[Progression of preoperative regional arterial infusion chemotherapy in advanced gastric cancer].

The outcome of surgery alone for advanced gastric cancer is unsatisfactory. Local recurrence rate and distant metastasis rate are still high in postoperative patients. In recent years, people have paid more attention to neo- adjuvant chemotherapy, because it can reduce tumor loading, degrade the staging, increase the surgery excision rate and improve the long-term survival. Preoperative regional arterial infusion chemotherapy can directly act on the tumor endothelial cells with higher local drug concentration, but with fewer systemic side effects. So it may offer an effective treatment for advanced gastric cancer. The indications, complications, therapeutic evaluation, timing of surgery, chemotherapy regimens and pathomorphological changes and so on of the preoperative regional arterial infusion chemotherapy are summarized in this review.
