Purpose: Radiation therapy represents a major source of health care expenditure for patients with cancer. Understanding the sources of variability in the cost of radiation therapy is critical to evaluating the efficiency of the current reimbursement system and could shape future policy reform. This study defines the magnitude and sources of variation in the cost of radiation therapy for a large cohort of Medicare beneficiaries., Patients and Methods: We identified 55,288 patients within the SEER database diagnosed with breast, lung, or prostate cancer between 2004 and 2009. The cost of radiation therapy was estimated from Medicare reimbursements. Multivariable linear regression models were used to assess the influence of patient, tumor, and radiation therapy provider characteristics on variation in cost of radiation therapy., Results: For breast, lung, and prostate cancers, the median cost (interquartile range) of a course of radiation therapy was $8,600 ($7,300 to $10,300), $9,000 ($7,500 to $11,100), and $18,000 ($11,300 to $25,500), respectively. For all three cancer subtypes, patient- or tumor-related factors accounted for < 3% of the variation in cost. Factors unrelated to the patient, including practice type, geography, and individual radiation therapy provider, accounted for a substantial proportion of the variation in cost, ranging from 44% with breast, 43% with lung, and 61% with prostate cancer., Conclusion: In this study, factors unrelated to the individual patient accounted for the majority of variation in the cost of radiation therapy, suggesting potential inefficiency in health care expenditure. Future research should determine whether this variability translates into improved patient outcomes for further evaluation of current reimbursement practices., (Copyright © 2015 by American Society of Clinical Oncology.)

PurposeAdjuvant radiation therapy, which has proven benefit against breast cancer, has historically been associated with an increased incidence of ischemic heart disease. Modern techniques have reduced this risk, but a detailed evaluation has not recently been conducted. The present study evaluated the effect of current radiation practices on ischemia-related cardiac events and procedures in a population-based study of older women with nonmetastatic breast cancer.Methods and materialsA total of 29,102 patients diagnosed from 2000 to 2009 were identified from the Surveillance, Epidemiology, and End Results-Medicare database. Medicare claims were used to identify the radiation therapy and cardiac outcomes. Competing risk models were used to assess the effect of radiation on these outcomes.ResultsPatients with left-sided breast cancer had a small increase in their risk of percutaneous coronary intervention (PCI) after radiation therapy-the 10-year cumulative incidence for these patients was 5.5% (95% confidence interval [CI] 4.9%-6.2%) and 4.5% (95% CI 4.0%-5.0%) for right-sided patients. This risk was limited to women with previous cardiac disease. For patients who underwent PCI, those with left-sided breast cancer had a significantly increased risk of cardiac mortality with a subdistribution hazard ratio of 2.02 (95% CI 1.23-3.34). No other outcome, including cardiac mortality for the entire cohort, showed a significant relationship with tumor laterality.ConclusionsFor women with a history of cardiac disease, those with left-sided breast cancer who underwent radiation therapy had increased rates of PCI and a survival decrement if treated with PCI. The results of the present study could help cardiologists and radiation oncologists better stratify patients who need more aggressive cardioprotective techniques.

Purpose Palliative care's role in oncology has expanded, but its effect on aggressiveness of care at the end of life has not been characterized at the population level. Methods This matched retrospective cohort study examined the effect of an encounter with palliative care on health-care use at the end of life among 6,580 Medicare beneficiaries with advanced prostate, breast, lung, or colorectal cancer. We compared health-care use before and after palliative care consultation to a matched nonpalliative care cohort. Results The palliative care cohort had higher rates of health-care use in the 30 days before palliative care consultation compared with the nonpalliative cohort, with higher rates of hospitalization (risk ratio [RR], 3.33; 95% CI, 2.87 to 3.85), invasive procedures (RR, 1.75; 95% CI, 1.62 to 1.88) and chemotherapy administration (RR, 1.61; 95% CI, 1.45 to 1.78). The opposite pattern emerged in the interval from palliative care consultation through death, where the palliative care cohort had lower rates of hospitalization (RR, 0.53;95%CI, 0.44-0.65), invasive procedures (RR, 0.52; 95% CI, 0.45 to 0.59) and chemotherapy administration (RR, 0.46; 95% CI, 0.39 to 0.53). Patients with earlier palliative care consultation in their disease course had larger absolute reductions in health-care use compared with those with palliative care consultation closer to the end of life. Conclusion This population-based study found that palliative care substantially decreased health-care use among Medicare beneficiaries with advanced cancer. Given the increasing number of elderly patients with advanced cancer, this study emphasizes the importance of early integration of palliative care alongside standard oncologic care.

Background and purpose In cost-effective healthcare systems, the cost of services should parallel patient complexity or quality of care. The purpose of this study was to determine whether the cost of radiotherapy correlates with patient-related outcomes among a large cohort of breast cancer patients treated with adjuvant breast radiation. Materials and methods 23,127 women with non-metastatic breast cancer undergoing radiotherapy after breast conservation surgery were identified from the Surveillance, Epidemiology, and End Results database from 2000 to 2009. Medicare reimbursements were used as a proxy for cost of radiotherapy, and Medicare claims were examined to identify local toxicities, and breast cancer-related endpoints. The impact of cost on these outcomes was studied with multivariable Fine-Gray models to account for competing risks. Results The median cost (and interquartile range) of a course of breast radiation was $8100 ($6700–9700). Increased radiation costs were not associated with the occurrence of treatment-related toxicities (all p -values > 0.05), ipsilateral breast recurrence ( p = 0.55), or breast cancer-related mortality ( p = 0.55). Conclusion Higher costs for adjuvant radiation in breast cancer were not associated with a decreased risk of patient-related outcomes suggesting inefficiency in Medicare reimbursements. Future efforts should focus on prospective evaluation of alternative payment models for radiotherapy. [ABSTRACT FROM AUTHOR]
