Abstract

In 2015, the United Nations proposed "The 2030 Agenda for Sustainable Development" goals, which envision reducing premature mortality from noncommunicable diseases by one third by 2030. Because >50% of patients with cancer require radiation therapy (RT), the existing gaps in RT infrastructure in low- and middle-income countries (LMICs) and additional requirements by 2030 were examined. Cost-effective strategies to address this challenge were explored. Public domain databases of the United Nation organizations were accessed. RT requirements for 2030 were estimated according to the International Atomic Energy Agency recommendations. To explore a feasible cost-effective solution, a teleradiotherapy network (TRTNet) was conceived with 4 to 8 primary RT centers (PRTCs) (each with 1 teletherapy unit, US$2.05 million) linked to a secondary RT center (SRTC; 2 teletherapy units and 1 brachytherapy unit, US$5.05 million). Of the 137 LMICs, 51 (37.3%) presently lack RT facilities. The remaining 86 LMICs have 5084 teletherapy units (gap: -7741) and thus a mean access to RT of 33%. By 2030, an additional 12,133 teletherapy units would be required for 14.2 million patients with cancer. A TRTNet linked 4 to 8 PRTCs with 1 SRTC could yield a return of investment (ROI) between -181.1% and 757.6% depending on the TRTNet configuration, 2-year survival, gross national income per capita, and employment-population ratio of the individual LMICs. Sixty-five (47.4%) of these could be expected to attain a positive ROI (7.1% to 757.6%) with a 2-year survival of 50% and a TRTNet configuration of 1 SRTC and 8 PRTCs. Optimized TRTNets through resource sharing could be a cost-effective and financially viable option to create RT infrastructure and facilitate capacity building toward realizing the 2030 Agenda for Sustainable Development goals in most LMICs. Low-income countries and some LMICs not expected to gain positive ROI should be considered for external financial assistance.
