BACKGROUND Patients with advanced cancer have reduced quality of life, which tends to worsen towards the end of life. We assessed the effect of early palliative care in patients with advanced cancer on several aspects of quality of life. METHODS The study took place at the Princess Margaret Cancer Centre (Toronto, ON, Canada), between Dec 1, 2006, and Feb 28, 2011. 24 medical oncology clinics were cluster randomised (in a 1:1 ratio, using a computer-generated sequence, stratified by clinic size and tumour site [four lung, eight gastrointestinal, four genitourinary, six breast, two gynaecological]), to consultation and follow-up (at least monthly) by a palliative care team or to standard cancer care. Complete masking of interventions was not possible; however, patients provided written informed consent to participate in their own study group, without being informed of the existence of another group. Eligible patients had advanced cancer, European Cooperative Oncology Group performance status of 0-2, and a clinical prognosis of 6-24 months. Quality of life (Functional Assessment of Chronic Illness Therapy--Spiritual Well-Being [FACIT-Sp] scale and Quality of Life at the End of Life [QUAL-E] scale), symptom severity (Edmonton Symptom Assessment System [ESAS]), satisfaction with care (FAMCARE-P16), and problems with medical interactions (Cancer Rehabilitation Evaluation System Medical Interaction Subscale [CARES-MIS]) were measured at baseline and monthly for 4 months. The primary outcome was change score for FACIT-Sp at 3 months. Secondary endpoints included change score for FACIT-Sp at 4 months and change scores for other scales at 3 and 4 months. This trial is registered with ClinicalTrials.gov, number NCT01248624. FINDINGS 461 patients completed baseline measures (228 intervention, 233 control); 393 completed at least one follow-up assessment. At 3-months, there was a non-significant difference in change score for FACIT-Sp between intervention and control groups (3·56 points [95% CI -0·27 to 7·40], p=0·07), a significant difference in QUAL-E (2·25 [0·01 to 4·49], p=0·05) and FAMCARE-P16 (3·79 [1·74 to 5·85], p=0·0003), and no difference in ESAS (-1·70 [-5·26 to 1·87], p=0·33) or CARES-MIS (-0·66 [-2·25 to 0·94], p=0·40). At 4 months, there were significant differences in change scores for all outcomes except CARES-MIS. All differences favoured the intervention group. INTERPRETATION Although the difference in quality of life was non-significant at the primary endpoint, this trial shows promising findings that support early palliative care for patients with advanced cancer.

CONTEXT Specialized palliative care teams are increasingly providing care for the terminally ill. However, the impact of such teams on quality of life, satisfaction with care, and economic cost has not been examined systematically using detailed criteria for study quality. OBJECTIVE To systematically review the evidence for effectiveness of specialized palliative care. DATA SOURCES We performed a keyword search of the following databases from their inception to January 2008: MEDLINE, Ovid Healthstar, CINAHL, EMBASE, and the Cochrane Central Register of Controlled Trials. STUDY SELECTION We included all randomized controlled trials in which specialized palliative care was the intervention and for which outcomes included quality of life, satisfaction with care, or economic cost. DATA EXTRACTION Data on population, intervention, outcome, methods, and methodological quality were extracted by 2 investigators using standardized criteria. RESULTS Of 396 reports of randomized controlled trials, 22 met our inclusion criteria. There was most consistent evidence for effectiveness of specialized palliative care in improvement of family satisfaction with care (7 of 10 studies favored the intervention). Only 4 of 13 studies assessing quality of life and 1 of 14 assessing symptoms showed a significant benefit of the intervention; however, most studies lacked statistical power to report conclusive results, and quality-of-life measures were not specific for terminally ill patients. There was evidence of significant cost savings of specialized palliative care in only 1 of the 7 studies that assessed this outcome. Methodological limitations were identified in all trials, including contamination of the control group, failure to account for clustering in cluster randomization studies, and substantial problems with recruitment, attrition, and adherence. CONCLUSIONS The evidence for benefit from specialized palliative care is sparse and limited by methodological shortcomings. Carefully planned trials, using a standardized palliative care intervention and measures constructed specifically for this population, are needed.

Purpose To provide evidence-based recommendations to oncology clinicians, patients, family and friend caregivers, and palliative care specialists to update the 2012 American Society of Clinical Oncology (ASCO) provisional clinical opinion (PCO) on the integration of palliative care into standard oncology care for all patients diagnosed with cancer. Methods ASCO convened an Expert Panel of members of the ASCO Ad Hoc Palliative Care Expert Panel to develop an update. The 2012 PCO was based on a review of a randomized controlled trial (RCT) by the National Cancer Institute Physicians Data Query and additional trials. The panel conducted an updated systematic review seeking randomized clinical trials, systematic reviews, and meta-analyses, as well as secondary analyses of RCTs in the 2012 PCO, published from March 2010 to January 2016. Results The guideline update reflects changes in evidence since the previous guideline. Nine RCTs, one quasiexperimental trial, and five secondary analyses from RCTs in the 2012 PCO on providing palliative care services to patients with cancer and/or their caregivers, including family caregivers, were found to inform the update. Recommendations Inpatients and outpatients with advanced cancer should receive dedicated palliative care services, early in the disease course, concurrent with active treatment. Referral of patients to interdisciplinary palliative care teams is optimal, and services may complement existing programs. Providers may refer family and friend caregivers of patients with early or advanced cancer to palliative care services.

PURPOSE Although there is increasing advocacy for timely symptom control in patients with cancer, few studies have assessed outpatient palliative care clinics. This study assessed prospectively the efficacy of an Oncology Palliative Care Clinic (OPCC) in improving patient symptom distress and satisfaction. PATIENTS AND METHODS Eligible patients were new referrals to an OPCC, had metastatic cancer, were at least 18 years old, and were well enough and able to speak and read English sufficiently to provide informed consent and complete questionnaires. Patients received a consultation by a palliative care team. The primary end points of symptom control and patient satisfaction were assessed using the Edmonton Symptom Assessment Scale (ESAS) and patient-adapted Family Satisfaction with Advanced Cancer Care (FAMCARE) scale at baseline, 1 week, and 1 month. Initial and follow-up scores were compared using paired t tests. RESULTS Of 150 patients enrolled, 123 completed 1-week assessments, and 88 completed 4-week assessments. At baseline, the mean ESAS Distress Score (EDS) was 39.5. The mean improvement in EDS was 8.8 points (P < .0001) at 1 week and 7.0 points (P < .0001) at 1 month. Statistically significant improvements were observed for pain, fatigue, nausea, depression, anxiety, drowsiness, appetite, dyspnea, insomnia, and constipation at 1 week (all P < or = .005) and 1 month (all P < or = .05). The mean improvement in FAMCARE score was 6.1 points (P < .0001) at 1 week and 5.0 points (P < .0001) at 1 month. CONCLUSION This phase II study demonstrates efficacy of an OPCC for improvement of symptom control and patient satisfaction with care. Randomized controlled trials are indicated to further evaluate the effectiveness of specialized outpatient palliative care.

Pathways to distress: The multiple determinants of depression, hopelessness, and the desire for hastened death in metastatic cancer patients

We tested a model in which psychosocial and disease-related variables act as multiple protective and risk factors for psychological distress in patients with metastatic cancer. We hypothesized that depression and hopelessness constitute common pathways of distress, which mediate the effects of psychosocial and disease-related factors on the desire for hastened death. This model was tested on a cross-sectional sample of 406 patients with metastatic gastrointestinal or lung cancer recruited at outpatient clinics of a Toronto cancer hospital, using structural equation modeling. The results supported the model. High disease burden, insecure attachment, low self-esteem, and younger age were risk factors for depression. Low spiritual well-being was a risk factor for hopelessness. Depression and hopelessness were found to be mutually reinforcing, but distinct constructs. Both depression and hopelessness independently predicted the desire for hastened death, and mediated the effects of psychosocial and disease-related variables on this outcome. The identified risk factors support a holistic approach to palliative care in patients with metastatic cancer, which attends to physical, psychological, and spiritual factors to prevent and treat distress in patients with advanced disease.

PURPOSE Although early intervention is increasingly advocated to prevent and relieve distress in patients with metastatic cancer, the risk factors for such symptoms and their trajectory are not well established. We therefore conducted a longitudinal study to determine the course and predictors of depressive symptoms. PATIENTS AND METHODS Patients (N = 365) with metastatic gastrointestinal or lung cancer completed measures of physical distress, self-esteem, attachment security, spiritual well-being, social support, hopelessness, and depression at baseline; physical distress, social support, hopelessness, and depression were subsequently assessed at 2-month intervals. RESULTS Of the sample, 35% reported at least mild depressive symptoms, with 16% reporting moderate to severe depressive symptoms that persisted in at least one third of such individuals. Moderate to severe depressive symptoms were almost three times more common in the final 3 months of life than > or = 1 year before death. Predictors of depressive symptoms included younger age, antidepressant use at baseline, lower self-esteem and spiritual well-being, and greater attachment anxiety, hopelessness, physical burden of illness, and proximity to death. The combination of greater physical suffering and psychosocial vulnerability put individuals at greatest risk for depression. CONCLUSION Depressive symptoms in advanced cancer patients are relatively common and may arise as a final common pathway of distress in response to psychosocial vulnerabilities, physical suffering, and proximity to death. These findings support the need for an integrated approach to address emotional and physical distress in this population and to determine whether early intervention may prevent depression at the end of life.

Importance The use of palliative care programs and the number of trials assessing their effectiveness have increased. Objective To determine the association of palliative care with quality of life (QOL), symptom burden, survival, and other outcomes for people with life-limiting illness and for their caregivers. Data Sources MEDLINE, EMBASE, CINAHL, and Cochrane CENTRAL to July 2016. Study Selection Randomized clinical trials of palliative care interventions in adults with life-limiting illness. Data Extraction and Synthesis Two reviewers independently extracted data. Narrative synthesis was conducted for all trials. Quality of life, symptom burden, and survival were analyzed using random-effects meta-analysis, with estimates of QOL translated to units of the Functional Assessment of Chronic Illness Therapy-palliative care scale (FACIT-Pal) instrument (range, 0-184 [worst-best]; minimal clinically important difference [MCID], 9 points); and symptom burden translated to the Edmonton Symptom Assessment Scale (ESAS) (range, 0-90 [best-worst]; MCID, 5.7 points). Main Outcomes and Measures Quality of life, symptom burden, survival, mood, advance care planning, site of death, health care satisfaction, resource utilization, and health care expenditures. Results Forty-three RCTs provided data on 12 731 patients (mean age, 67 years) and 2479 caregivers. Thirty-five trials used usual care as the control, and 14 took place in the ambulatory setting. In the meta-analysis, palliative care was associated with statistically and clinically significant improvements in patient QOL at the 1- to 3-month follow-up (standardized mean difference, 0.46; 95% CI, 0.08 to 0.83; FACIT-Pal mean difference, 11.36] and symptom burden at the 1- to 3-month follow-up (standardized mean difference, -0.66; 95% CI, -1.25 to -0.07; ESAS mean difference, -10.30). When analyses were limited to trials at low risk of bias (n = 5), the association between palliative care and QOL was attenuated but remained statistically significant (standardized mean difference, 0.20; 95% CI, 0.06 to 0.34; FACIT-Pal mean difference, 4.94), whereas the association with symptom burden was not statistically significant (standardized mean difference, -0.21; 95% CI, -0.42 to 0.00; ESAS mean difference, -3.28). There was no association between palliative care and survival (hazard ratio, 0.90; 95% CI, 0.69 to 1.17). Palliative care was associated consistently with improvements in advance care planning, patient and caregiver satisfaction, and lower health care utilization. Evidence of associations with other outcomes was mixed. Conclusions and Relevance In this meta-analysis, palliative care interventions were associated with improvements in patient QOL and symptom burden. Findings for caregiver outcomes were inconsistent. However, many associations were no longer significant when limited to trials at low risk of bias, and there was no significant association between palliative care and survival.

The nature of cancer control is changing, with an increasing emphasis, fuelled by public and political demand, on prevention, early diagnosis, and patient experience during and after treatment. At the same time, primary care is increasingly promoted, by governments and health funders worldwide, as the preferred setting for most health care for reasons of increasing need, to stabilise health-care costs, and to accommodate patient preference for care close to home. It is timely, then, to consider how this expanding role for primary care can work for cancer control, which has long been dominated by highly technical interventions centred on treatment, and in which the contribution of primary care has been largely perceived as marginal. In this Commission, expert opinion from primary care and public health professionals with academic and clinical cancer expertise—from epidemiologists, psychologists, policy makers, and cancer specialists—has contributed to a detailed consideration of the evidence for cancer control provided in primary care and community care settings. Ranging from primary prevention to end-of-life care, the scope for new models of care is explored, and the actions needed to effect change are outlined. The strengths of primary care—its continuous, coordinated, and comprehensive care for individuals and families—are particularly evident in prevention and diagnosis, in shared follow-up and survivorship care, and in end-of-life care. A strong theme of integration of care runs throughout, and its elements (clinical, vertical, and functional) and the tools needed for integrated working are described in detail. All of this change, as it evolves, will need to be underpinned by new research and by continuing and shared multiprofessional development.

PURPOSE To describe current referral practices of oncologists to specialized palliative care (SPC) and define demographic characteristics, practice situations, and opinions associated with referral. METHODS Physician members of the Canadian Association of Medical Oncologists, Canadian Association of Radiation Oncologists, and Canadian Society of Surgical Oncology were invited to participate in an anonymous survey assessing SPC referral practices. Participants received two e-mailed and two mailed invitations. RESULTS The response rate was 72% (603 of 839 physicians); 37% were medical oncologists/hematologists, 50% were radiation oncologists, and 12% were surgical oncologists. Ninety-four percent reported that SPC was available to them, but only 37% reported that these services accepted patients on chemotherapy. Eighty-four percent referred terminally ill patients usually/always, but generally for uncontrolled symptoms or discharge planning late in the disease course. One third would refer to SPC earlier if it was renamed supportive care. Predictors of higher referral frequency included comprehensiveness of available SPC services (P = .004), satisfaction with SPC availability (P < .001), SPC acceptance of patients receiving chemotherapy (P < .001), and oncologist ease with referring patients to a palliative care service before they were close to death (P < .001). Controlling for specialty, predictors of referral at diagnosis or during chemotherapy, rather than later, included satisfaction with SPC service availability (P < .001) and SPC service acceptance of patients on chemotherapy (P < .001). CONCLUSION Oncologists referred patients frequently to SPC, but generally late in the disease course for patients with uncontrolled symptoms. Availability of comprehensive SPC, especially for patients receiving chemotherapy, and persisting definitional issues seem to be the main barriers preventing timely referral.

The Quality of Dying and Death

Sarah Hales; Camilla Zimmermann; Gary Rodin

During the past decade, research has examined definitions and conceptualizations of quality of dying and death in different populations. At the same time, there has been a call to clarify the distinctions between quality of dying and death and other end-of-life constructs. The purposes of this article are to (1) review research that examined definitions and conceptualizations of the quality of dying and death, (2) clarify the quality of dying and death construct and its distinction from quality of life and quality of care at the end of life, and (3) outline challenges that remain for health care professionals, researchers, and policy makers. Review of the literature revealed that the quality of dying and death construct is multidimensional, with 7 broad domains: physical experience, psychological experience, social experience, spiritual or existential experience, the nature of health care, life closure and death preparation, and the circumstances of death. The quality of dying and death is subjectively determined with numerous factors that influence its judgment, including culture, type and stage of disease, and social and professional role in the dying experience. Quality of dying and death is broader in scope than either quality of life at the end of life or quality of care at the end of life, although there is overlap among these constructs.
