METHOD OF COMBINATION TREATMENT OF STOMACH CANCER Russian patent published in 2012 - IPC A61B17/00 A61N5/10 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, oncology, radiation therapy and surgery. At first, a primary stomach tumour and a regional metastasis area are treated with a preoperative radiation therapy that involves the exposure to daily impact radiation for 5 days by a graduated single base dose 2.45-2.55 Gy every 4-6 hours to total basic dose 24.5-25.5 Gy generated by two opposing fields. It is followed by a radical surgical intervention with D2 lymph node dissection. A radiation field former - an applicator - is fixed in an operative wound, and intraoperative exposure of the extracted tumour bed areas and the regional metastasis areas are carried out in dose 19-20 Gy with accelerated electron energy 8.0-12 MeV. A gastroesophagoenterostomy follows after the radiation session is completed.

EFFECT: method provides devitalisation of the tumour cells, liquidation of locoregional relapses, decreased rate of the onset of remote metastases and reduced risk of damaging surrounding tissues and organs sensitive to ionising radiation.
