Neoadjuvant therapy of regional intra-arterial chemoembolization combined systemic vein chemotherapy for locally advanced gastric cancer / 中华普通外科杂志

ABSTRACT

Objective To investigate the efficacy and safety of preoperative regional intra-arterial chemoembolization combined with systemic vein chemotherapy in the treatment of locally advanced gastric cancer.Methods The clinical data of 78 locally advanced gastric cancer patients treated by radical D2 gastretomy from January 2010 to December 2012 were retrospectively analyzed.Patients were devided into treatment group receiving regional intra-arterial chemoembolization combined with systemic vein chemotherapy (n =36),and those with preoperative systemic vein chemotherapy (n =42) 3 to 4 weeks before surgery.Systemic chemotherapy with mFOLFOX6 was started after 5 weeks of surgery in the two groups.Results The incidence of toxicity reaction and postoperative anastomotic leakage were lower in treatment group than in control group,all P ＜ 0.05.The 1-year recurrence and overall survival rate were similar between the two groups (all P ＞ 0.05).The 3-year liver metastasis rate was higher in treatment group than in control group (x2 =4.063,P ＜ 0.05).The 3-year survival rate was higher than that of the control group(x2 =4.396,P ＜ 0.05).Conclusions Preoperative systemic vein chemotherapy combined with regional intra-arterial chemoembolization decreases toxicity reaction,anastomotic leakage and liver metastasis,while prolonging 3-year overall survival.
