ALTHOUGH there is a voluminous amount of literature on salivary gland tumours, investigations based on significantly large number of cases have been relatively few. From this part of the world, reliable information is even less readily obtainable. In the present series, 670 salivary gland tumours are available for study. It is hoped that this large material may furnish additional data on these tumours and on those aspects which are peculiar to Malaya in particular.
MATERIALS AND METHODSThis study is based on the material collected in the Pathology Division of the Institute for Medical Research, Kuala Lumpur, over the eighteen year period from 1948-1965 inclusive. The material comprised 670 cases of salivary gland tumours.All histological sections were re-examined. Only the brief clinical histories which accompanied the specimens were available. These were studied in relation to the different histological types.
RESULTS
FrequencyThe State of Selangor, which contains the capital of Malaya, has the best records and medical facilities. The standardised rate for salivary gland tumours computed in this state is therefore taken as a representative example.In the year 1965, the end-of-year population figure is given as 694,064 males and 645,078 females in Selangor. During this year, 14 new cases of salivary gland tumours were seen, 9 of which were in males and 5 in females. This gives an incidence rate as follows: Males:
