Evaluation of the diagnostic value of a Modified Liquid-Based Cytology using OralCDx Brush in early detection of oral potentially malignant lesions and oral cancer
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, …
The expression of heat shock proteins 27 and 105 in squamous cell carcinoma of the tongue and relationship with clinicopathological index
Introduction: In oral cavity, the tongue is the most common site prone to development of squamous cell carcinoma (SCC). Considering malignant transformation as a cellular stress, the expression of heat shock proteins (HSPs) may be affected in this process. In this study we assessed the expression of HSP105 and HSP27 as two of the most interested stress proteins and investigated their relationship with grade and stage of the tongue SCC. Material and Methods: Fifty-six specimens including 31 early and 25 advanced tongue SCC were gathered. All specimens were graded histologically from I to III. Sixteen sections of normal oral mucosa were used as control group. The cellularity and intensity of …
