The purpose of this study is to validate the ability of the STRATICYTE™ predictive model to predict the transformation of oral potentially malignant disorders (OPMDs) to oral squamous cell carcinoma (OSCC) in a retrospective cohort of patients who received biopsies.

The study objectives are to:

1. Evaluate STRATICYTE™ sensitivity and specificity in a cohort of patients that meet the inclusion/exclusion criteria.
2. Identify patient and clinical characteristics influencing the sensitivity and specificity of the STRATICYTE™ model.
3. Estimate the correlation between STRATICYTE™ outcome and time to a positive diagnosis of oral cancer.

Evaluation of Oral Potentially Malignant Disorders (OPMDs) With STRATICYTE™

Standard measures of accuracy calculated using cross-tabulation of predicted risk category and confirmed cancer progression over a 5-year period from biopsy

Kaplan-Meier analyses to compare time to a positive diagnosis of oral cancer between patients/biopsies with a STRATICYTE™ classification of Low- and Elevated-Risk.

From all possible pairs of patients, compute the number of concordant and discordant pairs. Compute C-index as the proportion of all possible pairs that are concordant.

The purpose of this observational study is to evaluate the utility of the S100A7 immunohistochemistry signature-based assessment - STRATICYTE - in determining the risk of progression to cancer of clinically suspicious oral lesions.

Background: The standard of care for potentially premalignant oral epithelial lesion (PPOEL) risk assessment for progression to cancer is dysplasia grading by histopathology. With significant overlap between dysplasia grades and high inter- and intra-observer variations, dysplasia grading alone has been shown to be inadequate as a prognostic tool. To investigate the utility of the S100A7 immunohistochemistry signature-based assessment - STRATICYTE - in the early diagnosis of invasive oral cancer, a prospective multi-center observational study was designed with specimens obtained from community-based practices.

Methods: Patients that qualify to enroll in the study will be assessed for both standard of care histopathological assessment for dysplasia grade and STRATICYTE risk assessment, and followed for up to 60 months (from initial biopsy) to determine the outcome of their oral lesion(s).
