Article Abstract
Objectives: To downgrade BI-RADS 4A patients by constructing a nomogram using R software.
Materials And Methods: A total of 1,717 patients were retrospectively analyzed who underwent preoperative ultrasound, mammography, and magnetic resonance examinations in our hospital from August 2019 to September 2020, and a total of 458 patients of category BI-RADS 4A (mean age, 47 years; range 18-84 years; all women) were included. Multivariable logistic regression was used to screen out the independent influencing parameters that affect the benign and malignant tumors, and the nomogram was constructed by R language to downgrade BI-RADS 4A patients to eligible category.
Results: Of 458 BI-RADS 4A patients, 273 (59.6%) were degraded to category 3. The malignancy rate of these 273 lesions is 1.5% (4/273) (<2%), and the sensitivity reduced to 99.6%, the specificity increased from 4.41% to 45.3%, and the accuracy increased from 63.4% to 78.8%.
Conclusion: By constructing a nomogram, some patients can be downgraded to avoid unnecessary biopsy.

Purpose: This study aimed to evaluate the performance of ChatGPT (GPT-4o) in interpreting free-text breast magnetic resonance imaging (MRI) reports by assigning BI-RADS categories and recommending appropriate clinical management steps in the absence of explicitly stated BI-RADS classifications.
Methods: In this retrospective, single-center study, a total of 352 documented full-text breast MRI reports of at least one identifiable breast lesion with descriptive imaging findings between January 2024 and June 2025 were included in the study. Incomplete reports due to technical limitations, reports describing only normal findings, and MRI examinations performed at external institutions were excluded from the study.
A novel technology for margin extension and local control in breast conservation surgery: Saline-coupled intraoperative radiofrequency ablation (SIRA).

Importance: Breast-conserving therapy (BCT) results in reoperation in ∼20 % of cases due to positive margins, and a 7-13 % recurrence risk at 5 years persists despite negative margins and radiation. Enhancing margin treatment is critical to reducing local recurrence and improving survival.
Objective: To optimize and evaluate the performance of a Saline-coupled Intraoperative Radiofrequency Ablation (SIRA) device in producing uniform 1 cm ablations in lumpectomy cavities and compare it to prior-generation RFA technology in previous clinical studies.

Background: Research on the psychological distress experienced by women with benign breast disease (BBD) remains limited, though some evidence suggests it may resemble that of women with breast cancer (BC).
Objectives: This study aimed to use the Distress Thermometer (DT) to assess the levels of psychological distress and identify influencing factors during the diagnostic phase in patients with BC and BBD.
Material And Methods: From October 2022 to May 2023, a questionnaire survey incorporating the DT and Problem List (PL) was conducted among inpatients in the diagnostic phase for BC or BBD at the Breast Surgery Department of Shanxi Bethune Hospital (Taiyuan, China).
