Validation and psychometric assessment of a short clinical scale to measure chemotherapy-induced nausea and vomiting: the MASCC antiemesis tool

Proton pump inhibition to prevent delayed chemotherapy-induced nausea and vomiting in patients receiving adjuvant or neoadjuvant breast cancer chemotherapy: a phase II, randomised double-blind crossover trial (PantoCIN)

PURPOSE

Delayed chemotherapy-induced nausea and vomiting (CINV) is a distressing effect of chemotherapy for early breast cancer (EBC), with rates exceeding 50%, despite multi-agent prophylaxis. We hypothesised that chemotherapy-induced alterations to the gastric environment may result in delayed CINV, and that pantoprazole, a proton pump inhibitor, may be effective prophylaxis by reducing stomach acid.

METHODS

Using a randomised crossover design, we compared pantoprazole 40 mg once daily with placebo for 5 days at the start of each chemotherapy cycle, in addition to standard antiemetic prophylaxis in previously untreated patients undergoing chemotherapy for EBC. The primary endpoint was complete absence of nausea and vomiting during days 2-5. Secondary endpoints included nausea scores using the MASCC Antiemesis Tool (MAT), number of episodes of vomiting and participant preference over the same period.

RESULTS

One hundred sixty participants were recruited from 10 New Zealand hospitals. There was a complete absence of delayed CINV in 51.4% of participants when taking pantoprazole versus 39.3% when taking placebo (OR = 2.2, 95% CI [1.18 to 4.12], P = 0.01). MAT scores for delayed nausea were significantly lower when participants were taking pantoprazole than when the same participants were taking placebo, P = 0.006. Pantoprazole was also preferred by 50.4% versus 25.2% preferring placebo, with no increase in adverse events.

CONCLUSIONS

Pantoprazole is a cost-effective and safe agent, which reduces rates of delayed nausea and should be considered as prophylaxis in patients undergoing emetogenic chemotherapy.

TRIAL REGISTRATION

The trial is registered in the US National Library of Medicine Clinical Trials Registry (Registration No. NCT03948477).

Risk prediction model for chemotherapy-induced nausea and vomiting in cancer patients: a systematic review

BACKGROUND

Chemotherapy-induced nausea and vomiting increase the healthcare burden and lead to adverse clinical outcomes in cancer patients. Although many risk prediction models for chemotherapy-induced nausea and vomiting have been developed, their methodological quality and applicability remain uncertain.

OBJECTIVES

To systematically review and evaluate existing studies on risk prediction models for chemotherapy-induced nausea and vomiting in cancer patients.

METHODS

PubMed, the Cochrane Library, Embase, Web of science, CINAHL, Scopus, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), Wanfang Database, Chinese Biomedical literature Database (CBM) were systematically searched from inception to October 1, 2024. Studies were appraised critically and data extracted by two authors independently based on the Prediction Model Risk of Bias Assessment Tool (PROBAST) and Data Extraction for Systematic Reviews of Prediction Modeling Studies (CHARMS).

RESULTS

A total of 4195 articles were retrieved, ultimately including 17 studies with 62 models for chemotherapy-induced nausea and vomiting. The sample size of the included studies ranged from 137 to 2215, with areas under the curve ranging from 0.602 to 0.850. In this study, the deep forest model demonstrated strong discrimination and calibration, outperforming conventional machine learning and traditional regression models. The five most important predictors in the deep forest model were creatinine clearance, age, sex, anticipatory nausea and vomiting, and antiemetic regimen. Across all included studies, age, chemotherapy regimens, cycles of chemotherapy, history of alcohol consumption, prior episodes of chemotherapy-induced nausea and vomiting, sleep quality before chemotherapy, sex, antiemetic regimens, history of morning sickness, anticipatory nausea and vomiting, were the most frequently reported predictors. All studies were rated as high risk of bias mainly due to poor reporting of the participants and analysis domains, with high concerns regarding applicability in 9 studies.

CONCLUSION

The research on prediction models for chemotherapy-induced nausea and vomiting model is in its developing stage, with both commonalities and differences in predictors. Despite the overall acceptable performance of chemotherapy-induced nausea and vomiting models, most studies have methodological shortcomings, and few models have been validated. Future studies should refer to the Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or Diagnosis (TRIPOD) guideline for model design, implementation, and reporting. Moreover, studies with larger sample sizes and multicenter external validation are necessary to enhance the robustness of predictive models.

Developing and assessing a vomiting-free ward workflow for gynecological patients receiving chemotherapy

BACKGROUND

Chemotherapy-induced nausea and vomiting (CINV) significantly diminishes the quality of life (QoL) for patients undergoing early and late-stage cancer treatments. Despite preventive antiemetic measures, CINV remains a challenge, with limited response rates. CINV adversely affects not only patients' physical health but also their psychological well-being, social interactions, and treatment adherence.

OBJECTIVE

This study aimed to evaluate the impact of a vomiting-free ward initiative on managing CINV and its effects on the psychological well-being and QoL of gynecological cancer patients receiving chemotherapy.

METHOD

In this study, 960 gynecological oncology patients receiving inpatient chemotherapy at a premier obstetrics and gynecology hospital in Sichuan Province were enrolled from January to December 2023. They were evenly divided into intervention and control groups based on their admission dates. Both groups underwent standard care, and the intervention group followed a vomiting-free ward protocol. The effectiveness of this specialized ward was evaluated using the Multinational Association of Supportive Care in Cancer (MASCC) Antiemesis Tool, the Functional Living Index-Emesis (FLIE), and the Hospital Anxiety and Depression Scale (HADS).

RESULTS

The intervention group showed significant improvements in the frequency and severity of both acute and delayed CINV compared to the control group. Furthermore, there was a 9.7% and 7.2% decrease in the impact of severe nausea and vomiting on leisure activities and a 6.9% and 8.6% reduction in how moderate to severe nausea and vomiting affected daily living, respectively. The introduction of the vomiting-free ward significantly reduced levels of patient anxiety (t = - 3.148, P < 0.001) and depression (t = - 3.223, P < 0.001) compared to standard care.

CONCLUSION

The implementation of a vomiting-free ward effectively mitigates nausea and vomiting, enhances QoL, and decreases anxiety and depression among gynecological oncology patients. This innovative approach can be integrated into clinical practice, providing valuable insights and guidelines for healthcare professionals.

Auriculotherapy may help to reduce gastrointestinal reactions and improve quality of life post chemotherapy

AIM

To compare the effectiveness of auriculotherapy in managing nausea and vomiting caused by platinum-based chemotherapy METHODS: 96 patients with gastrointestinal cancer undergoing platinum chemotherapy were randomly divided into three groups, with 32 patients in each group. The control group received conventional treatment, including 5-hydroxytryptamine 3 receptor antagonist and routine nursing care; the remaining two groups received additional auricular point sticking or ear scraping. The outcomes measured included the incidence and frequency of acute and delayed nausea and vomiting, severity of nausea, appetite, and quality of life function index 24 h and 5 d post chemotherapy.

RESULTS

Statistically significant differences were observed in the incidence and frequency of acute and delayed nausea and vomiting, severity of nausea, appetite, and life function index of nausea and vomiting at 24 h and 5 d post chemotherapy (P < 0.05); the efficacy of treatment in the ear scraping and auricular point sticking groups was better than that of the control group (P < 0.05). Moreover, the ear scraping group experienced a more effective reduction in acute nausea and vomiting than that in the auricular point sticking group (P < 0.05), and auricular point sticking showed better results in managing delayed nausea and vomiting and improving appetite and quality of life 5 d post chemotherapy (P < 0.05).

CONCLUSIONS

Auricular point sticking and ear scraping effectively treat chemotherapy-induced nausea and vomiting (CINV). Ear scraping is more effective for acute CINV, whereas auricular point sticking is more effective for delayed CINV, with the distinct advantages of enhancing appetite and quality of life for each type of CINV.

Addition of an NK1 receptor antagonist to standard antiemetic prophylaxis in patients with B-cell lymphoma receiving EPOCH

INTRODUCTION

Data on the optimal management of patients with hematologic malignancies and chemotherapy-induced nausea and vomiting (CINV) are lacking, particularly for multiday chemotherapy regimens. We report our institutional experience in patients with B-cell lymphoma receiving multiday dose-adjusted R-EPOCH chemotherapy utilizing two CINV prophylaxis strategies.

METHODS

We performed a retrospective, single-center, cohort study evaluating hospitalized patients with aggressive non-Hodgkin B-cell lymphoma receiving DA-R-EPOCH (April 2016 to October 2022). All patients received prophylactic corticosteroid and 5HT3-receptor antagonist, and were categorized by the addition of an NK1 receptor antagonist (NK1RA) or not. The primary outcome was complete response (CR, no vomiting, and no rescue medication use) over 120 h. Secondary outcomes included as-needed antiemetic use (acute, delayed, and overall phases), CR without escalating prophylactic antiemetics in cycle 2, and complete control. We performed a descriptive analysis and multivariate logistic regression for NK1RA use, adjusting for age and sex.

RESULTS

Of 128 patients, 56 (43.8%) received an NK1RA as part of their antiemetic regimen, and 72 (56.3%) did not. No patients received prophylactic olanzapine. CR was achieved in 32 (57.1%) of those who received an NK1RA and 30 (41.7%) who did not (OR 0.45; 95% CI, 0.21-0.96; p = 0.039). We observed trends between groups in as-needed antiemetics use (29 [51.8%] vs. 49 [68.1%]; p = 0.061), with most use in the delayed phase (22 [39.3%] vs. 37 [51.4%], p = 0.173). We found no difference in healthcare utilization between the first and second cycle.

CONCLUSION

CINV control in patients with non-Hodgkin B-cell lymphoma receiving DA-R-EPOCH in the hospital was suboptimal. These data support the need to optimize prophylactic antiemetic regimens for patients receiving DA-R-EPOCH.

Auriculotherapy and acupuncture treatments for chemotherapy-induced nausea and vomiting: a multicenter clinical trial

PURPOSE

Nausea and vomiting complicating chemotherapy (CINV) remain side effects despite preventive and curative treatments. We hypothesize that acupuncture (ACU), auriculotherapy (AUR), and their combination (ACU-AUR), could decrease, compared to usual treatment (UT), the intensity of acute nausea in patients already treated according to the antiemetic guidelines and presenting nausea with or without vomiting in the earlier cycle.

METHODS

In this multicenter study, patients were treated just before chemotherapy according to randomization. ACU consisted of implanting bilaterally on each forearm, one semi-permanent needle at point P6. AUR consisted of implanting bilaterally on each pavilion of the ear, one semi-permanent needle at point O. All patients received systematic preventive drug treatment according to antiemetic guidelines. Main outcome was intensity of nausea at 24 h after chemotherapy using a numeric scale ranging from 0 (no nausea) to 10 (maximum symptoms).

RESULTS

One hundred and fifteen patients were included. Baseline characteristics were similar between groups at inclusion. Intensity of nausea at 24 h after chemotherapy, was statistically different between the groups (covariance intergroup analysis, p = 0.005) and was significantly lower for the all-treatment groups vs UT group (p = 0.007 for AUR, p = 0.008 for ACU, and p = 0.0009 for AUR-ACU). AUR-ACU also decreased intensity of delayed nausea when compared to UT (p = 0.023). AUR, ACU and AUR-ACU had no effect on acute and delayed vomiting episodes. No serious adverse event due to the studied treatments was reported in our study.

CONCLUSION

AUR or ACU reduce intensity of acute and delayed nausea in patients treated by optimal antiemetic treatment.

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.

MASCC 2023 Patient-Centered Antiemetic Guidelines and Education Statements: an evidence-based and consensus resource for patients

PURPOSE

The Multinational Association of Supportive Care in Cancer (MASCC)/European Society of Medical Oncology (ESMO) Patient Antiemetic Guideline Committee aimed to (1) adapt the updated evidence-based, clinical guidelines to patient-centered antiemetic guidelines and (2) develop patient education materials and statements.

METHODS

The MASCC 2023 Patient Antiemetic Guidelines were created and reviewed by antiemetic experts and patient advocates by incorporating the 2023 MASCC/ESMO antiemetic guidelines into patient-friendly language. Patient Education Statements were developed based on current literature and by utilizing an expert modified Delphi consensus (≥ 75% agreement). Patient advocate/focus group input and patient survey results were further integrated into Patient-Centered Antiemetic Guidelines and Education Statements.

RESULTS

Patient-Centered Antiemetic Guidelines were created using patient-friendly language and visual slides. Patient-friendly language was also utilized to communicate the Educational Statements. Key content categories identified for the Educational Statements included the following: nausea/vomiting definitions, causes, risk factors, categories, complications, accompanying symptoms, prophylactic antiemetic treatment, general management, when to call/what to ask the healthcare team, what caregivers can do, and available resources. All identified content met the ≥ 75% expert agreement threshold. Fifteen (15) items demonstrated 100% agreement, 11 items achieved ≥ 90% agreement, and three content items demonstrated 80 ~ 82% agreement.

CONCLUSIONS

The inaugural MASCC 2023 Patient Antiemetic Guidelines can help patients and caregivers understand the prevention of nausea and vomiting related to their cancer treatment. Educational Statements provide further patient information. Educating patients on how to utilize guideline antiemetics and the education statements can contribute improvements in the control of anticancer treatment-related nausea and vomiting.

Effect of a Standardized Ginger Root Powder Regimen on Chemotherapy-Induced Nausea and Vomiting: A Multicenter, Double-Blind, Placebo-Controlled Randomized Trial

BACKGROUND

There is substantial interest in the role of ginger as an adjuvant therapy for chemotherapy-induced nausea and vomiting (CINV). However, available evidence lacks robust methodology.

OBJECTIVE

To assess the effect of adjuvant ginger compared with placebo on chemotherapy-induced nausea-related quality of life (QoL) and CINV-related outcomes.

DESIGN

A parallel, double-blind, placebo-controlled randomized trial with 1:1 allocation was conducted.

PARTICIPANTS/SETTING

One hundred three chemotherapy-naïve adults scheduled to receive moderately to highly emetogenic chemotherapy at two hospitals in Australia were enrolled and analyzed.

INTERVENTION

Four standardized ginger capsules (totaling 84 mg/day active gingerols/shogaols), or placebo, were administered commencing the day of chemotherapy and continuing for 5 days for chemotherapy cycles 1 through 3.

MAIN OUTCOME MEASURES

The primary outcome was chemotherapy-induced nausea-related QoL. Secondary outcomes were vomiting- and CINV-related QoL; anticipatory, acute, and delayed nausea and vomiting; fatigue; nutritional status; depression and anxiety; health-related QoL; and adverse events.

STATISTICAL ANALYSES PERFORMED

Intention-to-treat analysis was performed. Mixed analysis of variance with repeated measures determined differences between groups. The null hypothesis was no difference between groups. After applying a Bonferroni multiple testing correction, evidence against the null hypothesis was considered at P= 0.003.

RESULTS

One hundred three participants (ginger: n = 52; placebo: n = 51) were enrolled and analyzed. There was clinically relevant evidence against the null hypothesis, favoring ginger, in change scores for nausea-related QoL (F[df] = 9.34[1,101]; P = 0.003; partial η2 = 0.09), overall CINV-related QoL (F[df] = 12.26[1,101]; P < 0.001; partial η2 = 0.11), delayed nausea severity (F[df] = 9.46[1,101]; P = 0.003; partial η2 = 0.09), and fatigue (F[df] = 10.11[1,101]; P = 0.002; partial η2 = 0.09). There was a clinically meaningful lower incidence of delayed nausea and vomiting in the ginger group at Cycle 2 (53% vs 75%; P = 0.020 and 4% vs 27%; P = 0.001, respectively) and Cycle 3 (49% vs 79%; P = 0.002 and 2% vs 23%; P = 0.001, respectively). There was a clinically meaningful lower incidence of malnutrition in the ginger group at Cycle 3 (18% vs. 41%; P = 0.032) and in change scores for Patient-Generated Subjective Global Assessment (F[df)] = 4.32[1,100]; P = 0.040; partial η2 = 0.04). Change scores between groups favored ginger for vomiting-related QoL and number of vomiting episodes; however, findings were not clinically meaningful. There was no effect of ginger on anticipatory or acute CINV, health-related QoL, anxiety, or depression. No serious adverse events were reported.

CONCLUSIONS

Ginger supplementation was a safe adjuvant to antiemetic medications for CINV that enhanced QoL during chemotherapy treatment. Future trials are needed to examine dose-dependent responses to verify optimal dosing regimens.

Translation and Psychometric Evaluation of the Hindi Language Version of the Pediatric Nausea Assessment Tool (PeNAT) in the Indian Population

OBJECTIVES

To translate the Pediatric Nausea Assessment Tool (PeNAT) into Hindi and validate it in Indian pediatric cancer patients and survivors.

METHODS

The PeNAT-Hindi was finalized by forward and backward translations, and pilot testing. The PeNAT-Hindi was administered to 200 Hindi-speaking pediatric (4-18 y) cancer patients/survivors, in three groups. These included pediatric cancer patients who had recently received chemotherapy (n = 150); who received no chemotherapy within 5 d (n = 25) and survivors (n = 25). Construct validity was tested by comparing scores among the three groups. Test-retest reliability and criterion validity were estimated by the correlation of the first PeNAT score with the second (taken 1 h later) PeNAT score and the number of vomiting/retching episodes, respectively. Convergent validity and discriminant validity were estimated by correlating PeNAT scores with parent-assessed nausea severity, and pain, respectively. The responsiveness was tested by comparing second PeNAT scores with subsequent divergent PeNAT scores among patients reporting subjective change (improvement and worsening, respectively) in nausea severity.

RESULTS

Test-retest reliability of PeNAT-Hindi was good (intraclass correlation = 0.791). The initial PeNAT score had moderate correlation with the number of vomiting/retching episodes (Spearman ρ = 0.401). Median PeNAT scores in group 1 versus groups 2 and 3 were significantly different (p < 0.001). Initial PeNAT scores showed a moderate correlation with parent-assessed nausea (Spearman ρ = 0.657) and a weak correlation with parent-assessed pain (Spearman ρ = 0.319). The responsiveness (standardized response mean) of PeNAT-Hindi to the change in nausea severity was -1.79 (improvement) and 2.19 (worsening), respectively.

CONCLUSION

PeNAT-Hindi showed good reliability and acceptable validity. It may be used among Hindi-speaking children for measuring nausea. The responsiveness of PeNAT-Hindi needs further evaluation.

Effectiveness of antiemetic in reducing chemotherapy-induced nausea and vomiting in adult patients; An oncology center experience

INTRODUCTION

Chemotherapy-induced nausea and vomiting (CINV) are two serious adverse effect of cancer chemotherapy. The objectives of this study are to assess patient satisfaction with antiemetics prescribed, incidence of nausea and vomiting in cancer patients, and the effectiveness of antiemetic regimens in reducing CINV.

METHODS

This is a prospective observational cross-sectional patient survey study, conducted between January and July 2021 in the oncology center at King Saud University Medical City, Riyadh, Saudi Arabia. A suitable, data entry form was designed to collect data including patient demographics, cancer type, antiemetics prescribed, chemotherapy regimen, and incidence of CINV.

RESULTS

The sample comprised 283 cancer patients with a mean age of 47.7 (±14.6) years. Colorectal and breast cancer (n = 67; 23.6%, for each) were the two most common diagnoses. Among the patients who received chemotherapy, most patients (n = 144; 50.8%) received chemotherapy that was classified as highly emetogenic, and 139 (49%) received moderately emetogenic chemotherapy. Antiemetics were given to control CINV before chemotherapy administration (as prophylaxis) were either combination therapy (170 patients (60.0%) received four classes of antiemetics, 72 (25.4%) received three classes; and 31 (10.9%) received two classes) or monotherapy (six patients (2.1%) received one drug). Four patients (1.4%) did not receive any antiemetic medication. Antiemetics given to control CINV after chemotherapy administration (for delayed CINV) were also either in combination (151 patients (53.3%) received three classes of antiemetics and 94 (33.2%) received two classes) or as monotherapy, where 27 patients (9.5%) received one medication. Eleven patients (3.8%) did not receive any antiemetic. The incidence rates for acute and delayed nausea after chemotherapy treatment were 32.1% and 30.7%, respectively; and those for acute and delayed vomiting were 13.4% and 10.2%, respectively. Acute nausea was much more frequent than vomiting.

CONCLUSION

The incidence of CINV was relatively high, and patients who received chemotherapy continued to experience nausea and vomiting despite receiving antiemetic treatment. This demonstrates that antiemetic regimens used are not effective in preventing CINV.

Application of comprehensive unit-based safety program model to improve chemotherapy-induced nausea and vomiting in patients with ovarian cancer: a retrospective study

BACKGROUND

To explore the effect of intervention programs constructed under the guidance of the comprehensive unit-based safety program (CUSP) model on chemotherapy-induced nausea and vomiting (CINV) in patients with ovarian cancer.

METHOD

According to the time of admission, 90 ovarian cancer chemotherapy patients in the first affiliated Hospital of Anhui Medical University from June 2019 to September 2020 were divided into an intervention group and a control group with 45 cases each. Both groups of patients received routine intervention, and the intervention group implemented the CUSP program on this basis. The intervention lasted 8 months. Before and after the intervention, the patients in the ward were used the Multinational Association of Supportive Care in Cancer (MASCC) Antiemesis Tool, the Functional Living Index-Emesis (FLIE), and the Hospital Anxiety and Depression Scale (HADS) for the effect evaluation.

RESULTS

After the intervention, the degree of nausea and vomiting frequency in the intervention group were significantly lower than that in the control group, especially the degree of nausea in the delayed phase (P < 0.05). The score of the functional living index-emesis in the intervention group was significantly higher than that in the control group (P < 0.05), and the anxiety and depression in the intervention group were significantly relieved compared to the control group (P < 0.05).

CONCLUSION

The intervention program guided by the CUSP model can significantly alleviate patients' nausea and vomiting, improve the quality of life, and relieve anxiety and depression. The CUSP model is suitable for clinical practice and has guiding significance for clinical work.

Non-pharmacological management for chemotherapy-induced nausea and vomiting in patients with cancer: a scoping review†

Objective

This review aimed to map and summarize published studies that tested non-pharmacological management for chemotherapy-induced nausea and vomiting (CINV).

Methods

We searched for eligible studies in 5 electronic databases and screened the retrieved studies using the inclusion and exclusion criteria. Data were then collated according to the types of interventions, measurement tool, and outcomes.

Results

The search yielded 2343 records, of which 11 were included. Four categories of non-pharmacological CINV management were made; manipulative and body-based therapy (n = 5 studies); mind–body therapy (n = 3 studies); biologically based practice (n = 1 study), and energy therapy (n = 2 studies). Seven different scales were used to measure CINV. Nine studies reported improvement in CINV.

Conclusions

This scoping review demonstrates the breadth of non-pharmacological management to address CINV. Various types of CINV scales were used to measure CINV severity. The management and scale can be utilized to improve nursing care, particularly in cancer care.

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.

Evidence Summary for Nonpharmacological Management of Chemotherapy-Induced Nausea and Vomiting

Objective. To evaluate and summarize the best evidence for nonpharmacological management of chemotherapy induced nausea and vomiting (CINV). This article aims at serving as a reference for nursing staff to prevent and manage CINV. Methods. We systematically searched for evidence on CINV in databases such as Cnki and Wanfang, guide websites such as GIN and NZGG, and professional websites such as UICC and ACS. Only articles published between November 2012 and November 2021 were considered for inclusion in the summary. Two researchers evaluated the quality of the literature and extracted the data. Results. A total of 22 articles were included in this study, including 3 clinical decisions, 2 guidelines, 1 evidence summary, 2 recommended practices, 13 systematic reviews, and 1 expert consensus. Finally, 15 pieces of evidence were summarized from 3 perspectives: risk factor assessment, nursing process specification, and nonpharmacological interventions. Conclusion. Our research summarizes the best evidence on nonpharmacological management of CINV. During actual clinical application, it is necessary to fully consider the clinical situation, combine professional judgment with patients’ wishes, follow the principle of individualization, analyze the obstacles and facilitating factors of the application of evidence, and prudently apply the evidence to the clinical practice.

Front-line staff perspectives on a caring culture in Chinese hospitals: Validation of a Chinese version of the Culture of Care Barometer

AIMS

The aim of this study is to examine the psychometric properties of the Chinese version of the Culture of Care Barometer in health care organizations.

BACKGROUND

There is a lack of tools to gauge the caring culture in Chinese hospitals. The Culture of Care Barometer is a psychometrically sound measure for caring culture developed in Western settings.

METHODS

This study was guided by Sousa and Rojjanasrira's methodological approach. A total of 2365 staff were recruited from two tertiary hospitals. The Barometer was administered with the Hospital Culture Evaluation Index and Minnesota Satisfaction Questionnaire.

RESULTS

The content validity index was calculated as 0.99. The goodness-of-fit indices, apart from the model chi-square, which was statistically significant, all exceeded established thresholds for adequate fit. The internal consistency was very satisfactory. Pearson's correlation indicated that the tool has good concurrent and convergent validity.

CONCLUSIONS

The Barometer is a reliable and valid instrument to assess front-line staff perspectives on a caring culture in Chinese hospitals.

IMPLICATIONS FOR NURSING MANAGEMENT

Nursing managers can use the Barometer to gauge the caring culture in China. Tailored interventions can be designed to address specific domains, and additional support can be provided to more vulnerable departments or staff groups.

Validation of an Interoperability Framework for Linking mHealth Applications to eRecord Systems in Botswana: Experts’ Survey (Preprint)

BACKGROUND

Electronic record (eRecord) systems and mobile health (mHealth) apps have documented potential to improve health service delivery, resulting in increased global uptake. However, their interoperability remains a global challenge hindering diagnosis, monitoring of health conditions, and data access irrespective of geographic location. Given the widespread use of mobile devices by patients and health care providers, linking mHealth apps and eRecord systems could result in a comprehensive and seamless data exchange within a health care community. The Botswana National eHealth Strategy recognizes interoperability as an issue and mHealth as a potential solution for some health care needs but is silent on how to make mHealth apps interoperable with existing eRecord systems. A literature review and analysis of existing mHealth interoperability frameworks found none suitable for Botswana. As such, it was critical to conceptualize, design, and develop an mHealth-eRecord Interoperability Framework (mHeRIF) to enhance the interoperability pillar of the Botswana National eHealth Strategy and leverage the full benefits of linking mHealth apps with other health information systems.

OBJECTIVE

This study aimed to validate the developed mHeRIF and determine whether it requires further refinement before consideration towards enhancing the National eHealth Strategy.

METHODS

Published framework validation approaches guided the development of a survey administered to 12 purposively selected local and international eHealth experts. In total, 25% (3/12) of the experts were drawn from Botswana, 25% (3/12) were drawn from low- and middle-income countries in sub-Saharan Africa, 25% (3/12) were drawn from low- and middle-income countries outside Africa, and 25% (3/12) were drawn from high-income countries. Quantitative responses were collated in a Microsoft Excel (Microsoft Corp) spreadsheet for descriptive analysis, and the NVivo software (version 11; QSR International) was used to aid the thematic analysis of the qualitative open-ended questions.

RESULTS

The analysis of responses showed overall support for the content and format of the proposed mHeRIF. However, some experts' suggestions led to 4 modest revisions of the mHeRIF.

CONCLUSIONS

Overall, the experts' reviews showed that the mHeRIF could contribute to the National eHealth Strategy by guiding the linking of mHealth apps to existing eRecord systems in Botswana. Similarly, the experts validated an architectural model derived from the mHeRIF in support of the first mobile telemedicine initiative considered for national rollout in Botswana. The mHeRIF helps identify key components to consider before and after linking mHealth apps to eRecord systems and is being considered for use as the foundation of such interoperability in Botswana.

A scoping review of nausea, vomiting and retching measurement methods in children with cancer

Evaluation of chemotherapy-induced nausea and vomiting (CINV) in the pediatric population is subject to diverse approaches. This scoping review summarizes the methods used in clinical studies that assessed nausea, vomiting or retching in children with cancer. We conducted a literature search of studies indexed in EMBASE and Ovid MEDLINE after 2000. Studies were included if they involved patients ≤18 years of age diagnosed with cancer, and had nausea, vomiting or retching as a primary study outcome. We excluded studies that reported only parent- or clinician-proxy measures without including the child's self-reported NVR, and those without specifying the NVR data collection process. The literature search identified twenty-four studies evaluating pediatric nausea, vomiting or retching. In the assessment of NVR, structured surveys were the most commonly used instrument for NVR assessment (75%) and the use of patient diaries (50%). Nine studies (38%) relied solely on self-reports from children as the outcome measure, while fifteen studies (62%) solicited input from parents/ caregivers and healthcare providers in addition to children's self-reports. Almost all the studies reported the frequency (n = 24) and/or severity (n = 23) of NVR symptoms and the use of antiemetic therapy (n = 19). Fewer studies evaluated distress caused by the symptoms (n = 2) and the effects of symptoms on activities of daily living (n = 4). Incorporating NVR measurement tools as part of standard of care for pediatric patients undergoing chemotherapy is strongly advocated. Based on the age group, we recommend the use of such tools comprising Likert scale, pictorial scales and structured scripts to assess various dimensions of a child's NVR experience.

The longitudinal effects of chronotype on chemotherapy-induced nausea and vomiting in patients with breast cancer receiving neoadjuvant chemotherapy

OBJECTIVE

The object of this longitudinal cohort study was to investigate whether chronotype affects the incidence of chemotherapy-induced nausea and vomiting (CINV) among patients with breast cancer.

METHODS

The study included a total of 203 breast cancer patients who received neoadjuvant chemotherapy using a regimen of doxorubicin and cyclophosphamide with high emetogenicity. Patients received four cycles of chemotherapy in approximately three months. Patients completed questionnaires including the Munich Chronotype Questionnaire (MCTQ) before the first chemotherapy and the Multinational Association of Supportive Care in Cancer Antiemesis Tool (MAT) after each of the four chemotherapy sessions. To confirm the effect of chronotype on CINV during the four cycles, we performed statistical analyses using a generalized estimating equation (GEE).

RESULTS

CINV occurred in 108 (53.2%), 112 (55.2%), 102 (50.3%), and 62 (30.5%) patients during four cycles of treatment. In the GEE approach, late and early chronotypes (vs. intermediate chronotype) were associated with an increased risk of CINV (late chronotype: odds ratio [OR], 2.06; 95% confidence interval [CI], 1.41-2.99; p < 0.001, early chronotype: OR, 1.84; CI, 1.25-2.73; p = 0.002), which remained significant even after adjusting for age, BMI, antiemetic treatment, history of nausea and vomiting, anxiety, and sleep quality.

CONCLUSION

Chronotype affected CINV across the four cycles of neoadjuvant chemotherapy in patients with breast cancer, suggesting the need to consider chronotype in predicting and managing CINV.

Effectiveness of Patient-Controlled Intravenous Analgesia (PCIA) with Sufentanil Background Infusion for Post-Cesarean Analgesia: A Randomized Controlled Trial

Purpose

To investigate the effectiveness of sufentanil patient-controlled intravenous analgesia pump (PCIA) and background infusion in patients of post-cesarean analgesia.

Patients and Methods

This trial compared two groups of women undergoing cesarean section and receiving PCIA: no background infusion group (n=30), 6-min lockout time, and background infusion group (n=30), 2 mL/h infusion, 10-min lockout time. Both groups with 2 μg/kg sufentanil was diluted to 100 mL with normal saline. VAS scores at rest at 36 h was the primary endpoint. The secondary endpoints were the VAS scores at rest at 6, 12, and 24 h, the total amount of sufentanil consumed, the Ramsay sedation score (RSS) assessed at the same time points, postpartum bleeding within 24 h, the injection/attempt (I/A) ratio, BP and HR, PONV, side effects of sufentanil.

Results

Compared with the no background infusion group, the background infusion group showed lower VAS pain scores at 6, 12, and 24 h (P<0.01), but no differences at 36 h (95% CI = -0.5-0.8. P>0.05). Attempts, injections, and total sufentanil consumption were significantly different between the two groups (P<0.001), but without difference in I/A. Bleeding was less in the background infusion group at 1 h (P=0.03). The minimal respiration rates were not significantly different between groups.

Conclusion

Background infusion increased the total consumption of sufentanil within 36 h after cesarean section. Although it did not reduce uterine contraction pain and wound pain at 36 h, it significantly reduced the pain at 6, 12, and 24 h after cesarean section. It improved patient satisfaction and reduced the amount of bleeding after 1 h. Importantly, it did not increase the incidence of hypertension, PONV and respiratory depression.

Auricular Acupuncture During Chemotherapy Infusion in Breast Cancer Patients: A Feasibility Study

Introduction: Breast cancer patients undergoing chemotherapy experience multiple distressing symptoms. The authors investigated the feasibility and potential benefits of auricular acupuncture during chemotherapy infusion in this population. Materials and Methods: Women with stage I-III breast cancer undergoing chemotherapy were enrolled and followed for three chemotherapy cycles. During the first cycle of chemotherapy that participants received after study enrollment, they were provided with educational materials. During the second and third cycles of chemotherapy after enrollment, they received auricular acupuncture. The primary outcome was feasibility, assessed by recruitment, retention, and completion of assessments. Secondary outcomes included symptom burden (Edmonton Symptom Assessment System-Revised Version) and anxiety (State-Trait Anxiety Inventory-State), assessed at four timepoints for each cycle: day 1, pre-education/acupuncture (T1); day 1, post-education/acupuncture (T2); day 2 (T3); and day 5 (T4). Nausea and vomiting (Multinational Association of Supportive Care in Cancer [MASCC] Antiemesis Tool) were assessed on days 2 and 5. Paired t test was used to compare patient-reported outcomes during cycle 1 (education) versus an average of outcomes during cycles 2 and 3 (acupuncture). Results: Twenty-six patients were enrolled, of which 24 completed all acupuncture sessions and 22 completed all outcome assessments. In cycles 2 and 3 versus cycle 1, participants experienced significant reductions in symptom burden (change from T1 to T4: -7.9 ± 13.6, p = 0.02), anxiety (change from T1 to T2: -3.3 ± 6.5, p = 0.02), and nausea severity on day 2 (-1.3 ± 2.6, p = 0.04). Conclusions: The delivery of auricular acupuncture during chemotherapy infusion was feasible and associated with reduction of symptom burden, anxiety, and nausea in breast cancer patients. Larger-scale clinical studies are needed to confirm these findings. Clinical Trial Registration number: NCT03170648.

Effect of Acupuncture on Delayed Emesis for the Patients Who Received High-Emetogenic Chemotherapy with Standard Antiemetic Prophylaxis (KHMC-HO-01): An Open-Label, Randomized Study

Background

Chemotherapy-induced nausea and vomiting (CINV) is one of the most important issues associated with chemotherapy. The additional or synergistic effect of acupuncture on CINV remains controversial.

Methods

Patients were randomized into either the group that received standard antiemetics with acupuncture (Arm A) or standard antiemetics only (Arm C). Acupuncture with manual stimulation was applied at eight predefined points and was started before the first cycle of chemotherapy on the first day and two additional sessions were administered on the second day of chemotherapy. Acute and delayed CINV was assessed using the Rhodes Index of Nausea, Vomiting, and Retching (RINVR) and the MASCC Antiemesis Tool (MAT). The primary outcome was the delayed nausea score assessed using the RINVR.

Results

Overall, 42 patients were included. In the delay phase, the severity of delayed nausea was slightly lower without significance in Arm A than in Arm C (5.35 vs. 5.98, p = 0.3011). Similarly, patients in Arm A reported less severe vomiting than those in Arm C (0.75 vs. 1.25, p = 0.3064). Delayed nausea and vomiting assessed by the MAT showed significant relief with acupuncture compared to standard antiemesis alone. In terms of acute emesis, there was no significant difference between the two arms according to either scoring method.

Conclusions

Delayed nausea after HEC tended to decrease with acupuncture using the RINVR score, though it was also not significant. With the MAT assessment, delayed emesis (nausea and vomiting) was significantly improved with acupuncture, suggesting a promising effect of acupuncture. This trial is registered with KCT0006477.

Effects of auricular acupressure on chemotherapy-induced nausea and vomiting in breast cancer patients: a preliminary randomized controlled trial

BACKGROUND

Auricular acupressure (AA) has been viewed as a promising approach to managing chemotherapy-induced nausea and vomiting (CINV) but relevant research evidence has been inconclusive. This study aimed to examine the effects of AA on CINV in breast cancer (BC) patients undergoing chemotherapy.

METHODS

A preliminary randomized controlled trial was conducted in 114 BC patients. Participants were randomly allocated to a true AA group (n = 38), a sham AA group (n = 38), and a standard care group (n = 38). All the participants were provided with standard antiemetic treatment and care, while the true AA group and the sham AA group received an additional 5-day true AA and a 5-day sham AA, respectively. Acute and delayed CINV were assessed by using the MASCC Antiemesis Tool (MAT), anticipatory nausea and vomiting were measured by the Index of Nausea, Vomiting, and Retching (INVR), and patients' quality of life (QoL) was evaluated by the Functional Assessment of Cancer Therapy-Breast (FACT-B).

RESULTS

Both the true and sham AA groups reported improved CINV outcomes than the standard care group, with the true AA demonstrating larger effects than the sham comparison. The true and sham AA groups had higher complete response (CR) rates of CINV when compared with the standard care group, with the difference in the CR of acute CINV achieving statistical significance (p = 0.03). Both the true and sham AA groups demonstrated lower incidence and severity of acute CINV compared with the standard care group with the among-group difference reaching statistical significance for the occurrence (p = 0.04) and severity (p = 0.001) of acute nausea. No significant differences in anticipatory CINV and QoL were found among the groups.

CONCLUSION

The use of AA plus standard antiemetic treatment and care was superior to the use of standard antiemetic treatment and care alone in managing CINV among BC patients receiving chemotherapy. The antiemetic effects of AA were identified to be more profound in improving acute CINV, particularly acute nausea. The antiemetic effects of AA were deemed to be a mixture of specific treatment effects and placebo effects, and the placebo effects were very large and even reached clinical significance.

Multiple Gastrointestinal Symptoms Are Associated With Chemotherapy-Induced Nausea in Patients With Breast Cancer

BACKGROUND

Unrelieved chemotherapy-induced nausea (CIN) is a significant problem for patients with breast cancer (BC).

OBJECTIVE

In a sample of patients with BC who were assessed before their second or third cycle of chemotherapy, study purposes were to evaluate for the occurrence, severity, frequency, and distress associated with CIN; evaluate for differences in demographic and clinical characteristics and gastrointestinal (GI) symptom occurrence rates between patients who did and did not report CIN; and determine which demographic, clinical, and symptom characteristics were associated with the occurrence of CIN.

METHODS

Patients completed demographic and clinical questionnaires and the Memorial Symptom Assessment Scale for nausea and common GI symptom assessments. Univariate analyses evaluated for differences in demographic and clinical characteristics and GI symptom occurrence between patients who did and did not report CIN. Multiple logistic regression analysis evaluated for characteristics associated with CIN.

RESULTS

Of the 532 patients with BC, 47.2% reported CIN occurrence. Characteristics associated with CIN group membership were poorer functional status, receipt of chemotherapy on a 14-day cycle, and higher occurrence rates of 5 GI symptoms (ie, dry mouth, vomiting, constipation, change in the way food tastes, and lack of appetite; all P < .001).

CONCLUSIONS

Unrelieved CIN is a common symptom in patients with BC. This study is the first to demonstrate that 5 co-occurring GI symptoms were associated with CIN occurrence.

IMPLICATIONS FOR PRACTICE

This study identified new risk factors for CIN occurrence in patients with BC. Clinicians may be able to initiate additional interventions to alleviate CIN.

Efficacy and Safety of Adding Olanzapine to the Standard Preventive Regimen for Chemotherapy-induced Nausea and Vomiting in Children: A Randomized Double-blind Controlled Trial

This study aimed to assess the additive value of olanzapine to a combination of ondansetron and dexamethasone to prevent chemotherapy-induced nausea and vomiting (CINV) in pediatric patients. A total of 40 patients between 4 to 18 years of age were enrolled in this randomized clinical trial. Both groups received a combination of ondansetron and dexamethasone, and 0.14 mg/kg olanzapine or matched placebo were administered for olanzapine and control groups, respectively. The primary end points were complete response and lack of nausea as far as three days after chemotherapy evaluated by the Common Terminology Criteria for Adverse Effects (CTCAE) v5.0 and the Multinational Association of Supportive Care in Cancer (MASCC) Anti-emesis Tool (MAT). Side effects of olanzapine were also analyzed. In patients receiving the standard regimen of ondansetron and dexamethasone, nausea was observed in 10.5% and 21% of patients according to MAT and CTCAE scales, respectively. In the olanzapine group, 37.5% (MAT scale) and 31.3% (CTCAE scale) of patients developed nausea. Complete response was observed in 84% (MAT scale) and 94.7% (CTCAE scale) of patients in the placebo group receiving ondansetron and dexamethasone. In comparison, it was observed in 87.5% (MAT scale) and 81.25% (CTCAE scale) for patients allocated to the olanzapine group. Neither acute nor delayed CINV was statistically different between placebo and olanzapine groups. The frequency of adverse effects was higher in the olanzapine group. Adding olanzapine to the standard regimen of CINV prophylaxis was only unhelpful in pediatric patients receiving moderately emetogenic chemotherapy but also associated with a higher rate of minor side effects.

Low-dose olanzapine, sedation and chemotherapy-induced nausea and vomiting: a prospective randomized controlled study

Aims: Comparison of efficacy, safety and sedation between two doses of olanzapine in the control of chemotherapy-induced nausea and vomiting (CINV). Patients & methods: A prospective, randomized, double-blind, controlled study was conducted, enrolling 68 patients receiving a single-day cycle of high and moderately emetogenic chemotherapy. Patients received either of olanzapine 5 mg or 10 mg from day 1 through 3 in addition to ondansetron and dexamethasone. Control of CINV, nausea, sedation, quality of life (QoL) and adverse events were compared. Results: Nausea, emesis control and improvement of QoL were similar in both groups. Sedation severity was 133% higher with 10 mg olanzapine. Conclusions: Lower dose olanzapine is effective to control CINV with significantly reduced sedation.

Chemotherapy-Induced Nausea and Vomiting in Breast Cancer Patients: A Multicenter Prospective Observational Study

Objective:

This study aimed to assess the occurrence of chemotherapy-induced nausea and vomiting (CINV) in acute phase (24 h after chemotherapy) and delayed phase (2–5 days after chemotherapy) after standard antiemetic therapy and to explore the risk factors of CINV in the acute and delayed phases.

Methods:

This prospective and observational study analyzed the data of 400 breast cancer patients scheduled for chemotherapy in two hospitals. The self-report survey was developed to assess the occurrence of CINV and their associated factors. On day 2 and day 6 of chemotherapy, CINV was evaluated by the Multinational Association of Supportive Care in Cancer Antiemetic Tool (MAT). The incidence of acute and delayed CINV was expressed as frequency and percentage.

Results:

Among 400 patients, 29.8% and 23.5% experienced acute and delayed CINV, respectively. Logistic regression analysis showed that the risk factors associated with acute CINV included pain/insomnia, history of CINV, and highly emetogenic chemotherapy. The history of motion sickness (MS), history of CINV, number of chemotherapy cycles completed, and the incidence of acute CINV were significant risk factors for delayed CINV (all P < 0.05).

Conclusions:

The results of this study are helpful for nurses to identify high-risk patients with CINV, formulate effective treatment plans, and reduce the incidence of CINV.

Platinum-induced nausea and vomiting in patients treated for head and neck cancer

INTRODUCTION

Swallowing difficulties in patients with advanced head and neck cancer (HNC) represent an obstacle to adequate antiemetic prophylaxis before chemotherapy. We aim to assess chemotherapy-induced nausea and vomiting (CINV) risk in HNC patients in our center, with a specific focus among patients who could not receive appropriate NK1 receptor antagonist (NK1-RA) prophylaxis.

MATERIALS AND METHODS

Prospective observational monocentric study. CINV were evaluated with the MASCC Antiemesis Tool self-questionnaire (MAT) for all patients treated by platinum-based chemotherapy for advanced HNC (January-April 2019), thereafter, only for patients without NK1-RA prophylaxis due to swallowing difficulties were included (May-October 2019).

RESULTS

Sixty-one patients were included (82% male, 49.2% reccurent/metastatic disease), 18 did not received NK1-RA prophylaxis due to swallowing difficulties. Among 52 patients included from January to April 2019, 17.3% reported swallowing difficulties. The chemotherapy regimen was highly and moderately emetic for 40 (65.6%) and 21 patients (34.4%), respectively. CINV was associated with both cisplatin-based chemotherapy (OR 10.66, 95% CI [2.17-52.08]) and exclusive chemotherapy (OR 7.76, 95% CI [1.79-33.78]). Patients who did not receive anti-NK1 prophylaxis had no more CINV than patients with adequate CINV prophylaxis.

DISCUSSION

CINV remains frequent in patients treated by platinum-based chemotherapy for HNC. Oral NK1-RA prophylaxis can be unavailable because of swallowing difficulties, without an increased risk of CINV.

Data Quality of Chemotherapy-Induced Nausea and Vomiting Documentation

OBJECTIVE

The objective of the study was to characterize the completeness and concordance of the electronic health record (EHR) documentation of cancer symptoms among multidisciplinary health care professionals.

METHODS

We examined the EHRs of children, adolescents, and young adults who received highly emetogenic chemotherapy and characterized the completeness and concordance of chemotherapy-induced nausea and vomiting (CINV) documentation by clinician type and by the International Classification of Diseases 10th Revision (ICD-10) coding choice.

RESULTS

The EHRs of 127 patients, comprising 870 patient notes, were abstracted and reviewed. A CINV assessment was documented by prescribers in 75% of patients, and by nurses in 58% of patients. Of the 60 encounters where both prescribers and nurses documented, 72% agreed on the presence/absence of CINV.

CONCLUSION

Most patients receiving highly emetogenic chemotherapy had a documented assessment of CINV; however, many had incomplete or discordant documentation of CINV from different providers by role, implying the importance of incorporating pragmatic knowledge of EHR documentation patterns among multidisciplinary health professionals for EHR phenotyping and clinical decision support systems directed toward cancer-related symptom management.

Assessing the impact of chemotherapy-induced nausea and vomiting on patients' quality of life: An Arabic version of the Functional Living Index-Emesis

INTRODUCTION

Chemotherapy-induced nausea and vomiting is a serious complication of cancer treatment that compromises patients' quality of life and treatment adherence, which necessitates regular assessment. Therefore, there is a need to assess patient-reported nausea and vomiting using a validated scale among Arabic speaking cancer patient population. The objective of this study was to translate and validate the Functional Living Index-Emesis (FLIE) instrument in Arabic, a patient-reported outcome measure designed to assess the influence of chemotherapy-induced nausea and vomiting on patients' quality of life.

METHODS

Linguistic validation of an Arabic-language version was performed. The instrument was administered to cancer patients undergoing chemotherapy in a tertiary hospital's cancer center in Saudi Arabia.

RESULTS

One-hundred cancer patients who received chemotherapy were enrolled. The participants' mean age was 53.3 ± 14.9 years, and 50% were female. Half of the participants had a history of nausea and vomiting with previous chemotherapy. The Cronbach coefficient alpha for the FLIE was 0.9606 and 0.9736 for nausea and vomiting domains, respectively, which indicated an excellent reliability for the Arabic FLIE. The mean FLIE score was 110.9 ± 23.5, indicating no or minimal impact on daily life (NIDL).

CONCLUSIONS

The Arabic FLIE is a valid and reliable tool among the Arabic-speaking cancer population. Thus, the Arabic version of the FLIE will be a useful tool to assess the quality of life among Arabic speaking patients receiving chemotherapy. Additionally, the translated instrument will be a useful tool for future research studies to explore new antiemetic treatments among cancer patients.

Chemotherapy Remote Care Monitoring Program: Integration of SMS Text Patient-Reported Outcomes in the Electronic Health Record and Pharmacist Intervention for Chemotherapy-Induced Nausea and Vomiting

PURPOSE

Chemotherapy-induced nausea and vomiting (CINV) is a common cause of unplanned healthcare utilization. The University of Michigan Rogel Cancer Center initiated the chemotherapy remote care monitoring program (CRCMP) to proactively identify patients experiencing CINV and intervene before the need for urgent evaluation.

METHODS

High-risk patients for CINV are identified by neurokinin-1 (NK-1) antagonist administration, enrolled in the CRCMP, and received a daily text message survey for 7 days after chemotherapy administration to report symptoms. Responses above a set threshold trigger a message to the team pharmacist for intervention. The primary outcome of 14-day unplanned healthcare use was evaluated before and after CRCMP implementation.

RESULTS

In 8 months, 652 patients received an NK-1 antagonist (2,244 cycles) and 387 patients were enrolled in the CRCMP (59%). Text message response rate was 94%. Clinical pharmacists provided 248 interventions in 121 patient episodes meeting threshold criteria. Fourteen-day unplanned healthcare use was decreased in the CRCMP-enrolled NK-1 episodes (6.68% v 4.53%, P = .02). Admissions were numerically lower for those enrolling in CRCMP when only admissions for nausea were considered (0.63% v 0.35%, P = .33).

CONCLUSION

The CRCMP allowed for real-time management of patient-reported CINV symptom burden based on patient-reported outcomes (PROs) and an electronic medical record-integrated SMS text questionnaire. Clinical pharmacists were key team members to manage patient symptoms. Enrollment in CRCMP significantly reduced overall unplanned healthcare utilization. Although these changes were numerically small, any reduction in unnecessary care utilizing PROs can contribute to high-value care for patients with cancer.

Evaluating the incidence of chemotherapy-induced nausea and vomiting in patients with B-cell lymphoma receiving dose-adjusted EPOCH and rituximab

BACKGROUND

Studies evaluating antiemetic prophylaxis have primarily focused on the solid tumor setting and single-day regimens. This study evaluates antiemetic prophylaxis and chemotherapy induced nausea and vomiting (CINV) in patients with lymphoma receiving a multiday doxorubicin-cyclophosphamide containing regimen.

METHODS

This was a retrospective, single center, cohort study evaluating patients with aggressive non-Hodgkin B-cell lymphoma receiving dose-adjusted R-EPOCH in the hospital. Data was collected from the electronic medical record from April 2016 to September 2019. Complete response over 120 hours was the primary outcome. Secondary outcomes included complete response during the acute and delayed phases as well as complete control.

RESULTS

A total of 73 patients who received dose adjusted R-EPOCH were identified. Most patients (n = 39, 53%) were male with a the median age was 63 years (range: 21-81). Most patients received ondansetron 16 mg once daily (n = 48, 66%) on days 1-5 as antiemetic prophylaxis with a minority receiving either dexamethasone (n = 8) or an NK1 antagonist (n = 13) in addition to ondansetron. Complete response rate was 32% and the complete response in the acute and delayed phase was also 32%.

CONCLUSION

Control of CINV in patients with lymphoma hospitalized to receive dose-adjusted R-EPOCH was suboptimal, with only 32% of patients achieving complete response. Nearly three-quarters of patients received only a 5HT3 receptor antagonist as scheduled antiemetic therapy without an NK1 receptor antagonist. This data supports the importance of improving awareness of regarding multiday CINV guidelines and ensuring timely update and implementation of these evidence-based guidelines.

Breast Cancer Patients' Perceptions of Their Experience With Chemotherapy-Induced Nausea and Vomiting and Its Impact on Quality of Life in Jeddah, Saudi Arabia

Background

Breast cancer accounts for 11.6% of all neoplasms worldwide and is the commonest cancer among Saudi females (29.7%). Chemotherapy-induced nausea and vomiting (CINV) is a very common side effect of chemotherapy that has a great impact on the quality of life (QoL) of patients. Literature is still scarce about this effect on the Saudi population. This study aims to explore breast cancer patients’ perception of their experience with CINV and its impact on QoL.

Methods

This is a cross-sectional retrospective study conducted on Saudi adult female breast cancer patients who underwent chemotherapy at King Abdulaziz Medical City, Jeddah, Saudi Arabia. Data collected through patients’ records review, face-to-face and telephone structured interviews using a questionnaire composed of four parts: sociodemographic characteristics, nature of acute CINV (within 24 hours) and delayed CINV (after 24 hours), impact on QoL, and general information on their experience.

Results

Out of a total population of 173, 98 (56.65%) patients participated in the study. The main findings show that 78.6% experienced nausea, whereas 35.7% experienced vomiting. Most participants had a moderate-to-extreme impact on their QoL due to nausea (74.0%) and vomiting (62.9%). Overall, 57.5% rated anti-emetics as excellent for controlling CINV, whereas 22.9% rated them as moderate to good; 83.5% were completely compliant on anti-emetics and 71.1% reported that they received completely comprehensive education about CINV. Religious practices (74.4%), diet (57.7%), and relaxation techniques (44.9%) were found to be the most common non-pharmacological methods used to control CINV. No significant correlation was found between the effect of CINV on QoL and sociodemographic characteristics (p > 0.05).

Conclusions

CINV is very common among Saudi adult female breast cancer patients; despite being completely compliant and receiving comprehensive education and effective anti-emetics; CINV still had a high impact on different aspects of QoL. Health care professionals should consider CINV as an issue and should find effective strategies for alleviating patients’ suffering.

Chemotherapy-induced nausea in a sample of gynaecological cancer patients: assessment issues and personal risk factors evaluation

PURPOSE

Chemotherapy-induced nausea (CIN) is a relevant problem for gynaecological cancer patients. The evaluation of CIN is a key aspect in its management, along with the identification of associated risk factors. The objective of the study was to compare different measurements of nausea and to investigate personal risk factors in CIN development.

METHOD

Eighty-one women treated for gynaecological cancers took part. The presence of CIN was evaluated using the MASCC Antiemesis Tool (MAT) and a patient's report to clinicians at the subsequent chemotherapy cycle. Personal risk factors were assessed using the State-Trait Anxiety Inventory and a self-report questionnaire.

RESULTS

The study shows that the agreement between patients' assessment of CIN with MAT and what they referred to clinicians was only moderate for acute nausea (Cohen's Kappa = 0.55; p < 0.001), while good for delayed nausea (Cohen's Kappa = 0.68; p < 0.001). At multiple logistic regression analysis, younger age, anticipatory nausea, patient medium-high expectations of CIN, and parity emerged as risk factors for the development of acute nausea (p = 0.0087, 0.0080, 0.0122 and 0.0021, respectively). Patient medium-high expectations of CIN and being single resulted to be risk factors for delayed nausea (p = 0.0397 and 0.0024, respectively).

CONCLUSIONS

Our findings confirm that personal factors contribute to individual differences in the development of CIN; moreover, we highlight the importance of CIN evaluation by clinicians, underlining the need to use reliable instruments.

Management of nausea and vomiting from poly(ADP-ribose) polymerase inhibitor therapy for advanced ovarian cancer

Poly(ADP-ribose) polymerase (PARP) inhibitors have rapidly emerged as a new class of daily oral chemotherapeutic agents that have the potential to dramatically alter the way in which primary peritoneal, fallopian tube and ovarian cancers are treated. However, the management of nausea and vomiting, the most common toxicities incurred by these agents, remains poorly understood. The purpose of this review is to provide an overview of current guidelines, antiemetic agents and management steps for patients experiencing nausea and vomiting associated with the use of PARP inhibitors.

Exploring the nausea experience among female patients with breast cancer; A pilot interview study

•

Nausea is a complicated symptom to report and measure in clinical trials.

•

Better understanding the nausea experience will improve clinical trial designs.

•

Patients have preferences for symptom definitions and nausea grading scales.

•

Patients experience different intensities of nausea.

•

Describing nausea sub-features like duration, timing and character is difficult.

Introduction

Nausea is a difficult symptom to report and measure in clinical trials. We conducted a pilot interview study to improve our understanding of the nausea experience.

Materials and methods

Female patients with breast cancer that had experienced nausea during radiation therapy and/or chemotherapy underwent semi-structured interviews that focused on patient-defined and standard definitions, preferences for nausea grading scales, and nausea sub-features: intensity, location, timing/duration, character, associated symptoms, precipitating/alleviating factors, impact on quality of life.

Results

10 patients were interviewed. Patients defined nausea more variably than vomiting and retching/dry heaving. An ordinal grading scale with a 0–10 intensity range was preferred over visual-analogue and qualitative scales. Patients had experienced different intensities of nausea and deemed reporting their worst, average and least intensities feasible. High-intensity episodes were deemed more problematic than low-intensity episodes regardless of their duration. The duration and character of nausea were difficult to describe. A range of associated symptoms, precipitating and alleviating factors were documented. Nausea had a detrimental impact on quality of life.

Conclusions

Nausea has a range of subjective and objective features. Our pilot study provided valuable information that will inform the design of a planned larger survey study. Creating an operational clinical trial definition for nausea appears feasible.

Psychometric assessment of the Persian version of short clinical scale to measure chemotherapy-induced nausea and vomiting: the MASCC antiemetic tool

INTRODUCTION AND OBJECTIVE

Managing chemotherapy-induced nausea and vomiting (CINV) in patients with cancer is still a challenge for the patients and also the clinicians. The Multinational Association of Supportive Care in Cancer (MASCC) has developed a scale for better measurement and management of CINV. Thus, this paper aims at translating the scale into Persian and assessing the psychometric properties of the proposed translated version of MASCC Antiemesis Tool (MAT).

METHODS

Having received the necessary permissions and complying with the Forward-Backward translation protocol, we conducted a qualitative assessment of the face validity through cognitive interviewing and content validity assess with 5 experts in Persian Literature. Internal consistency using Cronbach's Alpha Coefficient was applied to determine the scale reliability. In order to determine the construct validity, the three methods of exploratory factor analysis, known group analysis, and convergent validity (assessment of the correlation between Rhodes Index of Nausea, Vomiting and Retching (INVR) scale and the Persian version of MAT scale) were conducted on 300 participants.

RESULTS

About 300 patients with a mean age of 50.73 ± 0.81 participated in the study. The results showed a significant difference in the index of nausea and vomiting between the patients who are below 50 years old and those who are above 50 (P = 0.0001). The Cronbach's Alpha Coefficient was reported 0.88 for the whole MAT questionnaire. Due to the low factor load (fewer than 0.5) for question 1, it was removed in the factor analysis. Besides, exploratory factor analysis (EFA) led to the exploration of the two factors of nausea and vomiting.

CONCLUSION

According to the results of the study, the Persian version of the MAT questionnaire is considered as a highly reliable and valid tool, in order to efficiently and accurately measure chemotherapy-induced nausea and vomiting and to better manage this side effect.

Assessment of postoperative nausea and vomiting after bariatric surgery using a validated questionnaire

BACKGROUND

Postoperative nausea and vomiting (PONV) is known to occur after bariatric surgery, with over two thirds of patients affected. However, variability exists in how to objectively measure PONV.

OBJECTIVES

The goals of the present study were to use a validated, patient-centered scoring tool, the Rhodes Index of Nausea, Vomiting, and Retching to measure the severity of PONV after bariatric surgery, to directly compare PONV between patients who underwent laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB), and to identify risk factors for the development of PONV after bariatric surgery.

SETTING

Barnes-Jewish Hospital/Washington University School of Medicine, St. Louis, Missouri, United States of America.

METHODS

The Washington University Weight Loss Surgery team prospectively surveyed patients from January 1, 2017 to December 1, 2018 at the following 6 different timepoints: postoperative day (POD) 0, POD 1, POD 2, POD 3 to 4, the first postoperative outpatient visit (POV 1: POD 5-25), and the second postoperative visit (POV 2: POD 25-50). At each timepoint, a cumulative Rhodes score was calculated from the sum of 8 questions. The American Society for Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database was used to collect patient demographic characteristics and perioperative clinical data.

RESULTS

A total of 274 patients met study criteria and completed 605 Rhodes questionnaires. Two hundred fifty Rhodes questionnaires were completed by patients after SG and 355 were completed by patients after LRYGB. Total Rhodes scores are statistically higher in LSG patients compared with patients who underwent LRYGB (LSG = 5.45 ± 6.27; LRYGB = 3.08 ± 4.19, P = .0002). Additionally, at the earlier timepoints, scores were higher among patients who underwent LSG than those who had undergone LRYGB as follows: POD 0 (LSG = 6.96 ± 6.50; LRYGB = 2.89 ± 2.90, P = .0115), POD 1 (LSG = 8.20 ± 6.76; LRYGB = 2.88 ± 3.44, P < .0001), and POD 2 (LSG = 4.05 ± 4.88; LRYGB = 2.06 ± 3.43, P = .05). On subset analysis, examining patients who either underwent an LSG or LRYGB, both procedures had a statistically significant PONV peak emerge on POV 2. Last, overall Rhodes scores were statistically higher in female patients compared with male patients (female: 4.43 ± 5.46; male: 2.35 ± 3.90, P = .021). Although the magnitude of the difference varied somewhat across POD time intervals, the difference was most pronounced at POV 2.

CONCLUSIONS

This is the largest study using a validated nausea and vomiting questionnaire to objectively measure PONV after bariatric surgery. The factors found to be most associated with increased PONV were LSG and female sex. Ultimately, these data can help bariatric surgery programs, including Washington University Weight Loss Surgery, identify patients who may require more intensive treatment of PONV, particularly POD 0 to 2, and help to identify patients that continue to struggle with PONV in the later surgical recovery phase.

Randomized open-label phase II trial of 5-day aprepitant plus ondansetron compared to ondansetron alone in the prevention of chemotherapy-induced nausea-vomiting (CINV) in glioma patients receiving adjuvant temozolomide

PURPOSE

CINV remains a distressing side effect experienced by glioma patients receiving multi-day temozolomide therapy, in spite of guideline-based antiemetic therapy with selective serotonin-receptor-antagonists. Antiemetic research with aprepitant has routinely excluded glioma patients. In this randomized open-label phase II study, use of a nonstandard 5-day regimen of aprepitant for glioma patients was investigated.

METHODS

One hundred thirty-six glioma patients receiving their first cycle of adjuvant temozolomide (150-200 mg/m2/day × 5 days every 28 days) were randomized to Arm-A (ondansetron 8 mg days 1-5 with aprepitant day 1: 125 mg, days 2-5: 80 mg) or Arm-B (ondansetron). Randomization was stratified by tumor grade and number of prior chemotherapy regimens. The primary endpoint was the percentage of patients achieving complete control (CC), defined as no emetic episode or antiemetic rescue medication over the 7-day study period. Secondary endpoints included CINV efficacy in the acute phase (≤ 24 h) and delayed phase (days 2-7), as well as safety and quality of life (QoL).

RESULTS

Patients were 61% male, 97% white, 48% with KPS > 90%, 60% non-smokers, mean age 54, 92% with low alcohol use, and 46% with a CINV history. The CC was 58.6% (Arm-A) and 54.5% (Arm-B). Acute-complete response (CR) rates, defined as CC on day 1 in Arm-A and -B, were 97.1% and 87.9%, respectively (p = 0.056). Treatment-related toxicities were mild or moderate in severity.

CONCLUSIONS

Aprepitant plus ondansetron may increase acute-CR, may have benefit regarding CINV's effect on QoL, and is safe for 5-day temozolomide compared to ondansetron. This study provides no evidence that aprepitant increases CC rate over ondansetron alone.

Supplemental prophylactic intervention for chemotherapy-induced nausea and emesis (SPICE) trial: Protocol for a multicentre double-blind placebo-controlled randomised trial

AIM

There is significant recent interest in the role of ginger root (Zingiber officinale) as an adjuvant therapy for chemotherapy-induced nausea. The supplemental prophylactic intervention for chemotherapy-induced nausea and emesis (SPICE) trial aims to assess the efficacy by reduced incidence and severity of chemotherapy-induced nausea and vomiting, and enhanced quality of life, safety and cost effectiveness of a standardised adjuvant ginger root supplement in adults undergoing single-day moderate-to-highly emetogenic chemotherapy.

METHODS

Multisite, double-blind, placebo-controlled randomised trial with two parallel arms and 1:1 allocation. The target sample size is n = 300. The intervention comprises four capsules of ginger root (totalling 60 mg of active gingerols/day), commencing the day of chemotherapy and continuing for five days during chemotherapy cycles 1 to 3. The primary outcome is chemotherapy-induced nausea-related quality of life. Secondary outcomes include nutrition status; anticipatory, acute and delayed nausea and vomiting; fatigue; depression and anxiety; global quality of life; health service use and costs; adverse events; and adherence.

RESULTS

During the five-month recruitment period from October 2017 to April 2018 at site A only, a total of n = 33 participants (n = 18 female) have been enrolled in the SPICE trial. Recruitment is expected to commence at Site B in May 2018.

CONCLUSIONS

The trial is designed to meet research gaps and could provide evidence to recommend specific dosing regimens as an adjuvant for chemotherapy-induced nausea and vomiting prevention and management.

Integration of a nausea and vomiting assessment tool into antineoplastic management of pediatric oncology patients

BACKGROUND

Antineoplastic-induced nausea and vomiting (AINV) is a treatment-related issue that can have significant negative influences on the cancer patient's quality of life. Assessment of nausea is challenging in children as few studies include the perception of nausea as an outcome, and the severity is rarely evaluated with the use of a validated instrument. We describe our experience of integrating an AINV tool into patient care at the Alberta Children's Hospital.Procedure: The Pediatric Nausea Assessment Tool (PeNAT) was adapted to create a standardized tool that could be used by the clinical pharmacists for AINV assessment. From February to August 2017, 74 patients receiving 217 cycles of highly or moderately emetogenic chemotherapy (HEC or MEC) were eligible to use the AINV tool. Patients that completed the AINV tool were contacted to complete a satisfaction survey.

RESULTS

AINV tool uptake was low: 47 (22%) eligible chemotherapy cycles utilized the tool (24 (32%) and 23 (16%) cycles of HEC and MEC, respectively, (p < 0.01)). Ifosfamide-containing cycles received the highest nausea ratings, with nausea severity correlated with agent emetogenicity. Mean nausea rating was 2.07 versus 1.76 for patients receiving HEC or MEC, respectively. Clinical pharmacists performed 1.24 AINV interventions per day. Patient satisfaction with AINV care overall was high; however, 51% of patients indicated that the tool led to no changes in nausea symptoms.

CONCLUSIONS

AINV tool uptake was low with limited value in improving outcomes. Incorporation of nausea assessment into the electronic health record and potential use of a mobile application may improve uptake.

Exploring Nurses' Understanding of Anticipatory Nausea and Vomiting in Patients With Cancer

PURPOSE

To explore nurses' self-reported understanding of anticipatory nausea and vomiting (ANV) in patients with cancer.

PARTICIPANTS & SETTING

12 oncology RNs were recruited from University Hospital Limerick in Ireland.

METHODOLOGIC APPROACH

Data were collected via semistructured interviews and analyzed using a qualitative content analysis approach with a focus on the manifest content.

FINDINGS

The following themes were identified.

IMPLICATIONS FOR NURSING

Although oncology nurses may understand the importance of assessing and treating patients on an individual basis throughout the course of treatment, formal ANV assessments are warranted to ensure the implementation of best practice. The findings of the current study can guide oncology nurses' approach to the assessment and management of ANV.

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.

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.

Fixed Combination Antiemetic: A Literature Review on Prevention of Chemotherapy-Induced Nausea and Vomiting Using Netupitant/Palonosetron

BACKGROUND

Prevention of chemotherapy-induced nausea and vomiting (CINV) can be improved with guideline-consistent use of antiemetics. However, adherence to antiemetic guidelines remains often insufficient. Therefore, new strategies that improve adherence are needed.

OBJECTIVES

To review the latest antiemetic guideline recommendations and provide an update on the use of NEPA, a fixed combination antiemetic composed of the neurokinin-1 receptor antagonist (RA) netupitant and the 5-hydroxytryptamine-3 RA palonosetron (Akynzeo®).

METHODS

Analysis of the literature was performed, including guidelines, published literature, congress data on NEPA, and relevant articles on CINV.

FINDINGS

Nurses are in a unique position to promote guideline-consistent antiemetic prophylaxis and are central in the education of patients and caregivers. Thus, nurses’ continuous education on antiemetic treatments is key for the prevention and management of CINV. NEPA offers a simplified antiemetic therapy with the potential to increase guideline adherence.

Preventing chemotherapy-induced nausea and vomiting with netupitant/palonosetron, the first fixed combination antiemetic: current and future perspective

Chemotherapy-induced nausea and vomiting (CINV) can be prevented in most patients receiving appropriate antiemetic treatment. However, inadequate uptake of current antiemetic guideline recommendations by physicians, and poor treatment adherence by patients, lead to suboptimal CINV control. There is an unmet need to optimize guideline-consistent use of antiemetics to improve CINV management and prevention. Herein, we provide an overview of CINV, then discuss oral and intravenous NEPA, the first fixed combination antiemetic, composed of netupitant/fosnetupitant and palonosetron. We describe the main pharmacologic and pharmacokinetic characteristics of NEPA, and review the clinical evidence supporting its use in the prevention of CINV.

Evaluation of aprepitant and fosaprepitant in pediatric patients

BACKGROUND

Single-dose i.v. fosaprepitant has been approved as an alternative to 3 day oral aprepitant, a neurokinin-1 receptor antagonist, and improves prevention of chemotherapy-induced nausea and vomiting (CINV). Because fosaprepitant has shown similar efficacy to aprepitant in adult patients only, this study compared the efficacy and safety of aprepitant and fosaprepitant in pediatric patients.

METHODS

Children younger than 18 years who received aprepitant or fosaprepitant to manage CINV between January 2015 and March 2018 at the National Cancer Center Hospital (Tokyo) were recruited to this study. The primary endpoint was complete response (CR; no vomiting/rescue medication) between 0 and 120 h after the start of chemotherapy. Secondary endpoints were safety based on the frequency of severe adverse events, and evaluation of patient characteristics as risk factors (effect of age and sex).

RESULTS

A total of 125 chemotherapy cycles were evaluated. In the aprepitant group, CR was observed in 36 of 80 treatment cycles (45.0%), whereas in the fosaprepitant group, it was observed in 19 of 45 cycles (42.2%; P = 0.852). No treatment-related severe adverse events were observed in either group. The number of non-CR was greater than that of CR in patients aged 6-14 years. The difference in CR rate between male and female patients was not statistically significant (47.1% vs 40.0%, respectively; P = 0.471).

CONCLUSIONS

Aprepitant and fosaprepitant were safely used and may be equally useful for pediatric patients receiving highly emetogenic chemotherapy. CR rate may be associated with patient age.

Network Analysis of the Multidimensional Symptom Experience of Oncology

Oncology patients undergoing cancer treatment experience an average of fifteen unrelieved symptoms that are highly variable in both their severity and distress. Recent advances in Network Analysis (NA) provide a novel approach to gain insights into the complex nature of co-occurring symptoms and symptom clusters and identify core symptoms. We present findings from the first study that used NA to examine the relationships among 38 common symptoms in a large sample of oncology patients undergoing chemotherapy. Using two different models of Pairwise Markov Random Fields (PMRF), we examined the nature and structure of interactions for three different dimensions of patients’ symptom experience (i.e., occurrence, severity, distress). Findings from this study provide the first direct evidence that the connections between and among symptoms differ depending on the symptom dimension used to create the network. Based on an evaluation of the centrality indices, nausea appears to be a structurally important node in all three networks. Our findings can be used to guide the development of symptom management interventions based on the identification of core symptoms and symptom clusters within a network.

TELENURSING FOR THE CONTROL OF CHEMOTHERAPY-INDUCED NAUSEA AND VOMITING: A RANDOMIZED CLINICAL TRIAL

ABSTRACT Objective: to verify the effectiveness of telenursing in the control of nausea and vomiting induced by antineoplastic chemotherapy. Method: a randomized controlled trial of 61 cancer patients undergoing outpatient chemotherapy treatment, randomized into experimental group and control group. Nausea and vomiting were evaluated by the instrument Multinational Association on Supportive Care in Cancer. The telephone intervention was performed four times after chemotherapy. To verify the effects of this on the variables, the Mann-Whitney test and Student's t-test were used. Wilcoxon signed-rank test was applied to confirm the hypothesis of differences in the pre- and post-test intragroup scores. Results: the groups were homogeneous regarding sociodemographic and clinical characteristics. The experimental group showed a statistically significant reduction in the occurrence of nausea (p=0.0089), in the degree of nausea, in two moments, between 24 hours and three days, and three days and five days (p=0.007 and p=0.009, respectively), in the occurrence of vomiting (p=0.008) and in the number of vomiting episodes (p=0.020). Conclusion: telephone intervention is a potential nursing intervention to reduce nausea and vomiting associated with antineoplastic chemotherapy. Brazilian Clinical Trial Registry: RBR-6s8qm5.
