Abstract:
Objective To evaluate and analyze the CT imaging of preoperative SOX regimen neoadjuvant chemotherapy in the treatment of advanced gastric cancer.Methods A total of 33 patients with advanced gastric cancer treated in our hospital from January 2010 to February 2015 were enrolled for the study and given tegafur gimeracil oteracil potassium capsule plus oxaliplatin for injection as preoperative adjuvant chemotherapy.And all the patients were given surgery after 3 cycles of SOX regimen chemotherapy, and surgical resection of the tumor was taken as the final pathology gold standard.The CT imaging data of the patients before and after the chemotherapy was counted and then analyzed and compared with the pathological data to clarify the value of CT imaging in the evaluation of SOX regimen neoadjuvant chemotherapy for advanced gastric cancer.Results The effective rate was 33.33% and the ineffective rate was 66.67% in the preoperative SOX regimen neoadjuvant chemotherapy for advanced gastric cancer through clear surgical pathology.The correlation between tumor volume reduction and pathological grading was the strongest(r=0.581, P<0.001).By ROC analysis, the best area value(AUC) of the tumor volume reduction rate was 0.834.When the tumor volume reduction rate with 36.94% was taken as the effective threshold for SOX regimen neoadjuvant chemotherapy, the sensitivity and specificity of the evaluation were the best with 74.62% and 83.01% respectively.Conclusion sCT volume measurement can be used as a reliable clinical data to evaluate the efficacy of preoperative SOX regimen neoadjuvant chemotherapy in the treatment of advanced gastric cancer and have certain guiding significance in the late treatment of patients with advanced gastric cancer.
