Aims
We describe the absolute and per capita numbers of megavoltage radiotherapy machines (MVMs) in Western Africa from 1969 to 2019.
Materials and methods
Western Africa was defined in accordance with the United Nations' delineation and inclusive of 16 countries. A literature search for publications detailing the number of cobalt-60 machines (COs...
Aims
Childhood cancer survival is suboptimal in most low- and middle-income countries (LMICs). Radiotherapy plays a significant role in the standard care of many patients. To assess the current status of paediatric radiotherapy, the International Atomic Energy Agency (IAEA) undertook a global survey and a review of practice in eight leading treatme...
Topical Overview and Conclusions of an International Conference
Purpose or Objective: One of the challenges in modern radiotherapy (RT) is variability in contouring of target volumes (TVs) and organs at risk (OARs). Interactive online teaching has shown immediate improvement of homogeneity of delineation but the long-term effect is unknown. The aim of the present multicenter study was to evaluate the short- and...

... 14 A contemporary review of the availability of megavoltage machines in West Africa shows an exponential increase in capacity, particularly in the last decade. 17 The increase was seen across the region in multiple countries in tandem with the period of an international campaign to increase access to radiotherapy through high level organizations such as the International Atomic Energy Agency, the Union for International Cancer Control and WHO. 15 ...

... Provision of sustainable and effective cancer services in any country, to any population of patients, requires a clear understanding of the national treatment healthcare infrastructure, financial support and reimbursement mechanisms, distribution of services and expertise, and access to clinical trials [9][10][11]. Paediatric oncology provision in eastern European countries have been previously described, identifying discrepancies in outcomes, variations in access to specialised services for children and adolescents, and unequal use and distribution of expertise [3,6,[12][13][14]. ...

... However, H&N nodal levels are no simple anatomical structures like organs at risk (OAR) or even primary tumors and lymph node metastases. Instead, H&N nodal levels are complex anatomical compartments defined and separated by a multitude of anatomical landmarks requiring a lot of training time and experience for correct manual delineation by clinical experts (1,9). Earlier publications focused on atlas-based autosegmentation, which led to some considerable improvements. ...

... The longer-term impact on contouring proficiency and performance is therefore uncertain. This has been built into a multicenter prospective study performed by the European Society for Radiotherapy and Oncology, with the International Atomic Energy Agency [45]. Finally, the controlled nature of the impact assessment means that a participant's proficiency in daily clinical practice is uncertain. ...
