在咀嚼槟榔习惯广泛传播的缅甸，口腔癌症的发生并不清楚。由于咀嚼槟榔被认为是口腔癌的重要致病因素之一，我国应对口腔癌的环境状况进行调查。我们调查了仰光和曼德勒两个癌症登记处的口腔癌症和全身癌症病例，这两个城市在缅甸都有代表性的转诊医院，我们发现口腔癌在男性中排名第六，在女性中排名第十，占全身癌症的3.5%。以男性为主，比例为2.1：1。最常见的部位是舌头，其次是上颚，这与其他有槟榔肉咀嚼习惯的国家不同。约90%的男性和44%的女性患者有超过15年的咀嚼和吸烟习惯性背景。这一结果首次揭示了缅甸可靠的口腔癌发病率，这表明长期的咀嚼和吸烟习惯是口腔癌患者的病因背景。
The occurrence of oral cancer is not clearly known in Myanmar, where betel quid chewing habits are widely spread. Since betel quid chewing has been considered to be one of the important causative factors for oral cancer, the circumstantial situation for oral cancer should be investigated in this country. We surveyed oral cancer cases as well as whole body cancers from two cancer registries from Yangon and Mandalay cities, both of which have representative referral hospitals in Myanmar, and we showed that oral cancer stood at the 6th position in males and 10th in females, contributing to 3.5% of whole body cancers. There was a male predominance with a ratio of 2.1:1. Their most frequent site was the tongue, followed by the palate, which was different from that in other countries with betel quid chewing habits. About 90% of male and 44% of female patients had habitual backgrounds of chewing and smoking for more than 15 years. The results revealed for the first time reliable oral cancer frequencies in Myanmar, suggesting that longstanding chewing and smoking habits are etiological backgrounds for oral cancer patients.
