Introduction: Wilms tumor therapy in low- and middle-income countries (LMICs) relies on treatment protocols adapted to resource limitations, but these protocols have rarely been evaluated in real-world settings. Such evaluations are necessary to identify high-impact research priorities for clinical and implementation trials in LMICs. The purpose of this study was to identify highest priority targets for future clinical and implementation trials in sub-Saharan Africa by assessing outcomes of a resource-adapted treatment protocol in Malawi., Methods: We conducted a retrospective cohort study of children treated for Wilms tumor with an adapted SIOP-backbone protocol in Lilongwe, Malawi between 2016 and 2021. Survival analysis assessed variables associated with poor outcome with high potential for future research and intervention., Results: We identified 136 patients, most commonly with stage III (n = 35; 25.7%) or IV disease (n = 35; 25.7%). Two-year event-free survival (EFS) was 54% for stage I/II, 51% for stage III, and 13% for stage IV. A single patient with stage V disease survived to 1 year. Treatment abandonment occurred in 36 (26.5%) patients. Radiotherapy was indicated for 55 (40.4%), among whom three received it. Of these 55 patients, 2-year EFS was 31%. Of 14 patients with persistent metastatic pulmonary disease at the time of nephrectomy, none survived to 2 years. Notable variables independently associated with survival were severe acute malnutrition (hazard ratio [HR]: 1.9), increasing tumor stage (HR: 1.5), and vena cava involvement (HR: 3.1)., Conclusion: High-impact targets for clinical and implementation trials in low-resource settings include treatment abandonment, late presentation, and approaches optimized for healthcare systems with persistently unavailable radiotherapy., (© 2023 Wiley Periodicals LLC.)

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 8-17 years with SCD attending the pediatric hematology clinic at Kamuzu Central Hospital (KCH) in Lilongwe, Malawi., Methods: A mixed-methods cross-sectional study was conducted at KCH. Patient data were collected with the aid of a standardized case report form. HRQoL was assessed using PedsQL™ Sickle Cell Disease Module by the 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 were analyzed using content thematic analysis., Results: A hundred and sixty-three children with SCD were enrolled and 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 .034) and low hemoglobin levels (β-coefficient 2.29 CI (.65-3.91); p value .006)., Conclusion: The HRQoL of this population is low. Pain and low hemoglobin were significantly associated with low HRQoL scores. Adequate treatment to control pain and increase the steady-state hemoglobin may improve the HRQoL of children with SCD. Interventions to address low emotional scores are recommended., (© 2022 Wiley Periodicals LLC.)

Background: Burkitt lymphoma (BL) accounts for 90% of pediatric lymphomas in sub-Saharan Africa. Plasmodium falciparum malaria is considered an etiological factor of BL. We describe the geographic distribution of pediatric BL in Malawi and association with P. falciparum malaria prevalence rate (PfPR)., Methods: We enrolled 220 pathologically confirmed incident pediatric BL cases (2013-2018) into an observational clinical cohort at Kamuzu Central Hospital (KCH) in Lilongwe district. KCH is the main tertiary cancer referral center serving the central and northern regions of Malawi. Using an ecological study design, we calculated district-level annual BL incidence rate using census population estimates. District-level PfPR was extracted from the National Malaria Control Program 2010 report. BL incidence and PfPR maps were constructed in QGIS. Moran's I  test was used to identify BL spatial clusters. Pearson's correlation and multiple linear regression analyses were used to statistically examine the relationship between PfPR and BL., Results: BL incidence was higher in central region districts (8.2 cases per million) than northern districts (2.9 cases per million) and was elevated in lakeshore districts. Districts with elevated PfPR tended to have elevated BL incidence. A low-risk BL cluster was detected in the north. Statistically, BL incidence was positively correlated with PfPR (r = .77, p < .01). A 1% increase in PfPR predicted an increase in BL incidence of 0.2 cases per million (p = .03), when controlling for travel time from referral district hospital to KCH., Conclusion: Our study supports evidence for an association between P. falciparum and BL and highlights a need to improve geographic accessibility to tertiary cancer services in Malawi's northern region., (© 2022 Wiley Periodicals LLC.)

Background: Patient-reportedoutcomes (PROs) that assess health-related quality of life (HRQoL) are increasingly important components of cancer care and research that are infrequently used in sub-Saharan Africa (SSA)., Methods: We administered the Chichewa Pediatric Patient-Reported Outcome Measurement Information System Pediatric (PROMIS)-25 at diagnosis, active treatment, and follow-up among pediatric lymphoma patients in Lilongwe, Malawi. Mean scores were calculated for the six PROMIS-25 HRQoL domains (Mobility, Anxiety, Depressive Symptoms, Fatigue, Peer Relationships, Pain Interference). Differences in HRQoL throughout treatment were compared using the minimally important difference (MID) and an ANOVA analysis. Kaplan-Meier survival estimates and Cox hazard ratios for mortality are reported., Results: Seventy-five children completed PROMIS-25 surveys at diagnosis, 35 (47%) during active treatment, and 24 (32%) at follow-up. The majority of patients died (n = 37, 49%) or were lost to follow-up (n = 6, 8%). Most (n = 51, 68%) were male, median age was 10 (interquartile range [IQR] 8-12), 48/73 (66%) presented with advanced stage III/IV, 61 (81%) were diagnosed with Burkitt lymphoma and 14 (19%) Hodgkin lymphoma. At diagnosis, HRQoL was poor across all domains, except for Peer Relationships. Improvements in HRQoL during active treatment and follow-up exceeded the MID. On exploratory analysis, fair-poor PROMIS Mobility <40 and severe Pain Intensity = 10 at diagnosis were associated with increased mortality risk and worse survival, but were not statistically significant., Conclusions: Pediatric lymphoma patients in Malawi present with poor HRQoL that improves throughout treatment and survivorship. Baseline PROMIS scores may provide important prognostic information. PROs offer an opportunity to include patient voices and prioritize holistic patient-centered care in low-resource settings., (© 2021 Wiley Periodicals LLC.)
