Abstract

Objectives: To determine diagnostic value of modified Liquid Based Brush Biopsy technique. Study design: 26 oral premalignant and malignant lesions in 25 patients (12 females; 54.23±19.77 years and 13 males; 53.77±15.43 years) underwent Modified (Liquid Based) Brush Biopsy and scalpel biopsy simultaneously from the same area. Results: There were 16 positive and 10 negative brush biopsy results, with no inadequate readings. Histological findings were compatible with oral leukoplakia(n=5)with dysplasia, Oral lichen planus and lichenoid reaction(n=7) (with or without dysplasia)oral squamous cell carcinoma(n=11),verrucous carcinoma(n=1) and granular cell tumors(n=2). Sensitivity, specificity, positive predictive value, negative predictive value, positive diagnostic likelihood ratio(LR+) and negative diagnostic likelihood ratio(LR-) were 88.8%,100%,100% , 80%, infinity and 0.11 respectively(no false positive results). Conclusion: It is the first attempt to do LBC (liquid based cytology) with a specialized oral brush. Our results show that modified technique is a useful tool for screening of oral premalignant and malignant lesions. © Medicina Oral S. L.
