RESUMO
Aim: To estimate the cost-effectiveness of zolbetuximab plus capecitabine/oxaliplatin (CAPOX) in CLDN18.2-positive, HER2-negative, mG/GEJ adenocarcinoma from the perspective of Chinese payers.Materials & methods: A partitioned survival model was developed to assess the costs, quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios (ICER) of zolbetuximab plus CAPOX versus placebo plus CAPOX. Sensitivity analyses were performed to test the robustness of model.Results: Zolbetuximab plus CAPOX gained an additional cost of $91,551 and an extra health benefit of 0.24 QALY over placebo plus CAPOX, producing an ICER of $388,186/QALY, which exceeded the willingness-to-pay threshold of $38,223/QALY. Sensitivity analysis shows that the model was generally robust.Conclusion: Zolbetuximab plus CAPOX would not be a cost-effective first-line treatment regimen in CLDN18.2-positive, HER2-negative, mG/GEJ adenocarcinoma in China.

BACKGROUND: Bevacizumab shows superior efficacy in cerebral radiation necrosis (CRN) therapy, but its economic burden remains heavy due to the high drug price. This study aims to evaluate the cost-effectiveness of bevacizumab for CRN treatment from the Chinese payers' perspective. METHODS: A decision tree model was developed to compare the costs and health outcomes of bevacizumab and corticosteroids for CRN therapy. Efficacy and safety data were derived from the NCT01621880 trial, which compared the effectiveness and safety of bevacizumab monotherapy with corticosteroids for CRN in nasopharyngeal cancer patients, and demonstrated that bevacizumab invoked a significantly higher response than corticosteroids (65.5% vs. 31.5%, Pâ¯< 0.001) with no significant differences in adverse events between two groups. The utility value of the "non-recurrence" status was derived from real-world data. Costs and other utility values were collected from an authoritative Chinese network database and published literature. The primary outcomes were total costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER). The uncertainty of the model was evaluated via one-way and probabilistic sensitivity analyses. RESULTS: Bevacizumab treatment added 0.12 (0.48 vs. 0.36) QALYs compared to corticosteroid therapy, along with incremental costs of $ 2010 ($ 4260 vs. $ 2160). The resultant ICER was $ 16,866/QALY, which was lower than the willingness-to-pay threshold of $ 38,223/QALY in China. The price of bevacizumab, body weight, and the utility value of recurrence status were the key influential parameters for ICER. Probabilistic sensitivity analysis revealed that the probability of bevacizumab being cost-effectiveness was 84.9%. CONCLUSION: Compared with corticosteroids, bevacizumab is an economical option for CRN treatment in China.

PURPOSE: To investigate the cost-effectiveness of lenvatinib plus pembrolizumab (LP) compared to chemotherapy as a second-line treatment for advanced endometrial cancer (EC) from the United States and Chinese payers' perspective. METHODS: In this economic evaluation, a partitioned survival model was constructed from the perspective of the United States and Chinese payers. The survival data were derived from the clinical trial (309-KEYNOTE-775), while costs and utility values were sourced from databases and published literature. Total costs, quality-adjusted life years (QALYs) and incremental cost-effectiveness ratio (ICER) were estimated. The robustness of the model was evaluated through sensitivity analyses, and price adjustment scenario analyses was also performed. RESULTS: Base-case analysis indicated that LP wouldn't be cost-effective in the United States at the WTP threshold of $200 000, with improved effectiveness of 0.75 QALYs and an additional cost of $398596.81 (ICER $531392.20). While LP was cost-effective in China, with improved effectiveness of 0.75 QALYs and an increased overall cost of $62270.44 (ICER $83016.29). Sensitivity analyses revealed that the above results were stable. The scenario analyses results indicated that LP was cost-effective in the United States when the prices of lenvatinib and pembrolizumab were simultaneously reduced by 61.95% ($26.5361/mg for lenvatinib and $19.1532/mg for pembrolizumab). CONCLUSION: LP isn't cost-effective in the patients with advanced previously treated endometrial cancer in the United States, whereas it is cost-effective in China. The evidence-based pricing strategy provided by this study could benefit decision-makers in making optimal decisions and clinicians in general clinical practice. More evidence about budget impact and affordability for patients is needed.

OBJECTIVE: The aim of this study was to estimate the effect of dietary consumption on cancer burden and formulate an effective solution. METHODS: Dietary consumption, number of cancer deaths, disability-adjusted life years, and corresponding age-standardized rates were extracted from the Global Burden of Disease Study 2019. The annual percentage change was used to quantify the temporal trends in cancer burden and dietary consumption. Age, sex, location, and sociodemographic index were stratified to further analyze the discrepancy in cancer burden attributable to dietary intake. RESULTS: Five cancers (breast, colon and rectal, tracheal, bronchus and lung, esophageal, and stomach) were documented to be associated with dietary consumption in the Global Burden of Disease database. The age-standardized death rate and age-standardized disability-adjusted life years rate in 2019 were 7.56 and 1168.77 per 100 000 population, respectively. For most cancers, the age-standardized death rate and age-standardized disability-adjusted life years rate displayed a decreasing tendency, with annual percentage change varying from -3.60 to -0.29 and from -3.64 to -0.03 from 1990 to 2019, respectively. The age-standardized death rate and age-standardized standardized disability-adjusted life years rate were higher in men than in women (9.68 vs 5.79 and 213.16 vs 129.18, respectively). In addition, the diet-related cancer burden in higher sociodemographic index regions exceeded that in lower sociodemographic index regions. CONCLUSION: Dietary consumption has a considerable influence on cancer burden, among which colon and rectal cancer burden account for the largest proportion. Increasing the intake of whole grains, milk, fiber, calcium, vegetables, and fruits and reducing the consumption of processed meat and sodium are instrumental in lowering the disease burden of cancer. The quantitative analysis of dietary consumption would provide a more detailed reference for diet-related decision makers and raise awareness of healthy dietary habits in diet management departments, food production enterprises, and the general public.

OBJECTIVES: This study provided estimates of cancer incidence rate and onset age by Socio-demographic Index (SDI) regions and gender from 2020 to 2040, aiming to clarify the long-term patterns of future cancer onset. METHOD: Based on the incidence data from the Global Burden of Diseases (GBD) 2019 study, we constructed the Bayesian age-period-cohort model to calculate the age-standardized incidence rates (ASIR) of cancers from 2020 to 2040. Using the average annual percentage change (AAPC) to quantify the trends of ASIR and the onset age. In addition, the incidences in 2019 were fixed to distinguish the age onset changes caused by demographic and incidence from 2020 to 2040. RESULTS: Globally, two-thirds of cancers have escalating trends of incidence rate, and the proportion of cancer weighted average onset age above 60 years old will grow from 62% to 76% between 2020 and 2040. In five SDI regions, the proportion of weighted average onset age above 60 years old will rise above 10% in the next 20 years and increase sequentially with the rise of the SDI level. Preclude sex-specific cancers, the onset age is younger in men than in women in 2040. Rule out the influence of changing demographics, half of cancer's morbidity has a youth-oriented tendency globally, which is concentrated in hormone-related and digestive tract cancer. CONCLUSION: From 2020 to 2040, the incidence and onset age changes demonstrate marked geographic and gender variations in the cancer spectrum. Cancer incidence and onset age are predicted to continuously increase worldwide in the future.

The normative regimens recommendations for treating metastatic uveal melanoma (mUM) are absent in the US. Recently, a phase III randomized clinical trial revealed that tebentafusp yielded a conspicuously longer overall survival than the control group. Based on the prominent efficacy, this study aimed to assess whether tebentafusp is cost-effective compared to the control group in patients with untreated mUM. A three-state partitioned survival model was developed to assess the costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratio (ICER) from the perspective of US payers. Scenario analyses and sensitivity analyses were conducted to explore the conclusion uncertainty. Compared with control group, tebentafusp therapy yielded an additional 0.47 QALYs (1.19 vs. 0.72 QALYs) and an incremental cost of $444â 280 ($633â 822 vs. $189â 542). The resultant ICER of $953â 230/QALY far outweighed the willingness-to-pay threshold of $200â 000/QALY. The ICER was always more than $750â 000/QALY in all the univariable and probabilistic sensitivity analyses. Scenario analyses indicated that reducing the unit price of tebentafusp to $33.768/µg was associated with a favorable result of tebentafusp being cost-effective. For treatment-naive patients with mUM, the cost of tebentafusp therapy was not worth the improvement in survival benefits at the current price compared to the investigator's choice of therapy. The cost-effectiveness of tebentafusp could be promoted using value-based pricing.

BACKGROUND: Recently, the DESTINY-Breast04 trial revealed that trastuzumab deruxtecan (T-DXd) significantly prolonged overall survival in patients with human epidermal growth factor receptor 2 (HER2)-low metastatic breast cancer (MBC). Considering the extraexpensive price of the new drug, a cost-effectiveness analysis of T-DXd is necessary to perform in the United States. In addition, because T-DXd has not been marketed in China, the pricing is a very important driver for the cost-effectiveness of T-DXd. The range of drug costs for which T-DXd could be considered cost-effective from a Chinese healthcare system perspective was explored. METHODS: We developed a Markov model to evaluate the cost-effectiveness of T-DXd versus physician's choice of chemotherapy (PCC). The simulation time horizon for this model was the life-time of patients. Transition probabilities were based on data from the DESTINY-Breast04 trial. Health utility data were derived from published studies. Outcome measures were costs (in 2022 US$), life-years (LYs), quality-adjusted LYs (QALYs), and the incremental cost-effectiveness ratio (ICER). One-way and probabilistic sensitivity analyses assessed the uncertainty of key model parameters and their joint impact on the base-case results. RESULTS: The model predicted that T-DXd provided an improvement of 0.84 LYs and 0.58 QALYs compared to PCC, with an ICER of $259,452.05 per QALY in the United States and $87,646.40 per QALY in China. The one-way sensitivity analysis demonstrated that the price of T-DXd had the greatest impact on ICERs. Probabilistic sensitivity analysis predicted that the probabilities of T-DXd being cost-effective compared to PCC were 7.2% and 0% at a willingness-to-pay of $150,000 per QALY in the United States and $36,475 per QALY (3 times the per capita gross domestic product) in China, respectively. Subgroup analyses showed that T-DXd was more effective for patients without visceral disease at baseline, followed by patients with Asian ethnic, patients without prior CDK 4/6 inhibitors therapy, and patients with HER2-1+ (IHC detection) status. CONCLUSION: T-DXd was unlikely to offer a reasonable value for the money spent compared to PCC for patients with HER2-low MBC in the United States. A value-based price for T-DXd was reduced by 51% in the United States and less than $1950 per cycle in China.

STUDY QUESTION: Is it economically worthwhile to use GnRH agonist (GnRHa) to prevent menopausal symptoms (MS) and protect fertility in premenopausal women with breast cancer (BC) during chemotherapy from the US perspective? SUMMARY ANSWER: It is cost-effective to administer GnRHa during chemotherapy in order to forefend MS in premenopausal patients with BC when the willingness-to-pay (WTP) threshold is $50â000.00 per quality-adjusted life-year (QALY), and to preserve fertility in young patients with BC who undergo oocyte cryopreservation (OC), or no OC, when the WTP thresholds per live birth are $71â333.33 and $61â920.00, respectively. WHAT IS KNOWN ALREADY: Chemotherapy often results in premature ovarian insufficiency (POI) in premenopausal survivors of BC, causing MS and infertility. Administering GnRHa during chemotherapy has been recommended for ovarian function preservation by international guidelines. STUDY DESIGN, SIZE, DURATION: Two decision-analytic models were developed, respectively, for preventing MS and protecting fertility over a 5-year period, which compared the cost-effectiveness of two strategies: adding GnRHa during chemotherapy (GnRHa plus Chemo) or chemotherapy alone (Chemo). PARTICIPANTS/MATERIALS, SETTING, METHODS: The participants were early premenopausal women with BC aged 18-49 years who were undergoing chemotherapy. Two decision tree models were constructed: one for MS prevention and one for fertility protection from the US perspective. All data were obtained from published literature and official websites. The models' primary outcomes included QALYs and incremental cost-effectiveness ratios (ICERs). The robustness of the models was tested by sensitivity analyses. MAIN RESULTS AND THE ROLE OF CHANCE: In the MS model, GnRHa plus Chemo resulted in an ICER of $17â900.85 per QALY compared with Chemo, which was greater than the WTP threshold of $50â000.00 per QALY; therefore, GnRHa plus Chemo was a cost-effective strategy for premenopausal women with BC in the USA. Probabilistic sensitivity analysis (PSA) results showed an 81.76% probability of cost-effectiveness in the strategy. In the fertility model, adding GnRHa for patients undergoing OC and those who were unable to undergo OC resulted in ICERs of $67â933.50 and $60â209.00 per live birth in the USA, respectively. PSA indicated that GnRHa plus Chemo was more likely to be cost-effective over Chemo when the WTP for an additional live birth exceed $71â333.33 in Context I (adding GnRHa to preserve fertility in young patients with BC after OC) and $61â920.00 in Context II (adding GnRHa to preserve fertility in young patients with BC who cannot accept OC). LIMITATIONS, REASONS FOR CAUTION: The indirect costs, such as disease-related mental impairment and non-medical costs (e.g. transportation cost) were not included. All data were derived from previously published literature and databases, which might yield some differences from the real world. In addition, the POI-induced MS with a lower prevalence and the specific strategy of chemotherapy were not considered in the MS model, and the 5-year time horizon for having a child might not be suitable for all patients in the fertility model. WIDER IMPLICATIONS OF THE FINDINGS: When considering the economic burden of cancer survivors, the results of this study provide an evidence-based reference for clinical decision-making, showing that it is worthwhile to employ GnRHa during chemotherapy to prevent MS and preserve fertility.

Combination therapy of zoledronic acid (ZOL) plus aromatase inhibitor (AI) was found to reduce bone metastasis risk and improve overall survival for treatment-naïve postmenopausal women (PMW) with hormone receptor-positive (HR+) early breast cancer (EBC), when compared with AI alone. The objective of this study was to evaluate the cost-effectiveness of adding ZOL to AI in treating PMW with HR+ EBC in China. A 5-state Markov model was constructed to evaluate the cost-effectiveness of adding ZOL to AI for PMW-EBC (HR+) over a lifetime horizon from the perspective of Chinese healthcare provider. Data used were obtained from previous reports and public data. The primary outcomes of this study were direct medical cost, life years (LYs), quality-adjusted LYs (QALYs), and incremental cost-effectiveness ratios (ICERs). One-way and probabilistic sensitivity analyses were performed to examine the robustness of the presented model. Over a lifetime horizon, adding ZOL to AI was projected to yield a gain of 1.286 LYs and 1.099 QALYs compared with AI monotherapy, which yielded ICER $11 140.75 per QALY with an incremental cost of $12 247.36. The one-way sensitivity analysis indicated that the cost of ZOL was the most influential factor in our study. The probability that adding ZOL to AI was cost-effective at a threshold of $30 425 per QALY in China was 91.1%. ZOL is likely to be cost-effective in reducing bone metastasis risk and improving overall survival for PMW-EBC (HR+) in China.

OBJECTIVE: Rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone, once every 3 weeks (R-CHOP21) is commonly used in non-Hodgkin's lymphoma (NHL), but accompanied by Pneumocystis carinii pneumonia (PCP) as a fatal treatment complication. This study aims to estimate the specific effectiveness and cost-effectiveness of PCP prophylaxis in NHL undergoing R-CHOP21. DESIGN: A two-part decision analytical model was developed. Prevention effects were determined by systemic review of PubMed, Embase, Cochrane Library and Web of Science from inception to December 2022. Studies reporting results of PCP prophylaxis were included. Enrolled studies were quality assessed with Newcastle-Ottawa Scale. Costs were derived from the Chinese official websites, and clinical outcomes and utilities were obtained from published literature. Uncertainty was evaluated through deterministic and probabilistic sensitivity analyses (DSA and PSA). Willingness-to-pay (WTP) threshold was set as US$31 315.23/quality-adjusted life year (QALY) (threefold the 2021 per capita Chinese gross domestic product). SETTING: Chinese healthcare system perspective. PARTICIPANTS: NHL receiving R-CHOP21. INTERVENTIONS: PCP prophylaxis versus no prophylaxis. MAIN OUTCOME MEASURES: Prevention effects were pooled as relative risk (RR) with 95% CI. QALYs and incremental cost-effectiveness ratio (ICER) were calculated. RESULTS: A total of four retrospective cohort studies with 1796 participants were included. PCP risk was inversely associated with prophylaxis in NHL receiving R-CHOP21 (RR 0.17; 95% CI 0.04 to 0.67; p=0.01). Compared with no prophylaxis, PCP prophylaxis would incur an additional cost of US$527.61, and 0.57 QALYs gained, which yielded an ICER of US$929.25/QALY. DSA indicated that model results were most sensitive to the risk of PCP and preventive effectiveness. In PSA, the probability that prophylaxis was cost-effective at the WTP threshold was 100%. CONCLUSION: Prophylaxis for PCP in NHL receiving R-CHOP21 is highly effective from retrospective studies, and routine chemoprophylaxis against PCP is overwhelmingly cost-effective from Chinese healthcare system perspective. Large sample size and prospective controlled studies are warranted.

Background: Life expectancy for patients with malignant tumors has been significantly improved since the presence of the programmed cell death protein-1/programmed cell death protein ligand-1 (PD-1/PD-L1) inhibitors in 2014, but they impose heavy financial burdens for patients, the healthcare system and the nations. The objective of this study was to determine the survival benefits, toxicities, and monetary of programmed cell death protein-1/programmed cell death protein ligand-1 inhibitors and quantify their values. Methods: Randomized controlled trials (RCTs) of PD-1/PD-L1 inhibitors for malignant tumors were identified and clinical benefits were quantified by American Society of Clinical Oncology Value Framework (ASCO-VF) and European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS). The drug price in Micromedex REDBOOK was used to estimate monthly incremental drug costs (IDCs) and the correlation between clinical benefits and incremental drug costs of experimental and control groups in each randomized controlled trial, and the agreement between two frameworks were calculated. Results: Up to December 2022, 52 randomized controlled trials were included in the quantitative synthesis. All the randomized controlled trials were evaluated by American society of clinical oncology value framework, and 26 (50%) met the American society of clinical oncology value framework "clinical meaningful value." 49 of 52 randomized controlled trials were graded by European society for medical oncology magnitude of clinical benefit scale, and 30 (61.2%) randomized controlled trials achieved European Society for Medical Oncology criteria of meaningful value. p-values of Spearman correlation analyses between monthly incremental drug costs and American society of clinical oncology value framework/European society for medical oncology magnitude of clinical benefit scale scores were 0.9695 and 0.3013, respectively. In addition, agreement between two framework thresholds was fair (κ = 0.417, p = 0.00354). Conclusion: This study suggests that there might be no correlation between the cost and clinical benefit of programmed cell death protein-1/programmed cell death protein ligand-1 inhibitors in malignancy, and the same results were observed in subgroups stratified by drug or indication. The results should be a wake-up call for oncologists, pharmaceutical enterprises and policymakers, and meanwhile advocate the refining of American Society of Clinical Oncology and European Society for Medical Oncology frameworks.
RESUMO
OBJECTIVES: The aim of this study was to evaluate the disease burden of prostate cancer (PC) and assess key influencing factors associated with the disease expenditures of PC in the United States. METHODS: The total deaths, incidence, prevalence, and disability-adjusted life-years of PC were obtained from the Global Burden of Disease Study 2019. The Medical Expenditure Panel Survey was used to estimate healthcare expenditures and productivity loss and to investigate patterns of payment and use of healthcare resources in the United States. A multivariable logistic regression model was conducted to identify key factors influencing expenditures. RESULTS: For patients aged 50 and older, the burden for all age groups showed a modest increase over the 6-year period. Annual medical expenditures were estimated to range from US$24.8 billion to US$39.2 billion from 2014 to 2019. The annual loss in productivity for patients was approximately US$1,200. The top 3 major components of medical costs were hospital inpatient stays, prescription medicines, and office-based visits. Medicare was the largest source of payments for survivors. In terms of drug consumption, genitourinary tract agents (57.0%) and antineoplastics (18.6%) were the main therapeutic drugs. High medical expenditures were positively associated with age (p=0.005), having private health insurance (p=0.016), more comorbidities, not currently smoking (p=0.001), and patient self-perception of fair/poor health status (p<0.001). CONCLUSIONS: From 2014 to 2019, the national real-world data of PC revealed that the disease burden in the United States continued to increase, which was partly related to patient characteristics.

BACKGROUND: Recently, a clinical trial (NCT02603432) showed that avelumab maintenance treatment, post first-line chemotherapy, can significantly prolong the overall survival of patients with advanced urothelial carcinoma (UC), however, the treatment was very expensive. This study aimed to determine the cost-effectiveness of avelumab maintenance therapy in advanced or metastatic UC from the US taxpayer perspective. METHODS: Based on the data of the JAVELIN Bladder 100 clinical trial (NCT02603432), a Markov multi-state model was constructed to investigate the costs and clinical outcomes of avelumab maintenance after platinum-based chemotherapy versus best supportive care (BSC) for advanced or metastatic UC. Parameters of the model came from the 2020 Average Sales Price Drug Pricing Files and published literature. The main outputs were costs, life years (LYs), quality-adjusted life years (QALYs), and incremental cost-effectiveness ratio (ICER). Robustness was tested by deterministic and probabilistic sensitivity analyses. The analysis was stratified to include both the overall population and a subset of programmed death-ligand 1 (PD-L1)-positive patients. RESULTS: Avelumab maintenance therapy was estimated to generate an additional 0.26 QALYs (1.46 vs. 1.20 QALYs) and costs $183,271 ($278,323 vs. $95,052) more compared to BSC alone in the overall population, yielding an ICER of $699,065/QALY. For the PD-L1-positive population, avelumab produced a 0.42 increase in QALYs (1.74 vs. 1.32 QALYs) and raised costs to $223,238 ($320,355 vs. $97,117), resulting in an ICER of $521,850/QALY for this population. Both ICERs were above the willingness-to-pay (WTP) threshold of $200,000/QALY. Sensitivity analyses manifested that the model was robust. CONCLUSION: From the perspective of the US taxpayer, avelumab maintenance therapy is considered cost-ineffective for patients with advanced or metastatic UC at a WTP threshold of $200,000/QALY in the overall population as well as in PD-L1-positive population.

OBJECTIVE: We evaluate cost-effectiveness of primary treatments for localised prostate cancer by uniquely combining prospectively collected real-world outcomes and costs from UCSF Cancer of Prostate Strategic Urologic Research Endeavor (CaPSURE™). METHODS: Markov models assessed cost-effectiveness of radical prostatectomy (RP), brachytherapy, electron beam radiation therapy (EBRT) and brachytherapy with EBRT by risk from US payers perspective over 8 years. Treatment costs included office visits, hospitalisation, procedures, medication and long-term care. Patients' surveyed HRQoL were mapped into utilities. Incremental cost-effectiveness ratios (ICERs) used cost per quality-adjusted life years (QALYs) and willingness-to-pay of $150,000/QALY. RESULTS: Cost-effectiveness analysis (CEA) showed for low-risk prostate cancer, EBRT dominated the lowest cost brachytherapy, but RPns and brachytherapy plus EBRT were cost-effective compared to brachytherapy with ICERs of $18,926 and $41,662 per QALY. In medium-risk patients, RP, EBRT and brachytherapy plus EBRT all were cost-effective compared with brachytherapy, with ICERs of $30,604, $22,588 and $21,627/QALY. In high-risk, brachytherapy dominated all treatments. Procedure cost and utility are driving ICER, but probabilistic sensitivity analysis showed the model was robust across variables. CONCLUSION: This first CEA combining prospective real-world evidence for HRQOL outcomes with costs shows cost-effectiveness of treatments vary by risk groups, providing new evidence for treatment decisions.

Thanks to its preparatory ease, close affinity, and low cost, the aptasensor can serve as a promising substitute for antibody-dependent biosensors. However, the available aptasensors are mostly subject to a single-mode readout and the interference of unbound aptamers in solution and non-target-induced transition events. Herein, we proposed a multimodal aptasensor for multimode detection of ochratoxin A (OTA) with cross-validation using the 3'-6-carboxyfluorescein (FAM)-enhanced exonuclease I (Exo I) tool and magnetic microbead carrier. Specifically, the 3'-FAM-labeled aptamer/biotinylated-cDNA hybrids were immobilized onto streptavidin-magnetic microbeads via streptavidin-biotin interaction. With the presence of OTA, an antiparallel G-quadruplex conformation was formed, protecting the 3'-FAM labels from Exo I digestion, and then anti-FAM-horseradish peroxidase (HRP) was bound via specific antigen-antibody affinity; for the aptamers without the protection of OTA, the distal ssDNA was hydrolyzed from 3' â 5', releasing 3'-FAM labels to the solution. Therefore, the OTA was detected by analyzing the "signal-off" fluorescence of the supernatant and two "signal-on" signals in electrochemistry and colorimetry through the detection of the coating magnetic microbeads in HRP's substrate. The results showed that the 3'-FAM labels increased the activity of Exo I, producing a low background due to a more thorough digestion of unbound aptamers. The proposed multimodal aptasensor successfully detected the OTA in actual samples. This work first provides a novel strategy for the development of aptasensors with Exo I and 3'-FAM labels, broadening the application of aptamer in the multimode detection of small molecules.

Objective: Recently, the significant improvement of atezolizumab and pembrolizumab over chemotherapy for treatment-naïve stage IV non-small cell lung cancer (NSCLC) has been demonstrated, but the cost-effectiveness of these regimens remains unknown. Methods: A Markov model was adapted from the US healthcare perspective to assess the cost-effectiveness of atezolizumab, pembrolizumab, and chemotherapy in treatment-naïve NSCLC. Pseudo-individual patient data were generated from digitized Kaplan-Meier curves. Direct medical costs and utility values were sourced from the database and literature. Quality-adjusted life-years (QALYs), total costs, and incremental cost-effectiveness ratios (ICERs) were computed. Sensitivity analyses and budgetary impact analyses were calculated. Results: In any and high programmed cell death 1-ligand 1 (PD-L1) expression populations, with chemotherapy, atezolizumab provided ICERs of $234,990 and $130,804 per QALY, while pembrolizumab yielded ICERs of $424,797 and $140,873 per QALY. The ICER of atezolizumab vs. pembrolizumab was $56,635 and $115,511.82 in any and high PD-L1 expression population, respectively. The critical drivers of ICERs included the cost of atezolizumab and pembrolizumab. The accumulated incremental budgetary impact of atezolizumab vs. chemotherapy increased to approximately $39.1 million in high PD-L1 expression patients over 5 years. Conclusions: In the high PD-L1 expression population, both atezolizumab and pembrolizumab were cost-effective for stage IV NSCLC compared to chemotherapy, which is contrary to that in any PD-L1 expression population. Atezolizumab shows a higher acceptability in both populations. Treating with immune checkpoint inhibitors (ICIs) has a substantial budgetary impact on the medical burden. The PD-L1 expression level has the potential to be a predictor for the economics of ICIs.
RESUMO
OBJECTIVES: The US Food and Drug Administration (FDA) approved nivolumab-ipilimumab and pembrolizumab-axitinib as first-line treatments for metastatic, clear-cell, renal cell carcinoma (mRCC) based on results from CheckMate 214 and KEYNOTE-426. Our objective was to compare the adjusted, lifetime cost-effectiveness between nivolumab-ipilimumab, pembrolizumab-axitinib, and sunitinib for patients with mRCC. MATERIALS AND METHODS: A 3-state Markov model was developed comparing nivolumab-ipilimumab and pembrolizumab-axitinib to each other and sunitinib, over a 20-year lifetime horizon from a US medical center perspective. The clinical outcomes of nivolumab-ipilimumab and pembrolizumab-axitinib were compared using matching-adjusted indirect comparison. Costs of drug treatment, adverse events, and utilities associated with different health states and adverse events were determined using national sources and published literature. Our outcome was incremental cost-effectiveness ratio (ICER) using quality-adjusted life years (QALY). One-way and probabilistic sensitivity analyses were conducted. RESULTS: Nivolumab-ipilimumab was the most cost-effective option in the base case analysis with an ICER of $34,190/QALY compared with sunitinib, while the pembrolizumab-axitinib ICER was dominated by nivolumab-ipilimumab and was not cost-effective (ICER=$12,630,828/QALY) compared with sunitinib. The mean total costs per patient for the nivolumab-ipilimumab and pembrolizumab-axitinib arms were $284,683 and $457,769, respectively, compared with sunitinib at $241,656. QALY was longer for nivolumab-ipilimumab (3.23 QALY) than for adjusted pembrolizumab-axitinib (1.99 QALY), which was longer than sunitinib's (1.98 QALY). These results were most sensitive to treatment cost in both groups, but plausible changes did not alter the conclusions. CONCLUSIONS: The base case scenario indicated that nivolumab-ipilimumab was the most cost-effective treatment option for mRCC compared with pembrolizumab-axitinib and sunitinib.

Background Few regimens for non-small cell lung cancer (NSCLC) with leptomeningeal metastases (LM) patients exist up to date, most with low efficacy. A retrospective analysis showed that osimertinib significantly improved the overall survival of LM patients by 11.5 months (17.0 vs. 5.5) as compared to no osimertinib treatment. Until now, no pharmacoeconomic evaluation of osimertinib has been performed to determine its feasibility for widespread use in LM patients. Aim This study analyzed the cost-effectiveness of osimertinib in LM of NSCLC from the perspective of the Chinese health care system. Methods Based on a retrospective analysis from the Samsung Medical Center, a Markov model was constructed to estimate the lifetime benefits and costs for LM patients who were treated with osimertinib. The main outcomes were cost, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratio (ICER). Sensitivity analyses were performed to verify the robustness of model. A budget impact analysis was conducted to estimate the annual incremental cost of osimertinib treatment. Results Compared with patients who were not treated with osimertinib, the survival time of patients treated with osimertinib was higher by 0.69 (1.24 vs. 0.55) QALYs. The incremental cost was $11,877 ($29,232 vs. $17,355) and the ICER was $17,214/QALY, which was below the willingness-to-pay threshold of $30,867/QALY. Osimertinib treatment will increase national cancer spending by $220 million in the first year and increase to $474 million in the fifth year. Conclusions Osimertinib treatment is deemed to be cost-effective for NSCLC with LM patients, however, its use would significantly increase annual cancer spending.

PURPOSE: To evaluate the cost-effectiveness of tucatinib in human epidermal growth factor receptor 2 (HER2)-positive breast cancer (BC) patients with brain metastases (BMs) and the subgroup of active BMs from the United States (US) payer perspective. MATERIALS AND METHODS: A 3-state Markov model was developed to compare the cost-effectiveness of 2 regimens in HER2-positive BC patients with BMs: (1) tucatinib, trastuzumab, and capecitabine (TTC); (2) placebo, trastuzumab, and capecitabine (PTC). And subgroup analysis of active BMs was also performed. Lifetime costs, quality-adjusted life years (QALYs), incremental cost-effectiveness ratio (ICER) and incremental net-health benefit (INHB) were estimated. The willingness-to-pay (WTP) threshold was $200,000/QALY. The robustness of the model was tested by sensitivity analyses. Additional scenario analysis was also performed. RESULTS: Compared with PTC, the ICER yielded by TTC was $418,007.01/QALY and the INHB was -1.08 QALYs in patients with BMs. In the subgroup of active BMs, the ICER and the INHB were $324,465.03/QALY and -0.71 QALY, respectively. The results were most sensitive to the cost of tucatinib. Probabilistic sensitivity analyses suggested that the cost-effective probability of TTC was low at the current WTP threshold in the patients with BMs and the subgroup of active BMs. CONCLUSION: Tucatinib is unlikely to be cost-effective in HER2-positive BC patients with BMs from the US payer perspective but shows better economics in patients with active BMs. Selecting a favorable population, reducing the price of tucatinib or offering appropriate drug assistance policies might be considerable options to optimize the cost-effectiveness of tucatinib.

Aim: To compare the cost-effectiveness of olaparib versus control treatment in metastatic castration-resistant prostate cancer patients with at least one gene mutation in BRCA1, BRCA2 or ATM from the US payer perspective. Methods: A Markov model was constructed to assess the quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios. Sensitivity analyses and scenario analyses were conducted to explore the impact of uncertainties. Results: The base-case result indicated that, for patients with specific gene mutations, olaparib gained 1.26 QALYs and USD$157,732 total cost. Compared with control treatment, the incremental cost-effectiveness ratio of olaparib was USD$248,248/QALY. The price of olaparib was the most influential parameter. Conclusion: Olaparib is not cost effective in comparison with control treatment in metastatic castration-resistant prostate cancer patients with specific gene mutations.
