A prospective registry study of the epidemiology and management of childhood cancer in the Gambia-The first year experience.

Background and Aim

Globally, over 180,000 children develop cancers yearly, with about 80% residing in low- or middle-income countries where cancer-associated mortality is also high. In The Gambia, cumulative incidence rate of 27.6 childhood cancers/million population was reported between 2002 and 2011. The current study appraised newly-established pediatric oncological services in The Gambia.

Methods

In this prospective registry study, children with cancer who presented at the pediatric units, Edward Francis Small Teaching Hospital, Banjul, between November 2022 and October 2023 were assessed. Data on sociodemographic variables, mode of admission and presentation, tumor type, diagnostic methods, and challenges such as laboratory support, treatment, use of blood/blood products; and eventual outcome were analyzed.

Results

The median (interquartile range, IQR) age at presentation of the 44 children was 36.0 (22.3-117.0) months. Wilms tumor was the most common tumor 12 (27.3%); followed by leukemia 11 (25.0%); germ cell tumor 8 (18.2%); lymphoma 6 (13.6%); retinoblastoma 4 (9.1%); rhabdomyosarcoma 2 (4.5%) and one central nervous system tumor (2.3%). The median(IQR) duration of symptoms before presentation was 48 (21-90) days, presentation to diagnosis 7.5 (3-20.8) days, and first symptom to diagnosis 62.5 (32-126.8) days. Treatment refusal and abandonment rates were 20.5% and 13.6%, respectively. Families of 93.8% of children could not procure cytotoxic drugs due to nonavailability, high cost, or both. Adequate laboratory monitoring was only available in 6.8%, and none had platelet concentrate transfusion or radiotherapy. The nine (20.5%) who completed treatment are currently being followed up, 10(22.7%) are still receiving chemotherapy, while 2(4.5%) were referred. Eight (18.2%) died, predominantly from metastasis (75%) and severe drug toxicities (25%).

Conclusion

Late presentation and diagnosis, poverty, unavailability of drugs, suboptimal or lack of laboratory testing, blood product, adjuvant medications, and psychosocial supports contributed to high treatment refusal, abandonment, and mortality. These daunting challenges can be ameliorated with regular community sensitization, frequent cancer auditing, and strong political will.
