[Potentialities of x-ray diagnosis in improving the diagnosis of oncologic diseases in outpatient clinics]. / Vozmozhnosti rentgenologii v uluchshenii poliklinicheskoi diagnostiki onkologicheskikh zabolevanii.

The authors analyze the possibilities of improving the prehospital diagnosis of the most prevalent oncologic diseases (tumors of the lungs, stomach, large intestine, mammary gland) that may be effectively detected by modified methods of x-ray and x-ray fluorographic examinations. The x-ray diagnostic service of health centers is regarded as a most important component in the system of prehospital diagnosis. A program of reorganization of this service is suggested, that will help reorient its activities to purposeful screening examinations that will altogether improve the detection of a number of oncologic diseases.

A current approach to the perfection of the diagnosis of colonic tumors is proposed in patients at risk by means of introduction into the ambulatory health care system (polyclinics, diagnostic centers) of standardized colonic fluorography followed by endoscopy in necessary cases. The main organizational and methodological principles of the use of colonic fluorography were worked out as a method of screening to reveal colonic tumors. It is suggested that such new elements as the "prescopic stage" realized outside the radiation zone, automated distant air inflation into the colon and so forth may be introduced in colonic fluorographic examination. Experience gained with over 2065 colonic fluorographies on a special fluorograph and 1120 examinations on routine x-ray diagnostic units fitted with the amplifier and a photochannel (79 cases of colonic carcinoma and 89 benign tumors were identified) evidences that the program of making colonic fluorography enables one to significantly improve the diagnosis of colonic tumors.

The experience of running a specialized photoroentgenographic station of the Institute is discussed. The total of 4,052 examinations (healthy subjects for prophylaxis and patients with gastrointestinal complaints) were carried out. The percentage of early gastric cancer diagnosed by means of prophylactic photoroentgenography was significantly higher than that yielded by standard out-patient examination procedures. Such centers should be set up primarily at large polyclinics, regional hospitals, etc.
