唾液腺的恶性肿瘤在人类全部肿瘤中还不到1%,其发病率每年约为0.2人/10万人;而格陵兰地区的腮腺肿瘤中则有60%以上属恶性肿瘤,高出世界其它地区2～3倍(男性年发病率3.9/10万人,女性7.7人/10万人)。有90%发生在腮腺部位,其中90%为含有淋巴样基质的未分化癌。居住在加拿大的爱斯基摩人的唾液腺的恶性肿瘤的发病率比估计的要高30多倍。其中大多数为含有淋巴样基质的未分化癌,在报告的病例中3/4为格陵兰土著人,北美爱斯基摩人和中国南方人(香港地区),均属蒙古人种。但是在香港人中,大唾液腺癌
Malignant tumors of salivary glands in less than 1% of all human tumors, the incidence rate of about 0.2 per 100 000 people; and parotid tumors in Greenland, more than 60% of malignant tumors, higher than the rest of the world 2 ~ 3 times (annual incidence of 3.9 / 100,000 men, 7.7 women / 100000 people). Ninety percent occur in the parotid site, of which 90% are undifferentiated cancers containing lymphoid stroma. Malignant neoplasms in the Eskimos living in Canada are over 30 times more likely than expected. Most of these were undifferentiated cancers with lymphoid stroma, of which 3/4 were indigenous to Greenland, Eskimos from North America, and Southerners from Hong Kong, all of whom were Mongoloid. But among Hong Kong people, large salivary gland cancer
