[Ultrasonic luminescence of blood in stomach cancer]

Ultrasonic luminescence of blood plasma was studied in 428 cases of cancer, precancer and non-tumor diseases of the stomach and other viscera. The authors were the first to establish a relatively short duration of sound-luminescence of plasma in gastric cancer. Those alterations were considered indicative of neoplasm. Disease was misdiagnosed in 15.5% of cases of gastric pathology: cancer was not detected in 12.7% whereas tumor was erroneously diagnosed in 18.5% of patients with complicated gastric ulcer and other non-tumor pathology. Application of sound-luminescent method in combination with X-ray examination assured reliable diagnosis of gastric cancer in 95.1%. The method appeared instrumental in diagnosing other cancers as well.
