Data from 1,916 cases of oral neoplasms occurring in the Sudan in a 16-year period, from January 1970 to December 1985, were retrieved and analysed. The study revealed a relatively high frequency of oral neoplasms in comparison with neighbouring countries. In this study, squamous-cell carcinoma was the most common oral malignancy (66.5%), followed by tumours of the salivary gland (14.7%), neoplasms of nonodontogenic and non-epithelial origin (9.6%) and odontogenic neoplasms (8.6%). Men had a higher frequency than women. The older age group of both genders showed a relatively high frequency of squamous-cell carcinoma. Among northern Sudanese there was a high rate of squamous-cell carcinoma, while southern Sudanese showed a high rate of odontogenic and salivary-gland neoplasms. The use of toombak has been stated to play a major role in the aetiology of oral squamous-cell carcinoma in the Sudan, and is suspected to be associated with neoplasms of the salivary glands.
检索并分析了1970年1月至1985年12月这16年间苏丹发生的1916例口腔肿瘤病例的数据。该研究显示，与邻国相比，苏丹口腔肿瘤的发病率相对较高。在这项研究中，鳞状细胞癌是最常见的口腔恶性肿瘤（66.5%），其次是唾液腺肿瘤（14.7%）、非牙源性和非上皮源性肿瘤（9.6%）以及牙源性肿瘤（8.6%）。男性的发病率高于女性。两个性别的老年组鳞状细胞癌发病率相对较高。在苏丹北部，鳞状细胞癌的发病率较高，而苏丹南部则显示出牙源性和唾液腺肿瘤的发病率较高。据指出，使用图姆巴克在苏丹口腔鳞状细胞癌的病因中起主要作用，并且怀疑与唾液腺肿瘤有关。
