title: [Gastroscopy plus cytology for the diagnosis of gastric cancer or precancerous diseases--report of 127 cases].
abstract: One hundred and twenty-seven patients with gastric tumor or precancerous diseases were examined by gastroscopy plus cytology, and the results were compared with that of histopathology after operation. Out of 127 cases, 70 were diagnosed as gastric cancer (15 cases as early cancer, 55 as advanced cancer). The positive rate for early cancer was 21.4%, it comprised 11.2% of all gastric cancers diagnosed by gastroscopy during the same period. The preoperative positive rate of early gastric cancer was 100% (13/13) as examined by the combination of touch, brush cytology and mucosal biopsy. The combined method may increase the positive rate and the accuracy, not only for advanced but also for early gastric cancers. It is suggested that the combination of these methods be routinely used in the diagnosis of suspicious cancer in the gastric mucosa.
