Notes:
A total of 805 intra-oral neoplasms was diagnosed in Chinese subjects from 1964–1982 in the University Department of Pathology, Hong Kong. Squamous cell carcinoma (SCC) totalled 502 and constituted 86% of 502 malignant tumors. Although the majority (82%) of SCC were of the well-differentiated type, the relatively poor differentiation exhibited by palatal SCC in the females, was noteworthy. There was a marked male predominance in all SCC subgrouped by anatomic site, but the sex difference declined after the 6lh decade and disappeared by the 9th decade. A significant rise in the incidence rate was observed in the decade after 1973 compared to that for 1964–72 in both male (p 〈 0.0001) and female (p 〈 0.001). It is speculated that, in the absence of improved oral hygience and dental care, changes in the smoking and drinking habits in the local Chinese are of causal importance.
