Abstract
Breast cancer is the most common cancer in Thai women with the age-standardized incidence rate of
25.6/100,000. Among mammography, clinical breast examination, and self breast examination, only mammographic
screening showed efficacy in decreasing mortality rate from breast cancer. But an organized
mammographic screening has not been established in Thailand due to lack of human resource and infrastructure.
The study aimed to evaluate the cost-utility of establishing a once-in-a-lifetime breast cancer
screening with mammography in Thai women aged 40-49 years and aged 50-59 years through decision
tress. Societal perspective was used to estimate both direct and indirect costs. Incremental cost-effectiveness
ratios (ICER) were calculated and sensitivity analysis was performed by applying probabilistic sensitivity
analysis. ICERs of establishing a once-in-a-lifetime breast cancer screening with mammography in
Thai women aged 40-49 years and 50-59 years were 1,847,481 Bath/QALY and 1,368,764 Bath/QALY,
respectively. The measure was not found to be cost-effective in Thailand.
