AI Article Synopsis

  • The research aimed to explore how various immune cells influence breast cancer survival rates and to identify key genes linked to these immune cell types.
  • The study used data from The Cancer Genome Atlas and the Gene Expression Omnibus to assess immune cell presence in breast tissues, applying the CIBERSORT algorithm for analysis.
  • Findings revealed that M1 macrophages and naive B cells improve breast cancer prognosis, while M2 macrophages and monocytes worsen it, indicating the importance of macrophage types in cancer progression and potential therapeutic targets.

Article Abstract

Objective: The purpose of this research was to investigate how different types of immune cells impact the outlook of individuals with breast cancer, as well as identify the essential genes associated with immune cell subtype enrichment.

Methods: The Cancer Genome Atlas (TCGA) database and Gene Expression Omnibus (GEO) database were used to obtain global transcriptome sequencing data sets of breast tissue. The study utilized the CIBERSORT algorithm to determine the presence of 22 different types of immune cells in both breast cancer tissue and normal breast tissue.Immune cell infiltration content was utilized to conduct univariate COX analysis in order to identify risk factors linked to breast cancer prognosis.

Results: Univariate COX analysis indicates that Macrophages M1 and B cells naive are beneficial factors for the outlook of individuals with breast cancer (P < 0.05), while Macrophages M2 and Monocytes are detrimental factors for the prognosis of breast cancer patients (P < 0.05). The high infiltration group of macrophage M2 had a poorer prognosis compared to the low infiltration group (P < 0.001); Conversely, the high infiltration group of macrophage M1 had a better prognosis than the low infiltration group (P = 0.002).

Conclusion: The study provided an overview of immune cell infiltration in breast cancer tissues, identifying macrophage M1 and macrophage M2 as potential factors in breast cancer development and progression. Additionally, genes associated with macrophage phenotype were analyzed, offering insights into macrophage polarization mechanisms.

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.

Detectability of Al18F-NOTA-HER2-BCH PET for Nodal Metastases in Patients With HER2-Positive Breast Cancer.

Clin Nucl Med

January 2025

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).

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.

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.

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.
