NSABP Clinical Trials Overview

Protocol B-24
A Clinical Trial to Evaluate the Worth of Tamoxifen in Conjunction with Lumpectomy and Breast Irradiation for the Treatment of Noninvasive Intraductal Carcinoma (DCIS) of the Breast

Specific Aims
The specific aim for this protocol is to determine, for patients with noninvasive intraductal cancer (DCIS), whether lumpectomy and postoperative breast irradiation plus prolonged tamoxifen therapy is more effective than lumpectomy and breast irradiation without tamoxifen in preventing the subsequent occurrence of ipsilateral and contralateral breast cancers
