Abstract:Objective To study clinical effect of elemene oral emulsion combined with docetaxel and oxaliplatin in treatment of patients with advanced esophageal squamous cancer. Methods Totally 44 cases with advanced esophageal squamous cancer were selected as the objects of the study and divided into observation group (n?=?21, elemene oral emulsion combined with docetaxel and oxaliplatin) and control group (n?=?23, docetaxel and oxaliplatin), and 21 days was a chemotherapy cycle. Effect, living quality, weight, toxocity and immunity of advanced esophageal squamous cancer were made comments after 2 cycles. Results There was no significant difference in total effective rate and disease control rate between two groups (P?>?0.05). The difference of Karnofsky performance score before and after chemotherapy in the observation group was statistically significant (P?0.05), but the control group was the opposite (P?>?0.05). The living quality of the observation group was higher than that of the control group, and the difference was statistically significant (P?0.05). The weight difference between the observation and the control group before and after chemotherapy was not statistically significant (P?>?0.05). Patients gaining weight of the observation group was more than that of the control group,and the difference was statistically significant (P?0.05). The observation group was superior to the control group in WBC reduction, PLT reduction, ALT elevation and gastrointestinal reaction after chemotherapy, and the difference of two groups was statistically significant (P?0.05). The changes of NK cell activity in the observation group and the control group after chemotherapy were statistically significant (P?0.05); the difference of ratio of CD4+ and CD8+ was statistically significant (P?0.05). Conclusions Elemene oral emulsion combined with docetaxel and oxaliplatin can improve the living quality and increase the weight of patients with advanced esophageal squamous cancer, with good safety and no serious adverse side effect.
