Objective: To observe efficacy and side effects, as well as the impact on quality of life, of Kanglaite$^{(R)}$ (Coix Seed Oil) injections combined with chemotherapy in the treatment of advanced gastric cancer patients. Method: A consecutive cohort of 60 patients were divided into two groups: the experimental group receiving Kanglaite$^{(R)}$ Injection combined with chemotherapy and the control group with chemotherapy alone. After more than two courses of treatment, efficacy, quality of life and side effects were evaluated. Results: The response rate and KPS score of experimental group were significantly improved as compared with those of the control group (P<0.05). In addition, gastrointestinal reactions and bone marrow suppression were significantly lower than in the control group (P<0.05). Conclusions: Kanglaite$^{(R)}$ Injection enhanced efficacy and reduced the side effects of chemotherapy, improving quality of life of gastric cancer patients; use of Kanglaite$^{(R)}$ injections deserves to be further investigated in randomized control clinical trails.
