Abstract

In gastric cancer, the only potentially curative treatment is surgery that attempts to achieve curative (R0) resection. However, despite the use of curative resection, a recurrence develops in a high percentage of patients, especially in cases of serosa and/or lymph node involvement. As a strategy to improve the survival of the patients with resectable advanced gastric cancer, neoadjuvant chemotherapy has been evaluated in several phase II trials and a few phase III trials. The results of these trials have confirmed the feasibility and safety of this approach with no apparent increase in surgical complications. Recently, the findings of a large phase III randomized trial (MAGIC trial) have indicated that compared to the use of surgery alone, perioperative chemotherapy, using both a neoadjuvant and adjuvant strategy, decreased the number of T and N stage cancers and improved survival. The results of another recent phase III trial (FNLCC 94012/FFCD 9703) also showed that compared to the use of surgery alone, perioperative chemotherapy improved the R0 resection rate and survival. In both trials, the improved outcomes may be attributed to the use of neoadjuvant chemotherapy because of poor compliance with adjuvant chemotherapy. These results cannot be directly translated to clinical practice in Korea due to differences in surgical techniques and outcomes. However, the findings of a few small phase II and III trials performed in patients with locally advanced gastric cancer in Korea have also suggested that neoadjuvant chemotherapy would result in the improvement of the R0 resection rate and down-staging of the disease. More effective chemotherapy regimens are needed in future large randomized trials to determine the subset of patients that will benefit from neoadjuvant chemotherapy and to determine the extent of benefit.
