When metastases were found, they were further subdivided by size into isolated tumor-cell clusters (0.2 mm or less), micrometastases (between 0.2 and 2.0 mm), and macrometastases (greater than 2.0 mm). The present retrospective study examined the overall survival and prognostic factors associated with OBC in Korea.
