Abstract

Aim. This study aimed to determine the epidemiological, clinical, therapeutic profile of chronic lymphoid hemopathies (CLH) and the viral factors linked to the genesis of HLCs at the CHU-RN of Ndjamena in Chad. Methods. A descriptive cross-sectional study over two and a half years, from October 2017 to March 2020 at the Hematology Unit of the National Reference University Hospital Center (CHU-RN) of Ndjamena. Were included patients in whom the diagnosis of chronic lymphoid hemopathy had been made. Results. Ninety-eight (98) cases of hematological malignancies were recorded out of 531 hematological consultations including 66 (12.43%) CLH and 67.35% of hematological malignancies with an annual incidence of 26.4 cases. Chronic lymphocytic leukemia (CLL) was 56.06% (n=37) followed by 25.76% (n=17) Malignant non-Hodgkin's lymphoma, 15.15% (n=10) Hodgkin's lymphoma and 3.03 % (n=2) cutaneous lymphoma. A male predominance was observed for all types of CLH. The most represented age groups were those of 51 to 60 years for CLL and 11 to 20 years for lymphomas. Conclusion: This study made it possible to have a better epidemiological knowledge and the viral factors related to the genesis of CLH at the CHU- RN of Ndjamena. It revealed difficulties in biological diagnosis and management, in particular the initiation of chemotherapy.
