This excerpt has been provided in the absence of an abstract.

During the period april, 1955, through december, 1963, esophageal exfoliative cytology was performed in 210 patients and gastric exfoliative cytology in 2,127 patients, with adequate follow-up of at least 6 months.

Among the 210 cases of esophageal cytology, there were 64 proven malignant tumors of the esophagus and cardia. The positive cytological report was correct in 56, an accuracy of 87%. The 2,127 cases of gastric cytology included 215 malignant tumors. The cytological report was correct in 189, an accuracy of 86%. The over-all accuracy of the negative reports for both organs was practically the same, approximately 98%.
