Randomized controlled trials (RCTs) are the cornerstone of delivering sustained improvements in cancer outcome. To inform radiation therapy research policy and prioritization, we analyze the radiation therapy RCT landscape including comparison with trials of systemic therapies over the same period, with a specific focus on funding and disparities across income settings. This retrospective cohort study identified all phase 3 RCTs evaluating anticancer therapies published from 2014 to 2017. RCTs were classified according to anticancer modality and country of origin. Descriptive statistics were used to compare key characteristics of radiation therapy RCT studies according to study design characteristics, tumor types evaluated, types of intervention appraised, treatment intent and main funding sources. The study cohort included 694 RCTs of which 64 were radiation therapy RCTs (9%) compared with 601 systemic therapy RCTs (87%). Among all radiation therapy RCTs, 47% of them focused on 2 areas of evaluation: (1) combining radiation therapy with systemic agents (25%) and (2) changes in dose fractionation (22%). The most common cancers studied were head and neck (22%), lung (22%), and breast (14%), with cervical cancer trials representing only 3% of the cohort. Among the radiation therapy RCTs, 33% of them met their primary endpoint, and 62% assessed interventions in the curative setting compared with 31% in systemic therapy RCTs. For their country locations, 77% of radiation therapy RCTs took place in high-income countries, 13% in low-and-middle-income countries, and 11% in both high-income and low-and-middle-income countries. For funding, 17% of radiation therapy RCTs received funding from industry compared with 79% of systemic therapy RCTs. This study highlights the need for greater investment in radiation therapy RCTs and the need to look at the disparities in conducting RCTs globally. The study emphases the urgent need for more capacity building for cancer clinical trials in low-and-middle-income countries and more sustainable funding sources.

Disparities in cancer research persist around the world. This is especially true in global health research, where high-income countries (HICs) continue to set global health priorities further creating several imbalances in how research is conducted in low and middle-income countries (LMICs). Cancer research disparities in Africa can be attributed to a vicious cycle of challenges in the research ecosystem ranging from who funds research, where research is conducted, who conducts it, what type of research is conducted and where and how it is disseminated. For example, the funding chasm between HICs and LMICs contributes to inequities and parachutism in cancer research. Breaking the current cancer research model necessitates a thorough examination of why current practices and norms exist and the identification of actionable ways to improve them. The cancer research agenda in Africa should be appropriate for the African nations and continent. Empowering African researchers and ensuring local autonomy are two critical steps in moving cancer research towards this new paradigm.

PURPOSE: The COVID-19 pandemic has disrupted cancer care globally. There are limited data of its impact in Africa. This study aims to characterize COVID-19 response strategies and impact of COVID-19 on cancer care and explore misconceptions in Africa. METHODS: We conducted a web-based cross-sectional survey of oncology providers in Africa between June and August 2020. Descriptive statistics and comparative analysis by income groups were performed. RESULTS: One hundred twenty-two participants initiated the survey, of which 79 respondents from 18 African countries contributed data. Ninety-four percent (66 of 70) reported country mitigation and suppression strategies, similar across income groups. Unique strategies included courier service and drones for delivery of cancer medications (9 of 70 and 6 of 70, respectively). Most cancer centers remained open, but > 75% providers reported a decrease in patient volume. Not previously reported is the fear of infectivity leading to staff shortages and decrease in patient volumes. Approximately one third reported modifications of all cancer treatment modalities, resulting in treatment delays. A majority of participants reported ≤ 25 confirmed cases (44 of 68, 64%) and ≤ 5 deaths because of COVID-19 (26 of 45, 58%) among patients with cancer. Common misconceptions were that Africans were less susceptible to the virus (53 of 70, 75.7%) and decreased transmission of the virus in the African heat (44 of 70, 62.9%). CONCLUSION: Few COVID-19 cases and deaths were reported among patients with cancer. However, disruptions and delays in cancer care because of the pandemic were noted. The pandemic has inspired tailored innovative solutions in clinical care delivery for patients with cancer, which may serve as a blueprint for expanding care and preparing for future pandemics. Ongoing public education should address COVID-19 misconceptions. The results may not be generalizable to the entire African continent because of the small sample size.

PURPOSE: Choosing Wisely Africa (CWA) builds on Choosing Wisely (CW) in the United States, Canada, and India and aims to identify low-value, unnecessary, or harmful cancer practices that are frequently used on the African continent. The aim of this work was to use physicians and patient advocates to identify a short list of low-value practices that are frequently used in African low- and middle-income countries. METHODS: The CWA Task Force was convened by the African Organization for Research and Training in Cancer and included representatives from surgical, medical, and radiation oncology, the private and public sectors, and patient advocacy groups. Consensus was built through a modified Delphi process, shortening a long list of practices to a short list, and then to a final list. A voting threshold of ≥ 60% was used to include an individual practice on the short list. A consensus was reached after a series of teleconferences and voting processes. RESULTS: Of the 10 practices on the final list, one is a new suggestion and 9 are revisions or adaptations of practices from previous CW campaign lists. One item relates to palliative care, 8 concern treatment, and one relates to surveillance. CONCLUSION: The CWA initiative has identified 10 low-value, common interventions in Africa’s cancer practice. The success of this campaign will be measured by how the recommendations are implemented across sub-Saharan Africa and whether this improves the delivery of high-quality cancer care.

Existing literature has described the projected increase in cancer incidence and the associated deficiencies in the cancer workforce. However, there is currently a lack of research into the necessary policy and planning steps that can be taken to mitigate this issue. Herein, we review current literature in this space and highlight the importance of implementing oncology workforce registries. We propose the establishment of cancer workforce registries using the WHO Minimum Data Set for Health Workforce Registry by adapting the data set to suit the multidisciplinary nature of the cancer workforce. The cancer workforce registry will track the trends of the workforce, so that evidence can drive decisions at the policy level. The oncology community needs to develop and optimize methods to collect information for these registries. National cancer societies are likely to continue to lead such efforts, but ministries of health, licensing bodies, and academic institutions should contribute and collaborate.
