 We examined 101 superficial pharyngeal cancer patients with 131 lesions treated by endoscopy between 2002 and 2014. In all patients, the lesions were detected during endoscopy of the upper gastrointestinal tract. The detection method included initial white-light imaging in 77 lesions(59%)and NBI(narrow-band imaging)in 45 lesions(34%). In the remaining nine lesions(7%)that were unclear on conventional NBI, the lesions were detected by iodine staining upon treatment of another lesion. The classification of 131 superficial pharyngeal cancer lesions included type 0-I in five lesions(4%), mixed type 0-I in two lesions(2%), type 0-IIa in 53 lesions(40%), type 0-IIa+IIb in 12 lesions(9%), type 0-IIa+IIc in five lesions(4%), type 0-IIb in 37 lesions(28%), type 0-IIc in 14 lesions(10.5%), type 0-IIc+IIa in one lesion(1%), and type 2-like in two lesions(1.5%), with protruding lesions accounting for 60%. According to the invasion depth, we found intraepithelial carcinomas in 106 lesions(81%)and subepithelial invasion in 25 lesions(19%). Intraepithelial carcinomas included flat type IIb, type IIa without surface irregularities, and type IIc without surrounding elevation, whereas cancer with subepithelial invasion included type 0-I with high elevation, type 0-IIa+IIc with depressed area in an elevated lesion, type 0-IIc with marginal elevation, and lesions with clear irregularities, such as type 2-like. In cancers with subepithelial invasion, positive vascular invasion was observed in a total of four patients(15%), including two patients with type 0-I lesions and two patients with type 2-like lesions.
