ABSTRACT
PURPOSE:
To investigate regional disparities in lung cancer surgery in Japan.METHODS:
The annual incidence of lung cancer, lung cancer surgery, and the number of board-certified thoracic surgeons in Japan during 2014-2019 were investigated using a national open database. Lung cancer surgeries were categorized by procedure (wedge resection, segmentectomy, lobectomy, pneumonectomy) and approach (open, thoracoscopic). Disparities in 47 prefectures and urban-rural disparities during 2017-2019 were evaluated using the Gini coefficient and an unpaired t-test. Correlation was assessed using Pearson's correlation method.RESULTS:
The national annual average incidences of lung cancer and lung cancer surgery were 121,106 and 50,959, respectively, in 2014-2019. The use of the thoracoscopic approach increased over time in all procedures, except pneumonectomies. The Gini coefficients of lung cancer, thoracoscopic surgery, and board-certified thoracic surgeons indicated low inequality across prefectures; however, those of open surgery indicated high inequality. Open surgery was more common in urban areas than in rural areas. The number of thoracoscopic surgeries and board-certified thoracic surgeons by prefecture were moderately correlated.CONCLUSION:
The thoracoscopic approach is becoming more common in lung cancer surgery, with little inter-prefectural regional disparity in the incidence of lung cancer, thoracoscopic surgeries, or the number of board-certified thoracic surgeons.
