Primary Breast Cancer Patients Treated with Breast-Conserving Therapy and Tamoxifen

Abstract

Objective To study whether Japanese breast cancer patients obtain favourable results with breast-conserving surgery if the same selection criteria as those for Western patients are used, and, simultaneously, to assess the outcome of breast-conserving surgery alone versus breast-conserving surgery followed by either irradiation of the remaining breast or adjuvant chemotherapy with tamoxifen.
