Brief summary
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.
Detailed description
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.

Eligibility
Inclusion criteria
* From the archive, any patient who presents with clinically evident oral lesions and biopsy-proven dysplasia (punch or scalpel biopsies; any grade or classification system) * Patients with initial oral lesions with epithelial atypia suspicious for neoplasia, with: * No histological evidence of cancer with clinical follow-up data for a period of at least five years; or * OSCC development (histologic or documented evidence of invasive cancer). * Patients who had archived biopsy tissue blocks of a previous oral lesion(s) meeting the above criteria and retained at the same clinical center.
Exclusion criteria
* Patients with oral lesions or dysplasia with no indication of OSCC development or follow-up data of less than five years in non-OSCC patients. * Patients diagnosed with oral epithelial dysplasia concomitant with OSCC at the time of the biopsy's original pathology report or a subsequent clinical note of cancer progression within three months post-biopsy.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Sensitivity and Specificity | 5 years | Standard measures of accuracy calculated using cross-tabulation of predicted risk category and confirmed cancer progression over a 5-year period from biopsy |
| Survival analysis | 5 years | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| AUC | 5 years | Area under the receiver operator curve |
| C-index (Harrell's) | 5 years | 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. |
