Survival analysis of cancer patients
Majority of lung cancer patients were diagnosed in Stage 3 or 4 and overall median survival time was 6.1 months in Brunei Darussalam. Although the survival time was comparable to some developed countries, survival can be improved by early detection. Improving awareness of individuals on risk factors, early signs and symptoms, and practice of regular check up, the survival can be improved. Therefore, we are interested to assess the awareness and practice in the community. The study will involve, designing and validation of research tool, and a survey method to achieve the study objectives.
Smoking-related diseases have been the primary cause of mortality in Brunei Darussalam. Recent study showed that the prevalence of smoking in Brunei Darussalam was still high (15.2% among adult populations and 31.8% among male). It is important to understand knowledge, attitude and practice with regard to smoking among Brunei population so that effective intervention can be carried out in the future. The study will involve, designing and validation of research tool, and a survey method to achieve the study objectives.
Cancer is a leading cause of deaths in Brunei Darussalam. Using the past available data since the start of cancer registry in 2002, it will be adequate to assess the existing data and develop methods to forecast for the next 3 to 5 years. Various time-series methods will be explored to identify the best-fit model for the forecasting. Developing models, evaluating models to identify the best-fit model, and using the model to forecast will be the key steps.
