Cancer incidence and mortality in Brunei Darussalam, 2011 to 2020
Abstract
Abstract This study presents the trends of age-standardised incidence and mortality rates of common cancers in Brunei Darussalam from 2011 to 2020. All cancer cases diagnosed among Brunei Darussalam citizens and permanent residents in the period 2011 to 2020 were included in the study. De-identified data were provided by the CanReg5 based BDCR, Ministry of Health Brunei Darussalam. The annual age-standardised incidence and mortality rates per 100,000 persons were standardised by the direct method using the World Health Organization (WHO) world standard population distribution. Joinpoint regression analyses were used to study the incidence and mortality trends of cancer in Brunei Darussalam over the 2011–2020 period. Trends were expressed as average annual percent change (AAPC) over 2011 to 2020, or annual percent change (APC) for a given time period. There were a total of 6,495 new cancer cases diagnosed and 3,359 death cases recorded from 2011 to 2020, in Brunei Darussalam. The five common cancers for males were colorectal, lung and bronchus, prostate, liver, and non-Hodgkin lymphoma. Among females, the five most common cancers were breast, colorectal, lung and bronchus, corpus uteri and cervix uteri. The five leading cancer deaths for males were lung and bronchus, colorectal, liver, prostate, and stomach, while for females, the five leading cancer deaths were breast, lung and bronchus, colorectal, ovary, and cervix uteri. There was a significant increase in the incidence trend of corpus uteri (AAPC $$:13.3$$ : 13.3 ) and a significant decline in the incidence trend for cervical cancer (AAPC $$:-4.5$$ : - 4.5 ) from 2011 to 2020. There was a significant increase in the mortality trend of female breast cancer from 2011 to 2015 (APC $$:16.3$$ : 16.3 ), but the trend significantly declined from 2015 to 2020 (APC $$:-12.5$$ : - 12.5 ). We also found a significant decrease in mortality trends for stomach cancer (AAPC $$:-4.7$$ : - 4.7 ) from 2011 to 2020 for both genders combined. The burden of common cancers is expected to continue to grow with ageing population, effective public health interventions targeting high burden cancers and high-risk groups, and control of modifiable risk factors will continue to be the essential approaches in reducing cancer burden.
