Objective. Chest radiography films used in lung cancer screening by the Saga General Health Association are read by 2 groups consisting of 2 examines per group and compared individually. Positive predictive value and the number of individuals having further examinations are higher, the number of individuals requiring further examinations is lower, and detection rate is the same as or higher than the national average. Quality was adequately controlled. To improve quality, we started case conferences for screening-detected lung cancer attended by all examines in 1999. Methods. Reading is to be standardized by returning and jointly discussing information to examines. Results. The detection rate exceeded the national average and the number of individuals requiring further examination increased. Positive predictive value declined but is still much better than the average. The number of individuals seeking further examination is rising. Conclusion. Screening-detected lung cancer case conferences appear to be vital to ensuring quality control in reading radiography films.
