Evaluation of trends in the cost of initial cancer treatment

Update on the treatment of non-small-cell lung cancer: focus on the cost-effectiveness of new agents

Background

The incidence of lung cancer and the cost of drug treatment have increased dramatically in the last decade. This article examines the costs of new target agents, such as tyrosine kinase inhibitors (TKIs) and anti-angiogenic drugs.

Methods

This study uses PubMed research to focus on the topics of lung cancer, economics, and new targeted therapies.

Results

The published papers only addressed TKIs and anti-angiogenic antibodies. For gefitinib, the results favored a clinical-based selection, despite the low number of studies. Erlotinib was studied in second line and as a maintenance treatment (with the studies reaching opposite conclusions in terms of cost-effectiveness). Economic analyses were not in favor of bevacizumab, but the studies on this topic were very heterogeneous.

Conclusion

The economic impact of a drug depends on the health care system organization. Future clinical trials must include economic analyses, particularly with TKIs in the first line.

State-level cancer treatment costs: how much and who pays?

BACKGROUND

Cancer treatment accounts for approximately 5% of national health expenditures. However, no state-level estimates of cancer treatment costs have been published.

METHODS

In analyses of data from the Medical Expenditure Panel Survey, the National Nursing Home Survey, the U.S. Census Bureau, the Current Population Survey, and the Centers for Medicare & Medicaid Services, this study used regression modeling to estimate annual state-level cancer care costs during 2004 to 2008 for 4 categories of payers: all payers, Medicare, Medicaid, and private insurance.

RESULTS

State-level cancer care costs ranged from $227 million to $13.6 billion (median = $2.0 billion) in 2010 dollars. Medicare paid between 25.1% and 36.1% of these costs (median = 32.5%); private insurance paid between 36.0% and 49.6% (median = 43.3%); and Medicaid paid between 2.0% and 8.8% (median = 4.8%). Cancer treatment accounted for 3.8% to 8.7% of all state-level medical expenditures (median = 7.0%), 8.5% to 15.0% of state-level Medicare expenditures (median = 10.6%), 1.0% to 4.9% of state-level Medicaid expenditures (median = 2.2%), and 5.5% to 10.9% of state-level private insurance expenditures (median = 8.7%).

CONCLUSIONS

The costs of cancer treatment were substantial in all states and accounted for a sizable fraction of medical expenditures for all payers. The high cost of cancer treatment underscores the importance of preventing and controlling cancer as one approach to manage state-level medical costs.

Hospital visits among women with skeletal-related events secondary to breast cancer and bone metastases: a nationwide population-based cohort study in Denmark

Objective

Skeletal-related events (SREs) among women with breast cancer may be associated with considerable use of health-care resources. We characterized inpatient and outpatient hospital visits in a national population-based cohort of Danish women with SREs secondary to breast cancer and bone metastases.

Methods

We identified first-time breast cancer patients with bone metastases from 2003 through 2009 who had a subsequent SRE (defined as pathologic fracture, spinal cord compression, radiation therapy, or surgery to bone). Hospital visits included the number of inpatient hospitalizations, length of stay, number of hospital outpatient clinic visits, and emergency room visits. The number of hospital visits was assessed for a pre-SRE period (90 days prior to the diagnostic period), a diagnostic period (14 days prior to the SRE), and a post-SRE period (90 days after the SRE). Patients who experienced more than one SRE during the 90-day post-SRE period were defined as having multiple SREs and were followed until 90 days after the last SRE.

Results

We identified 569 women with SREs secondary to breast cancer with bone metastases. The majority of women had multiple SREs (73.1%). A total of 20.9% and 33.4% of women with single and multiple SREs died in the post-SRE period, respectively. SREs were associated with a large number of hospital visits in the diagnostic period, irrespective of the number and type of SREs. Women with multiple SREs generally had a higher number of visits compared to those with a single SRE in the post-SRE period, eg, median length of hospitalization was 5 days (interquartile range 0–15) for women with a single SRE and 13 days (interquartile range 4–30) for women with multiple SREs.

Conclusion

SREs secondary to breast cancer and bone metastases were associated with substantial use of hospital resources.

Uptake and outcomes of intensity-modulated radiation therapy for uterine cancer

OBJECTIVE

While intensity-modulated radiation therapy (IMRT) allows more precise radiation planning, the technology is substantially more costly than conformal radiation and, to date, the benefits of IMRT for uterine cancer are not well defined. We examined the use of IMRT and its effect on late toxicity for uterine cancer.

METHODS

Women with uterine cancer treated from 2001 to 2007 and registered in the SEER-Medicare database were examined. We investigated the extent and predictors of IMRT administration. The incidence of acute and late-radiation toxicities was compared for IMRT and conformal radiation.

RESULTS

We identified a total of 3555 patients including 328 (9.2%) who received IMRT. Use of IMRT increased rapidly and reached 23.2% by 2007. In a multivariable model, residence in the western U.S. and receipt of chemotherapy were associated with receipt of IMRT. Women who received IMRT had a higher rate of bowel obstruction (rate ratio=1.41; 95% CI, 1.03-1.93), but other late gastrointestinal and genitourinary toxicities as well as hip fracture rates were similar between the cohorts. After accounting for other characteristics, the cost of IMRT was $14,706 (95% CI, $12,073 to $17,339) greater than conformal radiation.

CONCLUSION

The use of IMRT for uterine cancer is increasing rapidly. IMRT was not associated with a reduction in radiation toxicity, but was more costly.

An economic model to value companion diagnostics in non-small-cell lung cancer

Aim: An economic model was used to evaluate the potential economic impact and cost–effectiveness of companion diagnostic testing for patients with non-small-cell lung cancer (NSCLC). Materials & methods: A decision analysis model examined alternative patient management strategies for patients with advanced NSCLC who were not amenable to surgical treatment. A review of the literature provided the variables used to develop a timely base case and sensitivity analysis. A potential future scenario was also modeled. The model includes three options: conventional treatment (CT), new treatment (NT) and companion diagnostic (CD) strategy. Results: In the base case analysis based upon current data, the cost per life-year saved for CT, NT option and CD was US$43,367, US$47,394 and US$47,779, respectively. The cost per life-year saved for CT, NT option and CD in a potential future scenario with more expensive, effective targeted therapy was US$47,748, US$69,255 and US$66,369, respectively. Conclusion: In the future scenario, CDs have an incremental cost–effectiveness of US$56,829 per life-year saved when compared with NT as a first-line treatment. This is one demonstration of how CDs may be a cost-effective option for the treatment of patients with advanced NSCLC when the NT is extremely expensive but the outcome is significantly improved.

Incremental costs of prostate cancer trials: Are clinical trials really a burden on a public payer system?

INTRODUCTION

Clinical trials are a critical component of improving cancer prevention and treatment strategies. However, the perception that patients enrolled in trials consume more resources than those receiving the standard-of-care (SOC) has contributed to an increasingly research-averse environment. Current economic data pertaining to the per-patient costs of prostate cancer trials relative to SOC treatment are limited.

METHODS

A retrospective observational cohort study was conducted to compare costs incurred by 59 prostate cancer patients participating in a mix of industry and non-industry sponsored clinical trials with costs incurred by an equal number of eligible non-participants who received SOC over a year. Resource utilization was tracked and quantified to standardized price templates.

RESULTS

No difference in overall resource utilization was seen between trial and SOC patients (two-tailed t-test, n = 118, p = 0.99). Variability in the types of resources used by each group indicated that, while trial patients may take up significantly more clinic time (p = 0.001) and undergo more tests and procedures (p = 0.001), SOC patients are more likely to receive other costly interventions, such as radiation therapy (p < 0.001). Other variables (e.g., pathology, diagnostic imaging, prescribed therapies) were statistically indistinguishable between groups.

CONCLUSION

This study revealed differences in the cost distribution of patients enrolled in clinical trials versus those receiving SOC, which could be used to improve resource allocation. The lack of evidence for a difference in overall cost provides an argument for payers to more fully support clinical research without fear of adverse financial consequences. Further analysis is required.

The cost of breast cancer screening in the Medicare population

BACKGROUND

Little is known about the cost to Medicare of breast cancer screening or whether regional-level screening expenditures are associated with cancer stage at diagnosis or treatment costs, particularly because newer breast cancer screening technologies, like digital mammography and computer-aided detection (CAD), have diffused into the care of older women.

METHODS

Using the linked Surveillance, Epidemiology, and End Results-Medicare database, we identified 137 274 women ages 66 to 100 years who had not had breast cancer and assessed the cost to fee-for-service Medicare of breast cancer screening and workup during 2006 to 2007. For women who developed cancer, we calculated initial treatment cost. We then assessed screening-related cost at the Hospital Referral Region (HRR) level and evaluated the association between regional expenditures and workup test utilization, cancer incidence, and treatment costs.

RESULTS

In the United States, the annual costs to fee-for-service Medicare for breast cancer screening-related procedures (comprising screening plus workup) and treatment expenditures were $1.08 billion and $1.36 billion, respectively. For women 75 years or older, annual screening-related expenditures exceeded $410 million. Age-standardized screening-related cost per beneficiary varied more than 2-fold across regions (from $42 to $107 per beneficiary); digital screening mammography and CAD accounted for 65% of the difference in screening-related cost between HRRs in the highest and lowest quartiles of cost. Women residing in HRRs with high screening costs were more likely to be diagnosed as having early-stage cancer (incidence rate ratio, 1.78 [95% CI, 1.40-2.26]). There was no significant difference in the cost of initial cancer treatment per beneficiary between the highest and lowest screening cost HRRs ($151 vs $115; P = .20).

CONCLUSIONS

The cost to Medicare of breast cancer screening exceeds $1 billion annually in the fee-for-service program. Regional variation is substantial and driven by the use of newer and more expensive technologies; it is unclear whether higher screening expenditures are achieving better breast cancer outcomes.

Human endogenous retroviruses and cancer prevention: evidence and prospects

Background

Cancer is a significant and growing problem worldwide. While this increase may, in part, be attributed to increasing longevity, improved case notifications and risk-enhancing lifestyle (such as smoking, diet and obesity), hygiene-related factors resulting in immuno-regulatory failure may also play a major role and call for a revision of vaccination strategies to protect against a range of cancers in addition to infections.

Discussion

Human endogenous retroviruses (HERVs) are a significant component of a wider family of retroelements that constitutes part of the human genome. They were originated by the integration of exogenous retroviruses into the human genome millions of years ago. HERVs are estimated to comprise about 8% of human DNA and are ubiquitous in somatic and germinal tissues.

Physiologic and pathologic processes are influenced by some biologically active HERV families. HERV antigens are only expressed at low levels by the host, but in circumstances of inappropriate control their genes may initiate or maintain pathological processes. Although the precise mechanism leading to abnormal HERVs gene expression has yet to be clearly elucidated, environmental factors seem to be involved by influencing the human immune system.

HERV-K expression has been detected in different types of tumors.

Among the various human endogenous retroviral families, the K series was the latest acquired by the human species. Probably because of its relatively recent origin, the HERV-K is the most complete and biologically active family.

The abnormal expression of HERV-K seemingly triggers pathological processes leading to melanoma onset, but also contributes to the morphological and functional cellular modifications implicated in melanoma maintenance and progression.

The HERV-K-MEL antigen is encoded by a pseudo-gene incorporated in the HERV-K env-gene. HERV-K-MEL is significantly expressed in the majority of dysplastic and normal naevi, as well as other tumors like sarcoma, lymphoma, bladder and breast cancer. An amino acid sequence similar to HERV-K-MEL, recognized to cause a significant protective effect against melanoma, is shared by the antigenic determinants expressed by some vaccines such as BCG, vaccinia virus and the yellow fever virus.

HERV-K are also reactivated in the majority of human breast cancers. Monoclonal and single-chain antibodies against the HERV-K Env protein recently proved capable of blocking the proliferation of human breast cancer cells in vitro, inhibiting tumor growth in mice bearing xenograft tumors.

Summary

A recent epidemiological study provided provisional evidence of how melanoma risk could possibly be reduced if the yellow fever virus vaccine (YFV) were received at least 10 years before, possibly preventing tumor initiation rather than culling melanoma cells already compromised. Further research is recommended to confirm the temporal pattern of this protection and eliminate/attenuate the potential role of relevant confounders as socio-economic status and other vaccinations.

It appears also appropriate to examine the potential protective effect of YFV against other malignancies expressing high levels of HERV-K antigens, namely breast cancer, sarcoma, lymphoma and bladder cancer.

Tumor immune-therapy, as described for the monoclonal antibodies against breast cancer, is indeed considered more complex and less advantageous than immune-prevention. Cellular immunity possibly triggered by vaccines as for YFV might also be involved in anti-cancer response, in addition to humoral immunity.

Cancer Treatment for Dual Eligibles: What Are the Costs and Who Pays?

This study quantifies treatment costs for melanoma and breast, cervical, colorectal, lung, and prostate cancer among patients with dual Medicare and Medicaid eligibility. The analyses use merged Medicare and Medicaid Analytic eXtract enrollment and claims data for dually eligible beneficiaries age>18 in Georgia, Illinois, Louisiana, and Maine in 2003 (n=892,001). We applied ordinary least squares regression analysis to estimate annual expenditures attributable to each cancer after controlling for beneficiaries' age, race/ethnicity, sex, and comorbid conditions, and state fixed effects. Cancers and comorbid conditions were identified on the basis of diagnosis codes on insurance claims. The most prevalent cancers were prostate (38.4 per 1,000 men) and breast (30.7 per 1,000 women). Dual eligibles with the study cancers had higher rates of other chronic conditions such as hypertension and arthritis than other beneficiaries. Total Medicare and Medicaid expenditures for dual eligibles with the study cancers ranged from $30,328 for those with lung cancer to $17,011 for those with breast cancer, compared with $10,664 for beneficiaries without the cancers. However, only 9% to 30% of medical expenditures for dual eligibles with the study cancers were attributable to the cancer itself. In 2003, combined Medicare/Medicaid spending for dual eligibles attributable to the six cancers in the four study states exceeded $256 million ($314 million in 2012 dollars). Dual eligibles with these cancers also had high rates of other medical conditions. These comorbidities should be recognized, both in documenting cancer treatment costs and in developing programs and policies that promote timely cancer diagnosis and treatment.

Understanding the costs of cancer care before and after diagnosis for the 21 most common cancers in Ontario: a population-based descriptive study

BACKGROUND

The first year after cancer diagnosis is a period of intensive treatment and high cost. We sought to estimate costs for the 21 most common cancers in Ontario in the 3-month period before and the first year after diagnosis.

METHODS

We used the Ontario Cancer Registry to select patients who received diagnoses between 1997 and 2007 at 19 years of age or older, with valid International Classification of Diseases for Oncology (ICD-O) and histology codes, who survived 30 days or longer after diagnosis and had no second cancer within 90 days of the initial cancer (n = 402 399). We used linked administrative data to calculate mean costs for each cancer during the pre- and postdiagnosis periods for patients who died within 1 year after diagnosis and patients who survived beyond 1 year after diagnosis.

RESULTS

Mean prediagnosis costs were $2060 (95% confidence interval [CI] $2023-$2098) for all patients with cancer. Costs ranged from $890 (95% CI $795-$985) for melanoma to $4128 (95% CI $3591-$4664) for liver cancer among patients who survived beyond 1 year after diagnosis, and ranged from $2188 (95% CI $2040-$2336) for esophageal cancer to $5142 (95% CI $4664-$5620) for multiple myeloma among patients who died within 1 year. The mean postdiagnosis cost for our cohort was $25 914 (95% CI $25 782-$26 046). Mean costs were lowest for melanoma ($8611 [95% CI $8221-$9001]) and highest for esophageal cancer ($50 620 [95% CI $47 677-$53 562] among patients who survived beyond 1 year after diagnosis, and ranged from $27 560 (95% CI $25 747-$29 373) for liver cancer to $81 655 (95% CI $58 361-$104 949) for testicular cancer among patients who died within 1 year.

INTERPRETATION

Our research provides cancer-related cost estimates for the pre- and postdiagnosis phases and offers insight into the economic burden incurred by the Ontario health care system. These estimates can help inform policy-makers' decisions regarding resource allocation for cancer prevention and control, and can serve as important input for economic evaluations.

Medical oncologists' perceptions of financial incentives in cancer care

PURPOSE

The cost of cancer care continues to increase at an unprecedented rate. Concerns have been raised about financial incentives associated with the chemotherapy concession in oncology practices and their impact on treatment recommendations.

METHODS

The objective of this study was to measure the physician-reported effects of prescribing chemotherapy or growth factors or making referrals to other cancer specialists, hospice, or hospital admissions on medical oncologists' income. US medical oncologists involved in the care of a population-based cohort of patients with lung or colorectal cancer from the Cancer Care Outcomes Research and Surveillance (CanCORS) study were surveyed regarding their perceptions of the impact of prescribing practices or referrals on their income.

RESULTS

Although most oncologists reported that their incomes would be unaffected, compared with salaried oncologists, physicians in fee-for-service practice, and those paid a salary with productivity incentives were more likely to report that their income would increase from administering chemotherapy (odds ratios [ORs], 7.05 and 7.52, respectively; both P < .001) or administering growth factors (ORs, 5.60 and 6.03, respectively; both P < .001).

CONCLUSION

A substantial proportion of oncologists who are not paid a fixed salary report that their incomes increase when they administer chemotherapy and growth factors. Further research is needed to understand the impact of these financial incentives on both the quality and cost of care.

Out-of-pocket health care expenditure burden for Medicare beneficiaries with cancer

BACKGROUND

There is increasing concern regarding the financial burden of care on cancer patients and their families. Medicare beneficiaries often have extensive comorbidities and limited financial resources, and may face substantial cost sharing even with supplemental coverage. In the current study, the authors examined out-of-pocket (OOP) spending and burden relative to income for Medicare beneficiaries with cancer.

METHODS

This retrospective, observational study pooled data for 1997 through 2007 from the Medicare Current Beneficiary Survey linked to Medicare claims. Medicare beneficiaries with newly diagnosed cancer were selected using claims-based diagnoses. Generalized linear models were used to estimate OOP spending. Logistic regression models identified factors associated with a high OOP burden, defined as spending > 20% of one's income during the cancer diagnosis and subsequent year.

RESULTS

The cohort included 1868 beneficiaries with and 10,047 without cancer. Compared with the noncancer cohort, cancer patients were older, had more comorbidities, and were more likely to lack supplemental coverage. The mean OOP spending for cancer patients was $4727. Cancer patients faced an adjusted $976 (P < .01) incremental OOP spending. Greater than one-quarter (28%) of beneficiaries with cancer experienced a high OOP burden compared with 16% of beneficiaries without cancer (P < .001). Supplemental insurance and higher income were found to be protective against a high OOP burden, whereas assets, comorbidity, and receipt of cancer-directed radiation and antineoplastic therapy were associated with a higher OOP burden.

CONCLUSIONS

Medicare beneficiaries with cancer face a higher OOP burden than their counterparts without cancer; some of the higher burden was explained by the higher comorbidity burden and lack of supplemental insurance noted among these patients. Financial pressures may discourage some elderly patients from pursuing treatment.

Can Centralization of Cancer Surgery Improve Social Welfare?

The empirical association between high hospital procedure volume and lower mortality rates has led to recommendations for the centralization of complex surgical procedures. Yet redirecting patients to a select number of high-volume hospitals creates potential negative consequences for market competition. We use patient-level data to estimate the association between hospital procedure volume and patient mortality and costs. We also estimate the association between hospital market concentration and mortality, cost, and prices. We use our estimates to simulate the change in social welfare resulting from redirecting patients at low-volume hospitals to high-volume facilities. We find that a higher procedure volume leads to significant reductions in mortality for patients undergoing surgery for pancreatic cancer, but not colon cancer. Procedure volume also influences costs for both surgeries, but in a nonlinear fashion. Increased market concentration is associated with higher costs and prices for colon cancer, but not pancreatic cancer patients. Simulations indicated that centralizing pancreatic cancer surgery is unambiguously welfare enhancing. In contrast, there is less evidence to suggest that centralizing colon cancer surgery would be welfare improving.

Comparative effectiveness research in oncology methodology: observational data

The goal of comparative effectiveness research is to inform clinical decisions between alternate treatment strategies using data that reflect real patient populations and real-world clinical scenarios for the purpose of improving patient outcomes. Observational studies using population-based registry data are increasingly relied on to fill the information gaps created by lack of evidence from randomized controlled trials. Administrative data sets have many advantages, including large sample sizes, long-term follow-up, and inclusion of data on physician and systems characteristics as well as cost. In this review, we describe the characteristics of many of the commonly used population-based data sets and discuss the elements included within these data sets. An overview of common research themes that rely on population-based data and illustrative examples are presented. Finally, an overview of the analytic techniques commonly employed by health services researchers to limit the effects of selection bias and confounding is discussed. The analysis of well-designed studies of comparative effectiveness is complex. However, careful framing, appropriate study design, and application of sophisticated analytic techniques can improve the accuracy of nonrandomized studies. There are multiple areas where the unique characteristics of observational studies can inform medical decision making and health policy, and it is critical to appreciate the opportunities, strengths, and limitations of observational research.

Use of imaging in surveillance of women with early stage breast cancer

BACKGROUND

There is no evidence of benefit in terms of survival or quality of life for intensive surveillance of women with early breast cancer (BC) and current guidelines reflect this. We have examined whether Victorian women, nearly 4 years from a diagnosis of localized BC, were being managed according to these guidelines.

METHODS

Participants are women in the BUPA Health Foundation Health and Wellbeing after Breast Cancer prospective cohort study. All participants completed an enrolment questionnaire within 12 months of diagnosis and then completed follow-up questionnaires every 12 months thereafter. In the third follow-up questionnaire, completed nearly 4 years from the time of diagnosis, women were asked about imaging tests they had in the previous 12 months.

RESULTS

The analysis was completed on 673 women who were stage 1 at the time of diagnosis and had not reported evidence of recurrence or a new BC since diagnosis. Of the 673, 603 (89.5%) reported having had a mammogram in the previous 12 months and 319 (52.9% of those having a mammogram) reported a breast ultrasound. Seventy-one per cent of women reported no other imaging investigations in the previous 12 months.

CONCLUSIONS

Our study shows that, nearly 4 years from diagnosis, Australian practitioners are generally adhering to guidelines about imaging surveillance of BC survivors. Practitioners could use the guidelines for the education of BC survivors about appropriate health surveillance.

State-level projections of cancer-related medical care costs: 2010 to 2020

BACKGROUND

As the population ages, the financial amount spent on cancer care is expected to increase substantially. In this study, we projected cancer-related medical costs by state from 2010 through 2020.

METHODS

We used pooled Medical Expenditure Panel Survey data for 2004 to 2008 and US Census Bureau population projections to produce state-level estimates of the number of people treated for cancer and the average cost of their treatment, from a health system perspective, by age group (18-44, 45-64, >65 years) and sex. In the base model, we assumed that the percentage of people in each of the 6 age-by-sex categories who had been treated for cancer would remain constant and that the inflation-adjusted average cancer treatment cost per person would increase at the same rate as Congressional Budget Office projections of overall medical spending.

RESULTS

We projected that state-level cancer-related medical costs would increase by 34% to 115% (median = 72%) and that state-level costs in 2020 would range from $347 million to $28.3 billion in 2010 dollars (median = $3.7 billion).

CONCLUSIONS

The number of people treated for cancer and the costs of their cancer-related medical care are projected to increase substantially for each state. Effective prevention and early detection strategies are needed to limit the growing burden of cancer.

Trends in rates and attributable costs of conditions among female VA patients, 2000 and 2008

RESEARCH OBJECTIVE

We examined rates of specific health conditions among female veteran patients and how the share of health care costs attributable to these conditions changed in the Veterans Affairs system between 2000 and 2008.

METHODS

Veterans' Administration (VA)-provided and VA-sponsored inpatient, outpatient, and pharmacy utilization and cost files were analyzed for women veterans receiving care in 2000 and 2008. We estimated rates of 42 common health conditions and per-patient condition costs from a regression model and calculated the total population costs attributable to each condition and changes by year.

RESULTS

The number of female VA patients increased from 156,305 in 2000 to 266,978 in 2008; 88% were under 65 years of age. The rate of women treated for specific conditions increased substantially for many gender-specific and psychiatric conditions: For example, pregnancy increased 133%, diagnosed posttraumatic stress disorder increased 106%, and diagnosed depression increased 41%. Mean costs of care increased from $4,962 per woman in 2000 to $6,570 per woman in 2008. Psychiatric conditions accounted for more than one quarter of population health care costs in 2008. Gender-specific conditions and musculoskeletal diseases accounted for a rising share of population costs and rose to 8.2% and 8.7% of population costs in 2008, respectively.

CONCLUSION

Gender-specific, cancer, musculoskeletal, and mental health and substance use disorders accounted for a greater share of overall costs during the study period and were primarily driven by higher rates of diagnosed conditions and, for several conditions, higher treatment costs.

Cost of care for colorectal cancer in Ireland: a health care payer perspective

OBJECTIVE

Management options for colorectal cancer have expanded in recent years. We estimated average lifetime cost of care for colorectal cancer in Ireland in 2008, from the health care payer perspective.

METHOD

A decision tree model was developed in Microsoft EXCEL. Site and stage-specific treatment pathways were constructed from guidelines and validated by expert clinical opinion. Health care resource use associated with diagnosis, treatment and follow-up were obtained from the National Cancer Registry Ireland (n=1,498 cancers diagnosed during 2004-2005) and three local hospital databases (n=155, 142 and 46 cases diagnosed in 2007). Unit costs for hospitalisation, procedures, laboratory tests and radiotherapy were derived from DRG costs, hospital finance departments, clinical opinion and literature review. Chemotherapy costs were estimated from local hospital protocols, pharmacy departments and clinical opinion. Uncertainty was explored using one-way and probabilistic sensitivity analysis.

RESULTS

In 2008, the average (stage weighted) lifetime cost of managing a case of colorectal cancer was €39,607. Average costs were 16% higher for rectal (€43,502) than colon cancer (€37,417). Stage I disease was the least costly (€23,688) and stage III most costly (€48,835). Diagnostic work-up and follow-up investigations accounted for 4 and 5% of total costs, respectively. Cost estimates were most sensitive to recurrence rates and prescribing of biological agents.

CONCLUSION

This study demonstrates the value of using existing data from national and local databases in contributing to estimating the cost of managing cancer. The findings illustrate the impact of biological agents on costs of cancer care and the potential of strategies promoting earlier diagnosis to reduce health care resource utilisation and care costs.

The Medical Expenditure Panel Survey (MEPS) experiences with cancer survivorship supplement

INTRODUCTION

The prevalence of cancer survivorship in the USA is expected to increase in the future because the US population is increasing in size and is aging and because survival following diagnosis is improving for many types of cancer. Medical care costs associated with cancer are also projected to increase dramatically. However, currently available data for estimating medical care costs and other important aspects of the burden of cancer, including time spent receiving medical care, productivity loss due to morbidity for patients and their families, and financial hardship, are limited, particularly in the population under the age of 65.

METHODS

We describe selected publicly available data sources for estimating the burden of cancer in the USA and a new collaborative effort to improve the quality of these data: the nationally representative Medical Expenditure Panel Survey (MEPS) Experiences with Cancer Survivorship Supplement.

CONCLUSIONS

Data from this effort can be used to address key gaps in cancer survivorship research related to medical care costs, employment patterns, financial hardship, and other aspects of the burden of illness for cancer survivors and their families.

IMPLICATIONS FOR CANCER SURVIVORS

Research using the MEPS Experiences with Cancer Survivorship Supplement can inform efforts by health care policy makers, healthcare systems, providers, and employers to improve the cancer survivorship experience in the USA.

Breast Cancer 2012 - New Aspects

Treatment options as well as the characteristics for therapeutic decisions in patients with primary and advanced breast cancer are increasing in number and variety. New targeted therapies in combination with established chemotherapy schemes are broadening the spectrum, however potentially promising combinations do not always achieve a better result. New data from the field of pharmacogenomics point to prognostic and predictive factors that take not only the properties of the tumour but also inherited genetic properties of the patient into consideration. Current therapeutic decision-making is thus based on a combination of classical clinical and modern molecular biomarkers. Also health-economic aspects are more frequently being taken into consideration so that health-economic considerations may also play a part. This review is based on information from the recent annual congresses. The latest of these are the 34th San Antonio Breast Cancer Symposium 2011 and the ASCO Annual Meeting 2012. Among their highlights are the clinically significant results from the CLEOPATRA, BOLERO-2, EMILIA and SWOG S0226 trials on the therapy for metastatic breast cancer as well as further state-of-the-art data on the adjuvant use of bisphosphonates within the framework of the ABCSG-12, ZO-FAST, NSABP-B34 and GAIN trials.

Fracture risk in women with breast cancer: a population-based study

A positive association has been reported between greater bone density and higher breast cancer risk, suggesting that these women could be at reduced risk of fracture. To estimate fracture risk among unselected community women with breast cancer and to systematically assess associations with various risk factors including breast cancer treatments, we conducted a population-based historical cohort study of 608 Olmsted County, MN, USA, women with invasive breast cancer first diagnosed in 1990 to 1999 (mean age 61.6 ± 14.8 years), who were followed for 5776 person-years. Altogether, 568 fractures were observed in 270 women (98 per 1000 person-years). Overall fracture risk was elevated 1.8-fold, but the absolute increase in risk was only 9%, and 56% of the women did not experience a fracture during follow-up. Excluding pathologic fractures (15%) and those found incidentally (24%), to allow for ascertainment bias, the standardized incidence ratio was 1.2 (95% confidence interval [CI] 0.99 to 1.3) for total fracture risk and 0.9 (95% CI 0.7 to 1.2) for osteoporotic fracture risk alone. Various breast cancer treatments were associated with an increased risk of fracture, but those associations were strongest for pathologic fractures, which were relatively more common among the women who were premenopausal when their breast cancer was diagnosed. Moreover, underlying clinical characteristics prompting different treatments may have been partially responsible for the associated fracture outcomes (indication bias). These data thus demonstrate that breast cancer patients in general are not at greatly increased risk of fracture but neither are they protected from fractures despite any determinants that breast cancer and high bone density may have in common.

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.

The application of pharmacoeconomic modelling to estimate a value-based price for new cancer drugs

RATIONALE, AIMS AND OBJECTIVES

Value-based pricing has recently been discussed by international bodies as a means to estimate a drug price that is linked to the benefits it offers patients and society. The World Health Organization (WHO) has recommended using three times a country's per capita gross domestic product (GDP) as the threshold for economic value. Using the WHO criteria, pharmacoeconomic modelling was used to illustrate the application of value-based price towards bevacizumab, a relatively new drug that provides a 1.4-month survival benefit to patients with metastatic colorectal cancer (mCRC).

METHODS

A decision model was developed to simulate outcomes in mCRC patients receiving chemotherapy ± bevacizumab. Clinical data were obtained from randomized trials and costs from Canadian cancer centres. Utility estimates were determined by interviewing 24 oncology nurses and pharmacists. A price per dose of bevacizumab was then estimated using a target threshold of $CAD117,000 per quality adjusted life year gained, which is three times the Canadian per capita GDP.

RESULTS

For a 1.4-month survival benefit, a price of $CAD830 per dose would be considered cost-effective from the Canadian public health care perspective. If the drug were able to improve patient quality of life or survival from 1.4 to 3 months, the drug price could increase to $CAD1560 and $CAD2180 and still be considered cost-effective.

DISCUSSION

The use of the WHO criteria for estimating a value-based price is feasible, but a balance between what patients/governments can afford to pay and the commercial viability of the product in the reference country would be required.

Costs and trends in pancreatic cancer treatment

BACKGROUND

Pancreatic cancer poses a substantial morbidity and mortality burden in the United States, and predominantly affects older adults. The objective of this study was to estimate the direct medical costs of pancreatic cancer treatment in a population-based cohort of Medicare beneficiaries, and the contribution of different treatment modalities and health care services to the total cost of care and trends in costs over time.

METHODS

In the linked Surveillance, Epidemiology, and End Results (SEER)-Medicare database, pancreatic cancer patients were identified who were aged 66 years or older and who were diagnosed from 2000 to 2007. Total direct medical costs were estimated from Medicare payments overall and within categories of care. Costs attributable to pancreatic cancer were estimated by subtracting the costs of medical care in a matched cohort of cancer-free beneficiaries.

RESULTS

A total of 15,037 patients were identified, of whom 97% were observed from diagnosis until death. Mean total direct medical costs were $65,500. Mean total costs were greater for patients with resectable locoregional disease ($134,700) than for those with unresectable locoregional or distant disease ($65,300 and $49,000, respectively). Hospitalizations and cancer-directed procedures collectively accounted for the largest fraction of health care costs. The total cost of care appeared to increase slightly over the study period (P = .05). The mean costs attributable to pancreatic cancer were $61,700.

CONCLUSIONS

Despite poor prognosis and short survival, the economic burden of pancreatic cancer in the elderly is substantial. Demographic trends, greater use of targeted therapies, and possible implementation of screening strategies are likely to impact treatment patterns and costs in the future.

Patient survival and healthcare utilization costs after diagnosis of triple-negative breast cancer in a United States managed care cancer registry

BACKGROUND

Triple-negative breast cancer (TNBC) makes up 10-17% of all breast cancers and, due to lack of receptor expression, is unresponsive to therapies that target hormonal receptors or HER2. Unique in its tumor aggression and high rates of recurrence, TNBC is less likely to be detected by mammogram and has a poorer prognosis than other breast cancer subtypes (non-TNBC).

OBJECTIVES

To examine the survival, healthcare utilization, and healthcare cost for women with TNBC compared with non-TNBC breast cancer.

METHODS

The study population was derived from a US managed care cancer registry linked to health insurance claims and social security mortality data. Based on initial type and stage at diagnosis, patients were divided into two cohorts: patients with TNBC and those with non-TNBC. Records were analyzed from initial diagnosis until death, disenrollment, or end of observation period. Survival and annual healthcare utilization and costs were estimated and compared between cohorts after adjusting for baseline demographic characteristics, comorbidities, and prior resource use. Subgroup analyses were performed in patients diagnosed with stage I-III and IV breast cancer.

RESULTS

The study included women diagnosed with TNBC (n = 450) and non-TNBC (n = 1807). Median follow-up time for all patients was 716 days (688.5 and 733 days for TNBC and non-TNBC patients, respectively). After initial diagnosis, overall mortality risk for the TNBC cohort was twice as high as the non-TNBC cohort (HR = 2.02, p < 0.0001). Patients with TNBC had more annual hospitalizations, hospitalized days, and number of emergency room visits relative to non-TNBC. Despite similar annual total healthcare costs, adjusted inpatient costs for patients with non-TNBC averaged 77% higher ($8395 vs. $4745, p < 0.0001). Furthermore, payer reimbursements were higher for TNBC than non-TNBC patients ($8213 vs. $4486, p < 0.0001).

CONCLUSIONS

While it does not control for race or socioeconomic status, this study found that in a US managed care setting, patients with TNBC compared with non-TNBC have significantly shorter survival, accompanied by higher inpatient utilization and healthcare costs.

Contribution of imaging to cancer care costs

Health care costs in the United States are increasing faster than the gross domestic product (GDP), and the growth rate of costs related to diagnostic imaging exceeds those of overall health care expenditures. Here we show that the contribution of imaging to cancer care costs pales in comparison to those of other key cost components, such as cancer drugs. Specifically, we estimate that (18)F-FDG PET or PET/CT accounted for approximately 1.5% of overall Medicare cancer care costs in 2009. Moreover, we propose that the appropriate use of (18)F-FDG PET or PET/CT could reduce the costs of cancer care. Because the U.S. health care system is complex and because it is difficult to find accurate data elsewhere, most cost and use assessments are based on published data from the U.S. Centers for Medicare & Medicaid Services.

Healthcare cost attributable to recently-diagnosed breast cancer in a privately-insured population in the United States

OBJECTIVE

To evaluate breast cancer-associated healthcare cost from the payer perspective for the initial year after diagnoses of invasive breast cancer.

BACKGROUND

Breast cancer is the second most common malignancy in American women. While lifetime burden-of-care studies have reported spending between $20,000 and $100,000 per patient, previous studies have not outlined first year cost in managing this disease in recently diagnosed patients.

METHODS

This study was a retrospective, matched cohort study of privately-insured patients. Data were from a large US employers' health claims database (January 2003-September 2008). Breast cancer cases were identified by ICD-9-CM diagnostic codes on index and confirmatory claims. A control group was identified with a ratio of 3:1, matched by demographic and health plan characteristics. Comorbidities were analyzed using the Charlson comorbidity index and AHRQ Comorbidity Software. A multivariate, log-linked, generalized linear model evaluated cost contributions of breast cancer in relation to demographic factors, comorbidities, and plan type.

RESULTS

The study included 35,057 cases and 105,171 matched controls (mean age 52 years). Common comorbidities included hypertension, diabetes, hypothyroidism, chronic pulmonary disease, and deficiency anemia. In the generalized linear model, the adjusted difference in total healthcare cost was $42,401 per patient within a year, with outpatient services responsible for most of this sum. Breast cancer-associated incremental annual costs per patient in inpatient, outpatient, and prescription categories were $5100, $37,231, and $1037, respectively.

LIMITATIONS

These results may not be representative of the entire US, as data were derived from breast cancer patients with private, employer-based health insurance, and lacked covariates including race/ethnicity, education, income, and disease stage.

CONCLUSIONS

Recently diagnosed breast cancer represents a substantial economic burden for US healthcare payers.

A model to estimate human resource needs for the treatment of outpatients with cancer

PURPOSE

Although personnel costs significantly affect cancer health care expenditures, little is known about the relationship between workload, human resource requirements, and associated costs. An empirical model to forecast staffing demand is described according to the yearly caseload of outpatients with cancer beginning active treatment and the number of personnel working hours.

METHODS

The oncology department at the University Hospital of Udine (Udine, Italy) is a computerized unit taking care of approximately 1,300 patients per year. Each clinical episode is centrally recorded. We queried the database for the total number of consultations per patient beginning treatment during 2006. With predefined bonds (ie, time limit set for each visit type and annual working hours per employee), we sought to estimate yearly per-patient hours of care and the number of personnel needed.

RESULTS

In 2006, each outpatient with cancer beginning active treatment generated an average of 16 clinical evaluations, which in turn translated into 8 and 16 hours of physician and nurse working time, respectively. Assuming an average of 1,672 annual working hours, a need for one physician and three nurses for every 600 patients could be estimated for every 200 novel patients. In the next year, the same caseload induced 4.5 consultations on average; using a similar approach, the demand for additional time and resources was calculated.

CONCLUSION

By means of a simple model combining predefined conditions with a centralized record of clinical episodes, we were able to provide a reasonable estimate of human resource requirements and a tool to forecast the staff expenditures of a cancer unit.

Delivering affordable cancer care in high-income countries

The burden of cancer is growing, and the disease is becoming a major economic expenditure for all developed countries. In 2008, the worldwide cost of cancer due to premature death and disability (not including direct medical costs) was estimated to be US$895 billion. This is not simply due to an increase in absolute numbers, but also the rate of increase of expenditure on cancer. What are the drivers and solutions to the so-called cancer-cost curve in developed countries? How are we going to afford to deliver high quality and equitable care? Here, expert opinion from health-care professionals, policy makers, and cancer survivors has been gathered to address the barriers and solutions to delivering affordable cancer care. Although many of the drivers and themes are specific to a particular field-eg, the huge development costs for cancer medicines-there is strong concordance running through each contribution. Several drivers of cost, such as over-use, rapid expansion, and shortening life cycles of cancer technologies (such as medicines and imaging modalities), and the lack of suitable clinical research and integrated health economic studies, have converged with more defensive medical practice, a less informed regulatory system, a lack of evidence-based sociopolitical debate, and a declining degree of fairness for all patients with cancer. Urgent solutions range from re-engineering of the macroeconomic basis of cancer costs (eg, value-based approaches to bend the cost curve and allow cost-saving technologies), greater education of policy makers, and an informed and transparent regulatory system. A radical shift in cancer policy is also required. Political toleration of unfairness in access to affordable cancer treatment is unacceptable. The cancer profession and industry should take responsibility and not accept a substandard evidence base and an ethos of very small benefit at whatever cost; rather, we need delivery of fair prices and real value from new technologies.

Impact of new drugs and biologics on colorectal cancer treatment and costs

PURPOSE

To compare medical expenditures of patients receiving old and new colorectal cancer (CRC) regimens.

STUDY DESIGN

USING CLAIMS DATA, WE IDENTIFIED TWO COHORTS OF PRIVATELY INSURED PATIENTS DIAGNOSED WITH CRC: first, those diagnosed before new treatment introduction (January 1, 2002, to December 31, 2002), and second, those diagnosed after new treatment introduction (June 1, 2004, to May 31, 2005). CRC diagnosis was identified using International Classification of Diseases-9 codes 153.xx, 154.xx, and 159.0. First- and second-line chemotherapy regimens were identified. Treatments and expenditures were then observed for up to 2 years after initial diagnosis.

METHODS

We estimated multivariate models to measure changes in cost with changes in treatment regimen. Approval dates of new regimens were used as natural experiments.

RESULTS

New regimens, such as fluorouracil, leucovorin, and oxaliplatin (FOLFOX), have rapidly replaced the most prevalent preperiod product (ie, fluorouracil/leucovorin). Changes in treatment have caused large increases in total expenditure, primarily through increases in chemotherapy prices. FOLFOX alone has increased total average cost by 14%. New treatments have not substituted other medical services; rather, they have indirectly raised costs through nonstandard regimen use and increases in second-line treatment use. We found no evidence that expenditure effects were driven by changes in follow-up duration.

CONCLUSION

New CRC treatments have increased both regimen choice and expenditures. New regimens have primarily increased expenditures through direct treatment costs; we observed no offsetting expenditure reductions.

Costs of medical care after open or minimally invasive prostate cancer surgery: a population-based analysis

BACKGROUND

Evidence suggests that minimally invasive radical prostatectomy (MRP) and open radical prostatectomy (ORP) have similar short-term clinical and functional outcomes. MRP with robotic assistance is generally more expensive than ORP, but it is not clear whether subsequent costs of care vary by approach.

METHODS

In the Surveillance, Epidemiology, and End Results (SEER) cancer registry linked with Medicare claims, men aged 66 years or older who received MRP or ORP in 2003 through 2006 for prostate cancer were identified. Total cost of care was estimated as the sum of Medicare payments from all claims for hospital care, outpatient care, physician services, home health and hospice care, and durable medical equipment in the first year from the date of surgical admission. The impact of surgical approach on costs was estimated, controlling for patient and disease characteristics.

RESULTS

Of 5445 surgically treated prostate cancer patients, 4454 (82%) had ORP and 991 (18%) had MRP. Mean total first-year costs were more than $1200 greater for MRP compared with ORP ($16,919 vs $15,692; P = .08). Controlling for patient and disease characteristics, MRP was associated with 2% greater mean total payments, but this difference was not statistically significant. First-year costs were greater for men who were older, black, lived in the Northeast, had lymph node involvement, more advanced tumor stage, or greater comorbidity.

CONCLUSIONS

In this population-based cohort of older men, MRP and ORP had similar economic outcomes. From a payer's perspective, any benefits associated with MRP may not translate to net savings compared with ORP in the first year after surgery.

The economic burden of prostate cancer

In the present review we discuss expenditure on prostate cancer diagnosis, treatment and follow-up and evaluate the cost of prostate cancer and its management in different countries. Prostate cancer costs were identified from published data and internet sources. To provide up-to-date comparisons, costs were inflated to 2010 levels and the most recent exchange rates were applied. A high proportion of the costs are incurred in the first year after diagnosis; in 2006, this amounted to 106.7-179.0 million euros (€) in the European countries where these data were available (UK, Germany, France, Italy, Spain and the Netherlands). In the USA, the total estimated expenditure on prostate cancer was 9.862 billion US dollars ($) in 2006. The mean annual costs per patient in the USA were $10,612 in the initial phase after diagnosis, $2134 for continuing care and $33,691 in the last year of life. In Canada, hospital and drug expenditure on prostate cancer totalled C$103.1 million in 1998. In Australia, annual costs for prostate cancer care in 1993-1994 were 101.1 million Australian dollars. Variations in costs between countries were attributed to differences in incidence and management practices. Per patient costs depend on cancer stage at diagnosis, survival and choice of treatment. Despite declining mortality rates, costs are expected to rise owing to increased diagnosis, diagnosis at an earlier stage and increased survival. Unless new strategies are devised to increase the efficiency of healthcare provision, the economic burden of prostate cancer will continue to rise.

Lobectomy in octogenarians with non-small cell lung cancer: ramifications of increasing life expectancy and the benefits of minimally invasive surgery

BACKGROUND

As the population ages, clinicians are increasingly confronted with octogenarians with resectable non-small cell lung cancer (NSCLC). We reviewed the outcomes of octogenarians who underwent lobectomy for NSCLC by video-assisted thoracic surgery (VATS) versus open thoracotomy, to determine if there was a benefit to the VATS approach in this group.

METHODS

We conducted a retrospective single-institution review of patients age 80 years or greater who underwent a lobectomy for NSCLC from 1998 to 2009. Outcomes including complication rates, length of stay, disposition, and long-term survival were analyzed.

RESULTS

One hundred twenty-one octogenarians underwent lobectomy: 40 VATS and 81 through open thoracotomy. Compared with thoracotomy, VATS patients had fewer complications (35.0% vs 63.0%, p = 0.004), shorter length of stay (5 vs 6 days, p = 0.001), and were less likely to require admission to the intensive care unit (2.5% vs 14.8%, p = 0.038) or rehabilitation after discharge (5% vs 22.5%, p = 0.015). In multivariate analysis, VATS was an independent predictor of reduced complications (odds ratio, 0.35; 95% confidence interval, 0.15 to 0.84; p = 0.019). Survival comparisons demonstrated no significant difference between the two techniques, either in univariate analysis of stage I patients (5-year VATS, 76.0%; thoracotomy, 65.3%; p = 0.111) or multivariate analysis of the entire cohort (adjusted hazard ratio, 0.59; 95% confidence interval, 0.27 to 1.28; p = 0.183).

CONCLUSIONS

Octogenarians with NSCLC can undergo resection with low mortality and survival among stage I patients, which is comparable with the general lung cancer population. The VATS approach to resection reduces morbidity in this age demographic, resulting in shorter, less intensive hospitalization, and less frequent need for postoperative rehabilitation.

Economic burden of cancer in the United States: estimates, projections, and future research

The economic burden of cancer in the United States is substantial and expected to increase significantly in the future because of expected growth and aging of the population and improvements in survival as well as trends in treatment patterns and costs of care following cancer diagnosis. In this article, we describe measures of the economic burden of cancer and present current estimates and projections of the national burden of cancer in the United States. We discuss ongoing efforts to characterize the economic burden of cancer in the United States and identify key areas for future work including developing and enhancing research resources, improving estimates and projections of economic burden, evaluating targeted therapies, and assessing the financial burden for patients and their families. This work will inform efforts by health care policy makers, health care systems, providers, and employers to improve the cancer survivorship experience in the United States.

Controlling the cost of breast cancer

Breast cancer management is an important part of the health-care system. In the current harsh economic climate, these costs have to be controlled, and achieving this without compromising quality of care is a daunting challenge. This article discusses the need to find effective and well-targeted chemotherapeutic regimens, which, when combined with appropriate implementation of novel strategies, will provide the optimum treatment for patients while maintaining economic viability.

The burden of depression in prostate cancer

OBJECTIVE

We sought to analyze the prevalence and incremental burden of depression among elderly with prostate cancer.

METHODS

We adopted a retrospective cohort design using the Surveillance, Epidemiology and End Results-Medicare linked database between 1995 and 2003. Patients with prostate cancer diagnosed between 1995 and 1998 were identified and followed retrospectively for 1 year pre-diagnosis and up to 8 years post diagnosis. In this cohort of patients with prostate cancer, depression during treatment phase (1 year after diagnosis of prostate cancer) or in the follow-up phase was identified using the International Classification of Diseases-Ninth Revision depression-related codes. Poisson, general linear (log-link) and Cox regression models were used to determine the association between depression status during treatment and follow-up phases and outcomes-health resource utilization, cost and mortality.

RESULTS

Of the 50,147 patients newly diagnosed with prostate cancer, 4285 (8.54%) had a diagnosis of depression. A diagnosis of depression during treatment phase was associated with higher odds of emergency room visits (odds ratio (OR) = 4.45, 95% CI = 4.13, 4.80), hospitalizations (OR = 3.22, CI = 3.08, 3.37), outpatient visits (OR = 1.71, CI = 1.67, 1.75) and excess risk of death over the course of the follow-up interval (hazard ratio = 2.82, CI = 2.60, 3.06). Health care costs associated with depression remained elevated compared with costs for men without depression, over the course of the follow-up.

CONCLUSIONS

Depression during the treatment phase was associated with significant health resource utilization, costs and mortality among men with prostate cancer. These findings emphasize the need to effectively identify and treat depression in the setting of prostate cancer.

The role of stereotactic ablative radiotherapy for early-stage and oligometastatic non-small cell lung cancer: evidence for changing paradigms

A compelling body of non-randomized evidence has established stereotactic ablative lung radiotherapy (SABR) as a standard of care for medically inoperable patients with peripheral early-stage non-small cell lung cancer (NSCLC). This convenient outpatient therapy, which is typically delivered in 3-8 fractions, is also well tolerated by elderly and frail patients, makes efficient use of resources and is feasible using standard commercial equipment. The introduction of lung SABR into large populations has led to an increased utilization of radiotherapy, a reduction in the proportion of untreated patients and an increase in overall survival. In selected patients, the same ablative technology can now achieve durable local control of NSCLC metastases in a variety of common locations including the adrenal glands, bone, brain, and liver. At the same time as this, advances in prognostic molecular markers and targeted systemic therapies mean that there is now a subgroup of patients with stage IV NSCLC and a median survival of around 2 years. This creates opportunities for new trials that incorporate SABR and patient-specific systemic strategies. This selective mini-review focuses on the emerging role of SABR in patients with early-stage and oligometastatic NSCLC.

Gene expression profile testing for breast cancer and the use of chemotherapy, serious adverse effects, and costs of care

As gene expression profile (GEP) testing for breast cancer may provide additional prognostic information to guide the use of adjuvant chemotherapy, we examined the association between GEP testing and use of chemotherapy, serious chemotherapy-related adverse effects, and total charges during the 12 months following diagnosis. Medical record review was conducted for women age 30-64 years, with incident, non-metastatic, invasive breast cancer diagnosed 2006-2008 in a large, national health plan. Of 534 patients, 25.8% received GEP testing, 68.2% received chemotherapy, and 10.5% experienced a serious chemotherapy-related adverse effect. GEP testing was most commonly used in women at moderate clinical risk of recurrence (52.0 vs. 25.0% of low-risk women and 5.5% of high-risk). Controlling for the propensity to receive GEP testing, women who had GEP were less likely to receive chemotherapy (propensity adjusted odds ratio, 95% confidence interval 0.62, 0.39-0.99). Use of GEP was associated with more chemotherapy use among women at low risk based on clinical characteristics (OR = 42.19; CI 2.50-711.82), but less use among women with a high risk based on clinical characteristics (OR = 0.12; CI 0.03-0.47). Use of GEP was not associated with chemotherapy for the moderate risk group. There was no significant relationship between GEP use and either serious chemotherapy-associated adverse effects or total charges. While GEP testing was associated with an overall decrease in adjuvant chemotherapy, we did not find differences in serious chemotherapy-associated adverse events or charges during the 12 months following diagnosis.

Systems Modeling in Integrative Oncology

Systems modeling provides an integrated framework to capture and analyze diverse and multidisciplinary data in a standardized manner. The authors present the Integrative Oncology Systems Model (IOSM) to help assess the impact of behavior modification and various therapeutic interventions on cancer development and progression and the resultant effect on survival and quality of life outcomes.

National estimates of out-of-pocket health care expenditure burdens among nonelderly adults with cancer: 2001 to 2008

PURPOSE

To compare the prevalence of high out-of-pocket burdens among patients with cancer with other chronically ill and well patients, and to examine the sociodemographic characteristics associated with high burdens among patients with cancer.

METHODS

The sample included persons 18 to 64 years of age who received treatment for cancer, taken from a nationally representative sample of the US population from the 2001 to 2008 Medical Expenditure Panel Survey. We examined the proportion of persons living in families with high out-of-pocket burdens associated with medical spending, including insurance premiums, relative to income, defining high health care (total) burden as spending more than 20% of income on health care (and premiums).

RESULTS

The risk of high burdens is significantly greater for patients with cancer compared with other chronically ill and well patients. We find that 13.4% of patients with cancer had high total burdens, in contrast to 9.7% among those with other chronic conditions and 4.4% among those without chronic conditions. Among nonelderly persons with cancer, the following were associated with higher out-of-pocket burdens: private nongroup insurance, age 55 to 64 years, non-Hispanic black, never married or widowed, one child or no children, unemployed, lower income, lower education level, living in nonmetropolitan statistical areas, and having other chronic conditions.

CONCLUSION

High burdens may affect treatment choice and deter patients from getting care. Thus, although a detailed patient-physician discussion of costs of care may not be feasible, we believe that an awareness of out-of-pocket burdens among patients with cancer is useful for clinical oncologists.
