AI Article Synopsis
Article Abstract
It is now well accepted that tumor cells actively communicate with the tumor microenvironment (e.g., adipocytes) leading to the progression of breast cancer and other malignancies. It is also known that adipose mesenchymal stem cells (MSCs) have the ability to differentiate into mature adipocytes and initiate cytokine signaling within the tumor microenvironment. Here, we examine the role of MSC-differentiated adipocytes on breast cancer cell migration, and test the effects of sulforaphane (SFN, a dietary chemoprevention agent) on adipocyte-breast cancer cell interaction. Our results demonstrate that SFN promotes MSC self-renewal and inhibits adipogenic differentiation. Subsequently, SFN treatment of adipocytes considerably hinders cytokine communication with breast cancer cells, thereby decreasing breast cancer cell migration and tumor formation.

Safety of topical estrogen therapy during adjuvant endocrine treatment among patients with breast cancer: A meta-analysis based expert panel discussion.
Cancer Treat Rev
January 2025
Department of Oncology, Faculty of Medicine and Health, Örebro University, Örebro, Sweden. Electronic address:
Importance: Endocrine treatments, such as Tamoxifen (TAM) and/or Aromatase inhibitors (AI), are the adjuvant therapy of choice for hormone-receptor positive breast cancer. These agents are associated with menopausal symptoms, adversely affecting drug compliance. Topical estrogen (TE) has been proposed for symptom management, given its' local application and presumed reduced bioavailability, however its oncological safety remains uncertain.

From the Key Laboratory of Carcinogenesis and Translational Research (Ministry of Education/Beijing), NMPA Key Laboratory for Research and Evaluation of Radiopharmaceuticals (National Medical Products Administration), Department of Nuclear Medicine; Peking University Cancer Hospital and Institute, Beijing, China.
Purpose: The aim of this study was to compare Al18F-NOTA-HER2-BCH and 18F-FDG for detecting nodal metastases in patients with HER2-positive breast cancer on PET/CT.
Patients And Methods: In this retrospective study, 62 participants with HER2-positive breast cancer underwent both Al18F-NOTA-HER2-BCH and 18F-FDG PET/CT. Participants were pathologically confirmed as HER2-positive (IHC 3+ or IHC 2+ with gene amplification on FISH).
Pertuzumab Retreatment for Human Epidermal Growth Factor Receptor 2-Positive Locally Advanced/Metastatic Breast Cancer (PRECIOUS Study): Final Overall Survival Analysis.

Breast Surgery, Kyoto University Graduate School of Medicine, Shogoin Sakyo-ku, Kyoto, Japan.
In the primary analysis of the open-label phase III PRECIOUS study, pertuzumab retreatment combined with trastuzumab plus chemotherapy of physician's choice (PTC) significantly improved investigator-assessed progression-free survival (PFS) compared with trastuzumab plus physician's choice chemotherapy (TC) in patients with human epidermal growth factor receptor 2 (HER2)-positive locally advanced/metastatic breast cancer (LA/mBC). Here, we report final overall survival (OS) at the median follow-up of 25.8 months.

Department of Medical Oncology, Peter MacCallum Cancer Centre, Melbourne, Victoria, Australia.
Purpose: To investigate whether hormone receptor-positive, human epidermal growth factor receptor 2-low (HR+HER2-low) versus HR+HER2-zero early breast cancers have distinct genomic and clinical characteristics.
Methods: This study included HR+, HER2-negative early breast cancers from patients enrolled in the phase III, randomized BIG 1-98 and SOFT clinical trials that had undergone tumor genomic sequencing. Tumors were classified HR+HER2-low if they had a centrally reviewed HER2 immunohistochemistry (IHC) score of 1+ or 2+ with negative in situ hybridization and HR+HER2-zero if they had an HER2 IHC score of 0.
Validation of a Single Item Measure for Financial Toxicity Screening in Patients With Breast Cancer.
JCO Oncol Pract
January 2025
College of Population Health, Thomas Jefferson University, Philadelphia, PA.
Purpose: Financial toxicity (FT) has been linked to higher symptom burden and poorer clinical outcomes for patients with cancer. Despite the availability of validated tools to measure FT, a simple screen remains an unmet need. We evaluated item 12 ("My illness has been a financial hardship to my family and me") of the COmprehensive Score for Financial Toxicity (COST) measure as a single-item FT screening measure.
