title: The spectrum of histologically diagnosed malignant neoplasms in Sabah, 1983-1988.
abstract: Malignant neoplasms diagnosed histologically in the state of Sabah during the period November 1983 to October 1988 were analysed to determine the distribution of malignant neoplasms according to site, age, sex and major ethnic groups. The five commonest malignant neoplasms in males were carcinomas of the nasopharynx, stomach, skin, lung and liver. In females the five commonest malignant neoplasms were carcinomas of the cervix uteri, breast, ovary, thyroid and skin. There was variation in these frequencies among the major ethnic groups. The most striking of these was the high frequency of nasopharyngeal carcinoma among Kadazan and Chinese males but not in males of the other indigenous groups. A significant number of patients with nasopharyngeal carcinoma was found in the younger age groups and most of the patients in the younger age groups were Kadazans. A relatively high frequency of carcinoma of the stomach, skin and liver was seen among Kadazans and other indigenous groups while carcinoma of the lung was seen relatively frequently among Chinese males. Among females carcinomas of the breast and cervix uteri were the most frequent malignant neoplasms in all the main ethnic groups. Possible reasons for these findings are discussed.
