PP047: Squamous cell carcinoma of the tongue. An 11-year experience

Background Squamous cell carcinoma (SCC) of the tongue is one of the most common cancers in the oral and maxillofacial region. The incidence of SCC of the tongue has increased during the recent decades in the developed world. The incidence of occult cervical lymph node metastasis is high in SCC of the tongue and the role of neck dissection in the management and its relevance to locoregional control is well known. Patients Complete clinical, histopathological and follow up data of 88 patients with pathologically confirmed SCC of the tongue were retrospectively analysed. All patients were treated at our Oral and Maxillofacial Surgery Department between 2000 and 2010 and all of them underwent a resection of the primary tumor and a neck dissection. Methods Overall and disease-free survival in relation to demographic characteristics of the patients and pathological features of the specimens is being investigated. Survival analysis is performed using the Kaplan–Meier analysis, comparisons among groups are analysed using a log-rank test and multivariate analysis is conducted using the cox proportional hazard model. Results They will be presented during the meeting.
