We have observed, just as have other investigators, that the gastric exfoliative cytology technique is a valuable aid in diagnosing gastric lesions. We have come to rely upon this technique very much in the differential diagnosis of lesions of the gastric mucosa. The value of a negative cytology report, we feel, is important in surveying patients with known gastric lesions or in patients with upper gastrointestinal symptoms. We have found that the accuracy of a negative cytology report is above 90 per cent. The accuracy of our positive cytology reports is much the same that has been reported in the current literature and is between 80 and 90 per cent. In conclusion, it should be emphasized that these are some of our preliminary experiences. Time, and accumulation of additional data on many patients, will be necessary for full evaluation of the role of gastric exfoliative cytology in the diagnosis of gastric lesions and its true worth as a screening device.
