Abstract: ObjectiveTo evaluate the clinical effect of compound glutamine in the adjuvant treatment after radical surgery of gastric cancer. MethodsA total of 63 cases with gastric cancer after radical resection were randomly divided into treatment group and control group, according to random number table. 32 patients in treatment group received simultaneous threedimensional conformal radiotherapy with capecitabine monotherapy regimen, while oral administration of compound glutamine entericcoated capsules. 31 cases in control group only received chemoradiotherapy. ResultsIn treatment group, the quality of life score for the excellent and good accounted for 40.6% and 34.4%, significantly higher than 16.1% and 12.9% in control group respectively (χ2＝4.63, P＝0.03; χ2＝4.00, P＝0.04). The incidence of nausea and vomiting, abdominal pain and diarrhea in treatment group respectively were 31.3% and 37.5%, significantly less than 61.3% and 64.5% in control group with statistical significance （χ2＝5.72, P＝0.02; χ2＝4.60, P＝0.03）. The incidence of gastrointestinal reactions in treatment group were mainlyⅠand Ⅱdegrees, and ⅢⅣ degree of gastrointestinal reactions were not appear. While the antidiarrheal drugs (21.9% vs. 48.4%) and analgesics drugs (15.6% vs. 38.7%) in the treatment group were significantly reduced compared with the control group （χ2＝4.87, P＝0.03; χ2＝4.26, P＝0.04）. ConclusionBy administration of compound glutamine in the course of adjuvant chemotherapy after radical surgery of gastric cancer can improve the quality of life, reduce chemotherapyinduced gastrointestinal side effects, improve treatment compliance, and successfully complete the treatment.
