Double-Blind, Placebo-Controlled Study of Quality of Life, Hematologic End Points, and Safety of Weekly Epoetin Alfa in Children With Cancer Receiving Myelosuppressive Chemotherapy

A Dutch paediatric palliative care guideline: a systematic review and evidence-based recommendations for symptom treatment

BACKGROUND

Children with life-threatening and life-limiting conditions can experience high levels of suffering due to multiple distressing symptoms that result in poor quality of life and increase risk of long-term distress in their family members. High quality symptom treatment is needed for all these children and their families, even more so at the end-of-life. In this paper, we provide evidence-based recommendations for symptom treatment in paediatric palliative patients to optimize care.

METHODS

A multidisciplinary panel of 56 experts in paediatric palliative care and nine (bereaved) parents was established to develop recommendations on symptom treatment in paediatric palliative care including anxiety and depression, delirium, dyspnoea, haematological symptoms, coughing, skin complaints, nausea and vomiting, neurological symptoms, pain, death rattle, fatigue, paediatric palliative sedation and forgoing hydration and nutrition. Recommendations were based on evidence from a systematic literature search, additional literature sources (such as guidelines), clinical expertise, and patient and family values. We used the GRADE methodology for appraisal of evidence. Parents were included in the guideline panel to ensure the representation of patient and family values.

RESULTS

We included a total of 18 studies that reported on the effects of specific (non) pharmacological interventions to treat symptoms in paediatric palliative care. A few of these interventions showed significant improvement in symptom relief. This evidence could only (partly) answer eight out of 27 clinical questions. We included 29 guidelines and two textbooks as additional literature to deal with lack of evidence. In total, we formulated 221 recommendations on symptom treatment in paediatric palliative care based on evidence, additional literature, clinical expertise, and patient and family values.

CONCLUSION

Even though available evidence on symptom-related paediatric palliative care interventions has increased, there still is a paucity of evidence in paediatric palliative care. We urge for international multidisciplinary multi-institutional collaboration to perform high-quality research and contribute to the optimization of symptom relief in palliative care for all children worldwide.

Palliative care for children: methodology for the development of a national clinical practice guideline

BACKGROUND

Provision of paediatric palliative care for children with life-threatening or life-limiting conditions and their families is often complex. Guidelines can support professionals to deliver high quality care. Stakeholders expressed the need to update the first Dutch paediatric palliative care guideline with new scientific literature and new topics. This paper provides an overview of the methodology that is used for the revision of the Dutch paediatric palliative care guideline and a brief presentation of the identified evidence.

METHODS

The revised paediatric palliative care guideline was developed with a multidisciplinary guideline panel of 72 experts in paediatric palliative care and nine (bereaved) parents of children with life-threatening or life-limiting conditions. The guideline covered multiple topics related to (refractory) symptom treatment, advance care planning and shared-decision making, organisation of care, psychosocial care, and loss and bereavement. We established six main working groups that formulated 38 clinical questions for which we identified evidence by updating two existing systematic literature searches. The GRADE (CERQual) methodology was used for appraisal of evidence. Furthermore, we searched for additional literature such as existing guidelines and textbooks to deal with lack of evidence.

RESULTS

The two systematic literature searches yielded a total of 29 RCTs or systematic reviews of RCTs on paediatric palliative care interventions and 22 qualitative studies on barriers and facilitators of advance care planning and shared decision-making. We identified evidence for 14 out of 38 clinical questions. Furthermore, we were able to select additional literature (29 guidelines, two textbooks, and 10 systematic reviews) to deal with lack of evidence.

CONCLUSIONS

The revised Dutch paediatric palliative care guideline addresses many topics. However, there is limited evidence to base recommendations upon. Our methodology will combine the existing evidence in scientific literature, additional literature, expert knowledge, and perspectives of patients and their families to provide recommendations.

Review of acute kidney injury and progression to chronic kidney disease in pediatric patients undergoing hematopoietic cell transplant

While acute kidney injury (AKI) after hematopoietic cell transplant (HCT) has been well-described in pediatric patients, literature regarding the long term renal consequences of HCT-related AKI, the development of chronic kidney disease (CKD), and CKD care in pediatric patients post-HCT is limited. CKD affects almost 50% of patients after HCT with multifactorial etiology including infection, nephrotoxic medications, transplant-associated thrombotic microangiopathy, graft-versus-host disease, and sinusoidal obstruction syndrome. As renal function declines in CKD, eventually progressing to end stage kidney disease (ESKD), mortality increases and is more than 80% among patients requiring dialysis. Using society guidelines and current literature, this review summarizes definitions and etiologies of and management strategies among patients with AKI and CKD post-HCT with an emphasis on albuminuria, hypertension, nutrition, metabolic acidosis, anemia, and mineral bone disease. The goal of this review is to aid early identification and intervention in patients with renal dysfunction prior to development of ESKD, and to discuss ESKD and renal transplant in these patients post-HCT.

Intravenous iron versus oral iron versus no iron with or without erythropoiesis- stimulating agents (ESA) for cancer patients with anaemia: a systematic review and network meta-analysis

BACKGROUND

Anaemia is common among cancer patients and they may require red blood cell transfusions. Erythropoiesis-stimulating agents (ESAs) and iron might help in reducing the need for red blood cell transfusions. However, it remains unclear whether the combination of both drugs is preferable compared to using one drug.

OBJECTIVES

To systematically review the effect of intravenous iron, oral iron or no iron in combination with or without ESAs to prevent or alleviate anaemia in cancer patients and to generate treatment rankings using network meta-analyses (NMAs).

SEARCH METHODS

We identified studies by searching bibliographic databases (CENTRAL, MEDLINE, Embase; until June 2021). We also searched various registries, conference proceedings and reference lists of identified trials.

SELECTION CRITERIA

We included randomised controlled trials comparing intravenous, oral or no iron, with or without ESAs for the prevention or alleviation of anaemia resulting from chemotherapy, radiotherapy, combination therapy or the underlying malignancy in cancer patients.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed risk of bias. Outcomes were on-study mortality, number of patients receiving red blood cell transfusions, number of red blood cell units, haematological response, overall mortality and adverse events. We conducted NMAs and generated treatment rankings. We assessed the certainty of the evidence using GRADE.

MAIN RESULTS

Ninety-six trials (25,157 participants) fulfilled our inclusion criteria; 62 trials (24,603 participants) could be considered in the NMA (12 different treatment options). Here we present the comparisons of ESA with or without iron and iron alone versus no treatment. Further results and subgroup analyses are described in the full text. On-study mortality We estimated that 92 of 1000 participants without treatment for anaemia died up to 30 days after the active study period. Evidence from NMA (55 trials; 15,074 participants) suggests that treatment with ESA and intravenous iron (12 of 1000; risk ratio (RR) 0.13, 95% confidence interval (CI) 0.01 to 2.29; low certainty) or oral iron (34 of 1000; RR 0.37, 95% CI 0.01 to 27.38; low certainty) may decrease or increase and ESA alone (103 of 1000; RR 1.12, 95% CI 0.92 to 1.35; moderate certainty) probably slightly increases on-study mortality. Additionally, treatment with intravenous iron alone (271 of 1000; RR 2.95, 95% CI 0.71 to 12.34; low certainty) may increase and oral iron alone (24 of 1000; RR 0.26, 95% CI 0.00 to 19.73; low certainty) may increase or decrease on-study mortality. Haematological response We estimated that 90 of 1000 participants without treatment for anaemia had a haematological response. Evidence from NMA (31 trials; 6985 participants) suggests that treatment with ESA and intravenous iron (604 of 1000; RR 6.71, 95% CI 4.93 to 9.14; moderate certainty), ESA and oral iron (527 of 1000; RR 5.85, 95% CI 4.06 to 8.42; moderate certainty), and ESA alone (467 of 1000; RR 5.19, 95% CI 4.02 to 6.71; moderate certainty) probably increases haematological response. Additionally, treatment with oral iron alone may increase haematological response (153 of 1000; RR 1.70, 95% CI 0.69 to 4.20; low certainty). Red blood cell transfusions We estimated that 360 of 1000 participants without treatment for anaemia needed at least one transfusion. Evidence from NMA (69 trials; 18,684 participants) suggests that treatment with ESA and intravenous iron (158 of 1000; RR 0.44, 95% CI 0.31 to 0.63; moderate certainty), ESA and oral iron (144 of 1000; RR 0.40, 95% CI 0.24 to 0.66; moderate certainty) and ESA alone (212 of 1000; RR 0.59, 95% CI 0.51 to 0.69; moderate certainty) probably decreases the need for transfusions. Additionally, treatment with intravenous iron alone (268 of 1000; RR 0.74, 95% CI 0.43 to 1.28; low certainty) and with oral iron alone (333 of 1000; RR 0.92, 95% CI 0.54 to 1.57; low certainty) may decrease or increase the need for transfusions. Overall mortality We estimated that 347 of 1000 participants without treatment for anaemia died overall. Low-certainty evidence from NMA (71 trials; 21,576 participants) suggests that treatment with ESA and intravenous iron (507 of 1000; RR 1.46, 95% CI 0.87 to 2.43) or oral iron (482 of 1000; RR 1.39, 95% CI 0.60 to 3.22) and intravenous iron alone (521 of 1000; RR 1.50, 95% CI 0.63 to 3.56) or oral iron alone (534 of 1000; RR 1.54, 95% CI 0.66 to 3.56) may decrease or increase overall mortality. Treatment with ESA alone may lead to little or no difference in overall mortality (357 of 1000; RR 1.03, 95% CI 0.97 to 1.10; low certainty). Thromboembolic events We estimated that 36 of 1000 participants without treatment for anaemia developed thromboembolic events. Evidence from NMA (50 trials; 15,408 participants) suggests that treatment with ESA and intravenous iron (66 of 1000; RR 1.82, 95% CI 0.98 to 3.41; moderate certainty) probably slightly increases and with ESA alone (66 of 1000; RR 1.82, 95% CI 1.34 to 2.47; high certainty) slightly increases the number of thromboembolic events. None of the trials reported results on the other comparisons. Thrombocytopenia or haemorrhage We estimated that 76 of 1000 participants without treatment for anaemia developed thrombocytopenia/haemorrhage. Evidence from NMA (13 trials, 2744 participants) suggests that treatment with ESA alone probably leads to little or no difference in thrombocytopenia/haemorrhage (76 of 1000; RR 1.00, 95% CI 0.67 to 1.48; moderate certainty). None of the trials reported results on other comparisons. Hypertension We estimated that 10 of 1000 participants without treatment for anaemia developed hypertension. Evidence from NMA (24 trials; 8383 participants) suggests that treatment with ESA alone probably increases the number of hypertensions (29 of 1000; RR 2.93, 95% CI 1.19 to 7.25; moderate certainty). None of the trials reported results on the other comparisons.

AUTHORS' CONCLUSIONS

When considering ESAs with iron as prevention for anaemia, one has to balance between efficacy and safety. Results suggest that treatment with ESA and iron probably decreases number of blood transfusions, but may increase mortality and the number of thromboembolic events. For most outcomes the different comparisons within the network were not fully connected, so ranking of all treatments together was not possible. More head-to-head comparisons including all evaluated treatment combinations are needed to fill the gaps and prove results of this review.

Problems, Stressors and Needs of Children and Adolescents with Cancer

BACKGROUND

Cancer diseases in children and adolescents are considered to be one of the most serious health problems in the world. It is estimated that about 151,435 cases are diagnosed in children annually. Children with cancer experience many comorbid symptoms related to diagnosis and treatment that can profoundly affect their lives. They experience physical and emotional suffering, which affects their well-being and physical fitness, influencing the prognosis and deteriorating their physical, mental and social functioning. Given the limited data, an attempt was made to assess the problems of the biopsychosocial sphere of need and stressors among children and adolescents treated for cancer. Accurate symptom assessment is essential to ensure high-quality care and effective treatment.

PATIENTS AND METHODS

The qualitative study was conducted in pediatric oncology of hospitals in Poland. Children diagnosed with cancer were invited to participate in the study to assess their problems, stressors and needs.

RESULTS

The study included 520 people, where female sex constituted 48% and male 52%. The mean age of the children is 13.2 SD = 2.5. Negative experiences related to the disease are experienced by 82% of children. Among the surveyed children, the most experienced were anxiety (61%). The conducted research shows that as many as 69% of all respondents experienced states that indicate severe depression. The most common somatic problems reported by children were pain (58%). The most dominant areas of life that had a negative impact was body image (85%).

CONCLUSIONS

Children and adolescents diagnosed with neoplastic disease experience many problems and stressors in every sphere of life, which undoubtedly affects a high level of unmet needs. The main category of needs concerning the challenges faced by children with cancer was psychological and care problems. In the youth group, the needs were mainly related to education and social support.

Outcomes of kidney injury including dialysis and kidney transplantation in pediatric oncology and hematopoietic cell transplant patients

Pediatric oncology and hematopoietic cell transplant (HCT) patients are susceptible to both acute kidney injury (AKI) and chronic kidney disease (CKD). The etiologies of AKI vary but include tumor infiltration, radiation, drug-induced toxicity, and fluid and electrolyte abnormalities including tumor lysis syndrome. HCT patients can also have additional complications such as sinusoidal obstructive syndrome, graft-versus-host disease, or thrombotic microangiopathy. For patients with severe AKI requiring dialysis, multiple modalities can be used successfully, although continuous kidney replacement therapy (CKRT) is often the principal modality for critically ill patients. While increasing numbers of pediatric cancer and HCT patients are now surviving long term, they remain at risk for a number of chronic medical conditions, including CKD. Certain high-risk patients, due to underlying risk factors or treatment-related complications, eventually develop kidney failure and may require kidney replacement therapies. Management of co-morbidities and complications associated with kidney failure, including use of erythropoietin for anemia and potential need for ongoing cancer-related treatment while on dialysis, is an additional consideration in this patient population. Kidney transplantation can be successfully performed in pediatric cancer survivors, although additional features such as specific cancer diagnosis and duration of remission should be considered.

Symptom Experience of Children With Cancer Younger Than Eight Years of Age: An Integrative Review

CONTEXT

Children with cancer endure multiple symptoms during treatment. However, there remains a lack of systematic approaches to capture the whole picture of the symptom experience of children with cancer younger than eight years of age.

OBJECTIVE

The purpose of this study was to conduct an integrative review to explore symptom experience of children with cancer younger than eight years of age.

METHODS

A literature search of PubMed, CINAHL, Web of Science, PsycINFO, Cochrane databases, and four Chinese databases was performed to identify empirical studies, followed by an evaluation of empirical quality and data extraction and synthesis.

RESULTS

Twelve articles covering 11 symptoms met the inclusion criteria. Children with cancer under the age of eight years experienced multiple intense symptoms, especially pain, worry, and anxiety. PedsQL™ Cancer Module (for age five to seven years) was the most commonly used instruments. There were limited data on these children's symptom quality, timing, and distress. Discordance between a child's age and symptom intensity was noted. Inconsistent concordance existed between children and their proxy symptom reports.

CONCLUSION

Children with cancer younger than eight years of age experience multiple symptoms. There is a need to investigate the full symptom profiles of these young children in consideration of their developmental nuances; to examine the concordance among different symptom reporters; and to conduct more qualitative studies to explore their symptom experience.

Association of nutritional status and health-related quality of life in children with chronic kidney disease

PURPOSE

Health-related quality of life (HRQoL) is an important, patient-centred measure. Although nutritional status is altered in children with CKD, the impact of nutritional status on HRQoL in this population has not been explored. The aims of this study are to report the HRQoL scores as assessed by the validated PedsQL™ questionnaire and to explore the relationship of HRQoL scores to markers of nutritional status. It will also examine the concordance between the scores of the child and their parent/carer.

METHODS

A single-centre, cross-sectional, observational study was performed exploring the markers of nutritional status (anthropometry-including presence of obesity, micronutrient status and appetite) and HRQoL and assessed by the PedsQL™ questionnaire in children aged 3-18 years with pre-dialysis, conservatively managed CKD.

RESULTS

A total of 46 children were recruited, with a mean age of 10.5 years. HRQoL scores were lower than in healthy controls throughout all domains. Lower scores were associated with short stature and poor appetite. Markers of obesity or micronutrient status were not associated with HRQoL scores.

DISCUSSION

Nutritional status impacts upon HRQoL. Further study is needed to evaluate how changing nutritional status may affect HRQoL in children with CKD, and this may be used to facilitate the development of patient-centred treatment goals and plans.

PROMIS pediatric measures validated in a longitudinal study design in pediatric oncology

PURPOSE

This study assessed the responsiveness to change over time and theorized associations of Patient-Reported Outcomes Measurement Information System (PROMIS) pediatric measures in children and adolescents in treatment for cancer to determine measure readiness for use in cancer clinical trials.

METHODS

We administered eight PROMIS (three symptom, two psychological, and three performance) pediatric short-form measures and the Symptom Distress Scale (SDS) to 96 pediatric oncology patients at three time points during a course of chemotherapy. We assessed responsiveness using paired t tests and generalized estimating equation (GEE) models, calculated standardized response mean (SRM) values for PROMIS measures, and examined scores over three data points (T1-T3). Guided by the theory of unpleasant symptoms (TOUS), we examined associations among the PROMIS measures, the SDS, and other variables using GEE.

RESULTS

The paired t tests showed statistically significant changes in two psychological measures and one performance measure from T1 to T2; three symptom, two psychological and two performance measures from T2 to T3; and three symptom and two psychological measures from T1 to T3. Findings from GEE models indicate PROMIS pediatric measures had statistically significant short-term and long-term changes, controlling for demographic and clinical variables. One performance measure did not achieve significant change at any time point. We found positive support for theorized relationships in the TOUS.

CONCLUSIONS

Most of the PROMIS pediatric measures demonstrated changes over time and had significant relationships as theorized, thus supporting concurrent and construct validity of these measures when administered to pediatric oncology patients during a course of chemotherapy. This evidence supports the measures' readiness for use in clinical trials.

Child and adolescent self-report symptom measurement in pediatric oncology research: a systematic literature review

OBJECTIVE

Previous work in pediatric oncology has found that clinicians and parents tend to under-report the frequency and severity of treatment-related symptoms compared to child self-report. As such, there is a need to identify high-quality self-report instruments to be used in pediatric oncology research studies. This study's objective was to conduct a systematic literature review of existing English language instruments used to measure self-reported symptoms in children and adolescents undergoing cancer treatment.

METHODS

A comprehensive literature search was conducted in MEDLINE/PubMed, EMBASE, CINAHL, and PsycINFO to identify relevant articles published through November 10, 2016. Using pre-specified inclusion/exclusion criteria, six trained reviewers carefully screened abstracts and full-text articles for eligibility.

RESULTS

There were 7738 non-duplicate articles identified in the literature search. Forty articles met our eligibility criteria, and within these articles, there were 38 self-report English symptom instruments. Most studies evaluated only cross-sectional psychometric properties, such as reliability or validity. Ten studies assessed an instrument's responsiveness or ability to detect changes in symptoms over time. Eight instruments met our criteria for use in future longitudinal pediatric oncology studies.

CONCLUSIONS

This systematic review aids pediatric oncology researchers in identifying and selecting appropriate symptom measures with strong psychometric evidence for their studies. Enhancing the child's voice in pediatric oncology research studies allows us to better understand the impact of cancer and its treatment on the lives of children.

New developments in the management of relapsed/refractory multiple myeloma - the role of ixazomib

Ixazomib is the first oral proteasome inhibitor to be approved, in combination with lenalidomide and dexamethasone, for the treatment of patients with multiple myeloma who have received at least one prior therapy. Approval was on the basis of results from the phase 3, double-blind, placebo-controlled TOURMALINE-MM1 study, which demonstrated a 35% improvement in progression-free survival with the all-oral combination of ixazomib plus lenalidomide-dexamethasone versus lenalidomide-dexamethasone alone (median: 20.6 vs 14.7 months; hazard ratio: 0.74, p=0.012; median follow-up 14.7 months). The addition of ixazomib to the lenalidomide-dexamethasone regimen was associated with limited additional toxicity and had no adverse impact on patient-reported quality of life. Common grade ≥3 adverse events with ixazomib include gastrointestinal adverse events, rash, and thrombocytopenia. Here, we review the efficacy, safety, pharmacokinetics, and patient-reported quality of life data seen with ixazomib, and discuss the role of this oral agent in the treatment of patients with relapsed/refractory multiple myeloma, including in patients with high-risk cytogenetic abnormalities and those with multiple prior therapies.

Voices of children and adolescents on phase 1 or phase 2 cancer trials: A new trial endpoint?

BACKGROUND

Pediatric participants on phase 1 or phase 2 clinical trials for incurable cancer are at risk of experiencing toxicities (adverse events [AEs]) related to trial participation. Multiple AEs are subjective; thus, the real impact of trial treatment cannot be known unless patient subjective reports are solicited.

METHODS

The authors assessed the feasibility and acceptability of soliciting symptom, function, and quality of life (QOL) reports from participants aged 8 to 18 years who were enrolled on phase 1/2 clinical trials at 4 cancer centers during the first course of chemotherapy. The authors also assessed the reliability and validity of 6 self-report Patient-Reported Outcomes Measurement Information System (PROMIS) pediatric measures and 4 open-ended interview questions at 2 time points (at the time of trial enrollment [T1] and 3 to 4 weeks later [T2]).

RESULTS

The enrollment rate of 75.9% (20 participants) exceeded the feasibility criterion, and missingness of measures by person, measure, and items at T1 and T2 were lower than the acceptability criteria. New QOL themes were limited to the impact of treatment on families and being away from home, family, and friends for treatment. All but one measure at T1 met the reliability criterion and all measures did so at T2. Validity support was limited however because as theorized, mobility decreased and fatigue increased as AEs increased.

CONCLUSIONS

Soliciting and documenting symptom, function, and QOL reports from patients aged 8 to 18 years who are enrolled on a phase 1/2 clinical trial is feasible and acceptable to participants, particularly when embedded in trials. Reliable and valid findings can result, making patient self-reported outcomes a possible new trial endpoint. Cancer 2017;123:3799-3806. © 2017 American Cancer Society.

The Antibiotic Drug Tigecycline: A Focus on its Promising Anticancer Properties

Tigecycline (TIG), the first member of glycylcycline bacteriostatic agents, has been approved to treat complicated infections in the clinic because of its expanded-spectrum antibiotic potential. Recently, an increasing number of studies have emphasized the anti-tumor effects of TIG. The inhibitory effects of TIG on cancer depend on several activating signaling pathways and abnormal mitochondrial function in cancer cells. The aim of this review is to summarize the cumulative anti-tumor evidence supporting TIG activity against different cancer types, including acute myeloid leukemia (AML), glioma, non-small cell lung cancer (NSCLC), among others. In addition, the efficacy and side effects of TIG in cancer patients are summarized in detail. Future clinical trials are also to be discussed that will evaluate the security and validate the underlying the tumor-killing properties of TIG.

The effectiveness and cost-effectiveness of erythropoiesis-stimulating agents (epoetin and darbepoetin) for treating cancer treatment-induced anaemia (including review of technology appraisal no. 142): a systematic review and economic model

BACKGROUND

Anaemia is a common side effect of cancer treatments and can lead to a reduction in quality of life. Erythropoiesis-stimulating agents (ESAs) are licensed for use in conjunction with red blood cell transfusions to improve cancer treatment-induced anaemia (CIA).

OBJECTIVE

To investigate the effectiveness and cost-effectiveness of ESAs in anaemia associated with cancer treatment (specifically chemotherapy).

DATA SOURCES

The following databases were searched from 2004 to 2013: The Cochrane Library, MEDLINE, MEDLINE In-Process & Other Non-Indexed Citations, EMBASE, Web of Science, Cumulative Index to Nursing and Allied Health Literature, British Nursing Index, Health Management Information Consortium, Current Controlled Trials and ClinicalTrials.gov. The US Food and Drug Administration and European Medicines Agency websites were also searched. Bibliographies of included papers were scrutinised for further potentially includable studies.

REVIEW METHODS

The clinical effectiveness review followed principles published by the NHS Centre for Reviews and Dissemination. Randomised controlled trials (RCTs), or systematic reviews of RCTs, of ESAs (epoetin or darbepoetin) for treating people with CIA were eligible for inclusion in the review. Comparators were best supportive care, placebo or other ESAs. Anaemia- and malignancy-related outcomes, health-related quality of life (HRQoL) and adverse events (AEs) were evaluated. When appropriate, data were pooled using meta-analysis. An empirical health economic model was developed comparing ESA treatment with no ESA treatment. The model comprised two components: one evaluating short-term costs and quality-adjusted life-years (QALYs) (while patients are anaemic) and one evaluating long-term QALYs. Costs and benefits were discounted at 3.5% per annum. Probabilistic and univariate deterministic sensitivity analyses were performed.

RESULTS

Of 1457 titles and abstracts screened, 23 studies assessing ESAs within their licensed indication (based on start dose administered) were included in the review. None of the RCTs were completely aligned with current European Union licenses. The results suggest a clinical benefit from ESAs for anaemia-related outcomes and an improvement in HRQoL scores. The impact of ESAs on AEs and survival remains highly uncertain, although point estimates are lower, confidence intervals are wide and not statistically significant. Base-case incremental cost-effectiveness ratios (ICERs) for ESA treatment compared with no ESA treatment ranged from £ 19,429 to £ 35,018 per QALY gained, but sensitivity and scenario analyses demonstrate considerable uncertainty in these ICERs, including the possibility of overall health disbenefit. All ICERs were sensitive to survival and cost.

LIMITATIONS

The relative effectiveness of ESAs was not addressed; all ESAs were assumed to have equivalent efficacy. No studies were completely aligned with their European labelling beyond the starting dose evaluated. There is questionable generalisability given that the included trials were published >20 years ago and there have been many changes to chemotherapy as well as to the quality of supportive treatment. Trial quality was moderate or poor and there was considerable unexplained heterogeneity for a number of outcomes, particularly survival, and evidence of publication bias. Adjustments were not made to account for multiple testing.

CONCLUSIONS

ESAs could be cost-effective when used closer to licence, but there is considerable uncertainty, mainly because of unknown impacts on overall survival.

Assessment of quality of life in adolescent patients with cancer and adolescent survivors of childhood cancer

PURPOSE

The aim of the study was to assess the quality of life (QoL) of adolescents with cancer and survivors of childhood cancer as well as the effect of various demographic factors upon it.

DESIGN AND METHODS

The sample of the study included 82 adolescents aged 13-20 years who had been diagnosed with any type of cancer. Twenty-six of them received treatment and 56 survivors of childhood cancer had successfully completed their treatment. Data collection lasted from July 2010 to December 2012 in Children's Hematology-Oncology Unit in Athens. For data collection, Minneapolis-Manchester Quality Questionnaire of Life Instrument was used. The assessment of the QoL of adolescents undergoing treatment was performed with three measurements and that of the survivors with one.

RESULTS

The QoL of adolescent patients did not significantly change during treatment and they showed a satisfactory QoL. Boys scored higher than girls (z = -1.78, p = .04 in psychological function and t = 2.27, p = .02 in body image) as far as QoL in social relations is concerned (z = -2.79, p = .002 in first measurement and z = -2.31, p = .01 in second measurement). Scores on the scale for the QoL of survivors of childhood cancer who completed treatment was 3.91. Survivors showed a higher QoL than the adolescent patients.

CONCLUSIONS

This research has shown that the studied population scored a sufficient QoL, especially survivors of childhood cancer ones. Moreover, their QoL seemed to be influenced by the stage of treatment, the type of cancer, sex, age, family support, and their level of education.

Assessment of quality of life of children and adolescents with cancer during their treatment

OBJECTIVE

The purpose of this study was to evaluate the quality of life of children and adolescents with any type of cancer in all phases of their treatment.

METHODS

Fifty-six newly diagnosed patients diagnosed with malignancy and hospitalized in a Pediatric Hematology-Oncology Unit in Athens were included in the study. Minneapolis-Manchester Quality of Life Instrument was used for data collection from July 2010 to December 2012. The assessment of children and adolescents' quality of life who were under treatment was performed in three different stages of treatment.

RESULTS

The results of the study showed that the quality of life of children and adolescents with cancer did not change notably during their treatment (F = 0.16, P = 0.86 and F = 0.03, P = 0.97). For the first measurement, at the beginning of the therapy, the score on the scale for quality of life for children and adolescents was 3.44 and 3.88, respectively, in the middle of the treatment 3.36 and 3.89, respectively, and 3.43 and 3.89, respectively, when therapy was completed. Children and adolescents diagnosed with hematologic cancer stated higher quality of life scores (z = -1.61, P = 0.05 and t = 2.64, P = 0.007). Moreover, teenage patients (F = 13.22, P = 0.001) and male patients (t = 2.31, P = 0.02 and t = 2.27, P = 0.02) expressed better quality-of-life scores.

CONCLUSION

According to the results, children and adolescents with any kind of cancer have better quality-of-life scores at the end of their treatment, and when they are supported by their family.

The role of iron in the management of chemotherapy-induced anemia in cancer patients receiving erythropoiesis-stimulating agents

BACKGROUND

Erythropoiesis-stimulating agents (ESAs) are commonly used to treat chemotherapy-induced anemia (CIA). However, about half of patients do not benefit.

OBJECTIVES

To evaluate the benefits and harms related to the use of iron as a supplement to ESA and iron alone compared with ESA alone in the management of CIA.

SEARCH METHODS

We searched for relevant trials from the Cochrane Central Register of Controlled Trials (CENTRAL) (issue 1 January 2016), MEDLINE (1950 to February 2016), and www.clinicaltrials.gov without using any language limits.

SELECTION CRITERIA

All randomized controlled trials (RCTs) comparing 'iron plus ESA' or 'iron alone' versus 'ESA alone' in people with CIA were eligible for inclusion.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

We included eight RCTs (12 comparisons) comparing ESA plus iron versus ESA alone enrolling 2087 participants. We did not find any trial comparing iron alone versus ESAs alone in people with CIA. None of the included RCTs reported overall survival. There was a beneficial effect of iron supplementation to ESAs compared with ESAs alone on hematopoietic response (risk ratio (RR) 1.17, 95% confidence interval (CI) 1.09 to 1.26; P < 0.0001; 1712 participants; 11 comparisons; high-quality evidence). Assuming a baseline risk of 35% to 80% for hematopoietic response without iron supplementation, between seven and 16 patients should be treated to achieve hematopoietic response in one patient. In subgroup analyses, RCTs that used intravenous (IV) iron favored ESAs and iron (RR 1.20 (95% CI 1.10 to 1.31); P < 0.00001; 1321 participants; eight comparisons), whereas we found no evidence for a difference in hematopoietic response in RCTs using oral iron (RR 1.04 (95% CI 0.87 to 1.24); P = 0.68; 391 participants; three comparisons). There was no evidence for a difference between the subgroups of IV and oral iron (P = 0.16). There was no evidence for a difference between the subgroups of types of iron (P = 0.31) and types of ESAs (P = 0.16) for hematopoietic response.The iron supplementation to ESAs might be beneficial as fewer participants treated with iron supplementation required red blood cell (RBC) transfusions compared to the number of participants treated with ESAs alone (RR 0.74 (95% CI 0.60 to 0.92); P = 0.007; 1719 participants; 11 comparisons; moderate-quality evidence). Assuming a baseline risk of 7% to 40% for RBC transfusion without iron supplementation, between 10 and 57 patients should be treated to avoid RBC transfusion in one patient.We found no evidence for a difference in the median time to hematopoietic response with addition of iron to ESAs (hazard ratio (HR) 0.93 (95% CI 0.67 to 1.28); P = 0.65; 1042 participants; seven comparisons; low-quality evidence). In subgroup analyses, RCTs in which dextran (HR 0.95 (95% CI 0.36 to 2.52); P = 0.92; 340 participants; three comparisons), sucrose iron (HR 1.15 (95% CI 0.60 to 2.21); P = 0.67; 102 participants; one comparison) and sulfate iron (HR 1.24 (95% CI 0.99 to 1.56); P = 0.06; 55 participants; one comparison) were used showed no evidence for difference between iron supplementation versus ESAs alone compared with RCTs in which gluconate (HR 0.78 (95% CI 0.65 to 0.94); P = 0.01; 464 participants; two comparisons) was used for median time to hematopoietic response (P = 0.02). There was no evidence for a difference between the subgroups of route of iron administration (P = 0.13) and types of ESAs (P = 0.46) for median time to hematopoietic response.Our results indicated that there could be improvement in the hemoglobin (Hb) levels with addition of iron to ESAs (mean difference (MD) 0.48 (95% CI 0.10 to 0.86); P = 0.01; 827 participants; seven comparisons; low-quality evidence). In RCTs in which IV iron was used there was evidence for a difference (MD 0.84 (95% CI 0.21 to 1.46); P = 0.009; 436 participants; four comparisons) compared with oral iron (MD 0.07 (95% CI -0.19 to 0.34); P = 0.59; 391 participants; three comparisons) for mean change in Hb level (P = 0.03). RCTs in which dextran (MD 1.55 (95% CI 0.62 to 2.47); P = 0.001; 102 participants; two comparisons) was used showed evidence for a difference with iron supplementation versus ESAs alone compared with RCTs in which gluconate (MD 0.54 (95% CI -0.15 to 1.22); P = 0.12; 334 participants; two comparisons) and sulfate iron (MD 0.07 (95% CI -0.19 to 0.34); P = 0.59; 391 participants; three comparisons) were used for mean change in Hb level (P = 0.007). RCTs in which epoetin was used showed evidence for a difference with iron supplementation versus ESAs alone (MD 0.77 (95% CI 0.25 to 1.29); P = 0.004; 337 participants; five comparisons) compared with darbepoetin use (MD 0.10 (95% CI -0.13 to 0.33); P = 0.38; 490 participants; two comparisons) for mean change in Hb level (P = 0.02).We found no evidence for a difference in quality of life with addition of iron to ESAs (standardized mean difference 0.01 (95% CI -0.10 to 0.12); P = 0.88; 1124 participants; three RCTs; high-quality evidence).We found no evidence for a difference in risk of grade III-IV thromboembolic events (RR 0.95 (95% CI 0.54 to 1.65); P = 0.85; 783 participants; three RCTs; moderate-quality evidence). The incidence of treatment-related mortality (TRM) was 0% (997 participants; four comparisons; high-quality evidence).Other common adverse events included vomiting, asthenia, and leukopenia, and were similar in both arms.Overall the risk of bias across outcomes was high to low. Since the included RCTs had shorter follow-up duration (up to 20 weeks), the long-term effects of iron supplementation are unknown. Our main reasons for downgrading the quality of evidence were inconsistency across the included studies and imprecision of results.

AUTHORS' CONCLUSIONS

Our systematic review shows that addition of iron to ESAs offers superior hematopoietic response, reduces the risk of RBC transfusions, and improves Hb levels, and appears to be well tolerated. None of the included RCTs reported overall survival. We found no evidence for a difference in quality of life with iron supplementation.

Factors Affecting Health-Related Quality of Life in Children Undergoing Curative Treatment for Cancer: A Review of the Literature

BACKGROUND

Health-related quality of life (HRQoL) is an important measure to evaluate a child's reported treatment experience. Although there are numerous studies of HRQoL in children undergoing curative cancer treatment, there is limited literature on factors that influence this.

OBJECTIVE

To review published studies that describe the HRQoL and associated factors in children undergoing curative cancer treatment.

METHOD

Full-text publications in English from January 2005 to March 2013 were searched in PubMed, PsychINFO, and CINAHL for children ≤18 years of age undergoing curative cancer treatment. HRQoL-associated factors were categorized as cancer diagnosis, treatment, child, family, and community.

RESULTS

Twenty-six studies met the inclusion criteria. The most frequently used generic and cancer-specific instruments were PedsQL (Pediatric Quality of Life Inventory) Generic and PedsQL Cancer, respectively. Cancer diagnosis and treatment were the most frequently identified variables; fewer studies measured family and community domains. Gender, treatment intensity, type of cancer treatments, time in treatment, and cancer diagnosis were correlated with HRQoL.

CONCLUSION

Our study highlights the need to develop interventions based on diagnosis and treatment regimen to improve the HRQoL in children undergoing curative cancer treatment.

Transfusions for anemia in adult and pediatric patients with malignancies

Anemia is present in over two-thirds of patients with malignant hematological disorders. The etiology of anemia predominates from ineffective erythropoiesis from marrow infiltration, cytokine related suppression, erythropoietin suppression, and vitamin deficiency; ineffective erythropoiesis is further exacerbated by accelerated clearance due to antibody mediated hemolysis and thrombotic microangiopathy. As the anemia is chronic in nature, symptoms are generally well tolerated and often non-specific. Transfusion of red blood cells (RBCs) is a balance between providing benefit for patients while avoiding risks of transfusion. Conservative/restrictive RBC transfusion practices have shown equivalent patient outcomes compared to liberal transfusion practices, and meta-analysis has shown improved in-hospital mortality, reduced cardiac events, re-bleeding, and bacterial infections. The implications for a lower threshold for transfusion in patients with malignancies are therefore increasingly being scrutinized. Alternative management strategies for anemia with IV iron and erythropoietin stimulating agents (ESAs) should be considered in the appropriate settings.

The first step to integrating the child's voice in adverse event reporting in oncology trials: a content validation study among pediatric oncology clinicians

PURPOSE

Children with cancer experience significant toxicities while undergoing treatment. Documentation of adverse events (AEs) in clinical trials is mandated by federal agencies. Although many AEs are subjective, the current standard is clinician reporting. Our long-term goal is to create and validate a self-report measure of subjective AEs for children aged 7 years and older that will inform AE reporting for the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE). This content validation study aimed to identify which of the AEs in the current CTCAE should be included in a pediatric self-report measure.

METHODS

We sought expert panel review and consensus among 187 pediatric clinicians from seven Children's Oncology Group institutions to determine which of the 790 AEs are amenable to child self-report. Two survey iterations were used to identify suitable AEs, and clinician agreement estimated by the content-validity ratio (CVR) was assessed.

RESULTS

Response rates for surveys 1 and 2 were 72% and 67%, respectively. After the surveys, 64 CTCAE terms met the criteria of being subjective, relevant for use in pediatric cancer trials, and amenable to self-report by a child. The most frequent reasons for removal of CTCAE terms were that they relied on laboratory or clinical measures or were not applicable to children.

CONCLUSION

The 64 CTCAE terms will be translated into child-friendly terms as the basis of the child-report toxicity measure. Ultimately, systematic collection of these data will improve care by enhancing the accuracy and completeness of treatment toxicity reports for childhood cancer.

Prognostic impact of the combination of erythropoiesis-stimulating agents to cancer treatment: literature review

Cancer patients commonly develop anaemia. Erythropoiesis-stimulating agents (ESAs) are frequently used in cancer treatment. Numerous controlled studies indicate that ESAs can raise haemoglobin levels, reduce transfusion requirements and improve quality of life in anaemic cancer patients receiving chemotherapy. They were previously used to enhance response to radiation therapy, via increasing tumour cell oxygenation. Since the 2002 guideline, there has been increasing attention to the safety of ESA treatment in patients with cancer. Two placebo-controlled phase III randomised clinical trials published in 2003 showed evidence of harmful effects of ESAs on survival and/or tumour outcomes. Subsequently, recent trials and several large meta-analyses have confirmed negative impact on survival and/or disease progression. To comprehensively examine whether ESA use affects safety outcomes in cancer patients in different settings (chemotherapy, radiotherapy and targeted therapies), we conducted a literature review of all clinical trials, small and large meta-analyses from 1990 to 2012.

Quality of life assessment in children commencing home INR self-testing

INTRODUCTION

Management of oral anticoagulant therapy (OAT) in children is complex and frequent testing of the International Normalised Ratio (INR) is a significant burden. This study evaluates the impact of a home INR self-testing (home ST) program on the quality of life (QoL) of children and their families. The aim of the study was to determine if participation in a home ST program improves QoL for children requiring long-term OAT and their families.

MATERIALS AND METHODS

Children aged eight to 18 years requiring long-term OAT and parents of children participated. Quantitative methods comprised three validated QoL questionnaires; the anticoagulation specific PAC QL©, the PedsQL™ and the PedsQL FIM™. Questionnaires were completed before commencing home ST and 6-12 months later. Qualitative methods consisted of open-ended questions which participants answered when completing the questionnaires for the second time. Results of INRs tested at home were collected.

RESULTS

Fifty-five parents and 35 children participated. The percentage of time the children's INRs were in their target therapeutic range was 71.3. Parents reported statistically significant improvements in QoL for themselves (mean increase 6.9), their family (mean increase 8.6) and their child (mean increase 11.1) following the commencement of home ST (difference p≤0.003 on all questionnaires). The children did not report a statically significant improvement in QoL.

CONCLUSION

Parents reported significant improvement for their child's QoL, their QoL and the families' function following commencement of home ST. Children did not report a significant improvement in their QoL, but clearly identified satisfaction with home ST.

Hospital-based home care for children with cancer: feasibility and psychosocial impact on children and their families

BACKGROUND

To assess the feasibility and psychosocial impact of a hospital-based home care (HBHC) program for children with cancer.

PROCEDURE

A HBHC program was carried out with 51 children (0-18 years) with cancer to assess its feasibility in terms of satisfaction, care preferences, safety, and cost. A controlled trial was conducted to assess children's health-related quality of life (HRQOL) using the parent-reported and self-reported PedsQL generic core scale and PedsQL cancer module, and the psychosocial impact on the family by PedsQL family impact module comprising a subsample of 28 children and 43 parents in the home care group, and 47 children and 66 parents receiving standard hospital care.

RESULTS

All parents in the HBHC program were satisfied and preferred home care. There were no serious adverse events associated with HBHC, and costs did not increase. When adjusting for age, gender, diagnosis and time since diagnosis, we found significant higher HRQOL scores in parent-reported physical health (P = 0.04; 95% confidence interval (CI): -0.2-19.5) and worry (P = 0.04; 95% CI: -0.4-20.6) in the home-care group indicating better physical health and less worry for children in the home-care group. No significant difference was found in the Family Impact Module.

CONCLUSION

This study indicates that HBHC is a feasible alternative to hospital care for children with cancer, and is greatly preferred by parents. Specific aspects of children's HRQOL may be improved with HBHC and the psychosocial burden on the family does not increase.

Erythropoietin or darbepoetin for patients with cancer

BACKGROUND

Anaemia associated with cancer and cancer therapy is an important clinical factor in the treatment of malignant diseases. Therapeutic alternatives are recombinant human erythropoiesis stimulating agents (ESAs) and red blood cell transfusions.

OBJECTIVES

To assess the effects of ESAs to either prevent or treat anaemia in cancer patients.

SEARCH METHODS

This is an update of a Cochrane review first published in 2004. We searched the Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE and other databases. Searches were done for the periods 01/1985 to 12/2001 for the first review, 1/2002 to 04/2005 for the first update and to November 2011 for the current update. We also contacted experts in the field and pharmaceutical companies.

SELECTION CRITERIA

Randomised controlled trials on managing anaemia in cancer patients receiving or not receiving anti-cancer therapy that compared the use of ESAs (plus transfusion if needed).

DATA COLLECTION AND ANALYSIS

Several review authors assessed trial quality and extracted data. One review author assessed quality assessment and extracted data, a second review author checked for correctness.

MAIN RESULTS

This update of the systematic review includes a total of 91 trials with 20,102 participants. Use of ESAs significantly reduced the relative risk of red blood cell transfusions (risk ratio (RR) 0.65; 95% confidence interval (CI) 0.62 to 0.68, 70 trials, N = 16,093). On average, participants in the ESAs group received one unit of blood less than the control group (mean difference (MD) -0.98; 95% CI -1.17 to -0.78, 19 trials, N = 4,715). Haematological response was observed more often in participants receiving ESAs (RR 3.93; 95% CI 3.10 to 3.71, 31 trials, N = 6,413). There was suggestive evidence that ESAs may improve Quality of Life (QoL). There was strong evidence that ESAs increase mortality during active study period (hazard ratio (HR) 1.17; 95% CI 1.06 to 1.29, 70 trials, N = 15,935) and some evidence that ESAs decrease overall survival (HR 1.05; 95% CI 1.00 to 1.11, 78 trials, N = 19,003). The risk ratio for thromboembolic complications was increased in patients receiving ESAs compared to controls (RR 1.52, 95% CI 1.34 to 1.74; 57 trials, N = 15,498). ESAs may also increase the risk for hypertension (fixed-effect model: RR 1.30; 95% CI 1.08 to 1.56; random-effects model: RR 1.12; 95% CI 0.94 to 1.33, 31 trials, N = 7,228) and thrombocytopenia/haemorrhage (RR 1.21; 95% CI 1.04 to 1.42; 21 trials, N = 4,507). There was insufficient evidence to support an effect of ESA on tumour response (fixed-effect RR 1.02; 95% CI 0.98 to 1.06, 15 trials, N = 5,012).

AUTHORS' CONCLUSIONS

ESAs reduce the need for red blood cell transfusions but increase the risk for thromboembolic events and deaths. There is suggestive evidence that ESAs may improve QoL. Whether and how ESAs affects tumour control remains uncertain. The increased risk of death and thromboembolic events should be balanced against the potential benefits of ESA treatment taking into account each patient's clinical circumstances and preferences. More data are needed for the effect of these drugs on quality of life and tumour progression. Further research is needed to clarify cellular and molecular mechanisms and pathways of the effects of ESAs on thrombogenesis and their potential effects on tumour growth.

Recombinant human erythropoietin β: the effect of weekly dosing on anemia, quality of life, and long-term outcomes in pediatric cancer patients

Anemia, which is a common problem in cancer patients, has a negative effect on survival by decreasing the efficacy of chemotherapy and particularly of radiotherapy, as well as impairing the quality of life (QoL) of patients. Recombinant human erythropoietin (rHuEPO) decreases a patient's need for transfusions and increases their QoL. The aim of this study was to evaluate the effect of weekly single-dose EPO treatment on transfusion rates, QoL, and hemoglobin (Hb) levels. In addition, patients were followed up for a long period to assess the impact of EPO treatment on survival. The study was conducted from December 2001 to December 2002 in patients with newly diagnosed lymphoma or solid tumors using a prospective and controlled design. EPO-β was given as a single dose of 450 U/kg once a week for 12 weeks. The study and control groups included 16 patients each. Hb levels measured in the study group at the 4th, 8th, and 12th weeks were significantly higher than the values recorded before the start of chemotherapy. In the control group, Hb levels post chemotherapy were significantly lower than values recorded prior to treatment. The increased Hb levels in the study group were significant at the 8th and 12th weeks of treatment compared to levels measured prior to treatment. In the control group, Hb levels at the 4th and 8th weeks were significantly lower than pretreatment levels. When the percent increase of Hb levels of the study and control groups with respect to treatment week was compared, the difference was statistically significant at the 4th, 8th, and 12th weeks. Although the increase on the performance scale within each group during treatment was significant in both the study and control groups, the increase was more marked in the study group. The percent increase on the performance scale with respect to week of treatment was higher in the study group than in the control group. In EPO treatment group, side effects were seen in 38% of patients, with 19% being local pain in the injection area, 13% local hyperemia, and 6% headache. The mean follow-up period of the study and control group was 7.03 ± 0.41 (6.0-7.41) and 7.46 ± 0.45 (6.58-7.83) years, respectively; no statistically significant difference existed between these figures. Overall survival at the end of 7 years of follow-up was 68.8% and 81.3% for the study and control groups, respectively. The use of EPO-β in lymphoma and solid tumor patients on a once-weekly regimen (450 U/kg) was determined to be effective in increasing Hb levels, decreasing transfusion rates, and improving QoL. This regimen was safe, did not cause serious side effects, and can be recommended because of its high patient compliance and tolerability. An effect of EPO on prognosis was not evident. We could not have an explanation on the effect of EPO treatment on prognosis, as there were low number of patients and advanced-staged patients died earlier. Therefore, a larger number of patients are needed to clarify the effect of EPO treatment on prognosis.

Comparing longitudinal assessments of quality of life by patient and parent in newly diagnosed children with cancer: the value of both raters' perspectives

PURPOSE

Health-related quality of life (HRQoL) information from children facing rare and/or life-threatening disease serves important clinical functions. Longitudinal HRQoL ratings from 222 child-parent dyads collected at four time points during the first 16 weeks of cancer treatment are presented. Patient and parent HRQoL reports at the domain level, based on the Pediatric Quality of Life Inventory™ 4.0 Generic Core Scales, were compared over time, and variation in child/parent agreement by age, treatment intensity, and time on treatment was explored.

PATIENTS AND METHODS

Analyses included consideration of missingness, differences between child and parent group mean domain scores averaged over assessments, agreement between individual child and parent, compared to group averages, and within-subject changes between assessments.

RESULTS

Children consistently reported higher functioning than their parents with differences varying by child age and HRQoL domain and diminishing over time. No differences were found by intensity of treatment. The between-subject correlation ranged from 0.61 (social functioning) to 0.86 (physical functioning) across time. Agreement within groups, defined by age, treatment intensity, and time were generally similar.

CONCLUSIONS

Results indicate moderate-to-good child/parent agreement with variability by domain of HRQoL. Findings underscore the complexity of self- and proxy-based report and support the use of information from both raters.

Transfusions increase with nationally driven reimbursement changes of erythropoiesis stimulating agents for chemotherapy-induced anemia

Background. The Centers for Medicare and Medicaid Services (CMS) issued a national coverage determination (NCD) in July 2007, which imposed restrictions on the reimbursement of ESAs for Medicare and Medicaid beneficiaries. Since a majority of our patients are Medicare or Medicaid beneficiaries, we changed our clinical practice regarding the use of erythropoiesis stimulating agents (ESAs) to coincide with the NCD’s reimbursement restriction.

Objective. To evaluate the number of transfusions in patients diagnosed with chemotherapy-induced anemia (CIA) receiving ESAs before and after the clinical practice was changed at the University of Illinois Medical Center (UIMC).

Methods. The medical records of all adult patients diagnosed with a nonmyeloid malignancy and CIA who received an ESA between July 2006 and June 2008 at the UIMC were evaluated. The patients were divided into two groups: patients in receipt of ESAs BEFORE (group 1) and AFTER (group 2). The number of transfusions, the response rates to chemotherapy and ESAs therapy, and overall survival were compared.

Results. Medical records for 110 patients were reviewed. More transfusions were given to patients AFTER we implemented the change in clinical practice (BEFORE 18 transfusions vs. AFTER 52 transfusions, p = 0.004). More patients responded to ESA therapy AFTER we implemented the change (67% vs. 83%, p = NS). The treatment response to chemotherapy and overall survival were similar between the two groups.

Conclusion. The primary goal of reducing the number of transfusions in patients with CIA by administering ESAs cannot be met when clinical practice coincides with the NCD.

Epoetin Alfa in Patients With Advanced-Stage Hodgkin's Lymphoma: Results of the Randomized Placebo-Controlled GHSG HD15EPO Trial

Purpose

To determine whether epoetin alfa reduces anemia-related fatigue, improves other aspects of health-related patient-recorded outcomes (PROs), reduces the number of RBC transfusions, and has an impact on freedom from treatment failure (FFTF) and overall survival (OS) in patients with advanced-stage Hodgkin's lymphoma (HL).

Patients and Methods

The prospectively randomized HD15EPO study performed by the German Hodgkin Study Group investigated epoetin alfa administered at doses of 40,000 U weekly during and after chemotherapy (six to eight cycles of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone [BEACOPP]) in a double-blind, placebo-controlled setting. The study accrued 1,379 patients, of whom 1,328 were assessable for safety, 1,303 were assessable for clinical outcome, and 930 were assessable for PROs.

Results

PROs were not different in patients receiving placebo or epoetin alfa, both after the end of chemotherapy and 6 months thereafter. There was no difference between patients treated with epoetin alfa or placebo with respect to FFTF and OS. There were also no differences in the numbers of deaths, progressions, relapses, and thromboembolic events. The median number of RBC transfusions was reduced from four per patient in the placebo group to two per patient in the epoetin alfa group (P < .001), with 27.4% of patients needing no RBC transfusion in the placebo group compared with 36.7% of patients in the epoetin alfa group (P < .001).

Conclusion

Epoetin alfa administered at 40,000 U weekly parallel to BEACOPP chemotherapy was safe in patients with advanced-stage HL and reduced the number of RBC transfusions but had no impact on fatigue and other PRO domains.

An evaluation of the factors that affect the health-related quality of life of children following myelosuppressive chemotherapy

Purpose

The purposes of this study, in children who were assessed 1 week after the administration of myelosuppressive chemotherapy were: to compare the total and subscale scores on a generic measure of health-related quality of life (HRQOL) to normative data from healthy children and describe the relationships between demographic, clinical, and symptom characteristics of children with cancer and generic and disease-specific dimensions of HRQOL.

Methods

Patients (n = 61) were predominantly male (52.5%), minority (63.9%), and 14.7 years of age. Children completed the Memorial Symptom Assessment Scale for 10- to 18-year olds, the PedsQL™ Generic and Cancer Modules, and the Karnofsky Performance Status (KPS) scale 1 week after the start of a chemotherapy cycle.

Results

The mean number of symptoms per patient was 10.6. Compared with the normative sample, children with cancer reported significantly lower scores for the total scale and all of the subscales except emotional and social functioning. No significant differences were found between any demographic characteristics and total or subscale scores on the generic or disease-specific measures of HRQOL. Lower KPS scores were associated with poorer generic and disease-specific HRQOL scores. In addition, a higher number of symptoms was associated with poorer generic and disease-specific HRQOL scores. Finally, higher symptom distress scores were associated with poorer generic and disease-specific HRQOL scores.

Conclusion

Among the demographic, clinical, and symptom characteristics studied, poorer functional status and higher symptom burden were associated with significant decreases in HRQOL in children who received myelosuppressive chemotherapy.

Erythropoiesis-stimulating agents in oncology: a study-level meta-analysis of survival and other safety outcomes

BACKGROUND: Cancer patients often develop the potentially debilitating condition of anaemia. Numerous controlled studies indicate that erythropoiesis-stimulating agents (ESAs) can raise haemoglobin levels and reduce transfusion requirements in anaemic cancer patients receiving chemotherapy. To evaluate recent safety concerns regarding ESAs, we carried out a meta-analysis of controlled ESA oncology trials to examine whether ESA use affects survival, disease progression and risk of venous-thromboembolic events.

METHODS: This meta-analysis included studies from the 2006 Cochrane meta-analysis, studies published/updated since the 2006 Cochrane report, and unpublished trial data from Amgen and Centocor Ortho Biotech. The 60 studies analysed (15 323 patients) were conducted in the settings of chemotherapy/radiochemotherapy, radiotherapy only treatment or anaemia of cancer. Data were summarised using odds ratios (ORs) with 95% confidence intervals (CIs).

RESULTS: Results indicated that ESA use did not significantly affect mortality (60 studies: OR=1.06; 95% CI: 0.97–1.15) or disease progression (26 studies: OR=1.01; 95% CI: 0.90–1.14), but increased the risk for venous-thromoboembolic events (44 studies: OR=1.48; 95% CI: 1.28–1.72).

CONCLUSION: Though this meta-analysis showed no significant effect of ESAs on survival or disease progression, prospectively designed, future randomised clinical trials will further examine the safety and efficacy of ESAs when used according to the revised labelling information.

Factorial invariance of child self-report across race/ethnicity groups: a multigroup confirmatory factor analysis approach utilizing the PedsQL 4.0 Generic Core Scales

PURPOSE

In order to compare health-related quality of life (HRQOL) research findings across race/ethnicity subpopulations, it is important to demonstrate factorial invariance, i.e., that the items have equivalent meaning across the race/ethnicity groups studied. This study examined the factorial invariance of child self-reported HRQOL across race/ethnicity groups for ages 5-18 years utilizing the 23-item PedsQL 4.0 Generic Core Scales.

METHODS

Multigroup confirmatory factor analysis (CFA) was performed, specifying a five-factor model across four race/ethnicity groups (White Non-Hispanic, Hispanic, Asian/Pacific Islander, Black Non-Hispanic). Multigroup structural equation models were proposed in order to compare the factor structure across the four race/ethnicity subpopulations. The analyses were based on 5,490 children recruited from clinic, school, and community populations.

RESULTS

Strict factorial invariance across the four race/ethnicity groups was demonstrated based on stability of the Comparative Fit Index (CFI) between the models, and several additional indices of practical fit including the Root Mean Squared Error of Approximation (RMSEA), the Non-Normed Fit Index (NNFI), and the Parsimony Normed Fit Index (PNFI).

CONCLUSIONS

The findings support an equivalent five-factor structure across the four race/ethnicity subpopulations studied. Based on these data, it can be concluded that children across the four race/ethnicity groups studied interpreted items in a similar manner regardless of their race/ethnicity.

The pediatric quality of life inventory: measuring pediatric health-related quality of life from the perspective of children and their parents

Health-related quality of life (HRQOL) has been recognized as an important outcome, some contend the most important outcome for children's health care interventions. The PedsQL Measurement Model was designed as a modular approach to measuring pediatric health-related quality of life, developed to integrate the relative merits of generic and disease-specific approaches. We suggest that part of the process of improving the quality of health care includes measuring HRQOL outcomes from the perspective of children and their parents on a routine basis, consistent with a consumer-based health care system approach.

Erythropoietin or Darbepoetin for patients with cancer--meta-analysis based on individual patient data

BACKGROUND

Erythropoiesis-stimulating agents (ESAs) reduce anemia in cancer patients and may improve quality of life, but there are concerns that ESAs might increase mortality.

OBJECTIVES

Our objectives were to examine the effect of ESAs and identify factors that modify the effects of ESAs on overall survival, progression free survival, thromboembolic and cardiovascular events as well as need for transfusions and other important safety and efficacy outcomes in cancer patients.

SEARCH STRATEGY

We searched the Cochrane Library, Medline, Embase and conference proceedings for eligible trials. Manufacturers of ESAs were contacted to identify additional trials.

SELECTION CRITERIA

We included randomized controlled trials comparing epoetin or darbepoetin plus red blood cell transfusions (as necessary) versus red blood cell transfusions (as necessary) alone, to prevent or treat anemia in adult or pediatric cancer patients with or without concurrent antineoplastic therapy.

DATA COLLECTION AND ANALYSIS

We performed a meta-analysis of randomized controlled trials comparing epoetin alpha, epoetin beta or darbepoetin alpha plus red blood cell transfusions versus transfusion alone, for prophylaxis or therapy of anemia while or after receiving anti-cancer treatment. Patient-level data were obtained and analyzed by independent statisticians at two academic departments, using fixed-effects and random-effects meta-analysis. Analyses were according to the intention-to-treat principle. Primary endpoints were on study mortality and overall survival during the longest available follow-up, regardless of anticancer treatment, and in patients receiving chemotherapy. Tests for interactions were used to identify differences in effects of ESAs on mortality across pre-specified subgroups. The present review reports only the results for the primary endpoint.

MAIN RESULTS

A total of 13933 cancer patients from 53 trials were analyzed, 1530 patients died on-study and 4993 overall. ESAs increased on study mortality (combined hazard ratio [cHR] 1.17; 95% CI 1.06-1.30) and worsened overall survival (cHR 1.06; 95% CI 1.00-1.12), with little heterogeneity between trials (I(2) 0%, p=0.87 and I(2) 7.1%, p=0.33, respectively). Thirty-eight trials enrolled 10441 patients receiving chemotherapy. The cHR for on study mortality was 1.10 (95% CI 0.98-1.24) and 1.04; 95% CI 0.97-1.11) for overall survival. There was little evidence for a difference between trials of patients receiving different cancer treatments (P for interaction=0.42).

AUTHORS' CONCLUSIONS

ESA treatment in cancer patients increased on study mortality and worsened overall survival. For patients undergoing chemotherapy the increase was less pronounced, but an adverse effect could not be excluded.

2007 Standards, Options, and Recommendations: use of erythropoiesis-stimulating agents (ESA: epoetin alfa, epoetin beta, and darbepoetin) for the management of anemia in children with cancer

The Standards, Options, and Recommendations (SOR) project undertaken by the French National Federation of Cancer Centers (FNCLCC) to develop and disseminate clinical practice guidelines in oncology has now been taken over by the French National Cancer Institute. In 2007, the SOR updated the information related to the use of erythropoiesis-stimulating agents (ESA) in anemic children with cancer. Updates were based on a review of the most reliable scientific data available, followed by critical appraisal by a multidisciplinary group of experts and validation by independent experts. The literature review identified four randomized trials likely to provide reliable new information on the use of ESA in children. This review confirmed four points: treatment increases hemoglobin levels and decreases the need for blood transfusions; no quality-of-life and no survival benefit has been demonstrated; treatment does not seem associated with significantly more side effects; impact on thromboembolic events and patient quality of life remains unclear. The main result of the study was the elaboration of a new standard of care unavailable at the time of the 2003 version. Systematic administration of ESA is not recommended for the prevention or treatment of anemia in pediatric cancer patients. However, treatment decision must be made on a case-by-case basis and, when treatment is considered, the intravenous route must be preferred.

Using factor analysis to confirm the validity of children's self-reported health-related quality of life across different modes of administration

BACKGROUND

The measurement of pediatric health-related quality of life (HRQOL) in pediatric medicine and health services research has grown significantly over the past decade. While HRQOL instruments are often administered in clinic settings, alternative modes of administration are also utilized such as mail and telephone surveys. In order for comparisons across in-person, mail, and telephone administration to be valid, items on a HRQOL measure must have equivalent meaning across mode of administration. That is, they must demonstrate factorial invariance (stable factor structure) across mode of administration.

PURPOSE

The objective of the present study was to implement the multigroup confirmatory factor analysis (CFA) method for invariance testing across mode of administration for children's self-reported HRQOL.

METHODS

Multigroup CFA was performed specifying a five-factor model across three modes of administration groups (in-person, mail, and telephone survey). The 23-item PedsQL(TM) 4.0 Generic Core Scales was utilized as the measure of children's self-reported HRQOL in a sample of 3741 children ages 5-18.

RESULTS

Strong factorial invariance across the mode of administration groups was demonstrated based on stability of the Comparative Fit Index (CFI) between the models, and several additional indices of practical fit including the Root Mean Squared Error of Approximation (RMSEA), the Non-Normed Fit Index (NNFI), and the Parsimony Normed Fit Index (PNFI).

LIMITATIONS

The mode of administration subpopulations in our study differed with regard to health status.

CONCLUSION

The multigroup CFA statistical methods utilized in the present study have important implications for clinical trials in which mixed modes of administration are used. The present findings support an equivalent five-factor structure of the PedsQL( TM) 4.0 Generic Core Scales across the three modes of administration studied. Based on these data, it can be concluded that children across the three modes of administration groups interpreted items on the PedsQL( TM) 4.0 Generic Core Scales in a similar manner.

Aggressive treatment of non-metastatic osteosarcoma improves health-related quality of life in children and adolescents

BACKGROUND

Health-related quality of life (HRQOL) of paediatric patients with osteosarcoma has not been documented longitudinally during treatment. Aims of this prospective study were to assess treatment effects on patients' HRQOL at diagnosis, during therapy and after completion of therapy, to assess sex- and age-related differences in HRQOL ratings and to assess differences between patients' and parents' reports.

PATIENTS AND METHODS

Sixty-six patients (median age, 13.4 years) with newly diagnosed, localised disease completed three HRQOL instruments, and their parents completed two of the same instruments at diagnosis, before surgery (Week 12), at Week 23 and a median of 20 weeks after treatment completion.

RESULTS

Significant improvements in most domains and worsening of nausea were reported by patients and parents from diagnosis to Weeks 12 and 23. Symptom distress decreased from diagnosis to Weeks 12 and 23 in 81% and 64% of patients, respectively. There were no sex- and few age-related differences in scores. Scores from patients and parents achieved good agreement.

CONCLUSIONS

The HRQOL of patients improves during aggressive treatment for non-metastatic osteosarcoma, except in the domain of nausea. Clinicians can use these findings to prepare their patients for the distressing symptoms that they will likely experience at certain time points and to provide reassurance that these will significantly improve.

Recombinant human erythropoiesis-stimulating agents and mortality in patients with cancer: a meta-analysis of randomised trials

BACKGROUND

Erythropoiesis-stimulating agents reduce anaemia in patients with cancer and could improve their quality of life, but these drugs might increase mortality. We therefore did a meta-analysis of randomised controlled trials in which these drugs plus red blood cell transfusions were compared with transfusion alone for prophylaxis or treatment of anaemia in patients with cancer.

METHODS

Data for patients treated with epoetin alfa, epoetin beta, or darbepoetin alfa were obtained and analysed by independent statisticians using fixed-effects and random-effects meta-analysis. Analyses were by intention to treat. Primary endpoints were mortality during the active study period and overall survival during the longest available follow-up, irrespective of anticancer treatment, and in patients given chemotherapy. Tests for interactions were used to identify differences in effects of erythropoiesis-stimulating agents on mortality across prespecified subgroups.

FINDINGS

Data from a total of 13 933 patients with cancer in 53 trials were analysed. 1530 patients died during the active study period and 4993 overall. Erythropoiesis-stimulating agents increased mortality during the active study period (combined hazard ratio [cHR] 1.17, 95% CI 1.06-1.30) and worsened overall survival (1.06, 1.00-1.12), with little heterogeneity between trials (I(2) 0%, p=0.87 for mortality during the active study period, and I(2) 7.1%, p=0.33 for overall survival). 10 441 patients on chemotherapy were enrolled in 38 trials. The cHR for mortality during the active study period was 1.10 (0.98-1.24), and 1.04 (0.97-1.11) for overall survival. There was little evidence for a difference between trials of patients given different anticancer treatments (p for interaction=0.42).

INTERPRETATION

Treatment with erythropoiesis-stimulating agents in patients with cancer increased mortality during active study periods and worsened overall survival. The increased risk of death associated with treatment with these drugs should be balanced against their benefits.

Biological functions and therapeutic use of erythropoiesis-stimulating agents: perplexities and perspectives

Randomized clinical studies, carried out in patients with haematological malignancies and with solid tumours, have consistently demonstrated that treatment with recombinant human erythropoietin (Epo) increases haemoglobin levels, reduces blood transfusion requirements, and improves the quality of life. In addition, identification of erythropoietin receptor (EpoR) expression on many types of non-erythroid and cancer cells has spurred an interest in the extra-haematological activities of Epo itself and other erythropoiesis-stimulating agents (ESAs). Epo and its derivatives have emerged as major tissue-protective cytokines in ischaemic and degenerative damage of cardiovascular, neurological and renal diseases, while their angiogenetic and immunomodulatory properties indicate that their therapeutic potential may extend well beyond erythropoiesis alone. Both preclinical and clinical data, however, have suggested that they may contribute to tumour progression and prejudice survival when administered to anaemic cancer patients, though the results are equivocal and the assumed mechanisms by which tumour growth could be promoted are not fully understood. While these findings offer new perspectives, they nonetheless demand caution in the employment of ESAs. Further, well-designed experimental and clinical studies are warranted.

Health-related quality of life in adolescents at the time of diagnosis with osteosarcoma or acute myeloid leukemia

Although measuring health-related quality of life (HRQoL) in adolescents with cancer helps clinicians to personalize care for their patients, no previous studies have included HRQoL measurement at the time of diagnosis of osteosarcoma (OS) or acute myeloid leukemia (AML). The purpose of this study was to evaluate the feasibility of measuring adolescents' HRQoL at the time of their diagnosis of OS or AML, and to compare their ratings with those of their parents and of similarly diagnosed but younger patients aged 8-12 years. Participants included 126 patients (79 adolescents) and 130 parents (78 parents of adolescents); most completed the HRQoL instrument/s within 48 h of the first chemotherapy cycle. Ninety-three percent of adolescents diagnosed with OS and 93% of those diagnosed with AML completed the HRQoL instruments. Agreement between the adolescents and their parents ranged from 0.29 to 0.71 (OS) and 0.44 to 0.62 (AML). In all domains, OS adolescents had significantly lower PedsQL v.4.0 scores than adolescents with AML. Our findings demonstrates the feasibility of measuring HRQoL in adolescents with OS or AML (and their parents) at the time of diagnosis, and thus their HRQoL ratings can be used to inform their cancer care from diagnosis forward.

Longitudinal factorial invariance of the PedsQL 4.0 Generic Core Scales child self-report Version: one year prospective evidence from the California State Children's Health Insurance Program (SCHIP)

BACKGROUND

The measurement of health-related quality of life (HRQOL) in pediatric medicine and health services research has grown significantly over the past decade. The paradigm shift toward patient-reported outcomes (PROs) has provided the opportunity to emphasize the value and critical need for pediatric patient self-report. In order for changes in HRQOL/PRO outcomes to be meaningful over time, it is essential to demonstrate longitudinal factorial invariance. This study examined the longitudinal factor structure of the PedsQL 4.0 Generic Core Scales over a one-year period for child self-report ages 5-17 in 2,887 children from a statewide evaluation of the California State Children's Health Insurance Program (SCHIP) utilizing a structural equation modeling framework.

METHODS

Specifying four- and five-factor measurement models, longitudinal structural equation modeling was used to compare factor structures over a one-year interval on the PedsQL 4.0 Generic Core Scales.

RESULTS

While the four-factor conceptually-derived measurement model for the PedsQL 4.0 Generic Core Scales produced an acceptable fit, the five-factor empirically-derived measurement model from the initial field test of the PedsQL 4.0 Generic Core Scales produced a marginally superior fit in comparison to the four-factor model. For the five-factor measurement model, the best fitting model, strict factorial invariance of the PedsQL 4.0 Generic Core Scales across the two measurement occasions was supported by the stability of the comparative fit index between the unconstrained and constrained models, and several additional indices of practical fit including the root mean squared error of approximation, the non-normed fit index, and the parsimony normed fit index.

CONCLUSION

The findings support an equivalent factor structure on the PedsQL 4.0 Generic Core Scales over time. Based on these data, it can be concluded that over a one-year period children in our study interpreted items on the PedsQL 4.0 Generic Core Scales in a similar manner.

Recombinant human erythropoietin beta therapy: an effective strategy to reduce transfusion requirement in children receiving anticancer treatment

In recent years erythropoietic agents have become important tools in the management of anemia in cancer patients, improving hemoglobin (Hb) concentrations, reducing the need for transfusion, and enhancing quality of life. In this prospective and historically controlled study, the effects of epoetin beta on Hb concentrations and red blood cell transfusion needs in children with cancer receiving chemotherapy or radiotherapy have been investigated. Epoetin beta (150 U/kg/day, 3 days a week) was given subcutaneously to 22 children with cancer when Hb concentration < or = 10 g/dL. Data from these patients were compared with those from 20 historical control patients. Hb concentrations were studied weekly in the first 9 weeks, then weekly or fortnightly thereafter. Minimum, maximum, and mean Hb concentrations, frequency of red blood cell transfusion, and the number of red cell packs given were noted. Hb concentrations in weeks 6, 8, and 11 were clearly higher in the study group than the controls. The minimum Hb concentration of the study group was significantly higher than than the control group (7.98 +/- 0.73 [6.70-9.68] g/dL and 7.24 +/- 1.40 [5.50-11.20] g/dL, respectively [p = .038]). A total of 8 units of erythrocyte suspension was given to 4 of the 22 patients in the epoetin group (0.36 unit per patient), while 16 of the 20 patients in the control group received 37 units of erythrocyte suspension in total (1.85 units per patient). The red cell transfusion requirement and the units of transfused erythrocytes per patient were clearly lower in the epoetin group (p < .001 for both of the parameters). No drug-related side effects were noted during epoetin therapy. Epoetin beta therapy provides significant increase in Hb concentrations in children with cancer under anticancer treatment, especially after the sixth week of therapy. Administration of epoetin beta prevents profound decreases in Hb concentrations in the course of therapy and effectively reduces the need for red blood cell transfusions. Epoetin beta was found to be safe and effective in the dosage and the scheme it was used in our study.

Factorial invariance of child self-report across socioeconomic status groups: a multigroup confirmatory factor analysis utilizing the PedsQL 4.0 Generic Core Scales

The measurement of health-related quality of life (HRQOL) in pediatric medicine and health services research has grown significantly over the past decade. Socioeconomic status (SES) differences in health outcomes have been extensively documented in adult and child populations. In order for HRQOL comparisons to be meaningful across different socioeconomic status (SES) groups, items on a HRQOL measure must have equivalent meaning across the SES subpopulations being compared. That is, they must demonstrate factorial invariance. This study examined factorial invariance of child self-report for ages 5-18 across SES groups in 453 children utilizing the PedsQL 4.0 Generic Core Scales. Multigroup Confirmatory Factor Analysis was performed specifying a five-factor model across two SES groups. SES groupings were assigned according to the Hollingshead Index of Social Status. Factorial invariance across socioeconomic status groups was demonstrated based on stability of the Comparative Fit Index (CFI) between the models, and several additional indices of practical fit including the Root Mean Squared Error of Approximation (RMSEA), the Non-Normed Fit Index (NNFI), and the Parsimony Normed Fit Index (PNFI). The findings support an equivalent five-factor structure of child self-report on the PedsQL across the two SES groups studied. Based on these data, it can be concluded that children across SES groups interpreted items on the PedsQL in a similar manner.

Health-related quality of life in sickle cell disease

Advances in drug therapy, hematopoietic stem cell transplantation, and technology have improved the morbidity and survival for those with sickle cell disease. The effect of this modern therapy on the health-related quality of life (HRQL) of those with sickle cell disease is not known. HRQL provides an assessment of how an illness, its complications, and its treatment are experienced by a patient. This review will examine prior work in HRQL in sickle cell disease and the rationale for utilizing HRQL as an outcome to measure impact of treatment. In addition, issues to consider when reporting HRQL will be presented.
