RESUMO

INTRODUCTION: This systematic review study investigated the cost-effectiveness of stereotactic radiotherapy (SRT) and stereotactic radiosurgery (SRS) for treatment of various types of cancers. METHODS: PubMed, Scopus, and Web of Science were searched from 30 December 1990 to 1 January 2023. The entered studies were screened in accordance with the inclusion criteria. The inclusion criteria encompassed all types of economic evaluation studies that investigated SRT/SRS technologies in the treatment of various cancers. RESULTS: A total of 47 articles were included in the review. The findings suggest that the use of Linear accelerator technology for the treatment of lung cancer (8 out of 12 studies) and prostate cancer (4 out of 5 studies) was a cost-effective strategy. Linear accelerator was found to be cost-effective in the treatment of liver metastases and liver cancer (2 out of 5 studies). All of the included studies that used Gamma Knife technology in brain metastases reported Gamma-Knife was a cost-effective treatment. Furthermore, in the treatment of prostate and liver cancer, proton therapy was identified as a cost-effective option than other treatments. CONCLUSIONS: This study confirms that SRT/SRS is a cost-effective procedure for the treatment of various types of cancers. Therefore, it is recommended to use SRT/SRS technology for optimal use of resources.

RESUMO

Importance: Lip, oral, and pharyngeal cancers are important contributors to cancer burden worldwide, and a comprehensive evaluation of their burden globally, regionally, and nationally is crucial for effective policy planning. Objective: To analyze the total and risk-attributable burden of lip and oral cavity cancer (LOC) and other pharyngeal cancer (OPC) for 204 countries and territories and by Socio-demographic Index (SDI) using 2019 Global Burden of Diseases, Injuries, and Risk Factors (GBD) Study estimates. Evidence Review: The incidence, mortality, and disability-adjusted life years (DALYs) due to LOC and OPC from 1990 to 2019 were estimated using GBD 2019 methods. The GBD 2019 comparative risk assessment framework was used to estimate the proportion of deaths and DALYs for LOC and OPC attributable to smoking, tobacco, and alcohol consumption in 2019. Findings: In 2019, 370 000 (95% uncertainty interval [UI], 338 000-401 000) cases and 199 000 (95% UI, 181 000-217 000) deaths for LOC and 167 000 (95% UI, 153 000-180 000) cases and 114 000 (95% UI, 103 000-126 000) deaths for OPC were estimated to occur globally, contributing 5.5 million (95% UI, 5.0-6.0 million) and 3.2 million (95% UI, 2.9-3.6 million) DALYs, respectively. From 1990 to 2019, low-middle and low SDI regions consistently showed the highest age-standardized mortality rates due to LOC and OPC, while the high SDI strata exhibited age-standardized incidence rates decreasing for LOC and increasing for OPC. Globally in 2019, smoking had the greatest contribution to risk-attributable OPC deaths for both sexes (55.8% [95% UI, 49.2%-62.0%] of all OPC deaths in male individuals and 17.4% [95% UI, 13.8%-21.2%] of all OPC deaths in female individuals). Smoking and alcohol both contributed to substantial LOC deaths globally among male individuals (42.3% [95% UI, 35.2%-48.6%] and 40.2% [95% UI, 33.3%-46.8%] of all risk-attributable cancer deaths, respectively), while chewing tobacco contributed to the greatest attributable LOC deaths among female individuals (27.6% [95% UI, 21.5%-33.8%]), driven by high risk-attributable burden in South and Southeast Asia. Conclusions and Relevance: In this systematic analysis, disparities in LOC and OPC burden existed across the SDI spectrum, and a considerable percentage of burden was attributable to tobacco and alcohol use. These estimates can contribute to an understanding of the distribution and disparities in LOC and OPC burden globally and support cancer control planning efforts.

RESUMO

PURPOSE: This study aimed to systematically review and critically appraise cost-effectiveness studies on Brentuximab vedotin (BV) in patients with Hodgkin lymphoma (HL). METHODS: The PubMed, Scopus, Web of Science core collection, and Embase databases were searched until July 3, 2022. We included published full economic evaluation studies on BV for treating patients with HL. The methodological quality of the studies was assessed using the Quality of Health Economic Studies (QHES) checklist. Meanwhile, we used qualitative synthesis to analyze the findings. We converted the incremental cost-effectiveness ratios (ICERs) to the value of the US dollar in 2022. RESULTS: Eight economic evaluations met the study's inclusion criteria. The results of three studies that compared BV plus doxorubicin, vinblastine, and dacarbazine (BV + AVD) front-line therapy with doxorubicin, bleomycin, vincristine, and dacarbazine (ABVD) showed that BV is unlikely to be cost-effective as a front-line treatment in patients advanced stage (III or IV) HL. Four studies investigated the cost-effectiveness of BV in patients with relapsed or refractory (R/R) HL after autologous stem cell transplantation (ASCT). BV was not cost-effective in the reviewed studies at accepted thresholds. In addition, the adjusted ICERs ranged from $65,382 to $374,896 per quality-adjusted life-year (QALY). The key drivers of cost-effectiveness were medication costs, hazard ratio for BV, and utilities. CONCLUSION: Available economic evaluations show that using BV as front-line treatment or consolidation therapy is not cost-effective based on specific ICER thresholds for patients with HL or R/R HL. To decide on this orphan drug, we should consider other factors such as existence of alternative treatment options, clinical benefits, and disease burden.

RESUMO

PURPOSE: This aim of this study was to conduct a systematic review of economic evaluations comparing lenvatinib to other vascular endothelial growth factor (VEGF) inhibitors and other treatment options in the management of unresectable hepatocellular carcinoma (uHCC). METHODS: A comprehensive literature search was conducted using highly sensitive search syntax. The titles and abstracts of all records were studied and screened to identify eligible economic evaluations. To enable comparison across different countries, the results of economic evaluations make it possible to compare, the costs and ICER of all studies were converted into 2022 US dollars, and a 3% annual increase for inflation was applied. The quality of the studies was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. This study is conducted and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. RESULTS: Lenvatinib was found to be cost-effective (ICER = dominant) compared to most drugs in the included studies, except in studies where it was compared with donafenib or when the price of sorafenib was significantly discounted (e.g., with a 90% discount, the value of ICER was + 104,669 USD). CONCLUSION: Lenvatinib was generally cost-effective in most studies, but not compared to donafenib or sorafenib (if the price sorafenib was significantly discounted).

RESUMO

BACKGROUND: With the advent of new technologies, the demand for non-invasive and effective procedures to treat skin laxity has increased. In this research, we aimed to review studies conducted on the safety and effectiveness of endodermal radiofrequency (ER) for skin rejuvenation. METHODS: We searched the databases of Embase, PubMed, Scopus, and Google Scholar from 2000 to 2020 to conduct a systematic review based on the PRISMA statement. Screening of titles, abstracts, and full-text articles was performed independently by two reviewers according to inclusion and exclusion criteria. RESULTS: This study showed that ER resulted in improvement in wrinkles and sagging, reduction of fat, tightening of skin of the face, neck, and jawline, improvement in skin elasticity, pigmentation, contouring of the body, and epidermal thickness decrease. ER technology leads to a significant and satisfactory improvement in skin rejuvenation, lower contouring of skin of the face and neck, as well as patients' satisfaction. Side effects of ER are temporary, and usually disappear spontaneously after a few days to one month. CONCLUSION: Cosmetic services providers can use this effective and safe technology to treat skin laxity and skin rejuvenation as a substitute for surgery.

RESUMO

BACKGROUND: Human immunodeficiency virus and acquired immune deficiency syndrome (HIV/AIDS) is still among the leading causes of disease burden and mortality in sub-Saharan Africa (SSA), and the world is not on track to meet targets set for ending the epidemic by the Joint United Nations Programme on HIV/AIDS (UNAIDS) and the United Nations Sustainable Development Goals (SDGs). Precise HIV burden information is critical for effective geographic and epidemiological targeting of prevention and treatment interventions. Age- and sex-specific HIV prevalence estimates are widely available at the national level, and region-wide local estimates were recently published for adults overall. We add further dimensionality to previous analyses by estimating HIV prevalence at local scales, stratified into sex-specific 5-year age groups for adults ages 15-59 years across SSA. METHODS: We analyzed data from 91 seroprevalence surveys and sentinel surveillance among antenatal care clinic (ANC) attendees using model-based geostatistical methods to produce estimates of HIV prevalence across 43 countries in SSA, from years 2000 to 2018, at a 5 × 5-km resolution and presented among second administrative level (typically districts or counties) units. RESULTS: We found substantial variation in HIV prevalence across localities, ages, and sexes that have been masked in earlier analyses. Within-country variation in prevalence in 2018 was a median 3.5 times greater across ages and sexes, compared to for all adults combined. We note large within-district prevalence differences between age groups: for men, 50% of districts displayed at least a 14-fold difference between age groups with the highest and lowest prevalence, and at least a 9-fold difference for women. Prevalence trends also varied over time; between 2000 and 2018, 70% of all districts saw a reduction in prevalence greater than five percentage points in at least one sex and age group. Meanwhile, over 30% of all districts saw at least a five percentage point prevalence increase in one or more sex and age group. CONCLUSIONS: As the HIV epidemic persists and evolves in SSA, geographic and demographic shifts in prevention and treatment efforts are necessary. These estimates offer epidemiologically informative detail to better guide more targeted interventions, vital for combating HIV in SSA.

RESUMO

OBJECTIVES: This study aimed to systematically review the cost-effectiveness studies of multiparametric magnetic resonance imaging (mpMRI)-guided biopsy (MRGB) compared with systematic transrectal ultrasonography (TRUS)-guided biopsy for diagnosing prostate cancer (PCa). METHODS: PubMed, Web of Science core collection, Embase and Scopus, and reference lists of the included studies were searched with no date and language restrictions through January 2020 for full economic evaluation studies (cost-effectiveness, cost-utility analysis, cost-benefit analysis) that assessed mpMRI and MRGB compared with systematic TRUS-guided biopsy or other sequential biopsy strategies in men undergoing initial prostate biopsy or men with previous negative prostate biopsy, with clinical suspicion of PCa based on abnormal prostate-specific antigen or digital rectal examination increase or both. Data were tabulated and analyzed using narrative synthesis. The reporting quality of included studies was assessed using the Consolidated Health Economic Evaluation Reporting Standards checklist. This systematic review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. RESULTS: Finally, 9 studies were included. All studies were conducted in high-income countries. All studies found that mpMRI and MRGB was cost-effective in the initial and before repeat biopsy in men with previous negative biopsy. The cognitive-targeted TRUS-guided biopsy was cost-effective in the initial biopsy (dominant or cost-effective at willingness-to-pay threshold of the countries); it was not evaluated for repeat biopsy in men. The direct in-bore magnetic resonance imaging (MRI)-guided biopsy was cost-effective for the initial biopsy (€323 per quality-adjusted life-year gained). The superiority of one of the targeted biopsy approaches (fusion, cognitive, or in-bore) over other approaches has not yet been established. CONCLUSIONS: This study showed that pre-TRUS-guided biopsy MRI is more cost-effective than TRUS-guided biopsy alone. Furthermore, the use of MRI-ultrasound fusion targeted biopsy in the diagnosis of PCa in the initial biopsy and repeat biopsy and cognitive-targeted TRUS-guided biopsy in the initial biopsy is cost-effective.

RESUMO

BACKGROUND: The prevalence of tobacco use, especially hookah, has increased in Iran In recent years, particularly among young people and women, and the age of onset of use has decreased. Tobacco use is the fourth leading risk factor for non-communicable diseases in Iran. These issues cause concerns in the country and led to the present study on tobacco control agenda-setting in Iran over a 30-year timeframe. METHODS: We conducted this retrospective analytical study to investigate process analysis in Iran using Kingdon's multiple-streams framework (MSF). We collected the data using semi-structured interviews with key informants (n = 36) and reviewing policy documents (n > 100). Then, we analyzed the policy documents and in-depth interviews using the document and framework analysis method. We used MAXQDA 11 software to classify and analyze the data. RESULTS: Iran's accession to the Framework Convention on Tobacco Control (FCTC) opened a window of opportunity for tobacco control. The policy window opens when all three streams have already been developed. The adoption of the comprehensive law on the national control and campaign against tobacco in the Islamic Consultative Assembly in 2006 is a turning point in tobacco control activities in Iran. CONCLUSIONS: The tobacco control agenda-setting process in Iran was broadly consistent with MSF. The FCTC strengthened the comprehensive plan for national control of tobacco as a policy stream. However, there are several challenges in developing effective policies for tobacco control in the Iranian setting.

RESUMO

PURPOSE: The main purpose of prescribing oral anticoagulants in patients undergoing total knee and total hip replacement surgery is to prevent venous thromboembolism (VTE). The present study aimed to summarize evidence from economic evaluations regarding new oral anticoagulants (NOACs) used in VTE prophylaxis after joint replacement surgery. METHODS: To obtain relevant literature on economic evaluations of NOACs used in the prevention of VTE following joint replacement surgery, we searched the Cochrane Library, PubMed, Web of Science, Embase, and Scopus, as well as specialized economic evaluation databases, for articles published from January 2008 to December 2019. Next, 2 reviewers screened the titles and abstracts of studies, extracted data from the full-text articles, and assessed the quality of the methodologies using the Quality of Health Economic Studies checklist. FINDINGS: Twenty-eight studies of economic evaluations met the inclusion criteria of the research. The quality assessment showed that 20 articles had scores within the range of 75 to 100 (high quality), and 9 studies had scores within the range of 50 to 74 (moderate quality). All of the identified studies had been carried out based on modelling, and 23 studies used decision trees to model acute events after surgery. In addition, 20 studies utilized a Markov model to capture long-term complications of VTE. The results showed that rivaroxaban was more cost-effective than apixaban and dabigatran from a perspective of the health care system in the prevention of VTE after total knee and total hip replacement surgery. In addition, apixaban was associated with a lower risk for bleeding events than other NOACs, making it the most cost-effective NOAC from the perspective of the payer. IMPLICATIONS: The results suggest that NOACs are cost-effective alternatives to low-molecular-weight heparins. Rivaroxaban and dabigatran were assessed as the most and least cost-effective prophylaxis options, respectively, after joint replacement surgery for the prevention of VTE. It is recommended that future research be conducted on economic evaluations of edoxaban.

RESUMO

BACKGROUND: Nonrheumatic valvular diseases are common; however, no studies have estimated their global or national burden. As part of the Global Burden of Disease Study 2017, mortality, prevalence, and disability-adjusted life-years (DALYs) for calcific aortic valve disease (CAVD), degenerative mitral valve disease, and other nonrheumatic valvular diseases were estimated for 195 countries and territories from 1990 to 2017. METHODS: Vital registration data, epidemiologic survey data, and administrative hospital data were used to estimate disease burden using the Global Burden of Disease Study modeling framework, which ensures comparability across locations. Geospatial statistical methods were used to estimate disease for all countries, because data on nonrheumatic valvular diseases are extremely limited for some regions of the world, such as Sub-Saharan Africa and South Asia. Results accounted for estimated level of disease severity as well as the estimated availability of valve repair or replacement procedures. DALYs and other measures of health-related burden were generated for both sexes and each 5-year age group, location, and year from 1990 to 2017. RESULTS: Globally, CAVD and degenerative mitral valve disease caused 102 700 (95% uncertainty interval [UI], 82 700-107 900) and 35 700 (95% UI, 30 500-42 500) deaths, and 12.6 million (95% UI, 11.4 million-13.8 million) and 18.1 million (95% UI, 17.6 million-18.6 million) prevalent cases existed in 2017, respectively. A total of 2.5 million (95% UI, 2.3 million-2.8 million) DALYs were estimated as caused by nonrheumatic valvular diseases globally, representing 0.10% (95% UI, 0.09%-0.11%) of total lost health from all diseases in 2017. The number of DALYs increased for CAVD and degenerative mitral valve disease between 1990 and 2017 by 101% (95% UI, 79%-117%) and 35% (95% UI, 23%-47%), respectively. There is significant geographic variation in the prevalence, mortality rate, and overall burden of these diseases, with highest age-standardized DALY rates of CAVD estimated for high-income countries. CONCLUSIONS: These global and national estimates demonstrate that CAVD and degenerative mitral valve disease are important causes of disease burden among older adults. Efforts to clarify modifiable risk factors and improve access to valve interventions are necessary if progress is to be made toward reducing, and eventually eliminating, the burden of these highly treatable diseases.

RESUMO

Background: Breast-conserving surgery (BCS) is the recommended treatment for early breast cancer. After BCS. Whole-breast external beam radiotherapy (WB-EBRT) is the standard of care. A possible alternative to post-operative WB-EBRT is intraoperative radiation therapy (IORT). The objectives of this systematic review were to analyses the cost-effectiveness of IORT versus EBRT for early-stage breast cancer and to assess the reporting quality of the included studies to inform future studies. Methods: A systematic literature search was carried out in five main databases (PubMed, Scopus, Embase, Cochrane library, and Web of Science) to identify original studies published to June 25, 2020. We included all full economic evaluation studies (cost-effectiveness analysis (CEA), cost-utility analysis (CUA), and cost-benefit analysis (CBA), Model-based or trial-based) that assessed and compared IORT and EBRT in patients with early operable breast cancer. Study outcomes included cost per life-years gained or cost per quality-adjusted life-years (QALYs) gained or in monetary units or incremental cost-effectiveness ratio (ICER). The quality of the included articles was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. This review has been conducted and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Results: Of 1155 studies identified, eight studies met the inclusion criteria. In four studies, IORT was associated with lower costs and higher effectiveness than EBRT. In three studies, the dominant option was EBRT. In these studies, IORT also had lower costs and lower effectiveness than EBRT. Existing evidence suggests that IORT can be a cost-effective alternative to early breast cancer treatment by reducing therapeutic costs. Variables of cost-effectiveness were treatment costs, health state utilities, local and distant recurrence rates, and the probabilities of metastasis after treatment, recurrent cancer and death for both IORT and EBRT. The reporting quality of the included studies was "high" in five, "medium quality" in one and "low" in two studies. Conclusion: Current evidence is sparse, and the number of studies was small but this evidence proposes that IORT can be a potential cost-saving strategy to the health systems for the adjuvant treatment of early breast cancer if the technology was carried out routinely in eligible patients. However, these results should be interpreted with caution because of the heterogeneity of studies and possible publication bias.

RESUMO

Background: Tobacco consumption is still considered as the first preventable cause of death in the world. In order to influence tobacco policy process, researchers and policymakers must use frameworks of policy-making to understand the process to provide them insights for influence the process. This systematic review aims to review the application of policy analysis frameworks in the field of tobacco control. Methods: A systematic search for articles was performed using four databases (Ovid Medline, Scopus, Cochrane Library, and PubMed) up to December 19, 2016. The articles were selected based on inclusion and exclusion criteria. All research studies focusing on tobacco policy and on one or more specified frameworks of policy analysis included in this study. Finally, thematic analysis was used to synthesize the findings. Results: 17 studies based on eligibility criteria were included in this study. The findings of this study showed that most of the studies were in North America, published in the Health journals, conducted to analyze the national and state policies, focused on analyzing agenda-setting phase. Multiple streams model was the most widely used framework within the literature. Few studies had used advocacy coalition framework. From the three agenda setting frameworks and theories (MSF, PEF, ACF), the ACF framework is the most detailed framework in terms of elements and factors affecting the dynamics of political sub-system the reasons for models selection and suitability for the study was noted only in a small number of studies. The results of this study showed underuse and the incomplete or improper use of policy analysis models and frameworks in the field of tobacco research. Conclusion: The study showed that a number of theories and frameworks have been used but their use was limited and have significant methodological weaknesses.

RESUMO

Background: Telemedicine is an expanded term in health information technology that comprises procedures for transmitting medical information electronically to improve patients' health status. The objective of this research is to evaluate the cost-effectiveness of telemedicine interventions in various specialty areas. Methods: The Cochrane Library and Centre for Review and Dissemination were searched up to February 2013 using Mesh. Studies that compared any kind of telemedicine with any other routine care technique and used cost per health utility unit's outcomes were included. Results: Twenty-one articles were included. According to the included studies, it seems that using telemedicine in cardiology can be effective and cost-effective enough but pre-hospital telemedicine diagnostics program are likely to have little impact on acute myocardial infarction fatality. In pulmonary, telemedicine can be a cost-effective strategy for delivering outpatient pulmonary care to rural populations which have limited access to specialized services, but telemedicine is not cost- effective in asthma and airways cancer. In ophthalmology, especially in the diagnosis of diabetic retinopathy, the use of telemedicine is a cost-effective tool. In dermatology, telemedicine is not cost-effective enough in comparison of conventional cares. In other fields such as physical activity and diet, eating disorder, tele-ICU, psychotherapy for depression and telemedicine on ships, telemedicine can be used as a cost-effective tool for treatments or cares. Conclusion: Most of the included studies confirmed that telemedicine is cost-effective for applying in major medical fields such as cardiology; but in dermatology, papers could not confirm the positive capability of telemedicine.

RESUMO

BACKGROUND: Image-guided radiotherapy used multiple imaging during the radiation therapy course to improve the precision and accuracy of health care provider's treatment. OBJECTIVES: This study aims to assess the safety, effectiveness and economic aspects of image-guided radiation therapy for decision-making about this technology in Iran. METHODS: In this study, the most important medical databases such as PubMed and Cochrane Library were searched until November 2014. The systematic reviews, health technology assessment reports and economic evaluation studies were included. The results of included studies were analyzed via the thematic synthesis. RESULTS: Seven articles were included in the study. The results showed that image-guided radiation therapy, regardless of the imaging technique used in it, is associated with no major toxicity and has the potential to reduce the symptoms of poisoning. Using image-guided radiation therapy for prostate cancer resulted in substantial improvement in the quality of the received dose and optimal therapeutic dose of radiation to the targeted tumor while the radiation dose to the surrounding healthy tissues was minimal. Additionally, image-guided radiation therapy facilitated the diagnosis and management of exception deviations, including immediate changes and gross errors, weight loss, significant limbs deformity, systematic changes in the internal organs and changes in respiratory movements. Usage of image-guided radiation therapy for prostate cancer was associated with increased costs. CONCLUSION: Current available evidence suggests that the image-guided radiation therapy can reduce the amount of radiation to healthy tissue around the tumor and the toxicity associated with it. This can enhance the safe dose of radiation to the tumor and increase the likelihood of destruction of tumor. The current level of evidence required conducting further studies on the costs and effectiveness of this technology compared with conventional technology.

RESUMO

BACKGROUND: Intra-operative radiation therapy (IORT) is the transfer of a single large radiation dose to the tumor bed during surgery with the final goal of improving regional tumor control. This study aimed to investigate the safety, effectiveness and economic evaluation of intra-operative radiation therapy. METHODS: The scientific literature was searched in the main biomedical databases (Centre for Reviews and Dissemination, Cochrane Library and PubMed) up to March 2014. Two independent reviewers selected the papers based on pre-established inclusion criteria, with any disagreements being resolved by consensus. Data were then extracted and summarized in a structured form. RESULTS from studies were analyzed and discussed within a descriptive synthesis. RESULTS: Sixteen studies met the inclusion criteria. It seems that outcomes from using intraoperative radiation therapy can be considered in various kinds of cancers like breast, pancreatic and colorectal cancers. The application of this method may provide significant survival increase only for colorectal cancer, but this increase was not significant for other types of cancer. This technology had low complications; and it is relatively safe. Using intra-operative radiation therapy could potentially be accounted as a cost-effective strategy for controlling and managing breast cancer. CONCLUSION: According to the existing evidences, that are the highest medical evidences for using intra-operative radiation therapy, one can generally conclude that intra-operative radiation therapy is considered as a relatively safe and cost-effective method for managing early-stage breast cancer and it can significantly increase the survival of patients with colorectal cancer. Also, the results of this study have policy implications with respect to the reimbursement of this technology.
