Abstract

Abstract: Background: Pacific Island Countries and Territories (PICTs) have experienced an increase in cancer burden in the recent years. There is need for major investments in the cancer treatment facilities including radiotherapy (RT). Aims: This study aimed to provide a quantitative estimation of the effect of establishing new RT facilities on patient access through Geographic Information System (GIS) modelling of population density and service availability to assess the best location for a new RT centre when there are multiple competing locations. Methods: Methods involved cancer epidemiological data collection and assessing RT demand (proportion needing RT) in 2040, assessment of current RT facilities meeting the demand, GIS‐based assessment of minimal travel distance in relation to RT demand and scenario‐based location planning with adoption of the principles of efficiency, availability and equity for establishment of suitability of new RT facilities. Results: In 2040, three highest new cancer case projections are for Papua New Guinea (PNG) (22662), Fiji (2058) and New Caledonia (2037). Twenty‐nine megavoltage machines (MVMs) are needed to meet adequate RT demand with three existing in New Caledonia, Guam and French Polynesia meeting 2–6% demand. PNG with highest RT demand of 68% and Fiji with second highest (6%) demand are found as the choice venues for maximum accessibility of cancer population within the PICTs. Conclusion: The travel distance‐based GIS modelling estimation of establishment of new RT facilities will provide useful information for planning of RT services in the PICTS with improved patient outcome. Abstract : Our study provided an estimation of the effect of establishing new radiotherapy facilities on patient accessibility in Pacific Island Countries and Territories (PICTs). Our unique modelling approach of spatial distribution of population density versus service availability would lead to improved patient access and cancer outcomes in the region.
