Current status of adjuvant chemotherapy for gastric cancer

Although radical gastrectomy is a standard treatment for advanced gastric cancer, recurrence remains high. After several large-scale controlled studies have shown the beneficial effects of adjuvant chemotherapy, that treatment emerged as a standard option for advanced gastric cancer after gastrectomy. However, various guidelines from different countries have suggested different adjuvant chemotherapies. Understanding the differences between guidelines is very important for investigating further therapeutic strategies. Fortunately, because there are many ongoing studies about new regimens for adjuvant treatment, it is expected that patients with gastric cancer after surgery will have better outcome.
