With the cooperation of the Non-Profit Organization Japan Clinical Research Support Unit (J-CRSU) and the Public Health Research Foundation, we have moved to the new system by the web registration from 2004. In 2006, the number of the registry for institutions was 352 and cases were 22,005. The number of institutions in this prognostic study was 134 and cases were 8788, with 39.9 %. An assessment of 5-year prognosis for cases registered in 2006 has been carried out, and here we report the results thanks to a number of efforts and cooperation. We believe that it is necessary to further promote the registry for contributions to improving breast cancer care and prognosis. Background characteristics of the patients are summarized in Table 1.
