title: [Mass screening in the diagnosis of precancerous diseases of the stomach].
abstract: The authors emphasize the importance of diagnosticating and systematic observation of cancer preneoplasms for earlier detection of stomach cancer. For this purpose a clinico-laboratory test for thiocompounds in the urine has been used. The former has been found to be convenient for mass screening because of its prompt performance. Nearly 3.5% of 10000 healthy persons under examination have been screened by means of the mentioned test. The effectiveness of the test was checked up through an x-ray examination of the stomach of the screened persons, i.e. of those who have shown the positive result. Cancer preneoplasms have been detected in 32.5% of the x-ray screened persons. It is concluded that the used mass screening test, followed by an x-ray examination of those patients who showed a positive result for thiocompounds in the urine, could be used as a pattern for the detection of pretumor lesions.
