Abstract
OBJECTIVES
The diagnostic performance of cytology in esophageal squamous cell carcinoma (ESCC) is meticulously described.
METHODS
Cytological and biopsy specimens were prospectively taken during esophagogastroduodenoscopy of 123 individuals in 2013 and 2014. Cytology samples were maintained in preservative fluid until processing and biopsies were formalin-fixed and paraffin-embedded.
RESULTS
Based on endoscopic biopsy results, 70 cases were positive for ESCC whilst 53 were negative for cancer. In addition, brush cytology showed high sensitivity and specificity (98.57 and 96.23%, respectively) in detecting the disease, and high accuracy (97.5%) comparable to that provided by histopathology which is the accepted gold standard.
CONCLUSION
Brush cytology specimens preserved in liquid medium may be a good alternative for ESCC diagnosis.
