TL;DR: The present review showed that the BNCR yields internationally comparable data that are reasonably accurate, timely, and close to complete, especially in recent years, a prerequisite for the BND to expand its role to more areas of cancer control.

TL;DR: Although the prevalence of O. viverrini infection over a 14-year period has decreased, unhealthy lifestyle was common with smoking and alcohol consumption being associated with increased chances of infection, emphasising the double burden of disease which developing countries are facing.
Abstract: Background: Liver fluke infection caused by the parasite Opisthorchis viverrini (O. viverrini), a human carcinogen, is endemic in north-eastern Thailand and remains a major health problem. Objectives: The objectives of the study were to (1) resurvey the prevalence of O. viverrini infection in a field site from the Khon Kaen Cohort Study (in newly recruited subjects as well as previous cohort subjects surveyed in 1992); (2) investigate how subjects’ lifestyle habits and their exposure to health promotion initiatives influence changes in prevalence of O. viverrini infection. Materials and Methods: The prevalence of O. viverrini infection in the cohort subjects (as well as new subjects) was investigated using faecal egg counts. Information on demographic factors, lifestyle and awareness of health promotion initiatives were obtained through questionnaires. Results: O. viverrini infection rates in the same individuals of the cohort were lower in 2006 than in 1992. Also, by studying the period effect, the current 35-44 year olds had a 12.4% (95% CI 3.9% to 20.9%) lower prevalence of O. viverrini infection than the 35-44 year olds in 1992 (24.2% versus 11.8%). Lifestyle choices showed that smoking and alcohol consumption were associated with an increased chance of acquiring O. viverrini infection with adjusted odds ratios of 10.1 (95%CI 2.4-41.6) and 5.3 (95%CI 1.2-23.0), respectively. Conclusions: Our study has demonstrated that although the prevalence of O. viverrini infection over a 14-year period has decreased, unhealthy lifestyle was common with smoking and alcohol consumption being associated with increased chances of infection, emphasising the double burden of disease which developing countries are facing.

TL;DR: Health-related quality-of-life scores among CCA patients changed over time and were related to age at recruitment and use of alternative medicine, which showed that patients who were 60 to 69 years old had higher HRQOL scores than did younger patients.
Abstract: BACKGROUND Cholangiocarcinoma (CCA) remains a major health problem and causes high mortality in Northeastern Thailand. Patients with CCA have a poor prognosis, and little is known about their health-related quality of life (HRQOL) and its determinants. OBJECTIVE The objective of this study was to investigate factors affecting HRQOL and its changes over time among CCA patients. METHODS Two hundred thirty-seven patients with CCA were recruited during a 6-month period in 2011 in 5 tertiary hospitals in 4 provinces of northeastern Thailand. Health-related quality of life after diagnosis of CCA was measured by the Functional Assessment of Cancer Therapy-Hepatobiliary questionnaire (Thai version 4). The HRQOL score of CCA patients at different times after diagnosis was compared by repeated-measures analysis of variance. Generalized estimating equation was used to identify factors affecting HRQOL among CCA patients. RESULTS Of 237 eligible patients registered, 99 confirmed cases completed follow-up at 2 months. Overall HRQOL varied over time, with the score at baseline being significantly lower than 1 and 2 months later. An adjusted analysis showed that patients who were 60 to 69 years old had higher HRQOL scores than did younger patients. Patients using alternative medicine had lower HRQOL scores than did those who did not. CONCLUSIONS Health-related quality-of-life scores among CCA patients changed over time and were related to age at recruitment and use of alternative medicine. IMPLICATIONS FOR PRACTICE Healthcare providers should carefully communicate about the diagnosis and its implications. Patients with CCA, especially younger patients and those who have used traditional medicine, may benefit from counseling and help with mobilizing family and social support.
