[A case report of advanced gastric cancer responsive to radiotherapy and CDDP arterial injection].

A 48-year-old-male patient with advanced gastric cancer, which extended from corpus to antrum of the stomach and metastasized to the left lobe of the liver, was treated with radiotherapy combined with CDDP arterial injection. Total irradiation and CDDP dosage was 50 Gy/25 f and 150 mg (75 mg/mal/body), respectively. The regression of the tumor was remarkable. For inoperable advanced gastric cancer, radiotherapy combined with anticancer drugs proved a worthwhile therapy, and it was necessary to use the pharmacological characteristics of the drugs.
