ABSTRACT
BACKGROUND:
Magnifying endoscopy with narrow band imaging (ME-NBI) is useful to diagnose invasion depth of superficial esophageal cancer. The purpose of this study was to evaluate the utility of ME-NBI of superficial pharyngeal cancer.METHODS:
Between April 2008 and June 2012, 146 lesions in 104 patients who underwent ME-NBI and en bloc resection were retrospectively analyzed. Based on magnifying endoscopic classification, proposed by the Japan Esophageal Society, microvasculature type was classified into B1, B2, and B3.RESULTS:
B1 alone, B2, and B3 were observed in 128, 14, and 4 lesions, respectively. The frequency of subepithelial cancer were 20.3% (26 of 128), 78.6% (11 of 14), and 100% (4 of 4), respectively (p < .05). Mean invasion distance were 650 µm, 720.0 µm, and 2256.5 µm. Positive and negative predictive value for diagnosing subepithelial cancer based on the presence of B2 or B3 was 83.3% (15 of 18) and 79.7% (102 of 128).CONCLUSION:
ME-NBI is useful to determining invasion depth of superficial pharyngeal cancer.Palabras clave
