Acute chemotherapy-induced nausea and vomiting in children with cancer: Still waiting for a common consensus on treatment

Chemotherapy-induced nausea and vomiting (CINV) is one of the most common treatment side-effects, and remains a significant concern, in children undergoing chemotherapy. Although adult patients receive chemotherapy regimens combined with appropriate standardized antiemetic treatment, children can receive markedly varying antiemetic treatments. A narrative review of CINV was performed regarding CINV definition, scoring system, prevention and treatment, specifically focussing on studies conducted with paediatric oncology patients. The review highlighted a lack of rigorously developed CINV scoring systems and standardized CINV pharmacological treatment for paediatric oncology patients. Different scoring systems were found to identify potential risk factors for CINV associated with the use of several different antiemetic drugs, however, few studies have been performed in children undergoing chemotherapy. Thus, CINV remains a distressing and partially controlled side-effect in the paediatric patient population. To reduce emesis and improve quality of life in paediatric oncology patients, standardized antiemetic treatment may be preferred, using a unique CINV scoring system that accounts for the emetogenic level of the chemotherapy regimen adopted and the children’s clinical characteristics.

Comprehensive study of risk factors for chemotherapy-induced nausea and vomiting in cancer patients receiving cisplatin-based chemotherapy: A TRIPLE pharmacogenomics study.

10091 Background: Chemotherapy-induced nausea and vomiting (CINV) is one of the most unpleasant adverse effects of chemotherapy. Resistance to prophylactic antiemetic treatment is problematic, with 30%–50% of patients experiencing unsatisfactory control. Younger age and female sex are well-known risk factors for CINV. Genetic polymorphisms are suggested to influence antiemetic treatment response. Methods: This study included a subset of patients previously enrolled in a randomised controlled trial. This study aimed to evaluate the role of pharmacogenomic polymorphisms relevant to antiemetic response in patients with cancer receiving cisplatin-based chemotherapy. The study’s efficacy endpoint was the proportion of patients with complete response (CR). The study endpoint was evaluated separately in the acute (CR0-24) and delayed (CR24-120) phases. Thirteen polymorphisms were genotyped, and the association of these genotypes with the efficacy of prophylactic antiemetics was then investigated. Confounding variables for CR were identified using stepwise multivariate logistic regression analysis. Age and sex were included as independent variables by the forced-entry method, and the stepwise method was used to select the pharmacogenomic factors for inclusion as independent variables. Results: In this genetic polymorphism association study, 156 patients with solid cancer were evaluated. Multivariate logistic regression analysis revealed that ERCC1 8092AA (odd ratio [OR]: 11.251; 95% confidence interval [CI]: 1.741–72.712, P = 0.011) and female sex (OR = 3.630; 95% CI = 1.138–11.578, P = 0.029) were significant predictors of CR0-24. No significant association of CR24-120 with pharmacogenomic polymorphisms was found via multivariate logistic regression analysis. Conclusions: ERCC1 polymorphism might be influenced the extent of CINV control in patients receiving cisplatin-based chemotherapy. Clinical trial information: 000009335.

Efficacy of triple antiemetic therapy (palonosetron, dexamethasone, aprepitant) for chemotherapy-induced nausea and vomiting in patients receiving carboplatin-based, moderately emetogenic chemotherapy.

226 Background: Chemotherapy-induced nausea and vomiting (CINV) is a major adverse toxicity of cancer chemotherapy. Recommended treatments for prevention of CINV vary among guidelines, and optimal care for CINV caused by moderately emetogenic chemotherapy has not been established. This study assess efficacy and safety of triple antiemetic therapy consist palonosetron, dexamethasone and aprepitant for carboplatin-based chemotherapy. Methods: Chemotherapy-naïve patients with lung cancer scheduled for a first course of a carboplatin-containing regimen formed the study cohort. Patients were pretreated with antiemetic therapy consist palonosetron (0.75 mg, i.v.) and dexamethasone (9.9 mg, i.v.) on day 1, and aprepitant (125 mg, p.o.) on day 1 followed by 80 mg on days 2 and 3. Primary endpoint was the proportion of patients who did not experience vomiting and did not require rescue medication (complete response (CR)) in the acute phase (0-24 h), late phase (24-168 h) and overall. Secondary endpoint was the proportion of patients who experienced no vomiting episodes and no more than mild nausea without the need for rescue medication (complete control (CC)). Results: Prevalence of a CR during the acute phase, delayed phase, and overall was 100%, 91.9% and 91.9%, whereas that of CC was 100%, 84.4% and 84.4%, respectively. Most common adverse events were mild constipation; severe adverse events related to antiemetic treatment were not observed. Prevalence of a CR during the acute phase, delayed phase, and overall was 100%, 91.9% and 91.9%, whereas that of CC was 100%, 84.4% and 84.4%, respectively. Most common adverse events were mild constipation; severe adverse events related to antiemetic treatment were not observed. Conclusions: Triple antiemetic therapy comprising palonosetron, dexamethasone and aprepitant shows excellent effects in preventing CINV in patients receiving a carboplatin-containing regimen.
