One-Step Nucleic Acid Amplification System in Comparison to the Intraoperative Frozen Section and Definitive Histological Examination Among Breast Cancer Patients: A Retrospective Survival Study.

Simple Summary: Implementing intraoperative assessment of sentinel lymph nodes by one-step nucleic acid amplification in early breast cancer can reduce the surgical burden to the patient and the costs to the health system. However, only limited data are available in terms of long-term disease-free survival and overall survival. Therefore, this study aims to compare disease-free survival and overall survival between one-step nucleic acid amplification, frozen section, and definitive histology.

Impact of the presence and quantity of ductal carcinoma in situ component on the outcome of invasive breast cancer.

Introduction: The role of ductal carcinoma in situ (DCIS) component on the outcome of invasive breast cancer is not yet completely clear. Our study aims to assess the impact of the presence and quantity of DCIS component on the outcome of patients operated for invasive breast cancer.

Materials And Methods: We collected retrospective data about patients operated at their breast for invasive cancer between 2007 and 2012, focusing on the presence of DCIS component.
