Gene,It is not clear that the risk of ipsilateral breast tumor recurrence is increased.,At a substantially increased risk of new primary breast cancers in both the ipsilateral and contralateral breast,广泛的导管内癌成分(EIC),EIC阳性是保乳术后局部高复发的原因之一，可能有残留的肿瘤超过了原发肿瘤范围。,切缘阴性、close（切缘与肿瘤之间少于2mm）、阳性之间的局部复发有相当差别。,5年LRR：,EIC()15，EIC(-)1。,因此,EIC可能仅是肿瘤比较广泛的标志，并不是保乳的禁忌症，只要手术边缘阴性就,可达到较好局控率。,保乳手术与切缘距离,对浸润性乳腺癌，染料标记的切缘阴性即可，对导管内癌，切缘距离要求为2 mm，同时术后须钼靶摄片证实钙化灶已被完全切除。,100%的专家支持切缘有浸润性癌或导管内癌必须行再次扩大切除，而切缘存在小叶原位癌时则不需要。对于导管内癌切缘距离小于2 mm时是否须行扩大切除，专家意见不一致。,“Tumor-free Margins”?,SG-Panel 2009 Considerations,Shall re-excision be compulsary in case of
