Cancer control collaborations between China and African countries.

Over the past decade, China has emerged as Africa's largest trade partner and source of foreign direct investment, with public health ranked as a top priority in China-Africa collaborations. During the same period, cancer has emerged as a leading cause of death in Africa, with more than 700 000 deaths per year and projections of more than 1 million deaths per year by 2030. In this Review, we explore the effects of increasing China-Africa collaborations on cancer control in Africa. We review the published literature on health-care assistance, research, education and training, and infrastructure and present the results of an institutional review board-approved survey of African oncology health-care professionals and institutional leaders that assessed their perception of the effects of China-Africa collaborations. From peer-reviewed articles and grey literature, we found that the number of China-Africa collaborations have grown substantially over the past decade in different areas, especially in patient care and infrastructure. Research publications have also surged in quantity in the past decade compared with previous years. However, the survey results suggest research collaborations remain infrequent and that medical professionals in African cancer centres rarely participate in direct research collaborations with Chinese institutions. The Review also highlights the challenges and benefits of increasing China-Africa collaborations. Challenges include insufficient monitoring and evaluation of the projects in Africa and poor coordination and alignment of the various initiatives. The benefits of these collaborations for Africa include improved health outcomes, strengthened health systems, and socioeconomic development. Benefits are also apparent for China, such as securing energy and resource supplies, expanded trade and investment opportunities, and improved diplomatic relations. Overall, China-Africa collaborations are increasing and having a substantial effect in both China and the African continent. Recommendations to minimise the challenges and maximise the benefits for more positive consequences on cancer control in Africa are discussed.

Increasing pediatric radiation oncology capacity in sub-saharan Africa using technology: a pilot of a pediatric radiation oncology virtual training course.

BACKGROUND: The shortage of skilled healthcare professionals in pediatric oncology and the limited access to training programs remain significant challenges in Nigeria and sub-Saharan Africa. The the Pediatric Radiation Oncology (Virtual) Course, 'PedROC' project aims to contribute to improving pediatric cancer outcomes in Nigeria by increasing the capacity of radiation oncology professionals. To address the gap in access to pediatric radiation oncology professional development, the PedROC project was created, harnessing technology to improve radiation oncology training via a curriculum delivered through web-conferencing. This study aimed to evaluate the effectiveness of the PedROC pilot in enhancing the capacity, confidence, and skill of radiation oncologists in decision-making, prescribing, and treatment planning of radiotherapy for children diagnosed with cancer. METHODS: A multidisciplinary faculty of specialists in radiation oncology, pediatric oncology, oncology nursing, radiation therapy technology, and medical physics collaborated to identify the key learning needs in pediatric radiation oncology in the country. The team collaborated to develop a comprehensive curriculum covering the most common pediatric cancers in sub-Saharan Africa for the training program. The training course was conducted over two days, delivering twenty-four half-hour sessions for a total of 12 h, from July 31 to August 01, 2021. RESULTS: Analysis of pre and post - training surveys showed a significant increase in self-reported confidence measures across all domains among radiation oncologists. The program successfully improved participants' knowledge and confidence levels in managing common pediatric cancers using radiotherapy, particularly addressing radiotherapy-specific issues such as appropriate dose, target volume delineation, treatment planning, dose constraints, and plan evaluation. CONCLUSION: The PedROC pilot showed the efficacy of this model in enhancing the capacity and confidence of radiation oncology professionals involved in the treatment of pediatric cancer. The findings indicate that technology holds significant potential to increase pediatric radiation oncology capacity in Africa, ensuring improved access to proper treatment and ultimately improving pediatric cancer outcomes.

Feasibility and Safety of Implementing Volumetric Arc Therapy (VMAT) for Pediatric Craniospinal Irradiation in a Low-Middle-Income Region: The Nigerian Experience.

Purpose: Volumetric modulated arc therapy (VMAT) is a relatively new treatment technique in sub-Saharan Africa. Although craniospinal irradiation (CSI) in the pediatric population has been practiced in Nigeria for many years, the use of VMAT to deliver this treatment is previously undocumented. We reviewed the first set of patients to undergo CSI at a cancer center in Nigeria, detailing the treatment technique, the progress experienced, dose statistics achieved, treatment toxicities, and cancer outcomes to date. Methods and Materials: This was a prospective case series of 5 children with histologically diagnosed cancers requiring CSI whose parents consented to the study. They were recruited at evaluation and followed through the process of their therapy. Toxicity was monitored at weekly review appointments using the Common Terminology Criteria for Adverse Events version 5.0. Follow-up of the children will continue in the long-term effects clinic. Results: Five patients with a median age of 6 were recruited. Diagnoses were intracranial germ cell tumor (n = 2), medulloblastoma (n = 1), pineoblastoma (n = 1), and ependymoma (n = 1). For all patients, a dose of 36.0 Gy in 1.8 Gy daily fractions was prescribed to the entire neuraxis. A subsequent boost of 18 Gy (n = 4) to 19.8 Gy (n = 1) in 10 daily fractions to the primary tumor bed (n = 2) and posterior fossa (n = 2) was delivered. Four patients had chemotherapy before, during, or after radiation therapy. No patient experienced grade 3 or greater toxicity. Conclusions: Our results indicate great progress has been made in the delivery of CSI in Nigeria, demonstrating tolerable acute side effects using VMAT. This series suggests the feasibility of implementing VMAT technology in low- or middle-income countries. Additional follow-up will be needed to determine whether survival rates and chronic toxicity rates are similar to those reported in the literature.

The Landscape of Pediatric Radiation Oncology in Nigeria.

Radiation therapy (RT) is an essential part of the multidisciplinary treatment of pediatric cancer. Over the past five decades, significant advances have been made in the delivery of RT, with better dose delivery to disease targets while minimizing exposure to nearby organs at risk. These advances have led to improved treatment outcomes, increased survival, and reduced treatment-related toxicities. Advanced treatment techniques, however, require significant investment in infrastructural and personnel resources. This review documents what is currently available regarding expertise and infrastructure for pediatric radiation oncology practice in Nigeria. It was performed to serve as a foundation for the creation and design of tailored solutions (initiatives and policies) to increase pediatric radiation availability, accessibility, and equity in Nigeria and ultimately improve pediatric cancer treatment outcomes in the region.

Challenges with medical education in Nigeria in the COVID-19 era.

On March 20th 2020 the Federal Government of Nigeria ordered the closure of all educational institutions, this was inclusive of all medical schools in the country. During the initial phases of this closure, most institutions were at a loss on how to proceed with learning as universities in Nigeria use mainly the didactic lecturing model. As the lockdown progressed it became imperative to the institutions to set up e-learning media for continued instruction of students. It was found that in the institutions with e-learning facilities, the preclinical years remained mostly unaffected by the closure of medical schools due to the COVID-19 pandemic, while all institutions came to a standstill as regards providing a suitable alternative for clinical exposure. This therein has caused loss of valuable time and a change in the calendar of the school year, making it uncertain as to when the next set of qualified medical professionals will emerge in Nigeria. In this essay, we take a look at medical education in Nigeria, its challenges and progression in the COVID-19 era. We also take a look at the effect of the pandemic on learning and the subsequent interventions introduced to mitigate it.
