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.

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.

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.

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.

    ABSTRACT: PURPOSE: There are currently more than 12 million cancer survivors in the USA. Survivors face many issues related to cancer and treatment that are outside the purview of the clinical care system. Therefore, understanding and providing for the evolving needs of cancer survivors offers challenges and opportunities for the public health system. In 2004, the Centers for Disease Control and Prevention and the Lance Armstrong Foundation, now the Livestrong Foundation, partnered with national cancer survivorship organizations to develop the National Action Plan for Cancer Survivorship (NAPCS). This plan outlines public health strategies to address the needs of cancer survivors. To date, no assessment of NAPCS strategies and their alignment with domestic cancer survivorship activities has been conducted. METHODS: The activities of five national organizations with organized public health agendas about cancer survivorship were assessed qualitatively during 2003-2007. Using the NAPCS as an organizing framework, interviews were conducted with key informants from all participating organizations. Interview responses were supplemented with relevant materials from informants and reviews of the organizations' websites. RESULTS: Strategies associated with surveillance and applied research; communication, education, and training; and programs, policy, and infrastructure represent a large amount of the organizational efforts. However, there are gaps in research on preventive interventions, evaluation of implemented activities, and translation. CONCLUSIONS: Numerous NAPCS strategies have been implemented. Future efforts of national cancer survivorship organizations should include rigorous evaluation of implemented activities, increased translation of research to practice, and assessment of dissemination efforts. IMPLICATIONS FOR CANCER SURVIVORS: The results of this descriptive assessment provide cancer survivors, cancer survivorship organizations, researchers, providers, and policy makers with initial information about cancer survivorship public health efforts in the USA. Additionally, results suggest areas in need of further attention and next steps in advancing the national cancer survivorship public health agenda.

    ABSTRACT: Routine follow-up care is recommended to promote the well-being of cancer survivors, but financial difficulties may interfere. Rural-urban disparities in forgoing healthcare due to cost have been observed in the general population; however, it is unknown whether this disparity persists among survivors. The purpose of this study was to examine rural-urban disparities in forgoing healthcare after cancer due to cost. We analyzed data from 7,804 cancer survivors in the 2006 to 2010 National Health Interview Survey. Logistic regression models, adjusting for sociodemographic and clinical characteristics, were used to assess rural-urban disparities in forgoing medical care, prescription medications, and dental care due to cost, stratified by age (younger: 18-64, older: 65+). Compared with urban survivors, younger rural survivors were more likely to forgo medical care (P < 0.001) and prescription medications (P < 0.001) due to cost; older rural survivors were more likely to forgo medical (P < 0.001) and dental care (P = 0.05). Rural-urban disparities did not persist among younger survivors in adjusted analyses; however, older rural survivors remained more likely to forgo medical [OR = 1.66, 95% confidence interval (CI) = 1.11-2.48] and dental care (OR = 1.54, 95%CI = 1.08-2.20). Adjustment for health insurance and other sociodemographic characteristics attenuates rural-urban disparities in forgoing healthcare among younger survivors, but not older survivors. Financial factors relating to healthcare use among rural survivors should be a topic of continued investigation. Addressing out-of-pocket costs may be an important step in reducing rural-urban disparities in healthcare, especially for older survivors. It will be important to monitor how healthcare reform efforts impact disparities observed in this vulnerable population. Cancer Epidemiol Biomarkers Prev; 22(10); 1668-76. ©2013 AACR.

    ABSTRACT: /st>Bevacizumab, the first FDA-approved anti-angiogenesis agent, has been used for metastatic colorectal cancer since 2004. This study evaluated the utilization of bevacizumab among elderly metastatic colorectal cancer patients in the United States. /st>Using Surveillance and Epidemiology and End RESULTS: (SEER)-Medicare data, this retrospective cohort study consisted of individuals aged 65 years or older with a colorectal cancer diagnosis between 2005 and 2009, who received chemotherapy any time through 2010. This included patients with newly diagnosed metastatic colorectal cancer and patients who progressed from initially diagnosed earlier-stage disease. We ascertained comorbid conditions using ICD-9 codes and conducted logistic regression to identify patients' characteristics associated with bevacizumab use. A total of 8645 patients were identified (mean age 74 years; 52% male); 57% of patients received bevacizumab with initially diagnosed metastatic colorectal cancer and 44% of patients with treated progressive or recurrent disease. After adjusting for other covariates, we found that patients aged ≥80 years were less likely to receive bevacizumab compared with those aged 65-69 years (odds ratio (OR), 0.64 (95% confidence interval (CI): 0.57-0.73)), or if they had evidence of comorbid cardiomyopathy/congestive heart failure (OR, 0.82 (CI: 0.70-0.95)) or arrhythmic disorder (OR, 0.85 (CI: 0.75-0.96)). Adoption of bevacizumab into practice was rapid following its approval, and the use increased from 36% to 40% from 2005 to 2010 (p = 0.013). There were significant regional variations in bevacizumab use. /st>Despite rapid uptake since its original approval, there appears to be low use of bevacizumab in elderly metastatic colorectal cancer patients in the United States. Regional variations and the strong effects of age and comorbidity suggest lack of consensus among oncologists regarding benefits and risks of bevacizumab in elderly patients.
