Brush Cytology with Immunocytochemical Evaluation of VEGF Expression versus Biopsy in Clinically Precancerous Laryngeal Lesions: Can We Diagnose Laryngeal Cancer Only with Brush Cytology?

Table 3

The correlation between the results of exfoliative cytology and the immunocytochemical analysis of VEGF expression in 30 patients with precancerous or suspected malignant laryngeal lesions.

	VEGF expression	0	1	2	3
Cytologic examination	Benign lesions	5	—	—	—
	Atypia/moderate dysplasia (suspicious)	1	1	2	3
	Malignancy	4	4	4	6
