The oral cancer is the fifth more frequent neoplasia in the brazilian population with a high mortality rate. The objective of this paper is avaliate the impact about prognosis and treatment among the patients who underwent surgery for oral squamous cell carcinoma (SCC) in the Integrated Oncology Center of the Ana Nery Hospital - Santa Cruz do Sul, Brazil, after restaging from launch of the new Manual of classification of tumors (TNM eighth edition). Were reviewed 56 patient records of patients operated by oral SCC retrospectively. Several clinical and epidemiological studies were carried out, including clinical and pathological staging, applying the seventh and eighth issues of TNM and survival and mortality data. Cases with upstaging from N2 to N3 had a 50% mortality compared to 7.1% with N2 staging. The cases with upstaging of T1 or T2 for T3 have a 30% mortality compared to 6.6% in T1 and 0% in T2. Only 1 of the cases with upstaging for N3 did not do adjuvant chemotherapy and only one of the cases with upstaging for T3 did not do adjuvant chemotherapy with RT. The new staging predicts more appropriately or prognosis. Although staging changes have occurred recently, treatment protocols already have been following the recommendations of the latest guidelines.
