Prognostic Significance of PCNA Expression in Laryngeal Cancer

Abstract
PREDICTING THE outcome of laryngeal cancer is of paramount importance for the physician to decide on the treatment modality. Despite the many investigations on cytologic and morphologic properties, currently there are no absolute criteria that can predict the outcome of laryngeal cancer and guide the physician to select the appropriate therapy and to decide on the extent of surgery and the convenience of neck dissection in patients with N0 tumors. One of the most important criteria that shows the aggressive biological behavior is the cellular proliferation rate of a tumor. Consequently, several proliferation markers have been studied for their relation with the recurrence and metastatic rate of the tumor and mortality.
