Abstract
In 2001, biennial breast cancer screening with mammography was started in Koriyama City for women aged 40 years or over. The screening involved both physical examination, including inspection and palpation, and mammography performed separately. Women with abnormal findings on physical examination were recalled, while those without such findings underwent medio-lateral oblique projection mammography. There were a total of 15, 246 responders during the three-year period 2001-2003.
The recall rate after physical examination was 3.1% and breast cancer was detected in 25 women (0.16%). For 13, 310 women who underwent mammography, the recall rate was 3.9% and 25 breast cancers (0.18%) were detected. Combining these two subgroups, the overall recall rate was 6.5%, the cancer detection rate was 0.33%, the ratio of cancers detected among women who were asked to attend for a recall examination was 5.0%, and the ratio of cancers detected among women who underwent a recall examination was 5.6%. Early cancers detected at Stage 0 or 1 comprised 32 (64%), and lymph node metastasis was positive in 12 women (24%).
Thus the results of our screening reached satisfactory levels in terms of the five items proposed by the Breast Imaging Reporting and Data System of the American Radiology Association. In order to further increase the quality of breast cancer screening, proper determination of categories at mammography reading and standardization of recall examination techniques, including histopathological study, are required.
