Impact of adjuvant lorazepam with granisetron on chemotherapy-induced nausea and vomiting in pediatric patients with acute lymphoblastic leukemia

Anti-Emetics in Children Receiving Chemotherapy for Solid Tumors and Leukemia: Pharmacology and Optimization of Therapy for Nausea and Vomiting

The management of chemotherapy-induced nausea and vomiting (CINV) in children remains challenging due to differences in the chemotherapy regimens, their relative emetogenicity compared to that in adults and differences in drug metabolism and the available formulations. The common four classes of anti-emetics used for the treatment and prophylaxis of CINV in children include dexamethasone, neurokinin-1 receptor antagonists, 5-hydroxytryptamine-3 receptor antagonists (5HT3RAs), and olanzapine. The appropriate dose of dexamethasone for CINV prophylaxis in children is unknown, with a significant variability in dosage ranging between 6 and 32 mg/m2/day. The dose of dexamethasone is decreased by 30% when this drug is combined with (fos)aprepitant in children, in contrast to a decrease of 50% required in adults. The use of aprepitant in younger children (<12 years) is often hampered by the non-availability of oral suspension formulations in many countries; alternatively, 80 mg capsules are administered for 1-3 days in certain institutes to children weighing between 15 and 40 kg. Among the different 5HT3RAs, palonosetron is comparatively metabolized faster in children than in adults, requiring a higher dosage for similar efficacy to that achieved in adults. Olanzapine is a newer agent, used in doses between 0.1 and 0.14 mg/kg/day in children, with good anti-emetic efficacy, but has sedation and hyperglycemia as concerning adverse effects. Drug interactions between anti-emetics and between anti-emetics and chemotherapy/supportive agents (azole antifungals, cyclosporine, arsenic trioxide), especially QTc prolongation, should be considered during prescription.

Risk factors associated with nausea and vomiting in children with cancer receiving chemotherapy

INTRODUCTION

Despite treatment with antiemetic medications, nausea remains uncontrolled for many children receiving chemotherapy. One reason is that risk factors for nausea in children remain poorly explored. The purpose of this study was to identify risk factors for chemotherapy-induced nausea (CIN) in children.

METHODS

Prospective, observational study including 101 children (median age 6.4 years, range 0.8-17.9) with cancer receiving moderately or highly emetogenic chemotherapy. Primary endpoints were complete control of acute and delayed CIN, defined as no nausea in the acute phase 0-24 h after chemotherapy and in the delayed phase starting after the acute phase and ending 5 days later. Multivariable analyses included age, sex, cancer type, susceptibility to motion sickness, chemotherapy duration, numbers of antiemetics, co-administration with opioids or tricyclic antidepressants, and previously uncontrolled nausea or vomiting.

RESULTS

Acute CIN was associated with susceptibility to motion sickness (odds ratio [OR] 5.73, 95% confidence interval [CI] 1.36-33.7) and older age (OR 4.19, 95% CI 1.30-14.7), comparing age group 8-18 years with 0-3 years. Delayed CIN was associated with uncontrolled acute nausea or vomiting (OR 10.3, 95% CI 2.65-50.9), highly emetogenic chemotherapy (OR 8.26, 95% CI 1.17-76.8), and having a hematologic cancer type (OR 7.81, 95% CI 1.05-79.2).

CONCLUSIONS

Susceptibility to motion sickness and age can influence the risk of acute CIN. More research is needed on how best to integrate risk information in preventive antiemetic strategies. Sufficient acute nausea and vomiting control are crucial to prevent delayed CIN.

Risk factors for chemotherapy-induced vomiting after general anesthesia in children with retinoblastoma: a retrospective study

BACKGROUND

The chemotherapy-induced vomiting (CIV) severely affects the daily function, nutritional status, treatment compliance, therapeutic efficacy, curability, and the quality of life of patients. The aim of this study was to find the risk factors for CIV after general anesthesia in patients with retinoblastoma (RB).

METHODS

A retrospective review of the hospital records of children with RB, who underwent chemotherapy between January 2017 and December 2019, was conducted at our hospital.

RESULTS

Data of a total of 803 children with RB were reviewed. The incidence of CIV in children with RB was 19.30%. Univariate analysis showed statistically significant differences in age, height, weight, chemotherapy regimen, anesthesia dose, duration of surgery and general anesthesia, platelet count, platelet distribution width, lymphocytes, and indirect bilirubin between patients with and without vomiting (P<0.05). Multivariate logistic regression analysis showed that the main predictors of CIV in children with RB included older age [odds ratio (OR), 1.32; 95% confidence interval (CI): 1.11-1.56; P<0.01], low platelet count (OR, 0.997; 95% CI: 0.995-0.999; P<0.05), and chemotherapy regimen (intravenous chemotherapy versus intra-arterial chemotherapy; OR, 0.47; 95% CI: 0.29-0.76; P<0.01).

CONCLUSIONS

This study revealed age, chemotherapy regimen, and platelet count as risk factors of CIV after general anesthesia in children with RB. Younger age and higher platelet count were protective factors for CIV. Compared with intravenous chemotherapy, the incidence of CIV was lower than that of intra-arterial chemotherapy. Although these factors cannot be modified, they can predict whether a patient may experience vomiting, assisting medical staff to formulate measures and intervenes in advance.

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

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

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.

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

PURPOSE OF REVIEW

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

RECENT FINDINGS

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