The cost of lung cancer in Alberta

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.

Cost of Lung Cancer: A Systematic Review

OBJECTIVES

We performed a systematic review of studies estimating the cost of illness of lung cancer to compare costs between studies and examine cost drivers, emphasizing generalizability and methodological choices.

METHODS

A systematic search on studies published in English on cost of illness of lung cancer was performed in MEDLINE (PubMed), Embase, Web of Science, and Scopus. Databases were searched in January 2017, and records were screened based on eligibility criteria. The systematic search was updated on May 7, 2020. The quality of included studies was appraised using a modified Drummond checklist.

RESULTS

Of the 4891 records screened, 19 records were included. Most of the studies were cross-sectional and retrospective and used a prevalence-based approach and a bottom-up approach. Direct medical costs ranged from 4484.13 US dollars purchasing power parity to 45 364.48 US dollars purchasing power parity. Total medical costs as a percentage of total gross domestic product (GDP) ranged from 0.00248 to 0.1326 (median 0.0217), and total medical costs as a percentage of total health expenditure ranged from 0.038 to 0.836 (median 0.209).

CONCLUSIONS

There was considerable methodological heterogeneity that made it difficult to compare results between studies. The costs of lung cancer are substantial and impose a substantial economic burden on patients, healthcare systems, and societies. By comparing cancer costs with total health expenditures and GDP per capita, it can be concluded that lung cancer imposes a considerable economic burden on patients and healthcare systems in countries with lower GDP per capita and higher incidence rate.

Probabilistic health risk assessment of occupational exposure to crystalline silica in an iron foundry in Urmia, Iran

This study aimed to quantify the exposure of foundry workers to crystalline silica and associated cancer and non-cancer health risks using a probabilistic approach. Breathing zone air samples were collected according to the NIOSH 7602 method and analyzed using Fourier transform infrared spectroscopy. The health risks posed by crystalline silica were then assessed using the EPA-developed inhalation risk assessment model and Monte Carlo simulation. The sensitivity analysis was also conducted to determine the contribution of input parameters to the health risks. The mean concentration of crystalline silica in six foundry stations ranged from 0.029 to 0.064 mg m-3, exceeding the occupational exposure limits. The average values of cancer risks were greater than the USEPA level, i.e., 1E - 6 in all workstations of the foundry. Workers in sand preparation and molding stations suffered the greatest cancer risks, with the mean value of 2.35E - 5 and 2.10E - 5, respectively. Non-cancer hazard quotient exceeded 1 in all foundry stations ranging from 1.56 (in melting and pouring) to 3.37 (in sand preparation). The 95% upper-bound values of the health risks decreased by 77.52% and 56.77%, assuming the use of engineering controls and wearing respirators by workers, respectively. Sensitivity analyses indicate that concentration was the most sensitive factor contributing to the carcinogenic (46.13%) and non-carcinogenic (67.08%) risks. These findings can aid managers in gaining a better understanding of the silica risks faced by foundry workers and the role of engineering controls and respirators in protecting workers' health.

The medicalization of cancer as socially constructed and culturally negotiated

Sociological considerations of medicalization frequently employ a limited use of the term that focuses on the transformation of social phenomena into issues subject to medical control. Informed by a salutogenic perspective, this essay argues that it is possible to understand cancer as having been medicalized. I show that far from exclusively a biophysical issue, the medicalization of cancer is a socially constructed and culturally negotiated process, with a fairly recent historical origin. While changing social relations of healing have led our medico-centric culture to a near single-minded understanding of cancer as a cellular pathology rooted in biology, Antonovsky's salutogenic perspective instructs that it is possible to understand and control cancer in non-medicalized ways. Indoor radon gas remediation is presented as an illustration of what form salutary cancer control and disease prevention may take.

Economic burden of lung cancer in Turkey: a cost of illness study from payer perspective

BACKGROUND

This study was designed to estimate economic burden of lung cancer in Turkey from payer perspective based on expert panel opinion on practice patterns in clinical practice.

METHODS

In this cost of illness study, direct medical cost was calculated based on cost items related to outpatient visits, laboratory and radiological tests, hospitalizations/interventions, drug treatment, adverse events and metastasis. Indirect cost was calculated based on lost productivity due to early retirement, morbidity and premature death resulting from the illness, the value of lost productivity due to time spent by family caregivers and cost of formal caregivers.

RESULTS

Cost analysis revealed the total per patient annual direct medical cost for small cell lung cancer to be €8772), for non-small-cell lung cancer to be €10,167. Total annual direct medical cost was €497.9 million, total annual indirect medical cost was €1.1 billion and total economic burden of lung cancer was €1.6 billion. Hospitalization/interventions (41%) and indirect costs (68.6%) were the major cost drivers for total direct costs and the overall economic burden of lung cancer, respectively.

CONCLUSIONS

Our findings indicate per patient direct medical costs of small cell lung cancer and non-small-cell lung cancer to be substantial and comparable, indicating the substantial economic burden of lung cancer in terms of both direct and indirect costs. Our findings indicate that hospitalization/interventions cost item and indirect costs were the major cost drivers for total direct costs and the overall economic burden of lung cancer, respectively. Our findings emphasize the potential role of improved cancer prevention and early diagnosis strategies, by enabling cost savings related to drug treatment and metastasis management cost items, in sustainability of cancer treatments.

A probabilistic approach for economic evaluation of occupational health and safety interventions: a case study of silica exposure reduction interventions in the construction sector

BACKGROUND

Construction workers are at a high risk of exposure to various types of hazardous substances such as crystalline silica. Though multiple studies indicate the evidence regarding the effectiveness of different silica exposure reduction interventions in the construction sector, the decisions for selecting a specific silica exposure reduction intervention are best informed by an economic evaluation. Economic evaluation of interventions is subjected to uncertainties in practice, mostly due to the lack of precise data on important variables. In this study, we aim to identify the most cost-beneficial silica exposure reduction intervention for the construction sector under uncertain situations.

METHODS

We apply a probabilistic modeling approach that covers a large number of variables relevant to the cost of lung cancer, as well as the costs of silica exposure reduction interventions. To estimate the societal lifetime cost of lung cancer, we use an incidence cost approach. To estimate the net benefit of each intervention, we compare the expected cost of lung cancer cases averted, with expected cost of implementation of the intervention in one calendar year. Sensitivity analysis is used to quantify how different variables affect interventions net benefit.

RESULTS

A positive net benefit is expected for all considered interventions. The highest number of lung cancer cases are averted by combined use of wet method, local exhaust ventilation and personal protective equipment, about 107 cases, with expected net benefit of $45.9 million. Results also suggest that the level of exposure is an important determinant for the selection of the most cost-beneficial intervention.

CONCLUSIONS

This study provides important insights for decision makers about silica exposure reduction interventions in the construction sector. It also provides an overview of the potential advantages of using probabilistic modeling approach to undertake economic evaluations, particularly when researchers are confronted with a large number of uncertain variables.

Development, validation and results from the impact of treatment evolution in non-small cell lung cancer (iTEN) model

OBJECTIVES

Treatment of advanced NSCLC (aNSCLC) is rapidly evolving, as new targeted and immuno-oncology (I-O) treatments become available. The iTEN model was developed to predict the cost and survival benefits of changing aNSCLC treatment patterns from a Canadian healthcare system perspective. This report describes iTEN model development and validation.

MATERIALS & METHODS

A discrete event patient simulation of aNSCLC was developed. A modified Delphi process using Canadian clinical experts informed the development of treatment sequences that included commonly used, Health Canada approved treatments of aNSCLC. Treatment efficacy and the timing of progression and death were estimated from published Kaplan-Meier progression free and overall survival data. Costs (2018 CDN$) included were: drug acquisition and administration, imaging, monitoring, adverse events, physician visits, best supportive care, and end-of-life.

RESULTS AND CONCLUSION

Clinical validity of the iTEN model was assessed by comparing model survival predictions to published real-world evidence (RWE). Four RWE studies that reported the overall survival of patients treated with a broad sampling of common aNSCLC treatment patterns were used for validation. The validation coefficient of determination was R² = 0.95, with the model generally producing estimates that were neither optimistic nor conservative. The model estimated that current Canadian practice patterns yield a median survival of almost 13 months, a five-year survival rate of 3% and a life-time per-treated-patient cost of $110,806. Cost and survival estimates are presented and were found to vary by aNSCLC subtype. In conclusion, the iTEN model is a reliable tool for forecasting the impact on cost and survival of new treatments for aNSCLC.

End-of-Life Health-Care Cost of Patients With Lung Cancer: A Retrospective Study

Introduction:

Lung cancer exerts a significant societal and health-care–related economic burden and chemotherapy drugs constitute a major factor of total direct cost. The aim of the present study was to assess the direct health-care cost of lung cancer in Greece by conducting a retrospective analysis on the last 6 months of life.

Methods:

The present study was based on both the medical data and costs of treatment of deceased adult patients who suffered from terminal stage IIIB/IV lung cancer (non-small cell lung cancer and small cell lung cancer) during the last 6 months of their life. The study’s protocol was approved by the Hospital’s Research Ethics Committee. Costs included outpatient (outpatient services) and inpatient (inpatient services) costs. Descriptive statistics were mainly used for statistical analysis.

Results:

The files of 144 patients were analyzed. The total cost of health-care services for the study population during the last 6 months of life was attributed by 57% to inpatient services, whereas chemotherapy costs (74%) comprised the largest proportion of the total inpatient cost. The highest expenditure for outpatient services was attributed to concomitant medication (59%), followed by the cost of tests (21%) and radiotherapy (20%).

Conclusions:

The results of our study indicate that both inpatient and outpatient costs were substantial. The main inpatient and outpatient cost drivers were chemotherapy and concomitant medication, respectively. A more comprehensive nationwide study would be useful to validate our results and to include also indirect costs of cancer care in Greece.

A population-level comparison of cancer-related and non-cancer-related health care costs using publicly available provincial administrative data

Introduction

Costs associated with cancer care are increasing. Cancer costs in the context of other common non-cancer diagnoses have not been extensively studied at the population level. Knowledge from such analyses can inform health care resource allocation and highlight strategies to reduce overall costs.

Methods

Using cross-sectional data from publicly available population-level administrative data sources (health insurance claims, physician billing, and hospital discharge abstracts), we calculated incidence-adjusted health care costs (in 2014 Canadian dollars) for cancers and common non-cancer diagnoses in the adult population in a large Canadian province. Subgroup analyses were also performed for various provincial health administrative regions.

Results

Total costs related to cancer care amounted to $495 million for the province, of which at least $67 million (14%) was attributable to radiation and chemotherapy. Of the various cancer subtypes, hematologic malignancies were most costly at $70 million, accounting for 14% of the total cancer budget. Colon cancer followed at $51 million (10%), and lung cancer, at $44 million (9%). Cancer costs (with and without costs for radiation and chemotherapy) exceeded those for cardiovascular disease, diabetes mellitus, mental health, and trauma (p < 0.001). In addition, the costs of specific cancer subtypes varied by region, but hematologic and lung cancers were typically the most costly no matter the health region.

Conclusions

Using provincial administrative data to establish cost trends can help to inform health care allocation and budget decisions, and can facilitate comparisons between provinces.

Cost-of-illness study for non-small-cell lung cancer using real-world data

Background

With recent advances in the treatment of non-small-cell lung cancer (nsclc) and current fiscal constraints within publicly funded health care systems, understanding the real-world economic effect of lung cancer management has become important. The objective of the present study was to determine the costs and resources used in the management of nsclc cohorts in Ontario.

Methods

Patients diagnosed between 1 April 2010 and 31 March 2015 were identified in the Ontario Cancer Registry and linked to provincial administrative databases, capturing resources such as hospitalizations, cancer clinic visits, physician services, and systemic therapies or radiotherapy. A cost-of-illness analysis using a bottom-up approach and the GETCOST macro available at ices determined the overall total and mean costs in 2017 Canadian dollars. Resource utilization results were analyzed according to the total number of encounters per resource, the number of patients using each resource, and the number of encounters per patient. A separate cost-and-resource analysis was conducted for radiotherapy.

Results

The 24,729 nsclc patients identified included 4542 with stage iii unresectable disease and 10,103 with stage iv nonsquamous disease. The overall total cost for all nsclc patients was $1.9 billion, with inpatient hospitalizations ($635.2 million), cancer clinic visits ($323.7 million), and physician services ($301.4 million) being the top cost contributors. The mean cost per patient was $76,816. The total cost of radiotherapy was $38.5 million.

Conclusions

Real-world costs for the management of nsclc during the 5-year period examined were substantial, despite the fact that median survival was poor and treatment information was limited.

Resource Use and costs of End-Of-Life/Palliative Care: Ontario Adult Cancer Patients Dying during 2002 and 2003

The objective of this study is to estimate the direct medical cost of end-of-life and palliative (EOL/PAL) care for cancer patients during the last six months of their lives — or, during the period from diagnosis to death, if briefer — in 2002 and 2003, in Ontario, Canada. A linkage of cancer registry and administrative data is used to determine the costs of health care resources used during the EOL/PAL care period. Costs are analyzed by cancer diagnosis, location of death, and type of service. The total Ontario Ministry of Health-funded cost of EOL/PAL care for cancer patients is estimated to be about CAD$544 million per year, with an average per patient cost of about $25,000 in 2002–2003. Our results suggest that acute care consumes 75 percent of EOL/PAL funding and that only a small proportion of health care services used by EOL/PAL care cancer patients is likely to be formal palliative care.

The cost of hospital treatment of advanced stage lung cancer patients in a developing South East European country

Assessing the lung cancer treatment costs is necessary in order to estimate the budget impact of new interventions and therapeutic innovations. However, there are few studies regarding the use of resources and costs associated with treatment of lung cancer patients, not only in Serbia, but internationally. The aim of this paper was to assess the hospital costs of diagnosing and treating patients with stage IIIB and IV non-small cell lung cancer. Analysis of costs of care, services, medications and medical supplies, as well as of total hospital costs, was performed. Patients diagnosed with stage IIIB or IV NSCLC in the Institute during the year 2013 were enrolled in the study. A total of 187 patients with stage IIIB or IV NSCLC were analyzed. Total hospital costs were 506.970€, of which nearly two thirds was accounted to costs of services and medications. The mean cost per patient with adenocarcinoma was 3.075€, and for squamous cell lung carcinoma patient 1.943€. Statistically significant difference was shown when comparing mean hospital costs between patients in stage IIIB and stage IV adenocarcinoma, where this cost is higher in patients with stage IIIB. Mean hospital cost per female patient was nearly double as high that of the male patients, although without statistically significant difference. The mean cost for all adenocarcinoma patients was 1.317€, and for only four patients treated with TKI therapy 21.233€. This cost analysis could provide useful information in terms of budget impact of different lung cancer treatments and innovations in Serbia and corresponding developing countries.

Clinical and economic burden of idiopathic pulmonary fibrosis in Quebec, Canada

Background

Idiopathic pulmonary fibrosis (IPF), although rare, is a severe and costly disease.

Objective

To estimate the clinical and economic burden of IPF over multiple years before and after diagnosis using comprehensive administrative databases for the province of Quebec, Canada.

Methods

Several administrative databases from Quebec, providing information on hospital care, community care, and pharmaceuticals, were linked over a 5-year period ending March 31, 2011, which was before approval of antifibrotic drugs in Canada. Prevalent and incident IPF cases were defined using International Classification Disease-10-CA codes and International Classification Disease-9-CM codes. We used a broad definition that excluded cases with subsequent diagnosis of other interstitial lung diseases and a narrow definition that required further diagnostic testing to confirm IPF diagnosis. Incident cases had an IPF code in a particular year without any IPF code in the 2 previous years. Health care resource utilization before and after the index diagnosis date was determined and costs calculated. Costs were expressed in 2016 Canadian dollars.

Results

Over 5-years, 10,579 (mean age: 76.4; 58% male) satisfied the broad definition of IPF and 8,683 (mean age: 74.5; 57% male) satisfied the narrow definition (82% of broad). Incidences of IPF overall were 25.8 and 21.7/100,000 population for broad and narrow definitions, respectively. Three-year survival was 40% and 37% in broad and narrow cohorts, respectively. For both cohorts, health care resource utilization and costs increased several years before diagnosis ($2,721 and $7,049/patient 5 years and 2 years prior to diagnosis using a broad definition, respectively) and remained elevated for multiple years post diagnosis ($12,978 and $8,267 at 2 and 3 years postdiagnosis).

Conclusion

Health care resource utilization and costs of IPF increase many years prior to diagnosis. Incorporating multiyear annual costs before and after diagnosis results in a higher estimate of the economic burden of IPF than previous studies using a 1-year time frame.

Economic Burden for Lung Cancer Survivors in Urban China

BACKGROUND

With the rapid increase in the incidence and mortality of lung cancer, a growing number of lung cancer patients and their families are faced with a tremendous economic burden because of the high cost of treatment in China. This study was conducted to estimate the economic burden and patient responsibility of lung cancer patients and the impact of this burden on family income.

METHODS

This study uses data from a retrospective questionnaire survey conducted in 10 communities in urban China and includes 195 surviving lung cancer patients diagnosed over the previous five years. The calculation of direct economic burden included both direct medical and direct nonmedical costs. Indirect costs were calculated using the human capital approach, which measures the productivity lost for both patients and family caregivers. The price index was applied for the cost calculation.

RESULTS

The average economic burden from lung cancer was $43,336 per patient, of which the direct cost per capita was $42,540 (98.16%) and the indirect cost per capita was $795 (1.84%). Of the total direct medical costs, 35.66% was paid by the insurer and 9.84% was not covered by insurance. The economic burden for diagnosed lung cancer patients in the first year following diagnosis was $30,277 per capita, which accounted for 171% of the household annual income, a percentage that fell to 107% after subtracting the compensation from medical insurance.

CONCLUSIONS

The economic burden for lung cancer patients is substantial in the urban areas of China, and an effective control strategy to lower the cost is urgently needed.

Factors affecting hospital costs in lung cancer patients in the United Kingdom

INTRODUCTION

Rising healthcare costs and financial constraints are increasing pressure on healthcare budgets. There is little published data on the healthcare costs of lung cancer in the UK, with international studies mostly small and limited by data collection methods. Accurate assessment of healthcare costs is essential for effective service planning.

METHODS

We conducted a retrospective, descriptive cohort study linking clinical data from a local electronic database of lung cancer patients at a large UK teaching hospital with recorded hospital income. Costs were adjusted to 2013-2014 prices.

RESULTS

The study analysed secondary care costs of 3274 patients. Mean cumulative costs were £5852 (95% CI, £5694 to £6027) at 90 days and £10,009 (95% CI, £9717 to £10,278) at one year. The majority of costs (58.5%) were accumulated within the first 90 days, with acute inpatient costs the largest contributor at one year (42.1%). The strongest predictor of costs was active treatment, especially surgery. Costs were also affected by age, route to diagnosis, clinical stage and cell type.

DISCUSSION

Successful early diagnosis initiatives that increase radical treatment rates and improve outcomes may significantly increase the secondary care costs of lung cancer management. The use of routine NHS clinical and financial data can enable efficient and effective analyses of large cohort health economic data.

Trends in the Incidence of Lung Cancer Hospitalizations in Spain, 2001-2011

OBJECTIVE

To analyze changes in the incidence, diagnostic procedures, comorbidity, length of hospital stay and costs of patients hospitalized for lung cancer in Spain between 2001 and 2011.

PATIENTS AND METHODS

Retrospective study including all patients hospitalised with a primary diagnosis of lung cancer between 2001 and 2011. Data were collected from the National Hospital Discharge Database, encompassing the entire Spanish population. Economic and sociodemographic characteristics and health-related variables were analyzed.

RESULTS

A total of 298,435 hospitalizations occurred. The overall crude incidence increased from 61.18 per 100,000 inhabitants in 2001 to 65.08 per 100,000 in 2011 (P <.05), with a decrease in men and a proportionate increase in women. The age group with the highest incidence was 70 to 79 years. In 2001, 4.5% of patients had a Charlson comorbidity index (CCI) >2, and in 2011, prevalence of CCI >2 increased to 9.1% (P<.05). Mean length of hospital stay decreased during the study period. Computed tomography was the most common procedure. Mean cost per patient increased from €4,471.22 in 2001 to €5,562.54 (P<.05) in 2011. Factors related to the incidence of hospitalizations were age, sex and year of study in the multivariate analysis.

CONCLUSIONS

We found a decrease in the rate of hospitalizations in men and an increase in women, with a concomitant increase in comorbidities and cost; however, length of hospital stay decreased. Factors related to incidence of hospitalizations were age, sex and year of study.

Costs of non-small cell lung cancer in the Netherlands

OBJECTIVES

Real-world resource use and cost data on non-small cell lung cancer (NSCLC) are scarce. This data is needed to inform health-economic modelling to assess the impact of new diagnostic and/or treatment technologies. This study provides detailed insight into real-world medical resource use and costs of stage I-IV NSCLC in the Netherlands.

MATERIALS AND METHODS

A random sample of patients newly diagnosed with NSCLC (2009-2011) was selected from four Dutch hospitals. Data was retrospectively collected from patient charts. This data included patient characteristics, tumour characteristics, treatment details, adverse events, survival and resource use. Resource use was multiplied by Dutch unit costs expressed in EUR 2012. Total mean costs were corrected for censoring using the Bang and Tsiatis weighted complete-case estimator. Furthermore, costs of adverse events, costs per phase of NSCLC management and costs of second opinions are presented.

RESULTS

Data was collected on 1067 patients. Total mean costs for NSCLC diagnosis, treatment and follow-up are €28,468 during the study period and €33,143 when corrected for censoring. Adverse events were recorded in the patient charts for 369 patients (41%) and 82 patients (9%) experienced an adverse event of grade III or higher. For these patients, adverse event-related hospital admissions cost on average €2,091. Mean total costs are €1,725 for the diagnostic period, €17,296 for first treatment line, and €13,236 for each later treatment line. Costs of providing a second opinion are €2,580 per patient.

CONCLUSIONS

Total mean hospital costs per NSCLC patient are €33,143 for the total duration of the disease. Ignoring censoring in our data underestimates these costs by 14%. Main limitations of the study relate to the short follow-up time, staging difficulties and missing data. Its main strength is that it provides highly detailed, real-world data on the costs of NSCLC.

Cost-components of lung cancer care within the first three years after initial diagnosis in context of different treatment regimens

OBJECTIVES

Although lung cancer is of high epidemiological relevance in Germany, evidence on its economic implications is scarce. Sound understanding of current care structures and associated expenditures is required to comprehensively judge the additional benefit of novel interventions in lung cancer care. Adopting a payer perspective, our study aims to analyze expenditures for individuals with incident lung cancer.

MATERIAL AND METHODS

Patients with an initial diagnosis of lung cancer (ICD-10 code C34) in 2009 were searched in a large, nationwide base of health insurance claims data and grouped according to initial treatment (Surgery, Chemotherapy/Radiotherapy, No specific treatment). All-cause SHI and lung cancer-related spending was assessed for a patient-individual three-year time frame after initial diagnosis. Expenditures per case and expenditures per year survived were calculated via Generalized Linear Gamma Models adjusted for age, gender, living region, baseline metastases, multiple tumors and initial treatment regimen using time under observation as a weighting factor.

RESULTS

17,478 individuals were identified. Lung cancer-related expenditures peaked within the first six months after initial diagnosis. Following, they declined subsequently and so did their share in all-cause SHI spending. Lung cancer-related expenditures per case were estimated at €20,400 (53% of all-cause expenditures) with a huge variance according to initial treatment regimen [

SURGERY

€20,400, Chemotherapy/Radiotherapy: €26,300, No specific treatment: €4200]. Cost per year survived amounted to €15,500 (55% of all cause expenditures) [

SURGERY

€11,600, Chemotherapy/Radiotherapy: €20,200, No specific treatment: €7600].

CONCLUSION

Analyses of lung cancer-related expenditures need to take into account treatment strategies and survival. Our study is representative for a large share of the population and provides detailed, patient-level information on costs of care and their compilation. Results render estimates available for the cost of lung cancer e.g. for budget impact analyses, cost-effectiveness analyses of screening and prevention schemes, or prognostic models of life-time expenditures per lung cancer case.

Estimating the direct and indirect costs of lung cancer: a prospective analysis in a Greek University Pulmonary Department

BACKGROUND

Lung cancer (LC) is a disease with high morbidity and mortality while the prevention and treatment constitutes a significant financial burden. This economic burden has an increasing trend, with hospitalization being the highest cost factor in most studies, while the patients' quality of life (QoL) and response to treatment is not proven to be positively affected.

OBJECTIVE

To evaluate the direct and indirect cost of managing patients with LC in Greece according to stage and histological type of cancer, total chemotherapy cycles, age, gender, smoking habit, overall survival (OS), treatment outcome (TO) and QoL.

METHODS

One hundred thirteen of 128 consecutive patients met the inclusion criteria and were included in this prospective study. Patient enrolment started in August 2011 and ended in November 2011. The duration of the patient follow up was 32 months after diagnosis until end of registry. Total direct cost included diagnosis and treatment cost. Indirect cost constituted of patient's and family caregivers lost days of productivity. QoL was assessed with EORTC-QLQ-30 and Lung Cancer Symptom Scale (LCSS) questionnaires before treatment and every three months.

RESULTS

Total direct cost was €1,853,984 and chemotherapy drugs was the highest cost factor (€1,216,421). Total indirect cost was 28,774 days of which 27,293 were related to patients. Total direct cost was significantly related to the increased number of total chemotherapy cycles, longer OS, histological type of adenocarcinoma, female gender and younger patients. No relation was found between total indirect cost and the above factors. When the association between total direct/indirect cost and QoL was examined no significant results were drawn.

CONCLUSIONS

The burden of LC on health care systems remains very high and was associated with the increased number of total chemotherapy cycles, longer OS, adenocarcinoma histological type of cancer, female gender and younger patients. Chemotherapy drugs constituted the higher factor of total direct cost. Indirect cost was considerably higher for patients than family caregivers and did not significantly differ in relation to the above factors. No significant conclusion was drawn regarding QoL and total direct/indirect cost.

Estimation of lung cancer diagnosis and treatment costs based on a patient-level analysis in Catalonia (Spain)

BACKGROUND

Assessing of the costs of treating disease is necessary to demonstrate cost-effectiveness and to estimate the budget impact of new interventions and therapeutic innovations. However, there are few comprehensive studies on resource use and costs associated with lung cancer patients in clinical practice in Spain or internationally. The aim of this paper was to assess the hospital cost associated with lung cancer diagnosis and treatment by histology, type of cost and stage at diagnosis in the Spanish National Health Service.

METHODS

A retrospective, descriptive analysis on resource use and a direct medical cost analysis were performed. Resource utilisation data were collected by means of patient files from nine teaching hospitals. From a hospital budget impact perspective, the aggregate and mean costs per patient were calculated over the first three years following diagnosis or up to death. Both aggregate and mean costs per patient were analysed by histology, stage at diagnosis and cost type.

RESULTS

A total of 232 cases of lung cancer were analysed, of which 74.1% corresponded to non-small cell lung cancer (NSCLC) and 11.2% to small cell lung cancer (SCLC); 14.7% had no cytohistologic confirmation. The mean cost per patient in NSCLC ranged from 13,218 Euros in Stage III to 16,120 Euros in Stage II. The main cost components were chemotherapy (29.5%) and surgery (22.8%). Advanced disease stages were associated with a decrease in the relative weight of surgical and inpatient care costs but an increase in chemotherapy costs. In SCLC patients, the mean cost per patient was 15,418 Euros for limited disease and 12,482 Euros for extensive disease. The main cost components were chemotherapy (36.1%) and other inpatient costs (28.7%). In both groups, the Kruskall-Wallis test did not show statistically significant differences in mean cost per patient between stages.

CONCLUSIONS

This study provides the costs of lung cancer treatment based on patient file reviews, with chemotherapy and surgery accounting for the major components of costs. This cost analysis is a baseline study that will provide a useful source of information for future studies on cost-effectiveness and on the budget impact of different therapeutic innovations in Spain.

Cost-effectiveness of chemotherapy combined with thoracic radiotherapy versus chemotherapy alone for limited stage small cell lung cancer: A population-based propensity-score matched analysis

BACKGROUND

The addition of thoracic radiotherapy improves the outcome of limited stage small cell lung cancer (LS-SCLC), however, the cost-effectiveness of this process has never been reported. We aimed to estimate the short-term cost-effectiveness of chemotherapy combined with thoracic radiotherapy (C-TRT) versus chemotherapy alone (C/T) for LS-SCLC patients from the payer's perspective (Taiwan National Health Insurance).

METHODS

We identified LS-SCLC patients diagnosed within 2007-2009 through a comprehensive population-based database containing cancer and death registries, and reimbursement data. The duration of interest was one year within diagnosis. We included potential confounding covariables through literature searching and our own experience, and used a propensity score to construct a 1:1 population for adjustment. We used a net benefit (NB) approach to evaluate the cost-effectiveness at various willingness-to-pay (WTP) levels. Sensitivity analysis regarding potential unmeasured confounder(s) was performed.

RESULTS

Our study population constituted 74 patients. The mean cost (2013 USD) and survival (year) was higher for C-TRT (42 439 vs. 28 357; 0.94 vs. 0.88). At the common WTP level (50 000 USD/life-year), C-TRT was not cost effective (incremental NB - 11 082) and the probability for C-TRT to be cost effective (i.e. positive net benefit) was 0.005. The result was moderately sensitive to potential unmeasured confounder(s) in sensitivity analysis.

CONCLUSIONS

We provide evidence that when compared to C/T, C-TRT is effective in improving survival, but is not cost-effective in the short-term at a common WTP level from a payer's perspective. This information should be considered by clinicians when discussing thoracic radiotherapy with their LS-SCLC patients.

First data on direct costs of lung cancer management in Morocco

BACKGROUND

Lung cancer is the leading cause of cancer morbidity and mortality. Its management has a significant economic impact on society. Despite a high incidence of cancer, so far, there is no national register for this disease in Morocco. The main goal of this report was to estimate the medical costs of lung cancer in our country.

METHODS

We first estimated the number of annual new cases according to stage of the disease on the basis of the Grand-Casablanca-Region Cancer Registry data. For each sub-group, the protocol of treatment was described taking into account the international guidelines, and an evaluation of individual costs during the first year following diagnosis was made. Extrapolation of the results to the whole country was used to calculate the total annual cost of treatments for lung cancer in Morocco.

RESULTS

Overall approximately 3,500 new cases of lung cancer occur each year in the country. Stages I and II account for only 4% of cases, while 96% are diagnosed at locally advanced or metastatic stages III and IV. The total medical cost of lung cancer in Morocco is estimated to be around USD 12 million. This cost represents approximately 1% of the global budget of the Health Department. According to AROME Guidelines, about 86% of the newly diagnosed lung cancer cases needed palliative treatment while 14% required curative intent therapy. The total cost of early and advanced stages lung cancer management during the first year were estimated to be 4,600 and 3,420 USD, respectively.

CONCLUSION

This study provides health decision-makers with a first estimate of costs and the opportunity to achieve the optimal use of available data to estimate the needs of health facilities in Morocco. A substantial proportion of the burden of lung cancer could be prevented through the application of existing cancer control knowledge and by implementing tobacco control programs.

Cost analysis of lung cancer management in South Western Sydney

INTRODUCTION

Lung cancer is the leading cause of cancer mortality in Western nations, and associated health-care costs are escalating. The aim of this study was to describe the current pattern of resource use and direct medical costs associated in managing lung cancer in South Western Sydney, Australia.

METHODS

All new cases of primary lung carcinoma discussed at the Liverpool and Macarthur Cancer Therapy Centre (CTC) Lung Cancer Multidisciplinary Team meeting or seen at CTC between 1 December 2005 and 21 December 2006 were reviewed. Staging investigations, hospitalisation, treatment and follow-up investigations were documented from first consultation to last follow-up (31 October 2008 or death). Cost estimates were based on the Australian Medicare Benefits Schedule and reported in Australian dollars. Infrastructure, staff and non-medical costs were excluded.

RESULTS

There were 210 patients, median age 68.2 years (range 39-90) with median follow-up of 16.6 months. The pathology and stage distribution were: 3.8% limited stage small cell lung cancer (SCLC), 10.0% extensive stage SCLC, 13.4% stage I and II non-small cell lung cancer (NSCLC), 28.5% stage III NSCLC and 44.3% stage IV NSCLC. The estimated total cost for managing this patient cohort was A$2.91 million. The cost components were: staging investigations (10.1%), treatment 41.2% (2.8% surgery, 15.8% radiotherapy and 22.6% chemotherapy), hospitalisation (43.7%) and follow-up investigations (5%). The median costs for managing NSCLC and SCLC subgroups were A$10,675 (range A$669-612,789) and A$14,799 (range A$908-31,057), respectively.

CONCLUSION

Hospitalisation and cancer treatment, particularly chemotherapy, accounted for the major components of direct medical costs in the management of lung cancer.

Impact of initial pattern of care on hospital costs in a cohort of incident lung cancer cases

RATIONALE, AIMS AND OBJECTIVES

Lung cancer is a disease with high consumption of health care resources. The aim of this study was to describe hospital costs due to lung cancer care from diagnosis until death or end of the study follow-up, in a cohort of incident cases, by using administrative data.

METHODS

Particular attention was given to the determinants of total costs and the impact of the initial treatment approach on the process of costs accumulation. Incident cases were identified by the local Cancer Registry (January 2000-December 2003) among the residents of Turin (Italy). Per patient hospital care has been determined from administrative databases (outpatient radiotherapy records and hospital discharge records). Costs determinants were identified via a multivariable generalized linear model (GLM), with a Gamma cost distribution and a logarithmic link function. To assess the time effect over the cost accumulation process for non-small-cell lung cancer cases, the same GLM Gamma model was repeated at different follow-up periods. Analyses were stratified by cancer histotype.

RESULTS

Results evidenced the relevant role of initial patterns of care on the cost accumulation process, with increased midterm costs associated with curative patterns of care.

CONCLUSION

The use of administrative data enabled hospital lung cancer care to be described, and related costs to be estimated.

Economic analysis: randomized placebo-controlled clinical trial of erlotinib in advanced non-small cell lung cancer

BACKGROUND

The NCIC Clinical Trials Group conducted the BR.21 trial, a randomized placebo-controlled trial of erlotinib (an epidermal growth factor receptor tyrosine kinase inhibitor) in patients with previously treated advanced non-small cell lung cancer. This trial accrued patients between August 14, 2001, and January 31, 2003, and found that overall survival and quality of life were improved in the erlotinib arm than in the placebo arm. However, funding restrictions limit access to erlotinib in many countries. We undertook an economic analysis of erlotinib treatment in this trial and explored different molecular and clinical predictors of outcome to determine the cost-effectiveness of treating various populations with erlotinib.

METHODS

Resource utilization was determined from individual patient data in the BR.21 trial database. The trial recruited 731 patients (488 in the erlotinib arm and 243 in the placebo arm). Costs arising from erlotinib treatment, diagnostic tests, outpatient visits, acute hospitalization, adverse events, lung cancer-related concomitant medications, transfusions, and radiation therapy were captured. The incremental cost-effectiveness ratio was calculated as the ratio of incremental cost (in 2007 Canadian dollars) to incremental effectiveness (life-years gained). In exploratory analyses, we evaluated the benefits of treatment in selected subgroups to determine the impact on the incremental cost-effectiveness ratio.

RESULTS

The incremental cost-effectiveness ratio for erlotinib treatment in the BR.21 trial population was $94,638 per life-year gained (95% confidence interval = $52,359 to $429,148). The major drivers of cost-effectiveness included the magnitude of survival benefit and erlotinib cost. Subgroup analyses revealed that erlotinib may be more cost-effective in never-smokers or patients with high EGFR gene copy number.

CONCLUSION

With an incremental cost-effectiveness ratio of $94 638 per life-year gained, erlotinib treatment for patients with previously treated advanced non-small cell lung cancer is marginally cost-effective. The use of molecular predictors of benefit for targeted agents may help identify more or less cost-effective subgroups for treatment.

Costs for tuberculosis care in Canada

OBJECTIVES

We have estimated tuberculosis (TB)-related expenditures by governments and other third parties in Canada in 2004, in order to compare spending on different activities, by various jurisdictions, and in different regions.

METHODS

To ascertain health system costs (including public health costs), a self-administered questionnaire was completed by all federal, provincial, and territorial health departments and laboratories involved in TB activities and a sample of local health departments. Hospitalization information was obtained from the Canadian Institute for Health Information, while costs for care were derived from published literature. Costs borne by patients and families were not included. All costs were ascertained for 2004 and expressed in Canadian dollars.

RESULTS

In 2004, total TB-related expenditures in Canada were $74 million, equivalent to $47,290 for every active TB case diagnosed in that year. Research accounted for $4.5 million (or 6% of the total). Non-research-related federal spending accounted for $16.3 million (22%) and provincial/territorial expenditures accounted for $53.1 million (72%). Active tuberculosis accounted for $31 million or 59% of provincial/territorial expenditures. There were substantial regional differences in TB-related expenditures; the highest expenditures were in the Northern Territories ($72,441 per active TB case), followed by the four Western provinces ($35,914), and lowest in the Atlantic provinces ($28,259).

CONCLUSIONS

Total TB-related expenditures in Canada in 2004 were considerable, of which almost 60% were for curative services and only 40% for prevention and control activities. Regional differences likely reflect differences in accessibility of the populations to health care services, and greater interventions in communities with ongoing TB transmission.
