Clinical and biological heterogeneities in triple-negative breast cancer reveals a non-negligible role of HER2-low
HER2-low could be found in some patients with triple-negative breast cancer (TNBC). However, its potential impacts on clinical features and tumor biological characteristics in TNBC remain unclear. We enrolled 251 consecutive TNBC patients retrospectively, including 157 HER2-low (HER2 ) and 94 HER2-n...

description | HER2-low could be found in some patients with triple-negative breast cancer (TNBC). However, its potential impacts on clinical features and tumor biological characteristics in TNBC remain unclear.
We enrolled 251 consecutive TNBC patients retrospectively, including 157 HER2-low (HER2

TNBC, HER2
TNBC patients exhibited malignant clinical features with larger tumor size (P = 0.04), more lymph nodes involvement (P = 0.02), higher histological grade of lesions (P < 0.001), higher Ki67 status (P < 0.01), and a worse prognosis (P < 0.001; HR [CI 95%] = 3.44 [2.10-5.62]). Cox proportional hazards analysis showed that neoadjuvant systemic therapy, lymph nodes involvement and Ki67 levels were prognostic factors in HER2
TNBC but not in HER2
TNBC patients. ScRNA-seq revealed that HER2
TNBC which showed more metabolically active and aggressive hallmarks, while HER2
TNBC exhibited signatures more involved in immune activities with higher expressions of immunoglobulin-related genes (IGHG1, IGHG4, IGKC, IGLC2); this was further confirmed by immunofluorescence in clinical TNBC samples. Furthermore, HER2
and HER2
TNBC exhibited distinct tumor evolutionary characteristics. Moreover, HER2
TNBC revealed a potentially more active immune microenvironment than HER2
TNBC, as evidenced by positively active regulation of macrophage polarization, abundant CD8
effector T cells, enriched diversity of T-cell receptors and higher levels of immunotherapy-targeted markers, which contributed to achieve immunotherapeutic response.
This study suggests that HER2
TNBC patients harbor more malignant clinical behavior and aggressive tumor biological properties than the HER2
phenotype. The heterogeneity of HER2 may be a non-negligible factor in the clinical management of TNBC patients. Our data provide new insights into the development of a more refined classification and tailored therapeutic strategies for TNBC patients.</description><identifier>ISSN: 1465-542X</identifier><identifier>ISSN: 1465-5411</identifier><identifier>EISSN: 1465-542X</identifier><identifier>DOI: 10.1186/s13058-023-01639-y</identifier><identifier>PMID: 36998014</identifier><language>eng</language><publisher>England: BioMed Central Ltd</publisher><subject>Bar codes ; Breast cancer ; Breast Neoplasms ; Cancer therapies ; CD8 antigen ; Clinical outcomes ; Effector cells ; ErbB-2 protein ; Female ; Gene expression ; HER2-low ; Heterogeneity ; Humans ; Immunofluorescence ; Immunotherapy ; Ki-67 Antigen ; Lymph nodes ; Lymphocytes T ; Macrophages ; Medical prognosis ; Medical records ; Medical research ; Medicine, Experimental ; Microenvironments ; Phenotypes ; Prognosis ; Retrospective Studies ; RNA sequencing ; Single-cell RNA sequencing ; T cells ; Triple Negative Breast Neoplasms - drug therapy ; Triple Negative Breast Neoplasms - therapy ; Triple-negative breast cancer ; Tumor microenvironment ; Tumor Microenvironment - genetics ; Tumors</subject><ispartof>Breast cancer research : BCR, 2023-03, Vol.25 (1), p.34-34, Article 34</ispartof><rights>2023.
