ESMO Designated Centres of Integrated Oncology and Palliative Care (ESMO DCs): education, research and programme development survey

BACKGROUND

The European Society for Medical Oncology (ESMO) Designated Centres (DCs) of Integrated Oncology and Palliative Care is an incentive programme established in 2003 aiming to improve the integration of oncology and palliative care services provided by oncologists and oncology centres worldwide. Currently, the ESMO DCs programme has over 250 centres accredited from 54 countries worldwide, in all six world regions.

MATERIALS AND METHODS

To evaluate how ESMO can support centres to improve programme development, education and research and vice versa what each single centre can do to improve in these areas, we developed a survey which was shared with all active centres. Two hundred and seven ESMO DCs representing 44 countries were invited to participate. We used content analysis to identify response categories using a stepwise approach. After reviewing and coding all responses to each question separately, they were placed into categories, counted and labelled.

RESULTS

Of the 207 centres that were invited to participate, 146 centres started the survey, representing 43 countries. Five overarching topics were identified. They included (i) joint events and educational activities; (ii) sharing of materials and defining common standards; (iii) sharing of experiences, scientific knowledge and expertise; (iv) research collaboration; and (v) ESMO support. Respondents were willing to support the ESMO DC community group in all topics and were also asking ESMO to support their centres in these issues in the future.

CONCLUSION

The study showed that the ESMO DCs are willing to provide support to improve education, research and programme development. They are also eager to contribute and collaborate amongst each other, but also request ESMO to offer advice and help to improve these issues in the DCs. In the future, facilitation of joint research projects and development of arenas to share experiences, educational and programme developments, and other resources are to be explored and could be offered to the DCs worldwide.

Elderly gynaecological cancer patients at risk for poor end of life care: a population-based study from the Swedish Register of Palliative Care

Introduction: Poorer end-of-life (EOL) care for elderly cancer patients has been reported. We assessed the impact of age on 13 indicators for the quality of EOL care as well as adherence to 6 national quality indicators in gynaecological cancer patients.Methods: Age-dependent differences in 13 palliative care quality indicators were studied in gynaecological cancer patients registered in the population-based Swedish Register of Palliative Care. Association between the patient's age and each quality indicator was analyzed by logistic regression, adjusted for place of death where appropriate. Adherence to six national quality indicators determined by the Swedish National Board of Health and Welfare was estimated in all patients.Results: We included 3940 patients with the following age distribution: 1.6% were 18-39 years of age, 12.3% 40-59 years, 37.2% 60-74 years, 28.9% 75-84 years and 20% were ≥85 years. Age-dependent differences in implementation rate were present for some of the 13 quality indicators. Compared to elderly cancer patients, younger patients were more likely to be cared for by a specialized palliative care service, more often informed about imminent death as well as assessed for pain. For most national quality indicators, the goal level was not met. Only for the 'on demand prescription for pain', the goal level was reached.Conclusions: EOL care did not meet national quality indicators in this population-based data from Sweden, in particular in the elderly population. Elderly gynaecological cancer patients are at high risk of poorer EOL care without the involvement of specialized palliative care services. Palliative care services need to be implemented across all institutions of EOL care to ensure good and equal care.

The rare Arg181Cys mutation in the μ opioid receptor can abolish opioid responses

BACKGROUND

Genetic variability contributes to variable clinical response to opioids. This study emerged from the observation of three Norwegian patients who showed no or extraordinary poor response to very high doses of opioids. We suspected a genetic defect and applied a 'most likely candidate gene' approach to investigate this possibility.

METHODS

DNA sequencing was used to search for mutations in coding regions of the OPRM1 gene, encoding the μ opioid receptor (hMOR), in one patient. The remaining two patients, and two cohorts comprising 2158 European cancer pain patients and 600 Norwegian healthy volunteers, respectively, were genotyped using a custom-made TaqMan SNP allelic discrimination assay.

RESULTS

DNA sequencing disclosed a homozygous, inactivating Arg181Cys mutation in hMOR in the patient who showed no effects from opioids. The two patients with poor effect from very high doses of opioids were both heterozygous for the mutation. Six heterozygous patients identified among the European cancer patients all used high doses of opioids and/or reported inferior effect on their pain. About one in every 100 Norwegians is heterozygous for the mutation.

CONCLUSIONS

The Arg181Cys mutation occurs at clinically relevant frequencies and produces a signaling dead hMOR which may abolish or significantly reduce opioid effects in affected individuals. Anesthesiologists and practitioners in pain medicine should be aware of this mutation as a possible explanation for inefficiency of opioids and consider genotyping in relevant cases. Individuals homozygous for the mutation may need a highly personalized approach to pain therapy.

Characteristics of the case mix, organisation and delivery in cancer palliative care: a challenge for good-quality research

OBJECTIVES

Palliative care (PC) services and patients differ across countries. Data on PC delivery paired with medical and self-reported data are seldom reported. Aims were to describe (1) PC organisation and services in participating centres and (2) characteristics of patients in PC programmes.

METHODS

This was an international prospective multicentre study with a single web-based survey on PC organisation, services and academics and patients' self-reported symptoms collected at baseline and monthly thereafter, with concurrent registrations of medical data by healthcare providers. Participants were patients ≥18 enrolled in a PC programme.

RESULTS

30 centres in 12 countries participated; 24 hospitals, 4 hospices, 1 nursing home, 1 home-care service. 22 centres (73%) had PC in-house teams and inpatient and outpatient services. 20 centres (67%) had integral chemotherapy/radiotherapy services, and most (28/30) had access to general medical or oncology inpatient units. Physicians or nurses were present 24 hours/7 days in 50% and 60% of centres, respectively. 50 centres (50%) had professorships, and 12 centres (40%) had full-time/part-time research staff. Data were available on 1698 patients: 50% females; median age 66 (range 21-97); median Karnofsky score 70 (10-100); 1409 patients (83%) had metastatic/disseminated disease; tiredness and pain in the past 24 hours were most prominent. During follow-up, 1060 patients (62%) died; 450 (44%) <3 months from inclusion and 701 (68%) within 6 months. ANOVA and χ² tests showed that hospice/nursing home patients were significantly older, had poorer performance status and had shorter survival compared with hospital-patients (p<.0.001).

CONCLUSIONS

There is a wide variation in PC services and patients across Europe. Detailed characterisation is the first step in improving PC services and research.

Are strong opioids equally effective and safe in the treatment of chronic cancer pain? A multicenter randomized phase IV 'real life' trial on the variability of response to opioids

BACKGROUND

Guidelines tend to consider morphine and morphine-like opioids comparable and interchangeable in the treatment of chronic cancer pain, but individual responses can vary. This study compared the analgesic efficacy, changes of therapy and safety profile over time of four strong opioids given for cancer pain.

PATIENT AND METHODS

In this four-arm multicenter, randomized, comparative, of superiority, phase IV trial, oncological patients with moderate to severe pain requiring WHO step III opioids were randomly assigned to receive oral morphine or oxycodone or transdermal fentanyl or buprenorphine for 28 days. At each visit, pain intensity, modifications of therapy and adverse drug reactions (ADRs) were recorded. The primary efficacy end point was the proportion of nonresponders, meaning patients with worse or unchanged average pain intensity (API) between the first and last visit, measured on a 0-10 numerical rating scale. (NCT01809106).

RESULTS

Forty-four centers participated in the trial and recruited 520 patients. Worst pain intensity and API decreased over 4 weeks with no significant differences between drugs. Nonresponders ranged from 11.5% (morphine) to 14.4% (buprenorphine). Appreciable changes were made in the treatment schedules over time. Each group required increases in the daily dose, from 32.7% (morphine) to 121.2% (transdermal fentanyl). Patients requiring adjuvant analgesics ranged from 68.9% (morphine) to 81.6% (oxycodone), switches varied from 22.1% (morphine) to 12% (oxycodone), discontinuation of treatment from 27% ( morphine) to 14.5% (fentanyl). ADRs were similar except for effects on the nervous system, which significantly prevailed with morphine.

CONCLUSION

The main findings were the similarity in pain control, response rates and main adverse reactions among opioids. Changes in therapy schedules were notable over time. A considerable proportion of patients were nonresponders or poor responders.

Does chemotherapy improve health-related quality of life in advanced pancreatic cancer? A systematic review

Chemotherapy is increasingly being used in advanced pancreatic cancer, but side-effects are common. The aim of this systematic review was to assess whether chemotherapy improves health-related quality of life (HRQoL), pain or cachexia. Thirty studies were reviewed. Four of 23 studies evaluating HRQoL, 7 of 24 studies evaluating pain and 0 of 8 studies evaluating cachexia found differences between treatment arms. Change in HRQoL from baseline was evaluated in 14 studies: five studies reported an improvement in at least one treatment arm; three a worsening and the remaining stable scores. Change in pain intensity from baseline was evaluated in eight studies, and improvement was observed in seven. Of the four studies reporting improved survival, three reported improved HRQoL or pain. In conclusion, chemotherapy can stabilize HRQoL and improve pain control. Effects on cachexia are hard to elucidate. Improved survival does not come at the expense of HRQoL or pain control.

The effect of real-time electronic monitoring of patient-reported symptoms and clinical syndromes in outpatient workflow of medical oncologists: E-MOSAIC, a multicenter cluster-randomized phase III study (SAKK 95/06)

BACKGROUND

Patients with advanced, incurable cancer receiving anticancer treatment often experience multidimensional symptoms. We hypothesize that real-time monitoring of both symptoms and clinical syndromes will improve symptom management by oncologists and patient outcomes.

PATIENTS AND METHODS

In this prospective multicenter cluster-randomized phase-III trial, patients with incurable, symptomatic, solid tumors, who received new outpatient chemotherapy with palliative intention, were eligible. Immediately before the weekly oncologists' visit, patients completed the palm-based E-MOSAIC assessment (Edmonton-Symptom-Assessment-Scale, ≤3 additional symptoms, estimated nutritional intake, body weight change, Karnofsky Performance Status, medications for pain, fatigue, nutrition). A cumulative, longitudinal monitoring sheet (LoMoS) was printed immediately. Eligible experienced oncologists were defined as one cluster each and randomized to receive the immediate print-out LoMoS (intervention) or not (control). Primary analysis limited to patients having uninterrupted (>4/6 visits with same oncologist) patient-oncologist sequences was a mixed model for the difference in patients global quality of life (G-QoL; items 29/30 of EORTC-QlQ-c30) between baseline (BL) and week 6. Intention-to-treat (ITT) analysis included all eligible patients.

RESULTS

In 8 centers, 82 oncologists treated 264 patients (median 66 years; overall survival intervention 6.3, control 5.4 months) with various tumors. The between-arm difference in G-QoL of 102 uninterrupted patients (intervention: 55; control: 47) was 6.8 (P = 0.11) in favor of the intervention; in a sensitivity analysis (oncologists treating ≥2 patients; 50, 39), it was 9.0 (P = 0.07). ITT analysis revealed improvement in symptoms (difference last study visit-BL: intervention -5.4 versus control 2.1, P = 0.003) and favored the intervention for communication and coping. More patients with high symptom load received immediate symptom management (chart review, nurse-patient interview) by oncologists getting the LoMoS.

CONCLUSION

Monitoring of patient symptoms, clinical syndromes and their management clearly reduced patients' symptoms, but not QoL. Our results encourage the implementation of real-time monitoring in the routine workflow of oncologist with a computer solution.

Renal function and symptoms/adverse effects in opioid-treated patients with cancer

BACKGROUND

Renal impairment and the risk of toxicity caused by accumulation of opioids and/or active metabolites is an under-investigated issue. This study aimed at analysing if symptoms/adverse effects in opioid-treated patients with cancer were associated with renal function.

METHODS

Cross-sectional multicentre study (European Pharmacogenetic Opioid Study, 2005-2008), in which 1147 adult patients treated exclusively with only one of the most frequently reported opioids (morphine/oxycodone/fentanyl) for at least 3 days were analysed. Fatigue, nausea/vomiting, pain, loss of appetite, constipation and cognitive dysfunction were assessed (EORTC QLQ-C30). Glomerular filtration rate (GFR) was estimated using Cockcroft-Gault (CG), Modification of Diet in Renal Disease (MDRD), and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI Creatinine) equations.

RESULTS

Mild to severe low GFR was observed among 40-54% of patients. CG equation showed that patients with mild and moderate/severe low GFR on morphine treatment had higher odds of having severe constipation (P < 0.01) than patients with normal GFR. In addition, patients with moderate/severe low GFR on morphine treatment were more likely to have loss of appetite (P = 0.04). No other significant associations were found.

CONCLUSION

Only severe constipation and loss of appetite were associated with low GFR in patients treated with morphine. Oxycodone and fentanyl, in relation to the symptoms studied, seem to be safe as used and titrated in routine cancer pain care.

Indicators of integration of oncology and palliative care programs: an international consensus

BACKGROUND

Recently, the concept of integrating oncology and palliative care has gained wide professional and scientific support; however, a global consensus on what constitutes integration is unavailable. We conducted a Delphi Survey to develop a consensus list of indicators on integration of specialty palliative care and oncology programs for advanced cancer patients in hospitals with ≥100 beds.

METHODS

International experts on integration rated a list of indicators on integration over three iterative rounds under five categories: clinical structure, processes, outcomes, education, and research. Consensus was defined a priori by an agreement of ≥70%. Major criteria (i.e. most relevant and important indicators) were subsequently identified.

RESULTS

Among 47 experts surveyed, 46 (98%), 45 (96%), and 45 (96%) responded over the three rounds. Nineteen (40%) were female, 24 (51%) were from North America, and 14 (30%) were from Europe. Sixteen (34%), 7 (15%), and 25 (53%) practiced palliative care, oncology, and both specialties, respectively. After three rounds of deliberation, the panelists reached consensus on 13 major and 30 minor indicators. Major indicators included two related to structure (consensus 95%-98%), four on processes (88%-98%), three on outcomes (88%-91%), and four on education (93%-100%). The major indicators were considered to be clearly stated (9.8/10), objective (9.4/10), amenable to accurate coding (9.5/10), and applicable to their own countries (9.4/10).

CONCLUSIONS

Our international experts reached broad consensus on a list of indicators of integration, which may be used to identify centers with a high level of integration, and facilitate benchmarking, quality improvement, and research.

Validation of the Consensus-Definition for Cancer Cachexia and evaluation of a classification model--a study based on data from an international multicentre project (EPCRC-CSA)

BACKGROUND

Weight loss limits cancer therapy, quality of life and survival. Common diagnostic criteria and a framework for a classification system for cancer cachexia were recently agreed upon by international consensus. Specific assessment domains (stores, intake, catabolism and function) were proposed. The aim of this study is to validate this diagnostic criteria (two groups: model 1) and examine a four-group (model 2) classification system regarding these domains as well as survival.

PATIENTS AND METHODS

Data from an international patient sample with advanced cancer (N = 1070) were analysed. In model 1, the diagnostic criteria for cancer cachexia [weight loss/body mass index (BMI)] were used. Model 2 classified patients into four groups 0-III, according to weight loss/BMI as a framework for cachexia stages. The cachexia domains, survival and sociodemographic/medical variables were compared across models.

RESULTS

Eight hundred and sixty-one patients were included. Model 1 consisted of 399 cachectic and 462 non-cachectic patients. Cachectic patients had significantly higher levels of inflammation, lower nutritional intake and performance status and shorter survival. In model 2, differences were not consistent; appetite loss did not differ between group III and IV, and performance status not between group 0 and I. Survival was shorter in group II and III compared with other groups. By adding other cachexia domains to the model, survival differences were demonstrated.

CONCLUSION

The diagnostic criteria based on weight loss and BMI distinguish between cachectic and non-cachectic patients concerning all domains (intake, catabolism and function) and is associated with survival. In order to guide cachexia treatment a four-group classification model needs additional domains to discriminate between cachexia stages.

A pilot study of nasal fentanyl for patient controlled treatment of cancer pain

BACKGROUND

Slow release (SR) opioids around the clock are the mainstay for moderate to strong cancer pain. This recommendation is not scientifically based. Therefore, a phase 1 pilot study of rapid acting nasal fentanyl (NF) taken on demand as the only opioid for cancer pain to explore feasibility and safety aspects was launched.

METHODS

Patients with cancer, naïve to strong opioids but in need of such drugs, were included. They received a test dose of NF before titration (1-5 days) was started. Ten days treatment was followed by 7 days of observation after switching to SR morphine. Pain relief, nausea, sedation, and local irritation were assessed (11-point numeric rating scale [NRS]). Other adverse events (AEs) were also recorded by the patient. Investigator had regular patient telephone contact.

RESULTS

Ten patients were included. The test dose was well tolerated. Venous fentanyl concentrations at 11 minutes after the test dose differed considerably. All subjects completed the titration; six patients the treatment phase. Three serious AEs were reported; all due to hospitalization, none related to NF. A possible adverse drug reaction (hearing abnormalities) was reported. Other adverse effects were minor. NF treatment reduced average pain for the whole group compared to baseline (4.6-3.7 on the 11-point NRS) and pain relief was achieved in 187/230 (81 percent) of NF administrations (reduction of 2 or more on the 11-point NRS 15 minutes after NF administration).

CONCLUSION

This explorative study suggests that it is reasonable that the concept of treating pain in patients with cancer using NF on demand can undergo controlled clinical studies.

Is there a genetic cause for cancer cachexia? - a clinical validation study in 1797 patients

BACKGROUND

Cachexia has major impact on cancer patients' morbidity and mortality. Future development of cachexia treatment needs methods for early identification of patients at risk. The aim of the study was to validate nine single-nucleotide polymorphisms (SNPs) previously associated with cachexia, and to explore 182 other candidate SNPs with the potential to be involved in the pathophysiology.

METHOD

A total of 1797 cancer patients, classified as either having severe cachexia, mild cachexia or no cachexia, were genotyped.

RESULTS

After allowing for multiple testing, there was no statistically significant association between any of the SNPs analysed and the cachexia groups. However, consistent with prior reports, two SNPs from the acylpeptide hydrolase (APEH) gene showed suggestive statistical significance (P=0.02; OR, 0.78).

CONCLUSION

This study failed to detect any significant association between any of the SNPs analysed and cachexia; although two SNPs from the APEH gene had a trend towards significance. The APEH gene encodes the enzyme APEH, postulated to be important in the endpoint of the ubiquitin system and thus the breakdown of proteins into free amino acids. In cachexia, there is an extensive breakdown of muscle proteins and an increase in the production of acute phase proteins in the liver.

How to switch from morphine or oxycodone to methadone in cancer patients? a randomised clinical phase II trial

AIM

Opioid switching is a treatment strategy in cancer patients with unacceptable pain and/or adverse effects (AEs). We investigated whether patients switched to methadone by the stop and go (SAG) strategy have lower pain intensity (PI) than the patients switched over three days (3DS), and whether the SAG strategy is as safe as the 3DS strategy.

METHODS

In this prospective, open, parallel-group, multicentre study, 42 cancer patients on morphine or oxycodone were randomised to the SAG or 3DS switching-strategy to methadone. The methadone dose was calculated using a dose-dependent ratio. PI, AEs and serious adverse events (SAEs) were recorded daily for 14 days. Primary outcome was average PI day 3. Secondary outcomes were PI now and AEs day 3 and 14 and number of SAEs.

RESULTS

Twenty one patients were randomised to each group, 16 (SAG) and 19 (3DS) patients received methadone. The mean preswitch morphine doses were 900 mg/day in SAG and 1330 mg/day in 3DS. No differences between groups were found in mean average PI day 3 (mean difference 0.5 (CI -1.2-2.2); SAG 4.1 (CI 2.3-5.9) and 3DS 3.6 (CI 2.9-4.3) or in PI now. The SAG group had more dropouts and three SAEs (two deaths and one severe sedation). No SAEs were observed in the 3DS group.

CONCLUSION

The SAG patients reported a trend of more pain, had significantly more dropouts and three SAEs, which indicate that the SAG strategy should not replace the 3DS when switching from high doses of morphine or oxycodone to methadone.

Content development for EUROPEAN GUIDELINES on the use of opioids for cancer pain: a systematic review and Expert Consensus Study

Workpackage 3.1 (WP 3.1), within the European Palliative Research Collaborative (EPCRC), was aimed at critically revising and updating the European Association for Palliative Care recommendations on cancer pain management. The aim of this paper is to report the results of the first phase in the revision process which consists of a literature review and an expert consensus about the contents to be considered relevant in the development of the new guidelines. A systematic literature search was carried out from 2001 to 2008 through various databases including Medline, Cinahl, Cochrane Database of Systematic Reviews, Embase and Google. Through this process, guideline quality was evaluated, content was compared with EAPC recommendations and a first set of key-points was developed. A modified two-round Delphi method was applied to choose the most relevant topics for future systematic literature reviews. Fourteen guidelines on cancer pain management, published or updated after 2000, were retrieved. A comparison of these guidelines with the EAPC recommendations led to the formulation of 37 key-points, which were submitted to a panel of experts through a Delphi method. Through the responses given by the experts (25 after the first round and 19 after the second) and after a revision by the WP 3.1 local and steering committees, a final list of 22 topics was generated to answer all identified key-points. Each of these topics will be the object of systematic literature reviews. The final version of the "Evidence-based guidelines for the use of opioid analgesics in the treatment of cancer pain: the EAPC recommendations" will be based on the results of the 22 systematic literature reviews.

Patients with problematic opioid use can be weaned from codeine without pain escalation

BACKGROUND

Brief treatments for chronic non-malignant pain patients with problematic opioid use are warranted. The aims of the present study were to investigate (1) whether it is possible to withdraw codeine use in such patients with a brief cognitive-behavioural therapy (CBT), (2) whether this could be done without pain escalation and reduction in quality of life and (3) to explore the effects of codeine reduction on neurocognitive functioning.

METHODS

Eleven patients using codeine daily corresponding to 40-100 mg morphine were included. Two specifically trained physicians treated the patients with six CBT sessions, tapering codeine gradually within 8 weeks. Codeine use, pain intensity, quality of life and neuropsychological functioning were assessed at pre-treatment to the 3-month follow-up.

RESULTS

Codeine use was significantly reduced from mean 237 mg [standard deviation (SD) 65] pre-treatment to 45 mg (SD 66) post-treatment and to 48 mg (SD 65) at follow-up without significant pain escalation or reductions in quality of life. Moreover, neuropsychological functioning improved significantly on some tests, while others remained unchanged.

CONCLUSION

The promising findings of codeine reduction in this weaning therapy programme for pain patients with problematic opioid use should be further evaluated in a larger randomized control trial comparing this brief CBT with both another brief treatment and attention placebo condition.

Deaths of children occurring at home in six European countries

OBJECTIVES

Until now there have been no population-based European data available regarding place of death of children. This study aimed to compare proportions of home death for all children and for children dying from complex chronic conditions (CCC) in six European countries and to investigate related socio-demographic and clinical factors.

METHODS

Data were collected from the death certificates of all deceased children aged 1-17 years in Belgium, the Netherlands, Norway, England, Wales (2003) and Italy (2002). Gender, cause and place of death (home vs. outside home) and socio-demographic factors (socio-economic status, degree of urbanization and number of hospital beds in the area) were included in the analyses. Data were analysed using frequencies and multivariate logistic regression.

RESULTS

In total 3328 deaths were included in the analyses; 1037 (31.2%) related to CCC. The proportion of home deaths varied between 19.6% in Italy and 28.6% in the Netherlands and was higher for children dying from CCC in all the countries studied, varying between 21.7% in Italy and 50% in the Netherlands. Among children dying from CCC, home death was more likely for cancer patients and those aged over 10 years. After controlling for potentially related clinical and socio-demographic factors, differences in the proportion of home deaths between countries remained significant, with higher proportions in Belgium and the Netherlands as compared with Italy.

CONCLUSIONS

Although home deaths comprise a substantial proportion of all deaths of children with CCCs, variation among disease categories and across countries suggest that considerable potential still exists for further improvements in facilitating end-of-life care in the home for those children and families who desire to be in this location.
