Nausea and vomiting (N&V) remain among the most feared side effects of chemotherapy (CT). In addition to type of CT, several patient risk factors for CINV have been consistently reported in the literature. A large dataset was assembled to develop a repeated measures cycle based model that would accurately predict the risk of ≥ grade 2 CINV (≥3 vomiting episodes) over 5 days post CT.
CINV outcomes and risk factor data were obtained from 1198 patients enrolled in 1 of 5 non-interventional prospective cohort studies. For the cycle-based risk model, disease and treatment factors that were potential predictors of CINV were identified at baseline and after each cycle of CT. Factors with a p-value
Over 4197 cycles of CT, 42.2% of patients experienced ≥ grade 2 CINV. Ten risk factors were retained in the final model (eg, age
Risk of CINV varies according to number of cycles administered, type of CT, N&V in the prior cycle, and patient factors. The application and continued refinement of this prediction tool will be an important source of patient-specific risk information that will allow the personalization of antiemetic therapy.
