A randomised phase II/III trial evaluating preoperative chemoradiotherapy versus preoperative chemotherapy in patients undergoing adequate surgery for resectable gastric cancer.

See ANZCTR for full trial details >

 

Trial Summary:

Although in developed countries the incidence of gastric cancer has dramatically decreased, gastric cancer is still a leading cause of cancer-related deaths worldwide. Surgery is the only potentially curative treatment. Although the survival rates for patients with early stage disease (stage 1A and 1B) are good, this subgroup of patients constitutes only 20% of those undergoing resection. Most patients have locally advanced or metastatic disease at presentation. The current 5-year survival rate for gastric cancer in Western countries is 20-30%, which has improved little over the past 30 years.

The primary objective of TOPGEAR is to investigate whether addition of chemoradiotherapy to neoadjuvant chemotherapy is superior to chemotherapy alone in improving the pathological complete response rates, and subsequently for overall survival.
