Costs of care associated with non-small-cell lung cancer in a commercially insured cohort

Economic burden of early-stage non-small-cell lung cancer: an assessment of healthcare resource utilization and medical costs

Aim: To quantify the economic burden of early-stage non-small-cell lung cancer (NSCLC) among patients with and without adjuvant therapy. Methods: All-cause and NSCLC-related healthcare resource utilization and medical costs were assessed among patients with resected stage IB-IIIA NSCLC in the SEER-Medicare database (1 January 2011-31 December 2019), from NSCLC diagnosis to death, end of continuous enrollment, or end of data availability (whichever occurred first). Results: Patients receiving adjuvant therapy had the lowest mean NSCLC-related medical costs (adjuvant [n = 1776]: $3738; neoadjuvant [n = 56]: $5793; both [n = 47]: $4818; surgery alone [n = 3478]: $4892, per-person-per-month), driven by lower NSCLC-related hospitalization rates. Conclusion: Post-surgical management of early-stage NSCLC was associated with high economic burden. Adjuvant therapy was associated with numerically lower medical costs over surgical resection alone.

Cost of Tobacco-related Cancer Hospitalizations in the U.S., 2014

INTRODUCTION

Smoking has been causally linked to 12 tobacco-related cancers: oral cavity and pharynx, esophagus, stomach, colon and rectum, liver, pancreas, larynx, lung, cervix, bladder, kidney, and acute myeloid leukemia. Tobacco-related cancers-related morbidity and mortality have been well described, but little is known about the prevalence of tobacco-related cancer hospitalizations and associated costs. This study estimates the annual number of tobacco-related cancer hospitalizations and their associated direct medical costs in the U.S.

METHODS

This study examined data from the 2014 National Inpatient Sample, the largest publicly available all-payer inpatient care database in the U.S. The authors calculated number of hospitalizations, total costs, length of stay, and cost per stay for tobacco-related cancer hospitalizations and cancer hospitalizations not related to tobacco.

RESULTS

In 2014, there were an estimated 461,295 annual tobacco-related cancer hospitalizations at a cost of $8.2 billion in the U.S. Tobacco-related cancers accounted for 45% of total cancer hospitalizations and cancer hospitalization costs. Compared with cancer hospitalizations not related to tobacco, tobacco-related cancer hospitalizations had a longer mean length of stay (6.8 vs 5.7 days).

CONCLUSIONS

The burden of tobacco-related cancer hospitalizations is substantial in the U.S. These findings highlight the importance of tobacco prevention and cessation efforts to decrease the burden of tobacco-related cancers in the U.S.

Costs, Trends, and Related Factors in Treating Lung Cancer Patients in 67 Hospitals in Guangxi, China

Lung cancer is a common disease with high mortality in China. Recent economic advances have led to improved medical capabilities, while costs associated with treating this disease have increased. Such change contributes to a commonly held belief that healthcare costs are out of control. However, few studies have examined this issue. Here, we use 34,678 hospitalization summary reports from 67 Guangxi hospitals (period 2013-2016) to document costs, temporal trends, and associated factors. Findings from this study are surprising in that they debunk the myth of uncontrolled healthcare costs. In addition, results and experiences from Guangxi are informative for other comparable regions.

An international comparison of costs of end-of-life care for advanced lung cancer patients using health administrative data

BACKGROUND

Patterns of end-of-life cancer care differ in Canada and the United States; yet little is known about differences in service-specific and overall costs.

AIM

The aim of this study was to compare end-of-life costs in Ontario, Canada, and the United States, using administrative health data.

DESIGN

Advanced-stage nonsmall cell lung cancer patients who died from cancer at age ⩾ 65.5 years in 2001-2005 were selected from the US Surveillance, Epidemiology, and End Results-Medicare database (N = 16,858) and the Ontario Cancer Registry (N = 8643). We estimated total and service-specific costs (2009 US dollars) in each of the last 6 months of life from the public payer perspectives for short-term and long-term survivors (lived < 180 and ⩾ 180 days post-diagnosis, respectively). Services were defined for comparisons between systems.

RESULTS

Mean monthly costs increased as death approached, were higher in short-term than long-term survivors, and were generally higher in the United States than in Ontario until the month before death, when they were similar (long-term survivors: US$10,464 and US$10,094 (p = 0.53), short-term survivors US$14,455 and US$12,836 (p = 0.11), in Surveillance, Epidemiology, and End Results-Medicare and Ontario, respectively). Costs for Medicare hospice and Ontario's palliative care components were similar and increased closer to death. Inpatient hospitalization was the main cost driver with similar costs in both cohorts, despite lower utilization in the United States. The compositions of many services and costs differed.

CONCLUSION

Costs for nonsmall cell lung cancer patients were slightly higher in the United States than Ontario until 1 month before death. Administrative data allow exploration and international comparisons of reimbursement policies, health-care delivery, and costs at the end of life.

Cost-effectiveness of denosumab versus zoledronic acid in the management of skeletal metastases secondary to breast cancer

BACKGROUND

Denosumab has been approved in the United States for the prevention of skeletal-related events (SREs) in metastatic breast cancer. In a Phase III trial in patients with bone-metastatic breast cancer (N = 2033), denosumab was associated with a significantly delayed time to first SRE (by 18%; P < 0.001 noninferiority; P = 0.01 superiority) and time to first and subsequent SREs (by 23%; P = 0.001). Overall survival (HR = 0.95; 95% CI, 0.81-1.11; P = 0.49) and disease progression (HR = 1.00; 95% CI, 0.89-1.11; P = 0.93) did not differ significantly between groups. Denosumab was associated with a nonsignificant reduction in serious adverse events (44.4% vs 46.5%).

OBJECTIVES

Given the current ambiguity regarding the cost-effectiveness of these agents in light of these trial outcomes, the present analysis assessed, from a US payer perspective, the cost-effectiveness of denosumab versus zoledronic acid in patients with bone metastases secondary to breast cancer.

METHODS

A literature-based Markov model was developed to estimate the survival, quality-adjusted life-years (QALYs) gained, number and costs of SREs, and drug and administration costs in patients receiving denosumab or zoledronic acid over 27 and 60 months. Clinical inputs reproduced the trial outcomes. SRE-related costs and utilities were literature based. Costs and QALYs were discounted 3% annually.

RESULTS

In the 27-month base-case analysis, denosumab was associated with fewer SREs (-0.298), more QALYs (+0.0102), and lower SRE-related costs (-$2016), but higher drug-related (+$9123) and total costs (+$7107) versus zoledronic acid. The cost per QALY gained (ie, incremental cost-effectiveness ratio [ICER]) was $697,499. In sensitivity analyses, the ICER ranged from $192,472 to $1,340,901/QALY, depending on assumptions regarding treatment benefits, drug costs, and analytical horizon. In the probabilistic sensitivity analysis, denosumab was cost-effective in 2 of 5000 modeled replicates (0.04%).

CONCLUSIONS

Despite the limitations of restricted availability of clinical data and uncertainty regarding the price of generic zoledronic acid, the findings from the present analysis suggest that the use of denosumab is associated with a high ICER compared with zoledronic acid. This finding may raise important questions regarding the economic value of denosumab in bone-metastatic breast 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.

Cost-effectiveness of zoledronic acid in the management of skeletal metastases in patients with lung cancer in France, Germany, Portugal, the Netherlands, and the United kingdom

BACKGROUND

Zoledronic acid (ZOL) significantly reduces the risk of new skeletal-related events (SREs) in patients with non-small cell lung cancer (NSCLC) who have bone metastases.

OBJECTIVE

The purpose of this study was to assess the cost and cost-effectiveness of ZOL in the management of skeletal metastases in this population across 5 European countries (France, Germany, United Kingdom, Portugal, and the Netherlands) from the perspective of national health care.

METHODS

This cost-effectiveness analysis was based on a subset of patients with NSCLC who were enrolled in a Phase III trial of patients with bone metastases secondary to a variety of solid tumors. In this trial, patients were randomized to receive ZOL or placebo every 3 weeks for up to 21 months. Survival, SRE incidence, and number of infusions administered were derived from the clinical trial. Costs of SREs were estimated using hospital Diagnosis Related Group tariffs and published data. Drug, drug administration, and supply costs were obtained from published and internet sources. Quality-adjusted life-years (QALYs) were estimated based on the published utilities and modeled survival and frequency of SREs. Uncertainty surrounding outcomes was addressed via univariate and probabilistic sensitivity analyses.

RESULTS

Compared with patients receiving placebo (n = 120), patients receiving ZOL (n = 124) experienced an estimated 0.79 fewer SREs and gained an estimated 0.02 QALYs. ZOL use in patients with NSCLC and bone metastases was associated with a reduction in SRE costs (ranging from €1547 to €1893 [2007-2008 €], depending on the country). After adding drug and drug administration costs, ZOL use resulted in a net savings of €288 per patient in Germany, €209 in the United Kingdom, and €113 in Portugal. In France and the Netherlands, costs increased (€17 and €178, respectively), but the costs per QALY gained were low (€786 and €8278, respectively). In univariate sensitivity analyses, the cost per QALY for ZOL versus placebo was ≤€50,000 for all scenarios tested. The results were most sensitive to assumptions regarding survival, number of ZOL infusions, and the costs of SREs. The probabilistic sensitivity analysis indicated that ZOL cost ≤€50,000 per QALY in 65% to 83% of model simulations (depending on country). However, some degree of uncertainty remained as the 95th percentile of cost per QALY was high.

CONCLUSIONS

This analysis is subject to the usual limitations of cost-effectiveness models, which combine assumptions and data from multiple sources. Nevertheless, based on the assumptions used herein, the present model suggests that ZOL increases QALYs and is cost saving and/or cost effective compared with placebo in patients with NSCLC in France, Germany, the United Kingdom, Portugal, and the Netherlands.

Analysis of wait times and costs during the peri-diagnostic period for non-small cell lung cancer

PURPOSE

To determine the wait times and healthcare costs around the time of non-small cell lung cancer (NSCLC) diagnosis for a large, population-based cohort of patients.

METHODS

Data on baseline demographics, diagnostic and staging tests, timelines of investigations, and frequency of physician visits and hospital admissions were obtained from a provincial cancer registry and health administrative databases for 2852 patients, who were diagnosed with NSCLC from 1996 to 2000 in Manitoba, Canada. Dates between investigations were used to determine wait times surrounding diagnosis and fee codes for physician and hospital services were used to estimate costs.

RESULTS

The median wait times from chest x-ray to chest computed tomography (CT) scan and from CT scan to definitive histological diagnosis were 8 (inter-quartile range 1-25) and 18 (inter-quartile range 3-42) days, respectively. At least 25% of patients waited more than 55 days from initial suspicion on chest x-ray to final diagnosis of NSCLC. The mean cost per case of NSCLC diagnosis was $6,978 (in Canadian dollars) where the majority of expenses was attributed to hospital admissions and repeated physician visits before a diagnosis was confirmed.

CONCLUSIONS

Despite clinical suspicion for NSCLC, a significant number of patients wait more than 8 weeks for a definitive diagnosis. Substantial costs are incurred by the Canadian universal healthcare system in the months surrounding diagnosis. Establishment of more efficient and cost-effective healthcare delivery in the peri-diagnostic time period may benefit the system as well as the patients.

Cost and outcomes of patients with solitary pulmonary nodules managed with PET scans

BACKGROUND

No prior study to our knowledge has observed the cost of managing solitary pulmonary nodules of patient groups defined by PET scan results.

METHODS

We combined study and administrative data over 2 years of follow-up.

RESULTS

Of 375 individuals with a definitive diagnosis, 54.4% had a malignant nodule and 62.1% had positive PET scan results. Mortality risk was 5.0 times higher (CI, 3.1-8.2) and cost was greater (50,233 dollars vs 22,461 dollars, P<.0001) among patients with malignant nodule. Mortality risk was 4.1 times higher (CI, 2.4-7.0) and cost was greater (47,823 dollars vs 20,744 dollars, P<.0001) among patients with a positive PET scan result. Among patients with a malignant nodule, 4.9% had a false-negative PET scan, but cost and survival were not different from true positives. Among patients with a benign nodule, 22.8% had a false-positive PET scan. These patients had greater cost (33,783 dollars vs 19,115 dollars, P<.01), more surgeries and biopsies, and 3.8 times the mortality risk (CI, 1.6-9.2) of true negatives. Just over one-half (54.5%) of individuals with positive PET scans received surgery. Most individuals with negative PET scans (85.2%) were managed by watchful waiting. They incurred fewer costs than patients with negative PET scans who were managed more aggressively (19,378 dollars vs 28,611 dollars, P<.01).

CONCLUSIONS

Management of solitary pulmonary nodules is expensive, especially if the nodule is malignant or if the PET scan result is false positive. Among patients with malignant nodules, 2-year survival is poor. Compared with true-positive PET scan results, false-negative results are not associated with lower costs or better outcomes.

Costs of first-line doublet chemotherapy and lifetime medical care in advanced non-small-cell lung cancer in the United States

OBJECTIVES

The purpose of this study was to identify total lifetime medical-care costs and costs associated with first-line chemotherapy treatment among older patients with stage IIIB/IV non-small-cell lung cancer treated with commonly used two-drug chemotherapy ("doublet") regimens in the United States.

METHODS

Study patients included individuals aged 65 years and older who received a diagnosis of stage IIIB/IV non-small-cell lung cancer in a Surveillance, Epidemiology and End Results cancer registry between 1997 and 2002 and who received first-line treatment with commonly used doublet regimens. Patients were followed retrospectively in the Surveillance, Epidemiology and End Results-Medicare database to evaluate lifetime medical-care costs and costs while on first-line chemotherapy treatment. Pairwise comparisons of treatment costs were estimated by using nonparametric bootstrap methods.

RESULTS

Lifetime medical-care costs totaled approximately $70,000 and on-treatment costs for first-line chemotherapy totaled approximately $30,000 among study patients and were dominated by hospitalization and physician costs. Lifetime costs were significantly higher among patients treated with first-line cisplatin/carboplatin (platinum) plus a taxane compared with those who received platinum plus gemcitabine [difference: $4781 ($1558-$8039)] or other doublet therapy [difference: $5961 ($2333-$9614)]. Total on-treatment costs for first-line chemotherapy were significantly higher among patients treated with platinum plus a taxane compared with those who received platinum plus gemcitabine [difference: $5825 ($3872-$7770)], platinum plus another agent [difference: $5968 ($3995-$7975)], or another doublet therapy [difference: $3663 ($1620-$5740)].

CONCLUSIONS

There is a cost differential between first-line doublet regimens in terms of lifetime and on-treatment costs. Although doublet therapy with platinum and a taxane was the most frequently utilized regimen, it was associated with the highest lifetime and on-treatment costs.

Screening for lung cancer

OBJECTIVE

The purpose of our review is to discuss the current state of lung cancer screening using CT in the context of defined criteria for effective screening.

CONCLUSION

Although there are hopeful developments in lung cancer screening, a number of unresolved issues must be answered before adopting screening on a large scale. Currently no data exist to suggest that lung cancer screening with CT will result in a decrease in lung cancer mortality.

Costs of cancer care in the USA: a descriptive review

Although many studies assessing the cost of cancer care have been conducted in the US, to date, these studies and the underlying methods used to estimate costs have not been reviewed systematically. We conducted a descriptive review of the published literature on the cost of cancer care in the US, and identified 60 papers published between 1995 and 2006 pertinent to our study. We found heterogeneity across the studies in terms of the settings, populations studied, measurement of costs, and study methods. We also identified limitations in the generalizability of findings, the misclassification of patient groups and costs, and concerns with study methods. Among studies that reported costs of cancer care in multiple phases of care and for multiple tumor sites, costs were generally highest in the initial year following diagnosis and the last year of life, and lower in the continuing phase (i.e. the period between the initial and last year of life phases), following a 'u-shaped' curve. Within phase of care, costs for lung and colorectal cancer care were generally higher than those for breast and prostate cancer care, however, the long-term or lifetime costs for each type of cancer were more similar, reflecting the differences in survival and costs in each phase between the different disease types.

Informal caregiving burden in advanced non-small cell lung cancer: the HABIT study

INTRODUCTION

This study's aim was to assess economic data regarding the home assistance burden for advanced non-small cell lung cancer (NSCLC) patients in Italy.

PATIENTS AND METHODS

One hundred four NSCLC patients in second-line chemotherapy (2LC) or in supportive therapy (ST) were enrolled in 18 Italian oncology departments and were observed for 3 months. The main caregiver's workload was assessed monthly by a task scale; other caregivers' activities were also registered. Eastern Cooperative Oncology Group performance status was assessed by physicians, and patients completed the Lung Cancer Symptoms (LCS) subscale. Formal caregiving time was valued according to market prices; informal caregiving hours were valued using the wage rate for an equivalent service. Covariance analysis was performed to check for influential factors in assistance costs.

RESULTS

The mean age of the total sample was 65.5 years, and prevalence of males was over 80%. In over 70% of cases, the principal caregiver was patient's spouse, living with the patient and not working. Principal caregiver support was the main cost item: 2.368 euros in 2LC and 2.805 euros in ST, representing 74% of total trimonthly assistance costs. Regression analysis showed a positive correlation between the severity of symptoms and the costs of assistance. The caregiving burden was higher in patients with bone and/or cerebral metastases; other metastasis sites seemed to have no impact on assistance costs.

CONCLUSION

Considering quality of life as the ultimate health outcome, clinicians are challenged to contribute to a research and policy agenda that holds burden of care in due consideration.

Cost-minimization analysis of a phase III trial comparing concurrent versus sequential radiochemotherapy for locally advanced non-small-cell lung cancer (GFPC-GLOT 95–01)

BACKGROUND

We conducted an economic analysis of a phase III clinical trial comparing sequential radiochemotherapy (RT-CT) with concurrent RT-CT in patients with locally advanced non-small-cell lung cancer.

PATIENTS AND METHODS

The trial was a randomized multicenter study comparing three cycles of chemotherapy (arm A) followed by radiotherapy against an RT-CT combination (two cycles of platinum etoposide) followed by two cycles of platinum-vinorelbine (arm B). The economic analysis adopted the payer's perspective and only included direct costs. Costs (euro, 1996-2003) were recorded until the cut-off date. A cost minimization analysis and a sensitivity analysis were carried out.

RESULTS

Data from 173 patients were used in the economic study. Protocol costs tended to be higher in arm B, while relapse costs were significantly higher in arm A. The total number of hospital days was higher in arm B. The average total cost per patient was euro16,074 in arm A and euro15,245 in arm B (P=0.15). The cost minimization analysis favored arm B. This advantage persisted in the sensitivity analysis.

CONCLUSIONS

Concurrent RT-CT was not the more costly strategy in this phase III trial, despite lengthier hospitalization for toxicity. Other studies of similar design are needed to confirm these results in future randomized trials.

Shelter-based palliative care for the homeless terminally ill

BACKGROUND

The homeless have high rates of mortality, but live in environments not conducive to terminal care. Traditional palliative care hospitals may be reluctant to accept such patients, due to behavior or lifestyle concerns. The Ottawa Inner City Health Project (OICHP) is a pilot study to improve health care delivery to homeless adults. This is a retrospective analysis of a cohort of terminally ill homeless individuals and the effectiveness of shelter-based palliative care. As proof of principle, a cost comparison was performed.

METHODS

28 consecutive homeless terminally ill patients were admitted and died at a shelter-based palliative care hospice. Demographics, diagnoses at admission and course were recorded. Burden of illness was assessed by medical and psychiatric diagnoses, addictions, Karnofsky scale and symptom management. An expert panel was convened to identify alternate care locations. Using standard costing scales, direct versus alternate care costs were compared.

RESULTS

28 patients had a mean age 49 years; average length of stay 120 days. DIAGNOSES: liver disease 43%, HIV/AIDS 25%, malignancy 25% and other 8%. Addiction to drugs or alcohol and mental illness in 82% of patients. Karnofsky performance score mean 40 +/- 16.8. Pain management with continuous opiates in 71%. The majority reunited with family. Compared to alternate care locations, the hospice projected 1.39 million dollars savings for the patients described.

CONCLUSION

The homeless terminally ill have a heavy burden of disease including physical illness, psychiatric conditions and addictions. Shelter-based palliative care can provide effective end-of-life care to terminally ill homeless individuals at potentially substantial cost savings.

The economic burden of lung cancer and the associated costs of treatment failure in the United States

The economic burden of lung cancer was examined with a retrospective case-control cohort study on a database containing inpatient, outpatient and drug claims for employees, dependents and retirees of multiple large US employers with wide geographic distribution. Patients were followed for maximum of 2 years from first cancer diagnosis until death, health benefits dis-enrollment or study end (31 December 2000). Compared with controls (subjects without any cancer), patients with lung cancer (n = 2040) had greater health care service utilization and costs for hospitalization, emergency room visits, outpatient office visits, radiology procedures, laboratory procedures and pharmacy-dispensed drugs (all P < 0.05). Regression-adjusted mean monthly total costs were US dollar 6520 for patients versus US dollar 339 for controls (P < 0.0001), and overall costs across the study period (from diagnosis to death or maximum of 2 years) were US dollar 45,897 for patients and US dollar 2907 for controls (P < 0.0001). The main cost drivers were hospitalization (49.0% of costs) and outpatient office visits (35.2% of costs). Monthly initial treatment phase costs (US dollar 11,496 per patient) were higher than costs during the secondary treatment phase (US dollar 3733) or terminal care phase (US dollar 9399). Failure of initial treatment was associated with markedly increased costs. Compared with patients requiring only initial treatment, patients experiencing treatment failure accrued an additional US dollar 10,370 per month in initial treatment phase costs and US dollar 8779 more per month after starting the secondary and/or terminal care phase. Over the course of the study period, these patients had total costs of US dollar 120,650, compared with US dollar 45,953 for those receiving initial treatment only. Thus, the incremental costs associated with treatment failure were US dollar 19,149 per month and US dollar 74,697 across the study period. Other types of clinical and epidemiological analysis are needed to identify risks for treatment failure. The economic burden of lung cancer on the US health care system is significant and increased prevention, new therapies or adjuvant chemotherapy may reduce both resource use and healthcare costs. New strategies for lung cancer that reduce hospitalizations and/or prevent or delay treatment failure could offset some of the economic burden associated with the disease.

The need for online information on the economic consequences of cancer diagnosis, treatment, and survivorship

The Internet is commonly used to provide treatment information to patients diagnosed with cancer. Notably missing from the existing websites is information on the cost of cancer care in terms of medical costs to the patient and work-related consequences. The purpose of this paper is to describe what is known about the economic cost of cancer and to describe how this information can be structured so that it is of more benefit to patients. This paper first provides an overview of the information available regarding medical expenses and productivity costs associated with cancer survivorship, particularly with respect to cancer and employment. Second, it draws attention to the sparse economic information available online to cancer survivors. Patients can find information on sources of financial assistance, but they cannot estimate from the available information the cost of their care or anticipate the impact that cancer and its treatment may have on their jobs. Finally, a strategy for filling the void in online economic cancer information is described. Substantial opportunity exists to provide economic information to cancer patients and their families. The Internet is a natural forum for gathering and disseminating economic information. A unique advantage of the Internet is its ability to put information immediately in the hands of cancer patients and their families—assisting them to become informed consumers and skilled negotiators.

Endoscopic Ultrasound for Thoracic Malignancy: A Review

Accurate cancer staging is critical in providing the most appropriate therapy for patients with lung cancer. The decision to attempt a curative surgery or avoid an unnecessary surgery is dependent on accurate staging. In the case of non-small-cell lung cancer (NSCLC), the most important parameters for optimal treatment and prognosis are the presence of cancer spread to the lymph nodes within the mediastinum and to distant organs. Endoscopic ultrasound (EUS) has become an important tool for the assessment of mediastinal lymph nodes and in some cases, distant organ metastases, because of its minimally invasive access to these sites through a transesophageal, transgastric, or transduodenal approach. The capability of performing fine needle aspiration (FNA) has greatly improved the accuracy and acceptability of EUS for lung cancer staging. This review will outline the basic principals of EUS-guided lung cancer staging and EUS-FNA techniques and outline the indications and contraindications to EUS staging of thoracic malignancy.

Les composantes du coût des stratégies de prise en charge du cancer du poumon en France

INTRODUCTION

To evaluate the average cost of therapeutic strategies for the management of lung cancer in relation to histological type and diagnostic staging and of the individual components of the management strategy.

METHODS

Samples were taken between 1 September 1998 and 30 June 1999 from centres with sufficient numbers of lung cancer (LC) cases. All events over an 18 Month period were collected from a retrospective analysis of the records. A Markov model was constructed based on decision branches for localised and diffuse small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). Several components of management were identified: first line treatment, second line treatment, observation, terminal care and death.

RESULTS

The average cost of LC was 22,006 Euro (10,631-36,296) for one year and 25,643 Euro (10,631-46,191) for two years. For SCLC the average annual costs were 22,420 Euro for diffuse disease and 27,098 for localised disease. For NSCLC the totals ranged from 19,543 Euro for inoperable stage I and II tumours to 39,424 for operable tumours. The cost for stage IV tumours was 24,383 Euro. The cost components over two Years varied according to the tumour type. The cost of diagnosis ranged from 6-14%, the cost of management and of terminal care from 33-45% of the total. Analyses of sensitivity confirmed that whatever the histological type or diagnostic staging the percentage of patients initially treated actively (that is to say not by palliative care) had the greatest effect on the total cost, greater than the costs of terminal care and of two courses of chemotherapy.

CONCLUSIONS

This model has allowed for the first time the calculation of the contributions of the different therapeutic components to the total cost of the management of lung cancer in France. In the future it will allow analysis of the economic impact of new methods of treatment.

Lung Cancer: A Cost and Outcome Study Based on Physician Practice Patterns

Chemotherapy is now an acceptable treatment for selected patients with non-small-cell lung cancer. With the wide assortment of cytotoxic and supportive-care drugs, there are opportunities for assessing the value of various treatment approaches. This study was undertaken to assess variations in treatment patterns in a large oncology group with emphasis on costs incurred and survival. A total of 1215 patients seen in 1996 by Medical Oncologists (a community-based private practice) were identified as new lung cancer patients by review of billing data. Of these, 858 received chemotherapy and were evaluated for charges. Three hundred were evaluated for charges, hospice care, and survival. Differences in practice patterns for physicians and the causes of those differences were assessed. Differences in survival, charges, and hospice care for those patients who were seen by high-charge and low-charge physicians were measured. Clear differences emerged in practice patterns for these Medical Oncologists. Higher charges were associated with higher average number of chemotherapy cycles given, greater use of second- and third-line chemotherapy and greater use of support drugs, particularly G-CSF and erythropoietin. For stage IV non-small-cell lung cancer, there was no difference in survival or in hospice utilization for the two groups. For all patients combined, there was no significant survival difference. There may be as much as 100% difference in costs incurred for lung cancer chemotherapy based on variations in practice patterns alone without a measurable survival difference. These results suggest approaches for cost-minimization and disease management. These suggestions have been reinforced by recent clinical data and guideline development.

Gefitinib, a novel, orally administered agent for the treatment of cancer

Traditional cytotoxic anticancer therapies do not differentiate between tumour and host cells, and research efforts have been focused on finding new agents that target tumour tissue. Gefitinib ('Iressa', ZD1839) is an orally active epidermal growth factor receptor tyrosine kinase inhibitor that blocks signal pathways implicated in solid tumour growth and metastasis. In phase II trials, gefitinib 250 mg/day demonstrated efficacy in the control of advanced non-small-cell lung cancer (NSCLC) in patients who had undergone prior chemotherapy. Response rates were 18.4 and 11.8%, and disease control rates were 54.4 and 42.2%, at 250 mg/day in two multicentre trials - IDEAL 1 and 2. Gefitinib also caused rapid relief from the symptoms of NSCLC in approximately 40% of patients, while displaying a generally good tolerability profile that most commonly included mild, reversible gastrointestinal and skin adverse events. Gefitinib 250 mg/day has been approved for use in advanced, previously treated NSCLC in several countries including the USA, Japan and Australia. As a monotherapy and combination therapy, it is being investigated for the treatment of several common tumour types in addition to NSCLC. The pharmacokinetics of gefitinib have shown it to be suitable for once daily dosing, with a terminal half-life of approximately 48 h in patients with cancer. Steady-state exposure is achieved after 10 days dosing, and exposure is dose proportional up to 250 mg/day. Gefitinib is cleared principally by the biliary route and in part by metabolism.

Economics of the clinical management of lung cancer in France: an analysis using a Markov model

To evaluate, according to the histologic type and initial stage, the mean cost (MC) of managing patients with lung cancer and the costs of the different management phases. A Markov approach was used to model these costs, based on the management of a representative nation-wide sample of 428 patients with newly diagnosed lung cancer. The 18-month MC ranged from US$ 20 691 (95% CI: 5777–50 380 for diffuse non-small-cell lung cancer (NSCLC) to US$ 31 833 (95% CI: 15 866–64 455) for localised small-cell lung cancer (SCLC); first-line treatment costs ranged from 33.8% of MC for medically inoperable localised NSCLC to 74.6% for diffuse SCLC; second- or third-line treatment costs ranged from 7.8% of MC for surgically treated localised NSCLC to 32% for locally advanced NSCLC; and the cost of palliative care ranged from 9.1% of MC for locally advanced NSCLC to 39.9% for medically inoperable localised NSCLC. The cost of first-line chemotherapy and the percentage of actively treated patients impacted more on MC than did the cost of second- or third-line chemotherapy regimens or the cost of palliative care. In conclusion, this model provides a robust economic analysis of the cost of lung cancer management, and will be useful for assessing the economic consequences of future changes in patient management.

Retrospective cost analysis of gemcitabine in combination with cisplatin in non-small cell lung cancer compared to other combination therapies in Europe

In two recent randomised trials, gemcitabine plus cisplatin (Gem/Cis) was found to be at least as effective as vinorelbine plus cisplatin (Vin/Cis), paclitaxel plus cisplatin (Pac/Cis), paclitaxel plus carboplatin (Pac/Carbo), or docetaxel plus cisplatin (Doc/Cis) in patients with advanced non-small cell lung cancer (NSCLC). In cost-minimisation analyses of these studies from the perspectives of the national health services of five European countries (France, Germany, Italy, Spain, UK), Gem/Cis was associated with lower average treatment-related costs than Vin/Cis, Pac/Cis, and Pac/Carbo, and similar or lower costs than Doc/Cis. The incremental cost savings per patient of Gem/Cis compared to Vin/Cis ranged from 827 Euro to 2055 Euro per patient and from 1616 Euro to 5342 Euro compared to the paclitaxel-containing regimens. Overall, results were generally similar between countries, and were robust to univariate sensitivity analyses. Although differences in healthcare systems mean that the results may not be generalisable to all countries/settings, these results provide an economic rationale for the use of Gem/Cis as a first-line treatment option in Europe for patients with NSCLC.

Strategies in lung cancer detection. Achieving early identification in patients at high risk

Screening can be crucial for timely identification of lung cancer and thus for early treatment and a favorable prognosis. This conclusion is true particularly for persons at high risk for lung cancer, including those exposed to asbestos or silicon dust. In this article, Drs Bechtel and Petty discuss the types of screening procedures available, their cost, and the approaches and timing that are most beneficial to the public as a whole.

Non-small cell lung cancer staging techniques and endoscopic ultrasound: tissue is still the issue

Non-small cell lung cancer (NSCLC) in the United States will continue to be a major public health issue, particularly as our elderly population grows. As surgery offers the best hope of cure for NSCLC, staging of NSCLC is critical because it directly impacts on the management of lung cancer. Cost, quality of life, safety, and accuracy of various staging methods all influence the clinical outcome. Staging of NSCLC is evolving due to the emergence of new and improved technologies. The objective of this article is to review the current methods used in staging of NSCLC. Currently, positron emission tomography and endoscopic ultrasound (EUS) show promise in identifying patients that may benefit from surgery. Histologic confirmation via EUS-guided fine-needle aspiration, however, may still be necessary to accurately stage the mediastinum.

Appraising the economic efficiency of cancer treatment: an exploratory analysis of lung cancer

This paper tests whether the measured cost-effectiveness of treating different subgroups of an incident population of lung cancer patients differs significantly and, by implication, whether the provision of care to these patients is tolerably efficient in economic terms. Data from administrative records and Registry follow-up on 544 non-small cell lung cancer patients diagnosed at a single NCI-designated Comprehensive Cancer Center are used to conduct the empirical analysis. The main results show statistically significant differences in cumulative costs and patient outcomes across subgroups differing by disease stage and treatment modality. These findings imply that the delivery of lung cancer care is inefficient. Substantive and methodological implications are discussed.

Description and predictors of direct and indirect costs of pain reported by cancer patients

The purpose of this study was to describe direct and indirect costs associated with pain in cancer patients and to examine potential predictors of these costs. The study surveyed cancer outpatients about direct costs resulting from pain-related hospitalizations, emergency department visits, physician office visits, and use of analgesic medications and indirect costs related to money spent on pain-related transportation, complementary methods to improve pain management, educational materials, over-the counter medication, domestic support, and childcare. Furthermore, the study examined age, marital status, race, income level, pain severity, pain interference, and presence of breakthrough pain as predictors of direct and indirect costs. Three hundred and seventy-three cancer outpatients were sampled. One hundred and forty-four cancer patients (39%) reported experiencing cancer-related pain and completed the study questionnaires. Seventy-six percent (76%) of the patients had experienced at least one pain-related cost, resulting in an average monthly direct cost of US$ 891/month per patient. Sixty-nine percent (69%) of patients had experienced some type of direct medical cost due to pain, resulting in an average total direct pain-related cost of US$ 825/month per patient. Fifty-seven percent (57%) of patients reported incurring at least one indirect pain-related expense for an average indirect cost of US$ 61/month per patient. Higher pain intensity, greater pain interference, and presence of breakthrough pain predicted higher direct and indirect medical expenses. Younger age and lower income level also predicted higher direct medical expenses.

Direct treatment costs for patients with lung cancer from first recurrence to death in france

OBJECTIVE

To determine the direct treatment cost of lung cancer management from progression to death from the viewpoint of the hospital.

METHODS

A retrospective descriptive study was performed. Data from 100 patients who died of lung cancer and who had received treatment from four different types of hospital were used; the hospitals were public hospitals (teaching and non-teaching), private not-for-profit cancer centres, and private hospitals. Resource utilisation/cost data collected included the cost of diagnosis of the recurrence, the cost of hospitalisations or day care treatments and ambulatory surgery. All resources were valued in 2001 euros.

RESULTS

In France, the average cost per patient was euro12 518 for the whole group (78% with non-small cell lung cancer [NSCLC], and 22% with small cell lung cancer [SCLC]), euro13 969 for patients with NSCLC and euro7369 for patients with SCLC. The higher cost of treatment in patients with NSCLC is explained by longer survival and duration of chemotherapy. In patients with NSCLC, 51% of the total cost corresponded to terminal care, with up to seven lines of chemotherapy. In patients with SCLC, the costs of diagnosis and terminal care each represented 41% of the total cost.

CONCLUSIONS

The cost of treatment of recurrence of lung carcinoma is high, and is related to the number of lines of chemotherapy and the use of radiotherapy and surgery.

Burden of illness associated with metastatic melanoma: an audit of 100 consecutive referral center cases

BACKGROUND

Although long-term survival in patients with metastatic melanoma (MM) is infrequent, response to a variety of cytotoxic and immunotherapies occurs and survival varies based on the site of metastases. Because different patterns of care of MM are likely to vary substantially in their intensity and resource use, the authors audited care at a regional referral center.

METHODS

The records of 100 consecutive new patients with MM who presented at the University of Pittsburgh Cancer Institute (UPCI) after January 1997 were audited. Demographics, disease sites, and treatment prior to presentation at UPCI as well as the diagnostic and therapeutic methods undertaken at UPCI were tracked monthly with regard to inpatient and outpatient activity.

RESULTS

The median age of the patient cohort was 51 years was a median 2.2 years after the time of initial diagnosis. Eighty-two percent of the patients had died and only 8% had been lost to long-term follow-up. Eighty-seven percent of patients had been referred to UPCI and 28% had received some treatment prior to presenting at UPCI. The median survival was 9.0 months. The lung was the most common symptomatic site and 38% of patients developed central nervous system (CNS) metastases. Eighty-four percent of patients initially were treated on a research protocol 30% of whom were part of a Phase III study. Twenty-nine percent of the patients were never hospitalized. The most common reason for hospitalization was elective treatment with high-dose interleukin-2. Lifetime hospital days averaged only 7.3 days. Therapeutic actions (if ever given) by category type were surgery in 23% of patients, radiation therapy in 44%, immunotherapy in 75%, and chemotherapy in 51%. Using assigned values for the identified resources used, the approximate cost per patient averaged $59,400.

CONCLUSIONS

The current audit of MM patients demonstrated that lung and CNS metastases dominate a broad variety of complications, that clinical trial participation was the norm, that hospitalizations occurred relatively infrequently, and that the direct health care costs of current treatment patterns are among the highest for all malignancies. Medical auditing of contemporary American cancer care provides meaningful insights into its patterns of care.

Duration of hospitalization as a measure of cost on Children's Cancer Group acute lymphoblastic leukemia studies

PURPOSE

We used duration of hospitalization as a surrogate for cost and event-free survival as a measure of effectiveness to estimate the cost-effectiveness ratios of various treatment regimens on Children's Cancer Group trials for acute lymphoblastic leukemia.

PATIENTS AND METHODS

The analyses included 4,986 children (2 to 21 years of age) with newly diagnosed acute lymphoblastic leukemia enrolled onto risk-adjusted protocols between 1988 and 1995. Analyses were based on a model of 100 patients. The marginal cost-effectiveness ratio (hospital days per additional patient surviving event-free) was the difference in total duration of hospitalization divided by the difference in number of event-free survivors at 5 years for two regimens. Relapse-adjusted marginal cost of frontline therapy was the difference in total duration of hospitalization for frontline therapy plus relapse therapy divided by the difference in number of event-free survivors at 5 years on the frontline therapy for two regimens.

RESULTS

One or two delayed intensification (DI) phases, augmented therapy, and dexamethasone all improved outcome. Marginal cost-effectiveness of these regimens compared with the control regimens was 133 days per patient for DI, 117 days per patient for double DI, and 41 days per patient for augmented therapy. Dexamethasone resulted in 17 fewer days per patient. Relapse-adjusted marginal costs were 68 days per patient for DI and 52 days for double DI. Augmented therapy and dexamethasone-based therapy resulted in 16 and 82 fewer hospital days, respectively. The estimated cost-effectiveness for treating any first relapse was 250 days per patient.

CONCLUSION

DI, double DI, augmented therapy, and dexamethasone-based therapy are cost-effective strategies compared with current treatment of first relapse.
