Spatial Transcriptomics Reveals Molecular Biological Differences Between IDC and DCIS/LCIS in Breast Cancer
This study employed spatial transcriptomics to elucidate molecular heterogeneity between invasive ductal carcinoma (IDC) and in situ/lobular carcinoma (DCIS/LCIS) in breast cancer. Using 10x Genomics Visium and spaGCN, precise tumor region delineation and identification of transitional boundaries were achieved. Differential expression analysis highlighted significant activation of NF-kB, cancer-related signaling, and p53 pathways in IDC, indicating enhanced proliferation, migration, and immune evasion. Functional enrichment revealed coordinated pathway reprogramming in IDC, reflecting key molecular drivers of invasion. These findings offer insights into breast cancer's spatial molecular landscape and invasion mechanisms, supporting targeted therapy and refined molecular diagnostics.

Precision Oncology for Breast Cancer
The identified molecular distinctions between IDC and DCIS/LCIS highlight opportunities for precision oncology. Targeting activated NF-kB pathways in IDC, for instance, could inhibit proliferation and immune evasion. Similarly, restoring p53 function or enhancing pro-apoptotic pathways could re-sensitize IDC cells to therapy. This spatial transcriptomics-driven approach allows for the development of region-specific therapeutic strategies, minimizing off-target effects and maximizing efficacy.
Outcome: Improved patient outcomes with reduced toxicity by delivering therapies tailored to the specific molecular landscape of the tumor subtype and its spatial context.
