A descriptive study was conducted in “Maria Curie” Oncological Provincial Teaching  Hospital in order to characterize oral  cancer from the clinical and epidemiologic point of view between 1999 and 2004. 79 patients of a total of 285 were studied and 206 with lip cancer were excluded.  Variables such as age groups, sex, risk factors, clinical manifestations, anatomical localization, histological type, clinical form, clinical stage and therapeutical modality were analyzed. The statistical processing was carried out by descriptive statistics, contingency tables and graphs. Percentage and proportion test were used as a summary measure. The disease predominated in patients aged 70-79, with 24 (30.38 %), and in males, with 59 patients (74.68 %).  Smoking was detected in 38 of them (48.10 %), of whom 35 (44.30) referred to pain as the main symptom.  The epidermoid carcinoma was the most frequent histological variety (76, accounting for 96.20 %). Its localization prevailed in the tongue (24 cases, 30.38 %). The diagnosis was commonly made in stage III (42 patients, 53.16 %), and the mixed clinical form predominated (38, 48.10 %). Radiotherapy was the most used treatment in its different variants with 64 cases (81.0 %).
