Prospective study: Impact of breast magnetic resonance imaging on oncoplastic surgery and on indications of mastectomy in patients who were previously candidates to breast conserving surgery.

Background: Routine use of magnetic resonance imaging (MRI) in the staging of patients with early breast cancer is still controversial. Oncoplastic surgery (OP) allows for wider resections without compromising the aesthetic results. This study aimed to assess the impact of preoperative MRI on surgical planning and on indications of mastectomy.

Prepectoral Direct-to-Implant Breast Reconstruction without Placement of Acellular Dermal Matrix or Mesh after Nipple-Sparing Mastectomy.

Background: The aim of this study was to report the results of prepectoral direct-to-implant reconstruction in nipple-sparing mastectomy without acellular dermal matrices or mesh.

Methods: A multicenter cohort of patients undergoing prophylactic or therapeutic nipple-sparing mastectomy was included from 2013 to 2020. All sizes and types of breasts were included, except those with previously failed reconstruction, previous radiotherapy with severe skin damage, locally advanced breast cancer, gigantomasty, severe degree of ptosis, tumors close to the nipple-areola complex (<1 cm on magnetic resonance imaging), or combined autologous-based reconstruction.

MicroRNAs miR-142-5p, miR-150-5p, miR-320a-3p, and miR-4433b-5p in Serum and Tissue: Potential Biomarkers in Sporadic Breast Cancer.

Breast cancer (BC) is a heterogeneous disease, and establishing biomarkers is essential to patient management. We previously described that extracellular vesicle-derived miRNAs (EV-miRNAs) miR-142-5p, miR-150-5p, miR-320a, and miR-4433b-5p in serum discriminated BC from control samples, either alone or combined in a panel. Using these previously described markers, we intend to evaluate whether the same markers identified in EVs are also potential biomarkers in tissue and serum.

Exposed Implant after Immediate Breast Reconstruction - Presentation and Analysis of a Clinical Management Protocol.

Objective:  Infection and exposure of the implant are some of the most common and concerning complications after implant-based breast reconstruction. Currently, there is no consensus on the management of these complications. The aim of the present study was to review our cases and to present a clinical protocol.

Cancer stem cell markers ALDH1 and CD44+/CD24- phenotype and their prognosis impact in invasive ductal carcinoma.

Breast cancer is a very heterogeneous disease. The intrinsic molecular subtypes can explain the intertumoral heterogeneity and the cancer stem cell (CSC) hypothesis can explain the intratumoral heterogeneity of this kind of tumor. CD44+/CD24- phenotype and ALDH1 expression are the major CSC markers described in invasive breast cancer.
