Pre-operative chemotherapy for gastric cancer.

Gastric cancer is highly prevalent in several countries around the world and remains an incurable disease. Treatment involves surgery, chemotherapy and radiation. Surgical resection remains the definitive treatment for early stage (T1 and T2) gastric cancer, with 5-year survival rates of 70 - 95%. Localized tumours that extend beyond the submucosa are, however, associated with worse outcomes and a 5-year survival rate of 20 - 30%. Recent advances mainly concern chemotherapy prior to surgical resection. The goal of pre-operative chemotherapy is to allow an early attack on systemic micrometastatic disease and, by downstaging the primary tumour, to increase the percentage of patients able to undergo curative resection. Pre-operative chemotherapy remains experimental, but several phase II and III studies have shown promising results. One approach involves systemic, pre-operative chemotherapy for resectable gastric cancer. This review focuses on the development of pre-operative chemotherapy as a component of the multimodal treatment of gastric cancer.
