title: [Diagnosis of cancer of the esophagus by sponge smears (II)].
abstract: Forty-four patients with carcinoma of the esophagus, 21 with cancer of the gastric fundus with invasion of gastroesophageal junction, and 28 controls with non-tumoral esophageal problems were studied by the sponge smear technique, an effective procedure for cytologyc diagnosis of esophageal tumors. Several advantages of this technique over esophageal washings are described and its results are favorably compared with those obtained by esophageal washings.
