This study aims to systematically review the studies on the cost-effectiveness of stereotactic body radiotherapy (SBRT) in the treatment of non–small-cell lung cancer (NSCLC). A systematic literature search was performed in databases from 2000 through April 2021. The search terms included 'economics,' 'cost,' 'cost effectiveness,' 'SBRT,' and all names for NSCLC. Two reviewers independently screened the titles, abstracts and full texts to determine the studies for the final sample. The quality of the included studies was assessed using the Quality of Health Economic Studies checklist. Eleven studies were identified and included in our final review. SBRT was reported to be a cost-effective (5 of 5) option compared to conventional radiotherapy, radiofrequency ablation, and best supportive care for medically inoperable, early-stage NSCLC. However, the identified studies revealed that no single treatment was found to be more cost-effective than others between SBRT and surgical interventions. The key drivers of this cost-effectiveness were the cost of the treatment, utility value, and the rate of surgical mortality. SBRT may be considered a more cost-effective strategy for medically inoperable, early-stage NSCLC. Considering the limited studies available, more related research should be conducted to further validate these results. [ABSTRACT FROM AUTHOR]

Abstract: Objective: The goal of this study was to analyze the economic benefits of introducing the 7-valent pneumococcal conjugate vaccine (PCV7) into the City Immunity Program in Shanghai. Methods: A decision-analytic model designed for pneumococcal disease and outcomes of pneumococcal infection was populated with local, age-specific incidence and cost data to estimate the expected economic benefits from vaccinating a birth cohort of 172,183 infants in Shanghai over a 1-year period using a cross-sectional approach. The analysis was assumed to occur in a year at which time the direct and indirect effects of vaccination have reached a steady state. Costs were calculated from a payer perspective and included vaccination program costs and direct medical expenditures from pneumococcal-related disease. Results: The model predicts that 112,629 cases of pneumococcal-related disease could be prevented during a given year following the introduction of the PCV7 vaccine into the City Immunity Program in Shanghai, leading to a reduction of ¥187,923,359 (US $29,067,790) in direct medical costs. Overall, the inclusion of the PCV7 vaccine is estimated to have a cost-per-life-year saved of ¥37,468 (US $5,796) and a cost-per-quality-adjusted-life-year gained of ¥41,603 (US $6,435) when both the direct and indirect effects of the vaccine resulting from herd protection are taken into account. Conclusions: Results suggest that including PCV7 into the City Immunity Program in Shanghai could be considered cost-effective under generally accepted willingness-to-pay thresholds when both the direct and indirect effects of the vaccine are considered in the analysis.
