A prospective, randomized trial of pre-operative and intraoperative radiotherapy versus surgery alone in resectable gastric cancer.

Introduction: Worldwide, gastric cancer remains one of the most common malignancies. Discouraging survival rates after surgical treatment promote the study of adjuvant therapy. A prospectively, randomized, controlled clinical trial was performed in order to determine whether pre-operative and intraoperative radiotherapy improves treatment results of gastrectomy for stomach carcinoma.
