Diagnostics of a cancer of a stomach with radioactive zone

This method was proposed in order to identify early cancer of the stomach. It is known that the malignant tumors of the stomach accumulate radioactive phosphorus to a much greater extent than the surrounding unchanged mucosa. However, to use this method for direct detection of cancer of the stomach as a study area close unable to bring the standard counter.
K. I. Myshkin (1955) proposed to use for the detection of gastric cancer study of radioactivity wash water. With the same purpose, apply and flexible intracavitary beta probe. For days sick in the stomach put the probe concluded in latex hood. The contact of the detector with the investigated area is achieved by using dosed compression in the optimal position of the patient. The level of radioactivity over the tumor is expressed in percentage to the intensity of radiation from the unchanged part of the mucous. The stomach is washed with 1 liter of water and 8 and 20 hours after administration of radioactive phosphorus in the lavage determine the elimination of the isotope in percentage to put the dose. 52 investigated by the author in 23 patients histologically confirmed gastric cancer. 14 the cancer was confined to the mucosa and muscle shell without metastases. The average level of excretion R these entities amounted to 3,2 ±0.9%, and over the cancer, the level of radioactivity was increased by 150-200%. Because clinical and x-ray data was not sufficiently clear, the results of the radiological researches have allowed to choose the correct treatment tactics.
Developed the method of diagnostics of a cancer of a stomach with radioautographic definition of increased sediments R in life (Akkermann). With this method as radioautographic plate is used thin rubber cylinder covered elastic photosensitive emulsion. According to the author, this technique has a useful value for the diagnosis.
