Oral Surg Oral Med Oral Pathol Oral Radiol. 2020 Sep;130(3):258-263. doi: 10.1016/j.oooo.2020.04.809. Epub 2020 Jun 25.

Abstract

Objective: In oral squamous cell carcinoma (OSCC), 20% of patients experience local recurrences. In this study, the addition of autofluorescence to a standard incandescent light examination was evaluated to enhance detection rates of recurrences in OSCC.

Study design: Patients with OSCC who underwent follow-up examinations were included in this prospective cohort study. All patients (with or without recurrences) were examined clinically and with autofluorescence (using VELscope; Mectron, Cologne, Germany) and biopsy was used to examine suspect lesions for recurrences. Variables likely to influence results were analyzed. An analysis of dependencies, a general log-linear analysis, and a binary regression analysis were performed using SPSS version 26 (SPSS Inc., Chicago, IL).

Results: The study included 195 patients and in 39 cases a biopsy was performed. Results showed significantly more recurrences with the addition of autofluorescence to the usual clinical examination (P ≥ .5). Sensitivity was 95.2% and specificity was 100%.

Conclusions: This study showed the advantages of adding autofluorescence to routine clinical assessments in OSCC follow-up examinations.

Clinical trial registration: German Clinical Trials Register DRKS-ID: DRKS00004836.
