METHOD FOR APPLYING POSTOPERATIVE RADIATION THERAPY IN STOMACH CARCINOMA CASES Russian patent published in 2006 - IPC A61N5/10 

FIELD: medicine.

SUBSTANCE: method involves applying preradiation topometry with irradiation fields being formed. Irradiation is carried out 5 times a week from two opposite fields to reach total radiation dose of 50 Gy under unit focal dose being equal to 2 Gy. The irradiation is applied from rectangular fields having the following boundaries. The lower one is upper edge of the second lumbar vertebra body. The upper boundary is 10 cm higher than the lower one. The right one is 2 cm far from vertebral column contour to the right. The left boundary is 15 cm far from the right one. Removed stomach bed, paracardial lymph nodes, lymph nodes of lesser omentum, gastropancreatic ligament along the left gastric and splenic arteries to the splenic porta and celiac lymph nodes. The tumor propagating over abdominal or supradiaphragmatic esophageal segments, additional anterior and posterior rectangular irradiation fields are formed with paraesophageal and bifurcational nodes being included into the zone.

EFFECT: reduced risk of complications after radiation treatment; maximum amount of healthy tissues retained.
