Records of 407 patients with primary breast cancer treated at the M.D. Anderson Hospital in 1958 and 1959 were reviewed with regard to patient characteristics, treatment, and results. These patients presented with relatively advanced disease (42% were inoperable on initial evaluation). Black and Chicano patients had significantly more advanced disease on admission than did white patients. Approximately 61% of patients received treatment appropriate to their clinical category indicating that multiple factors influence therapy selection. Absolute ten-year survival free of disease was 21%. Black and Chicano patients with early disease (categories 1 and 2) had significantly worse survival than did white patients. Problems with retrospective studies are multiple and limit the validity of conclusions. Randomized controlled studies are essential to answer critical questions.

Background: Hereditary predisposition to breast and ovarian cancer syndrome (HBOC) is a pathological condition with increased cancer risk, including breast (BC), ovarian cancer (OC), and others. HBOC pathogenesis is caused mainly by germline pathogenic variants (GPV) in BRCA1 and BRCA2 genes. However, other relevant genes are related to this syndrome diagnosis, prognosis, and treatment, including TP53, PALB2, CHEK2, ATM, etc.

Background: With recent advances in single cell technology, high-throughput methods provide unique insight into disease mechanisms and more importantly, cell type origin. Here, we used multi-omics data to understand how genetic variants from genome-wide association studies influence development of disease. We show in principle how to use genetic algorithms with normal, matching pairs of single-nucleus RNA- and ATAC-seq, genome annotations, and protein-protein interaction data to describe the genes and cell types collectively and their contribution to increased risk.

Purpose: Breast cancer, as a stressful event, profoundly impacts the entire family, especially patients and their spouses. This study used a dyadic analysis approach to explore the dyadic effects of illness perception on the fear of cancer recurrence (FCR) and whether maladaptive cognitive-emotional regulation strategies acted as a mediator in breast cancer patient-spouse dyads.
Methods: This was a cross-sectional study, and 202 dyads of breast cancer patients and their spouses were enrolled.

Background: In recent years, there has been a growing number of case reports documenting delayed seroma in patients with a history of breast surgery and reconstruction. The occurrence of these seromas has been associated with prior SARS-CoV-2 infection or SARS-CoV-2 vaccination. So far, there are few systematic analyses on postoperative complications in breast surgery since the emergence of the SARS-CoV-2 pandemic.
