To compare the cost and accuracy of upper gastrointestinal (GI) X-ray and upper endoscopy for diagnosis of gastric cancer using data from the 2002-2004 Korean National Cancer Screening Program (NCSP).
The study population included 1,503,646 participants in the 2002-2004 stomach cancer screening program who underwent upper GI X-ray or endoscopy. The accuracy of screening was defined as the probability of detecting gastric cancer. We calculated the probability by merging data from the NCSP and the Korea Central Cancer Registry. We estimated the direct costs of the medical examination and the tests for upper GI X-ray, upper endoscopy, and biopsy.
The probability of detecting gastric cancer via upper endoscopy was 2.9-fold higher than via upper GI X-ray. The unit costs of screening using upper GI X-ray and upper endoscopy were $32.67 and $34.89, respectively. In 2008, the estimated cost of identifying one case of gastric cancer was $53,094.64 using upper GI X-ray and $16,900.43 using upper endoscopy. The cost to detect one case of gastric cancer was the same for upper GI X-ray and upper endoscopy at a cost ratio of 1:3.7.
Upper endoscopy is slightly more costly to perform, but the cost to detect one case of gastric cancer is lower.
利用韩国 2002-2004 年国家癌症筛查计划（NCSP）的数据，比较上消化道（GI）X 射线和上内窥镜检查诊断胃癌的成本和准确性。
本研究的人群包括 2002-2004 年胃癌筛查计划中接受上消化道 X 射线或内窥镜检查的 1,503,646 名参与者。筛查的准确性定义为检测胃癌的概率。我们通过合并 NCSP 和韩国中央癌症登记处的数据来计算概率。我们估计了上消化道 X 射线、上内窥镜检查和活检的医疗检查和测试的直接成本。
通过内窥镜检查检测胃癌的概率是通过上消化道 X 射线的 2.9 倍。使用上消化道 X 射线和上内窥镜检查进行筛查的单位成本分别为 32.67 美元和 34.89 美元。在 2008 年，使用上消化道 X 射线和上内窥镜检查分别识别一例胃癌的估计成本为 53,094.64 美元和 16,900.43 美元。上消化道 X 射线和上内窥镜检查检测一例胃癌的成本相同，成本比为 1:3.7。
上内窥镜检查的执行成本略高，但检测一例胃癌的成本较低。
