[Change in the incidence of diabetes mellitus in oral cancer patients based on a long-term comparative study].

Our research is focused on the incidence of diabetes mellitus and glucose metabolic disorders among oral cancer patients and the frequency of different oral localizations of cancer. Diabetes mellitus affects 7% of the Hungarian population. This study uses data spanning 14 years, with 2 datasets of 1998-1999 and 2012-2013, collected first hand by the authors. These datasets have led us to examine the blood glucose level in 267 patients with histologically confirmed malignant tumours in the oral cavity. Diabetes mellitus was found in 59 of them (22.1%), The blood glucose was elevated in 32 cases (12%). The most frequent tumor locations among the diabetic patients: labial, lingual and gingival tumors gingivae. Comparative epidemiological study demonstrates that in 2012-2013 dataset there was an increased observed percentage of people with diabetes mellitus [17.6% to 22.1%]. The percentage of patients with IFG (impaired fasting glucose) also increased from 9.8% to 12%. Overall the number of patients with glucose metabolic disorders climbed from 27.4% to 34.1%, (p > 0.05). Our intention of this introductory analysis is to emphasize the close connection of these two very important disease groups, and the wider spread of diabetes mellitus.
