Guideline for the prevention of acute nausea and vomiting due to antineoplastic medication in pediatric cancer patients

[Update of guidelines of the AFSOS, SFRO, SFH, SFNCM, SFCE, GFRP for the management of radio-induced nausea and vomiting]

BACKGROUND

Radiation-induced nausea and vomiting have mutiple clinical consequences: delay or refusal of irradiation (decreased antineoplastic efficacy of irradiation), altered quality of life, dehydration, malnutrition, interruption of treatment, decompensation of comorbidities and aspiration. These guidelines aim at defining good clinical practices for management of radiation-induced nausea and vomiting (RINV).

METHODS

AFSOS, SFRO, SFH, SFNEP, SFCE and GFRP applied an expert consensus methodology to propose updated guidelines.

RESULTS

RINV are underdiagnosed and undertreated. Assessment of the emetogenic risk depends on two main factors: 1) the irradiated anatomical localization and 2) the associated concomitant chemotherapy. In case of exclusive radiotherapy, primary antiemetic prophylaxis depends on the emetogenic risk of irradiated anatomical localization. Primary antiemetic prophylaxis is initiated at the onset of irradiation and continues until 24h after the end of the irradiation. In the case of concomitant radiochemotherapy, the emetogenic risk is generally higher for chemotherapy and the primary antiemetic prophylaxis corresponds to that of chemo-induced nausea and vomiting. In the case of persistence of these symptoms, subject to a well-conducted treatment, a rigorous diagnostic procedure must be carried out before being attributed to radiotherapy and precise evaluation of their impact. Remedial treatments are less well codified.

CONCLUSION

It is essential to know and good management practices for radiation-induced nausea and vomiting.

Clinical practice guideline-inconsistent chemotherapy-induced vomiting prophylaxis in pediatric cancer patients in community settings: A Children's Oncology Group study

BACKGROUND

This study aimed to determine the proportion of patients receiving clinical practice guideline (CPG)-inconsistent care related to chemotherapy-induced vomiting (CIV) prophylaxis, and to describe the association between CPG-inconsistent care and site size. The association between delivery of CPG-inconsistent care and patient outcomes (CIV control, admission prolongation, and unplanned healthcare visits) was also described.

METHODS

This was a retrospective study conducted at Children's Oncology Group (COG) National Cancer Institute Community Oncology Research Program (NCORP) sites. Eligible patients received highly (HEC) or moderately emetogenic chemotherapy (MEC) as inpatients from January 2014 through December 2015, and were previously enrolled in a COG study. The COG generated a patient list from which patients were randomly selected for chart review by participating sites. A central panel adjudicated CIV prophylaxis received as CPG-consistent or -inconsistent.

RESULTS

Twenty-four sites participated. Over half of patients received CPG-inconsistent CIV prophylaxis (HEC: 59/112, 52.6%; MEC: 119/215, 55.3%). The most common reasons for CPG-inconsistency were shortened duration of antiemetic administration or omission of dexamethasone. Site size was not found to be associated with CPG-inconsistent care delivery (HEC: adjusted odds ratio [OR]: 0.96, 95% confidence interval [CI]: 0.76-1.23; MEC: adjusted OR: 1.07; 95% CI: 0.92-1.24). Additionally, there was no statistically significant association between receipt of CPG-inconsistent care and patient outcomes.

CONCLUSIONS

Patients receiving MEC or HEC often received CPG-inconsistent CIV prophylaxis. Site size was not associated with receipt of CPG-inconsistent care. Future studies should evaluate strategies to improve CIV control among pediatric oncology patients including those aimed at improving CPG adherence.

Impact of dexamethasone on transplant-related mortality in pediatric patients: a multi-site, propensity score-weighted, retrospective assessment

Dexamethasone use during hematopoietic cell transplant (HCT) conditioning varies between pediatric centers. This study aimed to estimate the difference in 1-year treatment-related mortality (TRM) between patients who did or did not receive dexamethasone during HCT conditioning. Secondary objectives were to estimate the difference between dexamethasone-exposed and dexamethasone-unexposed groups in 1-year event-free survival (EFS), time to neutrophil engraftment, acute graft-versus-host disease (aGVHD), and invasive fungal disease (IFD) at day + 100. This was a seven-site, international, retrospective cohort study. Patients < 18 years old undergoing their first allogeneic or autologous myeloablative HCT for hematologic malignancy or aplastic anemia between January 1, 2012, and July 31, 2017, were included. To control for potential confounders, propensity score weighting was used to calculate the standardized mean difference for all endpoints. Among 242 patients, 140 received dexamethasone during HCT conditioning and 102 did not. TRM was unaffected by dexamethasone exposure (1.7%; 95% CI - 7.4, 10.2%). Between-group differences in secondary outcomes were small. However, dexamethasone exposure significantly increased possible, probable, and proven IFD incidence (9.0%, 95% CI 0.8, 17.3%). TRM is not increased in pediatric patients who receive dexamethasone during HCT conditioning. Clinicians should consider potential IFD risk when selecting chemotherapy-induced vomiting prophylaxis for pediatric HCT patients.

Outcome of antiemetic prophylaxis among pediatric cancer patients receiving moderate to highly emetogenic chemotherapy at pediatric hemato-oncology ward of Tikur Anbessa specialized hospital: A prospective observational study

INTRODUCTION

Chemotherapy-induced nausea and vomiting (CINV) is a major issue for chemotherapy pediatric patients, especially in developing countries due to limited access to essential antiemetics. This study aimed to assess antiemetic prophylaxis outcomes in pediatric cancer patients at Tikur Anbessa Specialized Hospital in Addis Ababa, Ethiopia.

METHODS

A longitudinal prospective observational study design was conducted among 201 pediatric cancer patients followed up to 120 h post-chemotherapy.

RESULTS

The majority of patients (75.1%) received combination prophylactic antiemetics in the acute phase. Complete response (CR) was the highest in the acute phase (71.1%). Emesis episodes occurred most frequently on the first day of treatment (28.4%) and gradually decreased over time. History of motion sickness, platinum-based chemotherapy, and prior chemotherapy-induced vomiting (CIV) were associated with emesis during the acute phase whereas multiple-day chemotherapy, prior CIV, receipt of antiemetics, and a history of motion sickness in the delayed phase. However, the odds of CIV were reduced with steroid presence in the chemotherapy regimen.

CONCLUSIONS

A considerable number of participants could not achieve a CR. It is important for clinicians to be cognizant of risk factors that influence the outcome of antiemetic prophylaxis to achieve better control of CINV among pediatric cancer patients.

Palonosetron in pediatric patients: A single-center, retrospective evaluation of policy and clinical practice guideline discordance

INTRODUCTION

Clinical practice guidelines (CPGs) recommending palonosetron for the prevention and management of chemotherapy-induced nausea and vomiting (CINV) were adapted for use at our institution. Palonosetron was restricted for use in patients experiencing breakthrough CINV and receiving highly emetogenic chemotherapy (HEC) or undergoing stem cell transplant conditioning and in patients with refractory CINV receiving HEC. Given the significant cost of palonosetron, we aimed to determine the proportion of chemotherapy blocks where palonosetron use was discordant with the institutional policy or source CPG.

METHODS

A retrospective review of the health records of patients who received palonosetron between 1 July 2019 and 30 June 2020 was undertaken. Details of palonosetron use, antiemetic regimen and the date and time of each vomit during the acute and delayed phases were collected for each chemotherapy block where palonosetron was given. Discordance with the institutional policy and the source CPG was determined by assessing the indication for palonosetron and the dose. In the subset of chemotherapy blocks where information regarding vomiting episodes was available, the extent of acute phase chemotherapy-induced vomiting (CIV) control was reported.

RESULTS

Four hundred thirty-eight chemotherapy blocks, representing 122 patients (mean age 9 years), receiving 595 palonosetron doses were included. Palonosetron use was discordant with institutional policy during most (72%; 314/438) of the chemotherapy blocks analyzed. However, palonosetron use was concordant with the source CPG during most chemotherapy blocks (74%; 326/438). Complete CIV control during the acute phase was observed in 66% (195/295) of chemotherapy blocks where palonosetron was given, irrespective of concomitant antiemetics administered.

CONCLUSION

The majority of palonosetron use at our institution was discordant with institutional policy, but concordant with the source CPG. Our institutional policy has since been updated to be more aligned with the source CPG.

Vomiting after intrathecal chemotherapy under anesthesia in pediatric patients with hematologic cancers: A cohort study

INTRODUCTION

Despite preventive strategies, vomiting is an adverse event affecting patients with cancer. However, literature on the incidence and risk factors for vomiting in pediatric patients with cancer are scarce.

AIM

To assess the incidence and risk factors for vomiting within 24 h and goodness of fit for the Eberhart score in pediatric patients with hematologic cancers after receiving intrathecal chemotherapy under deep sedation.

METHODS

This prospective cohort study included patients under 20 years of age with hematologic cancers who were scheduled to undergo intrathecal chemotherapy under anesthesia. The primary outcome was the occurrence of vomiting within 24 h after the end of anesthesia. Sociodemographic and procedure data and underlying diseases were collected. Patients were monitored during the procedure, in the postanesthesia care unit, and the day after (by phone call).

RESULTS

A total of 139 patients were included, and the incidence of vomiting was 30.9% within 24 h after intrathecal chemotherapy under anesthesia, with 90.7% of vomiting prior to 6 h. Prophylactic ondansetron was administered prior to the procedure to 45.3% of patients. Risk factors for vomiting were female gender (hazard ratio: 2.47, 95% confidence interval: 1.35-4.53, p: .003), consolidation phase of treatment (hazard ratio: 2.16, 95% confidence interval: 1.10-4.24, p: .025), and history of kinetosis (hazard ratio: 2.49, 95% confidence interval: 1.31-4.70, p: .005). Incidence of vomit was higher than estimated by the Eberhart score distribution (observed incidence in patients with a score of zero: 33.3%; with a score of one: 28.8%; with a score of two: 60%).

CONCLUSION

A high incidence of vomiting was observed within 24 h after intrathecal chemotherapy under propofol deep sedation. Risk factors for this outcome were established (being female, consolidation phase of treatment, and previous kinetosis), and evidence suggested that the Eberhart score was not suitable for the studied population.

Children's Oncology Group 2023 blueprint for research: Cancer care delivery research

The National Cancer Institute (NCI) has a 40-year history of initiatives to encourage the participation of community oncology sites into clinical trials research and clinical care. In 2014, the NCI re-organized to form the NCI Community Oncology Research Program (NCORP) network across seven research bases, including the Children's Oncology Group (COG), and numerous community sites. The COG portfolio for Cancer Care Delivery Research (CCDR), mirroring the larger NCORP network, has included two studies addressing guideline congruence, as an important marker of quality cancer care, and another focusing on financial toxicity, addressing the pervasive problems of healthcare cost. CCDR is a cross-cutting field that frequently examines intersectional aspects of healthcare delivery. With that in mind, we explicitly define domains of CCDR to propel our research agenda into the next phase of the NCORP CCDR program while acknowledging the complex and dynamic fields of clinical care, policy level decisions, research findings, and needs of communities served by the NCORP network that will inform the subsequent research questions. To ensure programmatic success, we will engage a broad interdisciplinary group of investigators and clinicians with expertise and dedication to community oncology and the populations they serve.

The Effect and Safety of Olanzapine on Nausea and Vomiting in Children Receiving Moderately Emetogenic Chemotherapy

Background

In order to improve the complete recovery of nausea and vomiting, we conducted a study with the aim of preventing acute and delayed nausea and vomiting in children undergoing moderate emetogenic chemotherapy.

Materials and Methods

A clinical trial study was done on 130 children received chemotherapy. Patients received olanzapine and placebo. All groups received granisetron along with dexamethasone (DEX). The severity of chemotherapy-induced nausea and vomiting (CINV) induced by chemotherapy was compared in two groups.

Results

The severity of nausea on the first, second, third, and fourth days was not significantly different (P > .05) in two groups. The number of patients without vomiting was significantly different during the first 24 hours after chemotherapy between patients in the two groups (82.3% vs 64.5%; P = .016).

Conclusion

This study showed that olanzapine, which acts as an inhibitor of neurotransmitters, had a favorable efficacy in controlling acute and delayed CINV. More studies with large sample size are needed to compare the effect of olanzapine with other agents including aprepitant and palonosetron in the prevention of CINV.

Chemo assist for children mobile health application to manage chemotherapy-related symptoms in acute leukemia in Indonesia: a user-centered design approach

BACKGROUND

A mobile health (mHealth) application can encourage parents and pediatric patients to be involved in caring for their child's health condition by providing the ability to identify and actively manage chemotherapy-related symptoms in their child. Several monitoring systems available today are diverse in features and system basis. This study aimed to develop and trial the Chemo Assist for Children (CAC) mHealth application for symptom management in children with acute lymphoblastic leukemia (ALL).

METHODS

In this study, the development of the CAC application went through multiple phases and methods. Study phases included: (1) development of the application's feature based on the need assessment, (2) creation of content of application based on literature review, (3) develop prototyping of CAC, (4) expert review and feedback on the application content, (5) usability testing by targeted end-user.

RESULTS

Based on need assessment, it was determined that parents with leukemia children were interested in symptom management of chemotherapy and preferred mobile applications. Therefore, a mHealth application was designed to include features to identify symptoms and provide recommendation strategies to manage the symptom. Usability evaluation by end-user revealed that mHealth is a valid, accessible, and appropriate application for users.

CONCLUSIONS

The CAC mHealth application developed can meet the needs of technology users to identify symptoms and manage chemotherapy-related symptoms in children with ALL. The CAC mHealth application can accommodate data not recorded at out-of-hospital care, increase the independence of symptom management, and improve communication between parents of children with ALL and health workers.

Addressing adherence to guidelines on prevention of acute chemotherapy-induced nausea and vomiting in pediatric patients

BACKGROUND

Chemotherapy-induced nausea and vomiting (CINV) is a distressing adverse effect in children receiving cancer treatment. There are evidence-based pediatric clinical practice guidelines (CPG) on chemotherapy emetogenicity and acute CINV prevention, but adherence to these guidelines is low.

PROCEDURE

A quality improvement-based study was conducted at McMaster Children's Hospital. The SMART aim was to increase adherence to guidelines on prevention of acute CINV in hospitalized patients receiving high (HEC) and moderately emetogenic chemotherapy (MEC) from baseline 25% to more than 70% by June 2021. Barriers were identified by process mapping, and a series of interventions were implemented.

RESULTS

Guideline adherence was assessed in 270 inpatient chemotherapy administrations (HEC, MEC). Data were collected on 131 charts pre interventions and 139 charts post interventions. Interventions included education, addition of guideline-recommended anti-emetics to the inpatient formulary, and implementation of a standardized CPG tool. Initial rates of total CINV guideline adherence were 25%, which improved to 72% post intervention (p < .001). In subgroup analysis, guideline adherence in the MEC group improved from 13% to 34% (p = .015), and in the HEC group from 32% to 93% (p < .001). The most common reason for nonadherence in the HEC group was failure to use aprepitant as anti-emetic, and in MEC was option for ondansetron monotherapy prophylaxis.

CONCLUSION

Using quality improvement methodology, barriers to guideline adherence were identified and interventions implemented. Guideline adherence for prevention of CINV improved, particularly in the HEC group but less for the MEC group. Future steps will include sustainability of interventions and addressing adherence in the MEC group.

The emerging role of olanzapine in paediatric CINV control: A review

Chemotherapy-induced nausea and vomiting (CINV) is a serious side effect of chemotherapy that negatively impacts the quality of life of oncological patients and is associated with the emetogenic risk specific to administered chemotherapy. Current practice guidelines on the use of antiemetics in CINV include the option of adding olanzapine to antiemetic regimens in the management of adult CINV. The use of olanzapine in pediatric CINV has been restricted to children with poor CINV control. Research on the use of olanzapine in pediatric CINV has been limited. The aim of this review was to evaluate current evidence on the effective and safe antiemetic use of olanzapine in pediatric CINV of any type following chemotherapy of any emetogenicity. Ovid MEDLINE, Embase, CENTRAL databases were searched for any literature on the use of olanzapine in pediatric CINV published from 2015 to 2022. Studies that reported on the olanzapine-containing antiemetic regimen in peadiatric CINV control specifically were included. Search restrictions were placed on research published in English. The search generated 43 records that were assessed for eligibility. Out of 10 identified eligible studies a third were RCT. Findings of this review suggest that adding olanzapine to antiemetic regimen in pediatric CINV control is a worthwhile consideration. Further research is needed to establish the efficacy and safety of antiemetic olanzapine use in pediatric CINV.

Prevention of acute and delayed chemotherapy-induced nausea and vomiting in pediatric cancer patients: A clinical practice guideline

This clinical practice guideline provides recommendations for preventing acute and delayed phase chemotherapy-induced nausea and vomiting (CINV) in pediatric patients. The recommendations are based on two systematic reviews of randomized controlled trials evaluating interventions to prevent (1) acute phase CINV and (2) delayed phase CINV. Recommendations for acute phase and delayed phase CINV prophylaxis are made for patients receiving chemotherapy of varying emetogenicity, as well as for patients not able to receive dexamethasone or a neurokinin-1 receptor antagonist. Evidence gaps, including antiemetic safety and optimal dosing, were identified.

Interventions for the prevention of acute phase chemotherapy-induced nausea and vomiting in adult and pediatric patients: a systematic review and meta-analysis

PURPOSE

To identify effective and safe interventions to prevent acute phase chemotherapy-induced nausea and vomiting (CINV) in adult and pediatric patients.

METHODS

We conducted a systematic review of randomized trials evaluating interventions to prevent acute CINV. Outcomes assessed were complete chemotherapy-induced vomiting (CIV) control, complete chemotherapy-induced nausea (CIN) control, complete CINV control, and discontinuation of antiemetics due to adverse effects.

RESULTS

The search identified 65,172 citations; 744 were evaluated at full-text, and 295 (25 pediatric) met eligibility criteria. In patients receiving highly emetogenic chemotherapy (HEC), complete CIV (risk ratio (RR) 1.23, 95% confidence interval (CI) 1.05-1.44) and CIN (RR 1.34, 95% CI 1.10-1.62) control improved when olanzapine was added. The addition of a neurokinin-1 receptor antagonist (NK1RA) to a corticosteroid plus a serotonin-3 receptor antagonist (5HT3RA) also improved complete CIV (RR 1.11, 95% CI 1.08-1.14) and CIN (RR 1.05, 95% CI 1.01-1.08) control. Compared to granisetron/ondansetron, palonosetron provided improved complete CIV control when the 5HT3RA was given alone or when combined with dexamethasone. In patients receiving moderately emetogenic chemotherapy (MEC), dexamethasone plus a 5HT3RA improved complete CIV control compared to a 5HT3RA alone (RR 1.29, 95% CI 1.21-1.39). Only a single meta-analysis evaluating the safety outcome was possible.

CONCLUSIONS

For patients receiving HEC, various antiemetic regimens improved CIV and CIN control. For patients receiving MEC, administration of a 5HT3RA plus dexamethasone improved CIV control. Analysis of antiemetic safety was constrained by lack of data.

[Antineoplastic drug-induced nausea and vomiting in pediatric onco-hematology: 2022: Guidelines from the supportive care committee of the French Society of Childhood Cancer (SFCE)]

Nausea and vomiting induced by cancer treatment (CINV) remain one of the most common and feared side effects in children despite the use of new drugs to prevent them. The existing recommendations for the prophylaxis and treatment of CINV are based on adult patients in Anglo-Saxon societies. Based on a recent review of the literature, we focused on specific pediatric issues in order to offer recommendations validated by the supportive care committee of the French society for childhood cancer.

Optimizing antiemetic therapy for children undergoing chemotherapy

Chemotherapy-induced nausea and vomiting (CINV) is a common side effect of most chemotherapy agents. Suboptimal management of CINV impacts quality of life, nutrition, gastrointestinal (GI) integrity, and adherence to chemotherapy treatment plans. This article reviews the principles of CINV management, planning and implementation of antiemetic regimens, and pharmacology of the antiemetics currently available in the United States appropriate for pediatric use. With the advent of more targeted therapies, increased use of immunotherapy, and the effects of radiotherapy to the brain, spine, and abdomen, treatment of CINV now has a broader application than just for chemotherapeutics alone.

Does Creative Arts Therapy Improve Distressing Symptoms in Children with Cancer? A Synthesis of Extant Literature

Introduction: Children with cancer experience symptom distress which has been correlated with decreased quality of life (QOL). Creative arts therapy (CAT) encompasses the therapeutic use of creative arts which may improve QOL among children with cancer by affecting symptoms. Therefore, the research question was asked: Does CAT affect symptoms of pain, nausea, fatigue, anxiety, and mood in children with cancer? Methods: Based on the study question, a comprehensive literature search of PubMed, CINAHL, PsycINFO, and Embase was completed. Inclusion criteria limited articles to specific symptom outcomes in two-group intervention studies in the English language. Selected articles were confirmed for inclusion by the study team, followed by group discussion to develop matrices with levels of evidence based on the Grading of Recommendations Assessment, Development, and Evaluation (Grade) guidelines. Results: Initial searches revealed 1,391 articles, screened to 44 for systematic review. Based on the inclusion criteria, 11 articles remained. Four studies had evidence levels graded as low, three were low to moderate, and four were moderate. Outcomes of mood and anxiety were measured in five studies, pain in four, fatigue in two, and nausea in one study. Discussion: Psychological outcomes were measured more commonly than physical outcomes. Evidence reached a moderate grade in four studies. Summary: Through this synthesis of intervention studies with CAT in children with cancer, improvement in distressing symptoms has potential, but the state of the science for symptom management with CAT could be strengthened for nurses to promote CAT to improve QOL among children with cancer.

Key articles and guidelines for the pediatric clinical pharmacist from 2019 and 2020

PURPOSE

To summarize recently published research reports and practice guidelines deemed to be significantly impactful for pediatric pharmacy practice.

SUMMARY

Our author group was composed of 8 board-certified pediatric pharmacists. Eight major themes were identified: critical care, hematology/oncology, medication safety, general pediatrics, infectious diseases, neurology/psychiatry, gastrointestinal/nutrition, and neonatology. The author group was assigned a specific theme(s) based on their practice expertise and were asked to identify articles using MEDLINE and/or searches of relevant journal articles pertaining to each theme that were published from January 2019 through December 2020 that they felt were "significant" for pediatric pharmacy practice. A final list of compiled articles was distributed to the authors, and an article was considered significant if it received a vote from 5 of the 8 authors. Thirty-two articles, including 16 clinical practice guidelines or position statements and 16 review or primary literature articles, were included in this review. For each of these articles, a narrative regarding its implications for pediatric pharmacy practice is provided.

CONCLUSION

Given the heterogeneity of pediatric patients, it is difficult for pediatric pharmacists to stay up to date with the most recent literature, especially in practice areas outside their main expertise. Over the last few years, there has been a significant number of publications impacting the practice of pediatric pharmacists. This review of articles that have significantly affected pediatric pharmacy practice may be helpful in staying up to date on key articles in the literature.

Improving Guideline-Congruent Care for Chemotherapy-Induced Nausea and Vomiting Prophylaxis in Pediatric Oncology Patients

PURPOSE

Chemotherapy-induced nausea and vomiting (CINV) is a very common side effect of pediatric cancer therapy. High-quality, evidence-based, pediatric-specific guidelines for prophylaxis and treatment of CINV are available. At many centers, guideline-concordant care is uncommon. We formed a multidisciplinary quality improvement team to implement guideline-concordant care for CINV prophylaxis at our center. We present the results following the first year of our interventions.

METHODS

We planned and implemented a multipronged approach in three key phases: (1) developing and publishing an acute CINV prophylaxis pathway, (2) education of providers, and (3) updating the computerized provider order entry system. We used iterative, sequential Plan-Do-Study-Act cycles and behavioral economic strategies to improve adherence to guideline-concordant CINV prophylaxis. We focused on aprepitant usage as a key area for improvement.

RESULTS

At the beginning of the study period, < 50% of patients were receiving guideline-concordant CINV prophylaxis and < 15% of eligible patients were receiving aprepitant. After 1 year, more than 60% of patients were receiving guideline-concordant care and 50% of eligible patients were receiving aprepitant.

CONCLUSION

We describe the development and implementation of a standardized pathway for prevention of acute CINV in pediatric oncology patients. With a multidisciplinary, multifaceted approach, we demonstrate significant improvements to guideline-congruent CINV prophylaxis.

A Person-Centered Approach to Symptom Assessment and Management for Children and Adolescents Receiving Cancer Treatment

OBJECTIVES

Discuss the clinical assessment and management of symptoms for children and adolescents receiving treatment for cancer with attention to a person-centered approach to care.

DATA SOURCES

Review of currently published literature and guidelines pertaining to symptom assessment and management for children and adolescents receiving treatment for cancer.

CONCLUSION

Symptoms such as pain, nausea, and fatigue are commonly reported by children and adolescents receiving cancer treatment and are associated with greater symptom burden. Symptom assessment should be tailored to the child or adolescent and include the child's or adolescent's preference for reporting symptoms and attention to the symptoms that are of greatest priority. Evidence-based guidelines for the management of symptoms, including pain and nausea, are available to guide symptom management interventions and should be tailored to provide person-centered care.

IMPLICATIONS FOR NURSING PRACTICE

Nurses can lead efforts through clinical practice and research initiatives to advance person-centered symptom care for children and adolescents with cancer on a global level. Priorities for future work to advance person-centered symptom assessment and management include (1) identification of best practices for symptom assessment, (2) attention to social determinants of health and their subsequent influence on symptom outcomes, (3) compilation of evidence for management of less commonly reported symptoms, and (4) implementation of published clinical guidelines for symptom management in practice settings.

Single daily dosing versus divided dosing intravenous ondansetron to prevent chemotherapy-induced nausea and vomiting among children: A comparative randomized double-blind controlled trial

BACKGROUND

Chemotherapy-induced nausea and vomiting (CINV) is a common complication in cancer treatment. Ondansetron is an effective antiemetic drug widely used to prevent CINV; however, the effective administrative dosing strategies among pediatrics remain unclear. The study aimed to investigate clinical effectiveness of single daily dosing versus divided dosing ondansetron.

METHODS

In all, 194 children undergoing chemotherapy were randomized to receive either single daily dosing (0.3 mg/kg/dose) or divided dosing (0.15 mg/kg/dose every 8 hours) intravenous ondansetron for 24 hours. Clinical parameters including number of emesis episodes, nausea scores, appetite levels, parent's satisfaction, and adverse effects within 24 hours were analyzed.

RESULTS

No significant differences were found between the two dosing strategies concerning number of emesis episodes and parent's satisfaction. However, nonleukemic hematologic malignancies and concurrent administration of intrathecal methotrexate-hydrocortisone-cytarabine (IT-MHA) were associated with increased risk of acute-phase vomiting. Interestingly, none of the patients aged under 7 years, receiving divided dosing ondansetron, presented nausea symptoms compared with those receiving single daily dosing (p-value .034). No significant differences regarding headache were observed between the two dosing strategies and none of the patients experienced QTc prolongation.

CONCLUSION

Ondansetron administered as divided dosing should be considered among children aged under 7 years to prevent chemotherapy-induced nausea and among patients receiving low emetogenic chemotherapy to maintain their appetite. Both administrative dosing strategies were well tolerated with no significant adverse effects.

Prevention and treatment of anticipatory chemotherapy-induced nausea and vomiting in pediatric cancer patients and hematopoietic stem cell recipients: Clinical practice guideline update

This 2021 clinical practice guideline update provides recommendations for preventing anticipatory chemotherapy-induced nausea and vomiting (CINV) in pediatric patients. Recommendations are based on systematic reviews that identified (1) if a history of acute or delayed CINV is a risk factor for anticipatory CINV, and (2) interventions for anticipatory CINV prevention and treatment. A strong recommendation to optimize acute and delayed CINV control in order to prevent anticipatory CINV is made. Conditional recommendations are made for hypnosis, systematic desensitization, relaxation techniques, and lorazepam for the secondary prevention of anticipatory CINV. No recommendation for the treatment of anticipatory CINV can be made.

Delirium documentation in hospitalized pediatric patients with cancer

OBJECTIVE

Screening tools for delirium are being used more consistently in pediatric critical care. However, screening is not universal, and delirium may be underdiagnosed, misdiagnosed, or undocumented in hospitalized patients. We evaluated the identification and documentation of delirium in pediatric oncology and bone marrow transplant patients.

METHOD

A retrospective chart review on all hospitalized pediatric oncology and bone marrow transplant patients admitted to an Academic Cancer center between 2013 and 2016. Patients aged less than 21 years of age with active cancer were included. Patients with major psychiatric conditions, developmental delays, or autism were excluded. Data were collected to characterize documentation concerning the identification and diagnosis of delirium.

RESULTS

Of 201 hospitalization records, 54 (26.9%) admissions from 109 unique patients had documentation of delirium. The overall documented incidence of delirium was 3.2% of hospitalizations or 8.2% of unique patients. Patients prescribed opioids and benzodiazepines were more likely to have documentation of delirium. ICD coding under-reported delirium while physician documentation was inaccurate in 26% (53/201) when compared with the chart review.

SIGNIFICANCE OF RESULTS

Delirium was frequently undocumented or miscoded. Implementing a validated, universal screening tool for delirium may improve identification and clinical outcomes.

Dexamethasone dosing for prevention of acute chemotherapy-induced vomiting in pediatric patients: A systematic review

A systematic review was undertaken to describe dexamethasone doses studied for chemotherapy-induced vomiting (CIV) prophylaxis in pediatric patients and their effects on achieving complete acute CIV control. No dose-finding studies were identified. However, 16 studies assessing pediatric patients who received dexamethasone were included and classified according to the emetogenicity of chemotherapy administered. Eight different total daily dexamethasone doses were administered to patients on day 1 of highly emetogenic chemotherapy: three in conjunction with aprepitant/fosaprepitant plus a 5HT₃ antagonist and five in conjunction with a 5HT₃ antagonist. Five different total daily dexamethasone doses were administered in conjunction with a 5HT₃ antagonist to patients on day 1 of moderately emetogenic chemotherapy. Due to the heterogeneity of studies identified, meta-analysis was not possible. The optimal dexamethasone dose to control acute CIV and to minimize harms in pediatric patients remains uncertain. This is a key area for future research.

Guideline concordant care for prevention of acute chemotherapy-induced nausea and vomiting in children, adolescents, and young adults

PURPOSE

Prescribing guideline-recommended anti-emetics is an effective strategy to prevent CINV. However, the rate of guideline-concordant care is not well-understood. The purpose of this study was to describe the proportion of pediatric, adolescent, and young adult patients receiving HEC or MEC who received guideline-concordant antiemetic prophylaxis for acute CINV and to identify potential predictors of guideline-concordant antiemetic prophylaxis.

METHODS

Using electronic health record data from 2016 through 2018, a retrospective single-institution cohort study was conducted to investigate how often patients less than 26 years of age receiving moderately or highly emetogenic chemotherapy receive guideline-concordant prophylaxis for acute CINV. Guideline-concordant care was defined according to guidelines from the Pediatric Oncology Group of Ontario for patients < 18 years and the American Society of Clinical Oncology for those ≥ 18 years. Independent variables included: sex, age, insurance status, race, ethnicity, cancer type, chemotherapy regimen, clinical setting, chemotherapy emetogenicity, and patient location. Predictors of receiving guideline-concordant care were determined using multiple logistic regression.

RESULTS

Of 180 eligible patients, 65 (36.1%) received guideline-concordant care. In multivariable analysis, being treated in adult oncology setting (aOR 14.3, CI95 5.3-38.6), with a cisplatin-based regimen (aOR 3.5, CI951.4-9.0), solid tumor diagnosis (aOR 2.2, CI95 1.0-4.8), and commercial insurance (aOR 2.4, CI95 1.1-5.2) were associated with significantly higher likelihood of receiving guideline-concordant care.

CONCLUSIONS

Multi-level factors were associated with receiving guideline concordant care for prevention of CINV in children, adolescents, and young adults receiving emetogenic chemotherapy. These findings can inform current efforts to optimize implementation strategies for supportive care guidelines.

Efficacy of Olanzapine for High and Moderate Emetogenic Chemotherapy in Children

This study was conducted to investigate the safety and efficacy of olanzapine for high and moderate emetogenic chemotherapy in children and young adults. We retrospectively reviewed the records of pediatric patients (n = 13) with cancer who had been administered olanzapine as an anti-emetic drug (AED) during a high and moderate emetogenic chemotherapy block from January 2018 to March 2020. Patients were administered other prophylactic AEDs according to practice guidelines. The mean age of the patients was 14.1 ± 5.5 years. The total number of chemotherapy cycles was 41. Twenty-one (51.2%) chemotherapy blocks were high emetogenic chemotherapy and 20 (48.8%) blocks were moderate emetogenic chemotherapy. Olanzapine was used for prophylaxis in 20 (48.8%) blocks of chemotherapy and rescue in 21 (51.2%). Of the 41 cycles, a complete response to olanzapine was achieved in 31 (75.6%), partial response in 6 (14.6%), and no response in 4 (9.8%). The mean dose was 0.07 ± 0.04 mg/kg/dose and 2.50 ± 1.37 mg/m²/dose. Adverse effects included somnolence, hyperglycemia, fatigue, and disturbed sleep. Our findings indicate that olanzapine was effective and safe for treating chemotherapy-induced nausea and vomiting in children. A prospective controlled study is needed to confirm these findings.

Creation of a chemotherapy-induced nausea/vomiting dashboard to improve outcomes for pediatric cancer patients

PURPOSE

Two of the most common acute side effects of chemotherapy are nausea and vomiting. Nausea and vomiting impact quality of life, nutritional status, and ability to tolerate further chemotherapy. Parents of pediatric oncology patients rank nausea as one of the most bothersome treatment-related symptoms.

METHODS

Utilizing Quality Improvement methodology, we developed a dashboard interface to facilitate extraction of data from the electronic medical record (EMR), which is presented via a visual display that summarizes the type of chemotherapy and antiemetic medications, use of as needed medications, and number of episodes of emesis.

RESULTS

This dashboard interface allows for rapid and efficient identification of patients whose antiemetic regimen is mismatched for the emetogenicity of ordered chemotherapy, thus providing a timely opportunity to modify the antiemetic regimen based on published guidelines before administration of chemotherapy drugs. It also allows measurement of the effectiveness of the antiemetic regimen in terms of the number of break through emesis and the need for as needed medications.

CONCLUSIONS

A novel CINV dashboard was created, which visually conveys complex information about antiemetics, chemotherapy emetogenicity, as needed medications, and breakthrough vomiting for inpatient pediatric oncology patients.

Factors Associated With Chemotherapy-Induced Vomiting Control in Pediatric Patients Receiving Moderately or Highly Emetogenic Chemotherapy: A Pooled Analysis

PURPOSE

To identify factors associated with chemotherapy-induced vomiting (CIV) control in pediatric patients receiving highly emetogenic chemotherapy (HEC) or moderately emetogenic chemotherapy (MEC).

MATERIALS AND METHODS

An individual, patient-level, pooled analysis was performed using data from five clinical trials of aprepitant or fosaprepitant in pediatric patients receiving HEC or MEC. The proportion of individuals who experienced no vomiting (complete CIV control) during the phase of interest was the primary study end point. The association of acute-phase complete CIV control (from first chemotherapy dose to 24 hours after the last chemotherapy dose of the chemotherapy block) with age, sex, race, cancer type, acute-phase duration, and antiemetic regimen was examined. Association of the same factors and acute-phase complete CIV control with complete CIV control in the delayed phase (end of acute phase until ≤ 96 hours later) was examined.

RESULTS

A total of 735 patients (mean age, 8.9 years; range, 0.3 to 17.9 years) were included in the acute-phase analysis. Acute-phase complete CIV control was less likely in older patients (relative risk [RR], 0.97 per year; 95% CI, 0.96 to 0.98 per year) and longer acute-phase duration (RR, 0.89 per day; 95% CI, 0.84 to 0.94 per day). Receipt of ondansetron plus aprepitant or fosaprepitant was associated with a higher likelihood of acute-phase complete CIV control versus ondansetron alone (RR, 1.28; 95% CI, 1.09 to 1.50). Delayed-phase complete CIV control was more likely in patients with acute-phase complete CIV control (RR, 1.19; 95% CI, 1.06 to 1.34) and in those who received aprepitant or fosaprepitant.

CONCLUSION

Younger age, shorter acute-phase duration, and antiemetic regimen were associated with acute-phase complete CIV control in pediatric patients receiving HEC or MEC. Acute-phase complete CIV control and antiemetic regimen were associated with delayed-phase complete CIV control.

[Prevention and treatment of antineoplastic drug-induced nausea and vomiting in pediatric onco-hematology: An update]

Antineoplastic drug induced nausea and vomiting are common adverse events in cancer care of paediatric patients ; therefore, prevention and management of these adverse events is a major concern for healthcare professionals. There are common features between paediatric and adult patients in terms of the emetogenic level depending on antineoplastic agents or about available medicines. However, there are also specificities for paediatric population including individual risk factors of emesis or nausea assessment for example. Knowledge relative to available medicines is also limited in the paediatric population, especially for recent medicines. This review aims to provide a comprehensive overview about antiemetics in paediatric oncology to clinicians and other healthcare professionals involved in paediatric cancer care. First of all, we describe physiopathological paediatric specificity, risk factors and clinical assessment of antineoplastic drug induced nausea and vomiting. Secondly, we focus on available medicines and also address the issue of complementary and alternative medicines.

Antiemetic prophylaxis with fosaprepitant and granisetron in pediatric patients undergoing allogeneic hematopoietic stem cell transplantation

Background

Chemotherapy-induced nausea and vomiting (CINV) is a severe and distressing complication during allogeneic hematopoietic stem cell transplantation (alloHSCT). The antiemetic fosaprepitant has shown favorable results in pediatric and adult patients receiving chemotherapy. Data on fosaprepitant in children and adolescents undergoing alloHSCT are missing.

Methods

In this non-interventional observation study, 120 children and adolescents with a median age of 11.8 years undergoing alloHSCT after a moderately or highly emetogenic conditioning (MEC or HEC) were analyzed. They received an antiemetic prophylaxis with granisetron (2 × 40 µg/kg d⁻¹) with or without fosaprepitant (4 mg/kg; single dose, max. 1 × 150 mg/kg BW), and were analyzed in the control (CG; n = 60) or fosaprepitant group (FG; n = 60). The efficacy and safety of the two antiemetic prophylaxis regimens were analyzed and compared with respect to the acute (0–24 h) and the delayed (> 24–120 h) CINV phase and > 120–240 h after MEC or HEC administration.

Results

During MEC, significantly more patients in the CG experienced vomiting during the first 0–24 h (58.6 vs. 25.0%; p = 0.0156) and during > 24–120 h (93.1% vs. 57.1%; p = 0.0020), compared with the FG. Likewise, significantly more vomiting events (269 vs. 136; p < 0.0001) were registered in the CG. During HEC, significantly more patients in the CG experienced vomiting during the first 0–24 h (32.3 vs. 9.4%; p = 0.0319) compared with the FG. Significantly more vomiting events (241 vs. 99; p < 0.0001) were registered in the CG. Laboratory and clinical adverse events were not significantly different between the two groups (p > 0.05).

Conclusions

Antiemetic prophylaxis with fosaprepitant and granisetron was well tolerated, safe, and effective in pediatric patients undergoing alloHSCT. However, larger prospective trials are necessary to evaluate these findings.

Supportive care during pediatric hematopoietic stem cell transplantation: beyond infectious diseases. A report from workshops on supportive care of the Pediatric Diseases Working Party (PDWP) of the European Society for Blood and Marrow Transplantation (EBMT)

Hematopoietic stem cell transplantation (HSCT) is currently the standard of care for many malignant and nonmalignant blood diseases. As several treatment-emerging acute toxicities are expected, optimal supportive measurements critically affect HSCT outcomes. The paucity of good clinical studies in supportive practices gives rise to the establishment of heterogeneous guidelines across the different centers, which hampers direct clinical comparison in multicentric studies. Aiming to harmonize the supportive care provided during the pediatric HSCT in Europe, the Pediatric Diseases Working Party (PDWP) of the European Society for Blood and Marrow Transplantation (EBMT) promoted dedicated workshops during the years 2017 and 2018. The present paper describes the resulting consensus on the management of sinusoidal obstructive syndrome, mucositis, enteral and parenteral nutrition, iron overload, and emesis during HSCT.

Optimizing symptom control in children and adolescents with cancer

There is growing recognition of the degree to which symptoms negatively impact on children receiving cancer treatments. A recent study described that almost all inpatient pediatric oncology patients are experiencing at least one bothersome symptom and almost 60% are experiencing at least one severely bothersome symptom. Poor symptom control occurs because of challenges with communication of bothersome symptoms to clinicians, lack of clinical practice guidelines (CPGs) for most of these symptoms, and failure to administer preventative and therapeutic interventions known to be effective for symptom control. This article reviews approaches used to improve symptom control for children receiving cancer treatments. Areas addressed include systematic symptom screening and creation of CPGs for symptom management. Challenges with electronic health integration are also addressed. Several multi-symptom assessment scales have been developed but none have yet been used to directly influence patient management. The number of CPGs applicable to symptom control in pediatric oncology is increasing but remains small. Improving the creation of and adherence to CPGs for symptom management is an important priority. Finally, identifying ways that symptom management systems can be integrated into clinical work flows is essential; these will likely need to focus on electronic health records.

Systematic review of the effectiveness of complementary and alternative medicine on nausea and vomiting in children with cancer: a study protocol

INTRODUCTION

Nausea and vomiting are two most common symptoms reported by children with cancer when they undergo active treatment. However, pharmacological treatment is not sufficient to manage these two symptoms, with over 40% of children still experience nausea and vomiting after receiving antiemetics. There has been an exponential growth of studies to demonstrate the effectiveness of different complementary complementary medicine (CAM) to control nausea and vomiting during cancer treatment. Appropriate application of CAM enhances the effectiveness of antiemetics, thus reducing the symptom burden on children as well as improving their general condition and quality of life during cancer treatment. Nevertheless, it remains unclear which CAM is the best approach to help children to prevent or reduce nausea and vomiting during and after cancer treatment. This paper describes a protocol for identifying, analysing and synthesising research evidence on the effectiveness of CAM on nausea and vomiting in children with cancer.

METHODS AND ANALYSIS

A total of 10 databases will be searched to identify appropriate literature: MEDLINE, the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, CINAHL, PsycINFO, LILACS, OpenSIGLE, the Chinese Biomedical Literature Database, the Chinese Medical Current Contents and the Chinese National Knowledge Infrastructure. All randomised controlled trials which meet the inclusion criteria will be included. The primary outcome is the changes in nausea and vomiting either assessed by self-reported and/or objective measures. Review Manager 5.3 will be used to synthesise the data, calculate the treatment effects, perform any subgroup analysis and assess the risk of bias.

ETHICAL AND DISSEMINATION

The results will be presented at international conferences and published in peer-reviewed journals. As no individual data will be involved in this review, ethical approval is not required.

Efficacy, Safety And Feasibility Of Antiemetic Prophylaxis With Fosaprepitant, Granisetron And Dexamethasone In Pediatric Patients With Hemato-Oncological Malignancies

Background

Chemotherapy-induced nausea and vomiting (CINV) are a major burden for patients undergoing emetogenic chemotherapy. International guidelines recommend an antiemetic prophylaxis with corticosteroids, 5-HT₃R-antagonists and NK₁R-antagonists. The NK₁R-antagonist fosaprepitant has shown favorable results in pediatric and adult patients. There is little pediatric experience with fosaprepitant.

Methods

This non-interventional observation study analyzed 303 chemotherapy courses administered to 83 pediatric patients with a median age of 9 years (2-17 years), who received antiemetic prophylaxis either with fosaprepitant and granisetron with or without dexamethasone (fosaprepitant group/FG; n=41), or granisetron with or without dexamethasone (control group/CG; n=42), during moderately (CINV risk 30-90%) or highly (CINV risk>90%) emetogenic chemotherapy. The two groups' results were compared with respect to the safety and efficacy of the antiemetic prophylaxis during the acute (0-24hrs after chemotherapy), delayed (>24-120hrs after chemotherapy) and both CINV phases. Laboratory and clinical adverse events were compared between the two cohorts.

Results

Adverse events were not significantly different in the two groups (p>0.05). Significantly fewer vomiting events occurred during antiemetic prophylaxis with fosaprepitant in the acute (23 vs 142 events; p<0.0001) and the delayed (71 vs 255 events; p<0.0001) CINV phase. In the control group, the percentage of chemotherapy courses with vomiting was significantly higher during the acute (24%/FG vs 45%/CG; p<0.0001) and delayed CINV phase (28%/FG vs 47%/CG; p=0.0004). Dimenhydrinate (rescue medication) was administered significantly more often in the CG, compared to the FG (114/FG vs 320/CG doses; p<0.0001). Likewise, in the control group, dimenhydrinate was administered in significantly more (p<0.0001) chemotherapy courses during the acute and delayed CINV phases (79 of 150; 52.7%), compared to the fosaprepitant group (45 of 153; 29.4%).

Conclusion

Antiemetic prophylaxis with fosaprepitant and granisetron with or without dexamethasone was well tolerated, safe and effective in pediatric patients. However, larger prospective trials are needed to evaluate these findings.

Latest Update on Prevention of Acute Chemotherapy-Induced Nausea and Vomiting in Pediatric Cancer Patients

PURPOSE OF REVIEW

Chemotherapy-induced nausea and vomiting (CINV) is a common cause of acute morbidity that impacts quality of life in children receiving cancer treatment. Here, we review the evolution of CINV prophylaxis guidelines in children, with an emphasis on the literature published in the last 5 years, to bring the reader up to date.

RECENT FINDINGS

Recent studies have led to the adoption of the "triple therapy" regimen of antiemetic prophylaxis (a 5-HT3 antagonist, dexamethasone, and a neurokinin-1 antagonist) as the backbone of recommendations for the prevention of CINV in children. Areas of new data include the addition of aprepitant and inclusion of palonosetron as a non-inferior 5-HT3 antagonist. In addition, there are emerging pediatric data informing patient-derived risk factors associated with CINV risk and classification of antineoplastic drugs based on emetogenicity. Several recent pediatric studies have shaped published guidelines for CINV prophylaxis in children.

Acupressure to Reduce Treatment-Related Symptoms for Children With Cancer and Recipients of Hematopoietic Stem Cell Transplant: Protocol for a Randomized Controlled Trial

BACKGROUND

We describe the study design and protocol of a pragmatic randomized controlled trial (RCT) Acupressure for Children in Treatment for a Childhood Cancer (ACT-CC).

OBJECTIVE

To describe the feasibility and effectiveness of an acupressure intervention to decrease treatment-related symptoms in children in treatment for cancer or recipients of a chemotherapy-based hematopoietic stem cell transplant (HSCT).

DESIGN

Two-armed RCTs with enrollment of 5 to 30 study days.

SETTING

Two pediatric teaching hospitals.

PATIENTS

Eighty-five children receiving cancer treatment or a chemotherapy-based HSCT each with 1 parent or caregiver.

INTERVENTION

Patients are randomized 1:1 to receive either usual care plus daily professional acupressure and caregiver delivered acupressure versus usual care alone for symptom management. Participants receive up to 20 professional treatments.

MAIN OUTCOME

A composite nausea/vomiting measure for the child.

SECONDARY OUTCOMES

Child's nausea, vomiting, pain, fatigue, depression, anxiety, and positive affect.

PARENT OUTCOMES

Depression, anxiety, posttraumatic stress symptoms, caregiver self-efficacy, and positive affect. Feasibility of delivering the semistandardized intervention will be described. Linear mixed models will be used to compare outcomes between arms in children and parents, allowing for variability in diagnosis, treatment, and age.

DISCUSSION

Trial results could help childhood cancer and HSCT treatment centers decide about the regular inclusion of trained acupressure providers to support symptom management.

Chemotherapy-induced nausea and vomiting control in pediatric patients receiving ifosfamide plus etoposide: a prospective, observational study

PURPOSE

Little evidence exists regarding the emetogenicity of chemotherapy in pediatric patients. This study describes the prevalence of chemotherapy-induced nausea and vomiting (CINV) in pediatric patients receiving etoposide plus ifosfamide over 5 days, a common pediatric regimen.

METHODS

English-speaking, non-chemotherapy-naïve patients aged 4 to 18 years about to receive etoposide 100 mg/m²/day plus ifosfamide 1800 mg/m²/day over 5 days participated. Antiemetic prophylaxis was determined by each patient's care team. Emetic episodes were recorded and nausea severity was assessed by patients beginning with the first chemotherapy dose, continuing until 24 h after the last chemotherapy dose (acute phase) and ending 7 days later (delayed phase). The proportion of patients experiencing complete acute CINV control (no nausea, no vomiting, and no retching), the primary study endpoint, was described. The prevalence of complete chemotherapy-induced vomiting (CIV) and chemotherapy-induced nausea (CIN) during the acute, delayed, and overall (acute plus delayed) phases; complete delayed and overall CINV control; and anticipatory CINV were also determined.

RESULTS

Twenty-four patients participated; acute CINV was evaluable in 22. Most (75%; 18/24) received a 5-HT3 antagonist plus dexamethasone for antiemetic prophylaxis. Few (23%; 5/22) experienced complete acute CINV control. Complete acute CIV and CIN control were experienced by 57% (13/23) and 27% (6/22) of patients, respectively. Complete delayed CINV, CIV, and CIN control rates were 42% (8/19), 70% (14/20), and 42% (8/19), respectively.

CONCLUSIONS

Our findings support the classification of etoposide 100 mg/m²/day plus ifosfamide 1800 mg/m²/day IV over 5 days as highly emetogenic. This information will optimize antiemetic prophylaxis selection and CINV control in pediatric patients.

Classification of the acute emetogenicity of chemotherapy in pediatric patients: A clinical practice guideline

This clinical practice guideline (CPG) provides clinicians with recommendations regarding chemotherapy emetogenicity classification in pediatric oncology patients. This information is critically important for the appropriate selection of antiemetic prophylaxis. Recommendations are based on a systematic review limited to pediatric patients and a framework for classification when antiemetic prophylaxis is provided. Findings of 87 publications informed the emetogenicity classification of 49 single-agent and 13 combination-agent regimens. Information required for the classification of many chemotherapies commonly administered to pediatric patients is lacking. In the absence of pediatric data, consultation of methodologically sound CPGs aimed at adult oncology patients may be appropriate.

Single center experience on efficacy and safety of Aprepitant for preventing chemotherapy-induced nausea and vomiting (CINV) in pediatric Hodgkin Lymphoma

Chemotherapy-induced nausea and vomiting (CINV) is a distressing treatment side-effect that could negatively affect children's quality of life (QoL). Different scoring systems for CINV were applied and different antiemetic drugs were used; however, few studies have been performed in children undergoing chemotherapy with Aprepitant. Herein, we report a pediatric experience on efficacy and safety of Aprepitant as part of triple antiemetic prophylaxis, in a cohort of thirty-two children and adolescents with Hodgkin Lymphoma (HL), treated with moderate/highly emetogenic chemotherapy (MEC/HEC) regimens in a single Hemato-Oncology Institution. The triple therapy was compared to standard antiemetic therapy in a cohort of twenty-three HL patients (control group). Aprepitant therapy was associated to a significant decrease of chemotherapy-induced vomiting (p = 0.0001), while no impact on the reduction of nausea was observed; these observations were also confirmed by multivariate analysis (p = 0.0040). Aprepitant was well tolerated and the most commonly reported adverse events were neutropenia and hypertransaminasemia. No significant differences on the toxicity were observed between the two compared groups. Our experience on Aprepitant efficacy and safety, associated with feasibility of orally administration, suggests a possible widespread use of the drug to prevent pediatric CINV.

Antiemetic Drug Use in Children: What the Clinician Needs to Know

Vomiting is not only unpleasant for both children and families, but can lead to frequent hospital admission. The persistent vomiting hampers oral intake and increases the risk of dehydration, so the proper use of antiemetic drugs can be useful. The pharmacological treatment of vomiting in children remains a challenge for the pediatrician because several antiemetics are prescribed as "off-label," outside their authorized drug label. Domperidone and ondansetron are the most commonly known antiemetic drugs. A single oral dose of ondansetron has been shown to reduce the risk of recurrent vomiting, the need for intravenous fluids, and hospital admissions in children with acute gastroenteritis. There is enough evidence to support ondansetron administration in children, so the clinical use can be defined as "off-label/on evidence." This review aims to provide an overview of therapeutic use, safety, and main pharmacological properties of antiemetic drugs in children. A comprehensive search of published literature using the PubMed MEDLINE database was carried out to identify all articles published in English from 1998 to February 2018. At present time, the "off-label/on-evidence" use of some antiemetics could improve the success rate of oral rehydration therapy in pediatric emergency settings and to change the management of vomiting with the prevention of the complications.

Adherence to pediatric acute chemotherapy-induced nausea and vomiting guidelines in Canadian hospitals

BACKGROUND

Chemotherapy-induced nausea and vomiting (CINV) impacts quality of life for patients. Guidelines for emetogenicity classification and prevention of CINV in children were recently published and endorsed by pediatric oncology organizations.

PROCEDURE

A multicenter chart review was performed at four Canadian pediatric oncology centers examining rates of prescribing adherence to CINV guidelines between January 2012 and December 2015. Eligible patients received their first chemotherapy course of highly emetogenic chemotherapy (HEC) or moderately emetogenic chemotherapy (MEC).

RESULTS

Guideline adherence was described in 204 patients as antiemetic-only guideline adherence (AGA; examined medication/class prescribed only) and complete guideline adherence (CGA; examined medication/class, dose, frequency, and duration prescribed). Adherence was 29% (HEC 30%, MEC 19%, P = 0.1) and 2% for AGA and CGA patients, respectively. Vomiting in the first 24 h was experienced by 24% of AGA and 34% of non-AGA patients (P = 0.13), with mean breakthrough medication doses similar between AGA and non-AGA groups (HEC 1.8 vs 1.5, P = 0.45; MEC 3 vs 1.42, P = 0.35). In the first 24 h, HEC AGA patients achieved a complete control rate of 37% vs 45% for non-AGA patients (P = 0.31), while patients receiving AGA therapy for MEC achieved a complete control rate of 80% vs 24% for non-AGA patients (P = 0.02).

CONCLUSIONS

Adherence to guidelines was low across all four pediatric institutions. Each center used different approaches to implement pediatric CINV guidelines. Complete CINV control was low, with reports of emesis high, indicating that patients are not receiving optimal treatment.

Identifying clinical practice guidelines for the supportive care of children with cancer: A report from the Children's Oncology Group

Providing evidence-based supportive care for children with cancer has the potential to optimize treatment outcomes and improve quality of life. The Children's Oncology Group (COG) Supportive Care Guidelines Subcommittee conducted a systematic review to identify current supportive care clinical practice guidelines (CPGs) relevant to childhood cancer or pediatric hematopoietic stem cell transplant. Only 22 papers met the 2011 Institute of Medicine criteria to be considered a CPG. The results highlight the paucity of CPGs available to pediatric oncology healthcare professionals and the pressing need to create CPGs using current methodological standards.

Revised antiemetics guidelines and the impact on nutritional status during induction chemotherapy in children with high-risk neuroblastoma

BACKGROUND

High-risk neuroblastoma (HR NBL) treatment requires intensive induction chemotherapy. The profoundly emetogenic agents used can compromise nutritional status. Our institution introduced a new antiemetic guideline in 2010 incorporating regular dexamethasone, in addition to ondansetron, for all highly emetogenic protocols.

PROCEDURE

A retrospective comparative review of pediatric patients diagnosed with HR NBL who received rapid COJEC induction chemotherapy as per HR-SIOPEN NBL trial. Prophylactic antiemetics were prescribed regardless of chemotherapy emetogenicity in group A (2004-2010) but for defined time periods considering chemotherapy emetogenicity in group B (2010-2017).

RESULTS

Sixty-three children were eligible for inclusion (median age, 31 months; range, 1-88 months). Group A had more episodes of emesis than group B (189 vs. 116, P < 0.0001). There was a significant difference in weight-for-age Z score change between the groups by induction end (P = 0.0027). Four children (13%) in group A lost >10% body weight versus none in group B. Nutrition support (NS) was utilized by 29 children (94%) in group A and 22 children (69%) in group B. Group A had a median of 3 (range, 1-7) admissions for febrile neutropenia (FN) versus a median of 1.5 (range, 0-4) for group B (P = 0.003) during induction.

CONCLUSION

The review of our guidelines led to reduced emesis frequency for group B. They also required less NS, followed expected growth trajectories more closely and had fewer FN admissions. We propose that this may have occurred due to better emesis control resulting in improved nutritional status and associated enhanced immune function.

Safety and efficacy of nabilone for acute chemotherapy-induced vomiting prophylaxis in pediatric patients: A multicenter, retrospective review

OBJECTIVES

To describe the safety and efficacy of nabilone given to pediatric patients to prevent acute chemotherapy-induced nausea and vomiting (CINV).

METHODS

A multicenter, retrospective review of pediatric patients who received nabilone for acute CINV prophylaxis between December 1, 2010 and August 1, 2015 was undertaken. One course of nabilone was evaluated per patient. Adverse effects associated with nabilone use were noted. The proportion of patients who experienced complete acute chemotherapy-induced vomiting (CIV) control during the acute phase was determined. The acute phase was defined as starting with the first chemotherapy dose and continuing until 24 h after administration of the last chemotherapy dose of the chemotherapy block.

RESULTS

One hundred ten eligible patients (median age: 14.0 years, range: 1.1-18.0 years; 65 male) were identified. Most (109/110) received nabilone plus a 5-HT3 antagonist for CINV prophylaxis. Adverse effects associated with nabilone were experienced by 34% (37/110) of children. All were of CTCAE Version 4.03 Grade 2 or less. Sedation (20.0%), dizziness (10.0%), and euphoria (3.6%) were the most commonly reported adverse events. Nabilone was discontinued in 10 patients due to an adverse event. The proportions of patients receiving highly or moderately emetogenic chemotherapy who experienced complete acute CIV control were 50.6% (42/83) and 53.8% (14/26), respectively.

CONCLUSION

Adverse events associated with nabilone were common but of minor clinical significance. Acute CIV control in children receiving nabilone as a part of their antiemetic regimen was poor. Future work should focus on implementation of guideline-consistent CINV prophylaxis and treatment.

Evaluation of the Use of Fosaprepitant for the Prevention of Chemotherapy-induced Nausea and Vomiting in Pediatric Patients

A neurokinin-1 (NK1) receptor antagonist is recommended with a 5-HT3 receptor antagonist and dexamethasone for prevention of chemotherapy-induced nausea and vomiting (CINV) in adult patients receiving highly emetogenic chemotherapy. Data for fosaprepitant use in pediatric patients is lacking. A retrospective chart review was conducted using an electronic medical record to characterize the use of fosaprepitant in patients aged 10 months to 18 years at a single institution from August 2015 to January 2017. Thirty-nine patients received fosaprepitant 4 mg/kg (maximum, 150 mg) for prevention of CINV, and 35 were included in the analysis. Ten patients 5 years of age or older who received fosaprepitant after October 2016 were eligible for a follow-up phone call to assess control of delayed CINV. Complete control of emesis was observed in 89% of patients during the acute phase, 63% during the delayed phase, and 60% overall. Overall incidence of nausea as documented in the medical record was 43%. Among the 10 patients who completed follow-up phone calls, 30% experienced emesis and 50% experienced nausea after discharge. Fosaprepitant may be safe and effective in the prevention of CINV in pediatric patients as young as 10 months of age.

Doxorubicin-Induced Myocardial Fibrosis Involves the Neurokinin-1 Receptor and Direct Effects on Cardiac Fibroblasts

BACKGROUND

Cancer patients receiving anthracycline-based chemotherapy (Anth-bC) may experience early cardiac fibrosis, which could be an important contributing mechanism to the development of impaired left ventricular (LV) function. Substance P, a neuropeptide that predominantly acts via the neurokinin 1 receptor (NK-1R), contributes to adverse myocardial remodelling and fibrosis in other cardiomyopathies. We sought to determine if NK-1R blockade is effective against doxorubicin (Dox - a frequently used Anth-bC)-induced cardiac fibrosis and cardiomyocyte apoptosis. In addition, we explored the direct effects of Dox on cardiac fibroblasts.

METHODS

Male Sprague-Dawley rats were randomised to receive saline, six cycles of Dox (1.5mg Dox/kg/cycle) or Dox with an NK-1R antagonist (L732138, 5mg/kg/daily through Dox treatment). At 8 weeks after the initial dose of Dox, LV function and histopathological myocardial fibrosis and cell apoptosis were assessed. Collagen secretion was measured in vitro to test direct Dox activation of cardiac fibroblasts.

RESULTS

Rats undergoing Dox treatment (9mg/kg cumulative dose) developed cardiac fibrosis and cardiomyocyte apoptosis. NK-1R blockade partially mitigated cardiac fibrosis while completely preventing cardiomyocyte apoptosis. This resulted in improved diastolic function. Furthermore, we found that Dox had direct effects on cardiac fibroblasts to cause increased collagen production and enhanced cell survival.

CONCLUSIONS

This study demonstrates that cardiac fibrosis induced by Anth-bC can be reduced by NK-1R blockade. The residual fibrotic response is likely due to direct Dox effects on cardiac fibroblasts to produce collagen.

Safety of Dexamethasone for Nausea and Vomiting Prophylaxis in Children Receiving Hematopoietic Stem Cell Transplantation

BACKGROUND

Many children undergoing hematopoietic stem cell transplantation (HSCT) experience chemotherapy-induced nausea and vomiting (CINV) despite receiving prophylaxis. Guideline-consistent CINV prophylaxis includes dexamethasone, but uncertainty with regard to safety potentially limits the use of dexamethasone in children. We describe immediate adverse events (AEs) attributable to dexamethasone given for CINV prophylaxis to children during HSCT conditioning.

MATERIALS AND METHODS

Children enrolled in a previous prospective study were retrospectively analyzed. Objective parameters related to specific AEs occurring within 5 days of dexamethasone administration were abstracted from health records and graded according to the Common Terminology Criteria for Adverse Events version 4.03 (CTCAE v4.03). Their association to dexamethasone was assessed using the Liverpool Causality Assessment Tool.

RESULTS

Forty-six children (median age, 10.2 y) were eligible for analysis. The most frequent AEs attributable to dexamethasone (Liverpool Causality Assessment Tool category of probable or definite) were hyperglycemia (63%; CTCAE v4.03 grade 3: 2%), hypertension (52%; CTCAE v4.03 grade 3: 15%), and bradycardia (46%; CTCAE v4.03 grade 3: 0%). Other AEs included dyspepsia or gastroesophageal reflux disease (24%) and alterations in mood and behavior (9%). No AE exceeded CTCAE v4.03 grade 3 in severity.

CONCLUSIONS

In children undergoing HSCT who received dexamethasone for CINV prophylaxis, immediate AEs attributable to dexamethasone were most often of minor clinical importance and transient.
