    關鍵信息

    該篇回顧性綜述評估了292名患者進行保乳手術（BCS）后能夠預測陽性手術切緣的危險因素。作者發(fā)現腫瘤多峰性趨勢和組織學檢查為非導管癌與再次切除相關，但這一發(fā)現并無統(tǒng)計學差異。

    在該研究中，風險值計算圖與出現手術切緣陽性無顯著相關性。

    TAKE-HOME MESSAGE

    The authors of this retrospective review of 292 patients evaluated risk factors that would predict positive surgical margins after breast-conserving surgery （BCS）。 The authors found trends that tumor multifocality and non-ductal histology were associated with re-excision, but these findings were not statistically significant.

    In this study, there was no significant correlation with the nomogram-calculated risk values and the presence of positive surgical margins.
