Improved Local Control Rate in 3-dimensional Radiation Therapy Era in Early Breast Cancer After Breast-conserving Surgery

Abstract

From 1980s several randomized trials have shown that breast-conserving surgery followed by radiotherapy (breast-conserving therapy [BCT]), is as effective as mastectomy for the treatment of breast cancer in the aspect of survival. However, higher local recurrence rate in BCT group was consistently reported in long-term results. This study comprehensively reviewed the clinical data and treatment outcomes of early breast cancer of one institution. We focused on the local recurrence rate and survival according to treatment regimens. Background
