Background: Triple negative breast cancers (TNBCs) are high grade aggressive tumors generally with a poor prognosis, not responding to hormonal and anti Her2 Neu therapy. Expression of the antiapoptotic B cell lymphoma 2 gene (Bcl2) is associated with low grade, slowly proliferating hormone receptor positive tumors with improved survival. Anti Bcl2 agents can be used as alternative targeted therapy in triple negative cancers.
Materials And Methods: The objective of this study was to determine the immunohistochemical expression of Bcl2 in triple negative breast cancers and any correlation with clinicopathological variables in Northern Pakistan.
Results: All 52 patients were females, aged between 28 and 80 years(average 48.0±12.1). 28 cases (53.8%) were positive for Bcl2, this being associated with low grade invasive ductal carcinomas, lymph node metastasis and lymphovascular invasion.
Conclusions: Bcl2 may be an important prognostic factor and its expression might be used for targeted therapy using Anti Bcl2 drugs.

Tumor-associated neutrophils (TANs) play a critical role in the progression and prognosis of triple-negative breast cancer (TNBC), with N2-type TANs known for their pro-tumor characteristics. This study introduces CT-1, a derivative of cryptotanshinone that effectively suppresses TNBC growth while selectively reducing the proportion of N2-type TANs within tumor tissue. Notably, CT-1 induces simultaneous ferroptosis in both N2-type TANs and TNBC cells, a dual mechanism that enhances its therapeutic efficacy.

Spatial profiling of tissues promises to elucidate tumor-microenvironment interactions and generate prognostic and predictive biomarkers. We analyzed single-cell, spatial data from three multiplex imaging technologies: cyclic immunofluorescence (CycIF) data we generated from 102 breast cancer patients with clinical follow-up, and publicly available imaging mass cytometry and multiplex ion-beam imaging datasets. Similar single-cell phenotyping results across imaging platforms enabled combined analysis of epithelial phenotypes to delineate prognostic subtypes among estrogen-receptor positive (ER+) patients.

Recent advances in cancer therapy have been made possible by monoclonal antibodies, domain antibodies, antibody drug conjugates, The most impact has come from controlling cell cycle checkpoints through checkpoint inhibitors. This manuscript explores the potential of a series of novel -benzyl isatin based hydrazones (5-25), which were synthesized and evaluated as anti-breast cancer agents. The synthesized hydrazones of -benzyl isatin were screened against two cell lines, the MDA-MB-231 breast cancer cell line and the MCF-10A breast epithelial cell line.

Background: It is worthwhile to establish a prognostic prediction model based on microenvironment cells (MCs) infiltration and explore new treatment strategies for triple-negative breast cancer (TNBC).
Methods: The xCell algorithm was used to quantify the cellular components of the TNBC microenvironment based on bulk RNA sequencing (bulk RNA-seq) data. The MCs index (MCI) was constructed using the least absolute shrinkage and selection operator Cox (LASSO-Cox) regression analysis.
Metastatic triple-negative breast cancer has a poor prognosis and poses significant therapeutic challenges. Until recently, limited therapeutic options have been available for patients with advanced disease after failure of first-line chemotherapy. The aim of this review is to assess the current evidence supporting second-line treatment options in patients with metastatic triple-negative breast cancer.
