p-Akt and its relationship with clinicopathological features and survival in oral squamous cell carcinoma: an immunohistochemical study.

Background: The aim of this study was to evaluate, through immunohistochemical reaction in samples of oral squamous cell carcinoma, the correlation between the expression status of protein kinase B (p-Akt) and patient survival as well as histological grade and some clinicopathological features.

Methods: Samples were collected from 46 patients with oral squamous cell carcinoma. The immunohistochemical expression of p-Akt was analysed, as were clinicopathological features including the use of tobacco, tumour stage, size and infiltration of metastatic lymph nodes.
