Tumor localization is challenging in the context of ductal carcinoma situ (DCIS) treated with breast-conserving surgery. Conventional methods are generally performed under guidance ultrasonography or mammography and rarely magnetic resonance imaging (MRI), which more sensitive than aforementioned modalities detecting DCIS. Here, we report application MRI-based individualized 3-dimensional (3D)-printed breast surgical guides (BSGs) for patients cancer. We successfully resected indeterminate suspicious lesions that were only detected using preoperative MRI, final histopathologic results confirmed DCIS clear resection margins. MRI combined 3D-printed BSGs can be used localization, especially easily detectable only.
