A Transformative Decade: An Evaluation of the Francophone African Group of Pediatric Oncology's Training Program (2014-2024).

Childhood cancer in Africa faces significant challenges due to workforce shortages and limited training opportunities. The French African Group for Pediatric Oncology (GFAOP) established the African School of Pediatric Oncology and introduced a pediatric oncology teaching called the "Diplome Universitaire de Cancérologie Pédiatrique" (DUCP) training program. This report evaluates the contributions of the DUCP program to pediatric oncology in Africa and discusses the sustainability of the program. The DUCP program trained six cohorts of healthcare professionals from French-speaking African countries since 2014. An evaluation was done on the participant demographics and regional contributions. Data were collected from trainee records and DUCP records. The DUCP program was evaluated based on the domains developed by the Education Program Assessment Tool (EPAT). Over the 10-year period, the DUCP program trained 107 healthcare professionals from 20 Francophone countries of which 99% were retained in Africa. Of the 83 graduates, 55 (66%) actively practice in pediatric oncology. Of the 18 francophone countries, 17 countries increased the number of pediatric oncologists and 16 improved the ratio of pediatric oncologists to children under 15 years. Nine new pediatric oncology services were established by the graduates thus far. Despite challenges, such as the COVID-19 pandemic, the program remains sustainable because of continued financial support, collaborations with the international pediatric oncology community, and adapting the program content to participant and local setting needs. Retention of graduates in childhood cancer services remains a challenge that necessitates governmental involvement. The DUCP program is impactful and sustainable and improves access for children to cancer services in Africa. By fostering continued collaboration with governments, addressing the needs of an increasing African population, and expanding support for similar initiatives, the program's longevity and positive impact can be further ensured.

Human leukocyte antigen immunization in transfusion-dependent Moroccan patients with beta-thalassemia major: prevalence and risk factors.

INTRODUCTION: Beta-thalassemia major patients need a regular blood transfusion to have an initial normal growth. However, these patients have an increased risk of developing alloantibodies. Our main goal was to study HLA alloimmunization in Moroccan Beta-thalassemia patients by confronting it with transfusion and demographic criteria, exploring the involvement of HLA typing profile in the development of HLA antibodies and in turn determining risk factors for their development. METHODS: The study consisted of 53 Moroccan pediatric patients with Beta-thalassemia major. Screening for HLA alloantibodies was performed using Luminex technology Whereas HLA genotyping was done with sequence-specific primers (PCR-SSP). RESULTS: In this study, 50.9% of patients have been identified as positive for HLA antibodies, with 59.3% having both HLA Class I and Class II antibodies. A significant increase frequency of DRB1*11 allele was revealed in non-immunized patients (34.6% vs. 0%, p = 0.001). Our results also revealed that the majority of our HLA immunized patients were women (72.4% vs. 27.6%, p = 0.001), and transfused with more than 300 units of RBC units (66.7% vs. 33.3%, p = 0.02). There were statistically significant differences when comparing these frequencies. CONCLUSIONS: This paper revealed that the transfusion dependent Beta-thalassemia major patients are exposed to risk of developing HLA antibodies following transfusions with leukoreduced RBC units. The HLA DRB1*11 was a protective factor against HLA alloimmunization in our beta-thalassemia major patients.

Guidelines from the SFGM-TC]. / Leucémie aiguë lymphoblastique dans les pays en voie de développement : prise en charge dès l'indication de greffe jusqu'au suivi post-greffe. Recommandations de la SFGM-TC.

Management of acute lymphoblastic leukemia (ALL) patients in countries with limited resources depends on the means of prognostic stratification, available treatment and logistics. During the 12th annual harmonization workshops of the francophone Society of bone marrow transplantation and cellular therapy (SFGM-TC), a designated working group reviewed the literature in order to elaborate unified guidelines for allogeneic hematopoietic cell transplantation (Allo-HCT) in this disease. Conventional poor prognostic factors can be used to determine the indication of allo-HCT in first remission. Patients lacking a HLA-matched related donor can be allografted with a haploidentical donor allo-HCT if available. Chemotherapy based conditioning regimen can be used if TBI is not available, because the probability to find a radiotherapy department with the capacity for total body irradiation is low. For patients with Philadelphia chromosome positive (Phi+) ALL, post-transplantation tyrosine kinase inhibitors as a systematic maintenance strategy is recommended. Autologous HCT is optional for Phi+ ALL patients with negative minimal residual disease, who not eligible for allo-HCT. Patients with refractory/relapsed disease have a poor prognosis which highlights the importance of acquiring in the future new therapies such as: blinatumumab, inotuzumab, and CAR-T cells.

Primitive myxoid mesenchymal tumor of infancy: Case report and review of the literature.

Primitive myxoid mesenchymal tumor of infancy (PMMTI) is an extremely rare soft tissue tumor with only a few cases. Herein, we report a case of 5-months-old girl presenting with a soft tissue mass on the sole of the left foot that recurred 2months after a first resection. The Doppler ultrasound imaging showed abundant blood flow in the tumor. Magnetic resonance imaging (MRI) showed a well demarcated tumor on the sole of the left foot. The surgically resected tumor consisted of primitive mesenchymal tumor cells dispersed in a myxoid background with delicate small blood vessels. Immunohistochemically, tumor cells expressed vimentin but were negative for AE1/AE3, Desmin, Muscle-Specific Actin, MyoD1, Myogenin, CD34, S-100 protein and CD99. Fluorescence in situ hybridization (FISH) showed absence of chromosomal translocation involving SYT and ETV6. Thus, the patient was diagnosed with a primitive myxoid mesenchymal tumor of infancy. To our knowledge, this is the first case of PMMTI affecting the sole of the foot.

Hematopoietic cell transplantation (HCT) is the curative treatment for many malignant and non-malignant blood disorders and some solid cancers. However, transplant procedures are considered tertiary level care requiring a high degree of technicality and expertise and generating very high costs for hospital structures in developing countries as well as for patients without health insurance. During the 11th annual harmonization workshops of the francophone Society of bone marrow transplantation and cellular therapy (SFGM-TC), a designated working group reviewed the literature in order to elaborate unified guidelines, for developing the transplant activity in emerging countries. Access to infrastructure must comply with international standards and therefore requires a hospital system already in place, capable of accommodating and supporting the HCT activity. In addition, the commitment of the state and the establishment for the financing of the project seems essential.
