    Abstract:
    Some factors have demonstrated an influence on emesis and antiemetic response. In order to study these factors, 306 patients (pts) entered this study receiving cisplatin based combination chemotherapy (CT) (100 mg/m3, with ondansetron (8 mg, 3 times daily for 4 days) as the only antiemetic treatment. Known factors that influence the result of antiemetic therapy such as age, sex, performance status (Karnofsky), site of primary tumor, weight loss, anxiety, depression, psychological problems related to CT (psychological PRC) etc, were included in the evaluation. We evaluated the number of vomits, retches and nausea. The existence of psychological PRC was found to be a prominent factor for the development of nausea and emesis, being at the same time strongly associated with scaling variables (Gralla, retching and nausea grading) used to measure the severity of nausea and emesis (p = 0.001). Stress was also a significant predictor; patients with stress had an almost two times higher probability to develop nausea or retching compared to patients without stress indications (p = 0.001), while the occurrence of retching was marginal. Younger patients (less than 40 years old) were found to be almost three times more susceptible to retching compared to older patients (more than 40 years old) (P 0.006). With all possible evaluations, we concluded that significant factors are psychological PRC, stress and age. In conclusion, three factors, age, stress and psychological PRC, should be taken seriously into consideration in the design of future trials evaluating antiemetic treatment, as well as in the every-day clinical practice, in order to provide patients with a better quality of life during emetogenic CT.
