Surgical margins negative for DCIS should be obtained after BCS for DCIS. A margin threshold of 2 mm seems to be as good as a larger margin when BCS for DCIS is combined with RT
There is a difference between Europe and North America regards the amount of normal tissue that should be removed for clear margins in DCIS. In Europe, 10mm is the favoured margin, whereas 1mm may be regarded as clear in North America.
This study shows that a smaller margin combined with radiation therapy is as effective as taking a larger margin
