Psychological predictors of chemotherapy-induced nausea in women with breast cancer: Expectancies and perceived susceptibility.

ABSTRACT:

Objective

Chemotherapy-induced nausea is challenging to predict and treat. Research indicates that pretreatment psychological variables including patients' perceptions of their susceptibility to nausea, expectancies of treatment-related nausea and nausea history (i.e., motion sickness, morning sickness and baseline levels of nausea) may aid in predicting nausea severity during chemotherapy. However, this research is dated and limited in quantity. We investigated whether psychological variables could improve prediction of nausea severity to inform interventions targeting chemotherapy-induced nausea.

Methods

In this secondary analysis, a subgroup of women receiving chemotherapy (for the first time) for breast cancer completed pretreatment measures: perceived nausea susceptibility, nausea expectancies, nausea history and baseline nausea. They rated subsequent nausea severity across 4-days, during treatment and posttreatment in a self-report diary. Structural Equation Modelling was used to explore associations.

Results

Across the women (N = 481), perceived nausea susceptibility predicted subsequent nausea severity (β = 0.16), but nausea expectancies did not (β = 0.05). Nausea history variables demonstrated small-moderate associations with perceived susceptibility (β = 0.21-0.32) and negligible-small associations with nausea expectancies (β = 0.07-0.14).

Conclusion

Perceived nausea susceptibility appears to capture patients' nausea history, to a degree, and is related to nausea severity during treatment. This is an important variable to include in pretreatment prediction of patients at risk of severe nausea.

Project description:ImportanceThe prevention of chemotherapy-induced nausea and vomiting has an important role in the overall management of cancer treatment.ObjectiveTo evaluate whether adding aprepitant to palonosetron and dexamethasone can further prevent the incidence and severity of nausea and vomiting caused by FOLFIRI (fluorouracil, leucovorin, and irinotecan) or FOLFOX (fluorouracil, leucovorin, and oxaliplatin) chemotherapy regimens among women with gastrointestinal cancer at higher risk.Design, setting, and participantsThis phase 3, double-blind, placebo-controlled randomized clinical trial recruited young women (age ≤50 years) who drank little or no alcohol and had gastrointestinal cancer for which they received FOLFOX or FOLFIRI chemotherapy. A total of 248 women were enrolled and assigned in the ratio 1:1 to intervention and control groups from August 4, 2015, to March 31, 2020. Intention-to-treat analysis was used to evaluate patient baseline characteristics and efficacy. The analysis was conducted on October 30, 2020.InterventionsPatients were randomly assigned to the aprepitant group (aprepitant, 125 mg, orally 60 minutes before initiation of chemotherapy on day 1 and 80 mg orally each morning of days 2 and 3; palonosetron, 0.25 mg, intravenously; and dexamethasone, 6 mg, orally 30 minutes before chemotherapy initiation on day 1) or the placebo group (placebo, 125 mg, orally 60 minutes before initiation of chemotherapy on day 1 and 80 mg orally on each morning of days 2 and 3; palonosetron, 0.25 mg, intravenously; and dexamethasone, 12 mg, orally 30 minutes before chemotherapy initiation on day 1).Main outcomes and measuresThe primary end point was the complete response (CR) rate, defined as the proportion of patients without emesis episodes or rescue medication use during the overall phase of the first cycle. Other efficacy indicators, such as no vomiting and no nausea, were measured as the secondary and exploratory end points.ResultsA total of 248 women from 4 clinical centers in China entered this study, and 243 patients (aprepitant regimen, 125 patients [51.4%]; placebo regimen, 118 patients [48.5%]) were evaluable for efficacy and safety; mean (SD) age of the total population was 40.1 (7.3) years. The CR rate was significantly higher in the aprepitant group vs the control group overall (107 [87.0%] vs 80 [66.7%]; P < .001) and in the acute (114 [92.7%] vs 91 [75.8%]; P = .001) and delayed (109 [88.6%] vs 84 [70.0%]; P = .001) phases of the trial. The incidence of adverse events was similar between the 2 groups (100 [80.0%] vs 96 [81.3%]; P = .79), and no grade 3 or 4 aprepitant treatment-related adverse events were observed. Multivariable analysis revealed that aprepitant use was the only independent factor associated with CR during the overall phase.Conclusions and relevanceThe combination of aprepitant with palonosetron and dexamethasone provided increased antiemetic efficacy in the FOLFOX or FOLFIRI chemotherapy regimen and was well tolerated by younger women with gastrointestinal cancer who have a history of little or no alcohol consumption.Trial registrationClinicalTrials.gov Identifier: NCT03674294.
