| Research Abstract |
We estimated the cure fraction and median survival time for uncured cancer patients and evaluated cancer care by examining these trends using population-based cancer registry data. Both cure fraction and survival time for esophageal, gallbladder and lung cancer patients improved during the study period. This indicated improvements in diagnostic and treatment techniques for those cancer sites. The cure fraction for liver cancer patients was stable, while the median survival time for uncured patients was prolonged significantly. Improvement of cure fraction without prolongation of survival time for prostate cancer patients suggests the possibility of overdiagnosis.
