Toward a Molecular Classification of the Head and Neck Squamous Cell Carcinoma
The frequency of the squamous cell carcinoma of the head and neck is constantly increasing, with over 550.000 new cases registered globally each year. The conventional histopathological diagnosis most commonly indicates the squamous cell carcinoma as tumor type and G2 as differentiation grade. Despite of this relative morphological uniformity, there is a great heterogeneity in the molecular profile, the therapeutic response and prognosis. Most probably, this entity includes many diseases, similar in basic morphologic features, but different in the biological behavior. Trying to answer this question and to show discrepancies when they exist, we have evaluated in this book chapter, our own results and data from the literature in terms of molecular profile at the protein level, including the spectrum of proliferation markers, growth factors and their receptors, stromal proliferation, angiogenesis and lymphangiogenesis. These data will allow to identify some major criteria for a better stratification of cases, selected for gene analysis and personalized therapy as a future perspective and direction.
