  • Title: Use of the esophageal balloon in the diagnosis of carcinomas of the head, neck and upper gastrointestinal tract.

    Journal: Acta Cytol; 1984; 28(1):9-15. PubMed ID: 6582746.
    Abstract:
    A study was undertaken to demonstrate the safety, efficacy and value of esophageal balloon cytology in the diagnosis of esophageal lesions and as a tool in screening a high-risk patient population. The sampling was performed 110 times on 96 patients, 11 with known obstructive carcinoma of the esophagus and 85 thought to be at risk for esophageal cancer: 74 with treated or untreated cancer of the head and neck area and 11 with dysphagia or other findings requiring clarification. The method was well tolerated by the patients, and the cytologic smears were of excellent quality. Malignant or suspicious cells were found in smears from 7 to 11 patients with documented esophageal cancer and in 7 of 85 patients believed to be at risk. In the latter group there were three unsuspected recurrent cancers of the oropharyngeal region and one unsuspected carcinoma in situ of the esophagus. There were no false-suspicious or false-positive results. This noninvasive technique of esophageal cytology obviously deserves additional trials as an adjunct in the diagnosis of carcinoma of the head and neck and upper gastrointestinal tract, especially in high-risk patients.
