Results
A. Study Results
1. Standardization and propagation of breast cancer screening with ultrasonography:
We formulated "Guidelines for Ultrasonography in Breast Cancer Screening" (Japanese and English versions) in 2007. Further, we developed a breast ultrasonography workshop in line with the Guidelines in order to disseminate the use of breast ultrasonography and provide education, training, and quality control for the institutions.
2. Implementation of a randomized controlled trial (RCT) to examine the effectiveness of ultrasonography:
a. A total of 76,196 women in their 40's given informed-consent and participated in the RCT after the study were initiated.
b. This is a nationwide study, with participation of 41 institutions from 23 prefectures. Study participation of the groups began in 2007, respectively, demonstrating the feasibility of large-scale clinical trials in Japan.
