BACKGROUND: The aim of this study was to explore the clinical efficacy and safety of conversion surgery in the treatment of stage IV gastric cancer, and to analyze the influencing factors for the prognosis of patients.
METHODS: The clinical data of 84 patients with stage IV gastric cancer treated in our hospital from September 2014 to March 2016 were collected. All patients were treated with S-1 + oxaliplatin or S-1 + docetaxel chemotherapy, among which 42 patients had surgical indications after chemotherapy and received gastrectomy (R
RESULTS: In the conversion surgery group, the median chemotherapy cycle was 4.3, and the objective response rate (ORR) was 73.8% (31/42). During chemotherapy in the two groups, there were 22 cases (52.3%) and 24 cases (57.1%) of hematological toxicity, and 28 cases (66.7%) and 32 cases (76.2%) of non-hematological toxicity, mainly in grade I-II, which could be relieved after symptomatic treatment, and chemotherapy was successfully completed. After chemotherapy, 42 out of 84 patients met the surgical indications. All patients were followed-up for 6-36 months. The 3-year overall survival was 35.7% (15/42) and 9.5% (4/42), respectively, in the two groups, and the difference was statistically significant according to the log-rank test (P<0.05). The results of multivariate analysis showed that whether the surgical margin was R
CONCLUSIONS: Radical surgery after conversion therapy can raise the survival rate of patients, with tolerable adverse reactions. Whether the surgical margin is R
