Endoscopic brushing cytology and biopsy in the diagnosis of upper gastrointestinal tract lesions. A study of 350 cases

Endoscopic brushing cytology and biopsy in the diagnosis of upper gastrointestinal tract lesions. A study of 350 cases

Acta Cytologica 32(4): 455-460

Direct-vision endoscopic examination conducted on 4,000 patients for persistent upper gastrointestinal (GI) complaints over a period of five years revealed 350 visible lesions that were subjected to brushing cytology and biopsy. Cytologic examination of brushing smears from all 350 cases showed malignant cells in 67 (19.14%), cells suggesting benign polypoid neoplasms in 4 (1.14%), ulcerative and reparative features with attendant atypias in 186 (53.14%), inflammatory findings in 91 (26%) and false-negative findings in 2 cases (0.57%). Only 259 (74%) of the visible lesions were also subjected to endoscopic biopsy. Of the 67 patients with positive cytology, 52 were judged positive on the biopsy specimens; the 2 false-negative cytologic reports were confirmed as positive by biopsy. In four patients with gastric ulcers, malignant cells were seen along with gastric repair cells. This study indicates that brushing cytology is very useful in detecting benign ulcerative lesions with their atypias, a feature that could be useful in monitoring and controlling lesions in high-risk groups of patients, such as in India. In this study, endoscopic brushing cytology gave a better diagnostic yield than did endoscopic tissue biopsy. However, the two techniques are complementary for the diagnosis of upper GI malignancies.
