Objective. The statistics of lung cancer incidence rates, treatment results, and survival rates in Japan are well documented; however, the subject of each statistics is not the same. In Niigata Prefecture, it is possible to obtain the above mentioned statistics based on similar subjects. For this reason, we reviewed the statistics of lung cancer in Niigata Prefecture. Material and Methods. We analyzed the data of the Japanese Association of Cancer Registries of Niigata Prefecture and the Niigata-Prefecture Surgical Resection of Lung Cancer Cohort Study, and reviewed the changes in the statistics of lung cancer in Niigata Prefecture from 1991. Results. In Niigata Prefecture, lung cancer was the leading cause of death from cancer, and the mortality rate was consistent with the national rate. The 5-year survival rate of lung cancer patients improved over time, and was estimated to be 29.0% in 2000 and 2004. The main cause of the improvement was the increase in the detection rate of early-stage small-sized lung cancers and their successful treatment by surgical resection. Conclusion. The survival rate of lung cancer patients in Niigata Prefecture improved over time with the increase in the detection rate of early-stage small-sized lung cancers.
