Phase II Trial of Preoperative Chemoradiation in Patients With Localized Gastric Adenocarcinoma (RTOG 9904): Quality of Combined Modality Therapy and Pathologic Response

Abstract

For localized gastric cancer, preoperative chemoradiotherapy strategy achieved a pathCR rate of more than 20% in a cooperative group setting. The quality of surgery improved (50% with D2 dissection) possibly because surgery was part of this trial. With some refinements, this preoperative chemoradiotherapy strategy is poised for a randomized comparison with postoperative adjuvant chemoradiotherapy in patients with gastric cancer.
