Background:
Published data on childhood and adolescent cancers in northern Ghana is scanty. The aim of this retrospective histopathological study was to identify and describe the relative proportions of childhood and adolescent cancers and the associated clinico-pathological features at the Tamale Teaching Hospital.
Materials And Methods:
The cancers were classified according to the International Classification for Cancer in Children. Data was collected on the demographics and the clinico-pathological characteristics of the various types of cancers, from 1st January 2012 to 31st December, 2021, a 10-year period. The data was analysed using SPSS software (Version 26, Chicago).
Results:
A total of 196 childhood and adolescent cancers were reviewed, with a mean age of 9.5± 5.5 years. Approximately, 51.5% were female, with a younger mean age (years) of 8.4±5.3, compared to 10.6±5.6 for males. Majority (74.0%), were within the 0-14 years age group, (P<0.0001). All the patients presented with swellings and mostly after 6 months of disease onset. The common cancers for the study population were: soft tissue sarcoma (24.2%), primary bone cancer (21.1%), retinoblastoma (17.5%), lymphoma (13.3%), and germ cell tumours (6.7%). For females these were: soft tissue sarcoma (21.0%), retinoblastoma (20.0%), primary bone cancer (19.0%), nephroblastoma (13.0%), and ovarian tumours (12.0%). For males, these were: soft tissue sarcoma (27.7%), bone cancer (23.4%), lymphoma (19.1%), retinoblastoma (14.9%) and head and neck cancer (6.4%). The common soft tissue cancers were: rhabdomyosarcoma (46.8%), and spindle cell sarcoma (NOS) (17.0%). Osteosarcoma (70.7%), and Ewing's sarcoma 6 (14.6%) were the common primary bone cancers. Many (46.4%) of the retinoblastomas were of a high pathological TNM stage III. The optic nerve was involved in 70.6%, with 26.5% margin involvements.
Conclusion:
Childhood and adolescent cancers were common in pediatric age group with late stage at presentation. The common histological subtypes were: soft tissue sarcoma, primary bone cancer and retinoblastoma. There is the need for detection, diagnosis, and prompt oncology care.
