Projections of the Cost of Cancer Care in the United States: 2010–2020

BACKGROUND Current estimates of the costs of cancer care in the United States are based on data from 2003 and earlier. However, incidence, survival, and practice patterns have been changing for the majority of cancers. METHODS Cancer prevalence was estimated and projected by phase of care (initial year following diagnosis, continuing, and last year of life) and tumor site for 13 cancers in men and 16 cancers in women through 2020. Cancer prevalence was calculated from cancer incidence and survival models estimated from Surveillance, Epidemiology, and End Results (SEER) Program data. Annualized net costs were estimated from recent SEER-Medicare linkage data, which included claims through 2006 among beneficiaries aged 65 years and older with a cancer diagnosis. Control subjects without cancer were identified from a 5% random sample of all Medicare beneficiaries residing in the SEER areas to adjust for expenditures not related to cancer. All cost estimates were adjusted to 2010 dollars. Different scenarios for assumptions about future trends in incidence, survival, and cost were assessed with sensitivity analysis. RESULTS Assuming constant incidence, survival, and cost, we projected 13.8 and 18.1 million cancer survivors in 2010 and 2020, respectively, with associated costs of cancer care of 124.57 and 157.77 billion 2010 US dollars. This 27% increase in medical costs reflects US population changes only. The largest increases were in the continuing phase of care for prostate cancer (42%) and female breast cancer (32%). Projections of current trends in incidence (declining) and survival (increasing) had small effects on 2020 estimates. However, if costs of care increase annually by 2% in the initial and last year of life phases of care, the total cost in 2020 is projected to be

173 billion, which represents a 39% increase from 2010. CONCLUSIONS The national cost of cancer care is substantial and expected to increase because of population changes alone. Our findings have implications for policy makers in planning and allocation of resources.

Care for the caregivers: a review of self-report instruments developed to measure the burden, needs, and quality of life of informal caregivers

BACKGROUND Timely estimates of the costs of care for cancer patients are an important element in the formulation of national cancer programs and policies. We estimated net costs of care for elderly cancer patients in the United States for the 18 most prevalent cancers and for all other tumor sites combined. METHODS We used Surveillance, Epidemiology, and End Results-Medicare files to identify 718,907 cancer patients and 1,623,651 noncancer control subjects. Within each tumor site, noncancer control subjects were matched to patients by sex, age group, geographic location, and phase of care (ie, initial, continuing, and last year of life). Costs of care were estimated for each phase by use of Medicare claims data from January 1, 1999, through December 31, 2003. Per-patient net costs of care were applied to the 5-year survival of cancer patients by phase of care to estimate 5-year costs of care and extrapolated to the elderly US Medicare population diagnosed with cancer in 2004. RESULTS Across tumor sites, mean net costs of care were highest in the initial and last year of life phases of care and lowest in the continuing phase. Mean 5-year net costs varied widely, from less than

21.1 billion. Costs to Medicare were highest for lung, colorectal, and prostate cancers, reflecting underlying incidence, stage distribution at diagnosis, survival, and phase-specific costs for these tumor sites. CONCLUSIONS The costs of cancer care to Medicare are substantial and vary by tumor site, phase of care, stage at diagnosis, and survival.

Productivity Costs of Cancer Mortality in the United States: 2000–2020

Significant demands are being placed on the informal caregivers of chronically ill patients, including those suffering from cancer. Health care professionals need to be aware of these demands, and they need effective tools to assess the impact these demands place on the caregivers. Over the past 25 years, researchers have developed self-report instruments to assess informal caregivers. These instruments assess various aspects of the caregiving experience, including caregiver burden, needs, and quality of life. The purpose of this review was to identify and critically evaluate these instruments. MEDLINE and PUBMED were searched from 1966 to 2002. After an extensive literature search and review, and utilizing specific inclusion criteria, 28 instruments were identified and evaluated in terms of their development, content, and psychometric properties. In addition, a history of the construct and measurement development in the areas of caregiver burden, needs, and quality of life are discussed. Although some further development and refinement of instruments could benefit the field, depending on the questions researchers or clinicians seek to pursue, there are many proven tools available for their use. Future research needs to use these instruments to assess the effectiveness of interventions aimed at improving the care of the caregivers.

Economic Burden of Cancer Survivorship Among Adults in the United States

BACKGROUND Despite reports of increases in the cost of cancer treatment, little is known about how costs of cancer treatment have changed over time and what services have contributed to the increases. METHODS We used data from the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database for 306,709 persons aged 65 and older and diagnosed with breast, lung, colorectal, or prostate cancer between 1991 and 2002 to assess the number of patients assigned to initial cancer care, from 2 months before diagnosis to 12 months after diagnosis, and mean annual Medicare payments for this care according to cancer type and type of treatment. Mutually exclusive treatment categories were cancer-related surgery, chemotherapy, radiation therapy, and other hospitalizations during the period of initial cancer care. Linear regression models were used to assess temporal trends in the percentage of patients receiving treatment and costs for those treated. We extrapolated our results based on the SEER data to the US Medicare population to estimate national Medicare payments by cancer site and treatment category. All statistical tests were two-sided. RESULTS For patients diagnosed in 2002, Medicare paid an average of
