Age Disparity in Palliative Radiation Therapy Among Patients With Advanced Cancer

PURPOSE/OBJECTIVE Palliative radiation therapy represents an important treatment option among patients with advanced cancer, although research shows decreased use among older patients. This study evaluated age-related patterns of palliative radiation use among an elderly Medicare population. METHODS AND MATERIALS We identified 63,221 patients with metastatic lung, breast, prostate, or colorectal cancer diagnosed between 2000 and 2007 from the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database. Receipt of palliative radiation therapy was extracted from Medicare claims. Multivariate Poisson regression analysis determined residual age-related disparity in the receipt of palliative radiation therapy after controlling for confounding covariates including age-related differences in patient and demographic covariates, length of life, and patient preferences for aggressive cancer therapy. RESULTS The use of radiation decreased steadily with increasing patient age. Forty-two percent of patients aged 66 to 69 received palliative radiation therapy. Rates of palliative radiation decreased to 38%, 32%, 24%, and 14% among patients aged 70 to 74, 75 to 79, 80 to 84, and over 85, respectively. Multivariate analysis found that confounding covariates attenuated these findings, although the decreased relative rate of palliative radiation therapy among the elderly remained clinically and statistically significant. On multivariate analysis, compared to patients 66 to 69 years old, those aged 70 to 74, 75 to 79, 80 to 84, and over 85 had a 7%, 15%, 25%, and 44% decreased rate of receiving palliative radiation, respectively (all P<.0001). CONCLUSIONS Age disparity with palliative radiation therapy exists among older cancer patients. Further research should strive to identify barriers to palliative radiation among the elderly, and extra effort should be made to give older patients the opportunity to receive this quality of life-enhancing treatment at the end of life.

Cancer Cachexia: Beyond Weight Loss

Cancer cachexia is a multifactorial syndrome characterized by skeletal muscle loss leading to progressive functional impairment. Despite the ubiquity of cachexia in clinical practice, prevention, early identification, and intervention remain challenging. The impact of cancer cachexia on quality of life, treatment-related toxicity, physical function, and mortality are well established; however, establishing a clinically meaningful definition has proven challenging because of the focus on weight loss alone. Attempts to more comprehensively define cachexia through body composition, physical functioning, and molecular biomarkers, while promising, are yet to be routinely incorporated into clinical practice. Pharmacologic agents that have not been approved by the US Food and Drug Administration but that are currently used in cancer cachexia (ie, megestrol, dronabinol) may improve weight but not outcomes of interest such as muscle mass, physical activity, or mortality. Their routine use is limited by adverse effects. For the practicing oncologist, early identification and management of cachexia is critical. Oncologists must recognize cachexia beyond weight loss alone, focusing instead on body composition and physical functioning. In fact, becoming emaciated is a late sign of cachexia that characterizes its refractory stage. Given that cachexia is a multifactorial syndrome, it requires early identification and polymodal intervention, including optimal cancer therapy, symptom management, nutrition, exercise, and psychosocial support. Consequently, oncologists have a role in ensuring that these resources are available to their patients. In addition, in light of the promising investigational agents, it remains imperative to refer patients with cachexia to clinical trials so that available options can be expanded to effectively treat this pervasive problem.

The development of a prediction tool to identify cancer patients at high risk for chemotherapy-induced nausea and vomiting

Background Despite the availability of effective antiemetics and evidence-based guidelines, up to 40% of cancer patients receiving chemotherapy fail to achieve complete nausea and vomiting control. In addition to type of chemotherapy, several patient-related risk factors for chemotherapy-induced nausea and vomiting (CINV) have been identified. To incorporate these factors into the optimal selection of prophylactic antiemetics, a repeated measures cycle-based model to predict the risk of ≥ grade 2 CINV (≥2 vomiting episodes or a decrease in oral intake due to nausea) from days 0 to 5 post-chemotherapy was developed. Patients and methods Data from 1198 patients enrolled in one of the five non-interventional CINV prospective studies were pooled. Generalized estimating equations were used in a backwards elimination process with the P-value set at <0.05 to identify the relevant predictive factors. A risk scoring algorithm (range 0–32) was then derived from the final model coefficients. Finally, a receiver-operating characteristic curve (ROCC) analysis was done to measure the predictive accuracy of the scoring algorithm. Results Over 4197 chemotherapy cycles, 42.2% of patients experienced ≥grade 2 CINV. Eight risk factors were identified: patient age <60 years, the first two cycles of chemotherapy, anticipatory nausea and vomiting, history of morning sickness, hours of sleep the night before chemotherapy, CINV in the prior cycle, patient self-medication with non-prescribed treatments, and the use of platinum or anthracycline-based regimens. The ROC analysis indicated good predictive accuracy with an area-under-the-curve of 0.69 (95% CI: 0.67–0.70). Before to each cycle of therapy, patients with risk scores ≥16 units would be considered at high risk for developing ≥grade 2 CINV. Conclusions The clinical application of this prediction tool will be an important source of individual patient risk information for the oncology clinician and may enhance patient care by optimizing the use of the antiemetics in a proactive manner.

Antiemesis, version 2.2017 featured updates to the NCCN guidelines

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Antiemesis address all aspects of management for chemotherapy-induced nausea and vomiting. These NCCN Guidelines Insights focus on recent updates to the NCCN Guidelines for Antiemesis, specifically those regarding carboplatin, granisetron, and olanzapine.

Concordance of Advance Care Plans With Inpatient Directives in the Electronic Medical Record for Older Patients Admitted From the Emergency Department

CONTEXT Measuring What Matters identified quality indicators to examine the percentage of patients with documentation of a surrogate decision maker and preferences for life-sustaining treatments. OBJECTIVES To determine the rate of advance care planning in older adults presenting to the emergency department (ED) and translation into medical directives in the electronic medical record (EMR). METHODS A convenience sample of adults 65 years or older was recruited from a large urban ED beginning in January 2012. We administered a baseline interview and survey in English or Spanish, including questions about whether patients had a documented health care proxy or living will. For patients admitted to the hospital who had a health care proxy or living will, chart abstraction was performed to determine whether their advance care preferences were documented in the EMR. RESULTS From February 2012 to May 2013, 53.8% (367 of 682) of older adults who completed the survey in the ED reported having a health care proxy, and 40.2% (274 of 682) had a living will. Of those admitted to the hospital, only 4% (4 of 94) of patients who said they had a living will had medical directives documented in the EMR. Similarly, only 4% (5 of 115) of patients who had a health care proxy had the persons name or contact information documented in their medical record. CONCLUSION About half of the patients 65 years or older arriving in the ED have done significant advance care planning, but most plans are not recorded in the EMR.

Novel investigational biologics for the treatment of cancer cachexia

Introduction: Cancer cachexia is a complex multifactorial syndrome characterized by ongoing, irreversible skeletal muscle loss, leading to progressive functional impairment. Several investigational biologics targeting key inflammatory pathways and/or the myostatin/activin type II receptor pathway are in development. Areas covered: Novel therapies include ALD518, MABp1, IP-1510, OHR/AVR118, bimagrumab and REGN1033 and are discussed. For each investigational therapy, the mechanism of action, preclinical data, cachexia definition, indication and clinical data are discussed. Expert opinion: A critical look of the study protocols and two key challenges limiting the successful evaluation of these agents include: i) lack of a clinically meaningful cachexia definition; and ii) identification and treatment of cachexia in late stage. We describe our observations and clinical experience in an effort to redirect and promote successful strategies to evaluate these novel investigational biologics.

A Single-Center, Retrospective Analysis Evaluating the Utilization of the Opioid Risk Tool in Opioid-Treated Cancer Patients

ABSTRACT The Opioid Risk Tool (ORT) is a screening tool used to assess risk of opioid misuse by stratifying aberrant drug-seeking behaviors and/or identifying known risk factors for drug abuse. The objectives of this study were to risk stratify opioid misuse in a cancer pain population and determine the most common patient risk factors associated with misuse utilizing the ORT. This was a retrospective analysis conducted at an academic comprehensive cancer center. Patients were referred by an oncologist or hematologist to an outpatient palliative care clinic. One-hundred and fourteen patients with cancer (n = 107) or sickle cell disease (n = 7) were evaluated from July 2012 to July 2013. During the clinical interview, patients responded to a clinician administered ORT. Based on the ORT score, patients were stratified into low, moderate, or high risk for opioid misuse. Sample size included 57 men and 57 women. Sixty-five, 21, and 28 patients were deemed low, moderate, and high risk based on the ORT, respectively. The most common risk factors for opioid misuse were a history of depression (women = 32; men = 22) and family history of alcohol abuse (women = 26; men = 22). There was no difference between men and women in the prevalence of depression (P = .17) or family history of alcohol abuse (P = .57). The least common risk factor was a personal history of prescription drug abuse (n = 1) in women and history of preadolescent sexual abuse in men (n = 0). Twenty-five percent (n = 28) of the sample population were deemed high risk based on the ORT. Screening of cancer patients in the palliative care setting suggests that risk factors for opioid misuse exist. Stratifying patients based on a routine screening tool may help identify cancer patients at risk for aberrant drug behaviors.

Adherence to Measuring What Matters Measures Using Point-of-Care Data Collection Across Diverse Clinical Settings

CONTEXT Measuring What Matters (MWM) for palliative care has prioritized data collection efforts for evaluating quality in clinical practice. How these measures can be implemented across diverse clinical settings using point-of-care data collection on quality is unknown. OBJECTIVES To evaluate the implementation of MWM measures by exploring documentation of quality measure adherence across six diverse clinical settings inherent to palliative care practice. METHODS We deployed a point-of-care quality data collection system, the Quality Data Collection Tool, across five organizations within the Palliative Care Research Cooperative Group. Quality measures were recorded by clinicians or assistants near care delivery. RESULTS During the study period, 1989 first visits were included for analysis. Our population was mostly white, female, and with moderate performance status. About half of consultations were seen on hospital general floors. We observed a wide range of adherence. The lowest adherence involved comprehensive assessments during the first visit in hospitalized patients in the intensive care unit (2.71%); the highest adherence across all settings, with an implementation of >95%, involved documentation of management of moderate/severe pain. We observed differences in adherence across clinical settings especially with MWM Measure #2 (Screening for Physical Symptoms, range 45.7%-81.8%); MWM Measure #5 (Discussion of Emotional Needs, range 46.1%-96.1%); and MWM Measure #6 (Documentation of Spiritual/Religious Concerns, range 0-69.6%). CONCLUSION Variations in clinician documentation of adherence to MWM quality measures are seen across clinical settings. Additional studies are needed to better understand benchmarks and acceptable ranges for adherence tailored to various clinical settings.

Early Palliative Care for Patients with Hematologic Malignancies: Is It Really so Difficult to Achieve?

Evidence points to many benefits of “early palliative care,” the provision of specialist palliative care services upstream from the end of life, to improve patients’ quality of life while living with a serious illness. Yet most trials of early palliative care have not included patients with hematologic malignancies. Unfortunately, patients with hematologic malignancies are also known to have substantial illness burden, poor quality of life, and aggressive care at the end of life, including a greater likelihood of dying in the hospital, receiving chemotherapy at the end of life, and low hospice utilization, compared to patients with solid tumors. Given these unmet needs, one must wonder, why is palliative care so underutilized in this population? In this article, we discuss barriers to palliative care integration in hematology, highlight several reports of successful integration, and suggest specific indications for involving palliative care in the management of hematologic malignancy patients.

Spanning the canyon between stem cell transplantation and palliative care

Stem cell transplantation (SCT) and palliative care (PC) may initially appear to be distant extremes in the continuum of care of patients with hematologic malignancies, opposed by multiple obstacles preventing their integration. Rather, we will posit that both fields share many similarities and have much to learn from one another. PC has increasing relevance in cancer care given recent studies that link PC to improved quality-of-life, survival, and decreased cost of care. Understanding modern conceptualizations of PC and its role within SCT is key. Through the report of a single academic medical center experience with an integrated SCT and PC model over the last decade, we will discuss future opportunities for strengthening collaboration between SCT and PC. PC in SCT should be considered from the day of diagnosis and tied to need, not to prognosis.
