Abstract
BACKGROUND: Quality health services could improve patient outcomes and prognosis. Gastric cancer care was of great disparity across genders. Disparities within radiotherapy units could impact gastric cancer care, potentially exacerbating gender-based inequalities. METHODS: We retrieved the disease burden data from Global Burden of Disease 2019. A quality of care index was constructed by applying principal component analysis techniques. The disparity of gastric cancer care across genders was described, and the association of access to radiotherapy with gastric cancer care as well as gender disparity was explored. RESULTS: Males receive better quality of gastric cancer care than females, and this gender disparity is widening in middle-low socio-development regions. A positive correlation emerges between the density of radiotherapy facilities and an elevated quality of care, and reduced gender-based disparities. CONCLUSIONS: The association between robust radiotherapy access, improved gastric cancer QCI, and reduced gender-based disparities spotlights the imperative of fortifying radiotherapy infrastructure within areas and populations in greatest need.
