The results obtained from diagnosis and treatment of six patients with cardioesophagic junction cancer, diagnosed by histopathologic study during surgery, are presented. Three patients presented with diaphragmatic hernia as well. Esophagogastroduodenal roentgenological study was interpreted as neoplasia in three patients only; it was supposed that the other three patients had a benign esophageal stricture. Endoscopy oriented the malignity diagnosis in four patients, and for benign lesion in the other two. Biopsy showed malignant lesion in three patients and it was negative in the other three. Exfoliative cytology was positive in four patients and negative in two. Esophagogastric resection was done in four patients. One of them died post-operatively. The other have survived 36, 22 and 16 months.
