Expression and clinical significance of TrkB in sinonasal squamous cell carcinoma: a pilot study

Previous studies have confirmed that tropomyosin-related kinase B (TrkB) plays a critical role in the occurrence, development, and metastasis of many kinds of malignant tumour. More recently, TrkB was found to be overexpressed in head and neck squamous cell carcinoma (SCC) and to be involved in multistep tumour progression. In this study, the expression of TrkB was investigated in 27 cases of sinonasal SCC using an immunohistochemical method. The clinical significance and possible role of TrkB as a prognostic marker in these tumours was also explored.
