 note = {application/pdf, 論文(Article), Uterine cervical cancer screening using the Bethesda system was put into use in Niigata Prefecture in 2010. However, the effectiveness of the screening using the Bethesda system has not been well evaluated. We aimed to compare the results of smears diagnosed using the Bethesda system in 2010 with the results of smears diagnosed using the Nichibo classification from 1995 through 2009. A total of 337,029 women were screened for cancer. The diagnoses obtained using the Bethesda system (18,449 examinees) were compared with those obtained using the Nichibo classification at the period of 15 years (318,580 examinees). The rate of abnormalities and the detection rate of dysplasia were displayed significant difference between Nichibo classification and Bethesda system (p<0.05). However, no significant difference was found in the cancer detection rate between the two classification methods. This finding shows that the Bethesda system is useful for the early detection of dysplasia such as precursor lesions of the uterus and in early treatment.},
