The results of combined radiation and chemotherapy for the treatment of gastric carcinoma are reviewed. A small amount of postoperative adjuvant combined treatments of the curatively resected gastric carcinoma was performed which do not suggest any advantage of treatment compared to observation. For locally advanced and unresectable gastric carcinoma 5-fluorouracil or ftorafur was administered simultaneously to local irradiation in several phase-II studies. The response rates of 37%-58% and one year survival of 45%-72% do not suggest an advantage of combined modality compared to the one way treatment. The FAM, FAMe or FAB regimen was also used and obviously do not improve the results of combined modality treatment. A small but well conducted prospective randomized trials compared radiotherapy with and without chemotherapy or chemotherapy with and without radiotherapy. Recent results from different cooperative groups failed to improve the treatment results in terms of response and survival.
