Background/Purpose Stage at diagnosis is an important metric in treatment and prognosis of cancer, and also in planning and evaluation of cancer control. In sub-Saharan Africa (SSA), for the latter, the only data source is the population-based cancer registry (PBCR). For childhood cancers, the “Toronto Staging Guidelines” have been developed to facilitate abstraction of stage by cancer registry personnel. Although the feasibility of staging using this system has been shown, there is limited information on the accuracy of staging. Methods A panel of case records of 6 common childhood cancers was established. 51 cancer registrars from 20 SSA countries staged these records, using Tier 1 of the Toronto guidelines. The stage that they assigned was compared with that decided by two expert clinicians. Results The registrars assigned the correct stage for 53-83% of cases (71% overall), with the lowest values for acute lymphocytic leukaemia (ALL), retinoblastoma and non Hodgkin lymphoma (NHL), and the highest for osteosarcoma (81%) and Wilms tumour (83%). For ALL and NHL, many unstageable cases were mis-staged, probably due to confusion over the rules for dealing with missing data; for the cases with adequate information, accuracy was 72-73%. Some confusion was observed over the precise definition of three stage levels of retinoblastomas. Conclusions A single training in staging resulted in an accuracy, for solid tumours, that was not much inferior to what has been observed in high income settings. Nevertheless, some lessons were learned on how to improve both the guidelines, and the training course.

Background Childhood cancer is the sixth leading cause of global cancer burden. Indeed, 90% of childhood cancer cases occur in low-middle-income countries (LMICs), where mortality can be 4-5 times higher than in high income settings. In addition, many LMICs lack data on pediatric oncology for policy development and resource prioritization. In this paper, we describe the state of pediatric cancer care and treatment in Cameroon. Procedure We conducted cross-sectional survey in July 2020, which enabled us to collect data from two hospitals providing pediatric oncology services in Cameroon. We collected data on service availability, human resource capacity, frequent cancer types, treatment dropout, primary reasons for drop out, disclosure of status, and management of oncology data. Result The surveyed hospitals offered both pediatric chemotherapy and palliative care services; however, none offered nuclear medicine or radiotherapy services. In terms of workforce, human resources were grossly lacking in both hospitals. The available ones include one pediatric hemato-oncologist, one medical oncologist, one resident pediatric oncologist, one pediatric surgeon, and 14 oncology nurses and about 40% (18/45) of have received specialty training in oncology. The commonest childhood cancer managed in these facilities, was Burkitt lymphoma, (39, 23%). About 30% of children on chemotherapy abandoned their treatment, primarily due to lack of funds to continue with treatment sessions. In both settings, the capacity to diagnose cancer and provide counselling was limited. In addition, the tools to capture and transmit data varied by facility, resulting to different data set being generated. Furthermore, both facilities, had no schedule and timelines for data reporting. Conclusions Our results suggest that several factors negatively impact proper cancer care and treatment of pediatric Cancers in Cameroon. These include, inadequate human resource capacity, a high proportion of dropouts from chemotherapy due to high cost, and lack of harmonized data collection and reporting tools and systems. Systematically addressing these factors could contribute to improving treatment outcomes for pediatric cancer patients in Cameroon.

BACKGROUND The aim of this study was to investigate the progress made with pediatric oncology care in Cameroon from 2000 to 2020. METHOD A literature search was conducted for published articles on childhood cancer in Cameroon and relevant documents and conference abstracts were reviewed. The articles were analysed under eight themes: covering detection, diagnosis, management and program development. RESULTS Forty publications were analysed. Cancer diagnosis was achieved with cytology, histology and simple imaging. Management for common and curable cancers was with use of modified treatment regimens for low- and middle- income settings. There was good collaboration between the pediatric oncology professionals nationally and international partners. Advocacy led to the support of the Ministry of Health with pediatric oncology specific priority actions in the latest national cancer control plan. CONCLUSION Commitment of childhood cancer specialists, non-governmental organizations, and the government can lead to successful childhood cancer management in a low-income country.
