Financial hardship experience in middle- and older-aged patients with advanced lung cancer.

PURPOSE: Advancements in medical treatments have resulted in increased medical costs for cancer patients. More than half of the patients with advanced lung cancer reported unmet financial needs. The purpose of this study is to examine the differences in the prevalence and correlates of financial hardship between middle- and older-aged patients with advanced lung cancer, and its impact on multiple health-related outcomes. METHODS: This study presents a cross-sectional analysis involving 226 patients with advanced lung cancer, who were enrolled in a randomized controlled trial conducted between 2018 and 2020. Data collection was performed through self-reported questionnaires and electronic medical records. Multivariable logistic and linear regression models were adopted for analysis. RESULTS: 58.0% reported experiencing financial hardships. Middle-aged participants who were single and had a lower education level were more likely to experience financial difficulties. However, males and higher performance status were associated with a lower likelihood of experiencing financial difficulties among older-aged participants. Financial hardship was significantly associated with anxiety (p < 0.001), depression (p < 0.001), sleep disturbances (p < 0.001), quality of life, global health status (p = 0.002), functional scale score (p < 0.001), symptom scale score (p < 0.001), and lung cancer-specific scale score (p < 0.001). CONCLUSIONS: More than half of the patients with advanced lung cancer experienced financial hardships caused by cancer or its treatment, with a higher prevalence reported in middle-aged patients. Different sociodemographic and clinical variables correlated with financial hardship in middle- and older-aged participants, respectively. More attention should be paid to middle-aged patients with advanced lung cancer, particularly during routine assessments.

International Cost-Effectiveness Analysis of Durvalumab in Stage III Non-Small Cell Lung Cancer.

Importance: Standard of care for unresectable locally advanced non-small cell lung cancer (NSCLC) involves definitive chemoradiotherapy followed by maintenance therapy with durvalumab. However, the cost of durvalumab has been cited as a barrier to its use in various health systems. Objective: To evaluate the cost-effectiveness of durvalumab vs placebo as maintenance therapy in patients with unresectable stage III NSCLC from 4 international payer perspectives (US, Brazil, Singapore, and Spain). Design, Setting, and Participants: In this economic evaluation, a Markov model was designed to compare the lifetime cost-effectiveness of maintenance durvalumab for unresectable stage III NSCLC with that of placebo, using 5-year outcomes data from the PACIFIC randomized placebo-controlled trial. Individual patient data were extracted from the PACIFIC, KEYNOTE-189, ADAURA, ALEX, and REVEL randomized clinical trials to develop a decision-analytic model to determine the cost-effectiveness of durvalumab compared with placebo maintenance therapy over a 10-year time horizon. Direct costs, adverse events, and patient characteristics were based on country-specific payer perspectives and demographic characteristics. The study was conducted from June 1, 2022, through December 27, 2023. Main Outcomes and Measures: Life-years, quality-adjusted life years (QALYs), lifetime costs, and incremental cost-effectiveness ratios (ICERs) were estimated at country-specific willingness-to-pay thresholds ([data reported in US$] US: $150 000 per QALY; Brazil: $22 251 per QALY; Singapore: $55 288 per QALY, and Spain: $107 069 per QALY). One-way and probabilistic sensitivity analyses were performed to account for parameters of uncertainty. A cost-threshold analysis was also performed. Results: The US base-case model found that treatment with durvalumab was associated with an increased cost of $114 394 and improved effectiveness of 0.50 QALYs compared with placebo, leading to an ICER of $228 788 per QALY. Incremental cost-effectiveness ratios, according to base-case models, were $141 146 for Brazil, $153 461 for Singapore, and $125 193 for Spain. Durvalumab price adjustments to the PACIFIC data improved cost-effectiveness in Singapore, with an ICER of $45 164. The model was most sensitive to the utility of durvalumab. Conclusions and Relevance: In this cost-effectiveness analysis of durvalumab as maintenance therapy for unresectable stage III NSCLC, the therapy was found to be cost-prohibitive from the perspective of various international payers according to country-specific willingness-to-pay thresholds per QALY. The findings of the study suggest that discounted durvalumab acquisition costs, as possible in Singapore, might improve cost-effectiveness globally.

Cost-effectiveness of additional serplulimab to chemotherapy in metastatic squamous non-small cell lung cancer patients.

Objective: To estimate the cost-effectiveness of adding serplulimab to chemotherapy for metastatic squamous non-small cell lung cancer (NSCLC) patients in a first-line setting from a Chinese perspective. Methods: A three-health state partitioned survival model was constructed to simulate disease development. The clinical data used in the model were derived from the ASTRUM-004 clinical trial. Only direct medical costs were included, and the utilities were derived from published literature. The quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratio (ICER) were employed to evaluate health outcomes. Additionally, a sensitivity analysis was performed to verify the robustness of the results. Results: Compared with chemotherapy alone, the addition of serplulimab resulted in an increase of 0.63 QALYs with an incremental cost of $5,372.73, leading to an ICER of $8,528.14 per QALY. This ICER was significantly lower than 3 times China's per capita GDP. The one-way sensitivity analysis suggested that the utility of PFS was the most sensitive factor on ICERs, followed by the price of serplulimab. Conclusion: The combination of serplulimab and chemotherapy has been shown to be a cost-effective initial treatment option for patients with metastatic squamous NSCLC with the commonly accepted willingness-to-pay threshold of 3 times the GDP per capita per QALY in China.

Evolution of Diagnoses, Survival, and Costs of Oncological Medical Treatment for Non-Small-Cell Lung Cancer over 20 Years in Osona, Catalonia.

Non-small-cell lung cancer (NSCLC) has experienced several diagnostic and therapeutic changes over the past two decades. However, there are few studies conducted with real-world data regarding the evolution of the cost of these new drugs and the corresponding changes in the survival of these patients. We collected data on patients diagnosed with NSCLC from the tumor registry of the University Hospital of Vic from 2002 to 2021. We analyzed the epidemiological and pathological characteristics of these patients, the diverse oncological treatments administered, and the survival outcomes extending at least 18 months post-diagnosis. We also collected data on pharmacological costs, aligning them with the treatments received by each patient to determine the cost associated with individualized treatments. Our study included 905 patients diagnosed with NSCLC. We observed a dynamic shift in histopathological subtypes from squamous carcinoma in the initial years to adenocarcinoma. Regarding the treatment approach, the use of chemotherapy declined over time, replaced by immunotherapy, while molecular therapy showed relative stability. An increase in survival at 18 months after diagnosis was observed in patients with advanced stages over the most recent years of this study, along with the advent of immunotherapy. Mean treatment costs per patient ranged from EUR 1413.16 to EUR 22,029.87 and reached a peak of EUR 48,283.80 in 2017 after the advent of immunotherapy. This retrospective study, based on real-world data, documents the evolution of pathological characteristics, survival rates, and medical treatment costs for NSCLC over the last two decades. After the introduction of immunotherapy, patients in advanced stages showed an improvement in survival at 18 months, coupled with an increase in treatment costs.

Critical Examination of Modeling Approaches Used in Economic Evaluations of First-Line Treatments for Locally Advanced or Metastatic Non-Small Cell Lung Cancer Harboring Epidermal Growth Factor Receptor Mutations: A Systematic Literature Review.

BACKGROUND: Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, with up to 32% of patients with NSCLC harboring an epidermal growth factor receptor (EGFR) mutation. NSCLC harboring an EGFR mutation has a dedicated treatment pathway, with EGFR tyrosine kinase inhibitors and platinum-based chemotherapy often being the therapy of choice. OBJECTIVE: The aim of this study was to systemically review and summarize economic models of first-line treatments used for locally advanced or metastatic NSCLC harboring EGFR mutations, as well as to identify areas for improvement for future models. METHODS: Literature searches were conducted via Ovid in PubMed, MEDLINE, MEDLINE In-Process, Embase, Evidence-Based Medicine Reviews: Health Technology Assessment, Evidence-Based Medicine Reviews: National Health Service Economic Evaluation Database, and EconLit. An initial search was conducted on 19 December 2022 and updated on 11 April 2023. Studies were selected according to predefined criteria using the Population, Intervention, Comparator, Outcome and Study design (PICOS) framework. RESULTS: Sixty-seven articles were included in the review, representing 59 unique studies. The majority of included models were cost-utility analyses (n = 52), with the remaining studies being cost-effectiveness analyses (n = 4) and a cost-minimization analysis (n = 1). Two studies incorporated both a cost-utility and cost-minimization analysis. Although the model structure across studies was consistently reported, justification for this choice was often lacking. CONCLUSIONS: Although the reporting of economic models in NSCLC harboring EGFR mutations is generally good, many of these studies lacked sufficient reporting of justification for structural choices, performing extensive sensitivity analyses and validation in economic evaluations. In resolving such gaps, the validity of future models can be increased to guide healthcare decision making in rare indications.

Impact of Lung Cancer on Health-Related Quality of Life, Financial Toxicity, and Household Economics in Patients From the Public and the Private Healthcare Sector in Argentina.

OBJECTIVES: Non-small cell lung cancer (NSCLC) is Argentina's first cause of cancer death. Most patients have an advanced stage at diagnosis, with poor expected survival. This study aimed to characterize the health-related quality of life (HRQOL) and economic impact of patients treated in the private healthcare sector and compare it with that of the public sector. METHODS: We undertook an observational cross-sectional study that extended a previous study to a referral private center in Argentina. Outcomes included the EuroQol EQ-5D-3L (to assess HRQOL), Comprehensive Score for Financial Toxicity (financial toxicity instrument), Work Productivity and Activity Impairment - General Health (to assess productivity loss), and out-of-pocket expenses in adults diagnosed of NSCLC. RESULTS: We included 30 consecutive patients from a private healthcare center (July 2021 to March 2022), totaling 131 patients (n = 101 from previous public study). The whole sample had low quality of life and relevant economic impact. Patients in the private healthcare sector showed lower disease severity and higher educational level and household income. In addition, private healthcare system patients showed higher utility (0.77 vs 0.73; P < .05) and lower impairment of daily activities (41% vs 59%; P = .01). Private health system patients also showed lower financial toxicity as measured by the Comprehensive Score for Financial Toxicity score (23.9 vs 20.14; P < .05) but showed no differences when financial toxicity was assessed as a dichotomic variable. CONCLUSIONS: Although patients with NSCLC treated in a private healthcare center in Argentina showed a relevant HRQOL and economic impact, this impact was smaller than the one observed in publicly funded hospitals.

A look ahead to promote the early detection of lung cancer: technical and cost implications of a confirmed diagnosis before surgery / Una mirada al futuro para promover la detección temprana del Cáncer de Pulmón: implicaciones técnicas y económicas de tener un diagnóstico confirmado antes de la cirugía

Objective: To compare the costs and length of hospital stay among patients with a confirmed diagnosis of lung cancer (LC) prior to surgery versus those without confirmation. Methods: This retrospective, single-center study was conducted in patients who underwent a surgical procedure for LC, with or without a pathologically confirmed LC diagnosis prior to surgery, between March 2017 and December 2019. The main outcomes were costs and length of hospital stay (LOS). Results: Among the 269 patients who underwent surgery for lung cancer between March 2017 and December 2019, 203 (75.5%) patients underwent surgery due to a histopathological diagnosis, and 66 (24.5%) because of a Multidisciplinary Cancer Committee indication. The unadjusted mean cost was significantly lower in Group II (patients with surgery based on Multidisciplinary Cancer Committee criteria) (Є2,581.80 ± Є1,002.50) than in Group I (patients with histopathological diagnosis) (Є4,244.60 ± Є2,008.80), P < 0.0001. Once adjusted for covariables, there was a mean difference of −Є1,437.20 in the costs of Group II, P < 0.0001. Unadjusted mean hospital stay was significantly longer in Group I (5.6 days) than in Group II (3.5 days). Conclusions: The results suggest that indicating surgical resection of lung cancer based on Multidisciplinary Cancer Committee criteria, rather than performing CT-guided percutaneous lung biopsy, may result in a significant decrease in cost and length of hospital stay.

Objetivo: Comparar los costes y la duración de la estancia hospitalaria entre los pacientes con un diagnóstico confirmado de cáncer de pulmón (CP) antes de la cirugía frente a los que no lo tienen. Métodos: Estudio retrospectivo y unicéntrico realizado en pacientes que se sometieron a un procedimiento quirúrgico de CP, con o sin diagnóstico de CP confirmado patológicamente antes de la cirugía, entre marzo de 2017 y diciembre de 2019. Los principales resultados fueron los costes y la duración de la estancia hospitalaria (LOHS). Resultados: Entre los 269 pacientes sometidos a cirugía por cáncer de pulmón entre marzo de 2017 y diciembre de 2019, 203 (75,5%) pacientes se operan por diagnóstico histopatológico y 66 (24,5%) por indicación del Comité Oncológico Multidisciplinar. El coste medio no ajustado fue significativamente menor en el Grupo II (pacientes con intervención quirúrgica basada en criterios del Comité Multidisciplinar del Cáncer) (2.581,8 ± 1.002,5Є) que en el Grupo I (pacientes con diagnóstico histopatológico) (4.244,6Є ± 2.008,8), p < 0,0001. Una vez ajustados por covariables, hubo una diferencia media de −1.437,2Є en los costes del Grupo II, p < 0,0001. La estancia hospitalaria media no ajustada fue significativamente mayor en el Grupo I (5,6 días) que en el Grupo II (3,5 días). Conclusiones: Los resultados sugieren que indicar la resección quirúrgica del cáncer de pulmón basándose en los criterios del Comité Multidisciplinar del Cáncer, en lugar de realizar una biopsia pulmonar percutánea guiada por TAC, puede suponer una disminución significativa del coste y de la duración de la estancia hospitalaria.

Economic evaluation of toripalimab combined with chemotherapy in the treatment of non-small cell lung cancer.

Background and objective: The CHOICE-01 trial showed that toripalimab plus chemotherapy achieved satisfactory outcomes compared with chemotherapy in patients with advanced non-small cell lung cancer (NSCLC) who were negative for driver genes, but the economics of this regimen is unclear. Therefore, this study aimed to evaluate the cost-effectiveness of toripalimab in combination with chemotherapy in advanced NSCLC with negative driver genes from the perspective of the Chinese healthcare system. Materials and methods: A three-state partitioned survival model was developed to simulate the costs and outcomes associated with adding toripalimab to first-line chemotherapy. The clinical data in the model came from the CHOICE-01 trial, only direct medical costs were included, and utility values were referred to the literature. Four models were applied to explore the differences in the results of fitting and extrapolating K-M curves from different models, and cost-effectiveness subgroup analysis was performed. The incremental cost-effectiveness ratio (ICER) was used as the main outcome measure. Sensitivity analysis was performed to assess the impact of parameter uncertainty on the model. Results: The baseline analysis showed that toripalimab coupled with chemotherapy cost $21,052 more than chemotherapy ($43,197 vs. $22,145) and also gained 0.71 QALYs more (1.75 QALYs vs. 1.03 QALYs), with an ICER of $29,478/QALYs. At the current willingness-to-pay threshold ($35,108/QALY), the extra cost was well worth it. The results of fitting and extrapolating the survival curves using other models were consistent with the results of the standard parametric model. Subgroup analysis demonstrated that the addition of toripalimab to chemotherapy was economical. Sensitivity analysis showed that the utility values of PD and PFS stages had the greatest impact on the model. Conclusion: From the viewpoint of the Chinese healthcare system, toripalimab combined with chemotherapy in the treatment of advanced NSCLC with negative driver genes was likely to be cost-effective compared with chemotherapy.

Breast, Cervical, and Lung Cancer: A comparison of Real Healthcare Costs and INA-CBGs Rates in the Era of National Health Insurance

Background: In Indonesia, the cost of cancer treatment has been determined by the Indonesian Case Base Groups (INA-CBGs) based on a code called the INA-CBG’s rates. However, a fair claim should be based on the severity of the disease and the class of treatment in the hospital, not on the rates of code. In fact, the real cost of therapy for cancer is influenced by several factors including stage, comorbidity, and severity (INA-CBGs coding, type of hospital, hospital class, treatment grade, side effects, and length of stay), so in many cases, there are reported differences between the real costs and the INA-CBGs rates charged to patients. Objective: This study aims to investigate the difference between real treatment costs and INA-CBG’s rates for cases of lung cancer, cervical cancer, and breast cancer at a cancer center hospital in Indonesia. Methods: This work uses an observational study, and the data were taken retrospectively from hospital financial data and patient medical records. The data were then analyzed using a one-sample t-test to determine the difference between real costs and INA-CBGs costs. Results: The results showed that there was no significant difference between real costs and INA-CBG’s cost on stage II lung cancer treatment in grade 2 with a sig. value of 0.683; code C-4-13-II in grade 3 with a sig. value of 0.151; and code C-4-13-III in grade 3 with a sig. value of 0.650; where the significance level (t alpha) is more than 0.05. Furthermore, the treatment costs for cervical cancer with codes C-4- 13-I and C-4-13-II in grade 1 had sig. values of 0.155 and 0.720 respectively. Lastly, the treatment cost for breast cancer patients with codes C-4-12-II in grade 3 had a sig. value of 0.145 and code C-4-13-II in grade 3 showed a sig. value of 0.091. (AU)

A systematic review of economic evaluations of tyrosine kinase inhibitors for non-small cell lung cancer (NSCLC).

INTRODUCTION: Although tyrosine kinase inhibitors (TKIs) have improved the efficacy of treatment for non-small cell lung cancer (NSCLC), the accessibility of TKIs is limited due to high costs. Despite the critical role of the cost-effectiveness of TKIs on decision-making, no systematic reviews have compared the cost-effectiveness of comparable TKIs. Therefore, we systemically reviewed the economic evaluation studies on various TKIs for NSCLC. AREAS COVERED: We searched PubMed and the Cochran Library to identify the published economic evaluation studies of TKIs in NSCLC patients that were published by January 2022. All of the included studies (n = 38) evaluated the cost-effectiveness of epidermal growth factor receptor (EGFR)-TKIs (n = 29) or anaplastic lymphocyte kinase (ALK)-TKIs (n = 9). The cost-effectiveness results were reported as the incremental cost-effectiveness ratio per quality-adjusted life-year, except for three studies. EXPERT OPINION: We found that the economic evaluation studies of the first and second generation of EGFR-TKIs and ALK-TKIs varied by the country and study settings, such as comparator and input parameters. In 12 studies, osimertinib (EGFR-TKI) was not cost-effective compared to other first/second EGFR-TKIs, regardless of the study settings. More evidence can be provided about cost-effectiveness of the third-generation TKIs in future research.

Trends in treatment patterns and survival outcomes in advanced non-small cell lung cancer: a Canadian population-based real-world analysis.

BACKGROUND: As part of the multi-country I-O Optimise research initiative, this population-based study evaluated real-world treatment patterns and overall survival (OS) in patients treated for advanced non-small cell lung cancer (NSCLC) before and after public reimbursement of immuno-oncology (I-O) therapies in Alberta province, Canada. METHODS: This study used data from the Oncology Outcomes (O2) database, which holds information for ~ 4.5 million residents of Alberta. Eligible patients were adults newly diagnosed with NSCLC between January 2010 and December 2017 and receiving first-line therapy for advanced NSCLC (stage IIIB or IV) either in January 2010-March 2016 (pre-I-O period) or April 2016-June 2019 (post-I-O period). Time periods were based on the first public reimbursement of I-O therapy in Alberta (April 2017), with a built-in 1-year lag time before this date to allow progression to second-line therapy, for which the I-O therapy was indicated. Kaplan-Meier methods were used to estimate OS. RESULTS: Of 2244 analyzed patients, 1501 (66.9%) and 743 (33.1%) received first-line treatment in the pre-I-O and post-I-O periods, respectively. Between the pre-I-O and post-I-O periods, proportions of patients receiving chemotherapy decreased, with parallel increases in proportions receiving I-O therapies in both the first-line (from < 0.5% to 17%) and second-line (from 8% to 47%) settings. Increased use of I-O therapies in the post-I-O period was observed in subgroups with non-squamous (first line, 15%; second line, 39%) and squamous (first line, 25%; second line, 65%) histology. First-line use of tyrosine kinase inhibitors also increased among patients with non-squamous histology (from 26% to 30%). In parallel with these evolving treatment patterns, median OS increased from 10.2 to 12.1 months for all patients (P < 0.001), from 11.8 to 13.7 months for patients with non-squamous histology (P = 0.022) and from 7.8 to 9.4 months for patients with squamous histology (P = 0.215). CONCLUSIONS: Following public reimbursement, there was a rapid and profound adoption of I-O therapies for advanced NSCLC in Alberta, Canada. In addition, OS outcomes were significantly improved for patients treated in the post-I-O versus pre-I-O periods. These data lend support to the emerging body of evidence for the potential real-world benefits of I-O therapies for treatment of patients with advanced NSCLC.

Clinical and economic impact of 'ROS1-testing' strategy compared to a 'no-ROS1-testing' strategy in advanced NSCLC in Spain.

BACKGROUND: Detection of the ROS1 rearrangement is mandatory in patients with advanced or metastatic non-small cell lung cancer (NSCLC) to allow targeted therapy with specific inhibitors. However, in Spanish clinical practice ROS1 determination is not yet fully widespread. The aim of this study is to determine the clinical and economic impact of sequentially testing ROS1 in addition to EGFR and ALK in Spain. METHODS: A joint model (decision-tree and Markov model) was developed to determine the cost-effectiveness of testing ROS1 strategy versus a no-ROS1 testing strategy in Spain. Distribution of ROS1 techniques, rates of testing, positivity, and invalidity of biomarkers included in the analysis (EGFR, ALK, ROS1 and PD-L1) were based on expert opinion and Lungpath real-world database. Treatment allocation depending on the molecular testing results was defined by expert opinion. For each treatment, a 3-states Markov model was developed, where progression-free survival (PFS) and overall survival (OS) curves were parameterized using exponential extrapolations to model transition of patients among health states. Only medical direct costs were included (€ 2021). A lifetime horizon was considered and a discount rate of 3% was applied for both costs and effects. Both deterministic and probabilistic sensitivity analyses were performed to address uncertainty. RESULTS: A target population of 8755 patients with advanced NSCLC (non-squamous or never smokers squamous) entered the model. Over a lifetime horizon, the ROS1 testing scenario produced additional 157.5 life years and 121.3 quality-adjusted life years (QALYs) compared with no-ROS1 testing scenario. Total direct costs were increased up to € 2,244,737 for ROS1 testing scenario. The incremental cost-utility ratio (ICUR) was 18,514 €/QALY. Robustness of the base-case results were confirmed by the sensitivity analysis. CONCLUSIONS: Our study shows that ROS1 testing in addition to EGFR and ALK is a cost-effective strategy compared to no-ROS1 testing, and it generates more than 120 QALYs in Spain over a lifetime horizon. Despite the low prevalence of ROS1 rearrangements in NSCLC patients, the clinical and economic consequences of ROS1 testing should encourage centers to test all advanced or metastatic NSCLC (non-squamous and never-smoker squamous) patients.

Patterns of Medical Care Cost by Service Type for Patients With Recurrent and De Novo Advanced Cancer.

OBJECTIVES: There is limited knowledge about the cost patterns of patients who receive a diagnosis of de novo and recurrent advanced cancers in the United States. METHODS: Data on patients who received a diagnosis of de novo stage IV or recurrent breast, colorectal, or lung cancer between 2000 and 2012 from 3 integrated health systems were used to estimate average annual costs for total, ambulatory, inpatient, medication, and other services during (1) 12 months preceding de novo or recurrent diagnosis (preindex) and (2) diagnosis month through 11 months after (postindex), from the payer perspective. Generalized linear regression models estimated costs adjusting for patient and clinical factors. RESULTS: Patients who developed a recurrence <1 year after their initial cancer diagnosis had significantly higher total costs in the preindex period than those with recurrence ≥1 year after initial diagnosis and those with de novo stage IV disease across all cancers (all P < .05). Patients with de novo stage IV breast and colorectal cancer had significantly higher total costs in the postindex period than patients with cancer recurrent in <1 year and ≥1 year (all P < .05), respectively. Patients in de novo stage IV and those with recurrence in ≥1 year experienced significantly higher postindex costs than the preindex period (all P < .001). CONCLUSIONS: Our findings reveal distinct cost patterns between patients with de novo stage IV, recurrent <1-year, and recurrent ≥1-year cancer, suggesting unique care trajectories that may influence resource use and planning. Future cost studies among patients with advanced cancer should account for de novo versus recurrent diagnoses and timing of recurrence to obtain estimates that accurately reflect these care pattern complexities.

Cost-effectiveness and health impact of lung cancer screening with low-dose computed tomography for never smokers in Japan and the United States: a modelling study.

BACKGROUND: Never smokers in Asia have a higher incidence of lung cancer than in Europe and North America. We aimed to assess the cost-effectiveness of lung cancer screening with low-dose computed tomography (LDCT) for never smokers in Japan and the United States. METHODS: We developed a state-transition model for three strategies: LDCT, chest X-ray (CXR), and no screening, using a healthcare payer perspective over a lifetime horizon. Sensitivity analyses were also performed. Main outcomes were costs, quality-adjusted life-years (QALYs), life expectancy life-years (LYs), incremental cost-effectiveness ratios (ICERs), and deaths from lung cancer. The willingness-to-pay level was US$100,000 per QALY gained. RESULTS: LDCT yielded the greatest benefits with the lowest cost in Japan, but the ICERs of LDCT compared with CXR were US$3,001,304 per QALY gained for American men and US$2,097,969 per QALY gained for American women. Cost-effectiveness was sensitive to the incidence of lung cancer. Probabilistic sensitivity analyses demonstrated that LDCT was cost-effective 99.3-99.7% for Japanese, no screening was cost-effective 77.7% for American men, and CXR was cost-effective 93.2% for American women. Compared with CXR, LDCT has the cumulative lifetime potential for 60-year-old Japanese to save US$117 billion, increase 2,339,349 QALYs and 3,020,102 LYs, and reduce 224,749 deaths, and the potential for 60-year-old Americans to cost US$120 billion, increase 48,651 QALYs and 67,988 LYs, and reduce 2,309 deaths. CONCLUSIONS: This modelling study suggests that LDCT screening for never smokers has the greatest benefits and cost savings in Japan, but is not cost-effective in the United States. Assessing the risk of lung cancer in never smokers is important for introducing population-based LDCT screening.

Trends in Prices of Drugs Used to Treat Metastatic Non-Small Cell Lung Cancer in the US From 2015 to 2020.

Importance: Oncology drug prices are a determinant of health disparities in the US and worldwide. Several new therapeutic agents for non-small cell lung cancer (NSCLC) have become available on the US market over the past decade. Although increased competition typically produces lower prices, competition among brand-name oncology drugs has not resulted in lower prices. Objective: To assess price changes in class-specific brand-name medications used to treat metastatic NSCLC in the US from 2015 to 2020. Design, Setting, and Participants: This cross-sectional study, conducted from August 13, 2015, to August 13, 2020, used data from the Micromedex Red Book and Medi-Span Price Rx databases. The study sample was limited to 17 brand-name medications used to treat metastatic NSCLC that were available for purchase before January 1, 2019. Main Outcomes and Measures: The main outcomes were trends over time in average wholesale prices and wholesale acquisition cost unit prices and the correlation in price among the multiple brand-name medications within each therapeutic class (immune checkpoint inhibitors, epidermal growth factor receptor inhibitors, anaplastic lymphoma kinase inhibitors, ROS1 inhibitors, BRAF inhibitors, and MEK inhibitors), measured using the Pearson correlation coefficient. The compounded annual growth rates of different medication costs were compared with the annual inflation rate and the consumer price index for prescription drugs. Results: For all drug classes, the Pearson correlation coefficient approached 1.0, indicating an increase in drug list prices despite within-class drug competition. The median Pearson correlation coefficient values were 0.964 (range, 0.951-0.994) for immune checkpoint inhibitors, 0.898 (range, 0.665-0.950) for epidermal growth factor receptor inhibitors, 0.999 (range, 0.982-0.999) for anaplastic lymphoma kinase inhibitors, and 0.999 for BRAF and MEK inhibitors. The median compounded annual growth rates for most drug costs were higher than the annual inflation rate and consumer price index for prescription drugs: 1.81% (range, 1.29%-2.13%) for immune checkpoint inhibitors, 2.56% (range, 2.38%-5.26%) for epidermal growth factor receptor inhibitors, 2.46% (range, 1.75%-4.66%) for anaplastic lymphoma kinase and ROS1 inhibitors, and 3.06% (range, 0%-3.06%) for BRAF and MEK inhibitors. Conclusions and Relevance: In this cross-sectional study, prices of brand-name medications for treatment of NSCLC increased in the US from 2015 to 2020 without evidence of price competition, raising concern about the affordability of promising oncology drugs. These findings suggest that drug pricing reform is needed.

Health care resource utilization and costs associated with advanced or metastatic nonsmall cell lung cancer in the United States.

BACKGROUND: The treatment landscape for advanced nonsmall cell lung cancer (NSCLC) has evolved from 2015 onward, since the introduction of immune checkpoint inhibitors (ICIs). Considering this shift, there have been limited prior analyses that assess the economic burden of NSCLC within the current treatment landscape. OBJECTIVE: To present an analysis of health care resource utilization (HCRU) and costs associated with the treatment of patients with advanced or metastatic NSCLC in the United States between 2010 and 2019. METHODS: Patients with locally advanced or metastatic NSCLC who initiated first-line (1L) systemic treatment between January 1, 2010, and June 30, 2019, were included from the HealthCore Integrated Research Database using a previously developed claims-based predictive model algorithm. Mean total HCRU and costs and mean per-person-per-year (PPPY) HCRU and costs were estimated for 2 follow-up periods: the time during the entire follow-up period and the time during the 1L treatment period. Distribution of treatment classes (defined as chemotherapy, ICIs, targeted therapies, and others) were also analyzed by index year. RESULTS: 27,257 patients met the eligibility criteria and were included in the analysis. The mean duration of follow-up for all patients was 16.6 months (median 10.6 months), and the median time to discontinuation of 1L treatment was 2.8 months. The number of outpatient visits accounted for the majority of HCRU across the entire study follow-up (mean 97.7 in total and 147.1 PPPY) and for the 1L treatment period (mean 46.3 in total and 167.5 PPPY). The total mean cost across the entire study follow-up was $158,908 ($250,942 PPPY). For the 1L treatment period, the total mean cost was $72,760 ($271,590 PPPY). Total mean outpatient costs for systemic anticancer treatment were $61,797 for the entire study follow-up ($85,609 PPPY) and $27,138 during the 1L treatment period ($92,412 PPPY). Total costs increased over the study duration, which were mainly due to increasing outpatient costs for systemic therapy. In both follow-up periods, inpatient costs, other outpatient costs (nonsystemic therapy-related costs), and pharmacy costs remained relatively stable but still accounted for more than 60% of the total costs. Analysis of treatment classes over time showed that chemotherapy was the most frequently used treatment, regardless of line of therapy. A trend was observed for increased ICI use from 2015 onward. CONCLUSIONS: Despite the improvement in treatment options, a high economic burden associated with the treatment of NSCLC still exists. The total costs have been increasing, mainly driven by outpatient costs for systemic therapy, which might reflect the greater use of ICIs for advanced NSCLC. Costs for inpatient services, other outpatient services, and pharmacy services remained stable but still accounted for the majority of the economic burden. Further studies are required to assess the impact of innovative treatments on the disease management costs of advanced NSCLC.

Cost-effectiveness of carbon-ion radiotherapy versus stereotactic body radiotherapy for non-small-cell lung cancer.

Carbon-ion radiotherapy (CIRT) for clinical stage I non-small-cell lung cancer (NSCLC) is used as an advanced medical treatment regimen in Japan. Carbon-ion radiotherapy reportedly aids in achieving excellent treatment outcomes, despite its high medical cost. We aimed to compare CIRT with stereotactic body radiotherapy (SBRT) in terms of cost-effectiveness for treating clinical stage I NSCLC. Data of patients with clinical stage I NSCLC treated with CIRT or SBRT at Gunma University between 2010 and 2015 were analyzed. The CIRT and SBRT groups included 62 and 27 patients, respectively. After propensity-score matching, both groups comprised 15 patients. Life year (LY) was used as an indicator of outcome. The CIRT technical fee was 3 140 000 JPY. There was no technical fee for the second CIRT carried out on the same organ within 2 years. The incremental cost-effectiveness ratio (ICER) was calculated by dividing the incremental cost by the incremental LY for 5 years after treatment. Sensitivity analysis was applied to evaluate the impact of LY or costs of each group on ICER. The ICERs were 7 491 017 JPY/LY and 3 708 330 JPY/LY for all patients and matched patients, respectively. Hospitalization and examination costs were significantly higher in the CIRT group, and the impact of the CIRT technical costs was smaller than other costs and LY. Carbon-ion radiotherapy is a cost-effective treatment approach. However, our findings suggest that reducing excessive costs by considering the validity and necessity of examinations and hospitalizations would make CIRT a more cost-effective approach.

Catastrophic health expenditure and its determinants in households with lung cancer patients in China: a retrospective cohort study.

BACKGROUND: Numerous studies have examined catastrophic health expenditures (CHE) worldwide, mostly focusing on general or common chronic populations, rather than particularly vulnerable groups. This study assessed the medical expenditure and compensation of lung cancer, and explored the extent and influencing factors of CHE among households with lung cancer patients in China. METHODS: During 2018-2019, a hospital-based multicenter retrospective survey was conducted in seven provinces/municipalities across China as a part of the Cancer Screening Program of Urban China. CHE was measured according to the proportion of out-of-pocket (OOP) health payments of households on non-food expenditures. Chi-square tests and logistic regression analysis was adjusted to determine the factors that significantly influenced the likelihood of a household with lung cancer patient to incur in CHE. RESULTS: In total, 470 households with lung cancer patients were included in the analysis. Health insurance was shown to protect some households from the impact of CHE. Nonetheless, CHE incidence (78.1%) and intensity (14.02% for average distance and 22.56% for relative distance) were still relatively high among households with lung cancer patients. The incidence was lower in households covered by the Urban Employee Basic Medical Insurance (UEMBI) insurance, with higher income level and shorter disease course. CONCLUSION: More attention is needed for CHE incidence among vulnerable populations in China. Households with lung cancer patients were shown to be more likely to develop CHE. Therefore, policy makers should focus on improving the financial protection and reducing the economic burden of this disease.
