare system capabilities in hematopathology, treatment, and supportive care.

Main Results:

• Hematologic malignancies constitute a substantial portion of the cancer burden, with notable increases in specific lymphomas linked to HIV.
• Endemic infections significantly contribute to the burden and complexity of hematologic cancers.
• Critical gaps exist in hematopathology, chemotherapy, radiotherapy, stem cell transplantation, and palliative care.

Conclusions:

• Addressing the rising burden of hematologic cancers in sub-Saharan Africa requires a comprehensive strategy.
• Enhancing diagnostic capabilities, treatment accessibility, and supportive care is crucial.
• Sustained global collaboration and advocacy are essential for progress, mirroring successes in infectious disease control.
