Recently, new promising anti-tumor agents such as TS-1, taxanes, and CPT-11 have been approved for gastric cancer treatment. These agents showed a better response and may contribute to a patient's survival and quality of life. However, there are cases with advanced and recurrent gastric cancer that are resistive or tolerant to these agents. We report two cases in which the patients had suffered symptomatic local recurrence during the chemotherapy. Consequently, they had been treated with radiotherapy in order to improve their clinical status. We also discuss the significance of radiotherapy in gastric cancer.
