The Role of Stromal Tumor Environment in Advancing Skin Cancer Diagnosis and Treatment

The stromal tumor environment (STE) plays a vital yet often underrecognized role in cancer progression, shaping tumor development. It influences complex interactions among stromal cells, immune cells, extracellular matrix (ECM) components, and signaling molecules. Stromal cells regulate integrin signaling and are involved in remodeling the tumor microenvironment, driving critical processes such as cell migration, survival, angiogenesis, and proliferation. Advances in understanding the STE are creating new opportunities for early cancer detection and treatment. Innovations in molecular imaging, particularly for melanoma, are transforming cancer diagnostics by providing deeper insights into tumor biology, cellular interactions, and angiogenesis, paving the way for more personalized and timely therapeutic interventions. Among these advancements, in vivo skin fluorescent imaging (SFI) stands out as a powerful tool, offering real-time molecular insights at the point of care with the ability to improve patient management.
