Background and Aim: Transnasal endoscopy (TE) is being widely used because it is associated with lower pain and better image quality. This retrospective cohort study aimed to evaluate the usefulness of TE with image‐enhanced endoscopy (IEE) in estimating the depth and thickness of superficial hypopharyngeal squamous cell carcinoma (HPSCC).
Methods: Between November 2016 and February 2021, 19 subjects (23 HPSCC lesions) were preoperatively examined using TE with IEE in our facility, and endoscopically resected tissue was pathologically evaluated. Three specialists retrospectively reviewed the endoscopic images and identified two groups, namely, Dot (Group D) wherein only background coloration and dot‐like blood vessels were observed, and Non‐Dot (Group ND) in which blood vessels other than dot‐like blood vessels were observed. Clinicopathological characteristics were also assessed and compared between the two groups.
Results: Median age of the cohort was 67 years (range, 54-90 y), and both epithelial (EP, n = 10) and subepithelial lesions (SEP, n = 13) were found. There were significantly more EP cancers in group D and significantly more SEP cancers in Group ND (p < 0.05). Tumor thickness tended to be greater in group ND (avg, 813 um) than in group D (avg, 433 um), although the difference was not significant.
Conclusions: TE with IEE may be useful for estimating the depth and thickness of superficial HPSCC.
