Anxiety and drug taste as predictors of anticipatory nausea in cancer chemotherapy.
Interview data from 192 patients receiving cytotoxic chemotherapy for the first time were analyzed to identify factors predictive of the development of anticipatory nausea. Posttreatment nausea and vomiting (particularly vomiting), tastes of drugs during injections, and anxiety before injections were all associated with an increased probability of anticipatory nausea. An index consisting of those three variables, plus age, was found to have good predictive power, even when the predictor variables were assessed only at the first chemotherapy administration and the index was used to predict the development of anticipatory nausea at any time during the first six chemotherapy cycles.
