[Management problems of malignant hemopathies among children in Senegal].
Malignant hemopathies are not considered as public health priority in Senegal because of their infrequency in comparison with infections and malnutrition. However they remain usually lethal instead of a great improvement of their prognosis in suitable therapeutic conditions. The objective of this study was to determine the epidemiologic and evolutionnal profile of these pathologies, and identify practical management problems in a reference public pediatric service in Senegal. We retrospectively analysed hospitals registers and records of all patients followed up in Albert Royer Children Hospital of Dakar from january 1989 to december 1998. During this ten years period 25 cases of malignant hemopathies were diagnosed among 32,789 hospitalised children, representing an hospital prevalence of 0.08 per cent. Mean age at the desease diagnosis was 9.5 years and sex ratio 2.57 (18 boys and 7 girls). The malignant type was acute leukemia (AL) in 11 cases (44%) including 9 cases of of acute lymphoblastic leukemia (ALL) and 2 cases of acute myeloblastic leukemia (AML); chronic myeloid leukemia (CML) in 2 cases (8%), Hodgkin's desease (HD) in 9 cases (36%) and non hodgkinian lymphoma (NHL) in 3 cases. NHLwere Burkitt type in 2casesand lymphoblastic type in 1 case. Their was no maxillary or facial localisation in Burkitt type lymphoma. The mean duration between the first clinical symptomes and the diagnosis of the disease was 4 months and delayed diagnosis was mainly due to delayed transfer from peripheral health services to hospital. Among 19 patients whose records were available, 17 were subjected to chemotherapy. However reference protocols were completely applyed in only 2 cases, one with HD and an other with lymphoblastic lymphoma. Transfusion managementwas not sufficient because of the lack of blood derived products (packed platelets or leucocytes) when needed. Thirteen patients died while followed up and mean survival after first hospitalisation in these cases was 120 days in ALL, 38 days in AML, 2.5 years in HD and 18 months in NHL The other patients were lost of sight and presumed to be dead at home. Eventually, this study showed that, in our hospital, children with malignant hemopathies did not derive benefit of therapeutic progress enregistered long time ago in developed countries, since they remain constantly lethal. The main factors of lethality could be delayed transfer to hospital because of lack of knowledge about these pathologies in the peripheral health services and poor therapeutic conditions in reference hospitals. Creation of specialised clinical haematology department could enable us to improve the prognosis of these affections by an optimal use of available human and material ressources.
