Ultrasound Measurement of the Distance between the Breast Tumor and the Skin: A Cut-Off Value for Safe Skin Preservation - Diagnostic Accuracy Study.

Background: In superficial tumors of the breast, it is necessary to plan the thickness of surgical skin flaps, and whether skin can be preserved for esthetics results. This study aimed to find an ultrasound-measured cut-off distance between tumor and skin (TSD) that allows patients to have the skin over the tumor spared.

Methods: This is a diagnostic accuracy study comparing preoperative ultrasound TSD with pathological TSD and the thickness of the skin flaps.

Survival and recurrence with or without axillary dissection in patients with invasive breast cancer and sentinel node metastasis.

To evaluate overall survival and locoregional recurrence between patients with invasive breast tumours and sentinel node metastasis undergoing sentinel lymph node dissection (SLND) alone and those undergoing complete axillary lymph node dissection (ALND). In this retrospective cohort study, we reviewed the medical records of patients with invasive breast carcinoma who underwent lumpectomy at a public university hospital in Brazil between 2008 and 2018. We evaluated the overall survival and the locoregional recurrence using Kaplan-Meier and Cox regression analyses, respectively.

Ductal Carcinoma in situ: Underestimation of Percutaneous Biopsy and Positivity of Sentinel Lymph Node Biopsy in a Brazilian Public Hospital.

Background: Mammography screening has become widely spread and provided a marked increase in ductal carcinoma in situ (DCIS) diagnosis. In DCIS, the ductal epithelium proliferates without invasion through the basal cell membrane. However, histologic underestimation can happen in some cases.

Awareness of Self-Examination, Screening, and Risk Factors for Breast Cancer Among Women Awaiting Care at the Outpatient Clinic of a Mastology Unit.

This study aimed to evaluate the awareness and practice of breast self-examination (BSE) and the awareness of screening and risk factors for breast cancer among patients from a mastology clinic and to associate such findings with sociodemographic factors of that population. A total of 202 randomly selected patients from the outpatient clinic of the Mastology Unit of São Paulo School of Medicine were interviewed. A structured questionnaire was used and included questions regarding sociodemographic variables, questions to assess the knowledge and practice of BSE, and knowledge of mammographic screening and risk factors for breast cancer.

Evaluation of the Efficacy of Clinical Breast Examination Gloves in the Diagnosis of Breast Lumps.

Introduction: Recent studies have questioned the efficacy of mammography in reducing breast cancer-related mortality. Additionally, the efficacies of commercially available gloves marketed as aiding the detection of breast lumps have not been independently verified.

Aim: To evaluate the efficacy of clinical breast examination gloves in the detection of breast lumps.
