ReviewPublication 2008Modeling Cervical Cancer Prevention in Developed Countries
Decision-analytic models are increasingly developed to simulate disease burden and interventions in different settings in …
Decision-analytic models are increasingly developed to simulate disease burden and interventions in different settings in order to evaluate the benefits and cost-effectiveness of primary and secondary interventions. This article is a review of mathematical models that have been used to evaluate HPV vaccination in the context of developed countries with existing screening programs. Despite variations in model assumptions and uncertainty in existing data, pre-adolescent vaccination of females in the setting of current screening practices has…

ArticlePublication 2008Mathematical Models of Cervical Cancer Prevention in Latin America and the Caribbean
This article reports on a model-based approach estimated averted cervical cancer cases and deaths, disability-adjusted …
This article reports on a model-based approach estimated averted cervical cancer cases and deaths, disability-adjusted life years (DALYs) and incremental cost-effectiveness ratios (I$/DALY averted) for human papillomavirus (HPV) vaccination of young adolescent girls using population and epidemiologic data for 33 countries in Latin America and the Caribbean (LAC). The authors found that an absolute reduction in lifetime cancer risk varied between countries, depending on incidence, proportion attributable to HPV-16 and 18, and population age-structure; for…

ArticlePublication 2008Development of an Empirically Calibrated Model of Gastric Cancer in Two High-Risk Countries
This paper presents an empirically calibrated mathematical model of gastric cancer and H. pylori in …
This paper presents an empirically calibrated mathematical model of gastric cancer and H. pylori in China and Colombia to provide qualitative insight into the cost-effectiveness of gastric cancer prevention strategies. Despite studies that have established the relationship between Helicobacter pylori and gastric cancer and H. pylori treatment reducing cancer incidence among individuals without preexisting precancerous lesions, screening for H. pylori is still being debated. The authors synthesized…!--?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" /-->

ArticlePublication 2007Including Boys in an HPV Vaccination Program: A CEA in a Low-Resource Setting
This paper looks at the cost-effectiveness of including boys vs girls alone in a pre-adolescent vaccination …
This paper looks at the cost-effectiveness of including boys vs girls alone in a pre-adolescent vaccination program against human papillomavirus (HPV) types 16 and 18 in Brazil. Using demographic, epidemiological, and cancer data from Brazil, the authors developed a dynamic transmission model of HPV infection between males and females. Model-projected reductions in HPV incidence under different vaccination scenarios were applied to a stochastic model of cervical carcinogenesis to project lifetime costs and benefits. They found that at 90%…

ArticlePublication 2007Modeling HPV and Cervical Cancer in the U.S. for Analyses of Screening and Vaccination
This paper discusses a model of human papillomavirus (HPV) and cervical cancer that incorporates uncertainty …
This paper discusses a model of human papillomavirus (HPV) and cervical cancer that incorporates uncertainty about the natural history of disease that was used to provide quantitative insight into U.S. policy choices for cervical cancer prevention. The authors developed a stochastic microsimulation of cervical cancer that distinguishes different HPV types by their incidence, clearance, persistence, and progression. For each set of sampled input parameters, likelihood-based goodness-of-fit (GOF) scores were computed based on comparisons between model-predicted…

ArticlePublication 2007Multiparameter Calibration of a Natural History Model of Cervical Cancer
This paper presents a two-step approach to model calibration of a comprehensive natural history model …
This paper presents a two-step approach to model calibration of a comprehensive natural history model of human papillomavirus (HPV) and cervical cancer. Using primary epidemiologic data from a longitudinal study of women in Brazil, a plausible range for each input parameter was identified that would produce model output within the 95% confidence intervals of the data. The authors then performed a simultaneous search over all input parameters to identify parameter sets that produced output consistent…

ArticlePublication 2024Hepatitis C Elimination in Rwanda: Progress, Feasibility, Economic Evaluation
This study evaluates the impact of Rwanda's national program launched in 2018 to eliminate hepatitis …
This study evaluates the impact of Rwanda's national program launched in 2018 to eliminate hepatitis C virus (HCV) and identifies strategies to achieve World Health Organization (WHO) elimination goals by 2030. Employing a microsimulation model spanning 2015 to 2050, the analysis assesses HCV epidemic trends, prevalence, mortality, and total care costs under various scenarios. Results show that between 2018 and 2022, over 7 million people were screened and 60,000 treated, projecting Rwanda's potential achievement of…

ArticlePublication 2022Cost-Effectiveness of Masked Hypertension Screening and Treatment
The study assessed the health and economic outcomes of screening and treating masked hypertension in …
The study assessed the health and economic outcomes of screening and treating masked hypertension in U.S. adults using the Cardiovascular Disease (CVD) Policy Model, a microsimulation model. The model simulated 100,000 adults suspected of having masked hypertension (office blood pressure [BP] of 120–129/<80 mm Hg, not on antihypertensive medications, and without a history of CVD). Interventions included: usual care alone, usual care with ambulatory BP monitoring (ABPM), and usual care with home BP monitoring (HBPM).…

ArticlePublication 2019Global Childhood Cancer Survival Estimates and Priority-Setting: A Simulation-Based Analysis
This modelling study provides estimates of global childhood cancer survival, accounting for the impact of …
This modelling study provides estimates of global childhood cancer survival, accounting for the impact of multiple factors that affect cancer outcomes in children. The authors developed a microsimulation model to simulate childhood cancer survival for 200 countries/territories, accounting for clinical and epidemiologic factors, including country-specific treatment variables, such as availability of chemotherapy, radiation, and surgery, and calibrated the model to empirical data from the CONCORD-2 and CONCORD-3 studies using an Approximate Bayesian Computation approach. The…
