These findings highlight families at risk for treatment abandonment, underlying reasons, and opportunities to improve retention in care for pediatric cancer patients in SSA.

Translation and cultural validation of the PROMIS-25 into Chichewa for Malawi was successful. Baseline HRQoL for patients with pediatric lymphoma in Malawi is poor for all domains except peer relationships. This emphasizes an urgent need to address HRQoL among children undergoing cancer treatment in SSA using self-reported instruments validated within the local context.

The majority of African children with cancer die without access to resources. We describe efforts to build a public treatment program with curative intent for childhood cancer in Lilongwe, Malawi despite severe limitations in diagnostic and therapeutic resources. We retrospectively analyzed a cohort of childhood cancer patients at Kamuzu Central Hospital from 12/2011-6/2013. Consistently available chemotherapeutic agents were limited to cyclophosphamide, vincristine, doxorubicin, bleomycin, methotrexate, and prednisone. Of 258 newly diagnosed childhood malignancies, 17 patients with retinoblastoma were excluded from clinical analyses due to insufficient clinical data. Among the remainder of the cohort (n = 241), 42% were female with median age 8.4 years (range 0.6-17.9). Forty-six (19%) were HIV-infected (42 Kaposi sarcoma, 3 Burkitt lymphoma, 1 Hodgkin lymphoma). The most common clinical presentations were palpable abdominal mass (41%), peripheral lymphadenopathy (33%), and jaw mass (17%). Nearly two-thirds of total diagnoses were accounted for by Burkitt lymphoma (n = 74), Kaposi sarcoma (n = 52), Hodgkin lymphoma (n = 21), and Wilms tumor (n = 19). Twelve-month overall survival for these 4 most common diagnoses was 54% (95% confidence interval 46-61) versus 19% (95% confidence interval 11-30) for all other diagnoses (median follow-up 19 months). Treatment-related mortality was highest in patients with non-Wilms solid tumors of the abdomen (48% versus 10% for the overall cohort, p < 0.001), while treatment abandonment was highest in patients with bone and soft-tissue sarcomas (29% versus 14% overall, p = 0.05). Childhood cancers with excellent curative potential accounted for the majority of patients, establishing an opportunity to build treatment programs with curative intent despite severe limitations.

Purpose Wilms tumor is a common renal cancer of childhood with long-term survival rates exceeding 80% in high-resource countries, yet survival remains below 50% in the low-resource settings of Africa. We assessed outcomes of a resource-adapted treatment protocol at a Malawian hospital to identify actionable factors affecting survival. Methods: We assessed clinical outcomes with a single-center retrospective cohort study of children diagnosed between 2016 and 2021 in Lilongwe, Malawi. Findings: We identified 136 patients with Wilms tumor, most commonly with stage III (25.7%) or IV disease (25.7%). Two-year overall survival (OS) was: Stage I, 78%; Stage II, 27%; Stage III, 62%; Stage IV, 23%, Stage V, 0%. Event-free survival (EFS) was: Stage I, 60%; Stage II, 0%; Stage III, 51%; Stage IV, 13%; Stage V, 0%. After death, treatment abandonment was the most common event comprising EFS, occurring in 26.5% of patients. Among 43% of patients who completed therapy, 2-year OS was 80% and EFS was 69%. Relapse was documented in 9.6% of patients. Radiotherapy was indicated for 40.4% patients, among whom only three received it due to regional unavailability. Factors associated with OS were severe acute malnutrition (Hazard ratio, HR, 1.9), increasing tumor stage (HR, 1.5), and inferior vena cava involvement (HR, 2.7). On multivariable analysis, only tumor stage remained associated with outcome. Interpretation Implementing a curative resource-adapted treatment protocol in an extremely resourced-constrained environment was feasible in Malawi and resulted in relatively favorable outcomes in low-stage disease, particularly among those who completed therapy. However, factors such as late-stage disease, frequent abandonment, and absent radiotherapy represent ongoing implementation barriers that should be the focus of continued research funding and intervention in Africa.

Background: Sickle cell disease (SCD) is characterized by both acute and chronic complications that affect the daily lives of patients and lower their quality of life. Objective: To describe the health-related quality of life (HRQoL) and the associated factors in children aged 8 to 17 with SCD attending the paediatric haematology clinic at Kamuzu Central Hospital (KCH) in Lilongwe, Malawi. Methods: A mixed methods cross sectional study was conducted at KCH. Patient data was collected with the aid of a standardized case report form. HRQoL was assessed using PedsQL™ Sickle Cell Disease Module by child’s report. Associations between HRQoL scores and independent variables were evaluated by a linear regression model. In-depth interviews were then carried out and the qualitative data was analyzed using content thematic analysis. Results: A hundred and sixty-three children with SCD were enrolled, 52.1% were females. Their median age was 11.2±2.7 years. The mean global HRQoL score of the children was 62±17.3. The highest scores were in the treatment domain (72.5±15.1) while the lowest scores were in the emotions domain (55.2±28.7). The mean pain score was 58.8±16.3. The factors associated with low HRQoL scores were pain (β-coefficient -6.97 CI (-3.07,-15.58); p value 0.034) and low haemoglobin levels (β-coefficient 2.29 CI (0.65-3.91); p value 0.006 ). Conclusion: The HRQoL of this population is low. Pain and low hemoglobin were significantly associated with low HRQoL scores. A biopsychosocial model of heath care delivery and health campaigns are recommended to improve the HRQoL of the children.
