Abstract
OBJECTIVE:To observe the efficacy and safety of sequential chemotherapy on the basis of 5-FU combined with three-dimensional conformal intensity modulated radiotherapy in the treatment of postoperative advanced gastric cancer. METH-ODS:110 patients with advanced gastric cancer were randomly divided into control group(55 cases)and sequential group(55 cas-es). Control group was given 400 mg/(m2·d) 5-FU injection by intravenous injection,then given 600 mg/m2 for continuous infu-sion 22 h,d1-2+50 mg/d Pirarubicin hydrochloride for injection,intravenous injection,d1+150 mg/d Oxaliplatin for injection,intra-venous injection,d1,three-dimensional conformal intensity modulated radiotherapy was conducted for 2 weeks after the 4th chemo-therapy,and the total dosage was DT40-45 Gy/1.8 Gy/24-25F. sequential group was additionally given three-dimensional conformal intensity modulated radiotherapy;3-week was regarded as a treatment course,and it lasted 6 courses. The total survival rate and progression-free survival rate in 1,2 and 3 years,metastasis rate and incidence of adverse reactions in 2 groups were followed-up. RESULTS:The total survival rate and progression-free survival rate in 1,2 and 3 years in sequential group were significantly high-er than control group,lymphatic metastasis rate and distant metastasis rate in sequential group were significantly lower than control group,the differences were statistically significant (P<0.05). And there were no significant differences in the nausea,vomiting, hair loss and incidence of bone marrow suppression between 2 groups (P>0.05). CONCLUSIONS:Sequential chemotherapy on the basis of 5-FU combined with three-dimensional conformal intensity modulated radiotherapy can effectively prolong the survival time and reduce long-term metastasis rate of patients in the treatment of postoperative advanced gastric cancer,with similar safety.关键词
