“…Also, most studies from Nigeria have shown oral cancer to be more prevalent in males than females [19,20,48,49]. However, Otoh et al [22] in Maiduguri North-east Nigeria found a male to female ratio of 3:4 and suggested that the relative higher preponderance of females in their study may be attributed to the increasing exposure of females in North-eastern Nigeria to carcinogens such as tobacco and alcohol. Other studies also reported female predilection for oral carcinomas [14,19].…”

“…In Southsouth Nigeria, a study in University of Benin Teaching Hospital, [18] reported palate as the most common site for orofacial carcinomas. Similarly, Otoh et al [22] also reported the palate as the most common site of intraoral carcinomas in northern Nigerians. Some Nigerian studies from Ibadan, however, show that the tongue, palate and the mandibular alveolus are the sites most commonly affected with the floor of mouth and buccal mucosa being the least affected [20,51].…”

“…North central Nigeria reported that oral cancers constitute 7.6% of head and neck cancers (HNC) from a 15-year study of which carcinomas, sarcomas and lymphomas were 81.5%, 16.7% and 1.8% of the cases respectively [21]. In North Eastern Nigeria, Akinmoladun et al [9] in Gombe reported that cancer of the oral cavity constitutes 19.5% of all head and neck malignancies, while Otoh et al [22] in Maiduguri, reported an average rate of 20 cases of oral cancer per annum. Oji and Chukwuneke [14] in South eastern Nigeria reported that oral cancers accounted for 2.7% of all cancer cases seen at the University of Nigeria Teaching Hospital (UNTH) Enugu over a sixyear period.…”

Study background: In our environment, oral cancer is one of the most common lethal diseases encountered in dental practice. It is frequently diagnosed in the late stages because most patients present late in the course of the disease. This may be attributed to their low socioeconomic status, illiteracy, and some traditional beliefs in alternative native therapies. Some authors have reported on oral cancers specifically in their individual geographic settings; however, there is a paucity of reviews on Oral cancers generally in our environment. This study aims to review the prevalence, awareness and clinicopathologic patterns of oral cancers across the different geographic zones in Nigeria.Methods: Information was sourced from journals, electronic data base such as Medline, Pubmed, Elsevier ScienceDirect and personal research work.Result: Several prevalence rates have been reported in different geopolitical locations in our environment. Orofacial carcinomas were reported mostly in the older age groups while the Orofacial sarcomas were found in the slightly younger age groups. Squamous cell carcinoma was the predominant histopathological type. There is a low level of awareness of these lesions among the low socio-economic groups which makes them present late in our health care facilities hence a poor prognosis. Conclusion:There is a need for increased awareness, advocacy and preventive care and early detection.

“…Irritation fibroma occurred in 14.4% of our samples which is similar to the 14.6% presented by Barker and Lucas, 33 but less than that found by Toida et al 24 Considering that irritation fibroma can be affected by oral habits, 34 which in turn are known to be related to social stress and cultural factors, this element may have a role in the differences observed between populations. Squamous cell carcinoma showed a prevalence of 13.8% in the current investigation which falls at the lower end of the 10.7 to 53% 27,[35][36][37] reported in other studies. There is a long list of items affecting the occurrence of squamous cell carcinoma ranging from the use of tobacco to phenolic agents and a number of systemic diseases 19 which can be responsible for these variations.…”

Aim:The aim of the present study was to analyze data on the characteristics of tongue lesions in dental patients seeking care at the Oral Pathology Service of Tehran University of Medical Sciences, from 1985-2010. Materials and methods:Demographic data and histopathologic diagnoses were recorded for all lesions that were documented as occurring on the tongue according to the patient records in our department. Statistical analysis included chi-square, t-, and Fisher's exact tests. A 95% confidence interval (CI) was calculated, and p < 0.05 was considered significant. Results:Tongue lesions constituted 6.3% of all received specimens which included 46 different defects. The most common lesions were lichen planus (LP), irritation fibroma (IF), squamous cell carcinoma (SCC) and pemphigus vulgaris (PV). Tongue lesions were significantly more common in women compared to men (CI = 0.65-0.94, p = 0.02). Mean age (47 years) did not differ between male and female subjects (CI = -2.49 -3.93, p = 0.06). The dorsal surface followed by the lateral aspect was the most common site for tongue lesions.

Carcinome épidermoïde de la tête et du cou dans une population ougandaise: étude épidémiologique descriptive

Introduction: Head and neck squamous cell carcinoma is the seventh most frequent type of cancer in the world, but its prevalence in African countries is about twoto four-folds higher than the developed countries. Despite improved surgical technique, chemotherapeutic and radiation intervention, the mean five-year survival remains one of the lowest among the main cancers, thus justifying studies that contribute to the development of preventive strategies. Objectives: The aim of this study was to compare the epidemiological, clinical, and histological characteristics of 219 patients with head and neck squamous cell carcinoma seen at Mulago National Referral Hospital in Uganda. Results and discussion: Mean age was 58.87 ± 16.29 years and the male/female ratio was 1.3:1.0. Of the 159 patients whose history on smoking was available, 66% confessed to the habit and 63.5% consumed alcohol regularly. Out of the 219 patients, the commonest affected site was tongue (17.4%) followed by the palate (12.3%), while well-differentiated squamous cell carcinoma (46.6%) had the highest frequency. One hundred and twenty-three patients (56.2%) had lymph node involvement, while 15 (6.8%) had distant metastases. Radiotherapy was used in 57.5% of patients. Conclusion: The male/female ratio in our data was consistent with previous studies from East Africa, but different with some other parts of the world.Résumé Introduction : Le carcinome épidermoïde de la tête et du cou est le septième cancer, par ordre de fréquence, dans le monde, mais sa prévalence dans les pays africains est deux à quatre fois plus élevée que dans les pays développés. Malgré l'amélioration des techniques chirurgicales, de la chimiothérapie et de la radiothérapie, le taux de survie moyen à cinq ans reste l'un des plus faibles parmi les principaux cancers, ce qui justifie les études pouvant contribuer à la mise au point de stratégies de prévention. Buts de l'étude : Cette étude avait pour but de comparer les caractéristiques épidémiologiques, cliniques et histologiques de 219 patients atteints de carcinome épidermoïde de la tête et du cou, vus à l'hôpital national de Mulago, en Ouganda. Résultats et discussion : L'âge moyen des patients était de 58,87 ± 16,29 ans, avec un ratio hommes/femmes de 1,3. Sur les 159 patients dont on connaissait les antécédents en matière de tabagisme, 66 % se déclaraient fumeurs et 63,5 % consommaient régulièrement de l'alcool. Sur l'ensemble des 219 patients, les sites les plus fréquemment touchés étaient la langue (17,4 %) et le palais (12,3 %), la forme histologique principale étant un carcinome épidermoïde bien différencié (46,6 %). Cent vingt-trois patients (56,2 %) présentaient une atteinte ganglionnaire, et 15 (6,8 %) des métastases. La radiothérapie a été utilisée chez 57,5 % des patients. Conclusion : Le ratio hommes/femmes dans nos données est comparable à celui des précédentes études en Afrique de l'Est, mais différent de celui rapporté dans d'autres parties du monde.
