Method of pre-radiation preparation for administration adjuvant radiation therapy to gastric cancer patients

The method of pre-radiation preparation for administering adjuvant radiation therapy to patients with advanced gastric cancer using designed devices for radiation field formation has been proposed. Radiation fields have clear skeletotopic orientation that significantly accelerates topometric preparation and reduces radiation load on patients and medical personnel, congruence of anterior and posterior field is achieved. The radiation field coves the tumor bed and areas of potential regional metastatic spread.
