Delivering modern anticancer therapies in low- and middle-income settings: We can be evidence based

SIOP PODC adapted risk stratification and treatment guidelines: Recommendations for acute myeloid leukemia in resource-limited settings

In low- and middle-income countries (LMICs), limited resources, suboptimal risk stratification, and disproportionate patient-to-infrastructure ratio result in low survival of patients with acute myeloid leukemia (AML). A high incidence of relapse, inherent to the biology, renders management arduous. The challenge of treating AML in LMICs is of balancing the intensity of myelosuppressive chemotherapy, which appears necessary for cure, with available supportive care, which influences treatment-related mortality. The recommendations outlined in this paper are based on published evidence and expert opinion. The principle of this adapted protocol is to tailor treatment to available resources, reduce preventable toxic death, and direct limited resources toward those children who are most likely to be cured.

A single assessment of methotrexate levels at 42 hours permits safe administration and early discharge in children with lymphoblastic lymphoma and leukemia receiving high-dose methotrexate

High-dose methotrexate (HDMTX) is an important component of treatment in pediatric acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LL). Optimal rescue therapy is essential for the safe administration of HDMTX. A cost-effective strategy that does not compromise safety is necessary for low- and middle-income countries. Consecutive admissions for HDMTX in children with ALL and LL over 12 months were analyzed. The dose of HDMTX was 3 g/m² in B-ALL and B-LL and 5 g/m² in T-ALL and T-LL. A methotrexate level was measured at 42 hours of starting HDMTX infusion (T42-MTX). Three doses of folinic acid at T42, T48, and T54 and alkalinized hydration till T54 were administered if T42-MTX <1 µM. A total of 282 cycles of HDMTX that were administered in 71 patients were analyzed. T42-MTX was <1 µM in 266 (94.3%) cycles. T42-MTX was ≥1 µM in 12% and 3% of cycles of HDMTX administered at a dose of 5 g/m2 and 3 g/m2, respectively (p = .074). The median duration of hospitalization for HDM was three days and did not differ with the dose of HDMTX administered (p = .427). Mucositis, delayed recovery of blood counts, and hospitalization for reversible toxicity occurred after 21 (7.4%), 28 (9.9%), and 19 (6.7%) cycles of HDMTX, respectively. Mucositis was greater following the administration of 5 g/m² of HDMTX. A single T42-MTX measurement permits the safe administration of HDMTX and an expedited discharge from the hospital within three days in more than 90% of children with ALL/LL.

Highlights from the 13th African Continental Meeting of the International Society of Paediatric Oncology (SIOP), 6-9 March 2019, Cairo, Egypt

The 13th African continental meeting of the international society of paediatric oncology, held on 6-9 March 2019 in Cairo, was organised in collaboration with the Children Cancer Hospital (57357) in Egypt and the global parents' organisation (Childhood Cancer International) and supported by a large international faculty. With 629 delegates from 37 countries (24 African), this was the largest forum of healthcare professionals focused on children and young people with cancer in Africa to showcase advances and discuss further improvements. Three targeted workshops, on nursing care, pharmacy and nutrition, attracted large numbers and catalysed new collaborative initiatives in supportive care studies, extended roles for pharmacists in quality control and care delivery and addressed malnutrition concurrently with cancer treatment. The Collaborative Wilms Tumour Africa Project, open in seven sub-Saharan countries, and the trials in Burkitt's lymphoma reported encouraging outcomes with further initiatives in supportive care (the supportive care for children with cancer in Africa project). While acknowledging deficits in radiotherapy provision, available in only 23 of 52 African countries, centres with facilities reported their technical advances that benefit patients. Of great importance for children with brain tumours, who are underdiagnosed in Africa, was the first announcement of African paediatric neuro-oncology society, whose 63 current members aim to tackle the shortage of neurosurgeons through training fellowships, workshops and a dedicated conference. The congress provided the opportunity to discuss how African countries will work with the WHO global initiative aiming to improve childhood cancer survival to 60% in all countries by 2030. This conference report is dedicated to the three Kenyan delegates who died tragically on the Ethiopian Airlines flight ET302 on their way home, full of new ideas and pride in what they had achieved so far. All those who heard their presentations are determined to continue their excellent work to improve cancer care for children in Africa.

Science and health for all children with cancer

Each year ~429,000 children and adolescents aged 0 to 19 years are expected to develop cancer. Five-year survival rates exceed 80% for the 45,000 children with cancer in high-income countries (HICs) but are less than 30% for the 384,000 children in lower-middle-income countries (LMICs). Improved survival rates in HICs have been achieved through multidisciplinary care and research, with treatment regimens using mostly generic medicines and optimized risk stratification. Children’s outcomes in LMICs can be improved through global collaborative partnerships that help local leaders adapt effective treatments to local resources and clinical needs, as well as address common problems such as delayed diagnosis and treatment abandonment. Together, these approaches may bring within reach the global survival target recently set by the World Health Organization: 60% survival for all children with cancer by 2030.
