Background
We previously reported in the SENRI trial on the usefulness of aprepitant for the prevention of chemotherapy-induced nausea and vomiting (CINV) in colorectal cancer patients receiving an oxaliplatin-based regimen which is classified as moderately emetogenic cancer chemotherapy. In the present subgroup analysis of the SENRI trial, we assessed the risk factors for CINV in colorectal cancer patients who received oxaliplatin-based chemotherapy.
Methods
Multivariate logistic regression models were used to assess the impact of aprepitant use and patient characteristics on vomiting and nausea. We also assessed the proportion of CINV in patients by gender.
Results
Female gender and aprepitant use were associated with the incidence of vomiting and no significant nausea. Significantly more men achieved no vomiting than women (92.9 vs 84.5 % in men and women, respectively; P = 0.0001). The rate of no nausea, complete response, complete protection, and total control was also higher in men. The rate rescue therapy use was significantly higher in women than men. We compared the rate of CINV between aprepitant and control groups and found a significant difference in male patients who achieved no vomiting and complete protection in the overall phase. In women, the rate of no nausea, no vomiting, and total control was higher in the aprepitant group than in the control group.
Conclusions
Gender and aprepitant use were risk factors for CINV in colorectal patients who received oxaliplatin-based chemotherapy. Aprepitant therapy was more effective for women than for men in the prevention of CINV in colorectal cancer patients receiving an oxaliplatin-based regimen.
