Objective. Podoplanin is a mucin-like glycoprotein that is important in lymphangiogenesis but not in blood vessel formation. The aim of this preliminary study is to determine the role of podoplanin in the development and progression of head and neck cancer. Material and Methods.Podoplanin over expression was analyzed in 20 patients with oral cancer, by immunohistochemical analysis. Result. Podoplanin is not expressed in normal oral epithelial cells but was found in some hyperplastic and dysplastic lesions. Podoplanin high expression was found in 9 of 20 patients and was more frequent in cancers with lymph node metastasis, particularly in oral cavity cancers. In our preliminary study, patients who showed high levels of podoplanin had a statistically greater rate of lymph node metastasis (P<0,001); patients with lymph node metastasis and high-level podoplanin showed a shorter disease-specific survival (P = 0,004) than other patients. Conclusion. The results of our preliminary study have provided interesting and encouraging data. We have observed that podoplanin expression increases in the early stages of tumourigenesis and it seems to be associated with a higher risk of head and neck cancer. While in squamous cell carcinoma podoplanin expression diminishes during tumour progression. These data support a role for podoplanin expression in the initiation but not in the progression of cancer. So we can conclude that podoplanin is involved in oral oncogenesis and can be a predictor for lymph node metastasis in asymptomatic patients. Histology and podoplanin analysis can be very useful to predict the risk of development, invasion and metastatic progression of a tumour in patients with oral cancer.
