Nodal Burden and Oncologic Outcomes in Patients With Residual Isolated Tumor Cells After Neoadjuvant Chemotherapy (ypN0i+): The OPBC-05/ICARO Study.

Purpose: The nodal burden of patients with residual isolated tumor cells (ITCs) in the sentinel lymph nodes (SLNs) after neoadjuvant chemotherapy (NAC) (ypN0i+) is unknown, and axillary management is not standardized. We investigated rates of additional positive lymph nodes (LNs) at axillary lymph node dissection (ALND) and oncologic outcomes in patients with ypN0i+ treated with and without ALND.

Methods: The Oncoplastic Breast Consortium-05/ICARO cohort study (ClinicalTrials.

Extracellular Vesicle DNA Extraction and Sequencing in Ancient Serum Samples From Patients With Breast Cancer.

Background/aim: Extracellular vesicle DNA (EV-DNA) has emerged as a novel biomarker for tumor mutation detection using liquid biopsies, exhibiting biological advantages compared to cell-free DNA (cfDNA). This study assessed the feasibility of EV-DNA and cfDNA extraction and sequencing in old serum samples of patients with breast cancer (BC).

Patients And Methods: A total of 28 serum samples of 27 patients with corresponding clinical information were collected between 1983 and 1991.

Association of relative resection volume with patient-reported outcomes applying different levels of oncoplastic breast conserving surgery - A retrospective cohort study.

Introduction: The American Society of Breast Surgeons (ASBrS) recently classified oncoplastic breast conserving surgery (OBCS) into two levels. The association of resection ratio during OBCS with patient-reported outcomes (PRO) is unclear.

Materials And Methods: Patients with stage 0-III breast cancer undergoing OBCS between 01/2011-04/2023 at a Swiss university hospital, who completed at least one postoperative BREAST-Q PRO questionnaire were identified from a prospectively maintained institutional database.

Joint multi-ancestry and admixed GWAS reveals the complex genetics behind human cranial vault shape.

The cranial vault in humans is highly variable, clinically relevant, and heritable, yet its genetic architecture remains poorly understood. Here, we conduct a joint multi-ancestry and admixed multivariate genome-wide association study on 3D cranial vault shape extracted from magnetic resonance images of 6772 children from the ABCD study cohort yielding 30 genome-wide significant loci. Follow-up analyses indicate that these loci overlap with genomic risk loci for sagittal craniosynostosis, show elevated activity cranial neural crest cells, are enriched for processes related to skeletal development, and are shared with the face and brain.
