Despite new therapeutic approaches patients with advanced oral squamous cell carcinoma still have a dismal prognosis. The main factor contributing to this problem is locoregional failure due to a lack of response to treatment. Several trials have proven the effect of neoadjuvant radiochemotherapy followed by radical surgery in comparison to primary surgery followed by adjuvant radiochemotherapy. No reliable parameters have been identified so far to predict response to radiochemotherapy. The aim of our study was to assess whether podoplanin expression in pretreatment biopsies could serve as a biomarker to predict the host response to neoadjuvant radiochemotherapy. In this retrospective study, podoplanin expression was examined in a set of 63 patients with oral squamous cell carcinoma by immunohistochemistry. We analyzed associations between the level of podoplanin expression and various clinicopathologic parameters, including response to radiochemotherapy, clinical and histological N-status. Furthermore we evaluated the effects of these parameters on overall survival and on locoregional control in univariate and multivariate analysis. The χ(2)-test revealed that high expression of podoplanin in pretreatment biopsy material was associated with non-regression of the tumor (p=0.013) and poor overall survival (p

    Although the radiographic fusion rate was low, when the 7 patients who had an asymptomatic nonunion were combined with the radiographic union group, the overall rate of functional limb salvage rose to 71%. TTC arthrodesis using femoral head allograft should be considered a salvage procedure that is...
