Management Of Chemotherapy-induced Nausea And Vomiting Research Articles

Comparative effectiveness of netupitant-palonosetron plus dexamethasone versus aprepitant-based regimens in mitigating chemotherapy-induced nausea and vomiting: a meta-analysis of randomized controlled trials.

Despite guidelines for managing chemotherapy-induced nausea and vomiting (CINV), there remains a need to clarify the optimal use of neurokinin-1 (NK1) receptor antagonists. Comparing the effectiveness of NEPA (netupitant-palonosetron) plus dexamethasone with other NK1 antagonist-based regimens combined with a 5HT3 receptor antagonist and dexamethasone is crucial for informed decision-making and improving patient outcomes. We conducted a systematic review of the literature to assess randomized controlled trials (RCTs) comparing the efficacy, safety, and cost-effectiveness of NEPA plus dexamethasone and other NK1 antagonist-based regimens combined with a 5HT3 receptor antagonist and dexamethasone. PubMed, Embase, and the Cochrane Library databases were systematically searched, with the latest update performed in December 2023. Data on patient demographics, chemotherapy regimen characteristics, and outcomes were extracted for meta-analysis using a random-effects model. Seven RCTs were analyzed. NEPA plus dexamethasone showed superior efficacy in achieving complete response in the overall (risk ratio [RR], 1.15; 95% CI, 1.02--1.30) and delayed phases (RR, 1.20; 95% CI, 1.03-1.41) of chemotherapy. It was more effective in controlling nausea (overall phase RR, 1.20; 95% CI, 1.05-1.36; delayed phase RR, 1.21; 95% CI, 1.05-1.40) and reducing rescue therapy use (overall phase RR, 1.45; 95% CI, 1.07-1.95; delayed phase RR, 1.75; 95% CI, 1.10-2.78). Adverse event rates were comparable (RR, 1.03; 95% CI, 0.96-1.10). Subgroup analysis indicated NEPA's particular efficacy in patients receiving moderately emetogenic chemotherapy (RR, 1.31; 95% CI, 1.07-1.60). NEPA plus dexamethasone regimens exhibit superior efficacy in preventing CINV, supporting their preferential inclusion in prophylactic treatment protocols. Its effective symptom control, safety profile, and cost-effectiveness endorse NEPA-based regimens as a beneficial option in CINV management.

Dexamethasone-Sparing Antiemetic Prophylaxis for Chemotherapy-Induced Nausea and Vomiting in Highly and Moderately Emetogenic Chemotherapy: The SHEILD Study.

Chemotherapy-induced nausea and vomiting (CINV) significantly impacts patient's quality of life and treatment adherence. This study investigated the efficacy of Generic Netupitant and Palonosetron tablets (Nykron) with dexamethasone single dose for CINV prophylaxis in patients receiving highly emetogenic chemotherapy (HEC) and moderately emetogenic chemotherapy (MEC).Additionally, this approach aligns with the principles of the SHIELD study (Sparing High Efficacy Intervention for Low Dose Dexamethasone), which focuses on maximizing antiemetic effectiveness while minimizing dexamethasone use. This multicenter retrospective study evaluates data from patients who received HEC/MECand were administered a fixed-dose combination of Generic NEPA (Netupitant 300 mg and Palonosetron 0.5 mg tablets, Nykron combi-pack) along with a single dose of dexamethasone (12 mg/8 mg) before chemotherapy. The data were collected from September 2022 till September 2023. Outcomes measuredincluded complete response (no vomiting and no need for rescue medications), complete protection (no significant nausea (<2.5 cm on VAS), no vomiting, and no use of rescue medication), and complete control (no emetic episodes, no rescue therapy, and no nausea [0 cm on VAS])during the acute phase (0-24 hours) and delayed phase (24-120 hours) post-chemotherapy. The data of 372 patients was evaluated in which breast cancer was the most common cancer with 223 (59.95%) patients for which doxorubicin and cyclophosphamide (192, 51.61%) was the most administered chemotherapy combination. The second most common cancer was gastrointestinal (GI) cancer with stomach cancer in 47 (12.6%), colorectal cancer in 4 (1%), and pancreatic cancer in 2 (0.54%). A total of 360 (96.8%) patients received an HEC regimen across the cycle, while only 5 (1.3%) received an MEC regimen. The regimen demonstrated exceptional efficacy with a 96.9% overall response rate across all cycles. Complete control rates for acute CINV were 92% and 90% for delayed CINV across chemotherapy cycles. Complete response rates remained consistently high (94%-98%) across all cycles and overall phases. Only 3% of patients experienced anticipatory CINV. This dexamethasone-sparing Generic NEPA regimen showed remarkable efficacy in CINV management for HEC/MEC regimen-receiving patients, maintaining high response rates in both acute and delayed across all cycles. These findings indicate a potential paradigm shift in CINV prophylaxis, necessitating further investigation through prospective, randomized controlled trials to validate long-term safety and efficacy.

The influence of psychosocial factors on first-time chemotherapy-induced nausea and vomiting: A prospective multicenter cohort study.

12135 Background: Previous studies have suggested that if cancer patients experience no chemotherapy-induced nausea and vomiting (CINV) or mild symptoms during their first chemotherapy cycle, they are less likely to experience CINV in subsequent cycles, suggesting that the optimal intervention time may be before the first chemotherapy cycle. Consequently, attention should be paid to relevant risk factors. Currently, there is a lack of data on psychosocial risk factors related to chemotherapy among cancer patients in China. Methods: This study was a multicenter, prospective cohort study that included cancer patients from seven hospitals' oncology departments who were scheduled to undergo their first chemotherapy cycle. The chemotherapy regimens administered were either highly or moderately emetogenic protocols. Demographic and baseline clinical characteristics were recorded by clinical oncologists. Participants were asked to complete the Distress Thermometer (DT), the Mini-Mental Adjustment to Cancer (Mini-MAC), and a risk factor questionnaire the day before chemotherapy, and to keep a daily diary describing their CINV experiencing for 21 days after chemotherapy. Results: Between October 2022 and November 2023, a total of 1100 cancer patients were enrolled in this study and 972 cancer patients completed all the questionnaires. A total of 64.1% reported CINV during the first chemotherapy cycle. In logistic regression analysis, CINV was predicted by higher PS score (OR=1.411, p=0.049), highly emetogenic regimens (OR=1.846, p=0.004), failure to follow anti-emetics guidelines (OR=2.323, p&lt;0.001), history of nausea/vomiting for other reasons(OR=1.817, p=0.001), lower number of hours slept before the night of chemotherapy (OR=8.987, p&lt;0.001), expectancy of CINV(OR=1.505, p=0.032), maladaptive coping (OR = 1.03, p = 0.024) and distress (OR = 1.157, p =0.021). Conclusions: Psychosocial factors significantly correlate with chemotherapy-induced nausea and vomiting (CINV) among Chinese cancer patients. These findings underscore the importance of integrating psychosocial assessments into the management of CINV, potentially improving treatment outcomes and patient experiences.

Establishing a nausea-free ward model to reduce chemotherapy-induced nausea and vomiting: A retrospective study.

The objective of this study was to establish a nausea-free ward model and evaluate the effect of an intervention procedure guided by this model on chemotherapy-induced nausea and vomiting (CINV) in cancer patients. A total of 105 chemotherapy patients from March to September 2022 before the establishment of nausea-free ward in the Chongqing Jiulongpo District People's Hospital were selected as the control group as well as 105 chemotherapy patients from March to September 2023 after the establishment of nausea-free ward as the intervention group. The intervention group was managed by comprehensive standardized CINV management on the basis of the control group. Finally, the Chinese Society of Clinical Oncology grading tool for nausea and vomiting and the Functional Living Index-Emesis were used to evaluate the effect. Under the intervention of the nausea-free ward model, the intervention group exhibited significantly lower ratings of nausea and vomiting compared to the control group (all P-value <.05). The nausea score, vomiting score, and total score of the intervention group were significantly lower than the control group (all P-value <.05). Our study found CINV symptoms and quality of life can be significantly improved by the application of the nausea-free ward model. The nausea-free ward model is instructive in clinical practice and can guide clinical work as well as bring management experience to clinical workers.

Gene polymorphisms of TACR1 serve as the potential pharmacogenetic predictors of response to the neurokinin-1 receptor antagonist-based antiemetic regimens: a candidate-gene association study in breast cancer patients.

The current candidate gene association study aims to investigate tag SNPs from the TACR1 gene as pharmacogenetic predictors of response to the antiemetic guidelines-recommended, NK-1 receptor antagonist-based, triple antiemetic regimens. A set of eighteen tag SNPs of TACR1 were genotyped in breast cancer patients receiving anthracycline and cyclophosphamide (with/without docetaxel) applying real-time PCR-HRMA. Data analysis for 121 ultimately enrolled patients was initiated by defining haplotype blocks using PHASE v.2.1. The association of each tag SNP and haplotype alleles with failure to achieve the defined antiemetic regimen efficacy endpoints was tested using PLINK (v.1.9 and v.1.07, respectively) based on the logistic regression, adjusting for the previously known chemotherapy-induced nausea and vomiting (CINV) prognostic factors. All reported p-values were corrected using the permutation test (n = 100,000). Four variants of rs881, rs17010730, rs727156, and rs3755462, as well as haplotypes containing the mentioned variants, were significantly associated with failure to achieve at least one of the defined efficacy endpoints. Variant annotation via in-silico studies revealed that the non-seed sequence variant, rs881, is located in the miRNA (hsa-miR-613) binding site. The other three variants or a variant in complete linkage disequilibrium with them overlap a region of high H3K9ac-promoter-like signature or regions of high enhancer-like signature in the brain or gastrointestinal tissue. Playing an essential role in regulating TACR1 expression, gene polymorphisms of TACR1 serve as the potential pharmacogenetic predictors of response to the NK-1 receptor antagonist-based, triple antiemetic regimens. If clinically approved, modifying the NK-1 receptor antagonist dose leads to better management of CINV in risk-allele carriers.

Efficacy and Safety of Ginger on Chemotherapy-Induced Nausea and Vomiting: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Chemotherapy-induced nausea and vomiting (CINV) is a prevalent and distressing side effect. Historically, ginger has been explored as a potential remedy for various ailments, including its potential efficacy against CINV. The aim of this study was to determine whether taking ginger supplements can relieve CINV. A comprehensive search was conducted across PubMed, EMBASE, Cochrane Library, and the Wanfang database. Randomized controlled trials meeting our inclusion criteria were analyzed. The primary outcomes were the incidence and severity of CINV. The protocol was registered on PROSPERO, and the number is CRD4202232104. Of the 35 randomized controlled trials analyzed, 22 trials employed ginger capsules as the primary intervention, whereas 13 studies evaluated the prophylactic effects of ginger-partitioned moxibustion. The outcomes indicated that combining ginger capsules with standard antiemetic agents can significantly reduce the incidence of grade 3 acute nausea (Risk Ratio [RR], 0.19; P < .001) and the incidence of high-grade overall vomiting (RR, 0.47; P = .01). Moreover, ginger-partitioned moxibustion can significantly alleviate the incidence of both mild (RR, 0.56; P = .001) and severe (RR, 0.39; P < .00001) vomiting. Only 2.8% of patients experienced dizziness after ginger-partitioned moxibustion. Our findings indicate that ginger capsules, when used alongside antiemetic drugs, enhance the management of severe CINV, particularly in highly emetogenic chemotherapy regimens. Based on our findings, we recommend initiating ginger supplements before chemotherapy, in conjunction with standard antiemetics, to reduce the severity of CINV. The promising results warrant more rigorous clinical trials to firmly establish the role of ginger in CINV management.

2020 ASCO, 2023 NCCN, 2023 MASCC/ESMO, and 2019 CCO: a comparison of antiemetic guidelines for the treatment of chemotherapy-induced nausea and vomiting in cancer patients.

Chemotherapy-induced nausea and vomiting (CINV) is a common toxicity that may impair the quality of life of patients with various malignancies ranging from early to end stages. In light of frequent changes to the guidelines for optimal management of CINV, we undertook this narrative review to compare the most recent guidelines published by ASCO (2020), NCCN (2023), MASCC/ESMO (2023), and CCO (2019). The processes undertaken by each organization to evaluate existing literature were also described. Although ASCO, NCCN, MASCC/ESMO, and CCO guidelines for the treatment and prevention of CINV share many fundamental similarities, the literature surrounding low and minimal emetic risk regimens is lacking. Current data regarding adherence to these guidelines is poor and warrants further investigation to improve care.

Prevalence of Chemotherapy-Induced Nausea and Vomiting: An Algerian Study

Prevalence of chemotherapy-induced nausea and vomiting Prospective study at Kasr El Hiran hospital in Laghouat the objective was to study the prevalence of chemotherapy-induced nausea and vomiting (CINV), determine if the prescriptions in our department comply with the recommendations of expert societies, and evaluate the influence of certain patient-specific factors on the occurrence of CINV. This is a prospective observational study conducted at the day hospital of the medical oncology service at EPH Kasr El Hiran Laghouat, spanning a period of 3 months from September 21 to December 21, 2022. At the end of this study, 50 women and 18 men were interviewed, with a mean age of 49.40 years. Breast cancer was the most frequent underlying neoplastic pathology (50%). The majority of chemotherapy protocols used were classified as low emetic risk (44.11%). The prevalence of CINV was 79%, of which 51.9% occurred in the delayed phase. According to our results, none of the risk factors appear to have an influence on the prevalence of CINV, and the prescriptions are not in compliance with the recommendations of expert societies. Our results indicate that the management of CINV remains overall unsatisfactory and could be improved by providing increased accessibility to aprepitant.

Pediatric oncology provider perspectives and patient/family perceptions of chemotherapy-induced nausea and vomiting management: Experiences at an academic medical center.

Chemotherapy-induced nausea and vomiting (CINV) is common in children undergoing cancer treatment, and significantly impacts quality of life. Clinical practice guidelines (CPGs) have been developed to guide CINV management, though many patients do not receive guideline-concordant care. Few studies have examined provider perspectives on CINV management or preferred improvement approaches, or pediatric patient perception of CINV control. A cross-sectional study of pediatric oncology providers was conducted at a large freestanding children's hospital. Providers completed an anonymous online survey about CINV control in patients admitted for scheduled chemotherapy, and their knowledge and utilization of CINV CPGs. A survey of English and Spanish-speaking pediatric oncology patients admitted for scheduled chemotherapy was conducted to assess CINV management, with key demographics used to understand association with perceptions and adherence to antiemetic guidelines. For providers, 75% of respondents felt CINV management could be moderately or extremely improved, significantly more so by chemotherapy prescribers and pediatric medical residents than nurses. Over half of respondents did not have awareness of CINV CPGs, particularly pediatric medical residents. For patients, nausea was reported to be extremely well controlled in 44% of cases, and vomiting extremely well controlled in 50% of cases. There were no significant differences in patient-reported CINV across demographics, when considering emetogenicity of chemotherapy received, or concordance to guidelines. Implementing education in this area may help to improve provider comfort, and ultimately, the patient experience. Future studies will expand upon this novel patient perception, and develop and evaluate CINV management interventions.

Using Follow-Up Telephone Calls to Identify Obstacles to Prevention and Treatment of Chemotherapy-Induced Nausea and Vomiting.

Despite advances in antiemetic regimens, uncontrolled chemotherapy-induced nausea and vomiting (CINV) remains a problem for patients receiving oncology treatment, leading to decreased quality of life and worse treatment outcomes. The purpose of this pilot project was to use follow-up telephone calls to identify barriers related to successful management and prevention of CINV on a single-center outpatient chemotherapy infusion unit. A mixed-methods descriptive design was used for this project. Quantitative data were used to assess barriers to management and prevention of CINV. Secondary multiple regression analysis was used to determine whether barriers could predict CINV. Qualitative data were used to analyze common barriers and themes. Of the patients called (N = 132), 50% identified a barrier to managing and treating CINV, with the most common barrier being knowledge gaps related to proper use of antiemetics.

A Randomized Clinical Trial Investigating an Integrated Nursing Educational Program to Mitigate Chemotherapy-Induced Nausea and Vomiting in Cancer Patients: The NIV-EC Trial

Background: In addition to pharmacological prevention, chemotherapy-induced nausea and vomiting (CINV) can be mitigated through patient education; written supporting materials can be beneficial. Methods: This is a randomized, controlled trial which randomly assigned patients undergoing first chemotherapy cycle to receive oral information regarding CINV prevention and management (control arm) or oral information plus an informative booklet (experimental arm). Overall, 384 cancer patients fulfilling the following inclusion criteria were enrolled: age ≥18 years; life expectancy ≥6 months; no cognitive impairment; written informed consent. After the first cycle, CINV occurrence and its impact on daily activities were assessed using the Functional Living Index Emesis (FLIE). Results: Severe nausea was self-reported by 3.0% and 10.8% of patients in the experimental and control group, respectively (difference: 7.8%; 95% confidence interval: 2.3% to 13.1%). Moderate/high impact of nausea on daily activities was lower in patients also receiving the booklet than in the control group (4.2% and 10.1%, respectively; difference: 5.9%; 95% confidence interval: 0.3% to 11.5%). Vomiting was not statistically different between study arms. Conclusions: This integrated nursing approach was effective in aiding cancer patients in CINV self-management. Although the beneficial effect was moderate, this intervention demands minimal resources in terms of costs and time.

Determining the factors affecting chemotherapy-induced nausea and vomiting in children with cancer

PurposeWe evaluated the factors affecting chemotherapy-induced nausea and vomiting (CINV) in children with cancer. Design and methodsThis cross-sectional study was conducted with 62 children aged 9 to 18 years old with a solid tumor who received chemotherapy for the first time, and their parents. Data were collected using a data collection form, the State-Trait Anxiety Inventory for Children, the Beck Anxiety Inventory, the Spielberger State-Trait Anxiety Inventory, and the Baxter Retching Faces Scale. Data were analyzed using Spearman's correlation and logistic regression analyses. ResultsRisk factors related to the child, treatment, and parent were examined. Child-related factors were determined as diagnosis (odds ratio [OR] = 5.5), time since diagnosis (OR = 1.9, OR = 4.7), pretreatment anxiety of the child (r = 0.439, r = 0.422), and past experience of nausea and vomiting before treatment (OR = 1.2). Treatment-related factors involved anti-emetic prophylaxis (OR = 4.9, OR = 9.2). Parent-related factors included pretreatment anxiety of the parent (r = 0.271, r = 0.287), accommodation (OR = 5.5), not eating (OR = 1.2, OR = 1.3), and bad smell (OR = 1.2), which were described amongst parents' as factors that trigger CINV. ConclusionsThe occurrence of CINV is significantly affected by child-, treatment-, and parent-related risk factors. Practice implicationsPediatric nurses should create an environment for children and their parents to reduce their anxiety and provide basic knowledge and skills about the management of CINV.

Current Management of CINV

Chemotherapy-induced nausea and vomiting (CINV) prevention is important to reduce overall morbidity and financial burden in patients receiving chemotherapy. Severe symptoms reduce the patient's quality of life and can interfere with further treatment. The five major forms of CINV (ie, acute, delayed, predicted, breakthrough, and refractory) often include 5-HT3 receptor antagonists, NK1 receptor antagonists, and various treatments that often include corticosteroids. Despite significant research and development efforts on antiemetics, treatment of CINV remains a major challenge, waiting for many needs to be adequately addressed, including those that are vulnerable to CINV despite adequately treated. This review hope to raise awareness and discuss current current CINV management.

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

Abstract 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.

A Scoping Review on the Relationship between Race/Ethnicity and the Receipt of Supportive Care Medications during Cancer Treatment: Implications for the Clinical Pharmacist.

There is surmounting levels of evidence on the health disparities within cancer treatment in the United States (US). Most of the research focused on cancer specific factors including anticancer incidence, screening, treatment and follow-up, and clinical outcomes such as overall survival (OS). Less is known about the disparities present with supportive care medication use in cancer patients. Supportive care utilization during cancer treatment has been linked to improved quality of life (QoL) and OS among patients. The goal of this scoping review is to summarize findings of current literature on the relationship between race and ethnicity and the receipt of supportive care medications during cancer treatment for pain and chemotherapy-induced nausea and vomiting (CINV). This scoping review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA-ScR) guidelines. Our literature search included quantitative studies, qualitative studies, and grey literature written in the English language with clinically relevant outcomes pertaining to pain and CINV management in cancer treatment published from 2001-2021. Articles that met the predefined inclusion criteria were considered for inclusion in the analysis. The initial search yielded 308 studies. Following de-duplication and screening, 14 studies met the predefined inclusion criteria, with majority of the studies being quantitative studies (n=13). Collectively, results were mixed results regarding the presence of racial disparities for supportive care medication use. Half of the studies (n=7) supported this finding whereas, the other half (n=7) did not identify any racial disparities. In our review, multiple studies illustrate the existence of disparities in the use of supportive care medications in some cancer types. Clinical pharmacists should strive to eliminate supportive medication use disparities as part of a multidisciplinary team. In order to develop strategies to prevent supportive care medication use disparities in this population, further research and analysis of external factors that influence them are needed.

Management of Chemotherapy-Induced Nausea and Vomitting in Breast Cancer Patients: A Prospective Cohort Study

Through a prospective cohort study we aimed to optimize prevention and management of chemotherapy-induced nausea and vomiting (CINV) in the emergence of new therapies for breast cancer patients. We included breast cancer patients treated with moderate emetogenic (MEC) or highly emetogenic chemotherapy (HEC) all stages combined, from April 2021 to November 2021. Patients were required to answer a survey of 32 questions in order to analyze the potential involvement of known and unknown risk factors in the occurrence of CINV. The acute phase of CINV was defined as nausea and vomiting that developed ≤ 24 hours after the start of chemotherapy. Delayed phase of CINV was defined as nausea and vomiting that developed &gt; 24 hours after the start of chemotherapy. The severity of nausea and vomiting was evaluated with common terminology criteria for adverse events (CTCAE) v5.0; publish to date: November 27, 2017. Analysis and results were performed using JAMOVI statistical software. In total, 177 patients received chemotherapy, 103 patients(58%) received (HEC), and 74 patients (42%) received (MEC). All patients were female (100%). Risk factors associated to occurrence of CINV included previously known factors: Younger age than 50 years (29,8%), history of pregnancy-related nausea and vomiting (74,7%), alcohol use (no patient reported previous alcohol consumption), failure to adhere to antiemetic treatment guidelines (9,6%). The compliance with treatment score (90,4%) showed a good commitment of the patients in the process of their medical healthcare. Other potential risk factors have been also explored to determine their involvement or not in the occurrence of CINV (cancer stage, performance status, education level, chemotherapy protocols, the use of traditional herbs known as an antibacterial agent and immunity booster in our context). In the acute phase, (78%) of patients experienced nausea and (47,8%) experienced vomiting. In the delayed phase, (37,1%) of patients experienced nausea and only (15,3%) experienced vomiting. The severity of nausea and vomiting was evaluated according to CTCAE v5.0 in both groups HEC and MEC. Only (8,7%) had to stop treatment for non-tolerance (table 1-2). The present study demonstrated that high compliance to treatment guidelines for CINV and individualized care could lead to more optimal management of CINV.

Evaluation of risk factors for chemotherapy-induced nausea and vomiting in cisplatin and gemcitabine treatment for biliary tract cancer: acid suppressants do not prevent nausea.

Chemotherapy-induced nausea and vomiting (CINV) is one of the most serious adverse effects of cancer therapy. Cancer patients frequently use acid suppressants (AS) for palliation of gastrointestinal symptoms associated with malignancy and/or anticancer therapy. AS are suggested as an additional option for CINV management in several antiemetic guidelines, although their efficacy remains unknown. The aim of this study was to determine whether AS administration affects CINV incidence in cisplatin and gemcitabine treatment for biliary tract cancer. The primary endpoint was to evaluate whether AS administration was associated with the incidence of all-grade nausea in the first administration by logistic analysis. The secondary endpoints were to assess factors associated with anorexia. Prophylactic antiemetics were based on current guidelines. Nausea occurred in 34.2% of patients (grade 1, 31.7%; grade 2, 2.5%). Patients exhibiting vomiting and anorexia represented 4.2% and 39.1%, respectively, without grade 3/4 symptoms. Multivariate analysis suggested that the independent risk factors for nausea as female sex, and no- or less-alcohol drinking habit and regular narcotics administration were associated with anorexia. In contrast, AS administration was not associated with nausea and anorexia incidence (odds ratio, 95% confidence interval: 1.43, 0.64-3.23; P =0.38 for nausea, 1.62, 0.71-3.68; P =0.25 for anorexia). In conclusion, we found that AS administration is not associated with CINV incidence, and female sex is a risk factor for nausea, and non-alcohol drinking habits and regular narcotic use are factors associated with anorexia in cisplatin and gemcitabine treatment for biliary tract cancer. We should correctly administer AS depending on the patient's situation. Successful CINV management needs effective monitoring and administration of prophylactic antiemetics and counter-measure medicines for patients at risk.

The effect of using an interactive mobile application for the management of chemotherapy-induced nausea and vomiting in children: Randomized controlled study.

This study was conducted to develop an interactive mobile application called 5inD, and investigate the effect of 5inD on the management of chemotherapy-induced nausea and vomiting (CINV) in pediatric oncology patients. The prospective, parallel-group and randomized controlled study was conducted in a university hospital between October 2019 and January 2021 with 57 children aged 8-18 years who were treated with chemotherapy and their mothers. In this study, a mobile application called "5inD" was developed, which includes five distraction methods to reduce CINV. Data were collected about CINV through the Adapted Rhodes Index for Nausea & Vomiting child version (ARINVc), and parent version (ARINVp). CINV of the children was evaluated for seven days starting from the first day of chemotherapy. In the study, Child ARINVc and Parent ARINVp mean scores of the intervention groups were lower than the control group during the seven days (p<0.05). There was a statistically significant difference between the group's Adapted Rhodes Index of Nausea and Vomiting for Pediatrics by Child (ARINVc) and by Parent (ARINVp) mean scores in terms of the group, time, and group*time interaction. While a statistically significant difference was found between the intervention group's and control group's mean scores in terms of the group, time, and group*time for the acute CINV (p<0.05), there was no statistically significant difference for delayed CINV between groups scores in terms of the time, and group*time interaction (p>0.05). This study supports the findings that the interactive mobile application was found effective in reducing CINV in children. Additionally, it can be said 5inD is more effective for the management of acute CINV than delayed CINV.

Clinical Updates in Nausea and Vomiting.

To review recent updated antiemetic guidelines from national cancer organizations and its impact on chemotherapy-induced nausea and vomiting (CINV) in the prevention and delayed phase of therapy. This article will also describe assessment and nursing strategies for individualized care and timely side effect management. Data sources include peer-reviewed articles sourced in electronic databases. CINV is a persistent problem for a large percentage of patients undergoing chemotherapy treatment despite advances in antiemetic therapy and increased use of targeted therapies. CINV management should be based on patient-focused assessment and adherence to national antiemetic guidelines. Ongoing assessment and follow-up are critical to ensure optimum management of side effects to optimized quality of life. Awareness of national antiemetic guidelines is important in caring for patients undergoing chemotherapy. CINV can have a significant impact on patients, causing physical effects, treatment delays, and diminished quality of life. Oncology nurses play a key role in assessment of patient-related risk factors, education of patients and caregivers regarding pain medications, side effects, and oral adherence and continued follow-up for early recognition and intervention for uncontrolled CINV.

The Role of Clinical Guidelines for the Management of Chemotherapy-Induced Nausea and Vomiting in Children with Cancer

Background: Nausea and vomiting are among the most important side-effects associated with chemotherapy in children with cancer, affecting the quality of their lives. Clinical guidelines for selecting antiemetics are effective in reducing acute chemotherapy-induced nausea and vomiting (CINV). Materials and Methods: The present quasi-experimental study compared the effectiveness of the Pediatric Oncology Group of Ontario (POGO) CINV guideline with that of conventional arbitrary therapies for CINV in 82 children aged 6 months to 16 years old. Out of 177 cycles of chemotherapy, in 101 cycles patients were treated according to POGO-CINV Guideline; in the other 76 cycles, patients were treated with arbitrary types and doses of antiemetics. Then, vomiting in the first 24 hours after chemotherapy in both groups was measured and compared. Results: In this study, 82 patients hospitalized in the Hematology Department of Dr. Sheikh Children’s Hospital were enrolled, of whom 48 patients (58.7%) were boys and 34 (41.3%) were girls. The mean age of patients was 6.24±4.47 years (6 months to 16 years). The results of the current study showed that using a protocol for the prevention of vomiting based on the patient’s age and the type of chemotherapy is superior to conventional management of CINV. Findings showed that the frequency of nausea and vomiting in the protocol group was significantly reduced in comparison with the control group (p˂0.005). Moreover, a reduction in the frequency of nausea and vomiting was quite significant in the sub-categories of the protocol group who had received high-risk or moderate-risk emetogenic drugs (p˂0.005). Conclusion: The results of the current study showed that using the POGO guideline, which takes into account the patient’s age and the type of chemotherapy, is more effective than arbitrary management of CINV, particularly in children.
