Background: Approximately 90% of children with cancer live in low-income and middle-income countries (LMICs), where 5-year survival is lower than 20%. Treatment-related mortality in high-income countries is approximately 3-5%; however, in LMICs, treatment-related mortality has been reported in up to 45% of children with cancer. This study aimed to systematically explore the burden of treatment-related mortality in children with cancer in LMICs and to explore the association between country income level and treatment-related mortality.

A cross sectional study was conducted to determine the prevalence of and risk factors for anemia in infants and children between 6 months to 5 years of age admitted to a tertiary hospital in Botswana. Baseline full blood count of every patient admitted during the study period was assessed to determine if anemia was present.

We describe a retrospective cohort review of pediatric patients with KS treated with paclitaxel in Mbeya, Tanzania, between 1 March 2011 and 31 December 2019. Paclitaxel was given to patients who had KS relapse, a contraindication to bleomycin, vincristine, and doxorubicin (ABV), special circumstances in which a clinician determined that paclitaxel was preferable to ABV, or experienced treatment failure, defined as persistent KS symptoms at the completion of treatment.

Living with HIV confers a risk of developing HIV-associated cancers. To determine the incidence and risk factors for cancer among CLWH, we conducted a nested case-control study of children 0-18 years from 2004-2014 at five centers in four SSA countries.

Treating KS in pregnancy must balance both the well-being of the mother with the health of the fetus, yet data and recommendations on the best treatment approach for KS during pregnancy are limited. Without effective treatment, which can be difficult to obtain in low income countries (LICs), the mother and infant are at risk for poor outcomes.

Background: A major barrier in improving cancer outcomes in Botswana and other low- and middle-income countries is timely access to care. Understanding time to diagnosis of pediatric cancers in Botswana and evaluating factors contributing to delays was necessary to inform interventions.
Methods: A retrospective cohort study of children diagnosed with cancer at Princess Marina Hospital from 2008 to 2015 was performed utilizing the Botswana Pediatric Oncology Database.
There is a striking disparity in survival rates for children in low- and middle-income countries (LMICs) compared with high-income countries (HICs). Many of the contributing factors are preventable, including the comorbidity of malnutrition. There are emerging data that malnutrition, as reflected in body composition changes, impacts survival of cancer.

Currently, there is incomplete information on pediatric cancer incidence, diagnosis distribution, and treatment outcomes in Africa. Since 2007, a pediatric hematology-oncology program has been operating in Botswana through a partnership between the Botswana government, Baylor College of Medicine, and Texas Children's Hospital.

Diagnosing non-jaw mass presentations is challenging with limited pathology resources. We retrospectively analyzed 114 pediatric lymphomas in Lilongwe, Malawi, from December 2011 to June 2013 and compared clinical versus pathology-based diagnoses over two time periods.

Moreover, reported IPM adoption rates by flue-cured tobacco growers remain low, at < 40%, according to NC cooperative extension surveys conducted during the last four years. Previous research has suggested that timing insecticide treatments using currently available ETs can reduce the average number of applications to two or fewer per season.

Botswana, a country of approximately 2 million people in southern Africa, has only 1 pediatric cancer treatment program, based at Princess Marina Hospital (PMH) in the capital of Gaborone. A pediatric cancer recognition training program was developed that reached 50% of the government hospitals in Botswana teaching 362 health care workers how to recognize and refer children with cancer to PMH.
