Our research aimed to determine an optimal cutoff value and investigate the prognostic predictive function of Ki-67. We retrospectively enrolled 1146 patients diagnosed with stage I-II triple-negative breast cancer. Disease-free and overall survival were analyzed using the Kaplan-Meier method and the Cox regression model. We classified Ki-67 >45% as the high group (n = 716). A Ki-67 level of >45% was associated with poorer disease-free survival (p = 0.039) and overall survival (p = 0.029). Lymph node stage, neoadjuvant chemotherapy, and radiotherapy were independent predictive variables of prognosis. Triple-negative breast cancer may be further subcategorized according to the Ki-67 level. Neoadjuvant chemotherapy and postoperative radiotherapy can improve the prognosis of early triple-negative breast cancer.

Triple-negative breast cancers (TNBCs) lack predictive biomarkers to guide immunotherapy, especially during early-stage disease. To address this issue, we used single-cell RNA sequencing, bulk transcriptomics, and pathology assays on samples from 171 patients with early-stage TNBC receiving chemotherapy with or without immunotherapy. Our investigation identified an enriched subset of interferon (IFN)-induced CD8 T cells in early TNBC samples, which predict immunotherapy nonresponsiveness.

Triple-negative breast cancer (TNBC) is a particularly aggressive subtype of breast cancer with high metastatic potential, limited treatment options, and low patient survival rates. By combining functional proteomics and genomics approaches, we identified an oncogenic transcriptional network in mesenchymal and invasive TNBC involving the glucocorticoid receptor (GR), GATA6, MYC, and AP-1 transcription factors. Although these transcription factors bound extensively to shared enhancers, they utilized different enhancer repertoires from this shared enhancer pool to drive distinct downstream oncogenic pathways.

Background: The roles of long non-coding RNAs (lncRNAs) in the progression of various human tumors have been extensively studied. However, their specific mechanisms and therapeutic potential in Triple-Negative Breast Cancer (TNBC) remain to be fully elucidated.
Materials And Methods: The qRT-PCR assay was utilized to assess the relative mRNA levels of TFAP2A-AS1, PHGDH, and miR-6892.

Purpose: Advanced, pre-treated TNBC has a dismal prognosis and lacks effective options beyond standard cytotoxics. We previously showed, via phosphoproteomic screening, that CDK6 and ERK hyperactivation are linked to adverse outcomes and represent actionable targets. This prompted us to evaluate palbociclib and binimetinib in advanced TNBC after one or two prior therapies.

Triple-negative breast cancer (TNBC) is the most aggressive breast cancer subtype, characterized by a high propensity for metastasis, poor prognosis, and limited treatment options. Research has demonstrated a substantial correlation between the expression of protein arginine N-methyltransferase 1 (PRMT1) and enhanced proliferation, metastasis, and poor outcomes in TNBC. However, the specific role of PRMT1 in lung metastasis and chemoresistance remains unclear.
