Cytological Screening for Early Diagnosis of Precancerous or Cancerous Lesions of Oral Cavity (Cytobuccale)

April 16, 2019 updated by: University Hospital, Toulouse

Interest of Cytological Screening for Early Diagnosis of Precancerous or Cancerous Lesions of Oral Cavity by Transepithelial Brushing in Liquid-based

Prospective study of diagnosis validation of a cytological technique. 200 patients with oral cavity cancerous and precancerous lesions will be enrolled.

A cytological sample of the lesion will be performed by transepithelial brushing ( Orcellex® Rovers brush) in cytology liquid-based technology (methode ThinPrep 2000 (Hologic®)). A microscopic double blind reading will be performed. A biopsy sampling will be carried out in accordance with current strategy of screening. The brushing diagnosis quality will be compared to the biopsy which is the gold standard.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Diagnostic validity of lesion (Bethesda system, 2001)
Time Frame: baseline
Diagnostic validity (specificity and sensibility, the classification of lesions is performed according Bethesda system, 2001 and the reference is the histology of biopsy of lesion
baseline

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Diagnostic validity - predictive value (positive and negative)
Time Frame: baseline
Calculation of predictive value (positive and negative) of cytology / the reference is histology of biopsy
baseline
Feasibility of cytology
Time Frame: Baseline
sample rate not satisfactory= hemorrhage hiding the cells of interest
Baseline
Feasibility of cytology
Time Frame: Baseline
sample rate not satisfactory : low cellularity of the material
Baseline
Reproducibility intra and inter observers (coefficient of kappa de cohen)
Time Frame: Baseline
reproducibility intra and inter observers of cytology interpretation (kappa de cohen)
Baseline
