抄録

Guidelines for breast cancer screening using mammography in women aged 50 years and over were announced by the Ministry of Health and Welfare in 2000. We tested the effectiveness of mammography for breast cancer screening in a study funded by the Ministry between 1998 and 1999, through the Sendai City Medical Association. The subjects were 2, 285 women aged between 50 and 69. Firstly, MLO imaging was performed on both breasts. The patient then took the mammograms to an individually chosen private practice for reading and a clinical breast examination. Finally, the mammograms were collected in the screening center and read by specialists in mammography. <BR>Overall recall rate was 4.5% ; the rate from clinical breast examination was 1.0%. Seven breast cancers were detected in 2, 285 subjects by the specialists with the doctors in private practice detecting four of the cases. Six of the seven cancers were node negative. Five months after screening, one woman was diagnosed as having breast cancer. The sensitivity, specificity and positive predictive values of the screening were 87.5%, 95.8% and 6.8%, respectively. <BR>The introduction of mammography for breast cancer screening in private practice is likely to rise and contribute to a higher level of breast cancer screening nationwide.
