“…A number of studies have reported referral delays of oral cancer in Australia (Dimitroulis et al, 1992), Brazil (Kowalski et al, 1994), United Kingdom (Hollows et al, 2000), Denmark (Wildt et al, 1995) and Greece (Pitiphat et al, 2002), however the studies are not easily comparable because they were set in different areas and used different methodologies.…”

The incidence of oral cancer is rising in the Sudan. Detecting oral cancer at an early stage is the most effective means of improving survival and reducing morbidity from disease. Aim:The aim of the present study was to determine the knowledge, attitude and practice of dentists related to oral cancer prevention and early detection in public dental clinics in Khartoum State, Sudan. Materials and Methods:A cross-sectional survey using an administered structured questionnaire was carried out. The questionnaire consisted of 28 questions that included the key areas of oral cancer prevention and early detection. A sample of 130 dental practitioners was requested to participate in the study. Results:The response rate was 86.92%. The majority were female (68.1%) between the ages of 20 -40 years old. The majority were aware of the major risk factors and the most common presentations of oral cancer. About two thirds (63.7%) perceived that their knowledge on oral cancer was current. However, almost a third (35.4.6%) reported that they had sufficient knowledge concerning oral cancer prevention. More than half (54 percent) reported that they do not carry out any special examination to detect oral cancer in asymptomatic patients. Two thirds (66.3%) believed that their undergraduate training in the diagnosis of oral cancer was inadequate. The vast majority (95.6%) were interested in further oral cancer continuing education and 88.5% that development of referral guidelines can improve the quality of referrals to specialists. Conclusions:The findings of the present study indicate that there is a need for further training in the early detection and prevention of oral cancer, as well as an increased emphasis on oral cancer diagnosis and prevention in the dental training curriculum.3 Declaration I, the undersigned, hereby declare that the work contained in this dissertation is my original work and that it has not been previously in its entirety or in part submitted at any university for a degree.………………………………… …………………………

“…Os carcinomas pouco diferenciados e indiferenciados são mais agressivos, por possuírem uma característica mais infiltrativa, quando comparados aos moderadamente diferenciados e os bem diferenciados 3,28 . A larga maioria dos nossos pacientes apresenta-se com tumores no estádio avançado, T3 (32.4%) e T4 (50.7%) 8,23,29 .…”

OBJETIVO: Analisar o padrão de disseminação local através da delimitação clínica da extensão da lesão primária assim como os subsítios invadidos. FORMA DE ESTUDO: Clínico retrospectivo. MATERIAL E MÉTODO: Foram analisados os prontuários de 290 pacientes com carcinoma epidermóide de base de língua no Departamento de Cirurgia de Cabeça e Pescoço e Otorrinolaringologia do Hospital Heliópolis, Hosphel, São Paulo - Brasil, de 1977 a 2000, sendo estadiados pelo TNM da UICC, e os resultados analisados pelo teste do Quiquadrado para tabelas Z x N (Cochran) para estudo da associação dos sítios e dimensão da neoplasia em relação à invasão da linha média. RESULTADOS: Com predomínio dos homens (8:1) e da 6ª década de vida (41,0%), 83,8% eram etilistas e tabagistas e em 4,7% os hábitos estavam ausentes. Quanto aos sintomas, odinofagia (37,6%), linfonodo (21,7%) e a média de tempo entre o 1º sintoma e o diagnóstico de 6 meses (62,0%). Quanto ao estadiamento, tivemos T1-T2 (18,3%), T3 (32,4%), T4(50,7%). Quanto à disseminação local, em direção à valécula (25,3%), epiglote (18,7%), glote (2,7%), anteriormente para o v lingual em (22,4%) e póstero lateralmente para a prega faringloepiglótica (6,6%) e seio piriforme (2,2%). Quanto a ultrapassagem da linha média, isso ocorreu em 66,2% dos casos, sendo 42,2% (T2), 54,2% (T3) e 82,9% (T4). CONCLUSÃO: o carcinoma epidermóide no estádio T4 ultrapassa a linha média da base da língua em 82,9%.

“…1 However, other large-scale research has revealed no significant difference in professional delay of oral malignancies between dentists and physicians, 2-6 whereas other publications conclude that dentists refer patients at earlier stages than physicians do. [7][8][9][10][11] According to Holmes et al, 11 oral-or oropharyngeal-squamous cell carcinoma (SCC) patients referred from dental offices were of significantly lower stage (TMN 1.94) than those referred from medical offices (TMN 3.00). As many as 72% of patients referred by physicians and ENT specialists were of advanced stages and only 21% of the patients referred by dentist and dental hygienists.…”
