Evaluation of brush cytology as an independent technique for detection of esophageal carcinoma
K Dowlatshahi, DB Skinner, TR DeMeester, L Zachary, M Bibbo and GL Wied
In this study the accuracy of indirect brush cytology for detection of
esophageal carcinoma is evaluated against current standard methods of
diagnosis and is compared with the known accuracy rate of endoscopically
directed brush cytology. A standard endoscopic nylon brush placed inside a
nasogastric tube was used in 203 patients with various esophageal problems.
Correct diagnosis was made in 78% of cancers, 95% of potentially
premalignant cases, and 100% of cases of normal esophageal mucosa with both
indirect and directed brushing procedures. The technique meets most
requirements of a new screening procedure as being simple, safe (no
complications), relatively inexpensive, and acceptable to patients (98%
compliance). Currently it is employed to monitor high-risk esophageal
conditions and post- treatment courses of patients with pharyngoesophageal
tumors for local recurrence or a new primary lesion in the esophagus.
