Abstract
BackgroundDuctal carcinoma in situ (DCIS) is associated with low rates of mortality. Outcomes are generally assessed in terms of recurrence.MethodsPublished studies were abstracted from MEDLINE and other sources. We include articles published through January 31, 2009; 10 publications of five randomized controlled trials and 133 publications of 64 observational studies were reviewed.ResultsWhole-breast radiation therapy following breast-conserving surgery (BCS) was consistently associated with a reduced incidence of local DCIS recurrence and local invasive carcinoma. Women undergoing mastectomy were less likely than women undergoing lumpectomy with or without radiation to experience local DCIS or invasive recurrence. Tamoxifen use reduced risk of recurrent DCIS or invasive carcinoma.ConclusionsBCS plus radiation and mastectomy appear to yield equivalent outcomes, whereas BCS alone tends to be inferior to mastectomy. Tamoxifen seems helpful in treating DCIS.
