Abstract

OBJECTIVES: We observed that a prominent strip of depapillated mucosa surrounded tongue carcinomas. This study evaluates its correlation with other prognosticating factors.

STUDY DESIGN: This prospective study included treatment naïve squamous carcinomas of tongue operated between January and December 2018. Patients with any disorder that could possibly influence the presence of depapillation were excluded, and stratified based on the presence (Group A) and absence (Group B) of depapillation surrounding the tumor. Data sets included biochemical test, clinical variables, and postoperative histologic features. A multivariate logistic regression was performed to identify the association of these factors.

RESULTS: Group A comprised 62.8% (n = 76/121) of the entire cohort, which was reasonably distributed for tumor and host factors. A greater number of inadequate margins were found in Group A. Clinical factors significantly associated with depapillation included higher preoperative platelet count (>250.5), infection rates, and Clavien-Dindo scores. Perineural invasion and lymphocytic infiltrate were significantly associated with Group A, particularly in early tumors (P = .040).

CONCLUSIONS: Local invasion and inflammation results in papilla dysfunction clinically appearing as depapillation, leading to accumulation of neurotransmitters and a favorable environment for neural infiltration. We suggest peritumoral depapillation to be a clinical surrogate for perineural invasion, especially in early tongue cancers.
